It is the theory that decides what can be observed.

A theory is something nobody believes, except the person who made it. An experiment is something everybody believes, except the person who made it.

A desk, some pads, a pencil, and a large basket -- to hold all of mu mistakes.

I cannot conceive of a personal God who would directly influence the actions of individuals, or would directly sit in judgment on creatures of his own creation. I cannot do this in spite of the fact that mechanistic causality has, to a certain extent, been placed in doubt by modern science. My religiosity consists in a humble admiration of the infinitely superior spirit that reveals itself in the little that we, with our weak and transitory understanding, can comprehend of reality. Morality is of the highest importance - but for us, not for God.
