The Most Important Question in the Metaphysics

I wrote the following to a friend. To me it seems perhaps the most important question in the Metaphysics:

It seems that somewhere in the Met, Aristotle should give a justification for the possibility of the existence of non-material substances. If in Lambda he is going to assert that such substances exist, then he needs to give an argument, it seems, that such substances *can* exist. But do you think that anywhere in the central books he is arguing with that end in view--that is, that he is setting down ideas, or considerations, which imply that there is no obstacle to forms existing apart from matter?

I suppose the alternative is simply to hold that when, in Lambda, he argues that something must exist which has no potentiality, then ipso facto he shows that it has no matter. But, still, one wants to know how such a thing could exist, if in every other case, or nearly so, forms exist through matter.
My friend replied that Z seemed to do no more than leave open the possibility of immaterial substances, but that perhaps Q 8 was the place to look for something more definite. My friend also suggested that an 'immaterial susbstance' should perhaps not be understood as a 'form existing without matter.' (But then how should it be understood?)

Do
you have an idea how to answer my question?

Aristotle from K. to Z

I raised the question here whether by 'primary substance' in the Categories Aristotle means simply particular things (as the common wisdom goes), or whether he means something like an instance of a nature. There was a simple and so far unanswered argument for the latter: the categories are highest kinds of existences; thus, substances are distinct existing things from accidents; thus, the primary substance of a thing must be something distinct from any of its accidents; and therefore the substance of a thing is distinct from the thing, which would include its accidents.

In subsequent posts I pointed out that, when a primary substance is thus understood as 'an instance of a nature', then the Categories becomes aligned with the Metaphysics in important ways.

First, it becomes natural to speak of the substance of a thing, since the substance is not the thing. This idiom is not a strange, unaccountable innovation of Z3, but simply what has been presumed all along. (Yes, there remains an everyday sense in which people want to say that things are substances. But the Categories shows that this way of speaking needs justification: once we clarify what the primary substance is, this usage appears imprecise and derivative.)

Second, the 'matter' of a primary substance (the stuff of which it is composed) must be conceived as in some important way 'indeterminate': the primary substance being distinct from definite accidents of quantity, place, and position, any 'stuff'' it may have will be so as well. And yet Aristotle investigates indeterminate matter in the Metaphysics.

Third, we might wonder whether an indeterminate thing could still be a subject, and in what way.

Fourth, since it appears problematic how something indeterminate may still be matter, the Categories view of primary substance invites investigation into to what extent the matter of a thing should enter into its essence or definition.

Fifth, by the same token, to the extent that it appears problematic that matter does enter into the essence and definition of a substance, to that extent it will appear likely that the substance is somehow constituted by universals or kinds.
That is, the entire project of Z comes out of the conception of primary substance as an instance of a nature: the investigation of hypokeimenon; essence; universal; genus.

But I wonder, still, whether there is good textual evidence in the Categories to support the 'unanswered' argument given above. As I said, I think I have found some, and I'll give it in a subsequent post.

Controlled Fission

Here's another passage from the Categories that suggests that Aristotle did not regard primary substances as 'atoms'. Call this Passage A:

We need not be disturbed by any fear that we may be forced to say that the parts of a substance, being in a subject (the whole substance), are not substances. For when we spoke of things in a subject we did not mean things belonging in something as parts. (3a29-32, Ackrill)

mh_ taratte/tw de\ h(ma~j ta_ me/rh tw~n ou)siw~n w(j e0n u(pokeime/noij o1nta toi=j o3loij, mh& pote a)nagkasqw~men ou)k ou)si/aj au)ta_ fa&skein ei]nai: ou) ga_r ou3tw ta_ e0n u(pokeime/nw| e0le/geto ta_ w(j me/rh u(pa&rxonta e1n tini.
This is perplexing, is it not? What does Ackrill say in his commentary, to clear it up? Nothing; he skips right over this passage.

Nor does he refer to it, when he discusses the earlier passage, which we had looked at already, to which this one looks back. I'll quote it again. Call this Passage B:
Some are in a subject but are not said of any subject. (By 'in a subject' I mean what is in something, not as a part, and cannot exist separately from what it is in.) For example, the individual knowledge-of-grammar is in a subject, the soul, but is not said of any subject; and the individual white is in a subject, the body (for all color is in a body), but is not said of any subject. (1a24-27, Ackrill)
About which Ackrill says:
Aristotle's explanation of 'in a subject' at 1a24-25 is slight indeed. One point deserves emphasis. Aristotle does not define 'in X' as meaning 'incapable of existing separately from X', but as meaning 'in X, not as a part of X, and incapable of existing separately from what it is in'. Clearly the 'in' which occurs twice in this definition cannot be the technical 'in' of the definiendum. It must be a non-technical 'in' which one who is not yet familiar with the technical sense can be expected to understand. Presumably Aristotle has in mind the occurrence in ordinary Greek of locutions like 'heat in the water', 'courage in Socrates'.
I think not. Presumably Passage A is relevant at this point, and it indicates that the main non-technical usage of 'in', which Aristotle has in mind, is the way in which a part is in a composite whole.

And, given Passage B, wouldn't it be natural to understand Passage A as telling us that "we needn't be disturbed by any fear that we may be forced to say" that the soul, which is in this individual human (as a part), is not a substance, and that the body, which is in this individual human (as a part), is not a substance? That is: we are not hindered from analyzing this primary substance as compounded of two substances.

And then, finally, as Ackrill points out, observe that Aristotle has crafted Passage B in such a way as to leave open the possibility that the way in which the soul (or body) exists in the individual human is not such as to make it incapable of existing separately.

