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.
Interpretation
The quote suggests that theories can always be defended despite counter-evidence through additional hypotheses or reinterpretation.
Imre Lakatos, in his quote, points out a fundamental aspect of scientific theory: that no empirical result can definitively disprove a theory. Instead, when faced with contradictions, proponents of a theory can introduce supplementary hypotheses or reinterpret existing terms to defend their stance. This highlights the resilience and adaptability of scientific theories, emphasizing that they are often upheld not just by evidence, but also by the intellectual frameworks that surround them.
In practice
During a lecture on scientific method, this quote can be used to emphasize how theories are defended.
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.
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.
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.
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.
races condemned to 100 years of solitude did not have a second opportunity on earth.
Majorities and minorities cannot rightfully be taken at all into account in deciding questions of justice.
No one in this country need go hungry, and alleviating the problem is primarily a matter of readjusting our priorities. In both the government and the private sector, self-interest has displaced the ideal of community that made this country great. The old world view of "us, we, our" has been replaced by "I, me, mine." The reasons for this are manifold and complex, but at the end of the day, we need to remember that, if one of us is suffering needlessly, all of us are diminished.
Rather than love, than money, than fame, give me truth.
I grew up with four T.V. channels. If you missed a show, you missed it. You gotta wait a week for the next one. I'd mail-order books: take a quarter, get an envelope, send off for it and wait until it arrived. I grew up waiting for things.
Human nature is not black and white but black and grey.
