“If religious feeling is put in opposition to social change, then it does become an opium, but if it is joined to the struggle for social change then it is a wonderful medicine.”

I think that a man should not live beyond the age when he begins to deteriorate, when the flame that lighted the brightest moment of his life has weakened.

I don’t think that the contradictions between capitalism and socialism can be resolved by war. This is no longer the age of the bow and arrow. It’s the nuclear age, and war can annihilate us all. The only way to achieve solutions seems to be for the different social systems to coexist.

There is talk of the failure of socialism, and where is the success of capitalism in Africa, Asia, and in Latin America?

Capitalism has neither the capacity, nor the morality, nor the ethics to solve the problems of poverty.

So these Red Sox, are they a Communist organization?

We are not only a Latin American nation, we are an Afro-American nation also.

The universities are available only to those who share my revolutionary beliefs.

Repetition is a revolutionary virtue.

I never saw a contradiction between the ideas that sustain me and the ideas of that symbol, of that extraordinary figure, Jesus Christ.

Quality of life lies in knowledge, in culture. Values are what constitute true quality of life, the supreme quality of life, even above food, shelter and clothing.

I believe that all of us ought to retire relatively young.

We are going to give a little something, a few little years more, to socialism, because socialism is defunct. It dies all by itself. The bad thing is that socialism, being a victim of its Did I say socialism?

I am not a dictator, and I do not think I will become one. I will not maintain power with a machine gun.

There are enough doctors on the planet so that nobody has to die for lack of attendance.

There is nothing that compares to the Holocaust.

I do not conceive of any manifestation of culture, of science, of art, as purposes in themselves. I think the purpose of science and culture is man.

Always laugh when you can; it is cheap medicine. Merriment is a philosophy not well understood. It is the sunny side of existence.

I will give no deadly medicine to any one if asked, nor suggest any such counsel; and in like manner I will not give to a woman a pessary to produce abortion.

When you flop, that’s just another message that you don’t know how to play me. Stand up and take your medicine like a man.

Psychiatry is a strange field because, unlike any other field of medicine, you never really finish.

I tell you, it’s funny because the only time I think about HIV is when I have to take my medicine twice a day.

The greatest medicine of all is teaching people how not to need it

There is no more effective medicine to apply to feverish public sentiments than figures.

Medicine is of all the Arts the most noble; but, owing to the ignorance of those who practice it, and of those who, inconsiderately, form a judgment of them, it is at present behind all the arts.
