Research programmes, besides their negative heuristic, are also characterized by their positive heuristic.

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

It would be wrong to assume that one must stay with a research programme until it has exhausted all its heuristic power, that one must not introduce a rival programme before everybody agrees that the point of degeneration has probably been reached.

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

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

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.

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

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

It takes but one positive thought when given a chance to survive and thrive to overpower an entire army of negative thoughts.

Kant introduced the concept of the negative into philosophy. Would it not also be worthwhile to try to introduce the concept of the positive into philosophy?

An investigator starts research in a new field with faith, a foggy idea, and a few wild experiments. Eventually the interplay of negative and positive results guides the work. By the time the research is completed, he or she knows how it should have been started and conducted.

I do my job in Type O Negative.
