Kirk, Spock and McCoy were Ego, Super-Ego and Id respectively.

Nice, very nice. Never thought of the relationship in that way. I will have to re-read Price of the Phoenix and Fate of the Phoenix with that idea in mind.

I haven’t read any of he appurtenant novels in the Star Trek universe.

This observation was just based on the interactions I saw repeated throughout the original series.

Subsequent Captains had at times one character or another that would fill one of these roles for a time but only in that original did the constant interplay between Kirk, Spock and McCoy meld the personalities into a firm interdependence that closely resembled the Freudian model.
