"If you tell the truth you don't have to remember anything."

"Most writers regard truth as their most valuable possession, and therefore are most economical in its use."

"A man is never more truthful than when he acknowledges himself a liar."

"When the doctrine of allegiance to party can utterly up-end a man's moral constitution and make a temporary fool of him besides, what excuse are you going to offer for preaching it, teaching it, extending it, perpetuating it?

"The Religion that is afraid of science dishonours God and commits suicide. It acknowledges that it is not equal to the whole of truth, that it legislates, tyrannizes over a village of God's empires but is not the immutable universal law. Every influx of atheism, of skepticism is thus made useful as a mercury pill assaulting and removing a diseased religion and making way for truth."
