. . . I laid it down as a rule that whenever I heard a more correct opinion on any subject whatever advanced, I would, with joy and humility, give up my earlier opinion: being well aware that what we know is vastly less than what we do not know. . . . I avow it to be my purpose to defend the truth which God has enabled me to know, and especially the truth of the Holy Scriptures, even to death; since I know that the truth stands, and is forever mighty, and abides eternally; and with her there is no respect of persons. . . . the truth itself triumphs over everything and is mighty forever; who, but a fool, would venture to condemn or to affirm any article, especially in what pertains to faith and manners, until he has informed himself about the truth of it?
- John Huss, 1369-1415, burned at the stake for his beliefs
