Karl Popper quotes about
ideas machines bigs
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.
funny art crazy
Science may be described as the art of systematic over-simplification.
fate prophet makers
We have become makers of our fate when we have ceased to pose as its prophets.
mistake evolution speed
Our aim must be to make our successive mistakes as quickly as possible. To speed up evolution.
research evolution metaphysical
I have come to the conclusion that Darwinism is not a testable scientific theory, but a metaphysical research programme...
objectivity subjectivity knows
We do not know. We can only guess.
long decision tolerance
The moral decisions of others should be treated with respect, as long as such decisions do not conflict with the principle of tolerance.
mean men wisest-man
We should realize that, if [Socrates] demanded that the wisest men should rule, he clearly stressed that he did not mean the learned men; in fact, he was skeptical of all professional learnedness, whether it was that of the philosophers or of the learned men of his own generation, the Sophists. The wisdom he meant was of a different kind. It was simply the realization: how little do I know! Those who did not know this, he taught, knew nothing at all. This is the true scientific spirit.
views simplicity moral
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.
hayek i-have-learned thinker
I have learned more from Hayek than from any other living thinker, except perhaps Alfred Tarski - but not even excepting Russell.
powerful people damage
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.
philosophy philosophical character
Philosophy is a necessary activity because we, all of us, take a great number of things for granted, and many of these assumptions are of a philosophical character; we act on them in private life, in politics, in our work, and in every other sphere of our lives -- but while some of these assumptions are no doubt true, it is likely, that more are false and some are harmful. So the critical examination of our presuppositions -- which is a philosophical activity -- is morally as well as intellectually important.
mistake learning knowledge
It is often asserted that discussion is only possible between people who have a common language and accept common basic assumptions. I think that this is a mistake. All that is needed is a readiness to learn from one's partner in the discussion, which includes a genuine wish to understand what he intends to say. If this readiness is there, the discussion wrighteous stupidityill be the more fruitful the more the partner's backgrounds differ.
beautiful dream attitude
Aestheticism and radicalism must lead us to jettison reason, and to replace it by a desperate hope for political miracles. This irrational attitude which springs from intoxication with dreams of a beautiful world is what I call Romanticism. It may seek its heavenly city in the past or in the future; it may preach 'back to nature' or 'forward to a world of love and beauty'; but its appeal is always to our emotions rather than to reason. Even with the best intentions of making heaven on earth it only succeeds in making it a hell - that hell which man alone prepares for his fellow-men.
