Einstein's results again turned the tables and now very few philosophers or scientists still think that scientific knowledge is, or can be, proven knowledge.

That sometimes clear ... and sometimes vague stuff ... which is ... mathematics.

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.

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

Intellectual honesty consists in stating the precise conditions under which one will give up one's belief.

The positive heuristic of the programme saves the scientist from becoming confused by the ocean of anomalies.

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