state, code, stage, depth
a good introductory article: https://medium.com/age-of-awareness/a-metamodern-guide-to-human-development-49fe8d8f0e8f
"state, code, stage, depth" is a framework for understanding human development, proposed by hanzi freinacht in the listening society book.
while it's heavily influenced by ken wilber's four quadrants⁹⁶ and the AQAL model⁹⁵, i believe this framework is way more accessible than them. no need to go into any kind of metaphysical territory. i find it the best/clearer introduction/definition of human development without needing to discuss woo.