Splitting the Atom

I wonder if anyone saw the significance in the passage from the Categories which I quoted the other yesterday:

Some are in a subject but are not said of any subject. (By 'in a subject' I mean what is in something, not as a part, and cannot exist separately from what it is in.) For example, the individual knowledge-of-grammar is in a subject, the soul, but is not said of any subject; and the individual white is in a subject, the body (for all color is in a body), but is not said of any subject. (Ackrill)
It's a common view that, in the Categories, Aristotle treats substances as unanalyzable 'atoms'. One finds this claim repeated again and again. S. Marc Cohen's statement, from his SEP article, also quoted already (in part), is representative:
The concepts of matter and form, as we noted, are absent from the Categories. Individual substances — this man or that horse — apart from their accidental characteristics — the qualities, etc., that inhere in them — are viewed in that work as essentially simple, unanalyzable atoms. Although there is metaphysical structure to the fact that, e.g., this horse is white (a certain quality inheres in a certain substance), the fact that this is a horse is a kind of brute fact, devoid of metaphysical structure. This horse is a primary substance, and horse, the species to which it belongs, is a secondary substance. But there is no predicative complex corresponding to the fact that this is a horse in the way that there is such a complex corresponding to the fact that this horse is white.
But this is false, isn't it?

Look again at that passage from the Categories. There we find, at the very beginning of the work--when Aristotle is setting down some fundamental distinctions, between substance and accidents, and between particulars and universals--he gives as examples, not "individual knowledge-of-grammar is in the individual man" or "individual whiteness is in the individual man", but rather "individual knowledge-of-grammar is in the soul", and "individual whiteness is in the body."

That is, from the start, Arisotle is prepared to analyze primary substances, when they are living things at least (and these are agreed to be paradigmatic primary substances, for Aristotle) into body and soul.

Cohen is simply incorrect that "this is a horse is a kind of brute fact, devoid of metaphysical structure." No, 'this is a horse' is analyzed into 'this is a soul and a body'.

Tell a story, if you wish, about how Aristotle's use of the form-matter distinction in analyzing substances is a development of the soul-body distinction. But that Aristotle recognizes the possibility and appropriateness of analysis, from the very start, is undeniable.

My Accomplishment Consists in This, That I Am Aware That I Lack Accomplishment

From what has been said, then, it is clear that intellectual accomplishment is a combination of systematic knowledge and intelligence, with the things that are highest by nature as its objects.
I don't imagine anyone could guess in advance that this sentence was about sophia. It's a translation of Nic. Eth. 6.8 1141b2-3. e0k dh_ tw~n ei0rhme/nwn dh~lon o3ti h( sofi/a e0sti\ kai\ e0pisth&mh kai\ nou~j tw~n timiwta&twn th|~ fu&sei. (And 'highest' is an undertranslation, to be sure.)

And consider this one, the sentence that follows:
That is why people call Anaxagoras and Thales and people of that sort 'accomplished', but not 'wise', when they see them lacking a grasp of what is to their own advantage; and they say that people like that know things that are exceptional, wonderful, difficult, even superhuman--but useless, because what they inquire into are not the goods that are human. It is wisdom that has to do with things human.
This is almost unintelligible and fails dramatically to convey Aristotle's sense-- "Ah, there goes Thales again, falling into a well. That's what happens when you are accomplished but lack any wisdom."

I take both of these sentences from Rowe and Broadie, who render sophia as 'intellectual accomplishment' and phronesis as 'wisdom.' Their treatment of the intellectual virtues, as a result, becomes so confusing that I can hardly recommend their translation, even if in other respects it may be the best available.

Work in Progress

This is something odd I noticed about S. Marc Cohen's entry on "Aristotle's Metaphysics" in SEP.

The entry amounts to about 12 pages on my screen. Of these, 2 pages are introductory. 9 concern book Z. One page deals with material elsewhere in the Metaphysics. There is no discussion of Lambda.

How is this a suitable encyclopaedia entry on this topic? On his homepage Cohen describes the entry as 'a nearly complete draft'. But since when does SEP publish drafts? (I see nothing in the SEP editorial policy acknowledging that it publishes drafts.) And if some of its entries are 'drafts', shouldn't these be identified as such?

True, SEP is a self-described 'dynamic reference source'. But shouldn't that mean that finished drafts will be revised as called for, not that drafts get posted as if they were finished?

A Schizophrenia in Aristotle Scholarship

When people lecture on Aristotle's De Anima, it is common, I think, that they say something like this:

Aristotle takes a hylomorphic view of the relationship between soul and body. That is, he thinks that soul stands to body as form to matter. But forms depend on the matter which they inform: when the bronze is melted, the statue is destroyed at the same time. Thus, Aristotle's hylomorphism places him generally at odds with Plato. Hylomorphism is inherently incompatible with dualism. It is true that Aristotle leaves open the possibility that some souls, or some functions of some souls, exist independently of a body. And possibly he even believes that himself. But, if he does, this looks like a strange and perhaps even unaccountable divergence from what is the basic outlook of his philosophy of mind.
Yet when they lecture on the Metaphysics, they might say something like the following:
The central books of Aristotle's Metaphysics are a careful examination of substance as form. In these books, Aristotle looks largely at 'sensible' substances, that is, substances that have matter. Yet he thinks that Metaphysics in the proper sense is 'first philosophy', which is concerned with, as he puts it, non-sensible and unchangeable substances. His discussion of sensible substances is meant to prepare the way for his examination in book Lambda of separately existing, non-sensible substances. These are pure forms, which exist without matter.
That is, these lecturers ascribe to Aristotle the incompatible view that (i) forms can exist without matter, and that the most important substances are like that (those which, from the point of view of knowledge and explanation, are most basic); yet (ii) forms depend on matter for their existence, and it would be strange and unaccountable to regard some forms as independent of matter.

Chris Shields, in his SEP article, is not so crude as the lecturer I imagine above:
In a fairly direct way, though, the question of whether soul and body are one loses its force when it is allowed that it contains no implications beyond those we establish for any other hylomorphic compound, including houses and other ordinary artifacts.

