The game of science is, in principle, without end. He who decides one day that scientific statements do not call for any further test, and that they can be regarded as finally verified, retires from the game.

Science may be described as the art of systematic over-simplification.

Contrary to the outstanding work of art, outstanding theory is susceptible to improvements.

Plato felt that a complete reconstruction of society's political program was needed.

There is no pure, disinterested, theory-free observation.

My thesis is that what we call 'science' is differentiated from the older myths not by being something distinct from a myth, but by being accompanied by a second-order tradition-that of critically discussing the myth. ... In a certain sense, science is myth-making just as religion is.

Whenever we propose a solution to a problem, we ought to try as hard as we can to overthrow our solution, rather than defend it.
