First Principles by Herbert Spencer 1820-1903 Part I The Unknowable Chapter 1 Religion and Science 1. We too often forget that not only is there "a soul of goodness in things evil," but very generally also, a soul of truth in things erroneous. While many admit the abstract probability that a falsity has usually a nucleus of verity, few bear this abstract probability in mind, when passing judgment on the options of others. A belief that is proved to be grossly at variance with fact, is cast aside with indignation or contempt; and in the heat of antagonism scarcely any one inquires what there was in this belief which commended it to men's minds. Yet there must have been something. And there is reason to suspect that this something was its correspondence with certain of their experiences: an extremely limited or vague correspondence perhaps, but still, a correspondence. Even the absurdest report may in nearly every instance be traced to an actual occurrence; and had there been no such actual occurrence, this preposterous misrepresentation of it would never have existed. Though the distorted or magnified image transmitted to us through the refracting medium of rumour, is utterly unlike the reality; yet in the absence of the reality there would have been no distorted or magnified image. And thus it is with human beliefs in general. Entirely wrong as they may appear, the implication is that they originally contained, and perhaps still contain, some small amount of truth. Definite views on this matter would be very useful to us. It is important that we should form something like a general theory of current options, so that we may neither over-estimate nor under- estimate their worth. Arriving at correct judgments on disputed questions, much depends on the mental attitude preserved while listening to, or taking part in, the controversies; and for the preservation of a right attitude, it is needful that we should learn how true, and yet how untrue, are average human beliefs. On the one hand, we must keep free from that bias in favour of received ideas which expresses itself in such dogmas as "What every one says must be true," or "The voice of the people is the voice of God." On the other hand, the fact disclosed by a survey of the past that majorities have usually been wrong, must not blind us to the complementary fact that majorities have usually not been entirely wrong. And the avoidance of these extremes being a pre-requisite to catholic thinking, we shall do well to provide ourselves with a safeguard against them, by making a valuation of opinions in the abstract. To this end we must contemplate the kind of relation that ordinarily subsists between opinions and facts. Let us do so with one of those beliefs which under various forms has prevailed among all nations in all times. 2. Early traditions represent rulers as gods or demigods. By their subjects, primitive kings were regarded as superhuman in origin and superhuman in power. They possessed divine titles, received obeisances like those made before the altars of deities, and were in some cases actually worshipped. Of course along with the implied beliefs there existed a belief in the unlimited power of the ruler over his subjects, extending even to the taking of their lives at will; as until recently in Fiji, where a victim stood unbound to be killed at the word of his chief himself declaring, "whatever the king says must be done." In other times and among other races, we find these beliefs a little modified. The monarch, instead of being thought god or demigod, is conceived to be a man having divine authority, with perhaps more or less of divine nature. He retains, however, titles expressing his heavenly descent or relationships, and is still saluted in forms and words as humble as those addressed to the Deity. While in some places the lives and properties of his people, if not so completely at his mercy, are still in theory supposed to be his. Later in the progress of civilization, as during the middle ages in Europe, the current opinions respecting the relationship of rulers and ruled are further changed. For the theory of divine origin there is substituted that of divine right. No longer god or demigod, or even god-descended, the king is now regarded simply as God's vicegerent. The obeisances made to him are not so extreme in their humility; and his sacred titles lose much of their meaning. Moreover his authority ceases to be unlimited. Subjects deny his right to dispose at will of their lives and properties, and yield allegiance only in the shape of obedience to his commands. With advancing political option has come still greater restriction of monarchical power. Belief in the supernatural character of the ruler, long ago repudiated by ourselves for example, has left behind it nothing more than the popular tendency to ascribe unusual goodness, wisdom, and beauty to the monarch. Loyalty, which originally meant implicit submission to the king's will, now means a merely nominal profession of subordination, and the fulfilment of certain forms of respect. By deposing some and putting others in their places, we have not only denied the divine rights of certain men to rule, but we have denied that they have any rights beyond those originating in the assent of the nation. Though our forms of speech and our State-documents still assert the subjection of the citizens to the ruler, our actual beliefs and our daily proceedings implicitly assert the contrary. We have entirely divested the monarch of legislative power, and should immediately rebel against his or her dictation even in matters of small concern. Nor has the rejection of primitive political beliefs resulted only in transferring the power of a autocrat to a representative body. The views held respecting governments in general, of whatever form, are now widely different from those once held. Whether popular or despotic, governments in ancient times were supposed to have unlimited authority over their subjects. Individuals existed for the benefit of the State; not the State for the benefit of individuals. In our days, however, not only has the national will been in many cases substituted for the will of the king, but the exercise of this national will has been restricted. In England, for instance, though there has been established no definite doctrine respecting the bounds to governmental action, yet, in practice, sundry bounds to it are tacitly recognized by all. There is no organic law declaring that a legislature may not freely dispose of citizens' lives, as kings did of old, but were it possible for our legislature to attempt such a thing, its own destruction would be the consequence, rather than the destruction of citizens. How fully we have established the personal liberties of the subject against the invasions of State-power, would be quickly shown were it proposed by Act of Parliament to take possession of the nation, or of any class, and turn its services to public ends, as the services of the people were turned by Egyptian kings. Not only in our day have the claims of the citizen to life, liberty, and property been thus made good against the State, but sundry minor claims likewise. Ages ago laws regulating dress and mode of living fell into disuse, and any attempt to revive them would prove that such matters now lie beyond the sphere of legal control. For some centuries we asserted in practice, and have now established in theory, the right of every man to choose his own religious beliefs, instead of receiving State- authorized beliefs. Within the last few generations complete liberty of speech has been gained, in spite of all legislative attempts to suppress or limit it. And still more recently we have obtained under a few exceptional restrictions, freedom to trade with whomsoever we please. Thus our political beliefs are widely different from ancient ones, not only as to the proper depositary of power to be exercised over a nation, but also as to the extent of that power. Nor even here has the change ended. Besides the average opinions just described as current among ourselves, there exists a less widely-diffused opinion going still further in the same direction. There are to be found men who contend that the sphere of government should be narrowed even more than it is in England. They hold that the freedom of the individual, limited only by the like freedom of other individuals, is sacred. They assert that the sole function of the State is the protection of persons against one another, and against a foreign foe; and they believe that the ultimate political condition must be one in which personal freedom is the greatest possible and governmental power the least possible. Thus in different times and places we find, conceding the origin, authority, and functions of government, a great variety of opinions. What now must be said about the truth or falsity of these opinions? Must we say that some one is wholly right and all the rest wholly wrong; or must we say that each of them contains truth more or less disguised by errors? The latter alternative is the one which analysis will force upon us. Every one of these doctrines has for its vital element the recognition of an unquestionable fact. Directly or by implication, each insists on a certain subordination of individual actions to social dictates. There are differences respecting the power to which this subordination is due; there are differences respecting the motive for this subordination; there are differences respecting its extent; but that there must be some subordination all are agreed. The most submissive and the most recalcitrant alike hold that there are limits which individual actions may not transgress limits which the one regards as originating in a ruler's will, and which the other regards as deducible from the equal claims of fellow-citizens. It may doubtless be said that we here reach a very unimportant conclusion. The question, however, is not the value or novelty of the particular truth in this case arrived at. My aim has been to exhibit the more general truth, that between the most diverse beliefs there is usually something in common, something taken for granted in each; and that this something, if not to be set down as an unquestionable verity, may yet be considered to have the highest degree of probability. A postulate which, like the one above instanced, is not consciously asserted but unconsciously involved, and which is unconsciously involved not by one man or body of men, but by numerous bodies of men who diverge in countless ways and degrees in the rest of their beliefs, has a warrant far transcending any that can be usually shown. Do we not thus arrive at a generalization which may habitually guide us when seeking for the soul of truth in things erroneous? While the foregoing illustration brings home the fact that in opinions seeming to be absolutely wrong something right is yet to be found, it also indicates a way of finding the something right. This way is to compare all opinions of the same genus; to set aside as more or less discrediting one another those special and concrete elements in which such opinions disagree; to observe what remains after these have been eliminated; and to find for the remaining constituent that expression which holds true throughout its various disguises. 3. A consistent adoption of the method indicated will greatly aid us in dealing with chronic antagonisms of belief. By applying it not only to ideas with which we are unconcerned, but also to our own ideas and those of our opponents, we shall be enabled to form more correct judgments. We shall be led to suspect that our convictions are not wholly right, and that the adverse convictions are not wholly wrong. On the one hand, we shall not, in common with the great mass of the unthinking, let our creed be determined by the mere accident of birth in a particular age on a particular part of the Earth's surface, while, on the other hand, we shall be saved from that error of entire and contemptuous negation, fallen into by most who take up an attitude of independent criticism. Of all antagonisms of belief the oldest, the widest, the most profound, and the most important, is that between Religion and Science. It commenced when recognition of the commonest uniformities in surrounding things, set a limit to all-pervading superstitions. It shows itself everywhere throughout the domain of human knowledge; affecting men's interpretations alike of the simplest mechanical accidents and the most complex events in the histories of nations. It has its roots deep down in the diverse habits of thought of different orders of minds. And the conflicting conceptions of Nature and Life which these diverse habits of thought severally generate, influence for good or ill the tone of feeling and the daily conduct. A battle of opinion like this which has been carried on for ages under the banners of Religion and Science, has generated an animosity fatal to a just estimate of either party by the other. Happily the times display an increasing catholicity of feeling, which we shall do well to carry as far as our natures permit. In proportion as we love truth more and victory less, we shall become anxious to know what it is which leads our opponents to think as they do. We shall begin to suspect that the pertinacity of belief exhibited by them must result from a perception of something we have not perceived. And we shall aim to supplement the portion of truth we have found with the portion found by them. Making a rational estimate of human authority, we shall avoid alike the extremes of undue submission and undue rebellion shall not regard some men's judgments as wholly good and others as wholly bad; but shall, contrariwise, lean to the more defensible position that none are completely right and none are completely wrong. Preserving, as far as may be, this impartial attitude, let us then contemplate the two sides of this great controversy. Keeping guard against the bias of education and shutting out the whisperings of sectarian feeling, let us consider what are the a priori probabilities in favour of each party. 