Those who believe that they believe in God, but without passion in their hearts, without anguish in mind, without uncertainty, without doubt, without an element of despair even in their consolation, believe only in the God idea, not God Himself.

Some people will believe anything if you whisper it to them.

We need God, not in order to understand the why, but in order to feel and sustain the ultimate wherefore, to give a meaning to the universe.

True science teaches, above all, to doubt and to be ignorant.

A lot of good arguments are spoiled by some fool who knows what he is talking about.
