More quotes by Karl Popper
The old scientific ideal of episteme - of absolutely certain, demonstrable knowledge - has proved to be an idol. The demand for scientific objectivity makes it inevitable that every scientific statement must remain tentative for ever.
Karl Popper
[To] interpret Parmenides as a Kant before Kant ... this is exactly what we must do.
Karl Popper
The survival value of intelligence is that it allows us to extinct a bad idea, before the idea extincts us.
Karl Popper
A theory that explains everything, explains nothing
Karl Popper
The genuine rationalist does not think that he or anyone else is in possession of the truth nor does he think that mere criticism as such helps us achieve new ideas. But he does think that, in the sphere of ideas, only critical discussion can help us sort the wheat from the chaff.
Karl Popper
It is a myth that the success of science in our time is mainly due to the huge amounts of money that have been spent on big machines. What really makes science grow is new ideas, including false ideas.
Karl Popper
Good tests kill flawed theories we remain alive to guess again.
Karl Popper
There is no history, only histories.
Karl Popper
In my view, aiming at simplicity and lucidity is a moral duty of all intellectuals: lack of clarity is a sin, and pretentiousness is a crime.
Karl Popper
The best thing that can happen to a human being us to find a problem, to fall in love with that problem, and to live trying to solve that problem, unless another problem even more lovable appears.
Karl Popper
The defence of democracy must consist in making anti-democratic experiences too costly for those who try them much more costly than a democratic compromise
Karl Popper
The use of violence is justified only under a tyranny which makes reforms without violence impossible, and should have only one aim, that is, to bring about a state of affairs which makes reforms without violence possible.
Karl Popper
A system is empirical or scientific only if it is capable of being tested by experience. These considerations suggest that not the verifiability but the falsifiability of a system is to be taken as a criterion of demarcation... It must be possible for an empirical or scientific system to be refuted by experience.
Karl Popper
I remained a socialist for several years, even after my rejection of Marxism and if there could be such a thing as socialism combined with individual liberty, I would be a socialist still. For nothing could be better than living a modest, simple, and free life in an egalitarian society.
Karl Popper
It is not his possession of knowledge, of irrefutable truth, that makes the man of science, but his persistent and recklessly critical quest for truth.
Karl Popper
We do not know. We can only guess.
Karl Popper
Some scientists find, or so it seems, that they get their best ideas when smoking others by drinking coffee or whisky. Thus there is no reason why I should not admit that some may get their ideas by observing, or by repeating observations.
Karl Popper
Now this principle of induction cannot be a purely logical truth like a tautology or an analytic statement. . . .
Karl Popper
no matter how many instances of white swans we may have observed, this does not justify the conclusion that all swans are white.
Karl Popper
But it is certainly not possible to insist on one hand that the formalism is complete and to insist on the other hand that its application to 'the actual' actually demands a step which cannot be derived from it.
Karl Popper
