Criticism of my alleged views was widespread and highly successful. I have yet to meet a criticism of my views.
Karl Popper
Image
[To] interpret Parmenides as a Kant before Kant ... this is exactly what we must do.
Karl Popper
Image
The more we learn about the world, and the deeper our learning, the more conscious, specific, and articulate will be our knowledge of what we do not know, our knowledge of our ignorance
Karl Popper
Image
The survival value of intelligence is that it allows us to extinct a bad idea, before the idea extincts us.
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
The conspiracy theory of society... comes from abandoning god and then asking: Who is in his place
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
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
But it is certainly not possible to insist on one hand that the formalism is complete and to insist on the other hand that its application to 'the actual' actually demands a step which cannot be derived from it.
Karl Popper
Image
We do not know. We can only guess.
Karl Popper
Image
It is not intuitive ease I am after, but rather a point of view which is sufficiently definite to clear up some difficulties, and to be criticized in rational terms. (Bohr's complementarity cannot be so criticized, I fear it can only be accepted or denounced - perhaps as being ad hoc, or as being irrational, or as being hopelessly vague.)
Karl Popper
Image
A theory is just a mathematical model to describe the observations.
Karl Popper
Image
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
Image
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
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
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
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
We never know what we are talking about.
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

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
