More quotes by Karl Popper
The old scientific ideal of episteme - of absolutely certain, demonstrable knowledge - has proved to be an idol. The demand for scientific objectivity makes it inevitable that every scientific statement must remain tentative for ever.
Karl Popper
Good tests kill flawed theories we remain alive to guess again.
Karl Popper
The open society is one in which men have learned to be to some extent critical of taboos, and to base decisions on the authority of their own intelligence.
Karl Popper
What really makes science grow is new ideas, including false ideas.
Karl Popper
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.
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
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
The best thing that can happen to a human being us to find a problem, to fall in love with that problem, and to live trying to solve that problem, unless another problem even more lovable appears.
Karl Popper
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
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
The fundamental thing about human languages is that they can and should be used to describe something and this something is, somehow, the world. To be constantly and almost exclusively interested in the medium - in spectacle-cleaning - is a result of a philosophical mistake.
Karl Popper
Every genuine test of a theory is an attempt to falsify it, or to refute it.
Karl Popper
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
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
The future is always present, as a promise, a lure and a temptation.
Karl Popper
While differing widely in the various little bits we know, in our infinite ignorance we are all equal.
Karl Popper
The conspiracy theory of society... comes from abandoning god and then asking: Who is in his place
Karl Popper
To give a causal explanation of an event means to deduce a statement which describes it, using as premises of the deduction one or more universal laws, together with certain singular statements, the initial conditions ... We have thus two different kinds of statement, both of which are necessary ingredients of a complete causal explanation.
Karl Popper
Our knowledge can only be finite, while our ignorance must necessarily be infinite.
Karl Popper
It is wrong and dangerous to extol freedom by telling people that they will certainly be all right once they are free. The most we can say of democracy or freedom is that they give our personal abilities a little more influence on our well-being.
Karl Popper
