“The deepest need of man, then, is the need to overcome his separateness, to leave the prison of his aloneness. The absolute failure to achieve this aim means insanity, because the panic of complete isolation can be overcome only by such a radical withdrawal from the world outside that the feeling of separation disappears—because the world outside, from which one is separated, has disappeared.”

German psychoanalyst and social philosopher of the mid-20th century, Erich Fromm was a leading figure in humanistic psychology. His work bridges psychology and sociology, exploring themes of love, freedom, and the human condition through concepts like "escape from freedom" and "the art of loving." He remains influential for his critiques of capitalism and his humanistic approach to mental health.
