The first 90% of the job takes 90% of the time. The remaining 10% of the job requires another 90% of the time. The first condition of immortality is death.

Of the two powers, the two categories that take possession of us when we enter the world (from where?), space is by far the less mysterious. It, too, undergoes transformations. Time, on the other hand, is a hostile element, truly treacherous, I would even say against human nature.

Psychoanalysis provides truth in an infantile, that is, a schoolboy fashion: we learn from it, roughly and hurriedly, things that scandalize us and thereby command our attention. It sometimes happens, and such is the case here, that a simplification touching upon the truth, but cheaply, is of no more value than a lie. Once again we are shown the demon and the angel, the beast and the god locked in Manichean embrace, and once again man has been pronounced, by himself, not culpable.

Each civilization may choose one of two roads to travel, that is, either fret itself to death, or pet itself to death. And in the course of doing one or the other, it eats its way into the Universe, turning cinders and flinders of stars into toilet seats, pegs, gears, cigarette holders and pillowcases, and it does this because, unable to fathom the Universe, it seeks to change that Fathomlessness into Something Fathomable.

The war of good and evil present in all religions does not always end, in every faith, with the victory of good, but in every one it establishes a clear order of existence. The sacred as well as the profane rests on that universal order.

My pessimism (which, by the way, is far from absolute) originated with my despair in the lack of perfection to be found in human nature. I was attempting in my successive books to show the inevitable handicap of the human condition.

We didn't know each other well. I never had the time. Now I see that it doesn't make any difference. The ones who hurry and the ones who take their time all end up in the same place. Just don't have any regrets. No regrets.
