Today none of the old assertions are accepted any longer just because they were written long ago. Instead, people demand proof in practice of what is asserted; they want a scientific analysis of all assertions. Out of this dissatisfaction, revolutionary ideas are born and spread more and more throughout the world, backed by the living examples of how technology can be put at the service of man, as has happened in the socialist countries.

American capitalism replaced some of the old colonial capitalisms in the countries that began their independent life. But it knows that this is transitory and that there is no real security for its financial speculation in these new territories. The octopus cannot there apply its suckers firmly. The claw of the imperial eagle is trimmed. Colonialism is dead or is dying a natural death in all these places.

Whoever pretends that a technician, an architect, a doctor, an engineer, or any type of scientist should merely work with the in­struments in his own specific field while his people starve to death or fall in battle, has in fact taken the side of the enemy. He is not apolitical, he is political-but in opposition to movements for lib­eration.

Hay que ser duro pero jamas perder la ternura.[It is necessary to be hard but never to lose the tenderness]

if we center our efforts on war prepa­rations, we cannot build what we want, we cannot devote ourselves to creative work. All work, all capital invested in preparing for military action, is labor lost, money lost. Unfortunately, it has to be done, because others are preparing. But the money I am most saddened to see leave the National Bank coffers-and I say this with all honesty and pride as a soldier-is money to pay for some weapon of destruc­tion.

Without or­ganization, ideas, after some initial momentum, start losing their effect. They become routine, degenerate into conformity, and end up simply a memory. I raise this warning because too often, in this short but rich period of our revolution, many great initiatives have failed. They have been forgotten because of the lack of an organiza­tional apparatus needed to keep them going and bring them to frui­tion.

The first frictions and difficulties with the "northern giant" began immediately. These frictions were logi­cal if you consider that a country accustomed to special treatment suddenly saw that this little "colony" in the Caribbean irreverently sought to speak the only language a revolution can speak: the lan­guage of equal treatment.

To the powerful masters we repre­sent all that is absurd, negative, irreverent, and disruptive in this America that they so despise and scorn. But on the other hand, to the great mass of the American people (I'm referring to Our America, which is everything south of the Rio Bravo)-these peoples derisively called "mestizos"-we represent everything noble, sincere, and combative.

Our youth must always be free, discussing and exchanging ideas, concerned with what is happening throughout the entire world, open to using technology coming from any part of the world; wel­coming whatever the world might offer us. And you must always be sensitive to the struggle, the sufferings, and the hopes of oppressed peoples everywhere.This is how we will build our future.
