The only knowledge which satisfies us is one which is subject to no external standards but springs from the inner life of the personality.

The realms of life are many. For each one, special sciences develop. But life itself is a unity, and the more deeply the sciences try to penetrate into their separate realms, the more they withdraw themselves from the vision of the world as a living whole.

A truth which comes to us from outside always bears the stamp of uncertainty. We can believe only what appears to each one of us in our own hearts as truth.