One way of appreciating this is to consider a second general moral Aristotle derives from hylomorphism. This concerns the question of the separability of the soul from the body, a possibility embraced by substance dualists from the time of Plato onward. Aristotle's hylomorphism commends the following attitude: if we do not think that the Hermes-shape persists after the bronze is melted and recast, we should not think that the soul survives the demise of the body. So, Aristotle claims, “It is not unclear that the soul -- or certain parts of it, if it naturally has parts -- is not separable from the body” (De Anima ii 1, 413a3-5). So, unless we are prepared to treat forms in general as capable of existing without their material bases, we should not be inclined to treat souls as exceptional cases. Hylomorphism, by itself, gives us no reason to treat souls as separable from bodies, even if we think of them as distinct from their material bases. At the same time, Aristotle does not appear to think that his hylomorphism somehow refutes all possible forms of dualism. For he appends to his denial of the soul's separability the observation that some parts of the soul may in the end be separable after all, since they are not the actualities of any part of the body (De Anima ii 1, 413a6-7). Aristotle here prefigures his complex attitude toward mind (nous), a faculty he repeatedly describes as exceptional among capacities of the soul.

Yet even Shields' discussion leaves something to be desired, because he writes as if the independence of mind from body is a special exception to the doctrine of hylomorphism, pressed upon us, perhaps, by attention to human psychology. There is no suggestion in the above paragraph--as there should be--that Aristotle thought that a careful examination of hylomorphism itself would show that forms could in principle exist independently of matter. (The sentence, "At the same time, Aristotle does not appear to think that his hylomorphism somehow refutes all possible forms of dualism", is misleading through understatement.)

Souls Are Particulars

Chris Shields considers this neat argument, in his SEP article on Aristotle's psychology, that, according to Aristotle, particular forms exist:

  1. All souls are forms.
  2. Some souls are particulars.
  3. Thus, some forms are particulars.
(It could be that all souls are particulars. The weaker claims suffice.)

Since 1. is so entrenched in Aristotelian psychology, the only plausible way to deny the conclusion is to deny that Aristotle accepts 2. Shields admits that in this controversy it is difficult to find a 'proof text'. Yet he does not consider Categories 1a25.

It is conceded on all sides that the Categories distinction between 'said of'/'not said of' is meant by Aristotle to be a distinction between universals and particulars: 'This particular instance of grammar', since it is an individual, is not 'said of'' someone, although 'grammatical', a universal, is. ('Socrates is grammatical' makes sense; 'Socrates is an instance of grammatical knowledge' does not.)

Presumably, too, a particular which exists in something, exists only in a particular.

Thus, when Aristotle gives as an example:
Some are in a subject but are not said of any subject. (By 'in a subject' I mean what is in something, not as a part, and cannot exist separately from what it is in.) For example, the individual knowledge-of-grammar is in a subject, the soul, but is not said of any subject; and the individual white is in a subject, the body (for all color is in a body), but is not said of any subject. (Ackrill)

This shows that he regards some souls as particulars, in just the same way that he regards bodies as particulars. (One may resist the conclusion by invoking developmentalism, but it is not clear that that recourse would escape the charge of circularity.)

Sorted Details

I'm following three threads, now: (i) the status of primary substances in the Categories; (ii) the nature of the investigation in Met. Z; and (iii) how Met. Z contributes to the 'first philosophy' of Lambda. Here is something on that second thread.

Recall that I took a hint from Aquinas in De Ente et Essentia and began to think of Z as asking not, as is commonly supposed, 'What is substance?', but rather, 'What makes something such that it can be sorted?'--it being presumed that substance does that. I said that, according to Aquinas, Aristotle regarded this investigation as suggested by the doctrine of the categories. I gave Aquinas' argument for this, based on the fact of the categories, and I gave an alternative argument, based on the priority of substance among the categories. I said that I saw no evidence that Aquinas' argument was in Z1, but that I did see evidence that the other argument was in Z1.

I want to take that back. I now believe that both arguments are put forward at the opening of Z1. To see that they are requires that we parse the opening of the chapter appropriately. Here is the relevant passage, parsed as I think it should be:

(A) There are several senses in which a thing may be said to 'be', as we pointed out previously in our book on the various senses of words;' for in one sense the 'being' meant is 'what a thing is' or a 'this', and in another sense it means a quality or quantity or one of the other things that are predicated as these are.
(B) While 'being' has all these senses, obviously that which 'is' primarily is the 'what', which indicates the substance of the thing.

(i) For when we say of what quality a thing is, we say that it is good or bad, not that it is three cubits long or that it is a man; but when we say what it is, we do not say 'white' or 'hot' or 'three cubits long', but 'a man' or 'a 'god'.
(ii) And all other things are said to be because they are, some of them, quantities of that which is in this primary sense, others qualities of it, others affections of it, and others some other determination of it. (And so one might even raise the question whether the words 'to walk', 'to be healthy', 'to sit' imply that each of these things is existent, and similarly in any other case of this sort; for none of them is either self-subsistent or capable of being separated from substance, but rather, if anything, it is that which walks or sits or is healthy that is an existent thing. Now these are seen to be more real because there is something definite which underlies them (i.e. the substance or individual), which is implied in such a predicate; for we never use the word 'good' or 'sitting' without implying this. Clearly then it is in virtue of this category that each of the others also is. Therefore that which is primarily, i.e. not in a qualified sense but without qualification, must be substance.)
I take (i) and (ii) to provide reasons for the inference from (A) and (B).

But--and this is crucial--I understand (B) to be, not the assertion of the priority of substance (which has been said many times earlier in the treatise), but rather the added idea that this category which is prior indicates 'what' a thing is and that this is called 'substance'. That is, substance is that which makes something such that it is identifiable as a 'what' and can be sorted.

