In my latest model of development, I now include 8 bands - where a band represents the most general classification of stages - in total. And as each of these bands then contains three main levels, this leads to a model containing 24 major levels. Then in my holistic binary approach to development, the nature of all these levels is dynamically defined in both linear (1) and circular (0) terms, allowing for unique configurations with respect to differentiation and integration respectively. I also define sub-levels (usually 3 within each level). Then a key distinction is made as between the 3 main polarities of experience, external/internal whole/part and form/emptiness. And again in dynamic interactive terms, these polarities combine notions of relative independence (where the poles are separated) and relative interdependence (where the poles are viewed in a complementary manner) respectively. The first polarity set (external/internal) leads to the view of stages as relating inte...
