"All languages should survive! Out of 6000 or 7000 languages in the world, some 2000 have been lost in recent years and it has been estimated that in the next 20 years, another 2000 will be lost. When a dialect is lost it is human spiritual wealth that loses and history, our history as human beings, the history of how we evolved from animals into humans. Sometimes, however, I think that there are many animals that have never known slavery, capitalism nor the exploitation of animals by animals, which often behave better than humans do".
"Juan Miguel, your homeland appreciates your determination and courage in defense of its honor and its deserved victory! You have showed that at crucial times in the life of a people one man’s actions can compensate for the dishonor brought about by traitors like those who tried to steal your son".
"The duty of this new generation of revolutionary men and women is becoming an example of modest leaders, studious and tireless fighters for socialism. In the barbaric era of consumer societies, to overcome the capitalist production system that fosters and promotes selfish interests among human beings is, no doubt, a difficult challenge".
"(...) the first human right is the right to think, the right to believe, the right to live, the right to know, the right to know dignity, the right to be treated like other human beings, the right to be independent, right to sovereignty as a people, right to dignity as a man".
"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”.
