Every noble action is selfish. Some selfish actions are nobler than others. But they are all selfish. And as such there can be no action purely noble anyway. Even the nobility in God's great philosophical intentions is bounded by his vanity.

If knowledge is my God, doubt would be my religion.

How miserable a solipsist is! It is rather senseless for him to even assert his belief in solipsism, for, on the one hand, if his belief is false it is like committing intellectual suicide, and, on the other hand, if his belief is true it is an act of intellectual insanity.

God created the world to be praised on the subtle nature of his existence.

What can be greater to life than to understand its meaning.

God is the only evil. His vanity made him the devil.
