Imre Lakatos — Hungarian Philosopher born on November 09, 1922, died on February 02, 1974

Imre Lakatos was a Hungarian philosopher of mathematics and science, known for his thesis of the fallibility of mathematics and its 'methodology of proofs and refutations' in its pre-axiomatic stages of development, and also for introducing the concept of the 'research programme' in his methodology of scientific research programmes...

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.
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.
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.
