All criticism is opposition. All opposition is counter-revolutionary.

No thieves, no traitors, no interventionists! This time the revolution is for real!

I do not conceive of any manifestation of culture, of science, of art, as purposes in themselves. I think the purpose of science and culture is man.

The solutions put forth by imperialism are the quintessence of simplicity...When they speak of the problems of population and birth, they are in no way moved by concepts related to the interests of the family or of society...Just when science and technology are making incredible advances in all fields, they resort to technology to suppress revolutions and ask the help of science to prevent population growth. In short, the peoples are not to make revolutions, and women are not to give birth. This sums up the philosophy of imperialism.

The first thing dictators do is finish free press, to establish censorship. There is no doubt that a free press is the first enemy of dictatorship.

I was a man who was lucky enough to have discovered a political theory, a man who was caught up in the whirlpool of Cuba's political crisis...; discovering Marxism...was like finding a map in the forest.

I began revolution with 82 men. If I had to do it again, I do it with 10 or 15 and absolute faith. It does not matter how small you are if you have faith and plan of action.
