Integral (Theory)( Practice) recognizes deep structures of psycho-physical adaptation that underlie "surface activities". The deeper the underpinnings located in a way of life, the more similar that way of life seems to others existing in parallel. There's a convergence from "difference at the superficial level" to "similarity:identicality" at the deep levels.
The AQAL Matrix identifies four fundamental perspectives:
Upper Left: simpler subjective holons
Lower Left: more complex,higher integration intersubjective, resonant holons arising the the interaction of personal:subjective holons
Upper Right: simpler objective holons
Lower Right: systems of higher-integration holons made of simpler objective holons
As the graphic shows, there's another deep-structure-of-fourness: The TetraSeed (tetrahedral diagram).
The TetraSeed operates in every quadrant of the AQAL Matrix, in every line, at every level. It comprises a subjective fourness (central figure) and two objective fournesses ('sunburst' figure: one:process; the other:product).
It is the deep structure of all experience. the deep structure of all holons, whether subjective or objective, Left Quadrant or Right Quadrant, Upper Quadrant or Lower Quadrant.
