“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.”

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

"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."

“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”.

“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 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.”
“I must admit that Marx was right when he sketched out the idea that only when a truly rational, just and equitable social regime exists on this earth, will humankind have left prehistory behind.”