Argument (i) in support of this does seem to be Aquinas' argument. Commentators puzzle over why Aristotle starts talking about the category of quantity here. "Aristotle's object being to distinguish quality from substance, not from the other categories," Ross comments, "'three cubits long' is irrelevant and was suspected by Bonitz. It was, however, read by Alexander, and apparently by Asclepius, and Aristotle is not incapable of such irrelevancies..." Better, I should think, to conclude that Ross is not correct about Aristotle's object. Suppose his object is to make a point about sorting. Suppose he wants to make the subtle and complex observation that, to say anything at all (white, three cubits) presupposes a fundamental act of sorting, viz. into one of the categories; and yet it's not as if all of the categories are on a par, since that which we explicitly recognize as telling us 'what' a thing is gets priority. (Odd, because all the categories tell us what a thing is.)--This, then, would be an argument like that which Aquinas puts forward.--And in this connection the mention of a quantity would hardly be an 'irrelevancy'.

Argument (ii) is the argument that I proposed.

Note, by the way, that if by 'substance' we mean that which makes something such that it can be sorted, then 'substance' would have to indicate some part or aspect of a thing (and so we would want to talk about the substance of a thing) because, clearly, we do not count everything about an individual as relevant to sorting it.

Getting to the Substance of Things

"Thanks for the question, especially because it made me consider something I hadn't thought about distinctly. Wouldn't it have to be that primary substances are 'theoretical substances'? Though it's difficult to conceive of a 'this man' without his accidents, if a first substance were to include the accidents, then wouldn't an accidental change, by that conception, actually be a substantial change? I mean, if a primary substance includes the accidents, then a change in the accidents would make the 'this man' now a different 'this man'. For example, if Socrates as a primary substance includes the color of his hair, then wouldn't dying his hair make him a new instance of man?"
In my informal polling, that's a typical response. I find that people have not thought clearly about this; yet, when the distinction I raised is posed to them, then they are compelled to say that a primary substance in the Categories is 'an instance of a nature' (as I put it), not a commonsense 'thing'.

What's interesting about an 'instance of a nature', is that, as the quotation above notes, it would lack definite determination of its matter. An instance of human nature would surely be an instance of a soul-with-body, and yet the body would have to be conceived--somehow--as not having a definite size. One would be tempted to say that an 'instance of human nature' was somehow simply a form, that it did not involve matter (on the grounds that matter had to be definite).

Far from this being an objection, I find this difficulty promising as regards interpretation, because it shows that a consideration of the relation of form to matter in primary substances would follow naturally, and almost inevitably, from the very conception of a primary substance understood as an 'instance of a nature'. Think of a primary substance as human nature without accidents, and then inevitably one wants to know how this human nature could involve matter (the body) if at all.

I think it's possible to show that various passages in the Categories require that primary substances be 'theoretical substances'. I'll try to post more on this.

Can Atomists Be Happy?

The following occurred to me when teaching Nic. Eth. 10.7-8 today, in connection with my previous post on Aristotelian monotheism.

Prove: An atomist cannot be happy.

Proof:

  1. Happiness is activity in accordance with the virtue of sophia (1177a12).
  2. Thus, no one who lacks sophia can be happy.
  3. Sophia is knowledge of first causes (1141a19-20).
  4. No one who has false beliefs, and lacks true beliefs, in that respect has knowledge (1139b20-21).
  5. Thus, no one who has false beliefs, and lacks true beliefs, about first causes, has knowledge of first causes.
  6. Atomists have false beliefs, and lack true beliefs, about first causes.
  7. Thus, no atomist has sophia.
  8. Thus, no atomist can be happy.
q.e.d.


Comments

'Atomist' of course stands proxy for that class of people who, on Aristotle's terms, lack knowledge of first causes.

We might grant that there are some philosophers who lacked sophia, but who nonetheless approached happiness in some way, because their beliefs were insightful approximations to the truth (e.g. Plato on the Good, Anaxagoras on Mind).

What the above argument does, is to raise a question about the importance of truth for happiness. Does happiness require that we attain to truth about the most fundamental things? Aristotle's remarks in the opening of the Metaphysics, and his definition of sophia as knowledge, would suggest that it does. If 'all men by nature desire to know', then those who fail, fundamentally, to know, will have failed to attain a 'natural good'--and 'a happy person has all the natural goods' (NE 1169b19).

The argument also takes seriously the fact that happiness is objective, not subjective, for Aristotle. A person can think he is happy, and not be so (see Kraut, "Two Conceptions of Happiness"). Similarly, a person who thinks he has wisdom, but does not, may think he is happy, but is not. (And note the Socratic resonances in this.)

An Aristotelian Shema

I want to answer my question from the previous post: What argument, if any, in the first philosophy of Lambda, seems intended by Aristotle to draw upon results or material from Z?

There is only one such argument, I believe:

Evidently there is but one heaven. For if there are many heavens as there are many men, the moving principles, of which each heaven will have one, will be one in form but in number many. But all things that are many in number have matter; for one and the same definition, e.g. that of man, applies to many things, while Socrates is one. But the primary essence has not matter; for it is complete reality. So the unmovable first mover is one both in definition and in number; so too, therefore, is that which is moved always and continuously; therefore there is one heaven alone. (1074a31-36)

o3ti de\ ei[j ou)rano&j, fanero&n. ei0 ga_r plei/ouj ou)ranoi\ w3sper a1nqrwpoi, e1stai ei1dei mi/a h( peri\ e3kaston a)rxh&, a)riqmw|~ de/ ge pollai/. a)ll' o3sa a)riqmw|~ polla&, u3lhn e1xei (ei[j ga_r lo&goj kai\ o( au)to_j pollw~nm oi[on a)nqrw&pou, Swkra&thj de\ ei[j): to_ de\ ti/ h}n ei]nai ou)k e1xei u3lhn to_ prw~ton: e0ntele/xeia ga&r. e4n a1ra kai\ lo&gw| kai\ a)riqmw|~ to_ prw~ton kinou~n a)ki/nhton o1n: kai\ to_ kinou&menon a1ra a)ei\ kai\ sunexw~j: ei[j a1ra ou)rano_j mo&noj.
This makes use of the notions familiar from Z of to ti en einai, eidos, and hule; and it makes use, too, of a principle from Z, that matter individuates form. And it is the only such passage.

