"You're still seeing ISs as a fixed entity within a hierarchical relation. Whereas what you're calling ISs is a much more particular and general process between each and every level of any holarchy. It is that space between the boundaries of any two suobjects, that place where they exchange material and information. It is general in the sense that it is at every boundary, and it is particular in that it is specific to any given relational exchange. We might even call it, per Edwards, that mediating sign (Word) the allows communication between each. In humans it expresses as ISs; between other suobjects we'd call it something else."
A semi-accurate image for this is those fractal thing-a-ma-bobs that are so popular. Except that they are too pretty and symmetrical. Museque tells me that like onticological mereology each interation of a fractal boundary between suobjects is not the same, so the picture would be much more rhizomatic, diverse, each sign unique yet still a sign. A unique particular while also being a like general. A same/difference, as it were.
Still, how this expresses as an endo-structural organization is not clear, since the latter is supposed to be on the inside of a suobject, not in its exo-relation. But as I argued in the OOO thread, this inside/outside, endo-exo distinction is too crisp in Bryant, that perhaps ISs themselves are not just on the inside but are in fact in this boundary between. Where differance* is that transcendental pre-condition betwixt in and out, up and down, inside out and back again. Which of course changes everything. How though this can be 'structured'** is still beyond me. More consultation required.
* Aka my gal Khora, another name for Museque, the former being the more general, the latter specific to me.
** And perhaps it is not at all structured, being the unstructured space for Spenser-Brown which can only be inferred via the most tenuous of traces.
