More quotes by Karl Popper
Reason like science, grows by way of mutual criticism the only possible way of planning its growth is to develop those institutions that safeguard. the freedom of thought
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
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
What really makes science grow is new ideas, including false ideas.
Karl Popper
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
Science may be described as the art of systematic over-simplification.
Karl Popper
It is part of my thesis that all our knowledge grows only through the correcting of our mistakes.
Karl Popper
I see now more clearly than ever before that even our greatest troubles spring from something that is [as] admirable and sound as it is dangerous – from our impatience to better the lot of our fellows.
Karl Popper
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
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 survival value of intelligence is that it allows us to extinct a bad idea, before the idea extincts us.
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
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
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
A system is empirical or scientific only if it is capable of being tested by experience. These considerations suggest that not the verifiability but the falsifiability of a system is to be taken as a criterion of demarcation... It must be possible for an empirical or scientific system to be refuted by experience.
Karl Popper
We have become makers of our fate when we have ceased to pose as its prophets.
Karl Popper
It is not intuitive ease I am after, but rather a point of view which is sufficiently definite to clear up some difficulties, and to be criticized in rational terms. (Bohr's complementarity cannot be so criticized, I fear it can only be accepted or denounced - perhaps as being ad hoc, or as being irrational, or as being hopelessly vague.)
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
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
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
