Ernesto Che Guevara

To send men to the firing squad, judicial proof is unnecessary. These procedures are an archaic bourgeois detail. This is a revolution! And a revolutionary must become a cold killing machine motivated by pure hate. We must create the pedagogy of the paredón [execution wall].

When asked whether or not we are Marxists, our position is the same as that of a physicist, when asked if he is a __ewtonian_ or of a biologist when asked if he is a __asteurian.__here are truths so evident, so much a part of the peoples_ knowledge, that it is now useless to debate them. One should be a __arxist_ with the same naturalness with which one is a __ewtonian_ in physics or a __asteurian._ 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 __insteinian_ relativity or of Planck__ quantum theory in relation to Newton__ 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__ body of cultural and scientific knowledge. We accept it with the naturalness of something that requires no further argument.

If you tremble with indignation at every injustice then you are a comrade of mine.
