More quotes by 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
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
The survival value of intelligence is that it allows us to extinct a bad idea, before the idea extincts us.
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
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
No particular theory may ever be regarded as absolutely certain.... No scientific theory is sacrosanct.
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
Propose theories which can be criticized. Think about possible decisive falsifying experiments-crucial experiments. But do not give up your theories too easily-not, at any rate, before you have critically examined your criticism.
Karl Popper
Our knowledge can only be finite, while our ignorance must necessarily be infinite.
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
A theory is just a mathematical model to describe the observations.
Karl Popper
Thus science must begin with myths, and with the criticism of myths neither with the collection of observations, nor with the invention of experiments, but with the critical discussion of myths, and of magical techniques and practices.
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
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
Better our hypotheses die for our errors than ourselves.
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
True ignorance is not the absence of knowledge, but the refusal to acquire it.
Karl Popper
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
Now this principle of induction cannot be a purely logical truth like a tautology or an analytic statement. . . .
Karl Popper
There is no pure, disinterested, theory-free observation.
Karl Popper
