The view for which McGinn is known is a jejune prediction, namely that science cannot ever solve the problem of how the brain produces consciousness. On what does he base his prediction? Flimsy stuff. First, he is pretty sure our brain is not up to the job. Why not? Try this: a blind man does not experience color, and he will not do so even when we explain the brain mechanisms of experiencing color. Added to which, McGinn says that he cannot begin to imagine what it is like to be a bat, or how conscious experience might be scientifically explained (his brain not being up to the job, as he insists). This cognitive inadequacy he deems to have universal epistemological significance.
Alongside the arrogance, here is one whopping flaw: no causal explanation for a phenomenon, such as color vision, should be expected to actually produce that phenomenon. Here is why: the neural pathways involved in visually experiencing color are not the same pathways as those involved in intellectually understanding the mechanisms for experiencing color. Roughly speaking, experiencing color depends on areas in the back of the brain (visual areas) and intellectual understanding of an explanation depends on areas in the front of the brain.
Now what does this snark and misdirection have to do with anything McGinn actually maintains? Nothing that I can see. Here's McGinn:
Churchland’s account of my arguments for our cognitive limitations with respect to explaining consciousness bears little relation to what I have written in several books, as anyone who has dipped into those books will appreciate. What she refers to as a “whopping flaw” in my position (and that of many others) is simply a complete misreading of what has been argued: the point is not that having a causal explanation for a phenomenon should produce that phenomenon, so that a blind man will be made to see by having a good theory of vision. The point is rather that a blind man will not understand what color vision is merely by finding out about the brain mechanisms that underlie it, since he needs acquaintance with the color experiences themselves.
Churchland 0 – McGinn 1.

A Sketch of the Difference between Two Ontological Styles
What it is for a thing to have a property? Ostrich nominalism aside, it is a Moorean fact that things have properties, but the nature of the having is a philosophical problem. The ordinary language 'have' does not wear it correct ontological analysis on its sleeve. My cup is blue. Does the cup have the property of being blue by standing in a relation to it — the relation of exemplification — or by containing it as an ontological or metaphysical part or constituent? The root issue that divides constituent ontologists (C-ontologists) and those that N. Wolterstorff calls, rather infelicitously, "relation ontologists" (R-ontologists) is whether or not ordinary particulars have ontological or metaphysical parts.
C-ontologists maintain that (i) ordinary particulars have such parts in addition to their commonsense parts; (ii) that among these ontological parts are (some of) the properties of the ordinary particular; and (iii) that the particular has (some of) its properties by having them as proper parts. R-ontologists deny that ordinary particulars have ontological parts, and consequently deny that ordinary particulars have any of their properties by having them as parts. Of course, R-ontologists do not deny that (most) ordinary particulars have commonsense parts.
Drawing on some graphic images from D. M. Armstrong, we can say that for C-ontologists ordinary particulars are "layer cakes" while for R-ontologists they are "blobs." 'Blob' conveys the idea that ordinary particulars lack ontological structure in addition to such commonsense structure as spatial structure.
The distinction between these two styles of ontology or two approaches to ontology is not entirely clear, but, I think, clear enough. To take an example, is the blueness of my blue coffee cup an abstract object off in a platonic or quasi-platonic realm apart and only related to the cup I drink from by the external asymmetrical relation of exemplification? That, I take it, is van Inwagen's view. I find it hard to swallow. After all, I see (with the eyes of the head, not the eye of the mind) the blueness at the cup, where the cup is. Phenomenologically, I see (some) properties. So some properties are literally visible. No abstract objects (as PvI and others influenced by Quine use 'abstract objects') are literally visible. Ergo, some properties are not abstract objects.
Here is a second argument. Some properties are either wholly or partially located at the places where the things that have the properties are located. No abstract objects are either wholly or partially located at the places where the things that have the properties are located. Therefore, some properties are not abstract objects. So I am inclined to say that the blueness of my cup is in some unmereological and hard-to-explain sense an ontological proper part or constituent of the cup. It is obviously not the whole of the cup since the cup has other properties. Ordinary particulars are not ontologically structureless 'blobs.'
Needless to say, these two quick little arguments do not decide the matter in favor of C-ontology. And the other arguments I could add won't decide the matter either. But taken cumulatively these arguments give one good reason to reject R-ontology.
It is also worth observing that an ontological constituent needn't be a property. Gustav Bergmann's bare particulars and Armstrong's thin particulars are ontological constituents of ordinary or 'thick' particulars but they are not properties of those particulars. The materia signata of the Thomists is a constituent of material particulars, but not a property of such particulars. So, C-ontology is not just a thesis about properties and how they are had by the things that have them.
