“Religious education is demanded by the nation generally and by the instincts of human nature.”

University of Havana address (2005)
Context: Man is born egotistical, a result of the conditioning of nature. Nature fills us with instincts; it is education that fills us with virtues. Nature makes us do things instinctively; one of these is the instinct for survival which can lead to infamy, while on the other side, our conscience can lead us to great acts of heroism. It doesn’t matter what each one of us is like, how different we are from each other, but when we unite we become one.
It is amazing that in spite of the differences between human beings, they can become as one in a single instant or they can be millions, and they can be a million strong just through their ideas. Nobody followed the Revolution as a cult to anyone or because they felt personal sympathy with any one person. It is only by embracing certain values and ideas that an entire people can develop the same willingness to make sacrifices of any one of those who loyally and sincerely try to lead them toward their destiny.

1920s, The Aims of Education (1929)
Context: The essence of education is that it be religious. Pray, what is religious education? A religious education is an education which inculcates duty and reverence. Duty arises from our potential control over the course of events. Where attainable knowledge could have changed the issue, ignorance has the guilt of vice. And the foundation of reverence is this perception, that the present holds within itself the complete sum of existence, backwards and forwards, that whole amplitude of time, which is eternity.

My Race (1893)
Context: What right do white racist, who believe their race is superior, have for complaining about black racists, who see something special in their own race? What right do black racists, who see a special character in their race, have for complaining about white racists? White men who think their race makes them superior to black men admit the idea of racial difference and authorize and initiate black racists. Black men who proclaim their race — when what they are really proclaiming is the spiritual identity that distinguishes one ethnic group from another — authorize and incite white racists. Peace demands of Nature the recognition of human rights; discrimination is contrary to Nature and to the enemy of peace. Whites who isolate themselves also isolate Negroes. Negroes who isolate themselves incite and isolate whites.