Now, I can't decide whether this is a significant argument or not:
It is insignificant. Aristotle mentions it in passing. It seems a digression. It looks like an ancillary argument, against those who have claimed that there are 'many worlds'.

It is significant. Although the argument is put forward almost in passing, what is important about it, is the principle on which it depends, and which Aristotle affirms, (using results from Z), namely, that the 'first essence' or 'unmoved mover' --God-- is one.
It seems an odd suggestion, and yet there it is: Could it be that the main purpose and point, in Aristotle's eyes, of all of the build-up to first philosophy, in Z and in the other central books of the Metaphysics, is the simple assertion of monotheism? And then the 'wisdom' of first philosophy becomes: the intellectual recognition of a single, supreme first cause.

On this interpretation, the Metaphysics is, as it were, Aristotle's treatise-length and philosophical equivalent of the shema.

A strange idea, I agree, but I do like it better than the 'philosophical fizzle' interpretation.

26 April 2006

A Philosophical Fizzle

I pointed out in an earlier post that the attention that Aristotle gives to perceptible substances in the central books of the Metaphysics, and in Lambda 1-5, raises a difficulty: How does this investigation differ from physics?--since, for Aristotle, physics is distinguished from purely formal disciplines on account of its considering matter together with form. Burnyeat's answer was that Aristotle was 'doing second philosophy conceived as first philosophy', yet it was unclear what this might be.

Here I wish to draw attention to an additional difficulty that arises even if we grant that it makes sense to say that, in those texts, Aristotle is 'doing second philosophy conceived as first philosophy.'

The difficulty is that there still must be some way in which 'second philosophy conceived as first philosophy' is useful for first philosophy proper. After all, why doesn't Aristotle simply launch into a discussion, from the start, of the existence and number of imperceptible substances? Why exactly do we need any preparation for this? Aristotle's own answer is that it helps for us to begin first with things 'more knowable to us', before we move on to a discussion of things 'more knowable in themselves', and (he says) perceptible substances, which have matter, are more knowable to us. Good--but what precisely is the help that we get from them? What are the big lessons, ideas, or principles that we take away from this study and then use when we are doing first philosophy proper?

Let me put the question more concretely: Can you point to a single argument in Lambda, and some argument in Z, such that, in your view, Aristotle regards that argument in Lambda as receiving confirmation or support, which derives from that argument in Z? Or, again: What in Lambda is such that, as Aristotle sees it, a reasonable person should be more disposed to accept it, precisely because of something previously examined in Z? (Or say, if you wish, "because of something like what is examined in Z", to allow for a sometime independent composition of the treatises.)

Burnyeat's Map, despite its consideration of "The place of Z in Aristotle's Metaphysics" (ch. 6), gives almost no insight to this question. The following seems the only relevant remark:

H reworked the concepts of matter and form in terms of potentiality and actuality, these being the concepts we need to make the transition to the non-sensible realm where neither matter nor form apply. Q then undertakes a careful analysis of potentiality and actuality as such. (121)
That is, according to Burnyeat, the entire 'yield' of the central books of the Metaphysics, for the purposes of first philosophy, is the analysis of potentiality and actuality carried out in Q. (One would think that, on the terms of his interpretation, it would be an important result, somewhere, in the central books, that form need not depend on matter for its existence. But I do not see that Burnyeat emphasizes this.) Presumably, then, the consideration of form and matter in Z is 'second philosophy conceived as first philosophy' only to the extent that it prepares the way for the discussion of potentiality and actuality in Q.

We may waive the difficulty of how a 'reworking of the concepts' of A and B could be of any use in an investigation of 'a realm in which neither A nor B apply'.

A more relevant difficulty is that it is not at all clear how Z prepares the way for or is necessary for a consideration of actuality and potentiality. Moreover, if Burnyeat's view were correct, wouldn't that be a disappointing and unsatisfactory result? All of the dialectic in Z, all of its careful analysis and subtle distinctions--this would be of no more philosophical consequence, for Aristotle's project, than to prepare the way (somehow) for a discussion of actuality and potentiality, which, gets used in some of the arguments of first philosophy proper?

That looks like a lot of build-up for a very disproportionate payback. A philosophical fizzle, really.

An Argument for Theoretical Primary Substances

Is there a way to determine whether, in the Categories, Aristotle by 'primary substance' means what I called a 'commonsensical' or a 'theoretical' substance? It would be desirable to establish the latter, I think, since this then brings the Categories into greater harmony with the Metaphysics. In the former work, too, Aristotle would be concerned with 'the substance of a thing', and he would be conceiving of it as that which places that thing in a system of genus-species classification.

It proves difficult to find arguments based on language alone. One consideration is that proper names do not figure in Cat 5, whereas they are used freely in the postpraedicamenta when they are needed to make a point-- which gives some support to the suggestion that primary substances are not what are indicated by proper names.

Here is an argument based on the reduplicative idiom qua.

"Socrates qua quality" asks us to consider some quality of Socrates, say, that he is pale, and thus we may say "Socrates qua quality is pale." In such a sentence, the word 'pale' predicates paleness of Socrates, and in the context the expression "Socrates qua quality" picks out, not Socrates, but this quality which Socrates has.

Similarly, if we say, "Socrates qua quantity is five feet tall", then "five feet tall" predicates five feet of Socrates and "Socrates qua quantity" picks out, not Socrates, but this quantity that Socrates has.

By parity, then, if we say "Socrates qua substance is a man", then "a man" predicates humanity of Socrates, and "Socrates qua substance" picks out, not Socrates, but this substance that Socrates has.

