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
There is no history, only histories.
Karl Popper
It is wrong to think that belief in freedom always leads to victory we must always be prepared for it to lead to defeat. If we choose freedom, then we must be prepared to perish along with it.
Karl Popper
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
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
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
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
We should therefore claim, in the name of tolerance, the right not to tolerate the intolerant.
Karl Popper
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
The future is always present, as a promise, a lure and a temptation.
Karl Popper
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
. . . it seems to me certain that more people are killed out of righteous stupidity than out of wickedness.
Karl Popper
The war of ideas is a Greek invention. It is one of the most important inventions ever made. Indeed, the possibility of fighting with with words and ideas instead of fighting with swords is the very basis of our civilization, and especially of all its legal and parliamentary institutions.
Karl Popper
The survival value of intelligence is that it allows us to extinct a bad idea, before the idea extincts us.
Karl Popper
The conspiracy theory of society... comes from abandoning god and then asking: Who is in his place
Karl Popper
Now this principle of induction cannot be a purely logical truth like a tautology or an analytic statement. . . .
Karl Popper
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
It is part of my thesis that all our knowledge grows only through the correcting of our mistakes.
Karl Popper
Our knowledge can only be finite, while our ignorance must necessarily be infinite.
Karl Popper
A theory is just a mathematical model to describe the observations.
Karl Popper
[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
