... In fact, if you look around, it is amazing how much of our view of the mind follows outlines of Freud’s thinking. We now know that conscious mentation is the tip of the iceberg, very much as Freud argued. We are now clearly aware of the importance of instinctual strivings. We have localized them to the hypothalamus, and to the amygdala. We know that sexual strivings are present in childhood. We realize that when we convert unconscious to conscious mental processes, a sort of broadcasting function goes on. We are aware of superego functions at a biological level, moral values that are built into our brains.
The purposes of a man's heart are deep waters, but a man of understanding draws them out.