4. The general principle above illustrated must lead us to anticipate that the diverse forms of religious belief which have existed and which still exist, have all a basis in some ultimate fact. Judging by analogy the implication is, not that any one of them is altogether right, but that in each there is something right more or less disguised by other things wrong. It may be that the soul of truth contained in erroneous creeds is extremely unlike most, if not all, of its several embodiments; and indeed if, as we have good reason to assume, it is much more abstract than any of them, its unlikeness necessarily follows. But some essential verity must be looked for. To suppose that these multiform conceptions should be one and all absolutely groundless, discredits too profoundly that average human intelligence from which all our individual intelligences are inherited. To the presumption that a number of diverse beliefs of the same class have some common foundation in fact, must in this case be added a further presumption derived from the omnipresence of the beliefs. Religious ideas of one kind or other are almost universal. Grant that among all men who have passed a certain stage of intellectual development there are found vague notions concerning the origin and hidden nature of surrounding things, and there arises the inference that such notions are necessarily products of progressing intelligence. Their endless variety serves but to strengthen this conclusion: showing as it does a more or less independent genesis showing how, in different places and times like conditions have led to similar trains of thought, ending in analogous results. A candid examination of the evidence quite negatives the supposition that creeds are priestly inventions. Even as a mere question of probabilities it cannot rationally be concluded that in every society, savage and civilized, certain men have combined to delude the rest in ways so analogous. Moreover, the hypothesis of artificial origin fails to account for the facts. It does not explain why under all changes of form, certain elements of religious belief remain constant. It does not show how it happens that while adverse criticism has from age to age gone on destroying particular theological dogmas, it has not destroyed the fundamental conception underlying those dogmas. Thus the universality of religious ideas, their independent evolution among different primitive races, and their great vitality unite in showing that their source must be deep-seated. In other words, we are obliged to admit that if not supernaturally derived as the majority contend, they must be derived out of human experiences, slowly accumulated and organized. Should it be asserted that religious ideas are products of the religious sentiment which, to satisfy itself, prompts imaginations that it afterwards projects into the external world, and by-and-by mistakes for realities, the problem is not solved, but only removed farther back. Whence comes the sentiment? That it is a constituent in man's nature is implied by the hypothesis, and cannot indeed be denied by those who prefer other hypotheses. And if the religious sentiment, displayed constantly by the majority of mankind, and occasionally aroused even in those seemingly devoid of it, must be classed among human emotions, we cannot rationally ignore it. Here is an attribute which has played a conspicuous part throughout the entire past as far back as history records, and is at present the life of numerous institutions, the stimulus to perpetual controversies, and the prompter of countless daily actions. Evidently as a question in philosophy we are called on to say what this attribute means; and we cannot decline the task without confessing our philosophy to be incompetent. Two suppositions only are open to us; the one that the feeling which responds to religious ideas resulted, along with all other human faculties, from an act of special creation; the other that it, in common with the rest, arose by a process of evolution. If we adopt the first of these alternatives, universally accepted by our ancestors and by the immense majority of our contemporaries, the matter is at once settled: man is directly endowed with the religious feeling by a creator; and to that creator it designedly responds. If we adopt the second alternative, then we are met by the questions What are the circumstances to which the genesis of the religious feeling is due? and What is its office? Considering, as we must on this supposition, all faculties to be results of accumulated modifications caused by the intercourse of the organism with its environment, we are obliged to admit that there exist in the environment certain phenomena or conditions which have determined the growth of the religious feeling, and so are obliged to admit that it is as normal as any other faculty. Add to which that as, on the hypothesis of a development of lower forms into higher the end towards which the progressive changes tend, must be adaptation to the requirements of life, we are also forced to infer that this feeling is in some way conducive to human welfare. Thus both alternatives contain the same ultimate implication. We must conclude that the religious sentiment is either directly created or is developed by the slow action of natural causes, and whichever conclusion we adopt requires us to treat the religious sentiment with respect. One other consideration should not be overlooked a consideration which students of Science more especially need to have pointed out. Occupied as such are with established truths, and accustomed to regard things not already known as things to be hereafter discovered, they are liable to forget that information, however extensive it may become, can never satisfy inquiry. Positive knowledge does not, and never can, fill the whole region of possible thought. At the uttermost reach of discovery there arises, and must ever arise, the question What lies beyond? As it is impossible to think of a limit to space so as to exclude the idea of space lying outside that limit. so we cannot conceive of any explanation profound enough to exclude the question What is the explanation of that explanation? Regarding Science as a gradually increasing sphere, we may say that every addition to its surface does not bring it into wider contact with surrounding nescience. There must ever remain therefore two antithetical modes of mental action. Throughout all future time, as now, the human mind may occupy itself, not only with ascertained phenomena and their relations, but also with that unascertained something which phenomena and their relations imply. Hence if knowledge cannot monopolize consciousness if it must always continue possible for the mind to dwell upon that which transcends knowledge, then there can never cease to be a place for something of the nature of Religion; since Religion under all its forms is distinguished from everything else in this, that its subject matter passes the sphere of the intellect. Thus, however untenable may be the existing religious creeds, however gross the absurdities associated with them, however irrational the arguments set forth in their defence, we must not ignore the verity which in all likelihood lies hidden within them. the general probability that widely-spread beliefs are not absolutely baseless, is in this case enforced by a further probability due to the omnipresence of the beliefs. In the existence of a religious sentiment, whatever be its origin, we have a second evidence of great significance. And as in that nescience which must ever remain the antithesis to science, there is a sphere for the exercise of this sentiment, we find a third general fact of like implication. We may be sure, therefore, that religions, even though no one of them be actually true, are yet all adumbrations of a truth. 5. As, to the religious, it will seem absurd to set forth any justification for Religion, so, to the scientific, it will seem absurd to defend Science. Yet to do the last is certainly as needful as to do the first. If there exist some who, in contempt for its follies and disgust at its corruptions, have contracted towards Religion a repugnance which makes them overlook the fundamental truth contained in it; so, there are others offended to such a degree by the destructive criticisms men of science make on the religious tenets they hold essential, that they have acquired a strong prejudice against Science at large. they are not prepared with any reasons for their dislike. they have simply a remembrance of the rude shakes which Science has given to many of their cherished convictions, and a suspicion that it may eventually uproot all they regard as sacred; and hence it produces in them an inarticulate dread. What is Science? To see the absurdity of the prejudice against it, we need only remark that Science is simply a higher development of common knowledge; and that if Science is repudiated, all knowledge must be repudiated along with it. The extremest bigot will not suspect any harm in the observation that the Sun rises earlier and sets later in summer than in winter. but will rather consider such an observation as a useful aid in fulfilling the duties of life. Well, Astronomy is an organized body of kindred observations, made with greater nicety, extended to a larger number of objects, and so analyzed as to disclose the real arrangements of the heavens and to dispel our false conceptions of them. That iron will rust in water, that wood will burn, that long kept viands become putrid, the most timid sectarian will teach without alarm, as things useful to be known. But these are chemical truths: Chemistry is a systematized collection of such facts, ascertained with precision, and so classified and generalized as to enable us to say with certainty, concerning each simple or compound substance, what change will occur in it under given conditions. And thus is it with all the sciences. They severally germinate out of the experiences of daily life. insensibly as they grow they draw in remoter, more numerous, and more complex experiences; and among these, they ascertain laws of dependence like those which make up our knowledge of the most familiar objects. Nowhere is it possible to draw a line and say here Science begins. And as it is the function of common observation to serve for the guidance of conduct; so, too, is the guidance of conduct the office of the most recondite and abstract results of Science. Through the countless industrial processes and the various modes of locomotion it has given to us, Physics regulates more completely our social life than does his acquaintance with the properties of surrounding bodies regulate the life of the savage. All Science is prevision; and all prevision ultimately helps us in greater or less degree to achieve the good and avoid the bad. Thus being one in origin and function, the simplest forms of cognition and the most complex must be dealt with alike. We are bound in consistency to receive the widest knowledge our faculties can reach, or to reject along with it that narrow knowledge possessed by all. To ask the question which more immediately concerns our argument whether Science is substantially true? is much like asking whether the Sun gives light. And it is because they are conscious how undeniably valid are most of its propositions, that the theological party regard Science with so much secret alarm. They know that during the five thousand years of its growth, some of its larger divisions mathematics, physics, astronomy have been subject to the rigorous criticism of successive generations, and have notwithstanding become ever more firmly established. They know that, unlike many of their own doctrines, which were once universally received but have age by age been more widely doubted, the doctrines of Science, at first confined to a few scattered inquirers, have been slowly growing into general acceptance, and are now in great part admitted as beyond dispute. They know that scientific men throughout the world subject one another's results to searching examination; and that error is mercilessly exposed and rejected as soon as discovered. And, finally they know that still more conclusive evidence is furnished by the daily verification of scientific predictions, and by the never-ceasing triumphs of those arts which Science guides. To regard with alienation that which has such high credentials is a folly. Though in the tone which many of the scientific adopt towards them, the defenders of Religion may find some excuse for this alienation, yet the excuse is an insufficient one. On the side of Science, as on their own side, they must admit that short-comings in the advocates do not tell essentially against that which is advocated. Science must be judged by itself; and so judged, only the most perverted intellect can fail to see that it is worthy of all reverence. Be there or be there not any other revelation, we have a veritable revelation in Science a continuous disclosure of the established order of the Universe. This disclosure it is the duty of every one to verify as far as in him lies; and having verified, to receive with all humility. 6. Thus there must be right on both sides of this great controversy. Religion, everywhere present as a warp running through the weft of human history, expresses some eternal fact; while Science is an organized body of truths, ever growing, and ever being purified from errors. And if both have bases in the reality of things, then between them there must be a fundamental harmony. It is impossible that there should be two orders of truth in absolute and everlasting opposition. Only in pursuance of some Manichean hypothesis, which among ourselves no one dares openly avow, is such a supposition even conceivable. That Religion is divine and Science diabolical, is a proposition which, though implied in many a clerical declamation, not the most vehement fanatic can bring himself distinctly to assert. And whoever does not assert this, must admit that under their seeming antagonism lies hidden an entire agreement. Each side, therefore, has to recognize the claims of the other as representing truths which are not to be ignored. It behoves each to strive to understand the other, with the conviction that the other has something worthy to be understood; and with the conviction that when mutually recognized this something will be the basis of a reconciliation. How to find this something thus becomes the problem we should perseveringly try to solve. Not to reconcile them in any makeshift way, but to establish a real and permanent peace. The thing we have to seek out is that ultimate truth which both will avow with absolute sincerity with not the remotest mental reservation. There shall be no concession no yielding on either side of something that will by-and-by be reasserted; but the common ground on which they meet shall be one which each will maintain for itself. We have to discover some fundamental verity which Religion will assert, with all possible emphasis, in the absence of Science; and which Science, with all possible emphasis, will assert in the absence of Religion. We must look for a conception which combines the conclusions of both must see how Science and Religion express opposite sides of the same fact: the one its near or visible side, and the other its remote or invisible side. Already in the foregoing pages the method of seeking such a reconciliation has been vaguely shadowed forth. Before proceeding, however, it will be well to treat the question of method more definitely. To find that truth in which Religion and Science coalesce, we must know in what direction to look for it, and what kind of truth it is likely to be. 7. Only in some highly abstract proposition can Religion and Science find a common ground. Neither such dogmas as those of the trinitarian and unitarian, nor any such idea as that of propitiation, common though it may be to all religions, can serve as the desired basis of agreement; for Science cannot recognize beliefs like these: they lie beyond its sphere. Not only, as we have inferred, is the essential truth contained in Religion that most abstract element pervading all its forms, but, as we here see, this most abstract element is the only one in which Religion is likely to agree with Science. Similarly if we begin at the other end, and inquire what scientific truth can unite Science with Religion. Religion can take no cognizance of special scientific doctrines; any more than Science can take cognizance of special religious doctrines. The truth which Science asserts and Religion indorses cannot be one furnished by mathematics; nor can it be a physical truth; nor can it be a truth in chemistry. No generalization of the phenomena of space, of time, of matter, or of force, can become a Religious conception. Such a conception, if it anywhere exists in Science, must be more general than any of these must be one underlying all of them. Assuming, then, that since these two great realities are constituents of the same mind, and respond to different aspects of the same Universe, there must be a fundamental harmony between them, we see good reason to conclude that the most abstract truth contained in Religion and the most abstract truth contained in Science must be the one in which the two coalesce. The largest fact to be found within our mental range must be the one of which we are in search. Uniting these positive and negative poles of human thought, it must be the ultimate fact in our intelligence. 