More quotes by 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

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

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

A theory is just a mathematical model to describe the observations.
Karl Popper

Karl Popper

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
Every genuine test of a theory is an attempt to falsify it, or to refute it.
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
It is part of my thesis that all our knowledge grows only through the correcting of our mistakes.
Karl Popper
Image
If you can't say it simply and clearly, keep quiet, and keep working on it till you can.
Karl Popper
Image
Better our hypotheses die for our errors than ourselves.
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
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
Those who promise us paradise on earth never produced anything but a hell.

[To] interpret Parmenides as a Kant before Kant ... this is exactly what we must do.
