“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 past was that of colonialism and imperialism; the future belongs to humankind, to the peoples and the revolution.  And facts are proving this true in our hemisphere and elsewhere.”

“The revolutionary is a synthesis of human sensibility, the natural feeling of rejecting injustice and oppression”.

“Peace is just the primary condition so that we can overturn, according to our beliefs, the colossal sources of energy and resources necessary for all of humanity, and not just for one part of it, to be able to live honourably, decently and decorously.”
“What could never be imagined by those who commit big crimes against peoples in the middle of their euphoria over their impunity and ephemeral power, is that the truth, sooner or later, makes its way through.  So has it been for those who crucified Christ for conveying a message of love and solidarity to the poor and oppressed of Rome, two thousand years ago, and even for those who kept Nelson Mandela behind bars during 27 years for fighting the hideous Apartheid regime in the middle of the 20th century.” 

“The most important thing will be your full commitment to the most noble and human trade: saving lives and preserving health. More than doctors you shall be conscientious guardians of the most precious human possession; you shall be apostles and builders of a more humane world.”

"Humanity should be aware of what we have been so far and what we cannot continue to be. Presently, our species has enough accumulated knowledge, ethical values and scientific resources to move towards a new historical era of true justice and humanism."

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

“Terror has always been an instrument of the worst enemies of Mankind bent on suppressing and crushing the peoples’ struggle for freedom. It can never be the instrument of a truly noble and just cause”.

“Intelligence is the greatest treasure. The cultivated intelligence, the human capital is what makes it possible that we can speak here of thousands of doctors helping other countries”

“Cuba has twice as many doctors per capita as all of the highest developed nations. No country has given, or is giving, more support to other peoples’ health care services, free of charge, than Cuba and no other has saved more lives. Thus, our people do not have, nor could it have, any inclination to become a bio-weapons producer.”

... Human beings are capable of conceiving the noblest of ideas, of holding the most generous feelings and, convinced that by overcoming the powerful instincts with which nature has imbued them, they can give their lives for what they feel and believe in. This has been proven often times throughout history.