8. Before proceeding let me bespeak a little patience. The next three chapters, setting out from different points and converging to the same conclusion, will be unattractive. Students of philosophy will find in them much that is familiar and to most of those who are unacquainted with modern metaphysics, their reasonings may prove difficult to follow. Our argument, however, cannot dispense with these chapters, and the greatness of the question at issue justifies even a heavier tax on the reader's attention. Though it affects us little in a direct way, the view we arrive at must indirectly affect us all in our relations must determine Our conceptions of the Universe, of Life, of Human Nature must influence our ideas of right and wrong, and therefore modify our conduct. To reach that point of view from which the seeming discordance of Religion and Science disappears, and the two merge into one, must surely be worth an effort. Here ending preliminaries let us now address ourselves to this all- important inquiry. Chapter 2 Ultimate Religious Ideas 9. When, on the sea-shore, we note how the hulls of distant vessels are hidden below the horizon, and how, of still remoter vessels, only the uppermost sails are visible, we may conceive with tolerable clearness the slight curvature of that portion of the sea's surface which lies before us. But when we try to follow out in imagination this curved surface as it actually exists, slowly bending round until all its meridians meet in a point eight thousand miles below our feet, we find ourselves utterly baffled. We cannot conceive in its real form and magnitude even that small segment of our globe which extends a hundred miles on every side of us, much less the globe as a whole. The piece of rock on which we stand can be mentally represented with something like completeness: we are able to think of its top, its sides, and its under surface at the same time, or so nearly at the same time that they seem present in consciousness together; and so we can form what we call a conception of the rock. But to do the like with the Earth is impossible. If even to imagine the antipodes as at that distant place in space which it actually occupies, is beyond our power much more beyond our power must it be at the same time to imagine all other remote points on the Earth's surface as in their actual places. Yet we commonly speak as though we had an idea of the Earth as though we could think of it in the same way that we think of minor objects. What conception, then, do we form of it? the reader may ask. That its name calls up in us some state of consciousness is unquestionable; and if this state of consciousness is not a conception, properly so called, what is it? The answer seems to be this: We have learnt by indirect methods that the Earth is a sphere; we have formed models approximately representing its shape and the distribution of its parts; usually when the Earth is referred to, we either think of an indefinitely extended mass beneath our feet, or else, leaving out the actual Earth, we think of a body like a terrestrial globe; but when we seek to imagine the Earth as it really is, we join these two ideas as well as we can such perception as our eyes give us of the Earth's surface we couple with the conception of a sphere. And thus we form of the Earth not a conception properly so called, but only a symbolic conception.* <* Those who may have before met with this term, will perceive that it is here used in quite a different sense.> A large proportion of our conceptions, including all those of much generality, are of this order. Great magnitudes, great durations, great numbers, are none of them actually conceived, but are all of them conceived more or less symbolically; and so, too, are all those classes of objects of which we predicate some common fact. When mention is made of any individual man, a tolerably complete idea of him is formed. If the family he belongs to be spoken of, probably but a part of it will be represented in thought: under the necessity of attending to that which is said about the family, we realize in imagination only its most important or familiar members, and pass over the rest with a nascent consciousness which we know could, if requisite, be made complete. Should something be remarked of the class, say farmers, to which this family belongs, we neither enumerate in thought all the individuals contained in the class, nor believe that we could do so if required; but we are content with taking some few samples of it, and remembering that these could be indefinitely multiplied. Supposing the subject of which something is predicated be Englishmen, the answering state of consciousness is a still more inadequate representative. Yet more remote is the likeness of the thought to the thing, if reference be made to Europeans or to human beings. And when we come to propositions concerning the mammalia, or conceding the whole of the vertebrata, or concerning all organic beings, the unlikenesses of our conceptions to the realities become extreme. Throughout which series of instances we see that as the number of objects grouped together in thought increases, the concept, formed of a few typical samples joined with the notion of multiplicity, becomes more and more a mere symbol; not only because it gradually ceases to represent the size of the group, but also because, as the group grows more heterogeneous, the typical samples thought of are less like the average objects which the group contains. This formation of symbolic conceptions, which inevitably arises as we pass from small and concrete objects to large and to discrete ones, is mostly a useful, and indeed necessary, process. When, instead of things whose attributes can be tolerably well united in a single state of consciousness, we have to deal with things whose attributes are too vast or numerous to be so united, we must either drop in thought part of their attributes, or else not think of them at all either form a more or less symbolic conception, or no conception. We must predicate nothing of objects too great or too multitudinous to be mentally represented, or we must make our predications by the help of extremely inadequate representations of them. But while by doing this we are enabled to form general propositions, and so to reach general conclusions, we are perpetually led into danger, and very often into error. We mistake our symbolic conceptions for real ones; and so are betrayed into countless false inferences. Not only is it that in proportion as the concept we form of any thing, or class of things, misrepresents the reality, we are apt to be wrong in any assertion we make respecting the reality; but it is that we are led to suppose we have truly conceived many things which we have conceived only in this fictitious way; and then to confound with these some things which cannot be conceived in any way. How we fall into this error almost unavoidably it will be needful here to observe. From objects fully representable, to those of which we cannot form even approximate representations, there is an insensible transition. Between a pebble and the entire Earth a series of magnitudes might be introduced, severally differing from adjacent ones so slightly that it would be impossible to say at what point in the series our conceptions of them became inadequate. Similarly, there is a gradual progression from those groups of a few individuals which we can think of as groups with tolerable completeness, to those larger and larger groups of which we can form nothing like true ideas. Thus we pass from actual conceptions to symbolic ones by infinitesimal steps. Note next that we are led to deal with our symbolic conceptions as though they were actual ones, not only because we cannot clearly separate the two, but also because, in most cases, the first serve our purposes nearly or quite as well as the last are simply the abbreviated signs we substitute for those more elaborate signs which are our equivalents for real objects. Those imperfect representations of ordinary things which we make in thinking, we know can be developed into adequate ones if needful. Those concepts of larger magnitudes and more extensive classes which we cannot make adequate, we still find can be verified by some indirect process of measurement or enumeration. And even in the case of such an utterly inconceivable object as the Solar System, we yet, through the fulfilment of predictions founded on our symbolic conception of it, gain the conviction that this stands for an actual existence, and, in a sense, truly expresses certain of its constituent relations. So that having learnt by long experience that our symbolic conceptions can, if needful, be verified, we are led to accept them without verification. Thus we open the door to some which profess to stand for known things, but which really stand for things that cannot be known in any way. The implication is clear. When our symbolic conceptions are such that no cumulative or indirect processes of thought can enable us to ascertain that there are corresponding actualities, nor any fulfilled predictions be assigned in justification of them, then they are altogether vicious and illusive, and in no way distinguishable from pure fictions. 10. And now to consider the bearings of this general truth on our immediate topic Ultimate Religious Ideas. To the primitive man sometimes happen things which are out of the ordinary course-diseases, storms, earth-quakes, echoes, eclipses. From dreams arises the idea of a wandering double; whence follows the belief that the double, departing permanently at death, is then a ghost. Ghosts thus become assignable causes for strange occurrences. The greater ghosts are presently supposed to have extended spheres of action. As men grow intelligent the conceptions of these minor invisible agencies merge into the conception of a universal invisible agency; and there result hypotheses concerning the origin, not of special incidents only, but of things in general. A critical examination, however will prove not only that no current hypothesis is tenable, but also that no tenable hypothesis can be framed. 11. Respecting the origin of the Universe three verbally intelligible suppositions may be made. We may assert that it is self-existent; or that it is self-created; or that it is created by an external agency. Which of these suppositions is most credible it is not needful here to inquire. The deeper question, into which this finally merges, is, whether any one of them is even conceivable in the true sense of the word. Let us successively test them. When we speak of a man as self-supporting, of an apparatus as self- acting, or of a tree as self-developed, our expressions, however inexact, stand for things that can be figured in thought with tolerable completeness. Our conception of the self-development of a tree is doubtless symbolic. But though we cannot really represent in consciousness the. entire series of complex changes through which the tree passes, yet we can thus represent the leading traits of the series; and general experience teaches us that by long continued observation we could gain the power of more fully representing it. That is, we know that our symbolic conception of self-development can be expanded into something like a real conception; and that it expresses, however rudely, an actual process. But when we speak of self-existence and, helped by the above analogies, form some vague symbolic conception of it, we delude ourselves in supposing that this symbolic conception is of the same order as the others. On joining the word self to the word existence, the force of association makes us believe we have a thought like that suggested by the compound word self-acting. An endeavour to expand this symbolic conception, however, will undeceive us. In the first place, it is clear that by self-existence we especially mean an existence independent of any other not produced by any other: the assertion of self-existence is an indirect denial of creation. In thus excluding the idea of any antecedent cause, we necessarily exclude the idea of a beginning. for to admit that there was a time when the existence had not commenced, is to admit that its commencement was determined by something, or was caused, which is a contradiction. Self-existence, therefore, necessarily means existence without a beginning; and to form a conception of self-existence is to form a conception of existence without a beginning. Now by no mental effort can we do this. To conceive existence through infinite past-time, implies the conception of infinite past-time, which is an impossibility. To this let us add that even were self-existence conceivable, it would not be an explanation of the Universe. No one will say that the existence of an object at the present moment is made easier to understand by the discovery that it existed an hour ago, or a day ago, or a year ago; and if its existence now is not made more comprehensible by knowledge of its existence during some previous finite period, then no knowledge of it during many such finite periods, even could we extend them to an infinite period, would make it more comprehensible. Thus the Atheistic theory is not only absolutely unthinkable, but, even were it thinkable, would not be a solution. The assertion that the Universe is self-existent does not really carry us a step beyond the cognition of its present existence; and so leaves us with a mere re-statement of the mystery. The hypothesis of self-creation, which practically amounts to what is called Pantheism, is similarly incapable of being represented in thought. Certain phenomena, such as the precipitation of invisible vapour into cloud, aid us in forming a symbolic conception of a self-evolved Universe; and there are not wanting indications in the Heavens, and on the Earth, which help us in giving to this conception some distinctness. But while the succession of phases through which the visible Universe has passed in reaching its present form, may perhaps be comprehended as in a sense self- determined; yet the impossibility of expanding our symbolic conception of self-creation into a real conception, remains as complete as ever. Really to conceive self-creation, is to conceive potential existence passing into actual existence by some inherent necessity, which we cannot. We cannot form any idea of a potential existence of the Universe, as distinguished from its actual existence. If represented in thought at all, potential existence must be represented as something, that is, as an actual existence: to suppose that it can be represented as nothing involves two absurdities that nothing is more than a negation, and can be positively represented in thought, and that one nothing is distinguished from all other nothings by its power to develop into something. Nor is this all. We have no state of consciousness answering to the words an inherent necessity by which potential existence became actual existence. To render them into thought, existence, having for an indefinite period remained in one form, must be conceived as passing without any external impulse into another form; and this involves the idea of a change without a cause a thing of which no idea is possible. Thus the terms of this hypothesis do not stand for real thoughts, but merely suggest the vaguest symbols not