The Open Society and Its Enemies

by Karl Popper

In "The Open Society and Its Enemies," Karl Popper critiques the philosophical foundations of totalitarianism and defends the principles of a democratic, open society. Central to Popper's argument is the idea that history lacks inherent meaning and that the conflict between rationalism and irrationalism is crucial for contemporary thought. He introduces the paradox of tolerance, asserting that unlimited tolerance can lead to the demise of a tolerant society if it allows intolerant ideologies to flourish unchecked. Therefore, he contends that a tolerant society must retain the right to suppress intolerant movements, equating such suppression to a defense of its core values. Popper emphasizes the importance of rational discourse over irrational ideals and warns against Utopian thinking that seeks miraculous societal transformations without scientific grounding. He critiques figures like Hegel for promoting dangerous ideologies cloaked in complex language that can lead to moral irresponsibility and the justification of tyranny. Ultimately, Popper argues for a moral politics that prioritizes individual freedom and equal suffering over collective historical narratives, championing a future shaped by human action rather than deterministic historical forces. His call to action is a plea for individuals to embrace rationality, defend their freedoms, and engage ethically in the political sphere, recognizing the shared humanity that transcends national or historical boundaries.

Most of us, it seems, have a strong inclination to accept the peculiarities of our social environment as if they were ‘natural’.
I wish to make it clear that ‘history’ in the sense in which most people speak of it simply does not exist; and this is at least one reason why I say that it has no meaning.
This is why the conflict between rationalism and irrationalism has become the most important intellectual, and perhaps even moral, issue of our time.
The so-called paradox of freedom is the argument that freedom in the sense of absence of any constraining control must lead to very great restraint, since it makes the bully free to enslave the meek. The idea is, in a slightly different form, and with very different tendency, clearly expressed in Plato.Less well known is the paradox of tolerance: 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 be destroyed, and tolerance with them. — In this formulation, I do not imply, for instance, that we should always suppress the utterance of intolerant philosophies; as long as we can counter them by rational argument and keep them in check by public opinion, suppression would certainly be unwise. But we should claim the right to suppress them if necessary even by force; for it may easily turn out that they are not prepared to meet us on the level of rational argument, but begin by denouncing all argument; they may forbid their followers to listen to rational argument, because it is deceptive, and teach them to answer arguments by the use of their fists or pistols. We should therefore claim, in the name of tolerance, the right not to tolerate the intolerant. We should claim that any movement preaching intolerance places itself outside the law, and we should consider incitement to intolerance and persecution as criminal, in the same way as we should consider incitement to murder, or to kidnapping, or to the revival of the slave trade, as criminal.
We must plan for freedom, and not only for security, if for no other reason than only freedom can make security more secure.
What a monument of human smallness is this idea of the philosopher king. What a contrast between it and the simplicity of humaneness of Socrates, who warned the statesmen against the danger of being dazzled by his own power, excellence, and wisdom, and who tried to teach him what matters most — that we are all frail human beings.
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.

What we need and what we want is to moralize politics, not to politicize morals.

