Some scattered thoughts on this:
1. All three of Holmes' categories get scrambled when you add more detail. A few quick scramblings: Plato did have essences, but a lot of relational aspects too (participation, emanation for the neos). Something somewhere else relates to something here, and the essence is transmitted.Leibniz and Spinoza were extraordinarly relational, while being of the 'mechanical' age. Kant in many ways is platonism turned inside out where, instead of a higher place beaming down the forms, we beam them out from ourselves. And so, like Plato, both essence-focused and relational. & sort of mechanical as well.
2. But you can also see the dialectic crystal of Holmes' break-down, regardless of how well it maps the terrain. There's the thing as it is (essence). Then there's the thing as a momentary 'snapshot' that expresses not itself, but what a linear process of matter-undergoing-laws-of-transformation looks like at time x. (mechanical). Finally, there's the addition of a 'ground' (transcendental apperception and spacetime, I guess, here) which provides a depth and connectedness for phenomena which Holmes' 'mechanical' would be lacking.
So (1) the thing as it is, which is the thing it is (2) it's fragmentation into blind matter and (3) its reintegration into a whole.
This sounds like the hero's quest. Many metaphilosophical accounts seem to tend that way
3. But there's definitely
some discernible progression. Is it that there's an innate tendency, in any time, to take the dialectic crystal Holme's has used, and cast it over any sort of material. So that two things are competing - an innate tendency to 'work out' that kind of framing with whatever material is handy (philosophical or not) + an attempt to adequately sketch what's happened in philosophy?
4.
I've speculated along these lines in an old post, though emphasizing (epochal?) experiences - shocks - which I think have made philosophizing possible, so to speak, instead of "conceptual equipment ... frameworks" throughout history: — 180 Proof
If the Holmes thing
is an instance of universal cognitive tool for re-arranging things according to a certain triadic structure of integration-disintegration-reintegration (a structure which works through the thinker, to realize itself) then an adequate 'meta-philosophical- perspective wouldn't seek to impose that structure over the whole history of philosophy (which seems like a response to the thinker's own personal shocks) but see the particular ways in which each epoch worked through that structure with regard to their specific shock, and the particular materials they had to make sense of it.
@180 ProofI guess this would be what you called 'nonphilosophical critique.'
5. It's hard, when breaking down things into epochs, not to see them as suggesting a new source, a center of stability, that organizes everything else. Plato has a fixed elsewhere. Newton's laws involve a fixed progression of matter through fixed transformations. So on, and so on. There's always something you can return to, in thought, which will always be there, and explain the rest. Not explain, necessarily, but
organize. This still goes for Deleuze and whoever else. It's a kind of hearth.
6. Maybe the question to ask of metaphilosophy, to figure out what it is, is what it is it looking for and why?
7. At a certain point, I get a feeling like this all Dumbo letting go of his feather, slowly, through a series of of progressively more abstract transitional objects? I guess ala Wittgenstein's 'fly in the bottle' but with a little more empathy. Instead of a meaningless creature, meaninglessly stuck in a small bottle, you have a confused and earnest person slowly trying on new ways of organizing things once and for all, until letting go and cultivating their own ability to organize with others, in their particular situation. (but then this too seems to be an overhasty wrap-up of it all?)
