It's as if most reasoning proceeded on the basis of a bait and switch between learned stuff summarised and internalised and really existent abstractions. But it looks like a real relation between these two is denied? Dunno. I imagine this is similar to apokrisis's perspective in some ways. — fdrake
I am a meaning holist. So on the face of it, Sellars' move seems objectionably nominalist. It treats even wholes as always particular. But then it also look to says that wholes are not composed of general parts. So it may be a tactic for revealing the essential inversion that is at the heart of true holism.
Look at the parts and you discover the wholeness. Look at the whole and you discover the partness. Relations need relata, and conversely, relata need relations. Nominalist and Platonists both get it wrong to the degree that they can't give us a clear view of this reciprocal dynamic that maps the particular to the general, the general to the particular.
So what do I think about the reality of abstracta? I take the hierarchy theory view - as set out by Stan Salthe in particular. The abstract now becomes the regularities that persist, that become fixed, due to the semiotic effects of spatiotemporal scale.
So rather than abstracta being transcendent - either actually transcendent forms, as in Platonism, or transcendent constructs, as in nominalism - they are an immanent fact about a material world that has spatiotemporal scale, a world that is organised as a hierarchy of "cogent moments".
Salthe gives a simple model of how it works. Imagine a world of entities of similar size. Now imagine the same motifs or integrative processes being repeated freely at both smaller and larger sizes. We have our regular size blobs - the entities that are about the same size as us, and so they they look like other distinct things. But as these blobs grow larger and larger in relation to us, they begin to fill our field of view.
Eventually, a single blob is so large that it exceeds our vision and becomes the complete unchanging backdrop. It is everywhere at all times, so far as we are concerned. It is no longer particular, but completely general - simply due to spatiotemporal scale and the fact we are confined to a point of view concerning entities.
This creates the upper bound of a hierarchical world. Individuated particulars - even ones that are processes unfolding in space and time - eventually must turn into global generalities simply due to an unbounded growth that makes them too big to continue to be related to as individuated particulars.
So this is a model of how the abstract can, indeed must, arise in a world where entification is a thing, but also not an artificially bounded thing. If there is entification, it should freely be the case over all scales. As why not? And in that fact lies the corollary that scales of entification will eventually completely fill a point of view, crossing a relational event horizon so as to become a universalised property. A fact about the whole.
Then conversely, the same story applies when we look in the other direction - down towards the fractally shrinking scales of entification. Now the generic units that are composing existence are getting both smaller and more frantic. Their spatiotemporal integrative scale, or cogent moment, is becoming microscopic - from our point of view. Eventually it gets so small as to turn into a continuous blur, so far as we are concerned. It all gets too small for us to have a relation to it as a set of discrete elements.
So now we have a complementary realm of abstracta bounding our entified existence. Purely for immanent and natural reasons - the fact that we are observing things from a characteristic scale of entification - both largeness and smallness become the congealed bounds, the event horizons, which come to fix our existence.
We live within the holism of whatever is the spatiotemporal scale that is so large it completely fills our point of view. And also, we are supported by the solidity of the spatiotemporal scale that is so fast and busy that we can't slip between its cracks.
So the abstract is both emergent and real. And it lies in two complementary directions to the particularity or individuation we find all around us - at a similar enough scale of entification.
And of course this hierarchy theory story is Peircean.
The lower bound of reality is the fast/small scale of chance events or Tychism. The realm of the differences that no longer make a difference. The realm of the quantum indeed - when viewed from the distanced safety of the classical middlescale.
The upper bound of reality is the slow/large scale of inveterate habit, or the continuity of Synechism. Now difference is eliminated not by indifference or contingency, but by the growth of universal necessity. All other possibilities have been eliminated. We live within the one unbroken totality - as now general relativity aims to describe.
So to get back to meaning holism, my point is that nominalism vs Platonism is a very familiar dualistic battle. It seems one or other side needs to win.
Yet a pragmatist view - and Sellars is meant to be very close to Peirce, even if it seems to have come via Dewey - really ought to be able to home in on the reciprocality of parts and wholes. The point about local vs global, particular vs general, is that they are just the same thing - divided by an asymmetry of scale.
So ordinary language and predicate thinking wants to work from the bottom up, constructing holistic complexity from substantial parts. However we know that zoom in on the parts and they themselves will keep dissolving into further parts. It is only by keeping our proper distance - preserving the larger thing of the semiotic relation we have with them - that they will remain that solid blur protected by indifference. The predicate approach will function so long as we don't actually look down.
But equally, holism is suspect in its claims of being able to form its world from the top-down, just by the imposition of Platonic constraints of form and purpose. Zoom in on the wholeness and it will be revealed as in fact just another particular. We get the usual story of a totalising physical theory that instead explodes into an unbounded multiverse. Again, it is the semiotic relation that is the only thing holding everything together.
An accurate description of reality, a language that captures its structure in terms of particulars vs generals, has to learn how not to treat the global as a Platonic reality, but just an event horizon that - like a mirage - exists because we are maintaining a suitable distance from it.
So holism - of this kind - is irreducibly triadic. (Salthe did dub his model the basic triadic structure. His book on this - Evolving Hierarchical Systems - is essential reading.) We exist in world of stable objects - the medium-sized dry goods of a classical realm - because any instability is being regulated from both possible directions.
From below, the instability might grow more violent as the scale shrinks, but it also becomes so microscopic as to be indifferent - to us. The "partness" both increases and also ceases to matter.
And conversely, looking up, any instability disappears. Scale makes change too slow have an effect. For us, universal law becomes the rule - even though now this "wholeness" starts to look rather particular. It has become "everything that is the case". A singular totality that we can no longer rightfully decompose into predicate parts.
So when it comes to speech and its efforts to logically frame our experience of reality, we can see how it actually wants to target the critical instabilities of the world at our scales of interest. What gives us the most practical information is the distinctions that give names to the points where this instability~stability dynamic is poised right on its cusp.
Are we talking about a part or a whole? Well, what is most useful is to talk about entification which is right on the brink of going either way. As that is the kind of talk which gets at the actual deep structure of the world.
The relata are the stable elements, says reductionism. The relation is the instability, the potential transformation. But then conversely, all relata, all elements, are themselves not entities but processes, says holism. What is solid and eternal are the relations, the structure, the organisation.
Hmm. A contradiction or instead just complementary views? The same critical instability seen from opposite directions?
Sure we can dispense with predicates to emphasise one of the views. And then - which seems to be Sellars' intent - we discover the nominalism that can be found inside holism. Just as holism finds nominalism within itself when it does its own naming of abstracta, its own naming of absolute generalities.
Again, the art of language would be to be able to put a finger on the hinge points - the place where the interesting flips happen.
This horse is white. Whiteness is generic. Here we have put our finger on an instability that orientates us to the way the world really is in its game between what is necessary, what contingent, or what is general, what particular.
Entities both hang together and fall apart. Language - with a predicate syntax, yet also a sentential holism of interpretation - gets that.
Chomsky was at least right about the recursive hierarchical organisation of speech. The unit of comprehension is not the syntactic particle. It is already the irreducible thing of a semantic entity framed syntactically by an above and a below. It is a word phrase that is indifferent to finer distinction, and stabilised by the constraint of the larger meaning intended. The words are detailed or particular enough for ambiguity to be grammatically ignored, while the words are also bounded enough by the habits of whole sentence-making to count stably as a compositional semantic unit.
Zoom in or zoom out, and all this stability falls apart. But keep everything the right distance and it hangs together for long enough to achieve a pragmatic goal.
And that is meaning holism. The emergent stability which underpins entification.
