I think the best thing you can do, if you can stomach it, is watch a couple of his "Maps of meaning" lectures and notice the kinds of things he likes to repeat and focus on. It is very fascinating to me that his very odd ideas that were not popular in mainstream or in academics eventually became widely known after his rise to fame from the whole "refusing to use pronouns" thing. I'm sure someone could follow his path from a rather respected clinical psychologist to what is really more of an anthropologist through his career, while at the same time moving from being a more typical academic in psychology, to being completely niche in what he later worked on.
