Top o’ the Stack.

Over lunch on Sunday, Brian B asked me to explain my disagreement with Ed Feser and others over Aquinas’ hylomorphism. Here is a pithier statement than the ones I’ve already posted.
I will assume with Aquinas that human beings after death continue to exist as disembodied souls until the general resurrection. The question I and others have posed is how the persistence of individual souls after death is conceivable on the Aristotelian hylomorphic principles to which Thomas subscribes. Why should this be a problem? The problem is that the following propositions, each of which is a doctrinal commitment of Thomas, are collectively logically inconsistent: they cannot all be true.
a) Designated matter in material substances both individuates their forms and accounts for the substances’ numerical difference. Thus Peter and Paul are two and not one because of the difference in their designated matter. And their forms are individuated by designated matter as well. This implies that (i) Peter’s substantial form is numerically different from Paul’s, and that (ii) neither form is an individual form without the matter that individuates it.
b) The souls of living things are substantial forms of their bodies: anima forma corporis. Peter and Paul are living things; hence their souls are individual substantial forms of their bodies. To put it more precisely, Peter and Paul are form-matter composites. The psychic or soulic component in each is the individual substantial form, and the material component in each is the parcel of designated matter. Each component needs the other to be what it is: the psychic-formal component needs the material component for its individuation, and the material component needs the psychic component for its animation. And neither component can exist without the other: each exists only together with the other. Thus the whole of which they are proper parts is not a whole compounded of parts that can exist on their own, as substances in their own right, but a whole the parts of which are mere ‘principles’ in scholastic jargon and thus not substances in their own right. This implies that the hylomorphic whole, which is a substance in its own right, is ontologically prior to the morphic and hyletic parts which are not substances in their own right. Bear in mind that a primary substance, by definition, is a basic entity that is metaphysically capable of independent existence.
c) The souls of humans, unlike those of non-human animals, are subsistent: they are metaphysically capable of independent existence. So the souls of Peter and Paul will continue to exist after their bodily death in a disembodied intermediate state prior to their re-embodiment in the general resurrection.
The triad is inconsistent because (a) and (b) taken together entail the negation of (c). Indeed any two of the propositions, taken together, entails the negation of the remaining one.
In a nutshell: it cannot be the case that souls depend on material bodies for their existence and individuation but continue to exist as individual souls after bodily death in a bodiless state.
What Thomists want to say is that SOMEHOW a substantial form that achieves individuation ‘here below’ pre-mortem by marriage with a hunk of matter, thereby animating said hunk of matter, continues to exist as a disembodied individual soul ‘up yonder’ post-mortem AFTER the individuating factor has been removed. That makes no sense. What would make sense is that the individual soul cease to exist after the death of the body. Bear in mind that the soul on an Aristotelian hylomorphic mereological analysis is a mere ‘principle’ of the hylomorphic composite entity and not itself a substance.
The conclusion to be drawn from this is that despite the Angelic Doctor’s noble attempt to stay as close as possible to The Philosopher (philosophus), he is in the end a substance dualist of sorts, though not quite along Platonic, Augustinian, or Cartesian lines.
There was a time when I thought that, with respect to the soul, Thomas was an Aristotelian ‘on earth,’ but a Platonist ‘in heaven.’ (I may have picked up that line from Anthony Kenny.) But then the problem of the SOMEHOW, the problem of how a human soul can go from a mere non-subsistent ‘principle’ to a subsistent upon the removal of the soul’s individuating factor, becomes insoluble. I now think that it would be better to say that, with respect to the soul, the doctor angelicus was a Platonist in both the sublunary and superlunary spheres, both ‘on earth’ and ‘in heaven,’ and this in consequence of his Christian theological commitments which exercise ‘veto power’ over his philosophical assertions.
Substack latest.
That philosophers disagree is a fact about which there is little disagreement, even among philosophers. But what this widespread and deep disagreement signifies is a topic of major disagreement. One issue is whether or not the fact of disagreement supplies a good reason to doubt the possibility of philosophical knowledge. Czech philosopher Jiří Fuchs says it doesn’t. I say it does.