admitting of any interpretation. Moreover, even were potential existence conceivable as a different thing from actual existence, and could the transition from the one to the other be mentally realized as self-determined, we should still be no forwarder: the problem would simply be removed a step back. For whence the potential existence? This would just as much require accounting for as actual existence, and just the same difficulties would meet us. The self-existence of a potential Universe is no more conceivable than the self-existence of the actual Universe. The self-creation of a potential Universe would involve over again the difficulties just stated would imply behind this potential universe a more remote potentiality, and so on in an infinite series, leaving us at last no forwarder than at first. While to assign an externa1 agency as its origin, would be to introduce the notion of a potential Universe for no purpose whatever. There remains the commonly received or theistic hypothesis creation by external agency. Alike in the rudest creeds and in the cosmogony long current among ourselves, it is assumed that the Heavens and the Earth were made somewhat after the manner in which a workman makes a piece of furniture. And this is the assumption not only of theologians but of most philosophers. Equally in the writings of Plato and in those of not a few living men of science, we find it assumed that there is an analogy between the process of creation and the process of manufacture. Now not only is this conception one which cannot by any cumulative process of thought, or the fulfilment of predictions based on it, be shown to answer to anything actual; but it cannot be mentally realized, even when all its assumptions are granted. Though the proceedings of a human artificer may vaguely symbolize a method after which the Universe might be shaped, yet imagination of this method does not help us to solve the ultimate problem; namely, the origin of the materials of which the Universe consists. The artizan does not make the iron, wood, or stone, he uses, but merely fashions and combines them. If we suppose suns, and planets, and satellites, and all they contain to have been similarly formed by a "Great Artificer," we suppose merely that certain pre-existing elements were thus put into their present arrangement. But whence the pre-existing elements? The production of matter out of nothing is the real mystery which neither this simile nor any other enables us to conceive; and a simile which does not enable us to conceive this may as well be dispensed with. Still more manifest becomes the insufficiency of this theory of things, when we turn from material objects to that which contains them when instead of matter we contemplate space. Did there exist nothing but an immeasurable void, explanation would be needed as much as it is now. There would still arise the question how came it so? If the theory of creation by external agency were an adequate one, it would supply an answer; and its answer would be space was made in the same manner that matter was made. But the impossibility of conceiving this is so manifest that no one dares to assert it. For if space was created it must have been previously non-existent. The non-existence of space cannot, however, by any mental effort be imagined. And if the non-existence of space is absolutely inconceivable, then, necessarily, its creation is absolutely inconceivable. Lastly, even supposing that the genesis of the Universe could really be represented in thought as due to an external agency, the mystery would be as great as ever; for there would still arise the question how came there to be an external agency? To account for this only the same three hypotheses are possible self-existence, self-creation, and creation by external agency. Of these the last is useless: it commits us to an infinite series of such agencies, and even then leaves us where we were. By the second we are led into the same predicament; since, as already shown, self-creation implies an infinite series of potential existences. We are obliged, therefore, to fall back on the first, which is the one commonly accepted and commonly supposed to be satisfactory. Those who cannot conceive a self-existent Universe, and therefore assume a creator as the source of the Universe, take for granted that they can conceive a self-existent Creator. The mystery which they recognize in this great fact surrounding them on every side, they transfer to an alleged source of this great fact, and then suppose that they have solved the mystery. But they delude themselves. As was proved at the outset of the argument, self- existence is inconceivable; and this holds true whatever be the nature of the object of which it is predicated. Whoever agrees that the atheistic hypothesis is untenable because it involves the impossible idea of self-existence, must perforce admit that the theistic hypothesis is untenable if it contains the same impossible idea. Thus these three different suppositions, verbally intelligible though they are, and severally seeming to their respective adherents quite rational, turn out, when critically examined, to be literally unthinkable. It is not a question of probability, or credibility, but of conceivability. Experiment proves that the elements of these hypotheses cannot even be put together in consciousness; and we can entertain them only as we entertain such pseud-ideas as a square fluid and a moral substance only by abstaining from the endeavour to render them into actual thoughts. Or, reverting to our original mode of statement, we may say that they severally involve symbolic conceptions of the illegitimate and illusive kind. Differing so widely as they seem to do, the atheistic, the pantheistic, and the theistic hypotheses contain the same ultimate element. It is impossible to avoid making the assumption of self-existence somewhere; and whether that assumption be made nakedly or under complicated disguises, it is equally vicious, equally unthinkable. Be it a fragment of matter, or some fancied potential form of matter, or some more remote and still less imaginable mode of being, our conception of its self-existence can be framed only by joining with it the notion of unlimited duration through past time. And as unlimited duration is inconceivable, all those formal ideas into which it enters are inconceivable; and indeed, if such an expression is allowable, are the more inconceivable in proportion as the other elements of the ideas are indefinite. So that in fact, impossible as it is to think of the actual Universe as self-existing, we do but multiply impossibilities of thought by every attempt we make to explain its existence. 12. If from the origin of the Universe we turn to its nature, the like insurmountable difficulties rise up before us on all sides or rather, the same difficulties under new aspects. We find ourselves obliged to make certain assumptions; and yet we find these assumptions cannot be represented in thought. When we inquire what is the meaning of the effects produced on our senses when we ask how there come to be in our consciousness impressions of sounds, of colours, of tastes, and of those various attributes we ascribe to bodies, we are compelled to regard them as the effects of some cause. We may stop short in the belief that this cause is what we call matter. Or we may conclude, as some do, that matter is only a certain mode of manifestation of spirit, which is therefore the true cause. Or, regarding matter and spirit as proximate agencies, we may ascribe the changes wrought in our consciousness to immediate divine power. But be the cause we assign what it may, we are obliged to suppose some cause. And we are obliged not only to suppose some cause, but also a first cause. The matter, or spirit or other agent producing these impressions on us, must either be the first cause of them or not. If it is the first cause the conclusion is reached. If it is not the first cause, then by implication there must be a cause behind it, which thus becomes the real cause of the effect. Manifestly however complicated the assumptions, the same conclusion must be reached. We cannot ask how the changes in our consciousness are caused, without inevitably committing ourselves to the hypothesis of a First Cause. But now if we ask what is the nature of this First Cause, we are driven by an inexorable logic to certain further conclusions. Is the First Cause finite or infinite? If we say finite we involve ourselves in a dilemma. To think of the First Cause as finite, is to think of it as limited. To think of it as limited implies a consciousness of something beyond its limits: it is impossible to conceive a thing as bounded without assuming a region surrounding its boundaries. What now must we say of this region? If the First Cause is limited, and there consequently lies something outside of it, this something must have no First Cause must be uncaused. But if we admit that there can be something uncaused, there is no reason to assume a cause for anything. If beyond that finite region over which the First Cause extends, there lies a region, which we are compelled to regard as infinite, over which it does not extend if we admit that there is an infinite uncaused surrounding the finite caused; we tacitly abandon the hypothesis of causation altogether. Thus it is impossible to consider the First Cause as finite. But if it cannot be finite it must be infinite. Another inference conceding the First Cause is equally necessary. It must be independent. If it is dependent it cannot be the First Cause; for that must be the First Cause on which it depends. It is not enough to say that it is partially independent; since this implies some necessity which determines its partial dependence, and this necessity, be it what it may, must be a higher cause, or the true First Cause, which is a contradiction. But to think of the First Cause as totally independent, is to think of it as that which exists in the absence of all other existence; seeing that if the presence of any other existence is necessary, it must be partially dependent on that other existence, and so cannot be the First Cause. Not only however must the First Cause be a form of being which has no necessary relation to any other form of being, but it can have no necessary relation within itself. There can be nothing in it which determines change, and yet nothing which prevents change. For if it contains something which imposes such necessities or restraints, this something must be a cause higher than the First Cause, which is absurd. Thus the First Cause must be in every sense perfect, complete, total: including within itself all power and transcending all law. Or to use the established word, it must be Absolute. Certain conclusions respecting the nature of the Universe, thus seem unavoidable. In our search after causes, we discover no resting place until we arrive at a First Cause; and we have no alternative but to regard this First Cause as Infinite and Absolute. These are inferences forced on us by arguments from which there appears no escape. Nevertheless neither arguments nor inferences have more than nominal values. It might easily be shown that the materials of which the arguments are built, equally with the conclusions based on them, are merely symbolic conceptions of the illegitimate order. Instead, however, of repeating the disproof used above, it will be well to pursue another method; showing the fallacy of these conclusions by disclosing their mutual contradictions. Here I cannot do better than avail myself of the demonstration which Mr. Mansel, carrying out in detail the doctrine of Sir William Hamilton, has given in his Limits of Religious Thought. And I gladly do this, not only because his mode of presentation cannot be improved, but also because, writing as he does in defence of the current Theology, his reasonings will be the more acceptable to the majority of readers. 13. Having given preliminary definitions of the First Cause, of the Infinite, and of the Absolute, Mr. Mansel says: "But these three conceptions, the Cause, the Absolute, the Infinite, all equally indispensable, do they not imply contradiction to each other, when viewed in conjunction, as attributes of one and the same Being? A Cause cannot, as such, be absolute: the Absolute cannot, as such, be a cause. The cause, as such, exists only in relation to its effect: the cause is a cause of the effect; the effect is an effect of the cause. On the other hand, the conception of the Absolute implies a possible existence out of all relation. We attempt to escape from this apparent contradiction, by introducing the idea of succession in time. The Absolute exists first by itself, and afterwards becomes a Cause. But here we are checked by the third conception, that of the Infinite. How can the Infinite become that which it was not from the first? If Causation is a possible mode of existence, that which exists without causing is not infinite; that which becomes a cause has passed beyond its former limits. * * * "Supposing the Absolute to become a cause, it will follow that it operates by means of freewill and consciousness. For a necessary cause cannot be conceived as absolute and infinite. If necessitated by something beyond itself, it is thereby limited by a superior power; and if necessitated by itself, it has in its own nature a necessary relation to its effect. The act of causation must therefore be voluntary; and volition is only possible in a conscious being. But consciousness again is only conceivable as a relation. There must be a conscious subject, and an object of which he is conscious. The subject is a subject to the object; the object is an object to the subject; and neither can exist by itself as the absolute. This difficulty, again, may be for the moment evaded, by distinguishing between the absolute as related to another and the absolute as related to itself. The Absolute, it may be said, may possibly be conscious, provided it is only conscious of itself. But this alternative is, in ultimate analysis, no less self-destructive than the other. For the object of consciousness, whether a mode of the Subject's existence or not, is either created in and by the act of consciousness, or has an existence independent of it. In the former case, the object depends upon the subject, and the subject alone is the true absolute. In the latter case, the subject depends upon the object, and the object alone is the true absolute. Or if we attempt a third hypothesis, and maintain that each exists independently of the other, we have no absolute at all, but only a pair of relatives; for coexistence, whether in consciousness or not, is itself a relation. "The corollary from this reasoning is obvious. Not only is the Absolute, as conceived, incapable of a necessary relation to anything else but it is also incapable of containing, by the constitution of its own nature, an essential relation within itself; as a whole, for instance, composed of parts, or as a substance consisting of attributes, or as a conscious subject in antithesis to an object. For if there is in the absolute any principle of unity, distinct from the mere accumulation of parts or attributes, this principle alone is the true absolute. If, on the other hand, there is no such principle, then there is no absolute at all, but only a plurality of relatives. The almost unanimous voice of philosophy, in pronouncing that the absolute is both one and simple, must be accepted as the voice of reason also, so far as reason has any voice in the matter. But this absolute unity, as indifferent and containing no attributes, can neither be