“I would advise you therefore not to attempt unchaining the Tyger, but to burn this Piece before it is seen by any other Person”
Letter to unknown recipient (13 December 1757) http://teachingamericanhistory.org/library/index.asp?document=473. The letter was published as early as 1817 (William Temple Franklin, The Works of Benjamin Franklin, volume VI, pp. 243-244). In 1833 William Wisner ("Don't Unchain the Tiger," American Tract Society, 1833) identified the recipient as probably Thomas Paine, which was echoed by Jared Sparks in his 1840 edition of Franklin's works (volume x, p. 281). (Presumably it would have been directed against The Age of Reason, his deistic work which criticized orthodox Christianity.) Calvin Blanchard responded to Wisner's tract in The Life of Thomas Paine (1860), pp. 73-74, by noting that Franklin died in 1790, while Paine did not begin writing The Age of Reason until 1793, and incorrectly concluded that the letter did not exist. Paul F. Boller, Jr., and John George, included it in They Never Said It: A Book of Fake Quotes, Misquotes, & Misleading Attributions (1989), on p. 28. Moncure Daniel Conway pointed out (The Life of Thomas Paine, 1892, vol I, p. vii) that the recipient could not be Thomas Paine, in that he, unlike Paine, denied a "particular providence". The intended recipient remains unidentified.
Parts of the above have also been rearranged and paraphrased:
I would advise you not to attempt Unchaining The Tiger, but to burn this piece before it is seen by any other person.
If men are so wicked with religion, what would they be if without it?
If men are so wicked with religion, what would they be Without it? Think how many inconsiderate and inexperienced youth of both sexes there are, 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.
Epistles
Context: I have read your Manuscript with some Attention. By the Arguments it contains against the Doctrine of a particular Providence, tho’ you allow a general Providence, you strike at the Foundation of all Religion: For without the Belief of a Providence that takes Cognizance of, guards and guides and may favour particular Persons, there is no Motive to Worship a Deity, to fear its Displeasure, or to pray for its Protection. I will not enter into any Discussion of your Principles, tho’ you seem to desire it; At present I shall only give you my Opinion that tho’ your Reasonings 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 your self, 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 Advantages 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 Proportion of Mankind consists of weak and ignorant Men and Women, and of inexperienc’d and 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 on a less hazardous Subject, and thereby obtain Rank with our most distinguish’d Authors. For among us, it is not necessary, as among the Hottentots that a Youth to be receiv’d into the Company of Men, should prove his Manhood by beating his Mother. I would advise you therefore not to attempt unchaining the Tyger, but to burn this Piece before it is seen by any other Person, whereby you will save yourself a great deal of Mortification from the Enemies it may raise against you, and perhaps a good deal of Regret and Repentance. If Men are so wicked as we now see them with Religion what would they be if without it?

All and Everything: Views from the Real World (1973)
Context: LIBERATION LEADS TO LIBERATION. These are the first words of truth — not truth in quotation marks but truth in the real meaning of the word; truth which is not merely theoretical, not simply a word, but truth that can be realized in practice. The meaning behind these words may be explained as follows:
By liberation is meant the liberation which is the aim of all schools, all religions, at all times.
This liberation can indeed be very great. All men desire it and strive after it. But it cannot be attained without the first liberation, a lesser liberation. The great liberation is liberation from influences outside us. The lesser liberation is liberation from influences within us.
At first, for beginners, this lesser liberation appears to be very great, for a beginner depends very little on external influences. Only a man who has already become free of inner influences falls under external influences.
Inner influences prevent a man from falling under external influences. Maybe it is for the best. Inner influences and inner slavery come from many varied sources and many independent factors — independent in that sometimes it is one thing and sometimes another, for we have many enemies.
There are so many of these enemies that life would not be long enough to struggle with each of them and free ourselves from each one separately. So we must find a method, a line of work, which will enable us simultaneously to destroy the greatest possible number of enemies within us from which these influences come.
I said that we have many independent enemies, but the chief and most active are vanity and self-love. One teaching even calls them representatives and messengers of the devil himself.
For some reason they are also called Mrs. Vanity and Mr. Self-Love.
As I have said, there are many enemies. I have mentioned only these two as the most fundamental. At the moment it is hard to enumerate them all. It would be difficult to work on each of them directly and specifically, and it would take too much time since there are so many. So we have to deal with them indirectly in order to free ourselves from several at once.
These representatives of the devil stand unceasingly at the threshold which separates us from the outside, and prevent not only good but also bad external influences from entering. Thus they have a good side as well as a bad side.
For a man who wishes to discriminate among the influences he receives, it is an advantage to have these watchmen. But if a man wishes all influences to enter, no matter what they may be — for it is impossible to select only the good ones — he must liberate himself as much as possible, and finally altogether, from these watchmen, whom some considerable undesirable.
For this there are many methods, and a great number of means. Personally I would advise you to try freeing yourselves and to do so without unnecessary theorizing, by simple reasoning, active reasoning, within yourselves.

The Art of Persuasion
Context: I would inquire of reasonable persons whether this principle: Matter is naturally wholly incapable of thought, and this other: I think, therefore I am, are in fact the same in the mind of Descartes, and in that of St. Augustine, who said the same thing twelve hundred years before.... I am far from affirming that Descartes is not the real author of it, even if he may have learned it only in reading this distinguished saint; for I know how much difference there is between writing a word by chance without making a longer and more extended reflection on it, and perceiving in this word an admirable series of conclusions, which prove the distinction between material and spiritual natures, and making of it a firm and sustained principle of a complete metaphysical system, as Descartes has pretended to do.... it is on this supposition that I say that this expression is as different in his writings from the saying in others who have said it by chance, as in a man full of life and strength, from a corpse.
