The problem of peaceful transition to socialism, we do not discuss it as a theoretical question. But in America it is very difficult, and it is nearly impossible. That is why specifically in America we say that the road to the liberation of peoples, which will be the road of socialism will go through bullets in almost all countries.

I understand that the American people has a right and especially the press, which is not very friendly to us, to make all suppositions and ideas about this fact [suicide by Augusto Martinez] - this disgraced fact.

One has to grow hard but without ever losing tenderness.

It's a sad thing not to have friends, but it is even sadder not to have enemies.

To send men to the firing squad, judicial proof is unnecessary. These procedures are an archaic bourgeois detail. This is a revolution! And a revolutionary must become a cold killing machine motivated by pure hate.

To execute a man we don't need proof of his guilt. We only need proof that it's necessary to execute him. It's that simple.

The merit of Marx is that he suddenly produces a qualitative change in the history of social thought. He interprets history, understands its dynamic, predicts the future, but in addition to predicting it (which would satisfy his scientific obligation), he expresses a revolutionary concept: the world must not only be interpreted, it must be transformed. Man ceases to be the slave and tool of his environment and converts himself into the architect of his own destiny.
