“ Since January 1, 1959, Cuba has been, is, and will continue to be free forever. Its capacity for struggle and resistance, its profound political culture, and the awareness and courage of its people demonstrate that the Cuban Revolution, with its devotion to justice and its noble objectives, has created such a spirit of solidarity and heroism and has become so deeply rooted in the heart of the homeland that it has been rendered invincible.”

“In Cuba we have never cultivated hatred against the American people or blamed them for the aggressions perpetrated by the governments of that country. That would have run contrary to our political doctrines and our internationalist conscience, both well-proven throughout many years, and increasingly rooted in our ideas.”

“We, in our country, have a concept: all our young people must be prepared to lead the country, all our young people must be prepared to defend the homeland.  All of our young people, as their primary duty, must learn to read and write, all of them must acquire a revolutionary conscience.”
“Man’s consciousness does not determine the objective conditions. It is the other way around. Only after grasping this can we speak of revolution.  Beautiful words, needed to convey ideas, do not suffice; profound reflection is needed.”

"Humanity can be saved, for the empire is enduring a profound crisis. Without crises, no change is possible, without crises, no awareness can be built. A day of crisis can raise the awareness of people to a greater extent than 10 uneventful years, than 10 years without a crisis."

“[…]Let us fight against egoism, vanity and the sterile ambition for glory which are serpents devouring human souls; let us be the bearers of ideas and conscience, ever onward and upward, together with our glorious forefathers.”

“None of the problems affecting today’s world can be solved with the use of force, there is no global, technological or military power that can guarantee total immunity against such acts, because they can be organized by small groups, difficult to detect, and what is more complicated, carried out by suicidal people. Therefore, the general effort of the international community must be to put an end to a number of conflicts affecting the world, at least in this area. It is indispensable to put an end to world terrorism.”

… the human species has attained a maximum of consciousness while it is incapable of hurting for the suffering of others.

“We will make use of computers, not to create weapons of mass destruction and exterminate people but to convey knowledge to other peoples. From the economic point of view, the development of the intelligence and conscience of our fellow citizens, made possible by the Revolution, allow us not only to aid those in most need at no cost to us, but also to export specialized services, including healthcare services, to countries that have more resources than our own. In this field, the United States will never be able to compete with Cuba.”
