This reminds me of my old t'ai chi training. Yin and yang must be clearly differentiated and balanced in mind, body and deed. Theoretically when yin for example is 100% and yang 0% then yin transforms into yang.* And yet practically in the body and between bodies this never happens, as they must always be clearly differentiated to maintain balance.
If I were to put 100% of my weight forward with no countervailing backward counterweight then I would lose balance and fall on my face. Even in yielding to an attack one must adhere to their opponent with at least 4 ounces of pressure** to be able to read his force, trajectory, etc. Complete yielding results in losing touch with the opponent and in being pushed over. Hence something just doesn't seem right to me with these theoretical notions that one becomes the other at the extreme poles. And why I tend to prefer the always already in relation between opposing forces which are never completely the same, completely different, and never completely transform or reduce into the other. We also see this at play with Harman above in his fourfold of 2 polarities, with ever-shifting dynamic balance being the integrating factor.
* We might say this only happens on extreme ends of an abstract hierarchy which posits such absolutes. Whereas for L&J hierarchies start in the middle with the concrete basic categories closest to lived experience and work their way out to the edges, hence providing concrete balance to otherwise metaphysical premises.
** Hence the yin/yang diagram always contains a small seed of opposition in the predominating black area and vice versa. This small seed indicates there is never 100% of one or the other lest they lose connection and fly off into metaphysical heights and depths, primordial substance or being.
"“I would like to suggest that we can frame this discussion within two conceptions of withdrawal: absolute and contingent (the first associated with the work of Tim Morton and Graham Harman, the second with Michael and Levi Bryant).”
Don't forget part 1 of the above, where Bryant "skillfully differentiate[s] his own understanding of withdrawal from Graham Harman’s by further articulating philosophical commitments consistent with a move towards integrating process-relational thinking with object-orientated investigations."
