Science cannot tell us a word about why music delights us, of why and how an old song can move us to tears.

This life of yours which you are living is not merely a piece of this entire existence, but in a certain sense the whole... Thus you can throw yourself flat on the ground, stretched out upon mother earth, with the certain conviction that you are one with her and she with you.

Consciousness is a singular for which there is no plural.

If all this damned quantum jumping were really here to stay, I should be sorry, I should be sorry I ever got involved with quantum theory.
