“ ”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
About Karl Popper
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".

I would rather find a single causal law than be the king of Persia!
The difference between Plato’s theory on the one hand, and that of the Old Oligarch and the Thirty on the other, is due to the influence of the Great Generation. Individualism, equalitarianism, faith in reason and love of freedom were new, powerful, and, from the point of view of the enemies of the open society, dangerous sentiments that had to be fought. Plato had himself felt their influence, and, within himself, he had fought them. His answer to the Great Generation was a truly great effort. It was an effort to close the door which had been opened, and to arrest society by casting upon it the spell of an alluring philosophy, unequalled in depth and richness. In the political field he added but little to the old oligarchic programme against which Pericles had once argued64. But he discovered, perhaps unconsciously, the great secret of the revolt against freedom, formulated in our own day by Pareto65; ‘To take advantage of sentiments, not wasting one’s energies in futile efforts to destroy them.’ Instead of showing his hostility to reason, he charmed all intellectuals with his brilliance, flattering and thrilling them by his demand that the learned should rule. Although arguing against justice he convinced all righteous men that he was its advocate. Not even to himself did he fully admit that he was combating the freedom of thought for which Socrates had died; and by making Socrates his champion he persuaded all others that he was fighting for it. Plato thus became, unconsciously, the pioneer of the many propagandists who, often in good faith, developed the technique of appealing to moral, humanitarian sentiments, for anti-humanitarian, immoral purposes. And he achieved the somewhat surprising effect of convincing even great humanitarians of the immorality and selfishness of their creed66. I do not doubt that he succeeded in persuading himself. He transfigured his hatred of individual initiative, and his wish to arrest all change, into a love of justice and tempera
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.
