Our knowledge can only be finite, while our ignorance must necessarily be infinite.
Karl Popper
Image
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 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
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

If you can't say it simply and clearly, keep quiet, and keep working on it till you can.
Karl Popper

The history of science is everywhere speculative. It is a marvelous hiatory. It makes you proud to be a human being.
Karl Popper
Image
No particular theory may ever be regarded as absolutely certain.... No scientific theory is sacrosanct.
Karl Popper
Image
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.

I have spoken to Einstein and he admitted to me that his theory was in fact no different from the one of Parmenides.

What really makes science grow is new ideas, including false ideas.
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
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
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
Image
The fundamental thing about human languages is that they can and should be used to describe something and this something is, somehow, the world. To be constantly and almost exclusively interested in the medium - in spectacle-cleaning - is a result of a philosophical mistake.
Karl Popper
Image
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
Image
There is no history, only histories.
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
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

Criticism of my alleged views was widespread and highly successful. I have yet to meet a criticism of my views.
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
