Rational thinking which is free from assumptions ends therefore in mysticism. To relate oneself in the spirit of reverence for life to the multiform manifestations of the will-to-live which together constitute the world is ethical mysticism.

Then we see him as he really is.

No one can give a definition of the soul. But we know what it feels like.