I hold that he who teaches that not reason but love should rule opens up the way for those who rule by hate.
The future depends on ourselves, and we do not depend on any historical necessity.
The way of science is paved with discarded theories which were once declared self-evident;
Instead of the greatest happiness for the greatest number, one should demand, more modestly, the least amount of avoidable suffering for all; and further, that unavoidable suffering—such as hunger in times of an unavoidable shortage of food—should be distributed as equally as possible.
Great men may make great mistakes;
What I criticize under the name Utopian engineering recommends the reconstruction of society as a whole, i.e. very sweeping changes whose practical consequences are hard to calculate, owing to our limited experiences. It claims to plan rationally for the whole of society, although we do not possess anything like the factual knowledge which would be necessary to make good such an ambitious claim.
As indicated by our example, methodological nominalism is nowadays fairly generally accepted in the natural sciences. The problems of the social sciences, on the other hand, are still for the most part treated by essentialist methods. This is, in my opinion, one of the main reasons for their backwardness.
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 connection with them, until finally it collapses from sheer exhaustion. Thus any ability to think is so thoroughly destroyed that the young man will ultimately mistake empty and hollow verbiage for real thought. A guardian fearing that his ward might become too intelligent for his schemes might prevent this misfortune by innocently suggesting the reading of Hegel.
a rational analysis of the consequences of a decision does not make the decision rational; the consequences do not determine our decision; it is always we who decide.
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 more loudly about ‘reason’ than any man before or after him, he ends up in irrationalism; in an apotheosis not only of passion, but of brutal force: ‘It is’, Hegel writes, ‘the absolute interest of Reason that this Moral Whole’ (i.e. the State) ‘should exist; and herein lies the justification and merit of heroes, the founders of States—however cruel they may have been … Such men may treat other great and even sacred interests inconsiderately … But so mighty a form must trample down many an innocent flower; it must crush to pieces many an object on its path.
It is not the consciousness of man that determines his existence—rather, it is his social existence that determines his consciousness.
What we call nowadays totalitarianism belongs to a tradition which is just as old or just as young as our civilization itself
That such a surprisingly powerful philosophical method was taken seriously can be only partially explained by the backwardness of German natural science in those days. For the truth is, I think, that it was not at first taken really seriously by serious men (such as Schopenhauer, or J. F. Fries), not at any rate by those scientists who, like Democritus2, ‘would rather find a single causal law than be the king of Persia’. Hegel’s fame was made by those who prefer a quick initiation into the deeper secrets of this world to the laborious technicalities of a science which, after all, may only disappoint them by its lack of power to unveil all mysteries. For they soon found out that nothing could be applied with such ease to any problem whatsoever, and at the same time with such impressive (though only apparent) difficulty, and with such quick and sure but imposing success, nothing could be used as cheaply and with so little scientific training and knowledge, and nothing would give such a spectacular scientific air, as did Hegelian dialectics, the mystery method that replaced ‘barren formal logic’. Hegel’s success was the beginning of the ‘age of dishonesty’ (as Schopenhauer3 described the period of German Idealism) and of the ‘age of irresponsibility’ (as K. Heiden characterizes the age of modern totalitarianism); first of intellectual, and later, as one of its consequences, of moral irresponsibility; of a new age controlled by the magic of high-sounding words, and by the power of jargon. In order to discourage the reader beforehand from taking Hegel’s bombastic and mystifying cant too seriously, I shall quote some of the amazing details which he discovered about sound, and especially about the relations between sound and heat. I have tried hard to translate this gibberish from Hegel’s Philosophy of Nature4 as faithfully as possible; he writes: ‘§302. Sound is the change in the specific condition of segregation of the material parts, and in the negation of this condition;—merely an abstract or an ideal ideality, as it were, of that specification. But this change, accordingly, is itself immediately the negation of the material specific subsistence; which is, therefore, real ideality of specific gravity and cohesion, i.e.—heat. The heating up of sounding bodies, just as of beaten or rubbed ones, is the appearance of heat, originating conceptually together with sound.’ There are some who still believe in Hegel’s sincerity, or who still doubt whether his secret might not be profundity, fullness of thought, rather than emptiness. I should like them to read carefully the last sentence—the only intelligible one—of this quotation, because in this sentence, Hegel gives himself away. For clearly it means nothing but: ‘The heating up of sounding bodies … is heat … together with sound.’ The question arises whether Hegel deceived himself, hypnotized by his own inspiring jargon, or whether he boldly set out to deceive and bewitch others. I am satisfied that the latter was the case, especially in view of what Hegel wrote in one of his letters. In this letter, dated a few years before the publication of his Philosophy of Nature, Hegel referred to another Philosophy of Nature, written by his former friend Schelling: ‘I have had too much to do … with mathematics … differential calculus, chemistry’, Hegel boasts in this letter (but this is just bluff), ‘to let myself be taken in by the humbug of the Philosophy of Nature, by this philosophizing without knowledge of fact … and by the treatment of mere fancies, even imbecile fancies, as ideas.’ This is a very fair characterization of Schelling’s method, that is to say, of that audacious way of bluffing which Hegel himself copied, or rather aggravated, as soon as he realized that, if it reached its proper audience, it meant success.
