Love is often nothing but a favorable exchange between two people who get the most of what they can expect, considering their value on the personality market.

I would consider a socialism a mixture of the minimum of centralization necessary for a modern industrial state, and a maximum of decentralization.

In our enthusiasm to dominate nature and to produce more material good - goods - we have transformed means into ends.

If it is true, as I have tried to show, that love is the only sane and satisfactory answer to the problem of human existence, then any society which excludes, relatively, the development of love, must in the long run perish of its own contradiction with the basic necessities of human nature.

Man's main task in life is to give birth to himself, to become what he potentially is. The most important product of his effort is his own personality.

Even if man's hunger and thirst and his sexual strivings are completely satisfied, 'he' is not satisfied. In contrast to the animal his most compelling problems are not solved then, they only begin. He strives for power or for love, or for destruction, he risks his life for religious, for political, for humanistic ideals, and these strivings are what constitutes and characterizes the peculiarity of human life.

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