Science is perhaps the only human activity in which errors are systematically criticized and, in time, corrected.

All life is problem solving

There is an almost universal tendency, perhaps an inborn tendency, to suspect the good faith of a man who holds opinions that differ from our own opinions. It obviously endangers the freedom and the objectivity of our discussion if we attack a person instead of attacking an opinion or, more precisely, a theory.

True ignorance is not the absence of knowledge, but the refusal to acquire it.

In my view, aiming at simplicity and lucidity is a moral duty of all intellectuals: lack of clarity is a sin, and pretentiousness is a crime.

It is not his possession of knowledge, of irrefutable truth, that makes the man of science, but his persistent and recklessly critical quest for truth.

Science is perhaps the only human activity in which errors are systematically criticized and, in time, corrected.
