“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 against the onslaught of the intolerant, then the tolerant will… — Karl R. Popper Copy Share Image
“Most of us, it seems, have a strong inclination to accept the peculiarities of our social environment as if they were ‘natural’.” — Karl R. Popper Copy Share Image
“The empirical basis of objective science has thus nothing ‘absolute’ about it.4 Science does not rest upon solid bedrock. The bold structure of its theories rises, as it were, above a swamp. It is like a building erected on piles. The piles are driven down from above into the swamp, but not down to any natural or ‘given’ base; and… — Karl R. Popper Copy Share
“Should you ever intend to dull the wits of a young man and to incapacitate his brains for any kind of thought whatever, then you cannot do better than give him Hegel to read. For these monstrous accumulations of words that annul and contradict one another drive the mind into tormenting itself with vain attempts to think anything whatever in… — Karl R. Popper Copy Share
“Historically, all ethics undoubtedly begin with religion; but I do not now deal with historical questions. I do not ask who was the first lawgiver. I only maintain that it is we, and we alone, who are responsible for adopting or rejecting some suggested moral laws; it is we who must distinguish between the true prophets and the false prophets.… — Karl R. Popper Copy Share
“Society and the individual are thus interdependent. The one owes its existence to the other. Society owes its existence to human nature, and especially… — Karl R. Popper Copy Share Image
“All political ideals, that of making the people happy is perhaps the most dangerous one. It leads invariably to the attempt to impose our scale of ‘higher’ values upon others, in order to make them realize what seems to us of greatest importance for their happiness; in order, as it were, to save their souls. It leads to Utopianism and… — Karl R. Popper Copy Share
“There is only one further use of violence in political quarrels which I should consider justified. I mean the resistance, once democracy has been attained, to any attack (whether from within or without the state) against the democratic constitution and the use of democratic methods. Any such attack, especially if it comes from the government in power, or if it… — Karl R. Popper Copy Share
“The fascist appeal to ‘human nature’ is to our passions, to our collectivist mystical needs, to ‘man the unknown’. Adopting Hegel’s words just quoted, this appeal may be called the cunning of the revolt against reason. But the height of this cunning is reached by Hegel in this boldest dialectical twist of his. While paying lip-service to rationalism, while talking… — Karl R. Popper Copy Share
“Instead of the greatest happiness for the greatest number, one should demand, more modestly, the least amount of avoidable suffering for all; and further,… — Karl R. Popper Copy Share Image
“According to this conception, the ultimate causes of all social changes and political revolutions are not increasing insight into justice; they are to be sought not in the philosophy but in the economics of the epoch concerned. The growing realization that existing social institutions are irrational and unjust is only a symptom …’ It is the theory of which a… — Karl R. Popper Copy Share
“(a) Nationalism, in the form of the historicist idea that the state is the incarnation of the Spirit (or now, of the Blood) of the state-creating nation (or race); one chosen nation (now, the chosen race) is destined for world domination. (b) The state as the natural enemy of all other states must assert its existence in war. (c) The… — Karl R. Popper Copy Share
“We all remember how many religious wars were fought for a religion of love and gentleness; how many bodies were burned alive with the genuinely kind intention of saving souls from the eternal fire of hell. Only if we give up our authoritarian attitude in the realm of opinion, only if we establish the attitude of give and take, of… — Karl R. Popper Copy Share
