The spirit of a production-centered, commodity-greedy society is such that only the non-conformist can defend himself sufficiently against it. Those who are seriously concerned with love as the only rational answer to the problem of human existence must, then, arrive at the conclusion that important and radical changes in our social structure are necessary, if love is to become a social and not a highly individualistic, marginal phenomenon.

In the development of both capitalism and communism, as we visualize them in the next fifty or a hundred years, the processes that encourage human alienation will continue.

Critical and radical thought will only bear fruit when it is blended with the most precious quality man is endowed with - the love of life

The danger of the past was that men became slaves. The danger of the future is that men may become robots. True enough, robots do not rebel. But given man's nature, robots cannot live and remain sane, they become ''Golems',' they will destroy their world and themselves because they cannot stand any longer the boredom of a meaningless life.

Man's main task in life is to give birth to himself.

I want to mention that Marx shares something, if you don't mind the comparison, with the Old Testament: many people talk about him, but nobody has read him.

Only the person who has faith in himself is able to be faithful to others.
