This modesty in a sect is perhaps a singular instance in the history of mankind, every other sect supposing itself in possession of all truth, and that those who differ are so far in the wrong ; like a man traveling in foggy weather, those at some distance before him on the road he sees wrapped up in the fog, as well as those behind him, and also the people in the fields on each side, but near him all appears clear, tho' in truth he is as much in the fog as any of them.
Benjamin FranklinWithout freedom of thought, there can be no such thing as wisdom; and no such thing as public liberty without freedom of speech; which is the right of every man as far as by it he does not hurt or control the right of another; and this is the only check it ought to suffer and the only bounds it ought to know.... Whoever would overthrow the liberty of a nation must begin by subduing the freedom of speech, a thing terrible to traitors.
Benjamin Franklin
