Rowan here begins to draw on Ken Wilber with whom I am only very vaguely familiar. I haven't finished reading this part yet, but it feels like it's kind of similar to David Chapman and Meta-Rationality and Robert Kegan's 📙 The Evolving Self and so on. First you are a little baby, then you develop a confused adolescent multiplicity, then you gather yourself as an adult and make yourself kind of coherent, you even develop a playful agility of moving between selves, but beyond all this there's a next level of development, which is the Transpersonal.
