We have the right not to tolerate the intolerant. We should tolerate even them whenever we can do so without running a great risk but the risk may become so great that we cannot allow ourselves the luxury.
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

Now this principle of induction cannot be a purely logical truth like a tautology or an analytic statement. . . .
Karl Popper
Image
Science must begin with myths, and with the criticism of myths.
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

Our knowledge can only be finite, while our ignorance must necessarily be infinite.
Karl Popper

No particular theory may ever be regarded as absolutely certain.... No scientific theory is sacrosanct.
Karl Popper

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

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

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.

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
Image
A theory is just a mathematical model to describe the observations.
Karl Popper
Image
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
Image
The question is not how to get good people to rule THE QUESTION IS: HOW TO STOP THE POWERFUL from doing as much damage as they can to us.
Karl Popper
Image
What really makes science grow is new ideas, including false ideas.
Karl Popper

[To] interpret Parmenides as a Kant before Kant ... this is exactly what we must do.
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
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
Every genuine test of a theory is an attempt to falsify it, or to refute it.
Karl Popper
Image
But some of these theories are so bold that they can clash with reality: they are the testable theories of science. And when they clash, then we know that there is a reality something that can inform us that our ideas are mistaken.
Karl Popper
