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

Image
The future is always present, as a promise, a lure and a temptation.
Karl Popper
Image
It is a myth that the success of science in our time is mainly due to the huge amounts of money that have been spent on big machines. What really makes science grow is new ideas, including false ideas.
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
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
Image
While differing widely in the various little bits we know, in our infinite ignorance we are all equal.
Karl Popper
Image
A theory that explains everything, explains nothing
Karl Popper
Image
I see now more clearly than ever before that even our greatest troubles spring from something that is [as] admirable and sound as it is dangerous – from our impatience to better the lot of our fellows.
Karl Popper
Image
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
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
Image
Ignorance is not a simple lack of knowledge but an active aversion to knowledge, the refusal to know, issuing from cowardice, pride, or laziness of mind.
Karl Popper
Image
The best thing that can happen to a human being us to find a problem, to fall in love with that problem, and to live trying to solve that problem, unless another problem even more lovable appears.
Karl Popper
Image
no matter how many instances of white swans we may have observed, this does not justify the conclusion that all swans are white.
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
There is no history, only histories.
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.
Karl Popper
Image
It is part of my thesis that all our knowledge grows only through the correcting of our mistakes.
Karl Popper
Image
We never know what we are talking about.
Karl Popper
Image
The influence (for good or ill) of Plato's work is immeasurable. Western thought, one might say, has been Platonic or anti-Platonic, but hardly ever non-Platonic.
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
We do not choose political freedom because it promises us this or that. We choose it because it makes possible the only dignified form of human coexistence, the only form in which we can be fully responsible for ourselves. Whether we realize its possibilities depends on all kinds of things — and above all on ourselves.
Karl Popper
