The material which a scientist actually has at his disposal, his laws, his experimental results, his mathematical techniques, his epistemological prejudices, his attitude towards the absurd consequences of the theories which he accepts, is indeterminate in many ways, ambiguous, and never fully separated from the historical background . This material is always contaminated by principles which he does not know and which, if known, would be extremely hard to test.

I do not see why I should be polite to tyrants, who slobber of humanitarianism and think only of their own petty interests.

Human paint, produce films and videos; they dance, dream and make music; they engage in political action, exchange goods, perform rituals, build houses start wars, act in plays, try to please patrons- and so on... They contain patterns, press the practitioners to "conform" and in this way mold their thought, their perception, their actions, and their discriminative abilities.

Those who violate the rules of a language do not enter new territory; they leave the domain of meaningful discourse. Even facts in these circumstances dissolve, because they are shaped by the language and subjected to its limitations.

First-world science is one science among many; by claiming to be more it ceases to be an instrument of research and turns into a (political) pressure group.

Arguments hardly affect the faithful- their beliefs have an entirely different foundation.

Humane science must be adapted to the requirements of a balanced and rewarding life.
