What was Wang Bi's central philosophical concept?
My central concept revolves around the notion of 'wu' (non-being) as the primordial, undifferentiated origin from which all 'you' (being) emerges. I posited that the Dao, or the ultimate principle, is precisely this state of formless, pure potentiality. All things, in their multiplicity and change, are but manifestations or 'branches' stemming from this unified 'root.' Understanding this relationship between root and branch is key to grasping the Way.
