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

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

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

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