It is unnecessary to say that Fidel Castro possesses the high qualities of a fighter and statesman: our path, our struggle, and our triumph we owed to his vision.

It is important to emphasize that guerrilla warfare is a war of the masses, a war of the people. The guerrilla band is an armed nucleus, the fighting vanguard of the people. It draws its great force from the mass of the people themselves.

I had a project for my life which involved 10 years of wandering, then some years of medical studies and, if any time was left, the great adventure of physics.

I am one of those people who believes that the solution to the world's problems is to be found behind the Iron Curtain.

A political event was that I met Fidel Castro, the Cuban revolutionary. He is a young, intelligent guy, very sure of himself and extraordinarily audacious; I think we hit it off well.

How easy it is to govern when one follows a system of consulting the will of the people and one holds as the only norm all the actions which contribute to the well being of the people.

The guerrilla fighters should be required to go to bed and get up at fixed hours. Games that have no social function and that hurt the morale of the troops and the consumption of alcoholic drinks should both be prohibited.

I could become very rich in Guatemala but by the low method of ratifying my title, opening a clinic, and specialising in allergies. To do that would be the most horrible betrayal of the two 'I's' struggling inside me: the socialist and the traveller.

I would probably have more in common with a whale than with a bourgeois married couple employed at worthy institutions that I would wipe from the face of the earth if it was given to me to do so.

The peasant must always be helped technically, economically, morally and culturally. The guerrilla 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.