distinguished from the multiplicity of finite beings by any characteristic feature, nor be identified with them in their multiplicity. Thus we are landed in an inextricable dilemma. The Absolute cannot be conceived as conscious, neither can it be conceived as unconscious; it cannot be conceived as complex, neither can it be conceived as simple: it cannot be conceived by difference, neither can it be conceived by the absence of difference: it cannot be identified with the universe, neither can it be distinguished from it. The One and the Many, regarded as the beginning of existence, are thus alike incomprehensible. "The fundamental conceptions of Rational Theology being thus self- destructive, we may naturally expect to find the same antagonism manifested in their special applications. * * * How, for example. Can Infinite Power be able to do all things, and yet Infinite Goodness be unable to do evil? How can Infinite Justice exact the utmost penalty for every sin, and yet Infinite Mercy pardon the sinner? How can Infinite Wisdom know all that is to come, and yet Infinite Freedom be at liberty to do or to forbear? How is the existence of Evil compatible with that of an infinitely perfect Being; for if he wills it, he is not infinitely good; and if he will it not, his will is thwarted and his sphere of action limited? * * * "Let us, however, suppose for an instant that these difficulties are surmounted, and the existence of the Absolute securely established on the testimony of reason. Still we have not succeeded in reconciling this idea with that of a Cause: we have done nothing towards explaining how the absolute can give rise to the relative, the infinite to the finite. If the condition of causal activity is a higher state than that of quiescence, the Absolute, whether acting voluntarily or involuntarily, has passed from a condition of comparative imperfection to one of comparative perfection; and therefore was not originally perfect. If the state of activity is an inferior state to that of quiescence, the Absolute, in becoming a cause, has lost its original perfection. There remains only the supposition that the two states are equal, and the act of creation one of complete indifference. But this supposition annihilates the unity of the absolute, or it annihilates itself. If the act of creation is real, and yet indifferent, we must admit the possibility of two conceptions of the absolute, the one as productive, the other as non-productive. If the act is not real, the supposition itself vanishes. * * * "Again, how can the relative be conceived as coming into being? If it is a distinct reality from the absolute, it must be conceived as passing from non-existence into existence. But to conceive an object as non-existent, is again a self-contradiction; for that which is conceived exists, as an object of thought, in and by that conception. We may abstain from thinking of an object at all; but, if we think of it, we cannot but think of it as existing. It is possible at one time not to think of an object at all, and at another to think of it as already in being; but to think of it in the act of becoming, in the progress from not being into being, is to think that which, in the very thought, annihilates itself. * * * "To sum up briefly this portion of my argument. The conception of the Absolute and Infinite, from whatever side we view it, appears encompassed with contradictions. There is a contradiction in supposing such an object to exist, whether alone or in conjunction with others; and there is a contradiction in supposing it not to exist. There is a contradiction in conceiving it as one; and there is a contradiction in conceiving it as many. There is a contradiction in conceiving it as personal; and there is a contradiction in conceiving it as impersonal. It cannot, without contradiction, be represented as active; nor, without equal contradiction, be represented as inactive. It cannot be conceived as the sum of all existence; nor yet can it be conceived as a part only of that sum." 14. And now what is the bearing of these results on the question before us? Our examination of Ultimate Religious Ideas has been carried on with the view of making manifest some fundamental verity contained in them. Thus far, however, we have arrived at negative conclusions only. Passing over the consideration of credibility, and confining ourselves to that of conceivability we have seen that Atheism, Pantheism, and Theism, when rigorously analyzed, severally prove to be wholly unthinkable. Instead of disclosing a fundamental verity existing in each, our inquiry seems rather to have shown that there is no fundamental verity contained in any. To carry away this conclusion, however, would be a fatal error, as we shall shortly see. Leaving out the accompanying code of conduct, which is a supplementary growth, a religious creed is definable as a theory of original causation. By the lowest savages the genesis of things is not inquired about: only strange appearances and actions raise the question of agency. But be it in the primitive Ghost-theory, which assumes a human personality behind each unusual phenomenon; be it in Polytheism, in which such personalities are partially generalized; be it in Monotheism, in which they are wholly generalized; or be it in Pantheism, in which the generalized personality becomes one with the phenomena; we equally find an hypothesis which is supposed to render the Universe comprehensible. Nay, even that which is regarded as the negation of all Religion even positive Atheism comes within the definition; for it, too, in asserting the self-existence of Space, Matter and Motion, propounds a theory from which it holds the facts to be deducible. Now every theory tacitly asserts two things: first, that there is something to be explained; second, that such and such is the explanation. Hence, however widely different speculators disagree in the solutions they give of the same problem, yet by implication they agree that there is a problem to be solved. Here then is an element which all creeds have in common. Religions diametrically opposed in their overt dogmas, are perfectly at one in the tacit conviction that the existence of the world with all it contains and all which surrounds it, is a mystery calling for interpretation. Thus we come within sight of that which we seek. In the last chapter, reasons were given for inferring that human beliefs in general, and especially the perennial ones, contain, under whatever disguises of error, some soul of truth; and here we have arrived at a truth underlying even the rudest beliefs. We saw, further, that this soul of truth is most likely some constituent common to conflicting opinions of the same order; and here we have a constituent contained by all religions. It was pointed out that this soul of truth would almost certainly be more abstract than any of the creeds involving it; and the truth above reached is one exceeding in abstractness the most abstract religious doctrines. In every respect, therefore, our conclusion answers to the requirements. That this is the vital element in all religions is further shown by the fact that it is the element which not only survives every change but grows more distinct the more highly the religion is developed. Aboriginal creeds, pervaded by thoughts of personal agencies which are usually unseen, conceive these agencies under perfectly concrete and ordinary forms-class them with the visible agencies of men and animals; and so hide a vague perception of mystery in disguises as unmysterious as possible. Polytheistic conceptions in their advanced phases, represent the presiding personalities in idealized shapes, working in subtle ways, and communicating with men by omens or through inspired persons; that is, the ultimate causes of things are regarded as less familiar and comprehensible. The growth of a Monotheistic faith, accompanied as it is by lapse of those beliefs in which the divine nature is assimilated to the human in all its lower propensities, shows us a further step in the same direction; and however imperfectly this higher faith is at first held, we yet see in altars "to the unknown and unknowable God," and in the worship of a God who cannot by any searching be found out, that there is a clearer recognition of the inscrutableness of creation. Further developments of theology, ending in such assertions as that "a God understood would be no God at all," and "to think that God is, as we can think him to be, is blasphemy," exhibit this recognition still more distinctly. It pervades all the cultivated theology of the present day. So that while other elements of religious creeds one by one drop away, this remains and grows ever more manifest, and thus is shown to be the essential element. Here, then, is a truth in which religions in general agree with one another, and with a philosophy antagonistic to their special dogmas. If Religion and Science are to be reconciled, the basis of reconciliation must be this deepest, widest, and most certain of all facts-that the Power which the Universe manifests to us is inscrutable. Chapter 3 Ultimate Scientific Ideas 15. What are Space and Time? Two hypotheses are current respecting them: the one that they are objective, the other that they are subjective. Let us see what becomes of these hypotheses under analysis. To say that Space and Time exist objectively, is to say that they are entities. The assertion that they are non-entities is self- destructive: non-entities are non-existences; and to allege that non-existences exist objectively is a contradiction in terms. Moreover, to deny that Space and Time are things, and so by implication to call them nothings, involves the absurdity that there are two kinds of nothing. Neither can they be regarded as attributes of some entity. Not only is it impossible to conceive any entity of which they are attributes, but we cannot think of them as disappearing, even if everything else disappeared; whereas attributes necessarily disappear along with the entities they belong to. Thus as Space and Time can be neither non-entities nor the attributes of entities, we are compelled to consider them as entities. But while, on the hypothesis of their objectivity, Space and Time must be classed as things, we find that to represent them in thought as things is impossible. To be conceived at all, a thing must be conceived as having attributes. We can distinguish something from nothing, only by the power which the something has to act on our consciousness. The effects it mediately or immediately produces on our consciousness we attribute to it, and call its attributes; and the absence of these attributes is the absence of the terms in which the something is conceived, and involves the absence of a conception. What, now, are the attributes of Space? The only one which it is possible to think of as belonging to it is that of extension, and to credit it with this is to identify object and attribute. For extension and Space are convertible terms: by extension, as we ascribe it to surrounding objects, we mean occupancy of Space; and thus to say that Space is extended, is to say that Space occupies Space. How we are similarly unable to assign any attribute to Time, scarcely needs pointing out. Nor are Time and Space unthinkable as entities only from the absence of attributes. There is another peculiarity, familiar to most people, which equally excludes them from the category. All entities actually known as such, are limited; and even if we suppose ourselves either to know or to be able to conceive some unlimited entity, we necessarily in so classing it separate it from the class of limited entities. But of Space and Time we cannot assert either limitation or the absence of limitation. We find ourselves unable to form any mental image of unbounded Space; and yet are unable to imagine bounds beyond which there is no Space. Similarly at the other extreme: it is impossible to think of a limit to the divisibility of Space; yet equally impossible to think of its infinite divisibility. And, without stating them, it will be seen that we labour under like impotences in respect to Time. Thus we cannot conceive Space and Time as entities, and are equally disabled from conceiving them as either the attributes of entities or as non-entities. We are compelled to think of them as existing, and yet cannot bring them within those conditions under which existences are represented in thought. Shall we then take refuge in the Kantian doctrine? Shall we say that Space and Time are forms of the intellect, "a priori laws or conditions of the conscious mind?" To do this is to escape from great difficulties by rushing into greater. The proposition with which Kant's philosophy sets out, verbally intelligible though it is, cannot by any effort be rendered into thought cannot be interpreted into an idea properly so called, but stands merely for a pseud-idea. In the first place, to assert that Space and Time are subjective conditions is, by implication, to assert that they are not objective realities: if the Space and Time present to our minds belong to the ego, then of necessity they do not belong to the non- ego. Now it is impossible to think this. The very fact on which Kant bases his hypothesis namely that our consciousness of Space and Time cannot be suppressed testifies as much; for that consciousness of Space and Time which we cannot rid ourselves of, is the consciousness of them as existing objectively. It is useless to reply that such an inability must inevitably result if they are subjective forms. The question here is What does consciousness directly testify? And the direct testimony of consciousness is, that Time and Space are not within the mind but without the mind; and so absolutely independent that we cannot conceive them to become non- existent even supposing the mind to become non-existent. Besides being positively unthinkable in what it tacitly denies, the theory of Kant is equally unthinkable in what it openly affirms. It is not simply that we cannot combine the thought of Space with the thought of our own personality, and contemplate the one as a property of the other though our inability to do this would prove the inconceivableness of the hypothesis but it is that the hypothesis carries in itself the proof of its own inconceivableness. For if Space and Time are forms of intuition, they can never be intuited; since it is impossible for anything to be at once the form of intuition and the matter of intuition. That Space and Time are objects of consciousness, Kant emphatically asserts by saying that it is impossible to suppress the consciousness of them. How then, if they are objects of consciousness, can they at the same time be conditions of consciousness? If Space and Time are the conditions under which we think, then when we think of Space and Time themselves, our thoughts must be unconditioned; and if there can thus be unconditioned thoughts, what becomes of the theory? It results, therefore, that Space and Time are wholly incomprehensible. The immediate knowledge which we seem to have of them proves, when examined, to be total ignorance. While our belief in their objective reality is insurmountable, we are unable to give any rational account of it. And to posit the alternative belief (possible to state but impossible to realize) is merely to multiply irrationalities. 