The worst insult I can inflict on life is that I do not reflect on its meaning.

Life is a question asked by God about the way he exists.

If I am convinced that I will procure the profoundest idea only by undergoing the profoundest pain, I shall beg for strength to endure that pain.

Any systematic body of knowledge is science. The more systematic the body of knowledge is the more scientific it is.

An idealistic lover is a blind lover, and therefore a true lover; a pragmatic lover is a sighted lover, and therefore a false lover.

The word philosophy, as distinguished from science, is misleading, for it implies that what philosophy contains is impossible to be a systematic body of knowledge and what science contains is certain or proved.

Man is an appearance, God is a reality.
