"To speak of physical exercise and sports is to speak of health; it is to speak of discipline, of forming young people’s character, of healthy habits, of the battle against drugs. Sports are the antithesis of drugs; sports are the antithesis of alcoholism. Sports and physical exercise are a preventive remedy for many illnesses that can kill or disable, such as obesity, or a decrease in a person’s faculties".
"(...) 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".
"Nowadays men of science occupy a place of honor at research centers, laboratories and in factories producing medicines destined for human health, to overcome distances, concentrate energies, perfect investigation equipment so that it can function on earth and in space".
“The peoples of the Americas freed themselves from Spanish colonialism at the beginning of the last century, but they did not free themselves from exploitation. The feudal landowners assumed the authority of the Spanish rulers, the Indians continued in painful servitude, the Latin American man in one form or another remained a slave and the minimal hopes of the peoples succumbed under the power of the oligarchies and the strap of foreign capital”.
“Politics, I would say, is a combination of both science and art, although it is more art than science. We cannot forget that in both cases, responsibility lies with human beings, and they are as varied and variable as the particles contained in their genetic makeup”.
“"Their society" of privileged minorities over exploited majorities, "their class order" which they maintain with blood and fire over the dispossessed, "the homeland" which they alone enjoy, depriving the rest of the people of that enjoyment, to repress the revolutionaries who aspire to a new society, a just order, a true homeland for all”.
"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".
“Revolutions are not made at the whim of men; nobody could say that the whim of a group of men could lead people towards a revolution. Revolutions are made by necessities and people are not guilty for why revolutions happen; the people make revolutions forced by necessities, even though those of us involved in making them do so with great pleasure”.
"Today drugs are one of the most serious problems in this hemisphere and in Europe. In the war against drug trafficking and organized crime, encouraged in the enormous U.S. market, the Latin American countries are now losing almost ten thousand men each year, more than twice the number lost by the United States in the Iraq war. The number grows and the problem is very far from being resolved".
