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
We never know what we are talking about.
Karl Popper
Image
The attempt to make heaven on earth invariably produces hell.
Karl Popper
Image
The future is always present, as a promise, a lure and a temptation.
Karl Popper
Image
We do not know. We can only guess.
Karl Popper
Image
The war of ideas is a Greek invention. It is one of the most important inventions ever made. Indeed, the possibility of fighting with with words and ideas instead of fighting with swords is the very basis of our civilization, and especially of all its legal and parliamentary institutions.
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
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
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
We have the right not to tolerate the intolerant. We should tolerate even them whenever we can do so without running a great risk but the risk may become so great that we cannot allow ourselves the luxury.
Karl Popper
Image
The question is not how to get good people to rule THE QUESTION IS: HOW TO STOP THE POWERFUL from doing as much damage as they can to us.
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
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
Historically speaking all - or very nearly all - scientific theories originate from myths.
Karl Popper
Image
A system is empirical or scientific only if it is capable of being tested by experience. These considerations suggest that not the verifiability but the falsifiability of a system is to be taken as a criterion of demarcation... It must be possible for an empirical or scientific system to be refuted by experience.
Karl Popper
Image
We must plan for freedom, and not only for security, if for no other reason than only freedom can make security more secure.
Karl Popper
Image
The use of violence is justified only under a tyranny which makes reforms without violence impossible, and should have only one aim, that is, to bring about a state of affairs which makes reforms without violence possible.
Karl Popper

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