“How much truth can a spirit bear, how much truth can a spirit dare? ... that became for me more and more the real measure of value.”

“Neither can such a doctrine argue: it simply does not understand that other doctrines exist, can exist, it simply does not know how to imagine an opinion contrary to its own”

“The daring venture, the prolonged distrust, the cruel Nay, the tedium, the cutting-into-the-quick—how seldom do THESE come together! Out of such seed, however—is truth produced!”

“This woman is beautiful and clever: but how much cleverer she would have become if she were not beautiful!”
