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
Image
If you can't say it simply and clearly, keep quiet, and keep working on it till you can.
Karl Popper
Image
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
Image
There is no history, only histories.
Karl Popper
Image
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
Image
No particular theory may ever be regarded as absolutely certain.... No scientific theory is sacrosanct.
Karl Popper

Those who promise us paradise on earth never produced anything but a hell.
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.

Better our hypotheses die for our errors than ourselves.

The war of ideas is a Greek invention. It is one of the most important inventions ever made. Indeed, the possibility of fighting with with words and ideas instead of fighting with swords is the very basis of our civilization, and especially of all its legal and parliamentary institutions.
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
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
Image
I remained a socialist for several years, even after my rejection of Marxism and if there could be such a thing as socialism combined with individual liberty, I would be a socialist still. For nothing could be better than living a modest, simple, and free life in an egalitarian society.
Karl Popper
Image
Our knowledge can only be finite, while our ignorance must necessarily be infinite.
Karl Popper
Image
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
Image
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
Image
If you know that things are bound to happen whatever you do, then you may feel free to give up the fight against them.
Karl Popper
Image
[To] interpret Parmenides as a Kant before Kant ... this is exactly what we must do.
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

True ignorance is not the absence of knowledge, but the refusal to acquire it.
