There was a revisit of the Jungian temperament types, and derivatives thereof, but this time with an emphasized intention of understanding others... and just maybe develop some kind of unifying theory. I know people don't fall neatly into these bins, but instead behave more like weighted sliders along various scales. I may have one "dominant" type but also have significant characteristics of another type.
However, it is helpful to learn more about the personality archetypes as corner data points, so to speak. Makes interpolation somewhat easier, but not really. It's like predicting chemical reactions with complicated materials...
... because these intrinsic types could be affected by environmental factors in all sorts of ways.
The references to Greek mythology are interesting, i.e. Dionysus (Artemis), Apollo (Persephone), Prometheus (Athena) & Epimetheus (Hestia). Perhaps I shall initiate a comprehensive (or selectively highlighted) study of mythologies from different cultures at some point...
As I was reading the book, I tried to pay attention to the various dynamics as different types interact. The description better illuminated certain aspects of my life, as I took the extrospective approach rather than my usual introspection. And perhaps it will help me to relate to other people better. My SO said that I've been improving, so there is hope haha.
