“Man is the only animal for whom his own existence is a problem which he has to solve.”

“Alienation as we find it in modern society is almost total… Man has created a world of man-made things as it never existed before. He has constructed a complicated social machine to administer the technical machine he built. The more powerful and gigantic the forces are which he unleashes, the more powerless he feels himself as a human being. He is owned by his creations, and has lost ownership of himself.”

“Love is the only sane and satisfactory answer to the problem of human existence.”

“The real opposition is that between the ego-bound man, whose existence is structured by the principle of having, and the free man, who has overcome his egocentricity.”

“A person who has not been completely alienated, who has remained sensitive and able to feel, who has not lost the sense of dignity, who is not yet "for sale", who can still suffer over the suffering of others, who has not acquired fully the having mode of existence - briefly, a person who has remained a person and not become a thing - cannot help feeling lonely, powerless, isolated in present-day society. He cannot help doubting himself and his own convictions, if not his sanity. He cannot help suffering, even though he can experience moments of joy and clarity that are absent in the life of his "normal" contemporaries. Not rarely will he suffer from neurosis that results from the situation of a sane man living in an insane society, rather than that of the more conventional neurosis of a sick man trying to adapt himself to a sick society. In the process of going further in his analysis, i.e. of growing to greater independence and productivity,his neurotic symptoms will cure themselves.”

“What does one person give to another? He gives of himself, of the most precious he has, he gives of his life. This does not necessarily mean that he sacrifices his life for the other—but that he gives him of that which is alive in him; he gives him of his joy, of his interest, of his understanding, of his knowledge, of his humor, of his sadness—of all expressions and manifestations of that which is alive in him. In thus giving of his life, he enriches the other person, he enhances the other's sense of aliveness by enhancing his own sense of aliveness. He does not give in order to receive; giving is in itself exquisite joy. But in giving he cannot help bringing something to life in the other person, and this which is brought to life reflects back to him.”

“The mature response to the problem of existence is love.”