Suppose all who are born will receive an utterly blissful, unending, afterlife. That’s quite a supposition, but just suppose. Add to this the reasonable assumption that one first comes to be at birth, or rather at conception: one does not pre-exist one’s conception either as an actual Platonic soul awaiting embodiment, or as a merely possible individual awaiting actualization. Two assumptions, then. The second assumption amounts to the claim that before one is conceived one is nothing at all.
Given the truth of both assumptions, had I never been born, I could not have missed out on any good things, in this life or the next, and this for the reason that one cannot be the recipient of any good if one does not exist. Call that the underlying principle.
To state the underlying principle in general form: Nothing can give, receive, have, lack, enjoy, or suffer any thing, action, property, or state unless it exists.
And so, although I am alive, and the good in my life preponderates and will (let us assume) continue to preponderate over the bad as long as I am alive, and I will receive eternal bliss from the moment of death on, I would not and could not have missed out on anything had I never been born (or rather conceived).
Is the underlying principle more reasonably accepted or more reasonably rejected?
Assume you agree that it is the former. Now consider someone whose life in this world is on balance very bad, but its badness will be more than compensated for by an eternity of heavenly bliss. Even so, it seems to me that it would have been better had this poor schmuck never been born, and this for the reason that, first, had he never been born, he would never have suffered the terrible things he suffered in this life, and second, had he never been born, he would not and could not miss out on anything good including transcendent goods that would have more than compensated him for his earthly suffering.
Examined and rejected. Top o’ the Stack.

Contemplating suicide? Look before you leap.
Julian Green, Diary 1928-1957, p. 230:
The yearning to leave the world is so strong at times that I don’t know how to resist it, but am nearly sure that this is the great temptation that must at all costs be warded off.
Christopher Rufo may have come up with the best analysis of the Fuentes phenomenon. He is, says Rufo,
. . . an essentially fraudulent phenomenon. He is a manipulator who pretends to believe in every evil in order to drive clicks, cause chaos, and achieve celebrity, even as a villain.
He has incited division on the Right. Some conservatives think that the kid should be ignored lest his views be legitimized. Others think his views should be debated and refuted. This conservative contretemps can be side-stepped once it is realized that what I called “his views” are not authentically his and put forth in good faith. So his false and contradictory statements, interspersed with some reasonable ones to add to the confusion, ought not be taken at face value. The guy is operating in
. . . what postmodern theorist Jean Baudrillard called “hyperreality”: a system in which the simulation of reality comes to replace reality itself. Under conditions of hyperreality, symbols of past phenomena lose their original meaning. Emptied out, they then circulate through digital media, where they drive the discourse and, while purely derivative, still spark real emotional involvement. In this way, the hyperreal becomes “more real than real,” masking the true nature of reality. [. . .]
The tone of his discourse is not authentic, serious, or reflective. It is ironic, cynical, and provocative. When Fuentes lauds Hitler and, in another interview, praises Stalin—irreconcilable ideological enemies—he is not expressing a comprehensible ideology that can be scrutinized in debate. He is engaging in a performance, which only becomes coherent when read as a demand for attention.
I would call it performative bullshit of the sort engaged in by Gavin Newsom with his “hand jive,” Kamala Harris, with her hyena-like risibility, “Tampon Tim” Walz, Swalwell, Cory Booker with his baseball bat, and other Democrat clowns. Nancy “The Shredder” Pelosi recently got into the act by tearing apart a fake crown in line with the mindless Faux-King meme. Trump has them completely under his control so much so that all they can do is flail about reactively with silly memes, endlessly repeated dealings of the race and Hitler cards, all the while saying nothing of substance and proposing nothing positive.
So the best response to Fuentes the political performance artist may well be no response at all. This too shall pass.
I’ll add one nuance to Rufo’s take: Fuentes is probably not fully self-transparent in his fraudulence. He knows not fully what he does. He is a confused kid who craves and receives attention, attention that has gone to his head; a kid mesmerized by the high tech that permits him to propagate his performances and baseless asseverations, but is also — let’s be fair — truly troubled by what troubles a lot of the Zoomers. They’ve been cheated by the abdication of authority on the part of parents, teachers, and clergy.
