More quotes by Karl Popper

Image
There can be no ultimate statements science: there can be no statements in science which can not be tested, and therefore none which cannot in principle be refuted, by falsifying some of the conclusions which can be deduced from them.
Karl Popper
Image
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
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
Science may be described as the art of systematic over-simplification.
Karl Popper
Image
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
Image
While differing widely in the various little bits we know, in our infinite ignorance we are all equal.
Karl Popper
Image
But it is certainly not possible to insist on one hand that the formalism is complete and to insist on the other hand that its application to 'the actual' actually demands a step which cannot be derived from it.
Karl Popper
Image
A theory is just a mathematical model to describe the observations.
Karl Popper
Image
There is no pure, disinterested, theory-free observation.
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
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
Image
Science must begin with myths, and with the criticism of myths.
Karl Popper
Image
We have become makers of our fate when we have ceased to pose as its prophets.
Karl Popper
Image
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
Image
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
Image
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
Image
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.
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
Image
It is a myth that the success of science in our time is mainly due to the huge amounts of money that have been spent on big machines. What really makes science grow is new ideas, including false ideas.
Karl Popper
Image
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
