Marxism is a revolutionary worldview that must always struggle for new revelations. Marxism must abhor nothing so much as the possibility that it becomes congealed in its current form. It is at its best when butting heads in self-criticism, and in historical thunder and lightning, it retains its strength.

Marxism was a philosophical or semi-philosophical doctrine and a political ideology which was used by the as the main source of legitimacy and the obligatory faith.

Marxism is not only the theory of socialism, it is an integral world outlook, a philosophical system, from which Marx's proletarian socialism logically follows. This philosophical system is called dialectical materialism.

Marxism is a flight from the magic of the person and the mystique of hierarchy. It distorts the character of western culture, which is based on the charismatic power of person. Marxism can work only in pre-industrial societies of homogeneous populations. Raise the standard of living, and the rainbow riot of individualism will break out. Personality and art, which Marxism fears and censors, rebound from every effort to oppress them.

In my opinion, Marxism is a great creed of human liberation. It is the creed which says that when all other empires fade and vanish, our business is to enlarge the empire of the human mind

There is a close and obvious connection between the embrace of Marxist socialism and the social critical impulse. Marxism is a philosophy of intense moral indignation -- a worldview that helps to organize and systematize moral passion and which provides a seemingly scientific foundation for protesting social injustice. Marxism performs additional religious functions by pointing towards a better future which will arrive as a combined result of both the inexorable forces of history and the freely chosen effort of individuals who achieved the proper understanding of social forces. Leszek Kolakowski concluded his monumental study of Marxism as follows:

Marxism emerged not only with the intention of explaining scientifically everything in the world, but in addition to this, as a representative of the ‘hurt and injured’ classes of the world, expressing thus the centuries old dream of an earthly paradise. But dreams and wishes have nothing to do with science.

Marxism is the religion with a thousand faces.

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.

According to Marx, socialism, which is the first stage of Communism, covers a very long period. And, during this period, we will try to fulfill the principle “From each according to his ability, to each according to his work.” In other words, we will blend the interests of the individual with the interests of the country. There is no other way to mobilize interest in production among the masses, let’s admit it. And since the capitalist West will be helping us to overcome the backwardness we find ourselves in — the poverty that afflicts us — it doesn’t seem opportune to get caught up in the subtleties. However things go, the positive effects will be greater than the negative effects.

The Marxian theory of ideology predicts that the ruling ideas in any well functioning society will be ideas that promote the interests of the ruling class in that society, i.e., the class that is economically dominant. By the “ruling ideas” we should understand Marx to mean the central moral, political and economic ideas that dominate discussion in the mass media and in the corridors of power in that society. The theory is not peculiar to Marx, since the “classical realists” of antiquity like the Sophists and Thucydides advanced essentially the same theory: the powerful clothe their pursuit of self-interest in the garb of morality and justice. When Marx says that, “The ideas of the ruling class are in every epoch the ruling ideas” (The German Ideology) and that, “Law, morality, religion are to [the proletariat] so many bourgeois prejudices, behind which lurk in ambush just as many bourgeois interests” (The Communist Manifesto), he is simply translating in to Marxian terms the Sophistic view “that the more powerful will always take advantage of the weaker, and will give the name of law and justice to whatever they lay down in their own interests.” (W.K.C. Guthrie, The Sophists (1971), p. 60).

One ought to be "Marxist' with the same naturalness with which one is "Newtonian" in physics, or "Pasteurian" in biology, considering that if facts determine new concepts, these new concepts will never divest themselves of that portion of truth possessed by the older concepts they have outdated.

Every rebellion implies some kind of unity.

For the anarchist, rebellion is not only a statement of will but a statement of rightness and truth.