Which brings me to my last point: the Zoomers do have legitimate grievances, some of which have been mentioned in the previous comment thread.
The following is by James Soriano who does an excellent job of summarizing important points made by Dreher who, though prolix, is turning out good content on this and related topics.
………………………………
I link below a rambling essay by Rod Dreher on his visit to Washington, where he had a long conversation with VP Vance in the company of Hungary’s Viktor Orban on the future of Christianity in Europe and other things.
The essay goes into a long digression about the prevalence of Jews in certain walks of life, but at the end Dreher recapitulates the main points of his findings during his Washington visit.
I’ve shortened them and I would like to pass them along because they summarize the state of the civil war now raging in the ranks of conservatives. There is much to be pessimistic about.
1. The Groyper thing is real. It is not a fringe movement. It really has infiltrated young conservative networks.
2. Irrational hatred of Jews (and other races, but especially Jews) is a central core of it.
3. It cannot be negotiated with, because it doesn’t have traditional demands. It wants to burn the whole system down.
4. The gatekeepers of the Right can’t make it go away. They have less power than ever. Dealing with this is going to require great skill and subtlety, and courage.
5. This malign movement didn’t just appear from nowhere. There are within it legitimate grievances. It is primed to believe totalitarian things.
6. The Left got there first. Left-wing radicals have marched through institutions and imposed illiberal, race-based leftist policies. You cannot understand the rise of the Groypers without understanding this first.
7. Conservatives hoped Trump’s anti-woke pushback would restore the meritocratic status quo. The Zoomercons don’t want that. They want revenge.
8. This has the potential to destroy conservatism politically.
9. It poses the risk of wrecking the new, post-MAGA conservatism, whose natural heir is JD Vance.
10. Anti-Semitism is spreading like a virus among religious conservatives of the Zoomer generation. They’re getting it through online influencers. Their pastors and parents are not fighting back; they have lost authority. Some Zoomer trad Catholics are making antisemitism part of their spirituality — this, despite the fact that the Catholic Church explicitly condemns it. The same phenomenon exists among Zoomercon Orthodox and Protestants. This is spiritual poison.
11. The liberal media is going to have a field day with this to distract from the fact that antisemitism is triumphant among progressives. The new face of the Democratic Party is Zohran Mamdani.
12. Conservatives — Jewish, Christian, and agnostic — who support Israel are going to have to think very hard about how to proceed. Support for Israel has collapsed among the young, and it’s not coming back anytime soon.
13. The intra-conservative fight is here, and we can’t avoid it.
What I Saw And Heard In Washington
Burnout or viso mystica? A Substack article.
Our frenetic and hyperkinetic way of life makes it difficult to take religion seriously and what is essential to it, namely, the belief in what William James calls an Unseen Order. Our communications technology in particular is binding us ever tighter within the human horizon so that the sense of Transcendence is becoming weaker and weaker. It therefore comes as no surprise that someone would point to ‘burnout’ as the explanation of Aquinas’ failure to finish his sum of theology when the traditional explanation was that he was vouchsafed mystical insight into the Unseen Order:
On occasion we encounter morally good people who are sincerely interested in our spiritual welfare, so much so that they fear that we will be lost if we differ from the views they cherish, even if our views are not so very different from theirs. Julian Green in his Diary 1928-1957, entry of 10 April 1929, p. 6, said to André Gide:
With the best will in the world, they never see you without a lurking idea of proselytism. They are worried about our salvation. They visibly have it on their minds., even when you talk to them of quite different matters. . . . “Yes indeed!” cries Gide. “They will use every means to draw you to them. When you are with them you find yourself in the situation of a woman faced with a man who would harbor intentions!”
I’d guess the alacrity and enthusiasm of Gide’s response to Green had its origin in Gide’s relation to Paul Claudel, a committed Roman Catholic who never ceased trying to bring Gide around to the true faith. The Claudel-Gide correspondence 1899-1926 makes for fascinating reading.
