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.

I am more and more convinced that true revolutionaries must perceive the revolution, because of its creative and liberating nature, as an act of love. For me, the revolution, which is not possible without a theory of revolution - and therefore science - is not irreconcilable with love.

In the so called mistakes of Stalin lies the difference between a revolutionary attitude and a revisionist attitude. You have to look at Stalin in the historical context in which he moves, you don’t have to look at him as some kind of brute, but in that particular historical context. I have come to communism because of daddy Stalin and nobody must come and tell me that I mustn’t read Stalin. I read him when it was very bad to read him. That was another time. And because I’m not very bright, and a hard-headed person, I keep on reading him. Especially in this new period, now that it is worse to read him. Then, as well as now, I still find a Seri of things that are very good.

The guerilla fighter will be a sort of guiding angel who has fallen into the zone, helping the poor always and bothering the rich as little as possible in the first phases of the war. But this war will continue on its course; contradictions will continuously become sharper; the moment will arrive when many of those who regarded the revolution with a certain sympathy at the outset will place themselves in a position diametrically opposed; and they will take the first step into battle against the popular forces. At that moment the guerilla fighter should act to make himself into the standard bearer of the cause of the people, punishing every betrayal with justice.

Người viết những dòng nhật ký này đã không còn là con người của ngày xưa nữa khi đặt chân trở lại mảnh đất Argentina. Cuộc hành trình xuyên châu Mỹ - châu Mỹ (America) với chữ A viết hoa – đã làm thay đổi con người trong tôi nhiều hơn tôi tưởng. Tôi biết tôi không thể sống một cuộc sống bó hẹp, chật chội trong những khuôn khổ được nữa. Điều đó dường như đã tiềm ẩn từ lâu trong tôi dù chưa rõ ràng, và chuyến hành trình này đã khơi dậy tất cả.

Tạm biệt em, tình yêu duy nhất của anh,
Đừng run sợ trước bầy sói đói mồi
Cũng như giữa những thảo nguyên cô quạnh;
Anh luôn mang em theo trong tim mình
Và chúng ta sẽ đi cùng nhau cho đến khi con đường biến mất...
