Quote

The game of science is, in principle, without end. He who decides one day that scientific statements do not call for any further test, and that they can be regarded as finally verified, retires from the game.

More quotes by Karl Popper

Image
The survival value of intelligence is that it allows us to extinct a bad idea, before the idea extincts us.
Karl Popper
Image
Man, some modern philosophers tell us, is alienated from his world: he is a stranger and afraid in a world he never made. Perhaps he is yet so are animals, and even plants. They too were born, long ago, into a physico-chemical world, a world they never made.
Karl Popper
Image
The influence (for good or ill) of Plato's work is immeasurable. Western thought, one might say, has been Platonic or anti-Platonic, but hardly ever non-Platonic.
Karl Popper
Image
We know a great deal, but our ignorance is sobering and boundless. With each step forward, with each problem which we solve, we not only discover new and unsolved problems, but we also discover that where we believed that we were standing on firm and safe ground, all things are, in truth, insecure and in a state of flux.
Karl Popper
Image
We have become makers of our fate when we have ceased to pose as its prophets.
Karl Popper
Image
We do not choose political freedom because it promises us this or that. We choose it because it makes possible the only dignified form of human coexistence, the only form in which we can be fully responsible for ourselves. Whether we realize its possibilities depends on all kinds of things — and above all on ourselves.
Karl Popper
Image
Our knowledge can only be finite, while our ignorance must necessarily be infinite.
Karl Popper
Image
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
Image
A theory which is not refutable by any conceivable event is non-scientific. Irrefutability is not a virtue of a theory (as people often think) but a vice.
Karl Popper
Image
I may be wrong and you may be right, and by an effort, we may get nearer to the truth
Karl Popper
Image
Those who promise us paradise on earth never produced anything but a hell.
Karl Popper
Image
I have spoken to Einstein and he admitted to me that his theory was in fact no different from the one of Parmenides.
Karl Popper
Image
We should therefore claim, in the name of tolerance, the right not to tolerate the intolerant.
Karl Popper
Image
If you can't say it simply and clearly, keep quiet, and keep working on it till you can.
Karl Popper
Image
What really makes science grow is new ideas, including false ideas.
Karl Popper
Image
We never know what we are talking about.
Karl Popper
Image
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
Image
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

There is no history, only histories.
Karl Popper

The future is always present, as a promise, a lure and a temptation.
Karl Popper
