Our science is like a store filled with the most subtle intellectual devices for solving the most complex problems, and yet we are almost incapable of applying the elementary principles of rational thought.

In this world, only those people who have fallen to the lowest degree of humiliation, far below beggary, who are not just without any social consideration but are regarded by all as being deprived of that foremost human dignity, reason itself - only those people, in fact, are capable of telling the truth. All the others lie.

The need of truth is more sacred than any other need.

Evil being the root of mystery, pain is the root of knowledge.

Death. An instantaneous state, without past or future. Indispensable for entering eternity.

Human existence is so fragile a thing and exposed to such dangers that I cannot love without trembling.

The only way into truth is through one's own annihilation; through dwelling a long time in a state of extreme and total humiliation.
