Maybe you who condemn me are in greater fear than I who am condemned.

I beg you, reject antiquity, tradition, faith, and authority! Let us begin anew by doubting everything we assume has been proven!

My son, I do not say these are foals and those asses, these little monkeys and those great baboons, as you would have me do. As I told you from the first, I regard them as earth's heroes. But I do not wish to believe them without cause, nor to accept those propositions whose antitheses (as you must have understood if you are not both blind and deaf) are so compellingly true.
