As I noted at the top of my Amazon review (see inclusion below), Hogan’s “Austere Realism” and Graham Harman’s “Object Oriented Ontology” are, near as I can tell, exact inverses of one another. Harman’s view is that everything is real, everything is an object. Every star, planet, building, book, nation, thought, and all their relations, a virtual infinity of relations between everything and everything else taken individually and in sum. “All objects”. Horgan’s view it the exact inverse. For Horgan there is only one ontologically genuine concrete object in the universe, that being the universe taken as a whole, across all time, what he calls “the blobject”.
Both theories, in their own way, amount to saying the same thing. Whether “all is one” or “literally everything is an object”, both declare that “everything is the same”. On a strictly ontological level, there is no distinction to be made anywhere. This is not to say that the two theories say the same thing, not at all. But because they are both at the extreme ends of the metaphysical spectrum they both collapse all distinction and end up explaining nothing.
Horgan doesn’t mention Harman; not in the book nor the copious end notes. None of Harman’s books are even listed in the bibliography. I am surprised. Although the polar opposite of Horgan’s ontology, I would think the common feature of “being at the extremes” of ontological speculation would be worth a mention. I have dealt with Harman in several book reviews and essays here on the blog. Now it is Horgan’s turn.
In my review I do point out that Horgan’s book has two purposes; to set forth his “blobjectivism” and to show how, even if there is but one concrete particular in the universe (the universe itself) this idea is perfectly consistent with talk about a multiplicity of objects. “The United states dollar is the primary reserve currency on Earth” is true even though “the United States”, dollars, currency, and “the Earth” do not strictly exist. The same is true for more purely physical assertions. “Mars is the fourth planetary orbit outward from the sun” is true though there is no Mars, planets, orbits, or the sun. These statements can be true because their truth lies in semantic contexts that only “indirectly correspond” to some as yet unspecified phenomena of the “mind-independent world”, something both Horgan and Harman must accept as real or they wouldn’t be “realists” at all.
It is the social construction of language and so the presence of varying semantic contexts that make such statements true. They are true not because the things they purportedly reference (planets, money) exist, but because they meet the semantic standards of speech concerning posits about distinctions that exist only in a mind-dependent way. This connection between ordinary speech and ontology is a nice touch, but what is it about these “pseudo object posits” that makes them unreal ontologically speaking? Horgan points to vagueness (which he also calls boundarylessness) and the “Special Composition Question” introduced by a short detour through the work of Peter Van Inwagen. Much of this Horgan illustrates with what philosophers call “sorites problems” the most famous of which (and perhaps because of this Horgan doesn’t use it) is the “ship of Theseus”.
Theseus has a ship made from wooden planks. At some point one of the planks rots and must be replaced with a new piece of wood. Is it still the same ship? What if two planks are replaced, or ten, or all of them? Somewhere along the process some people would say that it is no longer the same ship though others would disagree. But the point is there is no definite point where the replacement of just one more plank makes a different ship. This observation suggests that the ship of Theseus (and most everything else) is vague and it is an axiom of Horgan’s ontology that “vague objects” do not actually exist as such. There is no such object as “the ship of Theseus” even though Theseus (who also does not exist) is plainly sailing in something.
The “special composition question” is related to this but has to do with what is and is not a proper part of a larger construct. Does a chair (some chairs) have parts? Does it have legs, a back, a seat, and perhaps arms? The chair is subject to sorites issues; if I remove a leg and replace it with another is it the same chair? But also we notice that legs, arms, seats, and backs, not to mention chairs, are all made of atoms. Perhaps the only real parts of anything are the atoms. A chair (Van Inwagen’s famous example) is nothing but “atoms arranged chair-wise”. It has no other proper parts because they are all merely atoms arranged leg-wise, seat-wise and so on.
So what does Horgan say is the chair in the mind-independent world? He says it doesn’t exist. It is not a “proper part” of the universe. Instead, what he believes, is that the blobject, the whole universe just is in some particular spatiotemporal location arranged chair-wise. Instead of a composition from atoms on up, the key insight for Horgan is that the differentiation goes from the top down. The mind-independent “whole universe” happens to be differentiated into everything that we take to be mind-independent about the world and according to Horgan (he is explicit here) this differentiation is both real and precise; not vague.
Yet, since the blobject is differentiated into something or other not-vague (chair shaped, rocks in orbits, suns, gas clouds, radiation) literally everywhere, and all of these differentiations have effects (gravitationally or otherwise) on other differentiations around them, how is saying what Horgan says any different from saying that all of the differentiations, taken mind-independently, are simply real objects with a genuine compositional structure? If the blobject’s everywhere differentiations are not vague, where comes from that vagueness he uses to insist that suns, rocks, gas clouds, and chairs don’t really exist? If the blobject differentiates precisely and the differentiations are mind-independent, the vagueness can only come from what is not mind-independent, namely the machinations of mind both pre-linguistic and linguistic!
The problem comes fully around to bite Horgan when he speculates on mind itself. If there is mind in the universe, the blobject also is differentiated spatiotemporally into minds! Mind itself, our phenomenology taken as a whole (Horgan suggests) is also a differentiation of the blobject and for that reason precise, though the contents of any given mind, for example propositions, can still be vague. But even with this little escape for vagueness’ sake, Horgan seems committed to mind-independent mind!
