“To create bureaucracy is to blow human resources sky high, is to turn a man or a woman into a useless and parasite citizen; is to ditch human energy and intelligence, which should be destined for useful things for the society, useful things for the human beings.”

“Humanity needs these kinds of answers. Humanity is growing, humanity is multiplying. What isn’t growing, however, is the earth’s surface. Humanity shall have to do  everything in its power to increase its productivity per unit of surface, make as much of the earth or its surface productive, avail itself of all natural resources, all of science’s resources, for only those who are not revolutionaries, those who haven’t the slightest notion of the potential of humanity’s intelligence and willpower, can conceive of a world in which humanity starves”.

"The point is that it is not only the warrior what we admire in Che or the man capable of great feats. And what he did, and what he was doing, that fact in itself of facing with only a handful of men an entire oligarchic army, instructed by the Yankee advisers supplied by Yankee imperialism, supported by the oligarchies of all neighboring countries, that fact in itself constitutes an extraordinary feat".

“[…] whenever a man must face a challenge it is a test to him: a test of his character, a test of his will, a test of his courage as a revolutionary and as a man. And the concept of man implies the willingness to face tests and challenges.”
“No one but he was able to interpret the depth and essence and all the value of the Marxist theory. No one but he was able to interpret that theory and see it through to the bitter end. No one but he was able to develop it and enrich it the way he did.”

“Those, myself included, who defend socialism as the future of mankind, we should be in this battle which is not yet the battle of socialism, but the battle for a different world, free from poverty and oppression, the battle of hundreds of millions of people for whom it is pressing to convince the neocolonialists of the urgent need to change, or to defeat their policies through this struggle of the peoples”.

"Can the empire and the system responsible for all this really talk to the world about human rights? Human rights within a system where a large part of the population is unemployed, where women are prostituted, where children are abandoned? The numbers of abandoned children in Latin America are impressive, they number millions, many millions. How can this system offer hope to mankind? How can this system speak of consideration for mankind?
That’s why we have so much faith in socialism, and we have so much confidence in socialism and such deep socialist convictions".

"(...) that everything that today contributes to underdevelopment and poverty is tantamount to a flagrant attack on the ecology. As a result, tens of millions of men, women and children perish every year in the Third World, far more than in each of the two world wars. The unequal terms of trade, protectionism and the foreign debt are also an assault on the ecology and facilitate the destruction of the environment".

"An important biological species is endangered due to the accelerated and progressive destruction of its natural living conditions: man".

"Let the ecologic debt be paid and not the foreign debt. Let hunger disappear and not man."

“We look at the entire planet, in hopes it will survive, that the men will find enough intelligence and energy to survive, that mankind will find
enough consciousness and spirit to fight, because only fighting anarchy, fighting the madness of the empire and the system it represents mankind will be able to survive.”

"What Cuba has done for the human being, it has done with extraordinarily humane methods. In this blockaded country, there has never been a case of a banished person throughout its history; in this blockaded country, there are no death squads, which even kill children who live in the streets; in this blockaded country, no one can mention a single case of political assassination. And something else, as I tell many people: in this country, which struggles against that empire, there is not a single case of torture, not a single case (...)"