16. Were it not for the necessities of the argument, it would be inexcusable to occupy the reader's attention with the threadbare, and yet unended, controversy respecting the divisibility of matter. Matter is either infinitely divisible or it is not: no third possibility can be named. Which of the alternatives shall we accept? If we say that Matter is infinitely divisible, we commit ourselves to a supposition not realizable in thought. We can bisect and re- bisect a body, and continually repeating the act until we reduce its parts to a size no longer physically divisible, may then mentally continue the process. To do this, however, is not really to conceive the infinite divisibility of matter, but to form a symbolic conception not admitting of expansion into a real one, and not admitting of other verification. Really to conceive the infinite divisibility of matter, is mentally to follow out the divisions to infinity. and to do this would require infinite time. On the other hand, to assert that matter is not infinitely divisible, is to assert that it is reducible to parts which no power can divide; and this verbal supposition can no more be represented in thought than the other. For each of such ultimate parts, did they exist, must have an under and an upper surface, a right and a left side, like any larger fragment. Now it is impossible to imagine its sides so near that no plane of section can be conceived between them; and however great be the assumed force of cohesion, it is impossible to shut out the idea of a greater force capable of overcoming it. So that to human intelligence the one hypothesis is no more acceptable than the other; and yet the conclusion that one or other must agree with the fact, seems to human intelligence unavoidable. Again, let us ask whether substance has anything like that extended solidity which it presents to our consciousness. The portion of space occupied by a piece of metal, seems to eyes and fingers perfectly filled: we perceive a homogeneous, resisting mass, without any breach of continuity. Shall we then say that Matter is actually as solid as it appears? Shall we say that whether it consists of an infinitely divisible element or of units which cannot be further divided, its parts are everywhere in actual contact? To assert as much entangles us in insuperable difficulties. Were Matter thus absolutely solid it would be what it is not absolutely incompressible; since compressibility, implying the nearer approach of constituent parts, is not thinkable unless there is unoccupied space among the parts. The supposition that Matter is absolutely solid being untenable, there presents itself the Newtonian supposition, that it consists of solid atoms not in contact but acting on one another by attractive and repulsive forces, varying with the distances. To assume this, however, merely shifts the difficulty. For granting that Matter as we perceive it, is made up of dense extended units attracting and repelling, the question still arises What is the constitution of these units? We must regard each of them as a small piece of matter. Looked at through a mental microscope, each becomes a mass such as we have just been contemplating. Just the same inquiries may be made respecting the parts of which each atom consists; while just the same difficulties stand in the way of every answer. Even were the hypothetical atom assumed to consist of still minuter ones, the difficulty would reappear at the next step; and so on perpetually. Boscovich's conception yet remains to us. Seeing that Matter could not, as Leibnitz suggested, be composed of unextended monads (since the juxtaposition of an infinity of points having no extension could not produce that extension which matter possesses), and perceiving objections to the view entertained by Newton, Boscovich proposed an intermediate theory. This theory is that the constituents of Matter are centres of force points without dimensions which attract and repel one another in such wise as to be kept at specific distances apart. And he argues, mathematically, that the forces possessed by such centres might so vary with the distances that, under given conditions, the centres would remain in stable equilibrium with definite interspaces; and yet, under other conditions, would maintain larger or smaller interspaces. This speculation, however, escapes all the inconceivabilities above indicated by merging them in the one inconceivability with which it sets cut. A centre of force absolutely without extension is unthinkable. The idea of resistance cannot be separated in thought from the idea of something which offers resistance, and this something must be thought of as occuppying space. To suppose that central forces can reside in points having positions only, with nothing to mark their positions points in no respect distinguishable from surrounding points which are not centres of force is beyond human power. But though the conception of Matter as consisting of dense indivisible units is symbolic, and cannot by any effort be thought out, it may yet be supposed to find indirect verification in the truths of chemistry. These, it is argued, necessitate the belief that Matter consists of particles of specific weights, and therefore of specific sizes. The law of definite proportions seems impossible on any other condition than the existence of ultimate atoms; and though the combining weights of the respective elements are termed by chemists their "equivalents," for the purpose of avoiding a questionable assumption, we are unable to think of the combination of such definite weights, without supposing it to take place between definite molecules. Thus it would appear that the Newtonian view is at any rate preferable to that of Boscovich. A disciple of Boscovich, however, may reply that his master's theory is involved in that of Newton, and cannot indeed be escaped. "What holds together the parts of these ultimate atoms?" he may ask. "A cohesive force," his opponent must answer. "And what," he may continue, "holds together the parts of any fragments into which, by sufficient force, an ultimate atom might be broken?" Again the answer must be a cohesive force. "And what," he may still ask, "if the ultimate atom were reduced to parts as small in proportion to it, as it is in proportion to a tangible mass of matter what must give each part the ability to sustain itself?" Still there is no answer but a cohesive force. Carry on the mental process and we can find no limit until we arrive at the symbolic conception of centres of force without any extension. Matter then, in its ultimate nature, is as absolutely incomprehensible as Space and Time. Whatever supposition we frame leaves us nothing but a choice between opposite absurdities.* <* To discuss Lord Kelvin's hypothesis of vortex-atoms, from the scientific point of view, is beyond my ability. From the philosophical point of view, however I may say that since it postulates a homogeneous medium which is strictly continuous (non- molecular), which is incompressible, which is a perfect fluid in the sense of having no viscosity, and which has inertia, it sets out with what appears to me an inconceivability. A fluid which has inertia, implying mass, and which is yet absolutely frictionless. so that its parts move among one another without any loss of motion, cannot be truly represented in consciousness. Even were it otherwise, the hypothesis is held by Prof. Clerk Maxwell to be untenable (see art. "Atom," Ency. Brit.).> 17. A body impelled by the hand is perceived to move, and to move in a definite direction; doubt about its motion seems impossible. Yet we not only may be, but usually are, quite wrong in both these judgments. Here, for instance, is a ship which we will suppose to be anchored at the equator with her head to the West. When the captain walks from stem to stern, in what direction does he move? East is the obvious answer an answer which for the moment may pass without criticism. But now the anchor is heaved, and the vessel sails to the West with a velocity equal to that at which the captain walks. In what direction does he now move when he goes from stem to stern? You cannot say East, for the vessel is carrying him as fast towards the West as he walks to the East; and you cannot say West for the converse reason In respect to things outside the vessel he is stationary, though to all on board he seems to be moving. But now are we quite sure of this conclusion? Is he really stationary? On taking into account the Earth's motion round its axis, we find that he is travelling at the rate of 1000 miles per hour to the East; so that neither the perception of one who looks at him, nor the inference of one who allows for the ship's motion, is anything like right. Nor indeed, on further consideration, do we find this revised conclusion to be much better. For we have not allowed for the Earth's motion in its orbit. This being some 68,000 miles per hour, it follows that, assuming the time to be midday, he is moving, not at the rate of 1000 miles per hour to the East, but at the rate of 67,000 miles per hour to the East. Nay not even now have we discovered the true rate and the true direction of his movement. With the Earth's progress in its orbit, we have to join that of the whole Solar system towards the constellation Hercules. When we do this, we perceive that he is moving neither East nor West, but in a line inclined to the plane of the Ecliptic, and at a velocity greater or less (according to the time of the year) than that above named. And were the constitution of our Sidereal System fully known, we should probably discover the direction and rate of his actual movement to differ considerably even from these. Thus we are taught that what we are conscious of is not the real motion of any object, either in its rate or direction, but merely its motion as measured from an assigned position either our own or some other. Yet in this very process of concluding that the motions we perceive are not the real motions, we tacitly assume that there are real motions. We take for granted that there is an absolute course and an absolute velocity and we find it impossible to rid ourselves of this idea. Nevertheless, absolute motion cannot even be imagined, much less known. Apart from those marks in space which we habitually associate with it, motion is unthinkable. For motion is change of place; but in space without marks, change of place is inconceivable, because place itself is inconceivable. Place can be conceived only by reference to other places; and in the absence of objects dispersed through space, a place could be conceived only in relation to the limits of space; whence it follows that in unlimited space, place cannot be conceived all places must be equidistant from boundaries which do not exist. Thus while obliged to think that there is an absolute motion, we find absolute motion cannot be represented in thought. Another insuperable difficulty presents itself when we contemplate the transfer of Motion. Habit blinds us to the marvellousness of this phenomenon. Familiar with the fact from childhood, we see nothing remarkable in the ability of a moving thing to generate movement in a thing that is stationary. It is, however, impossible to understand it. In what respect does a body after impact differ from itself before impact? What is this added to it which does not sensibly affect any of its properties and yet enables it to traverse space? Here is an object at rest and here is the same object moving. In the one state it has no tendency to change its place, but in the other it is obliged at each instant to assume a new position. What is it which will for ever go on producing this effect without being exhausted? and how does it dwell in the object? The motion you say has been communicated. But how? What has been communicated? The striking body has not transferred a thing to the body struck; and it is equally out of the question to say that it has transferred an attribute. What then has it transferred? Once more there is the old puzzle concerning the connexion between Motion and Rest. A body travelling at a given velocity cannot be brought to a state of rest, or no velocity, without passing through all intermediate velocities. It is quite possible to think of its motion as diminishing insensibly until it becomes infinitesimal; and many will think equally possible to pass in thought from infinitesimal motion to no motion. But this is an error. Mentally follow out the decreasing velocity as long as you please, and there still remains some velocity; and the smallest movement is separated by an impassable gap from no movement. As something, however minute, is infinitely great in comparison with nothing; so is even the least conceivable motion infinite as compared with rest. Thus neither when considered in connexion with Space, nor when considered in connexion with Matter, nor when considered in connexion with Rest, do we find that Motion is truly cognizable. All efforts to understand its essential nature do but bring us to alternative impossibilities of thought. 18. On lifting a chair the force exerted we regard as equal to that antagonistic force called the weight of the chair, and we cannot think of these as equal without thinking of them as like in kind; since equality is conceivable only between things that are connatural. Yet, contrariwise, it is incredible that the force existing in the chair resembles the force present to our minds. It scarcely needs to point out that since the force as known to us is an affection of consciousness, we cannot conceive the force to exist in the chair under the same form without endowing the chair with consciousness. So that it is absurd to think of Force as in itself like our sensation of it, and yet necessary so to think of it if we represent it in consciousness at all. How, again, can we understand the connexion between Force and Matter? Matter is known to us only through its manifestations of Force: abstract its resistance mediately or immediately offered and there remains nothing but empty extension. Yet, on the other hand, resistance is equally unthinkable apart from Matter apart from something extended. Not only are centres of force devoid of extension unimaginable, but we cannot imagine either extended or unextended centres of force to attract and repel other such centres at a distance, without the intermediation of some kind of matter. The hypothesis of Newton, equally with that of Boscovich, is open to the charge that it supposes one thing to act on another through empty space a supposition which cannot be represented in thought. This charge is indeed met by introducing a hypothetical fluid existing among the atoms or centres. But the problem is not thus solved: it is simply shifted, and reappears when the constitution of this fluid is inquired into. How impossible it is to elude the difficulty is best seen in the case of astronomical forces. The Sun gives us sensations of light and heat; and we have ascertained that between the cause as existing in the Sun, and the effect as experienced on the Earth, a lapse of eight minutes occurs: whence unavoidably result in us the conceptions of both a force and a motion. So that for assuming a luminiferous ether, there is the defence, not only that the exercise of force through 92,000,000 of miles of absolute vacuum is inconceivable, but also that it is impossible to conceive motion in the absence of something moved. Similarly in the case of gravitation. Newton described himself as unable to think that the attraction of one body for another at a distance, could be exerted in the absence of an intervening medium. But now let us ask how much the forwarder we are if an intervening medium be assumed. This ether whose undulations according to the received hypothesis constitute heat and light, and which is the vehicle of gravitation how is it constituted? We must regard it in the way that physicists usually regard it, as composed of atoms or molecules which attract and repel one another: infinitesimal it may be in comparison with those of ordinary matter, but still atoms or molecules. And remembering that this ether is imponderable, we are obliged to conclude that the ratio between the interspaces of these atoms and the atoms themselves is immense. Hence we have to conceive these infinitesimal molecules acting on one another through relatively vast distances. How is this conception easier than the other? We still have mentally. to represent a body as acting where it is not, and in the absence of anything by which its action may be transferred; and what matters it whether this takes place on a large or a small scale? Thus we are obliged to conclude that matter, whether ponderable or imponderable, and whether aggregated or in its hypothetical units, acts on matter through absolutely vacant space; and yet this conclusion is unthinkable. Another difficulty of conception, converse in nature but equally insurmountable, must be added. If, on the one hand, we cannot in thought see matter acting upon matter through vacant space; on the other hand, it is incomprehensible that the gravitation of one particle of matter towards another, and towards all others, should be the same whether the intervening space is filled with matter or not. I lift from the ground, and continue to hold, a pound weight. Now, into the vacancy between it and the ground, is introduced a mass of matter of any kind whatever, in any state whatever; and the gravitation of the weight is entirely unaffected. Each individual of the infinity of particles composing the Earth acts on the pound in absolutely the same way, whatever intervenes, or if nothing intervenes. Through eight thousand miles of the Earth's substance, each molecule at the antipodes affects each molecule of the weight, in utter indifference to the fullness or emptiness of the space between them. So that each portion of matter in its dealings with remote portions, treats all intervening portions as though they did not exist; and yet, at the same time, it recognizes their existence with scrupulous exactness in its direct dealings with them. While then it is impossible to form any idea of Force in itself, it is equally impossible to comprehend its mode of exercise. 