Thomas Paine on Ethics

"When we are planning for posterity, we ought to remember that virtue is not hereditary."

"Whatever is my right as a man is also the right of another; and it becomes my duty to guarantee as well as to possess."

"It is the duty of every man, so far as his ability extends, to detect and expose delusion and error."

"A thing, moderately good, is not so good as it ought to be. Moderation in temper, is always a virtue; but moderation in principle, is a species of vice."

"we hold that the moral obligation of providing for old age, helpless infancy, and poverty, is far superior to that of supplying the invented wants of courtly extravagance, ambition and intrigue."

"It lost ground from contempt more than from hatred; and was rather jeered at as an ass, than dreaded as a lion. This is the general character of aristocracy, or what are called Nobles or Nobility, or rather No-ability, in all countries."

"Our Traders in MEN must know the wickedness of that SLAVE-TRADE, if they attend to reasoning, or the dictates of their own hearts; and such as shun and stiffle all these, wilfully sacrifice Conscience, and the character of integrity to that golden Idol."

"All religions are in their nature kind and benign, and united with principles of morality. They could not have made proselytes at first by professing anything that was vicious, cruel, persecuting, or immoral. Like everything else, they had their beginning; and they proceeded by persuasion, exhortation, and example. How then is it that they lose their native mildness, and become morose and intolerant?"

"The people of America had been bred up in the same prejudices against France, which at that time characterized the people of England; but experience and an acquaintance with the French Nation have most effectually shown to the American the falsehood of those prejudices; and I do not believe that a more cordial and confidential intercourse exists between any two countries than between America and France."

"While the characters of men are forming, as is always the case in revolutions, there is a reciprocal suspicion, and a disposition to misinterpret each other; and even parties directly opposite in principle will sometimes concur in pushing forward the same movement with very different views, and with the hopes of its producing very different consequences. A great deal of this may be discovered in this embarrassed affair, and yet the issue of the whole was what nobody had in view."

"It is never to be expected in a revolution that every man is to change his opinion at the same moment. There never yet was any truth or any principle so irresistibly obvious that all men believed it at once. Time and reason must cooperate with each other to the final establishment of any principle; and therefore those who may happen to be first convinced have not a right to persecute others, on whom conviction operates more slowly. The moral principle of revolutions is to instruct, not to destroy."
