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.

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.

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.

Man's quest for knowledge is an expanding series whose limit is infinity, but philosophy seeks to attain that limit at one blow, by a short circuit providing the certainty of complete and inalterable truth. Science meanwhile advances at its gradual pace, often slowing to a crawl, and for periods it even walks in place, but eventually it reaches the various ultimate trenches dug by philosophical thought, and, quite heedless of the fact that it is not supposed to be able to cross those final barriers to the intellect, goes right on.

The horse respects and obeys man because its large eyes magnify everything, so man appears much larger than the horse itself.

Behind every glorious facade there is always hidden something ugly.

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.
