More quotes by Karl Popper
I have spoken to Einstein and he admitted to me that his theory was in fact no different from the one of Parmenides.
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
A theory that explains everything, explains nothing
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
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
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
There is no pure, disinterested, theory-free observation.
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
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
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
It is part of my thesis that all our knowledge grows only through the correcting of our mistakes.
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
My thesis is that what we call 'science' is differentiated from the older myths not by being something distinct from a myth, but by being accompanied by a second-order tradition-that of critically discussing the myth. ... In a certain sense, science is myth-making just as religion is.
Karl Popper
Those who promise us paradise on earth never produced anything but a hell.
Karl Popper
A theory is just a mathematical model to describe the observations.
Karl Popper
A theory which is not refutable by any conceivable event is non-scientific. Irrefutability is not a virtue of a theory (as people often think) but a vice.
Karl Popper
No particular theory may ever be regarded as absolutely certain.... No scientific theory is sacrosanct.
Karl Popper
The future is always present, as a promise, a lure and a temptation.
Karl Popper
Criticism of my alleged views was widespread and highly successful. I have yet to meet a criticism of my views.
Karl Popper
The history of science is everywhere speculative. It is a marvelous hiatory. It makes you proud to be a human being.