19. Turning now from the outer to the inner world, let us contemplate, not the agencies to which we ascribe our subjective modifications, but the subjective modifications themselves. These constitute a series. Difficult as we find it distinctly to individualize them, it is nevertheless beyond question that our states of consciousness occur in succession. Is this chain of states of consciousness infinite or finite? We cannot say infinite; not only because we have indirectly reached the conclusion that there was a period when it commenced, but also because all infinity is inconceivable an infinite series included. If we say finite we say it inferentially; for we have no direct knowledge of either of its ends. Go back in memory as far as we may, we are wholly unable to identify our first states of consciousness. Similarly at the other extreme. We infer a termination to the series at a future time, but cannot directly know it; and we cannot really lay hold of that temporary termination reached at the present moment. For the state of consciousness recognized by us as our last, is not truly our last. That any mental affection may be known as one of the series, it must be remembered represented in thought, not presented. The truly last state of consciousness is that which is passing in the very act of contemplating a state just past that in which we are thinking of the one before as the last. So that the proximate end of the change eludes us, as well as the remote end. "But," it may be said, "though we cannot directly know consciousness to be finite in duration, because neither of its limits can be actually reached, yet we can very well conceive it to be so." No: not even this is true. We cannot conceive the terminations of that consciousness which alone we really know our own any more than we can perceive its terminations. For in truth the two acts are here one. In either case such terminations must be, as above said, not presented in thought, but represented; and they must be represented as in the act of occurring. Now to represent the termination of consciousness as occurring in ourselves, is to think of ourselves as contemplating the cessation of the last state of consciousness; and this implies a supposed continuance of consciousness after its last state, which is absurd. Hence, while we are unable to believe or to conceive that the duration of consciousness is infinite, we are equally unable either to know it as finite, or to conceive it as finite: we can only infer from indirect evidence that it is finite. 20. Nor do we meet with any greater success when, instead of the extent of consciousness, we consider its substance. The question What is this that thinks? admits of no better solution than the question to which we have just found none but inconceivable answers. The existence of each individual as known to himself, has always been held the most incontrovertible of truths. To say "I am as sure of it as I am sure that I exist," is, in common speech, the most emphatic expression of certainty. And this fact of personal existence, testified to by the universal consciousness of men, has been made the basis of more philosophies than one. Belief in the reality of self cannot, indeed, be escaped while normal consciousness continues. What shall we say of these successive impressions and ideas which constitute consciousness? Are they affections of something called mind, which, as being the subject of them, is the real ego? If we say this we imply that the ego is an entity. Shall we assert that these impressions and ideas are not the mere superficial changes wrought on some thinking substance, but are themselves the very body of this substance are severally the modified forms which it from moment to moment assumes? This hypothesis, equally with the foregoing, implies that the conscious self exists as a permanent continuous being; since modifications necessarily involve something modified. Shall we then betake ourselves to the sceptic's position, and argue that our impressions and ideas themselves are to us the only existences, and that the personality said to underlie them is a fiction? We do not even thus escape; since this proposition, verbally intelligible but really unthinkable, itself makes the assumption which it professes to repudiate. For how can consciousness be wholly resolved into impressions and ideas, when an impression of necessity imples something impressed? Or again, how can the sceptic who has decomposed his consciousness into impressions and ideas, explain the fact that he considers them as his impressions and ideas? Or once more, if, as he must, he admits that he has an impression of his personal existence, what warrant can he show for rejecting this impression as unreal while he accepts all his other impressions as real? But now, unavoidable as is this belief, it is yet a belief admitting of no justification by reason: nay, indeed, it is a belief which reason, when pressed for a distinct answer, rejects. One of the most recent writers who has touched on this question Mr. Mansel does, indeed, contend that in the consciousness of self we have a piece of real knowledge. His position is that "let system makers say what they will, the unsophisticated sense of mankind refuses to acknowledge that mind is but a bundle of states of consciousness, as matter is (possibly) a bundle of sensible qualities." But this position does not seem a consistent one for a Kantist, who pays but small respect to "the unsophisticated sense of mankind" when it testifies to the objectivity of space. Moreover, it may readily be shown that a cognition of self, properly so called, is negatived by those laws of thought which he emphasizes. The fundamental condition to all consciousness, insisted upon by Mr. Mansel in common with Sir William Hamilton and others, is the antithesis of subject and object. On this "primitive dualism of consciousness," "from which the explanations of philosophy must take their start," Mr. Mansel founds his refutation of the German absolutists. But now what is the corollary, as bearing on the consciousness of self? The mental act in which self is known implies, like every other mental act, a perceiving subject and a perceived object. If, then, the object perceived is self, what is the subject that perceives? or if it is the true self which thinks, what other self can it be that is thought of? Clearly, a true cognition of self implies a state in which the knowing and the known are one in which subject and object are identified; and this Mr. Mansel rightly holds to be the annihilation of both. So that the personality of which each is conscious, and the existence of which is to each a fact beyond all others the most certain, is yet a thing which cannot be known at all, in the strict sense of the word. 21. Ultimate Scientific Ideas, then, are all representative of realities that cannot be comprehended. After no matter how great a progress in the colligation of facts and the establishment of generalizations ever wider and wider, the fundamental truth remains as much beyond reach as ever. The explanation of that which is explicable, does but bring into greater clearness the inexplicableness of that which remains behind. Alike in the external and the internal worlds, the man of science sees himself in the midst of perpetual changes of which he can discover neither the beginning nor the end. If he allows himself to entertain the hypothesis that the Universe originally existed in a diffused form, he finds it impossible to conceive how this came to be so; and equally, if he speculates on the future, he can assign no limit to the grand succession of phenomena ever unfolding themselves before him. In like manner if he looks inward he perceives that both ends of the thread of consciousness are beyond his grasp. Neither end can be represented in thought. When, again, he turns from the succession of phenomena, external or internal, to their intrinsic nature, he is just as much at fault. Supposing him in every case able to resolve the appearances, properties, and movements of things, into manifestations of Force in Space and Time; he still finds that Force, Space, and Time pass all understanding. Similarly, though analysis of mental actions may finally bring him down to sensations, as the original materials out of which all thought is woven, yet he is little forwarder; for he can give no account either of sensations themselves or of that which is conscious of sensations. Objective and subjective things he thus ascertains to be alike inscrutable in their substance and genesis. In all directions his investigations eventually bring him face to face with an insoluble enigma; and be ever more clearly perceives it to be an insoluble enigma. He learns at once the greatness and the littleness of the human intellect its power in dealing with all that comes within the range of experience, its impotence in dealing with all that transcends experience. He, more than any other, truly knows that in its ultimate nature nothing can be known. Chapter 4 The Relativity of all Knowledge 22. The same conclusion is thus arrived at from whichever point we set out. Ultimate religious ideas and ultimate scientific ideas, alike turn out to be merely symbols of the actual, not cognitions of it. The conviction, so reached, that human intelligence is incapable of absolute knowledge, is one that has been slowly gaining ground. Each new ontological theory, propounded in lieu of previous ones shown to be untenable, has been followed by a new criticism leading to a new scepticism. All possible conceptions have been one by one tried and found wanting; and so the entire field of speculation has been gradually exhausted without positive result: the only result reached being the negative one above stated that the reality existing behind all appearances is, and must ever be, unknown. To this conclusion almost every thinker of note has subscribed. "With the exception," says Sir William Hamilton, "of a few late Absolutist theorizers in Germany, this is, perhaps, the truth of all others most harmoniously re-echoed by every philosopher of every school." And among these he names Protagoras, Aristotle, St. Augustin, Boethius, Averroes, Albertus Magnus, Gerson, Leo Hebraeus, Melancthon, Scaliger, Francis Piccolomini, Giordano Bruno, Campanella, Bacon, Spinoza, Newton, Kant. It remains to point out how this belief may be established rationally, as well as empirically. Not only is it that, as in the earlier thinkers above named, a vague perception of the inscrutableness of things in themselves results from discovering the illusiveness of sense-impressions; and not only is it that, as shown in the foregoing chapters, experiments evolve alternative impossibilities of thought out of every fundamental conception; but it is that the relativity of our knowledge may be proved analytically. The induction drawn from general and special experiences, may be confirmed by a deduction from the nature of our intelligence. Two ways of reaching such a deduction exist. Proof that our cognitions are not, and never can be, absolute, is obtainable by analyzing either the product or thought, or the process of thought. Let us analyze each. 23. If, when walking through the fields some day in September, you hear a rustle a few yards in advance, and on observing the ditch- side where it occurs, see the herbage agitated, you will probably turn towards the spot to learn by what this sound and motion are produced. As you approach there flutters into the ditch a partridge; on seeing which your curiosity is satisfied you have what you call an explanation of the appearances. The explanation, mark, amounts to this; that whereas throughout life you have had countless experiences of disturbance among small stationary bodies, accompanying the movement of other bodies among them, and have generalized the relation between such disturbances and such movements, you consider this particular disturbance explained, on finding it to present an instance of the like relation. Suppose you catch the partridge; and, wishing to ascertain why it did not escape, examine it, and find at one spot a trace of blood on its feathers. You now understand, as you say, what has disabled the partridge. It has been wounded by a sportsman adds another case to the cases already seen by you, of birds being killed or injured by the shot discharged at them from fowling-pieces. And in assimilating this case to other such cases, consists your understanding of it. But now, on consideration, a difficulty suggests itself. Only a single shot has struck the partridge, and that not in a vital place: the wings are uninjured, as are also those muscles which move them; and the creature proves by its struggles that it has abundant strength. Why then, you inquire of yourself, does it not fly? Occasion favouring, you put the question to an anatomist, who furnishes you with a solution. He points out that this solitary shot has passed close to the place at which the nerve supplying the wing- muscles of one side, diverges from the spine; and explains that a slight injury to this nerve, extending even to the rupture of a few fibres, may by preventing a perfect co-ordination in the actions of the two wings, destroy the power of flight. You are no longer puzzled. But what has happened? what has changed your state from one of perplexity to one of