This substance that Socrates has would not be a secondary substance (note that we do not wish to say that "Socrates is man", but rather "a man", indicating an 'atom' or instance of humanity).

The point is that the reduplicative idiom has a use as regards the category of substance, just as it does for the other categories, and then what it picks out is not the individual, Socrates, nor the species or genus, but rather some instance of a nature. The claim would be what this picks out would go undesignated, and something else would be given two designations, unless 'primary substance' indicated this.

Two Arguments from the Categories

Yesterday I considered the suggestion that the key question of Metaphysics Z is not, as is commonly held, "What is substance (ousia)?" but rather "What makes something such that it can be sorted?" --it being supposed that ousia does this.

I took this suggestion from Aquinas' De Ente et Essentia, approaching that work as a brief commentary on Z and Lambda. One advantage of this interpretation, I pointed out, is that it seems to make good sense of the topics actually considered in Z.

Yesterday I also noted that Aquinas thinks that Aristotle arrives at this question through a consideration of the categories. Now there would seem to be two ways in which one could take the categories to lead to the investigation of Z so conceived.

The first way, one might say, is from the very fact that there are categories; the second is from the priority of one category over the others.

The first way is what, it seemed to me, Aquinas was proposing in De Ente et Essentia. I gave a formulation yesterday, but here is another way of putting it:

We seem to incapable of considering that something exists, without supposing that it exists in one of the categories. We cannot even entertain the existence of something, without first thus classifying it. For instance, to consider the height of a horse, is already to be considering something distinct from the color of the horse. We couldn't be confused about whether we were investigating a quantity as opposed to a quality of the horse. This suggests that there is a deep connection between asserting the existence of a thing, and classifying it. We might then conclude that to assert the existence of a thing, just is to say that there is something about it such that it can be classified. Call this its ousia.

I asked whether there was warrant in Z1 for attributing an argument like this to Aristotle. After looking again at the chapter with this question in mind, I do not think that there is (although please feel free to disagree with me from your own examination of the chapter).

What I do find warrant for attributing to Aristotle, in Z1, is the following argument, which seems different from what Aquinas proposes. This argument hinges, not on the mere fact of the categories, but on the priority which the category named ousia enjoys relative to the others. This argument would proceed as follows.

To ask what ousia is, is to ask what truly or really (ontws) exists. We may understand this as: what especially (malista) exists. Let us approach this question through a consideration of the categories, since these involve predications of what 'is'. We see in that case that, although there are ten categories, the category of ousia is prior. In fact it is prior in all the ways in which one might wish to assert priority (as Z1 takes pains to observe). Thus ousia especially exists. However, a predicate which identifies the ousia of a thing tells us what, that is, what sort, it is (1028a14-18). Thus, what really exists is what makes a thing such that it can be sorted. To inquire into ousia, then, is to inquire into what it is about a thing which makes it such that it can be sorted. (And thus follows the investigation of Z.)

This latter argument does seem to me to be Aristotle's and to be found in Z1.

And this seems to me the correct way of approaching Z.

Two Concepts of Substance

I find that in discussions of the Categories there tends to be a lack of clarity about what Aristotle means by a primary substance. I shall therefore draw a distinction and then, by way of illustration, give a few texts in which this distinction seems to be fudged. I shall refer to the distinction as that between 'commonsense' and 'theoretical' primary substance.

A commonsense primary substance is what we would call a 'thing'. It is a particular to which we might give a proper name. E.g. this particular horse ('Secretariat') or this particular human ('Socrates').

A theoretical primary substance is a notion we arrive at by beginning with a commonsense primary substance, but then conceiving of it (somehow) in abstraction from any of the accidents that might belong to it. E.g. this instance of horse nature; this instance of human nature.
It makes sense that, on Aristotelian terms, there should be such entities as theoretical primary substances. After all, the category of substance is distinct from that of quality, quantity, relation, and so on. Therefore, the entity which is a substance would be distinct from the entities which are qualities, quantities, relations, and so on, inhering in that substance. The substance, then, would presumably be something that existed distinct from these other things.

Of course, one might wonder how there can be an instance of human nature which was not, however, determined yet in accordance with the other categories.

Now which of these does Aristotle mean when he talks of 'primary substances' in the Categories? The language he uses is indeterminate as between them. ho tis anthropos can mean either "The particular human" (in the ordinary sense of the term) or "The instance, man" (in the theoretical sense).

Now, as I said, I find unclarity when scholars refer to the primary substances of the Categories. Dan Devereux, for instance, refers to them as 'concrete particulars' and says such things as the following:
Although the species 'horse' has two substance-making features while the individual horse has only one, the individual horse (and not the species) is a primary substance because it is more of an underlying subject (162).
It looks as though by 'individual horse' he means a commonsense thing, such as Secretariat; and yet his language, I suppose, could be taken in the other way (although, admittedly, 'concrete particular' definitely suggests the commonsense notion).

S. Marc Cohen seems to go back and forth between both notions in his SEP article on Aristotle's Metaphysics. When he says:
The concepts of matter and form, as we noted, are absent from the Categories. Individual substances — this man or that horse — apart from their accidental characteristics — the qualities, etc., that inhere in them — are viewed in that work as essentially simple, unanalyzable atoms. Although there is metaphysical structure to the fact that, e.g., this horse is white (a certain quality inheres in a certain substance), the fact that this is a horse is a kind of brute fact, devoid of metaphysical structure.
He seems to be understanding primary substances as theoretical. And yet when he says, in the same article:
At the top (or trunk) of the tree are the most generic items in that category (e.g., in the case of the category of substance, the genus plant and the genus animal); branching below them are universals at the next highest level, and branching below these are found lower levels of universals, and so on, down to the lowest level universals (e.g., such infimae species as man and horse); at the lowest level — the leaves of the tree — are found the individual substances, e.g., this man, that horse, etc.
He seems to be understanding them as commonsensical. Surely 'this man' is something like Socrates, and 'this horse' is something like Secretariat.

