" 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 case. It is an interesting psychological metaphysics (and no doubt there is some truth in it, as there is so often in metaphysical ideas), but it never was a science. There may be lots of people who are Freudian or Adlerian cases: Freud himself was clearly a Freudian case, and Adler an Adlerian case. But what prevents their theories from being scientific in the sense here described is, very simply, that they do not exclude any physically possible human behaviour. Whatever anybody may do is, in principle, explicable in Freudian or Adlerian terms. (Adler's break with Freud was more Adlerian than Freudian, but Freud never looked on it as a refutation of his theory.)The point is very clear. Neither Freud nor Adler excludes any particular person's acting in any particular way, whatever the outward circumstances. Whether a man sacrificed his life to rescue a drowning, child (a case of sublimation) or whether he murdered the child by drowning him (a case of repression) could not possibly be predicted or excluded by Freud's theory; the theory was compatible with everything that could happen—even without any special immunization treatment.Thus while Marxism became non-scientific by its adoption of an immunizing strategy, psychoanalysis was immune to start with, and remained so. In contrast, most physical theories are pretty free of immunizing tactics and highly falsifiable to start with. As a rule, they exclude an infinity of conceivable possibilities. "

" How many winds of doctrine we have known in recent decades, how many ideological currents, how many ways of thinking. The small boat of thought of many Christians has often been tossed about by these waves - thrown from one extreme to the other: from Marxism to liberalism, even to libertinism; from collectivism to radical individualism; from atheism to a vague religious mysticism; from agnosticism to syncretism, and so forth. Every day new sects are created and what Saint Paul says about human trickery comes true, with cunning which tries to draw those into error (cf Ephesians 4, 14). Having a clear Faith, based on the Creed of the Church, is often labeled today as a fundamentalism. Whereas, relativism, which is letting oneself be tossed and 'swept along by every wind of teaching', looks like the only attitude acceptable to today's standards. We are moving towards a dictatorship of relativism which does not recognize anything as certain and which has as its highest goal one's own ego and one's own desires. However, we have a different goal: the Son of God, true man. He is the measure of true humanism. Being an 'Adult' means having a faith which does not follow the waves of today's fashions or the latest novelties. A faith which is deeply rooted in friendship with Christ is adult and mature. It is this friendship which opens us up to all that is good and gives us the knowledge to judge true from false, and deceit from truth. "

" When asked whether or not we are Marxists, our position is the same as that of a physicist, when asked if he is a “Newtonian” or of a biologist when asked if he is a “Pasteurian.”There are truths so evident, so much a part of the peoples’ knowledge, that it is now useless to debate them. One should be a “Marxist” with the same naturalness with which one is a “Newtonian” in physics or a “Pasteurian.” If new facts bring about new concepts, the latter will never take away that portion of truth possessed by those that have come before.Such is the case, for example, of “Einsteinian” relativity or of Planck’s quantum theory in relation to Newton’s discoveries. They take absolutely nothing away from the greatness of the learned Englishman. Thanks to Newton, physics was able to advance until it achieved new concepts of space. The learned Englishman was the necessary stepping-stone for that.Obviously, one can point to certain mistakes of Marx, as a thinker and as an investigator of the social doctrines and of the capitalist system in which he lived. We Latin Americans, for example, cannot agree with his interpretation of Bolivar, or with his and Engels’ analysis of the Mexicans, which accepted as fact certain theories of race or nationality that are unacceptable today.But the great men who discover brilliant truths live on despite their small faults and these faults serve only to show us they were human. That is to say, they were human beings who could make mistakes, even given the high level of consciousness achieved by these giants of human thought.This is why we recognize the essential truths of Marxism as part of humanity’s body of cultural and scientific knowledge. We accept it with the naturalness of something that requires no further argument. "

" Sometimes I wonder what the world would be like if we all got along. If there were no terrorism, Islamophobia, Western hypocrisy, corrupt government in African countries (especially Liberia), sexism, nativism, people like Donald Trump, stereotypes, war, Capitalism, Communism, Marxism and xenophobia.
