Imre Lakatos Quotes
-
That sometimes clear ... and sometimes vague stuff ... which is ... mathematics.
→ -
Philosophy of science without history of science is empty; history of science without philosophy of science is blind.
→ -
Intellectual honesty consists in stating the precise conditions under which one will give up one's belief.
→ -
There is no falsification before the emergence of a better theory.
→ -
The history of mathematics, lacking the guidance of philosophy, [is] blind, while the philosophy of mathematics, turning its back on the most intriguing phenomena in the history of mathematics, is empty.
→ -
Indeed, this epistemological theory of the relation between theory and experiment differs sharply from the epistemological theory of naive falsificationism.
→ -
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.
→ -
In degenerating programmes, however, theories are fabricated only in order to accommodate known facts
→ -
It is not that we propose a theory and Nature may shout NO; rather, we propose a maze of theories, and Nature may shout INCONSISTENT.
→ -
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.
→ -
The positive heuristic of the programme saves the scientist from becoming confused by the ocean of anomalies.
→ -
Belief may be a regrettably unavoidable biological weakness to be kept under the control of criticism: but commitment is for Popper an outright crime.
→ -
The proving power of the intellect or the senses was questioned by the skeptics more than two thousand years ago; but they were browbeaten into confusion by the glory of Newtonian physics.
→ -
Blind commitment to a theory is not an intellectual virtue: it is an intellectual crime.
→ -
The great scientific achievements are research programmes which can be evaluated in terms of progressive and degenerative problemshifts; and scientific revolutions consist of one research programme superceding (overtaking in progress) another. This methodology offers a new rational reconstruction of science.
→ -
One may rationally stick to a degenerating research programme until it is overtaken by a rival and even after. What one must not do is to deny its poor public record... It is perfectly rational to play a risky game: what is irrational is to deceive oneself about the risk.
→ -
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.
→ -
Man's respect for knowledge is one of his most peculiar characteristics. Knowledge in Latin is scientia, and science came to be the name of the most respectable kind of knowledge.
→ -
Research programmes, besides their negative heuristic, are also characterized by their positive heuristic.
→ -
Mathematics does not grow through a monotonous increase of the number of indubitably established theorems but through the incessant improvement of guesses by speculation and criticism, by the logic of proofs and refutations.
→ -
No experimental result can ever kill a theory: any theory can be saved from counterinstances either by some auxiliary hypothesis or by a suitable reinterpretation of its terms.
→ -
The classical example of a successful research programme is Newton's gravitational theory: possibly the most successful research programme ever.