comprehension? Simply the disclosure of a class of previously known cases, along with which you can include this case. The connexion between lesions of the nervous system and paralysis of limbs has been already many times brought under your notice; and you here find a relation of cause and effect that is essentially similar. Let us suppose you are led to ask the anatomist questions about some organic actions which, remarkable though they are, you had not before cared to understand. How is respiration effected? You ask why does air periodically rush into the lungs? The answer is that influx of air is caused by an enlargement of the thoracic cavity, due, partly to depression of the diaphragm, partly to motion of the ribs. But how can these bony hoops move, and how does motion of them enlarge the cavity? In reply the anatomist explains that though attached by their ends the ribs can move a little round their points of attachment; he then shows you that the plane of each pair of ribs makes an acute angle with the spine; that this angle widens when the sternal ends of the ribs are raised; and he makes you realize the consequent dilatation of the cavity, by pointing out how the area of a parallelogram increases as its angles approach to right angles: you understand this special fact when you see it to be an instance of a general geometrical fact. There still arises, however, the question why does the air rush into this enlarged cavity? To which comes the answer that, when the thoracic cavity is enlarged, the contained air, partially relieved from pressure, expands, and so loses some of its resisting Power; that hence it opposes to the pressure of the external air a less pressure; and that as air, like every other fluid, presses equally in all directions, motion must result along any line in which the resistance is less than elsewhere; whence follows an inward current. And this interpretation you recognize as one, when a few facts of like kind, exhibited more plainly in a visible fluid such as water, are cited in illustration. Again, after being shown that the limbs are compound levers acting in essentially the same way as levers of iron, you would consider yourself as having obtained a partial rationale of animal movements. The contraction of a muscle, seeming before quite unaccountable, would seem less unaccountable were you shown how, by a galvanic current, a series of soft iron magnets could be made to shorten itself through the attraction of each magnet for its neighbours: an alleged analogy which especially answers the purpose of our argument, since, whether real or fancied, it equally illustrates the mental illumination that results on finding a class of cases within which a particular case may perhaps be included. Similarly when you learn that animal heat arises from chemical combination, and so may be classed with heat evolved in other chemical combinations when you learn that the absorption of nutrient liquids through the coats of the intestines is an instance of osmotic action when you learn that the changes undergone by food during digestion, are like changes artificially producible in the laboratory; you regard yourself as knowing something about the natures of these phenomena. Observe now what we have been doing. We began with special and concrete facts. In explaining each, and afterwards explaining the general facts of which they are instances, we have got down to certain highly general facts: to a geometrical principle, to a simple law of mechanical action, to a law of fluid equilibrium to truths in physics, in chemistry, in thermology. The particular phenomena with which we set out have been merged in larger and larger groups of phenomena; and as they have been so merged, we have arrived at solutions we consider profound in proportion as this process has been carried far. Still deeper explanations are simply further steps in the same direction. When, for instance, it is asked why the law of action of the lever is what it is, or why fluid equilibrium and fluid motion exhibit the relations they do, the answer furnished by mathematicians consists in the disclosure of the principle of virtual velocities a principle holding true alike in fluids and solids a principle under which the others are comprehended. Is this process limited or unlimited? Can we go on for ever explaining classes of facts by including them in larger classes; or must we eventually come to a largest class? The supposition that the process is unlimited, were any one absurd enough to espouse it, would still imply that an ultimate explanation could not be reached, since infinite time would be required to reach it. While the unavoidable conclusion that it is limited, equally implies that the deepest fact cannot be understood. For if the successively deeper interpretations of Nature which constitute advancing knowledge, are merely successive inclusions of special truths in general truths, and of general truths in truths still more general; it follows that the most general truth, not admitting of inclusion in any other, does not admit of interpretation. Of necessity, therefore, explanation must eventually bring us down to the inexplicable. Comprehension must become something other than comprehension, before the ultimate fact can be comprehended. 24. The inference which is thus forced on us when we analyze the product of thought, as exhibited objectively in scientific generalizations, is equally forced on us by an analysis of the process of thought, as exhibited subjectively in consciousness. The demonstration of the relative character of our knowledge, as deduced from the nature of intelligence, has been brought to its most definite shape by Sir William Hamilton. I cannot here do better than extract from his essay on the "Philosophy of the Unconditioned," the passage containing the substance of his doctrine. "The unconditionally unlimited, or the Infinite, the unconditionally limited, or the Absolute, cannot positively be construed to the mind; they can be conceived, only by a thinking away from, or abstraction of, those very conditions under which thought itself is realized; consequently, the notion of the Unconditioned is only negative, negative of the conceivable itself. For example, on the one hand we can positively conceive, neither an absolute whole, that is, a whole so great, that we cannot also conceive it as a relative part of a still greater whole; nor an absolute part, that is, a part so small, that we cannot also conceive it as a relative whole, divisible into smaller parts. On the other hand, we cannot positively represent, or realize, or construe to the mind (as here understanding and imagination coincide), an infinite whole, for this could only be done by the infinite synthesis in thought of finite wholes, which would itself require an infinite time for its accomplishment; nor, for the same reason, can we follow out in thought an infinite divisibility of parts. The result is the same, whether we apply the process to limitation in space, in time, or in degree. * * * "As the conditionally limited (which we may briefly call the conditioned) is thus the only possible object of knowledge and of positive thought thought necessarily supposes conditions. To think is to condition; and conditional limitation is the fundamental law of the possibility of thought. For, as the greyhound cannot outstrip his shadow, nor (by a more appropriate simile) the eagle outsoar the atmosphere in which he floats, and by which alone he may be supported; so the mind cannot transcend that sphere of limitation, within and through which exclusively the possibility of thought is realized. * * * How, indeed, it could ever be doubted that thought is only of the conditioned, may well be deemed a matter of the profoundest admiration. Thought cannot transcend consciousness; consciousness is only possible under the antithesis of a subject and object of thought, known only in correlation, and mutually limiting each other; while, independently of this, all that we know either of subject or object, either of mind or matter, is only a knowledge in each of the particular, of the plural, of the different, of the modified, of the phaenomenal. We admit that the consequence of this doctrine is, that philosophy, if viewed as more than a science of the conditioned, is impossible. Departing from the particular, we admit, that we can never, in our highest generalizations, rise above the finite; that our knowledge, whether of mind or matter, can be nothing more than a knowledge of the relative manifestations of an existence, which in itself it is our highest wisdom to recognize aS beyond the reach of philosophy. * * * "We are thus taught the salutary lesson, that the capacity of thought is not to be constituted into the measure of existence; and are warned from recognizing the domain of our knowledge as necessarily co-extensive with the horizon of our faith. And by a wonderful revelation, we are thus, in the very consciousness of our inability to conceive aught above the relative and finite, inspired with a belief in the existence of something unconditioned beyond the sphere of all comprehensible reality." Clear and conclusive as this statement of the case appears when carefully studied, it is expressed in so abstract a manner as to be not very intelligible to the general reader. A more popular presentation of it. with illustrative applications, as given by Mr. Mansel in his Limits of Religious Thought, will make it more fully understood. The following extracts, which I take the liberty of making from his pages, will suffice. "The very conception of consciousness in whatever mode it may be manifested, necessarily implies distinction between one object and another. To be conscious, we must be conscious of something; and that something can only be known, as that which it is, by being distinguished from that which it is not. But distinction is necessarily imitation; for, if one object is to be distinguished from another, it must possess some form of existence which the other has not, or it must not possess some form which the other has. * * * If all thought is limitation; if whatever we conceive is, by the very act of conception, regarded as finite, the infinite, from a human point of view, is merely a name for the absence of those conditions under which thought is possible. To speak of a Conception of the Infinite is, therefore, at once to affirm those conditions and to deny them. The contradiction, which we discover in such a conception, is only that which we have ourselves placed there, by tacitly assuming the conceivability of the inconceivable. The condition of consciousness is distinction; and condition of distinction is limitation. We can have no consciousness of Being in general which is not some Being in particular: a thing, in consciousness, is one thing out of many. In assuming the possibility of an infinite object of consciousness, I assume, therefore, that it is at the same time limited and unlimited; actually something, without which it could not be an object of consciousness, and actually nothing, without which it could not be infinite. * * * "A second characteristic of Consciousness is, that it is only possible in the form of a relation. There must be a Subject, or person conscious, and an Object, or thing of which he is conscious. There can be no consciousness without the union of these two factors; and, in that union, each exists only as it is related to the other. The subject is a subject, only in so far as it is conscious of an object; the object is an object, only in so far as it is apprehended by a subject: and the destruction of either is the destruction of consciousness itself. It is thus manifest that a consciousness of the Absolute is equally self-contradictory with that of the Infinite. To be conscious of the Absolute as such, we must know that an object, which is given in relation to our consciousness, is identical with one which exists in its own nature, out of all relation to consciousness. But to know this identity, we must be able to compare the two together; and such a comparison is itself a contradiction. We are in fact required to compare that of which we are conscious with that of which we are not conscious; the comparison itself being an act of consciousness, and only possible through the consciousness of both its objects. It is thus manifest that, even if we could be conscious of the absolute we could not possibly know that it is the absolute: and, as we can be conscious of an object as such, only by knowing it to be what it is, this is equivalent to an admission that we cannot be conscious of the absolute at all. As an object of COnsciousness, every thing is necessarily relative; and what a thing may be out of consciousness no mode of consciousness can tell us. * * * "This contradiction, again, admits of the same explanation as the former, * * * Existence, as we conceive it, is but a name for the several ways in which objects are presented to our consciousness, a general term, embracing a variety of relations. The Absolute, on the other hand, is a term expressing no object of thought, but only a denial of the relation by which thought is constituted." Here let me point out how the same general inference may be evolved from another fundamental condition to thought, omitted by Sir W. Hamilton and not supplied by Mr. Mansel; a condition which, under its obverse aspect, we have already contemplated in the last section. Every complete act of consciousness, besides distinction and relation, also implies likeness. Before it can constitute a piece of knowledge, or even become an idea, a mental state must be known not only as separate in kind or quality from certain foregoing states to which it is known as related by succession, but it must further be known as of the same kind or quality with certain other foregoing states. That organization of changes which constitutes thinking, involves continuous integration as well as continuous differentiation. Were each new affection of the mind perceived simply as an affection in some way contested with preceding ones were there but a chain of impressions, each of which as it arose was merely distinguished from its predecessors; consciousness would be a chaos. To produce that orderly consciousness which we call intelligence, there requires the assimilation of each impression to others that occurred earlier in the series. Both the successive mental states, and the successive relations which they bear to one another, must be classified; and classification involves not only a parting of the unlike, but also a binding together of the like. In brief, a true cognition is possible only through an accompanying recognition. Should it be objected that if so there cannot be a first cognition, and hence there can be no cognition, the reply is that cognition proper arises gradually that during the first stage of incipient intelligence, before the feelings produced by intercourse with the outer world have been put into order, there are no cognitions; and that, as every infant shows us, these slowly emerge out of the confusion of unfolding consciousness as fast as the experiences are arranged into groups as fast as the most frequently repeated sensations, and their relations to one another, become familiar enough to admit of their recognition as such or such, whenever they recur. Should it be further objected that if cognition presupposes recognition, there can be no cognition, even by an adult, of an object never before seen; there is still the sufficient answer that in so far as it is not assimilated to previously-seen objects it is not known, and that it is known only in so far as it is assimilated