Which is Aristotle's notion? This much, at least, is clear: if Aristotle's notion is of a 'theoretical' substance, then it would be natural for him to speak of 'the substance of' a thing (as he does, without explanation, in the Metaphysics)--because the substance of Secretariat would be the horse nature that Secretariat has; the substance of Socrates would be the human nature that Socrates has; etc.

I believe the most common view is that by 'primary substances' in the Categories Aristotle means the commonsensical sort. But that view has a big problem--doesn't it?--namely that a commonsensical substance is not only a substance: it has lots of accidents thrown in with it.

The Significance of Ousia

I'll give here the argument I mentioned in the previous post.

According to Aquinas, Aristotle begins Z by invoking the categories (or so one may speak, if one reads De Ente et Essentia, as I have suggested, as a brief commentary on Met. Z and L), in accordance with the strategy of beginning with what is 'more knowable' by us. Aquinas suggests that the behavior of the predicate o)/n, as shown in the ramification of its uses into the various categories, is more knowable than the behavior of ou)si/a:

Quia vero ex compositis simplicium cognitionem accipere debemus et ex posterioribus in priora devenire, ut, a facilioribus incipientes, convenientior fiat disciplina, ideo ex significatione entis ad significationem essentiae procedendum est.
But then, according to Aquinas, Aristotle uses the fact of the categories, as the basis for an argument about the signficance of ou)si/a. Here is his extremely economical presentation of the argument:
(*) Et quia, ut dictum est, ens hoc modo dictum dividitur per decem genera, oportet quod essentia significet aliquid commune omnibus naturis, per quas diversa entia in diversis generibus et speciebus collocantur, sicut humanitas est essentia hominis, et sic de aliis.
Aquinas then mentions various near equivalents, as he sees it, of essentia, namely, quiditas, quod quid erat esse, forma, natura:
Et quia illud, per quod res constituitur in proprio genere vel specie, est hoc quod significatur per diffinitionem indicantem quid est res, inde est quod nomen essentiae a philosophis in nomen quiditatis mutatur.

Et hoc est quod philosophus frequenter nominat quod quid erat esse, id est hoc per quod aliquid habet esse quid.

Dicitur etiam forma secundum quod per formam significatur certitudo uniuscuiusque rei, ut dicit Avicenna in II metaphysicae suae.

Hoc etiam alio nomine natura dicitur accipiendo naturam secundum primum modum illorum quattuor, quos Boethius in libro de duabus naturis assignat, secundum scilicet quod natura dicitur omne illud quod intellectu quoquo modo capi potest. Non enim res est intelligibilis nisi per diffinitionem et essentiam suam. Et sic etiam philosophus dicit in V metaphysicae quod omnis substantia est natura.
These then gets fairly naturally connected with 'definition':
Quiditatis vero nomen sumitur ex hoc, quod per diffinitionem significatur.
And it can be seen that Aquinas thereby wishes to explain which topics get covered in Z.

But what especially interests me is the argument (*) above. It seems to be something like:
  1. The various predications of 'is' correspond to the highest sorts.
  2. Thus, what is signified by 'is' is that which makes something such that it can be sorted (at all).
  3. Ousia is what is signified by 'is'.
  4. Thus, ousia is that which makes something such that it can be sorted.
Met. Z then becomes an investigation of what it is by which things are sorted; the above account explains why, in light of this, it deals with the topics it does; 'matter' (hule) would get brought in insofar as it is relevant to sorting something; and genos and katholou have to be dealt with, additionally, because they might look like they work in that way (What sorts something if not its genus--the very sort it belongs to?).

It may be seen that Aquinas does not take Z1's appeal to the categories, as does Burnyeat, to be a restriction of our attention to the first category: he thinks that the question, 'What is it which makes this such that it can be sorted?', may be asked of a thing in any category, although, to be sure, it is most properly asked of things in the first category.

Let me underline a point: argument (*) seems to me one of the more startling, interesting, and (if correct) important arguments I have encountered. I wonder if there is warrant in Z1 for ascribing it to Aristotle.

On Existence and Substance

This last weekend I picked up Thomas Aquinas, De Ente et Essentia, on the hunch that somehow it would be relevant to what I had been thinking about. I confess that I hadn't understood before the significance of this book, since I had in a fairly foolish way allowed myself to get misled by the common translation of the title (On Being and Essence).

This time I was astonished to find that Aquinas uses ens for o)/n, and essentia for ou)si/a. A scholar of Greek philosophy, then, would wish to understand the title as, "On Existence and Substance", or, perhaps, "On Being and Substantial Being".

When its theme is understood in that way, the opuscula acquires the appearance of, in effect, a brief and elegant commentary on Z and its relation to L. Furthermore, it is a commentary which is enlightening insofar as it builds on a tradition very different from ours, that is, the tradition of Arabic commentators.

I want to share with you an interesting argument from its beginning.

The opening chapter of Z, as you know, seems simply to repeat doctrine about the priority of substance among the categories. It is a puzzle, I think, how this chapter relates to the rest of the book, and I think it is fair to say that most commentators today treat Z as if it begins with chapter 3. Burnyeat for instance, although he comments on ch. 1, says that the chapter merely directs us to what sort of being should be the principal object of the following investigation, namely, 'substantial being': "The chapter explains why a treatise on being should concentrate on primary being" (Map 12).

Yet Aquinas in De Ente et Essentia thinks that there is an important argument implicit in Aristotle's opening appeal to the categories. On Aquinas' reading, this argument sets the direction for the investigations of Z and, indeed, even helps to explain what I've been wondering about, viz. precisely on what grounds perceptible substances are given so much attention in Z.

I've whet your curiosity, I hope. In a subsequent post, I'll say what that argument is.

