"Let us yield a bit. Let us grant socialism a few more years. Socialism is so obsolete, it is dying by itself.… Did I say socialism? I assure you on my honor this was not a mental slip. This was a slip of the tongue. Do not forget that. Capitalism—and I say it with such gusto—capitalism is so obsolete that it is dying by itself."

“I feel my belief in sacrifice and struggle getting stronger. I despise the kind of existence that clings to the miserly trifles of comfort and self-interest. I think that a man should not live beyond the age when he begins to deteriorate, when the flame that lighted the brightest moment of his life has weakened.”

“Some people wanted to know what the policy of the Revolutionary Government of Cuba was. Very well, then, this is our policy.”

“Revolution is the sense of the historical moment; it is changing everything that must be changed; it is full equality and freedom; it is being treated and treating others like human beings; it is emancipating ourselves, by ourselves and with our very own efforts; it is challenging the dominant powerful forces within and outside of the social and national arena; it is defending the values one believes in at the cost of any sacrifice; it is modesty, selflessness, altruism, solidarity and heroism; it is fighting with audacity, intelligence and realism; it is never telling a lie or violating ethical principles; it is the profound conviction that there is no force on earth that can crush truth and ideas. Revolution is unity, it is independence, it is fighting for our dreams of justice for Cuba and the world that is the basis of our patriotism, our socialism and our internationalism.”

“Fellow workers and peasants, this is the socialist and democratic revolution of the working people, with the working people, and for the working people. And for this revolution of the working people, by the working people, and for the working people we are prepared to give our lives.”

“At Punta del Este a great ideological battle unfolded between the Cuban Revolution and Yankee imperialism. Who did they represent there, for whom did each speak? Cuba represented the people; the United States represented the monopolies. Cuba spoke for America's exploited masses; the United States for the exploiting, oligarchical, and imperialist interests; Cuba for sovereignty; the United States for intervention; Cuba for the nationalization of foreign enterprises; the United States for new investments of foreign capital. Cuba for culture; the United States for ignorance. Cuba for agrarian reform; the United States for great landed estates. Cuba for the industrialization of America; the United States for underdevelopment. Cuba for creative work; the United States for sabotage and counterrevolutionary terror practiced by its agentsthe destruction of sugarcane fields and factories, the bombing by their pirate planes of the labor of a peaceful people. Cuba for the murdered teachers; the United States for the assassins. Cuba for bread; the United States for hunger. Cuba for equality; the United States for privilege and discrimination. Cuba for the truth; the United States for lies. Cuba for liberation; the United States for oppression. Cuba for the bright future of humanity; the United States for the past without hope. Cuba for the heroes who fell at Giron to save the country from foreign domination; the United States for mercenaries and traitors who serve the foreigner against their country. Cuba for peace among peoples; the United States for aggression and war. Cuba for socialism; the United States for capitalism.”

“If we had paused to tell the people that we were Marxist-Leninists while we were on Pico Turquino and not yet strong, it is possible that we would never have been able to descend to the plains.”