So much for ontological background. For more on the two ontological approaches, see my article, "Constituent versus Relational Ontology," Studia Neoaristotelica: A Journal of Analytical Scholasticism, vol. 10, no, 1, 2013, pp. 99-115. Now what relevance does this have for the classically theist doctrine of divine simplicity (DDS)? But first: What is DDS?
The Doctrine of Divine Simplicity
To put it as 'simply' as possible, DDS is the thesis that God is without (proper) parts. (If you want to say that God is an improper part of himself, I'll let that slide.) Being without parts, God is without composition of any sort. It is obvious that God is not a region of space, nor does he occupy a region of space. So he cannot have spatial or material parts. If God is eternal, then he cannot have temporal parts. (And if there are no temporal parts, then God cannot have them even if he is everlasting or omnitemporal.) But he also lacks ontological parts. So the divine attributes cannot be different parts of him in the way that my attributes can be different parts of me on a C-ontology. We can put this by saying that in God there is no real distinction between him and his omni-attributes. He is each attribute, which implies that each attribute is every other attribute. Indeed, there is no distinction in God between God and any of his intrinsic properties. (Each omni-attribute is an intrinsic property, but not conversely.) What's more, there can be no distinction in God between essence and existence, form and matter, act and potency. Since God is in no way composite, he is simple.
And why must God be simple? Because he is absolute, and nothing absolute can be depend for its existence or nature on anything distinct from it. An absolute is what it has. It cannot be compounded of anything that is not absolute or dependent on anything that is not absolute. Why must God be absolute? Because anything less would not be God, a worship-worthy being. These answers are quick and catechetical, but I must invoke my blogospheric privilege and move one.
Plantinga's Critique Misses the Mark
Perhaps the best-known attack on the coherence of DDS is that of A. Plantinga in his Does God Have a Nature? The attack fails because Plantinga foists on the DDS an R-ontology that is foreign to the thought of DDS defenders. If properties are abstract objects, and God is a concrete particular, then of course it would be incoherent to maintain that God and omnsicience are one and the same. For if omniscience is a property, and properties are abstract objects, and abstract objects are causally inert, then the identification of God and omniscience would either render God causally inert — which would contradict his being concrete — or it would render omniscience causally active — in contradiction to its being abstract. More simply, if you think of concreta and abstracta as denizens of radically disjoint realms, as R-ontologists do, then it would be something like a Rylean category mistake to maintain that God is identical to his properties.
More simply still, if God is causally active and no property is causally active (or passive for that matter), would it not be supremely stupid to assert that there is no distinction in reality between God and his properties? Could Augustine, Anselm, Aquinas, Avicenna, et al. have been that stupid? I don't think so. Aquinas was as little Quinean in his understanding of abstracta as Quine was Aquinian. Philosophical theologians under the spell of Quine such as Plantinga and van Inwagen are not well situated to understand such tenets of classical theism as DDS.
It is obvious, then, that DDS is incoherent when read in the light of R-ontology. It is also uncharitable in excelsis to read Aquinas et al. in that light because so reading them makes nonsense of what they say.
Does C-ontology Help with Coherence?
One of the entailments of DDS is that God does not exemplify his nature; he just is his nature. We have seen that this makes no coherent sense on (any version of) R-ontology. But it does make coherent sense on (some versions of) C-ontology. For if God is purely actual with no admixture of potency, wholly immaterial, and free of accidents, then what is left for God to be but his nature? To understand this, one must bear in mind that the divine nature is absolutely unique. As such it is not repeatable: it is not a universal. It is therefore unrepeatable, a particular. What is to prevent it from being identical to God and from being causally active?
If you say that God is an instance of a multiply exemplifiable divine nature, they you are simply reverting to R-ontology and failing to take in the point I just made. God cannot be an instance of a kind, else he would depend on that kind to be what he is. God transcends the distinction between instance and kind. And if you persist in thinking that natures are causally inert abstract objects, then you are simply refusing to think in C-ontological terms.
If you say that I beg the question against the denier of DDS when I say that God transcends the instance-kind distinction, then you miss the point. The concern here is not whether DDS is true or whether there are non-question-begging arguments for it; the concern is whether it makes coherent sense as opposed to being quickly dismissable as guilty of a category mistake.
Another objection one might make is that the divine nature is not simple but complex, and that if God is his nature, then God is complex too. For Plantinga, the nature of a thing is a conjunctive property the conjuncts of which are those properties the thing exemplifies in every possible world in which it exists. On this approach, the divine nature is 'cobbled together' or constructed out of God's essential properties. But then the divine nature is logically and ontologically posterior to those properties. Clearly, no defender of DDS will think of natures in the Plantingian way. He will think of the divine nature as logically and ontologically prior to the properties, and of the properties as manifestations of that unitary nature, a nature the radical unity of which cannot be made sense of on Plantinga's approach.