What I find objectionable about the proselytic mentality is the cocksurety with which the proselytes hold their views. They dogmatically affirm this and they dogmatically deny that, and are not in the least troubled by the fact that people as intellectually and morally virtuous as they are disagree. They ‘know’ what salvation is and the way to it. The critical attitude is foreign to them. The fervor of their beliefs boils over into something they wrongly consider knowledge.
Their attitude is mostly harmless, but there are toxic forms of it, as history has taught us. The Founders of our great republic were well aware of the religious wars and of the blood shed by the dogmatists. These days it is the spikes of the Islamic trident that are a clear and present threat: conversion, dhimmitude, the sword. The ascension of a madman to the mayoralty in our greatest city is a troubling sign.
Could Frege’s sense-reference distinction be put to work? I think not.
Top o’ the Stack.
I made the point a while back that the vocabularies of phenomenology and neuroscience are radically disparate, such that nonsense arises when one says things like, ‘This burnt garlic smell is identical to a brain state of mine.’ To which a Vietnam veteran, altering the example, replied by e-mail:
. . . when a neuroscientist says your smelling this odor as napalm is nothing but a complex neural event activating several regions of the brain…, he isn’t claiming you can replace your talk about smells with talk about neural signals from the olfactory bulb. Different ways of talking have evolved for different purposes. But he is saying that beneath these different ways of talking & thinking there is just one underlying reality, namely, neural events in our brain.
The idea, then, that is that are are different ways of referring to the same underlying reality. And so if we deploy a simple distinction between sense and reference we can uphold the materialist/physicalist reduction of qualia to brain states. Well, I doubt it. In fact, I deny it.
. . . given the immateriality of the intellect, which I will not attempt to prove now, but let us just assume for the sake of the argument, the activity of the intellect cannot have as its subject the composite of body and soul, or as Aquinas would put it, this activity does not communicate with matter. What this means is that its acts are not acts of any parts of the body, in the way in which, say, my acts of sight are obviously the acts of my visual apparatus enformed [informed] by my sensitive soul.
But the same sensitive soul also has intellective acts, which Aquinas argues cannot be the acts of any bodily organ, or to put it simply, I am not thinking with my brain (or any other organ for that matter): my brain merely provides, so to speak, “food for my thought”, in the form of phantasms, the singular representations of sensible singulars, which then my intellect further processes in its own acts of abstraction, concept formation, judgment formation and reasoning, all of which are acts of the intellect alone, which therefore cannot have the body and soul composite as their subject, but the soul alone.
We are told that the soul-body composite cannot be the subject of sensory knowledge any more than it can be the subject of intellective knowledge. This, however, has the consequence that the intellective soul is not only a form, enforming [informing] the body, but is also a subject of its own power, the intellect, and its acts. But then, it exists not only as that by which the living body is, but also as that which is the underlying subject of its own acts which it does not communicate with the body. Therefore, upon the death of a human person, when the soul gets separated from the body, the soul ceases to be the form of the body, but that does not mean that it also has to cease to be. Since its own operations are not acts of the body, they can continue without its union with the body. But to operate, it must exist; so, it can naturally go on existing, as the underlying subject of its own intellectual operations. So, when a person dies, the person ceases to exist, but the person’s soul merely ceases to be a form of their body, which can persist in its being, naturally continuing the life that used to be the life of the person, as a separate soul, until the same person will be miraculously restituted in the resurrection, resuming the same life, now as a whole person again.

This entry continues the line of thought in Is Classical Theism a Type of Idealism?
God freely creates beings that are both (i) wholly dependent on God’s creative activity at every moment for their existence, and yet (ii) beings in their own own right, not merely intentional objects of the divine mind. The extreme case of this is God’s free creation of finite minds, finite subjects, finite unities of consciousness and self-consciousness, finite centers of inviolable inwardness, finite free agents, finite yet autonomous free agents with the power to refuse their own good, their own happiness, and to defy the nature of reality. God creates potential rebels. He creates Nietzsche, Sartre, and Camus. He creates Lucifer the light bearer who, blinded by his own light, refuses to acknowledge the source of his light, and would be that source himself even though the project of becoming the source of his own light is doomed to failure, and he knows it, but pursues it anyway. He creates Lucifer who became the father of all perversity. The “Father of lights” (James 1:17) creates the father of lies.
