In describing the human "self" or individual, or personal identity, who we are and what makes us tick... analytically...the source of our decisions, actions, "What comes out"... what we decide we are willing to actually utter...

I am aware of Freuds suggested Id, Ego, and Superego.  And Maslow's Heirarchy of Human Needs and his categorizations into physiological, social, etc.

If I had of "stayed in school", and gotten to Philosophy 501, instead of being a second year dropout... are there other contemporary/modern contributors analysis of "Who we are, how we think, and why we think?"

I don't even know if... are Maslow and Freud good "foundations", from a philosophical assessment of "systems of breaking down and describing an identity"?  Sometimes original theories get updated, made better... 

- Such as Darwin's evolution of species being supported and improved upon by our discovery of genetics and mutations and the chemical way characteristics and traits are handed down generation to generation.

- The "Big Bang" and expansion getting improved upon (mathematically, theoretically) by the invocation of onconfirmed "Dark Matter" and "Dark Energy" to create the fuller "LamdaCDM" model.

Are there more popular, more accepted, more betterer (grin) analysis of self, that one learns about within later years of Philosophy?  Please.

(This is my first question that I think might fit the model of this site, just right.  Fingers crossed.  I am interested to see what can be learned.)

Oh.  Maybe someone has grouped and categorized the input from "others" as one grows up and becomes who we become?  The exposures and opportunities to absorb and learn from observation and experience.  Some sort of analysis of that aspect of who we are, by way of "Path's found, paths taken, paths walked"?  Or some system of grouping I am not aware of??

We all recognize we are not the same person we would be, if we were say, born into a royal family, or the off-spring of a pair of Harvard Professors, or an A-list actor or owner of a multi-billion dollar business empire.  (Not that I would wish any of the above on myself or any other).  I just mean to say, it seems obvious... "birth and upbringinging" are a large part of "Who we have become".  Maybe there has been an analyst that has thought that stuff through and come up with a good syntheses?

Anything along these lines would be appreciated.
