If you can't say it simply and clearly, keep quiet, and keep working on it till you can.
Karl Popper
Image
We know a great deal, but our ignorance is sobering and boundless. With each step forward, with each problem which we solve, we not only discover new and unsolved problems, but we also discover that where we believed that we were standing on firm and safe ground, all things are, in truth, insecure and in a state of flux.
Karl Popper
Image
Our knowledge can only be finite, while our ignorance must necessarily be infinite.
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
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
Those who promise us paradise on earth never produced anything but a hell.
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
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
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
There is no history, only histories.
Karl Popper
Image
Science must begin with myths, and with the criticism of myths.
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
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
While differing widely in the various little bits we know, in our infinite ignorance we are all equal.
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
A theory is just a mathematical model to describe the observations.
Karl Popper
Image
The history of science is everywhere speculative. It is a marvelous hiatory. It makes you proud to be a human being.
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
We have become makers of our fate when we have ceased to pose as its prophets.
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.
