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.

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

A theory that explains everything, explains nothing
Karl Popper

We have become makers of our fate when we have ceased to pose as its prophets.
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 and dangerous to extol freedom by telling people that they will certainly be all right once they are free. The most we can say of democracy or freedom is that they give our personal abilities a little more influence on our well-being.
Karl Popper
Image
There is no pure, disinterested, theory-free observation.
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.

If you can't say it simply and clearly, keep quiet, and keep working on it till you can.
Karl Popper
Image
The open society is one in which men have learned to be to some extent critical of taboos, and to base decisions on the authority of their own intelligence.
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
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

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

[To] interpret Parmenides as a Kant before Kant ... this is exactly what we must do.
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
It is not his possession of knowledge, of irrefutable truth, that makes the man of science, but his persistent and recklessly critical quest for truth.

The attempt to make heaven on earth invariably produces hell.

Better our hypotheses die for our errors than ourselves.
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
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.
