Science is turning into a monastery for the Order of Capitulant Friars. Logical calculus is supposed to supersede man as moralist. We submit to the blackmail of the 'superior knowledge' that has the temerity to assert that nuclear war can be, by derivation, a good thing, because this follows from simple arithmetic.

Skepticism is like a microscope whose magnification is constantly increased: the sharp image that one begins with finally dissolves, because it is not possible to see ultimate things: their existence is only to be inferred.

To torture a man you have to know his pleasures.

Psychoanalytic doctrine reveals the pig in man, a pig saddled with a conscience; the disastrous result is that the pig is uncomfortable beneath that pious rider, and the rider fares no better in the situation, since his endeavor is not only to tame the pig, but also to render it invisible.

Giese was an unemotional man, but then in the study of Solaris emotion is a hindrance to the explorer. Imagination and premature theorizing are positive disadvantages in approaching a planet where-as has become clear-anything is possible...

Mathematics never reveals man to the degree, never expresses him in the way, that any other field of human endeavour does: the extent of the negation of man's corporeal self that mathematics achieves cannot be compared with anything. Whoever is interested in this subject I refer to my articles. Here I will say only that the world injected its patterns into human language at the very inception of that language; mathematics sleeps in every utterance, and can only be discovered, never invented.

Every stink that fights the ventilator thinks it is Don Quixote.