God creates and sustains, moment by moment, other minds, like unto his own, made in his image, who are yet radically other in their inwardness and freedom. He creates subjects who exist in their own right and not merely as objects of divine thought. How is this conceivable?

I found a passage in De Ente et Essentia that is relevant to my claim that Thomas is not a hylomorphist with respect to the human soul but a substance-dualist. Here is the passage in the Armand Maurer translation. The numbers in brackets are my interpolation. My commentary follows.
[1] This is why among these substances [created intellectual substances] we do not find a multitude of individuals in the same species . . . except in the case of the human soul because of the body to which it is united. [2] And even though the individuation of the soul depends on the body as for the occasion of its beginning, because it acquires its individuated being only in the body of which it is the actuality, it is not necessary that the individuation cease when the body is removed. [3] Because the soul has a separate being, once the soul has acquired its individuated being by having been made the form of a particular body, that being always remains individuated. [4] That is why Avicenna says that the individuation and multiplication of souls depends on the body as regards its beginning but not as regards its end. (On Being and Essence, 2nd rev. ed, 1968, The Pontifical Institute of Medieval Studies, pp. 62-63.)
Commentary
Ad [1]. Created intellectual substances are either angels or human souls. Angels, of which there are many, are wholly immaterial. They are nonetheless composite beings in that they do not exist in virtue of their essence (quiddity) but receive their existence from God. Since there is no matter-form (hylomorphic) composition in them, what makes them many cannot be matter. And so each is a species unto itself. Their numerical difference is a difference in species.
Human beings, by contrast, all belong to the same species where the genus is animal, the species is human, and the specific difference is rationality. “Man is a rational animal.” The numerical difference of human beings among themselves is therefore not a difference grounded in a difference of species but a difference grounded in a difference in designated matter (materia signata).
Ad [2]. We are then told that a human soul first begins to exist when it acquires a body. Human souls do not pre-exist their embodiment. This is because the human soul is individuated — made to be an individual soul — by its acquisition of a body. Before Socrates acquired a body, there was no individual Socrates. Socrates cannot exist in reality except as an individual human being and he cannot exist as an individual human being without a material body. It is embodiment that brings about his individuation. So far, so good.
Now comes the crucial inference: because the human soul acquires its individuated being (existence) in the material body of which the soul is the actuality, it is not necessary that the individuation cease when the body is removed. Why not?
Ad [3]. The reason is because the soul’s individuation brings it about that the soul is a separate being. Unfortunately, Aquinas appears to be equivocating on ‘separate.’ No doubt the individuation of the soul of Socrates bring it about that his soul is separate from Plato’s soul in the sense of numerically different from Plato’s soul. But that is not to say that the soul of either is separate in the sense of existing without a body either before or after death.
I now explain the two senses of ‘separate.’
The cat is on the mat. The cat is separate from the mat, and the mat from the cat. That is equivalent to saying that cat and mat are numerically different. But neither is separate from designated matter. So ‘separate’ has these two different senses. Separation in the first sense is a symmetrical dyadic relation. It is existence-entailing on both ends: if x is separate from y, then x, y both exist. Separation in the second sense is not a relation at all. A separate substance such as an angel is not separated from anything. There is no parcel of designated matter that the angel Gabriel has to be separate from to be a separate substance.
So it looks as if Thomas is equivocating on ‘separate.’ One hesitates to tax such a great thinker with the fallacy of equivocation. But even if Thomas is not equivocating on ‘separate,’ his argument remains puzzling. Angels are separate substances: although not self-subsistent like God, they subsist without matter. They are individual in themselves, as forms. They need no individuation ab extra. They are already, logically speaking, individuals. Socrates does need individuation ab extra, and it comes from matter. Before he began to exist, he was nothing in reality: he was not a subsistent individual form that acquired a body. He became an individual only when a certain soul-body/ form-matter composite came to be. How then can the soul or form of that composite continue to exist when the composite is no more? This is impossible on Aristotelian hylomorphism, according to which the ‘principles’ of a hylomorphic compound substance are not themselves substances but non-independent ontological ‘parts’ or constituents of the substance of which they are the constituents.
