"No experiment can be more interesting than that we are now trying, and which we trust will end in establishing the fact, that man may be governed by reason and truth. Our first object should therefore be, to leave open to him all the avenues to truth. The most effectual hitherto found, is the freedom of the press. It is, therefore, the first shut up by those who fear the investigation of their actions." - Thomas Jefferson to John Tyler, 1804. ME 11:33 "I was bold in the pursuit of knowledge, never fearing to follow truth and reason to whatever results they led, and bearding every authority which stood in their way." - Thomas Jefferson to Thomas Cooper, 1814. ME 14:85 "It [appears] that however certain forms of government are better calculated than others to protect individuals in the free exercise of their natural rights, and are at the same time themselves better guarded against degeneracy, yet experience [has] shown that, even under the best forms, those entrusted with power have, in time and by slow operations, perverted it into tyranny." --Thomas Jefferson: Diffusion of Knowledge Bill, 1779. FE 2:220, Papers 2:526 "Man once surrendering his reason, has no remaining guard against absurdities the most monstrous, and like a ship without rudder, is the sport of every wind. With such persons, gullibility, which they call faith, takes the helm from the hand of reason, and the mind becomes a wreck." --Thomas Jefferson to James Smith, 1822. ME 15:409 "We shall have our follies without doubt. Some one or more of them will always be afloat. But ours will be the follies of enthusiasm, not of bigotry, not of Jesuitism. Bigotry is the disease of ignorance, of morbid minds; enthusiasm of the free and buoyant. Education and free discussion are the antidotes of both. We are destined to be a barrier against the return of ignorance and barbarism." --Thomas Jefferson to John Adams, 1816. ME 15:58
