For myself, I like a universe that, includes much that is unknown and, at the same time, much that is knowable. A universe in which everything is known would be static and dull, as boring as the heaven of some weak-minded theologians. A universe that is unknowable is no fit place for a thinking being. The ideal universe for us is one very much like the universe we inhabit. And I would guess that this is not really much of a coincidence.

Only by a continual effort can I create. My tendency is to drift toward immobility. My deepest, surest inclination lies in silence and the daily routine…But I know that I stand erect through that very effort and that if I ceased to believe in it for a single moment I should roll over the precipice. This is how I avoid illness and renunciation, raising my head with all my strength to breathe and to conquer. This is my way of despairing and this is my way of curing myself.
