More quotes by Karl Popper

Image
A theory is just a mathematical model to describe the observations.
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
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
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
The survival value of intelligence is that it allows us to extinct a bad idea, before the idea extincts us.
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
There is no pure, disinterested, theory-free observation.
Karl Popper
Image
We never know what we are talking about.
Karl Popper
Image
No particular theory may ever be regarded as absolutely certain.... No scientific theory is sacrosanct.
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
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
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
Our knowledge can only be finite, while our ignorance must necessarily be infinite.
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 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
. . . it seems to me certain that more people are killed out of righteous stupidity than out of wickedness.
Karl Popper
Image
Simple statements are to be prized more highly than less simple ones because they tell us more because their empirical content is greater and because they are better testable.
Karl Popper
Image
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.

We should therefore claim, in the name of tolerance, the right not to tolerate the intolerant.

We do not know. We can only guess.