This result does not appear to have given Horgan any pause, but I think it is enough to show that there are difficulties with his view he does not address in the book. In the end philosophy is always trivially right when it takes positions at the extremes of ontology or epistemology. One cannot in the end refute a pure idealism, nihilism, solipsism, or a realism that says, one way or another, that “everything is the same”. In the end Horgan is not wrong. Nor is Harman. But Blobjectivism, like Object Oriented Ontology, is a difference that makes no difference! As concerns the “mind-independent world” saying everything, including all properties, are localizations of the blobject is the same as saying that all the localizations are real and exist. As goes ontology, Horgan (though not Harman) need not worry about baldness, nations, money, or even language since none of these phenomena are strictly mind-independent.
Interestingly this book is a counter point and the ultimate theory is exactly the inverse of Graham Harman’s “Object Oriented Ontology” (see my reviews of various Harman books). Ironically, the universality of their views cause both philosophers the same problem. If what exists is univocal (everything is an object [Harman] or there is only one object [Horgan]) you explain everything while explaining nothing. However delving into such philosophical matters is not the purview of a book review and I will talk more about this in my blog. Meanwhile, one of my criticisms of Harman is that he never really tells us why or how he came to his position, a complaint I cannot level at Horgan as that telling is the very purpose of this book.
Horgan first introduces us to realism in general and then austere realism. He spends roughly one third of the book (at the beginning and again at the end) characterizing austere realism and in particular his version of it, something he calls “blobjectivism”. Roughly two thirds of the book he spends not on his ontological theory as such but on how that theory relates to statements in ordinary and scientific discourse. If we want to say that planets, stars, buildings, and nations do not exist, how is the scientific statement “Earth occupies the third orbit outward from the sun” or the economic observation “the U.S. dollar is the world’s primary reserve currency” true? He says such statements are true not because the “objects” they purportedly name exist, but because talk of these categories only “indirectly corresponds” to the mind-independent world. The indirection goes through the process of conceptualization.
Much of the book is an exposition of this process works; how it is that many statements in ordinary and scientific discourse can be true even though the objects they purportedly talk about do not really exist. His direct argument for their non-existence has to do with vagueness, what he also calls the boundarylessness of discursive subjects, and the related “special composition question”. In stipulating a mind-independent world he also stipulates that no mind-independent object can be vague or boundary-less. Vagueness can always be made to look inconsistent. He gets into this issue by introducing what philosophers call “sorites problems” (take a man with 5000 hairs on his head. If I take away 1 hair is it still the same man? And this is only the beginning of a sorites problem). Anything we might call “an object” within the universe is subject to this sort of breakdown. Horgan insists that this being so, none of these postulated things exist in the mind-independent world. Objects of the mind-independent world cannot be intrinsically vague.
Horgan slides between mind-independence that cannot be vague, and discourse following general and not-fully-specifiable linguistic standards (themselves vague), to what he calls the vagueness of linguistic posits about the world. The problem here, the problem Horgan doesn’t seem to see, is that all the vagueness is mind-dependent. There isn’t any vagueness about the man with 5000 hairs in the mind-independent world. The vagueness enters only when mind directs itself at analyzing the concept of that man. Horgan is quite correct I think in that all that is mind-dependent is vague. I believe this is necessarily so, though Horgan does not (and says so). Nevertheless these indirectly corresponding posits cannot be real though propositions about them can still be true. Besides introducing us to the blobject, the point of the book is the [mind-dependent] connection between Horgan’s ontology and the correctness of ordinary talk thanks to semantic context and indirect correspondence.
To my mind, Horgan fails to appreciate some of the implications of his ontology. For him, the stuff of the mind-independent world are not parts of something greater but rather spacetime localisations, differences, of “the one concrete particular that exists”, the blobject. If this is the case, and he says this, these spatiotemporal localisations must be precise, not vague! There are many issues arising here I will leave for another venue (see my blog), but the bottom line is that if they are not vague we might as well call them objects! It isn’t that Horgan is wrong (let’s say). It isn’t that ontology cannot be as austere as he claims. But it doesn’t matter. Giving an inch here is worth a mile. If spatiotemporal variations in the blobject are real and precise then conceptualizing those variations as objects, saying “they exist” and “directly correspond” (in Horgan’s semantic scheme) to mind-independent particulars amounts to saying the same thing.
Still all in all Horgan does a great job putting this together. I gave the book four stars not because of philosophical issues but because Horgan’s writing is not as clear as it might be. There are many long sentences with multiple and parenthetical clauses. Sometimes his argument is a little difficult to follow. But what was worse, the Kindle version of this book (the version I have) has a serious problem! This is not the author’s fault. The publisher was way too casual with this conversion. There are a lot of end notes in this book. A considerable amount of detail in the author’s exposition is in the end notes! But while the notes are flagged in the text, flags are not made into links. You cannot press on an end note and go to the note as as is conventionally the case in most of the Kindle books in this and other non-fiction genera. Such features are, after all, part of the point of e-books! This is a serious omission in a scholarly work like this, and makes the whole, if you really want to see the end notes as they come up, way more difficult than it should be.
