Check out "evolutionary psychology".
It has the potential to be a hard science someday, and even now it's a simple,
obvious-in-retrospect and ideology-free explanation of the mind. IMHO,
traditional psychology and psychoanalysis were way too complicated and
unfalsifiable to begin with, and are now simply obsoleted by EP.
