...the reason for [this age's] anxiety and unrest is because in one direction, 'truth' increases in scope and quantity - via science and technology - while in the other, certainty and confidence steadily decline. Our age is a master in developing truths while being wholly indifferent to certitude. It lacks confidence in the good.

The more men believe an idea to be true the greater the likelihood that the idea is mistaken. Those who are right usually stand alone.

I have attacked no one as not being a Christian, I have condemned no one.

Personality is only ripe when a man has made the truth his own.

Out of love for mankind, and out of despair at my embarrassing situation, seeing that I had accomplished nothing and was unable to make anything easier than it had already been made, and moved by a genuine interest in those who make everything easy, I conceived it as my task to create difficulties everywhere.

Humor (is) intrinsitc to Christianity.

Knowledge of the truth I may perhaps have attained to; happiness certainly not. What shall I do? Accomplish something in the world, men tell me. Shall I then publish my grief to the world, contribute one more proof for the wretchedness and misery of existence, perhaps discover a new flaw in human life, hitherto unnoticed? I might then reap the rare reward of becoming famous, like the man who discovered the spots on Jupiter. I prefer, however, to keep silent.
