" "The difficulties connected with my criterion of demarcation (D) are important, but must not be exaggerated. It is vague, since it is a methodological rule, and since the demarcation between science and nonscience is vague. But it is more than sharp enough to make a distinction between many physical theories on the one hand, and metaphysical theories, such as psychoanalysis, or Marxism (in its present form), on the other. This is, of course, one of my main theses; and nobody who has not understood it can be said to have understood my theory.
The situation with Marxism is, incidentally, very different from that with psychoanalysis. Marxism was once a scientific theory: it predicted that capitalism would lead to increasing misery and, through a more or less mild revolution, to socialism; it predicted that this would happen first in the technically highest developed countries; and it predicted that the technical evolution of the 'means of production' would lead to social, political, and ideological developments, rather than the other way round.
But the (so-called) socialist revolution came first in one of the technically backward countries. And instead of the means of production producing a new ideology, it was Lenin's and Stalin's ideology that Russia must push forward with its industrialization ('Socialism is dictatorship of the proletariat plus electrification') which promoted the new development of the means of production.
Thus one might say that Marxism was once a science, but one which was refuted by some of the facts which happened to clash with its predictions (I have here mentioned just a few of these facts).
However, Marxism is no longer a science; for it broke the methodological rule that we must accept falsification, and it immunized itself against the most blatant refutations of its predictions. Ever since then, it can be described only as nonscience — as a metaphysical dream, if you like, married to a cruel reality.
Psychoanalysis is a very different
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".

This false epistemology, however, has also led to disastrous consequences. The theory that truth is manifest — that it is there for everyone to see, if only he wants to see it — this theory is the basis of almost every kind of fanaticism. For only the most depraved wickedness can refuse to see the manifest truth; only those who have reason to fear truth conspire to suppress it.
We see here that Plato recognizes only one ultimate standard, the interest of the state. Everything that furthers it is good and virtuous and just; everything that threatens it is bad and wicked and unjust. Actions that serve it are moral; actions that endanger it, immoral. In other words, Plato’s moral code is strictly utilitarian; it is a code of collectivist or political utilitarianism. The criterion of morality is the interest of the state. Morality is nothing but political hygiene.
This is the collectivist, the tribal, the totalitarian theory of morality: ‘Good is what is in the interest of my group; or my tribe; or my state.’ It is easy to see what this morality implied for international relations: that the state itself can never be wrong in any of its actions, as long as it is strong; that the state has the right, not only to do violence to its citizens, should that lead to an increase of strength, but also to attack other states, provided it does so without weakening itself. (This inference, the explicit recognition of the amorality of the state, and consequently the defence of moral nihilism in international relations, was drawn by Hegel.)
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.
