More quotes by Karl Popper
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
I have spoken to Einstein and he admitted to me that his theory was in fact no different from the one of Parmenides.
Karl Popper
Science may be described as the art of systematic over-simplification.
Karl Popper
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
Now this principle of induction cannot be a purely logical truth like a tautology or an analytic statement. . . .
Karl Popper
Reason like science, grows by way of mutual criticism the only possible way of planning its growth is to develop those institutions that safeguard. the freedom of thought
Karl Popper
We do not know. We can only guess.
Karl Popper
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
Science must begin with myths, and with the criticism of myths.
Karl Popper

(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
The conspiracy theory of society... comes from abandoning god and then asking: Who is in his place
Karl Popper
I remained a socialist for several years, even after my rejection of Marxism and if there could be such a thing as socialism combined with individual liberty, I would be a socialist still. For nothing could be better than living a modest, simple, and free life in an egalitarian society.
Karl Popper
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
Those who promise us paradise on earth never produced anything but a hell.
Karl Popper
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
We should therefore claim, in the name of tolerance, the right not to tolerate the intolerant.
Karl Popper
Man, some modern philosophers tell us, is alienated from his world: he is a stranger and afraid in a world he never made. Perhaps he is yet so are animals, and even plants. They too were born, long ago, into a physico-chemical world, a world they never made.
Karl Popper
There is no history, only histories.
Karl Popper
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
What really makes science grow is new ideas, including false ideas.
