“Valdivia's actions symbolize man's indefatigable thirst to take control of a place where he can exercise total authority. That phrase, attributed to Caesar, proclaiming he would rather be first-in-command in some humble Alpine village than second-in-command in Rome, is repeated less pompously, but no less effectively, in the epic campaign that is the conquest of Chile. If, in the moment the conquistador was facing death at the hands of tht invincible Araucanian Caupolican, he had not been overwhelmed with fury, like a hunted animal, I do not doubt that judging his life, Valdivia would have felt death was fully justified. He belonged to that special class of men the species produces every so often, in whom a craving for limitless power is so extreme that any suffering to achieve it seems natural, and he had become the omnipotent ruler of a warrior nation.”

“The first commandment for every good explorer is that an expedition has two points: the point of departure and the point of arrival. If your intention is to make the second theoretical point coincide with the actual point of arrival, don't think about the means -- because the journey is a virtual space that finishes when it finishes, and there are as many means as there are different ways of 'finishing.' That is to say, the means are endless.”

“I would rather die standing up to live life on my knees.”

“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.”

“At the risk of seeming ridiculous, let me say that the true revolutionary is guided by a great feeling of love. It is impossible to think of a genuine revolutionary lacking this quality. We must strive every day so that this love of living humanity will be transformed into actual deeds, into acts that serve as examples, as a moving force.”

“I finally felt myself lifted definitively away on the winds of adventure toward worlds I envisaged would be stranger than they were, into situations I imagined would be much more normal than they turned out to be.”

“After graduation, due to special circumstances and perhaps also to my character, I began to travel throughout America, and I became acquainted with all of it. Except for Haiti and Santo Domingo, I have visited, to some extent, all the other Latin American countries. Because of the circumstances in which I traveled, first as a student and later as a doctor, I came into close contact with poverty, hunger and disease; with the inability to treat a child because of lack of money; with the stupefaction provoked by the continual hunger and punishment, to the point that a father can accept the loss of a son as an unimportant accident, as occurs often in the downtrodden classes of our American homeland. And I began to realize at that time that there were things that were almost as important to me as becoming famous for making a significant contribution to medical science: I wanted to help those people.”
