Blind commitment to a theory is not an intellectual virtue: it is an intellectual crime.

There is no falsification before the emergence of a better theory.

Philosophy of science without history of science is empty; history of science without philosophy of science is blind.

Indeed, this epistemological theory of the relation between theory and experiment differs sharply from the epistemological theory of naive falsificationism.

The classical example of a successful research programme is Newton's gravitational theory: possibly the most successful research programme ever.

If even in science there is no a way of judging a theory but by assessing the number, faith and vocal energy of its supporters, then this must be even more so in the social sciences: truth lies in power.