There are other problematic entailments of DDS. One is that in God, nature and existence are one and the same. On an R-ontology, this makes no coherent sense. But it can be made sense on a C-ontological approach. A fit topic for a separate post.
My referrers' list points me to this post whence I snagged these two delightful quotations:
The pipe draws wisdom from the lips of the philosopher, and shuts up the mouth of the foolish; it generates a style of conversation, contemplative, thoughtful, benevolent, and unaffected.
William Makepeace Thackeray
A pipe is the fountain of contemplation, the source of pleasure, the companion of the wise; and the man who smokes, thinks like a philosopher and acts like a Samaritan.”
Edward George Bulwer-Lytton
The name 'Bulwer-Lytton' rings a bell doesn't it? You guessed right: it's the same Bulwer-Lytton who penned, in prose of purple, the opening sentence,
It was a dark and stormy night; the rain fell in torrents — except at occasional intervals, when it was checked by a violent gust of wind which swept up the streets (for it is in London that our scene lies), rattling along the housetops, and fiercely agitating the scanty flame of the lamps that struggled against the darkness.
Jean-Paul Sartre put the following into the mouth of a character in the play, No Exit: "Hell is other people." What then would hell be for philosophers? To be locked in a room forever with a philosopher with whom one has little or no common ground. David Stove and Theodor Adorno, for example. Or Sartre and Etienne Gilson.
Leftists are not concerned with the truth, but with the 'narrative.' The latter concern is animated by the will to power, not the will to truth, a fact that explains what otherwise would be hard to explain, namely, why certain leftists are enamoured of Nietzsche. Here are the liberal narratives with respect to Bergdahl, Benghazi, IRS, Obamacare, VA, and illegal immigration. Excerpt:
For the Obama administration narrative to be accurate about the swap of five Taliban/al-Qaeda-related kingpins for Sgt. Bergdahl, we are asked to believe the following:
1. Sgt. Bergdahl was in ill health; thus the need for alacrity. Surely we will expect to see him in an enfeebled state on his return to the U.S.
2. Sgt. Bergdahl was in grave and sudden danger from his captors; thus the need for alacrity. We expect to see proof of that on his return to the U.S.
3. The five Taliban detainees will be under guard in Qatar for a year. We expect in June 2015 to know that they are still there in Qatar.
5. Sgt. Bergdahl served with “honor and distinction.” We expect to have confirmation of that fact[4] once his intelligence file is released and more evidence is adduced that all of his platoon-mates were wrong (or perhaps vindictive and partisan[5]) in stating that he voluntarily left their unit — deserted — to meet up with the Taliban.
6. Sgt. Bergdahl was captured on the “field of battle”; we expect to have confirmation that he was taken unwillingly by the enemy amid a clash of arms.
7. Sgt. Bergdahl was not a collaborator. We expect to learn confirmation of the fact that he did not disclose information to his captors.
8. Bergdahl’s fellow soldiers in his platoon are either partisan operatives or sorely misinformed, and we will shortly learn that their accounts of Bergdahl’s disappearance were erroneous.
9. The U.S. has traditionally negotiated to bring home even deserters, and did so frequently, for example, both during and after the Korean War when GIs crossed into North Korea.
11. There is no law stopping the president from releasing terrorists from Guantanamo, only legal fictions[7] promulgated by right-wing critics of the president.
12. The five Taliban terrorists are now old outliers[8], rusty, and mostly irrelevant to the war in Afghanistan.
Hilary Putnam took up blogging on 29 May of this year. Well, better late than never. He has entitled his weblog Sardonic Comment. He might also have considered It Ain't Obvious What's Obvious, which is a line he uses somewhere.
In 1976, when I delivered the John Locke Lectures at Oxford, I often spent time with Peter Strawson, and one day at lunch he made a remark I have never been able to forget. He said, "Surely half the pleasure of life is sardonic comment on the passing show". This blog is devoted to comments, not all of them sardonic, on the passing philosophical show.
Here: "THE YOUNG man accused of stabbing Esa Saarinen, a professor of applied philosophy at Aalto University, has revealed that his objective was to whip up media attention."
Ken Hochstetter of the College of Southern Nevada kindly sent me some comments on my SEP Divine Simplicity entry. They are thoughtful and challenging and deserve a careful reply. My remarks are in blue. I have added some subheadings.
The editors of the Stanford Encyclopedia of Philosophy want me to revise my Divine Simplicity entry by July 2nd. Written in 2006, it has been revised once, in 2010. This will be the third revision. If anyone who knows this subject has any constructive comments on the style, content, coverage, or organization of the present entry, I'd like to hear them. In particular, references to recent literature not included in the present bibliography would be helpful.
