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.

Whenever we propose a solution to a problem, we ought to try as hard as we can to overthrow our solution, rather than defend it.
Karl Popper
Image
We never know what we are talking about.
Karl Popper
Image
[To] interpret Parmenides as a Kant before Kant ... this is exactly what we must do.
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
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
. . . it seems to me certain that more people are killed out of righteous stupidity than out of wickedness.
Karl Popper
Image
I have insisted that we must be tolerant. But I also believe that this tolerance has its limits. We must not trust those anti-humanitarian religions which not only preach destruction but act accordingly. For if we tolerate them, then we become ourselves responsible for for their deeds.
Karl Popper

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
Science may be described as the art of systematic over-simplification.
Karl Popper
Image
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
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
What really makes science grow is new ideas, including false ideas.
Karl Popper
Image
We do not know. We can only guess.
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
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
Image
Science must begin with myths, and with the criticism of myths.
Karl Popper
Image
Our knowledge can only be finite, while our ignorance must necessarily be infinite.
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
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
[The aim of science is] to explain what so far has taken to be an explicans, such as a law of nature. The task of empirical science constantly renews itself. We may go on forever, proceeding to explanations of a higher and higher universality.
Karl Popper
