Those who promise us paradise on earth never produced anything but a hell.
Karl Popper
Image
Historically speaking all - or very nearly all - scientific theories originate from myths.
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
What really makes science grow is new ideas, including false ideas.
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
The survival value of intelligence is that it allows us to extinct a bad idea, before the idea extincts us.
Karl Popper
Image
We should therefore claim, in the name of tolerance, the right not to tolerate the intolerant.
Karl Popper
Image
A theory is just a mathematical model to describe the observations.
Karl Popper
Image
With regards to political enemies Plato had a kill-and-banish principle. ... In interpreting it , modern-day Platonists are clearly disturbed by it, even as they make elaborate attempts to defend Plato.
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
Now this principle of induction cannot be a purely logical truth like a tautology or an analytic statement. . . .
Karl Popper
Image
We never know what we are talking about.
Karl Popper
Image
The fundamental thing about human languages is that they can and should be used to describe something and this something is, somehow, the world. To be constantly and almost exclusively interested in the medium - in spectacle-cleaning - is a result of a philosophical mistake.
Karl Popper
Image
To give a causal explanation of an event means to deduce a statement which describes it, using as premises of the deduction one or more universal laws, together with certain singular statements, the initial conditions ... We have thus two different kinds of statement, both of which are necessary ingredients of a complete causal explanation.
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
. . . it seems to me certain that more people are killed out of righteous stupidity than out of wickedness.
Karl Popper
Image
Better our hypotheses die for our errors than ourselves.
Karl Popper
Image
It is part of my thesis that all our knowledge grows only through the correcting of our mistakes.
Karl Popper
Image
The attempt to make heaven on earth invariably produces hell.
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.
