“The weak, when they have authority, surround themselves with the weak. It is, indeed, a vice of rulers that men who have exceptional ability and worth are offensive to them, since they whose greatness is due to their position find it difficult to love those whom inner power makes great.”

Context: If these rules have not been well observed in the first constitution, or from the changes of times, corruption of manners, insensible encroachments, or violent usurpations of princes, have been rendered ineffectual, and the people exposed to all the calamities that may be brought upon them by the weakness, vices, and malice of the prince, or those who govern him, I confess the remedies are more difficult and dangerous; but even in those cases they must be tried. Nothing can be feared that is worse than what is suffered, or must in a short time fall upon those who are in this condition. They who are already fallen into all that is odious, shameful, and miserable, cannot justly fear. When things are brought to such a pass, the boldest counsels are the most safe; and if they must perish who lie still, and they can but perish who are most active, the choice is easily made. Let the danger be never so great, there is a possibility of safety, whilst men have life, hands, arms, and courage to use them; but that people must certainly perish, who tamely suffer themselves to be oppressed, either by the injustice, cruelty, and malice of an ill magistrate, or by those who prevail upon the vices and infirmities of weak princes. It is in vain to say, that this may give occasion to men of raising tumults, or civil war; for tho' these are evils, yet they are not the greatest of evils. Civil war, in Macchiavel's account, is a disease; but tyranny is the death of a state. Gentle ways are first to be used, and it is best if the work can be done by them; but it must not be left undone, if they fail. It is good to use supplications, advices, and remonstrances; but those who have no regard to justice, and will not hearken to counsel, must be constrained. It is folly to deal otherwise with a man who will not be guided by reason, and a magistrate who despises the law; or rather, to think him a man, who rejects the essential principle of a man; or to account him a magistrate, who overthrows the law by which he is a magistrate. This is the last result; but those nations must come to it, which cannot otherwise be preserved.

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?

The Pathway of Peace (1923)
Context: Time has shown how illusory are alliances of great powers so far as the maintenance of peace is concerned.
In considering the use of international force to secure peace, we are again brought to the fundamental necessity of common accord. If the feasibility of such a force be conceded for the purpose of maintaining adjudications of legal right, this is only because such an adjudication would proceed upon principles commonly accepted, and thus forming part of international law, and upon the common agreement to respect the decision of an impartial tribunal in the application of such principles. This is a limited field where force is rarely needed and where the sanctions of public opinion and the demands of national honor are generally quite sufficient to bring about acquiescence in judicial awards. But in the field of conflicting national policies, and what are deemed essential interests, when the smoldering fires of old grievances have been fanned into a flame by a passionate sense of immediate injury, or the imagination of peoples is dominated by apprehension of present danger to national safety, or by what is believed to be an assault upon national honor, what force is to control the outbreak? Great powers agreeing among themselves may indeed hold small powers in check. But who will hold great powers in check when great powers disagree?.
