Back in the 80s he wrote a book called "The Society of Mind" which I think is an amazing book. The core theory, which really resonated with me and stuck with me, is that we do not consist of a single mind. Our consciousness is a set of smaller subsegments (he calls them agents) that work (generally) together. If you think about the fact that looking at our brain you can see the evolutionary differences compared with other organism,s this starts to make a lot of sense. We have these different systems that have varying ages, with natural selection putting more pressure to develop a new system or enhance an old one, and the brain winding up almost like a tree trunk with different rings. It makes sense these smaller chunks do their own thing then "talk" to other parts. we even have language referencing it, "I'm of two minds about XYZ", and diseases like schizophrenia and hallucinations we trace to various parts of the brain not recognizing each other or not working properly together. We have studies that seem to indicate some decisions being made before we consciously think about them. About a decade ago I really started to feel like I've begun to recognize different "aspects" and understand why I feel the way I do by understanding this theory. An example is, if I have a big decision, and I find that I'm undecided and really unhappy while trying to come to a conclusion, it's usually because I've actually already decided, and I'm unhappy because I'm arguing with myself, I'm not accepting that decision. Rarely have I been unhappy with the decision I'd already made, too. He's a brilliant guy with some amazing work going back decades.
