An animal that embarks on forming states without greatly restricting egoism will perish.

From all we have learnt about the structure of living matter, we must be prepared to find it working in a manner that cannot be reduced to the ordinary laws of physics. And that not on the ground that there is any 'new force' or what not, directing the behaviour of the single atoms within a living organism, but because the construction is different from anything we have yet tested in the physical laboratory.

If a man never contradicts himself, the reason must be that he virtually never says anything at all.

Whence come I and whither go I? That is the great unfathomable question. Science has no answer to it.

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. You are as firmly established, as invulnerable as she, indeed a thousand times firmer and more invulnerable. As surely as she will engulf you tomorrow, so surely will she bring you forth anew to the new striving and suffering. And not merely "some day." Now, today, every day she is bringing you forth, not once but thousands upon thousands of times, just as every day she engulfs you a thousand times over.

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.

We must not wait for things to come, believing that they are decided by irrescindable destiny. If we want it, we must do something about it.