Never can an authority admit that the intellectually courageous - those who dare to defy his authority - may be the most valuable type.
It is under the influence of such romantic ideas that individualism is still identified with egoism, as it was by Plato, and altruism with collectivism (i.e. with the substitution of group egoism for the individualist egoism). But this bars the way even to a clear formulation of the main problem, the problem of how to obtain a sane appreciation of one’s own importance in relation to other individuals. Since it is felt, and rightly so, that we have to aim at something beyond our own selves, something to which we can devote ourselves, and for which we may make sacrifices, it is concluded that this must be the collective, with its ‘historical mission’. Thus we are told to make sacrifices, and, at the same time, assured that we shall make an excellent bargain by doing so. We shall make sacrifices, it is said, but we shall thereby obtain honour and fame. We shall become ‘leading actors’, heroes on the Stage of History; for a small risk we shall gain great rewards. This is the dubious morality of a period in which only a tiny minority counted, and in which nobody cared for the common people. It is the morality of those who, being political or intellectual aristocrats, have a chance of getting into the textbooks of history. It cannot possibly be the morality of those who favour justice and equalitarianism; for historical fame cannot be just, and it can be attained only by a very few. The countless number of men who are just as worthy, or worthier, will always be forgotten.
I wish to apologize to the Kantians for mentioning them in the same breath as the Hegelians.
In previous chapters I have mentioned moral positivism (especially that of Hegel), the theory that there is no moral standard but the one which exists; that what is, is reasonable and good; and therefore, that might is right. The practical aspect of this theory is this. A moral criticism of the existing state of affairs is impossible, since this state itself determines the moral standard of things. Now the historicist moral theory we are considering is nothing but another form of moral positivism. For it holds that coming might is right. The future is here substituted for the present—that is all. And the practical aspect of the theory is this. A moral criticism of the coming state of affairs is impossible, since this state determines the moral standard of things. The difference between ‘the present’ and ‘the future’ is here, of course, only a matter of degree. One can say that the future starts to-morrow, or in 500 years, or in 100. In their theoretical structure there is no difference between moral conservatism, moral modernism, and moral futurism. Nor is there much to choose between them in regard to moral sentiments. If the moral futurist criticizes the cowardice of the moral conservative who takes sides with the powers that be, then the moral conservative can return the charge; he can say that the moral futurist is a coward since he takes sides with the powers that will be, with the rulers of to-morrow. I feel sure that, had he considered these implications, Marx would have repudiated historicist moral theory. Numerous remarks and numerous actions prove that it was not a scientific judgement but a moral impulse, the wish to help the oppressed, the wish to free the shamelessly exploited and miserable workers, which led him to socialism. I do not doubt that it is this moral appeal that is the secret of the influence of his teaching. And the force of this appeal was tremendously strengthened by the fact that he did not preach morality in the abstract. He did not pretend to have any right to do so. Who, he seems to have asked himself, lives up to his own standard, provided it is not a very low one? It was this feeling which led him to rely, in ethical matters, on under-statements, and which led him to the attempt to find in prophetic social science an authority in matters of morals more reliable than he felt himself to be. Surely, in Marx’s practical ethics such categories as freedom and equality played the major rôle. He was, after all, one of those who took the ideals of 1789 seriously. And he had seen how shamelessly a concept like ‘freedom’ could be twisted. This is why he did not preach freedom in words—why he preached it in action. He wanted to improve society and improvement meant to him more freedom, more equality, more justice, more security, higher standards of living, and especially that shortening of the working day which at once gives the workers some freedom. It was his hatred of hypocrisy, his reluctance to speak about these ‘high ideals’, together with his amazing optimism, his trust that all this would be realized in the near future, which led him to veil his moral beliefs behind historicist formulations.
