“Laws for the liberal education of youth, especially of the lower class of people, are so extremely wise and useful, that, to a humane and generous mind, no expense for this purpose would be thought extravagant.”

“Children should be educated and instructed in the principles of freedom. Aristotle speaks plainly to this purpose, saying, 'that the institution of youth should be accommodated to that form of government under which they live; forasmuch as it makes exceedingly for the preservation of the present government, whatsoever it be.”

“Wisdom and knowledge, as well as virtue, diffused generally among the body of the people being necessary for the preservation of their rights and liberties; and as these depend on spreading the opportunities and advantages of education in various parts of the country, and among the different orders of the people, it shall be the duty of legislators and magistrates in all future periods of this commonwealth to cherish the interests of literature and the sciences, and all seminaries of them, especially the university at Cambridge, public schools, and grammar schools in the towns; to encourage private societies and public institutions, rewards and immunities, for the promotion of agriculture, arts, sciences, commerce, trades, manufactures, and a natural history of the country; to countenance and inculcate the principles of humanity and general benevolence, public and private charity, industry and frugality, honesty and punctuality in their dealings, sincerity, good humor, and all social affections, and generous sentiments among the people. ”

“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}”

“If the way to do good to my country were to render myself popular, I could easily do it. But extravagant popularity is not the road to public advantage.”

“Tacitus appears to have been as great an enthusiast as Petrarch for the revival of the republic and universal empire. He has exerted the vengeance of history upon the emperors, but has veiled the conspiracies against them, and the incorrigible corruption of the people which probably provoked their most atrocious cruelties. Tyranny can scarcely be practised upon a virtuous and wise people.”

“We have no government armed with power capable of contending with human passions unbridled by morality and religion. Avarice, ambition, revenge or gallantry would break the strongest cords of our Constitution as a whale goes through a net. Our Constitution is designed only for a moral and religious people. It is wholly inadequate for any other.”
