Erich Fromm (1900-1980)

In love the paradox occurs that two beings become one and yet remain two."
Immature love says: 'I love you because I need you.' Mature love says 'I need you because I love you.'"
That man can destroy life is just as miraculous a feat as that he can create it, for life is the miracle, the inexplicable. In the act of destruction, man sets himself above life; he transcends himself as a creature. Thus, the ultimate choice for a man, inasmuch as he is driven to transcend himself, is to create or to destroy, to love or to hate." The Sane Society
