" Growth, then, demands detachment; and both growth and detachment are difficult to man. Psychologists who think like Fromm will say that it is precisely the refusal to accept the fact of growth that causes complexes, psychological retardations, and neuroses. For human nature shrinks from growth just as the child is reluctant to leave its mother's womb and it's mother's breast, and as the adolescent shrinks from the unknown adult world that rises before him. For psychological growth is a journey into unknown territory, and no one likes to leave the drab Platonic cave where he sits in sad security. Hence, man must muster all his psychological force to overcome each crisis and to avoid slipping back into infantilism."
