Here is a conclusion I've come to after many years: among all the errors we may have committed, the greatest of them all was that we believed that someone really knew something about socialism, or that someone actually knew how to build socialism. It seemed to be a sure fact, as well-known as the electrical system conceived by those who thought they were experts in electrical systems. Whenever they said: “That’s the formula”, we thought they knew. Just as if someone is a physician. You are not going to debate anemia, or intestinal problems, or any other condition with a physician; nobody argues with the physician. You can think that he is a good doctor or a bad one, you can follow his advice or not, but you won't argue with him. Which of us would argue with a doctor, or a mathematician, or a historian, or an expert in literature or in any other subject? But we must be idiots if we think, for example, that economy is an exact and eternal science and that it existed since the days of Adam and Eve, and I offer my apologies to the thousands of economists in our country.

They contend, in their frenzy, that Cuba exports revolutions. There is room for the idea in their commercial, sleepless and pawnbroker minds, that revolutions can be bought or sold, rented, loaned, exported or imported as one more commodity. Ignorant of the objective laws which rule the development of human society, they believe that their monopolist, capitalist and semi-feudal regimes are eternal. Educated in their own reactionary ideology - a mixture of superstition, ignorance, subjectivism, pragmatism and other aberrations of the mind - they hold an image of the world and of the march of history which accords with their exploiting class interests. They presume that revolutions are born or die in the brains of individuals or by virtue of divine laws, and that the gods are on their side.

It is necessary that each Marxist-Leninist understand that he can contribute to Marxism-Leninism with an atom of his experience, that every solution he finds, every experience he acquires, in the act of solving a problem, will be one more experience with which he enriches Marxism-Leninism, because Marxism-Leninism has been enriched so much precisely by the experience of millions and millions of Marxist-Leninists acting in the reality of life.
