Karl Popper
What really makes science grow is new ideas, including false ideas.
Karl Popper

Karl Popper
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
Criticism of my alleged views was widespread and highly successful. I have yet to meet a criticism of my views.
Karl Popper
Better our hypotheses die for our errors than ourselves.
Karl Popper
It is wrong to think that belief in freedom always leads to victory we must always be prepared for it to lead to defeat. If we choose freedom, then we must be prepared to perish along with it.
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
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
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
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
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
