" Though retaining what I considered the fundamentals of Freud's teachings, I realized by that time that my search for a better understanding had led me in directions that were at variance with Freud. If so many factors that Freud regarded as instinctual were culturally determined, if so much that Freud considered libidinal was a neurotic need for affection, provoked by anxiety and aimed at feeling safe with others, then the libido theory was no longer tenable. Childhood experiences remained important, but the influence they exerted on our lives appeared in a new light. Other theoretical differences inevitably followed. Hence it became necessary to formulate in my own mind where I stood in reference to Freud. "
