It’s hard to not see the tendency of the West to focus on intellect to be one of the ways for westerners to consider themselves “better” than the ones who don’t.
So what are other options to look at this problem?
If you looked at eastern cultures whose philosophy style is very different than the one of the West, you would notice that Jayne’s model is nothing special, and even quire simplistic. I think simplicity is very useful (big fan) but it can take you far into the bushes of wrong conclusions and it makes it hard for you to get back on track.
In Hindu culture there many words to describe different parts, mechanisms and functions of the mind that we simply don’t have words for. It gives them a framework to “think about thinking”, it gives them more tools for self-awareness. Are they more “conscious” in Jayne’s sense, if they have more words to describe and map their mind? Are we the westerners actually “zombies” compared to them, being stuck in words, labels, intellect, rationalisation, rather than living in the real world and seeing our thoughts for what they are rather than writing a fanfic about them, and being so proud of it?
My arguments would be similar though - we don’t know how much of that map is prescriptive or descriptive, how much of it is filling up details and writing a fanfic of itself, but millions if not billions people found it useful in building up self-awareness and tools for managing their own mind, emotions and thoughts, while all that Jayne’s concludes is imperialistic “we are better than them”.
