Austrian-British philosopher of science and social and política e falsificationism and for criticism of Plato, Hegel and Marx as totalitarian opponents of open society (1902-1994)
Sir Karl Raimund Popper (28 July 1902 – 17 September 1994) was an Austrian-British philosopher, academic and social commentator. One of the 20th century's most influential philosophers of science, Popper is known for his rejection of the classical inductivist views on the scientific method in favour of empirical falsification. According to Popper, a theory in the empirical sciences can never be proven, but it can be falsified, meaning that it can (and should) be scrutinised with decisive experiments. Popper was opposed to the classical justificationist account of knowledge, which he replaced with critical rationalism, namely "the first non-justificational philosophy of criticism in the history of philosophy".

There is no history of mankind, there is only an indefinite number of histories of all kinds of aspects of human life. And one of these is the history of political power. This is elevated into the history of the world. But this, I hold, is an offence against every decent conception of mankind. It is hardly better than to treat the history of embezzlement or of robbery or of poisoning as the history of mankind. For the history of power politics is nothing but the history of international crime and mass murder.
The belief in causality is metaphysical. It is nothing but a typical metaphysical hypostatization of a well-justified methodological rule- the scientist's decision never to abandon his search for laws. The metaphysical belief in causality seems thus more fertile in its various manifestations than any indeterminist physics metaphysics of the kind advocated by Heisenberg. Indeed, we can see that Heisenberg's comments have had a crippling effect on research. Connections which are not far to seek may easily be overlooked if its continually repeated that the search for any such connections is 'meaningless'.
I found that those of my friends who were admirers of Marx, Freud, and Adler, were impressed by a number of points common to these theories, and especially by their apparent explanatory power. These theories appeared to be able to explain practically everything that happened within the fields to which they referred. The study of any of them seemed to have the effect of an intellectual conversion or revelation, opening your eyes to a new truth hidden from those not yet initiated. Once your eyes were thus opened you saw confirming instances everywhere: the world was full of verifications of the theory. Whatever happened always confirmed it. Thus its truth appeared manifest; and unbelievers were clearly people who did not want to see the manifest truth; who refused to see it, either because it was against their class interest, or because of their repressions which were still 'un-analysed' and crying aloud for treatment.
The most characteristic element in this situation seemed to me the incessant stream of confirmations, of observations which 'verified' the theories in question; and this point was constantly emphasized by their adherents. A Marxist could not open a newspaper without finding on every page confirming evidence for his interpretation of history; not only in the news, but also in its presentation — which revealed the class bias of the paper — and especially of course in what the paper did not say. The Freudian analysts emphasized that their theories were constantly verified by their 'clinical observations'. As for Adler, I was much impressed by a personal experience. Once, in 1919, I reported to him a case which to me did not seem particularly Adlerian, but which he found no difficulty in analysing in terms of his theory of inferiority feelings, although he had not even seen the child. Slightly shocked, I asked him how he could be so sure. 'Because of my thousandfold experience,' he replied; whereupon I could not help saying: 'And with this new case, I suppo
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.
The idea of self-emancipation through knowledge, which was the basic idea of the Enlightenment, is in itself a powerful enemy of fanaticism; for it makes us try hard to detach ourselves or even to dissociate ourselves from our own ideas (in order to look at them critically) instead of identifying ourselves with them. And the recognition of the sometimes overwhelming historical power of ideas should teach us how important it is to free ourselves from the overpowering influence of false or wrong ideas. In the interests of the quest for truth and of our liberation from errors we have to train ourselves to view our own favourite ideas just as critically as those we oppose.
Again, we cannot search the whole world in order to make sure that nothing exists which the law forbids. Nevertheless, both kinds of strict statements, strictly existential and strictly universal, are in principle empirically decidable, each, however, in one way only: they are unilaterally decidable. Whenever it is found that something exists here or there, a strictly existential statement may thereby be verified, or a universal one falsified.
The tactical situation seems simple enough. Thanks to Marx’s prophecy, the Communists knew for certain that misery must soon increase. They also knew that the party could not win the confidence of the workers without fighting for them, and with them, for an improvement of their lot. These two fundamental assumptions clearly determined the principles of their general tactics. Make the workers demand their share, back them up in every particular episode in their unceasing fight for bread and shelter. Fight with them tenaciously for the fulfilment of their practical demands, whether economic or political. Thus you will win their confidence. At the same time, the workers will learn that it is impossible for them to better their lot by these petty fights, and that nothing short of a wholesale revolution can bring about an improvement. For all these petty fights are bound to be unsuccessful; we know from Marx that the capitalists simply cannot continue to compromise and that, ultimately, misery must increase. Accordingly, the only result — but a valuable one — of the workers’ daily fight against their oppressors is an increase in their class consciousness; it is that feeling of unity which can be won only in battle, together with a desperate knowledge that only revolution can help them in their misery. When this stage is reached, then the hour has struck for the final show-down. This is the theory and the Communists acted accordingly. At first they support the workers in their fight to improve their lot. But, contrary to all expectations and prophecies, the fight is successful. The demands are granted. Obviously, the reason is that they had been too modest. Therefore one must demand more. But the demands are granted again44. And as misery decreases, the workers become less embittered, more ready to bargain for wages than to plot for revolution. Now the Communists find that their policy must be reversed. Something must be done to bring the law of increasing misery into ope
