We never know what we are talking about.
Karl Popper
Image
No book can ever be finished. While working on it we learn just enough to find it immature the moment we turn away from it
Karl Popper
Image
We must plan for freedom, and not only for security, if for no other reason than only freedom can make security more secure.
Karl Popper
Image
With regards to political enemies Plato had a kill-and-banish principle. ... In interpreting it , modern-day Platonists are clearly disturbed by it, even as they make elaborate attempts to defend Plato.
Karl Popper
Image
Those who promise us paradise on earth never produced anything but a hell.
Karl Popper
Image
The future is always present, as a promise, a lure and a temptation.
Karl Popper
Image
Historically speaking all - or very nearly all - scientific theories originate from myths.
Karl Popper
Image
Thus science must begin with myths, and with the criticism of myths neither with the collection of observations, nor with the invention of experiments, but with the critical discussion of myths, and of magical techniques and practices.
Karl Popper
Image
The more we learn about the world, and the deeper our learning, the more conscious, specific, and articulate will be our knowledge of what we do not know, our knowledge of our ignorance
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
Unlimited tolerance must lead to the disappearance of tolerance. If we extend unlimited tolerance even to those who are intolerant, if we are not prepared to defend a tolerant society, then the tolerant will be destroyed, and tolerance with them. 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
No particular theory may ever be regarded as absolutely certain.... No scientific theory is sacrosanct.
Karl Popper
Image
Propose theories which can be criticized. Think about possible decisive falsifying experiments-crucial experiments. But do not give up your theories too easily-not, at any rate, before you have critically examined your criticism.
Karl Popper
Image
We have become makers of our fate when we have ceased to pose as its prophets.
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
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
Image
Good tests kill flawed theories we remain alive to guess again.
Karl Popper
Image
Ignorance is not a simple lack of knowledge but an active aversion to knowledge, the refusal to know, issuing from cowardice, pride, or laziness of mind.
Karl Popper
