One is proud to worship when he cannot be an idol.

After coming into contact with a religious man I always feel I must wash my hands.

When we have a great goal we are superior even to justice, not merely to our deeds and our judges.

Yet for all that, there is nothing in me of a founder of a religion--religions are affairs of the rabble; I find it necessary to wash my hands after I have come into contact with religious people.

You highest men whom I have ever seen! This is my suspicion about you and my secret laughter: I guess that you would call my superman--a devil!

Growth in wisdom can be measured precisely by decline in bile.

Modern science has as its object as little pain as possible, as long a life as possible - hence a sort of eternal blessedness, but of a very limited kind in comparison with the promises of religion.