In a Swamp, and Calling for Help

I've wandered out into the morass of Met. Z and find myself wondering how I got here. Looking back, I see the following. (What follows is a 'map into the swamp'. You might just wish to surf in fresher waters.)

[i] I was writing a review of a volume (OSAP Winter 2003) in which Dan Devereux's paper appeared on the relationship between Zeta and Eta. (That review should be coming out shortly in BMCR.) It was not that I was looking to find flaws in that paper. Devereux's paper involved some relatively close and interesting matters of interpretation, which it was not possible to discuss in the review; therefore, I took up some of them here.

[ii] I looked at two sorts of arguments that Devereux put forward, involving (i) redaction criticism and (ii) philosophical interpretation. I found Devereux's arguments interesting, as I said, and worthy of serious consideration--indeed, that is why I spent time on them. Yet it seemed to me in the end that all of these arguments were unpersuasive, and I gave my reasons why. (By the way, dear reader: I rely on you to point out where I am wrong. Do not forget that you would do me a favor by refuting me.)

[iii] Since Devereux had relied frequently upon Burnyeat as an authority, I looked briefly at Burnyeat's Map of Metaphysics Z. (I had read the Map several years ago, when it was a lengthy paper; I had not previously looked at it in book form.) I found that, as regards redaction-criticism, one of the unsound arguments that Devereux had drawn from Burnyeat (about en allois) had also been endorsed by Burnyeat. But I found that another argument (about the significance of the H1 summary) had effectively already been replied to by Burnyeat.

[iv] As regards philosophical interpretation, on the other hand, a difficulty in Burnyeat's general approach appeared to me, which I've tried to clarify in the last few posts. The problem has to do with why Aristotle spends the bulk of Z examining perceptible ('sensible') substances. Here is another way of putting the problem.

[v] As is well known, Aristotle describes what he is doing in the Metaphysics in two ways. He describes it as the study (i) of being qua being, and (ii) of imperceptible, separable substances. Now, as regards (i), it would seem misguided to restrict oneself to perceptible substances only, as this would be to 'cut off only a part of being' and study only that, rather than all of being. And, as regards (ii), clearly, the study of perceptible substances is not the study of imperceptible substances.

[vi] It is not clear to me that Burnyeat's interpretation can respond to this difficulty: Burnyeat says that Aristotle introduces the form-matter distinction in Z to reply to logicizing philosophers (as we may call them); but then we are left wondering how Aristotle's examination there of substances as having matter counts as metaphysics rather than physics. I used Burnyeat remarks on Lambda 1-5 to show that he does not succeed in explaining this.

[vii] The difficulty, in my view, becomes even worse, when one considers that Burnyeat argues in his Map that Zeta-Eta-Theta were written as a unit, that Lambda was tacked on later, and that it is, so to speak, extrinsic to those other books. It is unclear how, on this view, Aristotle in Z could be doing 'second philosophy for the purposes of first philosophy'. If there is no immediate and intended application of the results of Z to imperceptible substances, then how is it first philosophy?

[viii] I suppose Burnyeat could say that, on his interpretation, the conclusion 'form is substance' is exactly what is needed for the study of imperceptible substances--that is, Z establishes that substances can exist as pure forms, in establishing that form (alone) is substance. But then I wonder why Aristotle would take Platonizing or logicizing philosophers as his target in arguing for this sort of a conclusion. (Is that what they would find difficulty with?) Or, if you say that there is some special notion of form, not shared by them, that Aristotle wants to arrive at in Z, derived from the way that that notion gets used in the Physics--then, once again, the problem arises of how Z is different from physics. Also, it's not clear that there is any 'special notion of form' in Z except insofar as form is considered in its relation to matter--and yet then it appears to be a difficulty that Burnyeat wants to treat Z7-9, where form in its relation to matter is given thorough consideration, as an incongruent interpolation.

[ix] We could of course say that Aristotle is confused about his own distinction between first and second philosophy, or that the distinction doesn't amount to much in the end.

[x] And perhaps these are illusory problems, something that is hanging me up momentarily and that isn't very serious. My difficulties could easily be based on a misunderstanding. I present them simply as something troubling me for the moment.

[xi] Finally, when discussing Devereux on Z3, I proposed my own interpretation of the famous reductio there. I said that Aristotle was wishing there to draw a distinction between two senses of 'hypokeimenon'

(i) where the subject of predication is what is predicated of it (hypokeimenon 'as form' or 'as composite'); and
(ii) where the subject of predication is not what is predicated of it (hypokeimenon 'as matter');
and I said that the reductio of Z3 was meant to drive home the point that any intelligible use of (ii) presupposed a prior use of (i).

[xii] This suggestion (which, by the way, corresponds nicely to the back reference about the hypokeimenon, at Z 13.1038b2-6, and receives confirmation from that back reference), leads to an appealing simplification of the structure of Z, which is this.

[xiii] Of the four marks of substance which Aristotle presents at the beginning of Z3 (hypokeimenon, to ti en einai, katholou, genos), it is clear that Aristotle wishes to deal with the last two negatively, in order to reject them. What really needs to be explained, then, is Z3-11, which my distinction does:
Z3: distinction in senses of hypokeimenon
Z4-6: hypokeimenon as form (to ti en einai, called by Aristotle 'form')
Z7-9: hypokeimenon as composite and as proximate matter
(Z10-11: ancillary discussion of definition)
[xiv] My post pointing out that 'form' and 'matter' are not used by Aristotle in Z4-6 was meant to support this interpretation: 'form' is not used in Z4-6, I would suggest, because hypokeimenon 'as form' is precisely what Aristotle understands as the to ti en einai and is discussed through that phrase; and 'matter' is not used, because his discussion of hypokeimenon 'as (proximate) matter' and 'as composite' begins at Z7.

Now that I know where I am in this swamp, I'm radioing to be air-lifted out.
