That is exactly what I mean when I say you're redacting out some aspects of their thinking, so as to incorporate the aspects of it are useful for your approach. — Wayfarer
But it's not me who is trying to pin a single reading on what Peirce, Hegel or Aristotle "really meant" as if they were my spokesmen or my authorities.
I'm quite happy with the fact they were all complex thinkers whose own views evolved considerably over their lifetimes and so involve views that were in contradiction, or even - in my view - quite off the mark. at times.
Furthermore, Peirce was different as a philosopher in having a scientific attitude to his speculative cosmology. So the changes in his approaches can be viewed as a series of goes at striking upon the right formulation - one that would actually result in testable outcomes. In rejecting Newton's mechanical paradigm, he actually started proposing ways of checking to see if the geometry of the Universe was flat rather curved.
TL Short in What was Peirce’s Objective Idealism? 2010, makes the argument that his use of the term objective idealism marks only a phase in his thinking - one of his goes at making a developmental cosmology work. He tried it for a few years and moved on.
Now that is probably too strong. But I think we have to really examine the technicalities of Peirce's conjectures rather than simply flourish the comments where Peirce sounds enthusiastic about Emerson (a family friend) and Schelling.
Key here is Gaudiano's summary of the contrast between a materialistic and idealistic ontology...
(B) the psychical law as derived and special, the physical law alone as
primordial, which is materialism; or,
(C) the physical law as derived and special, the psychical law alone as
primordial, which is idealism. (EP1 292).
So as I say, Peirce tried to account for the cosmos in terms of "psychical law". And by that, he doesn't mean the application of some theistic or dualistic notion of mind, spirit or soul. He actually means the current psychology of his day. Remember that he was close to James. And he himself did foundational work in the application of the scientific method to psychological research.

If you google for the link to Short's paper, What was Peirce’s Objective Idealism?, you can see the rather science-informed description of "the mind" that Peirce was applying to his cosmology. And it is basically the usual constraints-based system thinking I'm always talking about. So it is my claim here that "mind" boils down to "psychical law", which boils down to what I mean by organicism or systems casuality.
So as Short notes, Peirce was talking about habit-formation as being the critical dynamical process. And this led him to taking a rather odd, probably frankly self-contradicting, approach to consciousness or attentional level mental proocessing.
So for most people - especially when they think of idealism - they think it is all about the ineffable phenomenological aspect of "being conscious". That is the basis of Cartesian dualism - the apparently inescapable fact that there is something which it is like to be me, or you, or a bat. And then when Peirce starts talking about matter being effete mind, the natural assumption is that he means - panpsychically - that material substance is some kind of very dilute or deadened version of a mental substance.
Yet Peirce talks about consciousness quite differently as Firstness (where habit is Thirdness). So consciousness is associated with the brief fluctuations that are breaks in the smooth (unconscious!) running of habits. And this leads to a reversal of what you might expect.
Peirce's idea is that the cosmos started in a chaos of fluctuations and developed then the regularity of habit. And so the character of this beginning was of the kind of vivid, but undigested, consciousness of the newborn where all is a Jamesian blooming, buzzing confusion. Conscious feeling was at its most intense because absolutely everything is a disorganised surprise. But then also it was at its most chaotic or vague because it was nothing but a flood of disorganised surprises.
So what Peirce means by mind is the steady organisation which imposes order on raw feelings, or wild fluctuation. Law is the emergence of habit. A gradual suppression or constraint on surprise because the mind comes to read events in terms of signs that it interprets. We know that the beep of a car horn or the hand on the shoulder is an understood part of a world with an order. It is another example of that category of thing.
And Peirce was also careful to say he was not talking about individual minds, but the world as if it were a mind ruled by the psychical laws that psychology was establishing. Human minds are the product of neural complexity - Peirce knew that. So his argument was that they retain a lively capacity for surprise - for the flashes of attention that is the first experience of something novel - that then allows for the continual formation of new habits.
And if you follow his analysis of protoplasm, you can see how he hopes to argue a continuity from the extreme liveliness of human material organisation, through to the self-organisation of protoplasm, and eventually towards the now minimal - effete, extinct, dead - liveliness of the cosmos itself. The cosmos that is so past lively flashes of spontaneous thought that it lives as a collection of dry mechanical habits.
Importantly, Peirce point about protoplasm was the thermodynamic one. Thermodynamics had explained existence in terms of an entropy principle. And that made negentropy - the emergence of cosmic organisation a real problem. Even worse for Peirce's developmental cosmology, this new mechanical notion of entropy said the cosmos must begin in a state of high order, and his chaos is what comes at the end in a heat death.
So Peirce was wanting to say no. The ancient's had it right with their organicism. First there was an endlessly lively chaos, then this developed constraints to produce the well organised, very habitual, cosmos we see around us today. And so Peirce foresaw what was eventually proven by Prigogine. Boltzmann's mechanical version of thermodynamics is simply the reduced and deadened version of the livelier thermodynamics of modern dissipative structure theory. And cosmologists like Layzer have been championing a developmental cosmology as a consequence.
Anyway, the point is that when Peirce speaks about a cosmic mind, he means one actually ruled by psychical law and so one in which the key fact is not the emergence of consciousness - a surplus of feeling - but instead about the constraint or suppression of that in order to produce the regularity of habits.
As Short stresses, his objective idealism focuses on the principle of generalisation. Peirce is saying that lawfulness or habits develop via the "spreading" of a confusion of sharply felt instances. Over time, the differences fall away and some commonality emerges - a conception, a schema, a category, a universal. And this comes to encode a constraint on variety. It comes to encode the top-down formal and final purpose that constitutes the being of a habit, with its regulative effect on lively spontaneity.
So you do have a very difficult bit of philosophy here. But what is clear - in my opinion - is that while it sounds like Peirce is simply doing the easy thing of making panpsychic proclamations - the Universe is made of mind stuff - you really have to pay attention to the technical detail of how he really intends to cash out his objective idealism. And there he starts to talk about mechanical/material laws vs organic/psychical laws.
So - as is the case with modern biosemiotics - he really is focused on trying to fix the shortcomings of reductionism by bringing in four causes Aristoteleanism. He is saying life and mind do show there must be more to nature than a mechanist's conception of reality as a clutter of blindly bumping lumps, a rain of atoms in a void. And psychical laws - the story of habit formation in living beings right from humans down to protoplasm - capture the essence of that.
So it is not that nature has phenomenological experience everywhere in some degree - the panpsychic position. It is that nature everywhere is organised by this common "psychical" principle of habit-formation or the universal growth in reasonableness.
You could say in this light that matter is effete mind in having gone right to the extreme of being so habitual as to be deterministic. And humans - because of their complex organisation - are instead a lively balance of feeling and habits. Humans have huge capacity for development in their own lifetimes.
After his objective idealism phase, Peirce did continue to develop his semiotics more fully, which is why I personally would describe his ultimate goal as pansemiotics. If you can drop the apparent appeals to phenomenological experience - Peirce was quite plain he was against this dualistic reading - then you are left with his emphasis on a commonality of a semiotic mechanism. It is the way that minds work - by generalising away a chaos of fluctuating feeling to arrive at the intelligible regularity of habit - which is the insight he wanted to apply to a developmental metaphysics of existence itself.
