The malicious have a dark happiness.

Ideas can no more flow backward than can a river.

Everything bows to success, even grammar.

All roads are blocked to a philosophy which reduces everything to the word "no." To "no" there is only one answer and that is "yes." Nihilism has no substance. There is no such thing as nothingness, and zero does not exist. Everything is something. Nothing is nothing. Man lives more by affirmation than by bread.

All who suffer are full of hatred; all who live drag a remorse: the dead alone have broken their chains.

Smallness in a great man seems smaller by its disproportion with all the rest.

It is in the name of Moses that Bellarmin thunderstrikes Galileo; and this great vulgarizer of the great seeker Copernicus, Galileo, the old man of truth, the magian of the heavens, was reduced to repeating on his knees word for word after the inquisitor this formula of shame: "Corde sincera et fide non ficta abjuro maledico et detestor supradictos errores et hereses." Falsehood put an ass's hood on science.