Is Aquinas telling us that when Socrates died he became an angel? I reckon not. (That would be quite the metabasis eis allo genos!) Not even the doctor angelicus became an angel at death. He is however telling us that when the philosopher died he became a separate intellectual substance, and thus like an angel in that respect. Bear in mind that for Thomas, an incomplete substance is a substance. An incomplete substance is logically capable of independent existence: it is not an accident of a substance nor a ‘principle’ of a substance.
So, while Socrates post-mortem is no angel, sensu stricto, he is a separate intellectual substance, a substance that exists in reality on its own without matter. How exactly, given that for humans, as opposed to angels, (designated) matter is the principium individuationis?
The Aquinate line seems to be that the individuation that human souls acquire from matter before death remains with those souls after death. But what is the argument for this surprising thesis? The only argument I discern in the above text is this:
a) Designated matter individuates human souls;
b) Such individuation by designated matter makes of the soul a separate substance;
c) A separate substance does not depend on matter for its subsistence; ergo,
d) A human soul once individuated is forever after a separate substance.
But what reason do we have to accept (b)? No reason at all on a strictly hylomorphic approach. In fact, such an approach rules out (b). The form or soul of a living substance such as Socrates is merely a ‘principle’ of this compound sublunary substance — as I have stated many times already. These principles are not themselves substances. So they cannot exist on their own. Hence they cannot exist without matter. On strict hylomorphism, the soul of Socrates cannot continue to exist upon the dissolution of his body.
Everything falls into place, however, once you see that Aquinas is not a hylomorphic monist, but a substance-dualist. He simply presupposes the truth of (b). This presupposition is logical ‘fallout’ from Christianity as he understands it.
Edward Feser writes,
Hey Bill, many thanks for your Substack post on Immortal Souls. I’ve written up a reply As you’ll see, at the end I give a shout out to your book Life’s Path: Some Trail Notes which I have enjoyed and profited from. You are the rare contemporary philosopher who has both technical chops and the virtue of wisdom in the broad sense that includes understanding of concrete human life. It’s amazing and depressing how many academics are utterly devoid of the latter.
Thanks for the kind words, Ed. Now on to your criticisms.
You say that on the A-T theory, “while each individual physical substance has its own substantial form, with physical substances of the same species their substantial forms are of the same kind.” You suggest that this is something I haven’t understood, but I don’t disagree with you. Your point is that each physical substance has its own substantial form. That’s right; we all understand that Aristotelian forms are not Platonic Forms. Unlike Platonic Forms, which enjoy a transcendent existence in a topos ouranios whether or not they are instantiated here below, Aristotelian forms can exist only in concrete particulars. Platonic Forms are transcendent, Aristotelian forms immanent. As I see it, Platonic Forms are transcendent in two senses: (i) they exist whether or not any concrete particulars participate in them; (ii) they do not enter into concrete particulars as constituents of them. Aristotelian (substantial) forms, by contrast, are not transcendent but immanent, and in a two fold-sense: (iii) they cannot exist on their own but only in concrete particulars; (iv) they exist in concrete particulars as their constituents. Thus Platonic participation (methexis, μέθεξις) is very different from the relation that obtains between a complete Aristotelian primary substance and its ontological constituents or ‘principles’ which are not themselves substances. Plato and Aristotle thus offer two very different theoretical explications of the pre-analytic or pre-theoretical notion of instantiation.
As you say, and I agree, an Aristotelian substantial form “is a concrete principle intrinsic to a substance that grounds its characteristic properties and powers.” You also say, and I agree, that on the A-T theory, “the soul is a substantial form of the kind that gives a physical substance the distinctive properties and powers of a living thing.” It follows from these two points that each living physical substance has its own soul or psyche, where the soul of a living thing is its life-principle. This holds for both human animals such as Socrates and Plato and for non-human animals. We also agree that humans, unlike other living things, have both corporeal and noncorporeal properties and powers. So far, I believe we are ‘on the same page’ at least with respect to what the A-T theory says. I take it we agree on the content of the theory; our dispute concerns its coherence.
