Benjamin Franklin To Thomas Paine

Benjamin Franklin and Thomas Paine maintained a friendship throughout the Revolutionary age. In fact, many believed that Franklin had authored Paine's Common Sense. When a concerned Franklin read the first draft of Paine's Age of Reason in 1785, he urged Paine to burn it before anyone else read it. This was Franklin's advice:
I have read your manuscript with some attention. By the argument it contains against a particular Providence, though you allow a general Providence, you strike at the foundations of all religion. For, without the belief of a Providence that takes cognisance of, guards, and guides, and may favor particular persons, there is no motive to worship a Deity, to fear his displeasure, or to pray for his protection. I will not enter into any discussion of your principles, though you seem to desire it. At present I shall only give you my opinion that, though your reasons are subtle, and may prevail with some readers, you will not succeed so as to change the general sentiments of mankind on that subject, and the consequence of printing this piece will be, a great deal of odium drawn upon yourself, mischief to you, and no benefit to others. He that spits against the wind spits in his own face.

But were you to succeed, do you imagine any good would be done by it? You yourself may find it easy to live a virtuous life, without the assistance afforded by religion; you having a clear perception of the advantage of virtue, and the disadvantages of vice, and possessing a strength of resolution sufficient to enable you to resist common temptations. But think how great a portion of mankind consists of weak and ignorant men and women, and of inexperienced, inconsiderate youth of both sexes, who have need of the motives of religion to restrain them from vice, to support their virtue, and retain them in the practice of it till it becomes habitual, which is the great point for its security. And perhaps you are indebted to her originally, that is to your religious education, for the habits of virtue upon which you now justly value yourself. You might easily display your excellent talents of reasoning upon a less hazardous subject, and thereby obtain a rank with our most distinguished authors. For among us it is not necessary, as among the Hottentots, that a youth, to be raised into the company of men, should prove his manhood by beating his mother.

I would advise you, therefore, not to attempt unchaining the tiger, but to burn this piece before it is seen by any other person, whereby you will save yourself a great deal of mortification by the enemies it may raise against you, and perhaps a great deal of regret and repentance. If men are so wicked with religion,what would they be if without it?
