The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.

Forgive your enemies, but never forget their names.

Gentlemen, when the enemy is committed to a mistake we must not interrupt him too soon.

We must carry the war into every corner the enemy happens to carry it: to his home, to his centers of entertainment; a total war. It is necessary to prevent him from having a moment of peace, a quiet moment outside his barracks or even inside; we must attack him wherever he may be, make him feel like a cornered beast wherever he may move.

The great lesson of the guerrillas' invincibility is taking hold among the masses of the dispossessed. The galvanization of the national spirit; the preparation for more difficult tasks, for resistance to more violent repression. Hate as a factor in the struggle, intransigent hatred for the enemy that takes one beyond the natural limitations of a human being and converts one into an effective, violent, selective, cold killing machine. Our soldiers must be like that; a people without hate cannot triumph over a brutal enemy. Message to the Tricontinental (1967)

When I am without orders and unexpected occurrences arrive I shall always act as I think the honour and glory of my King and Country demand. But in case signals can neither be seen or perfectly understood, no captain can do very wrong if he places his ship alongside that of the enemy.