But let’s dig a little deeper. It seems to me that the A-T conception further implies that matter (materia signata) plays a dual role: it both individuates and differentiates. These are different ‘ontological jobs’ even though on the A-T scheme signate matter does both of them. Two questions.
(Q1) Why do Socrates and Plato each have their own individual substantial forms and thus — given that souls are substantial forms — their own individual souls? Answer: because forms, which cannot exist Platonically, but only in concrete particulars, are individuated or particularized by the parcels of matter which they inform or in which they inhere.
(Q2) Why do Socrates and Plato differ numerically? Why are they two and not one? Because each is a numerically different hunk of matter. So matter (designated matter) is the ground both of the individuation of forms — that which makes them individuals and not universals — and that which grounds the numerical difference of the two complete physical substances.
So much for the pre-mortem situation of Socrates and Plato. With respect to the pre-mortem situation, Aristotle and Thomas pretty much agree about human beings (rational animals). Post-mortem, however, important differences surface due to Thomas’s Christian commitments which, needless to say, are not shared by Aristotle. And so we need to ask how well these Christian commitments comport with the Aristotelian scheme.
For Thomas, human souls after death are (1) subsistent, (2) separable, (3) multiple, (4) incomplete, (5) personal, and (6) such that the soul no longer functions as a life-principle but only as a ‘seat’ of noncorporeal intellectual operations. I’ll explain these points seriatim.
Ad (1). The souls of rational animals, unlike the souls of nonrational animals, continue to exist after death.
Ad (2). The souls of rational animals can and do exist after death in a disembodied state, i.e., apart from matter. So they don’t merely subsist; they subsist in an immaterial way.
Ad (3). Just as there are many human beings ‘on earth,’ i.e., in the physical realm, there are many disembodied human souls after death. Whatever the number is, it is neither one nor zero. Moreover, for each human being that existed ‘on earth,’ there is exactly one soul after death (whether in heaven, hell, purgatory, or limbo) and this soul after death is numerically identical to the soul of the human before death. Thus the soul of Socrates after death is numerically the same as the soul he had before death.
Ad (4). Human souls after death, but before resurrection, are substances all right, but incomplete substances in that they lack a body when it is their nature to exist in an embodied state.
Ad (5). Human souls after death are persons in that they are conscious and self-conscious, albeit in non-sensory ways. In Summa Contra Gentiles, Book IV, chs. 92-95, Aquinas elaborates on the will’s fixity after death: “souls immediately after their separation from the body become unchangeable in will with the result that the will of [a] man cannot further be changed, neither from good to evil, nor from evil to good.” (Ch. 92, top.) Suppose you go straight to heaven after death. Your will will be eternally fixed upon the good. This fixity of will is a modality of consciousness and also of self-consciousness inasmuch as the soul will be aware of its fixity of will. That is, the soul is aware that it wills, and what it wills. What’s more, the souls in heaven presumably can ‘hear’ petitionary prayers from souls ‘on earth’ and ask God to grant those petitions. This non-sensory ‘hearing’ is a modality of consciousness. The souls in heaven are aware of the petitions and formulate the intention to intercede with God for the benefit of the earthly petitioners.
Ad (6). Dead humans are no longer alive. So the soul of a human after death and before resurrection does not function as a life-principle. It can so function only if it is joined to an animal body that it enlivens or animates. But the soul of a human after death does function as the subject of conscious states such as the volitional state of willing only the good. The soul of a human before death, however, functions in both ways, as an animating principle, and as that in a human which is aware when it is aware of this or that. The difference is between the soul as life-principle and the soul as subject or ego or I.
I hope I have made clear that I really do understand what the A-T theory maintains. My disagreements with Ed Feser are not about the content of the theory, but about its coherence and thus its tenability.
