“It is more important that innocence be protected than it is that guilt be punished, for guilt and crimes are so frequent in this world that they cannot all be punished.But if innocence itself is brought to the bar and condemned, perhaps to die, then the citizen will say, 'whether I do good or whether I do evil is immaterial, for innocence itself is no protection,' and if such an idea as that were to take hold in the mind of the citizen that would be the end of security whatsoever.”

“There is no greater guilt than the unneccessary war.”

“Now be it known, That I John Adams, President of the United States of America, having seen and considered the said Treaty do, by and with the advice and consent of the Senate, accept, ratify, and confirm the same, and every clause and article thereof. And to the End that the said Treaty may be observed, and performed with good Faith on the part of the United States, I have ordered the premises to be made public; And I do hereby enjoin and require all persons bearing office civil or military within the United States, and all other citizens or inhabitants thereof, faithfully to observe and fulfill the said Treaty and every clause and article thereof.”

“We think ourselves possessed, or at least we boast that we are so, of liberty of conscience on all subjects and of the right of free inquiry and private judgment in all cases, and yet how far are we from these exalted privileges in fact. There exists, I believe, throughout the whole Christian world, a law which makes it blasphemy to deny, or to doubt the divine inspiration of all the books of the Old and New Testaments, from Genesis to Revelations. In most countries of Europe it is punished by fire at the stake, or the rack, or the wheel. In England itself, it is punished by boring through the tongue with a red-hot poker. In America it is not much better; even in our Massachusetts, which, I believe, upon the whole, is as temperate and moderate in religious zeal as most of the States, a law was made in the latter end of the last century, repealing the cruel punishments of the former laws, but substituting fine and imprisonment upon all those blasphemies upon any book of the Old Testament or New. Now, what free inquiry, when a writer must surely encounter the risk of fine or imprisonment for adducing any arguments for investigation into the divine authority of those books? Who would run the risk of translating Volney's Recherches Nouvelles? Who would run the risk of translating Dupuis? But I cannot enlarge upon this subject, though I have it much at heart. I think such laws a great embarrassment, great obstructions to the improvement of the human mind. Books that cannot bear examination, certainly ought not to be established as divine inspiration by penal laws... but as long as they continue in force as laws, the human mind must make an awkward and clumsy progress in its investigations. I wish they were repealed.{Letter to Thomas Jefferson, January 23, 1825}”

“There is something splendid about innocence; but what is bad about it, in turn, is that it cannot protect itself very well and is easily seduced.”

“Great is the guilt of an unnecessary war.”

“If I could, Sister James, I would certainly choose to live in innocence. But innocence can only be wisdom in a world without evil. Situations arise and we are confronted with wrongdoing and the need to act.”