The point I was making in the Substack piece could be put like this. After the death of a mortal man such as Socrates, and the dissolution of his material body, the soul he had can no longer be his soul. The reason for this is that the individuating or particularizing factor, signate matter, which made the soul he had his soul, is no longer present after death. To appreciate this point you must not forget that the form of a (primary) substance is not itself a (primary) substance, but a ‘principle’ — Ed uses this very word — or constituent of a substance which together with the material constituent constitutes a (primary) substance. Thus the constituents or ‘principles’ of a substance are not themselves substances and therefore not themselves metaphysically capable of independent existence. Bear in mind that for Aristotle, primary substances are basic entities in the sense that they do not depend on anything else for their existence in the way a smile depends on face. But what I have just argued — that the soul of Socrates after death cannot be his own soul — contradicts (3) which is a non-negotiable doctrinal commitment of Thomism. The lesson to be learned from this is that Aristotelian hylomorphism is not consistent with the characteristic commitments of Thomism. Note that I am not denying the doctrinal commitments listed above. My point is that they cannot be rendered intelligible by the use of Aristotelian conceptuality, in particular, hylomorphism.
My point can also be made from the side of differentiation. Thomas is committed to saying that Socrates and Plato are as soulically or psychically distinct in the afterlife as they are in this life. But in the afterlife before resurrection they lack material bodies. Lacking bodies, they lack that which could ground their numerical difference. So if the two men after death are two numerically different souls, then souls are not mere Aristotelian forms. They are substances in their own right. This is why Richard Swinburne, no slouch of a philosopher, speaks plausibly and indeed correctly of “Thomist substance dualism.” (Are We Bodies or Souls? Oxford UP, 2019, p. 82)
Aristotle is not a substance dualist, but Thomas is. This is not to say that Thomas is a substance dualist in the very same sense that Descartes is. But he is a substance dualist nonetheless.
I expect Ed to balk at this and reiterate the bit about ‘incomplete’ substances formulated above in point (4). Let’s think this through as sympathetically as possible. If a life-principle is actually functioning as such, then there must be a physical body it enlivens or animates. It therefore makes perfect sense for Thomas to say to say that it is the nature of a life-principle to be joined to a body. For a life-principle to be a life-principle of a material thing, there must be a material thing whose life-principle it is. So if human souls are life-principles, then it is the nature of the human soul to have a body. But post-mortem souls before resurrection are not functioning as life-principles. And yet Thomas insists that after death and before resurrection human souls continue to exist and are numerically the same as the souls that existed before death. One survives one’s bodily death as a person, as a self, as a subject of conscious states. So is it not obvious that human souls before death and after death (but before the re-embodiment consequent upon resurrection) are not mere substantial forms but substances in their own right? I say it is obvious and it puzzles me that what is obvious to me is not obvious to Ed. Try this syllogistic chain on for size.
I conclude that Aquinas’s conception of the soul is not hylomorphic sensu stricto but substance-dualist. Hylomorphism does not render the angelic doctor’s doctrinal commitments intelligible. And that was my point.
I have heard it said that Thomas is an Aristotelian on earth, but a Platonist in heaven. That is an approximation to the truth, but it just now occurred to me that it is not quite right, and may be more clever than truthful. For Aquinas is committed to the diachronic numerical identity of the person or self both in this life and on into the after life. So even in this life there has to be more to the soul than a life-principle. I conclude that even in this life Thomas is not wholly Aristotelian. If Thomas is a substance-dualist in heaven, he must also be one on earth as well .A follow-up post will make this more clear.
Addendum (10/29). This morning I found a section on Aquinas in John W. Cooper, Body, Soul, and Life Everlasting, Eerdmans 1989, p. 11-13. Cooper makes points that support what I argue above. He states that Thomas “combined important features of the Aristotelian body-soul relation with a basically Augustinian dualistic framework.” Although “Thomas uses Aristotle to emphasize the unity of human nature,” he “remains with Augustine in affirming that the soul is a distinct substance which can survive biological death.” Cooper appreciates that a Christian cannot take an Aristotelian approach to the soul. “For Aristotle’s soul is only the form of the body and not a substance as such. Therefore it cannot survive death as an individual entity.” (13) Thomas abandons Aristotle by holding that “the soul is both the form of the body and an intellectual substance in its own right.”
Swinburne, Cooper, and I are saying the same thing.
