Ethical Meanings of Substance

I think the ethical meanings of “substance” are more than just homonymous. Particularly, I have in mind the contrast of substance and accident. Traditionally, this is supposed to be an ontological distinction that builds on the logical one. I want to question that, not least because I don’t really believe that ontology as conventionally understood serves well for first philosophy, which ought to be more hermeneutic. That is something I’ve written about several times already.

Recently, we saw that a sharp distinction of substance and accident was important for Averroes, and for thinkers working in the broad tradition of Albert the Great. The ethical meanings of substance are related to that contrast.

Averroes probably thought the distinction between substance and accident was absolute. Following Hegel, I would instead relativize it. What is substance and what is accident can vary depending on context.

However, what I am inclined to call the fact that the distinction is only relative in no way detracts from its importance. In any context, we ought to focus on what is more essential. The contrast retains its value, even when we recognize that a strong enough accumulation of “accidents” can in some circumstances cease to seem accidental.

As an older person with short-term memory issues, I also take some solace in the circumstance that the things I am prone to forget are not matters of substance or essence or meaning, but only superficial “accidents” from the realm of events and utility. Individual events are ephemeral and strictly accidental in the Aristotelian sense. But what matters most is substance. (See also Essence and Explanation.)

Substantial Form?

One of the things I have learned recently is that the common scholastic (but post-Aristotelian) notion of substantial form goes back at least to Averroes. Aristotle talks separately about form and about substance, but never combines them in a single phrase like “substantial form”.

One of the important meanings of “substance” (ousia) is indeed form-like, as when he speaks of the what-it-is of things. Aristotle presents this meaning as superseding its more syntactic meaning of “underlying thing”. But eventually, this too is superseded by the uniquely Aristotelian notion of “act” (energeia), about which I have written much in the past year.

I’m now curious whether something like “substantial form” makes any appearance in the neoplatonic commentators like Simplicius and Philoponus. As Platonists, they would have an interest in turning the interpretation of substance back in the direction of form. (See also Substance, Essence, Form).

Identity, Difference, Reflection

Reflection is also the key to Hegel’s often misunderstood views on identity and difference.

“Reflection is the shining of essence within itself. Essence, as infinite immanent turning back is not immediate simplicity, but negative simplicity; it is a movement across moments that are distinct, is absolute mediation with itself. But in these moments it shines; the moments are, therefore, themselves determinations reflected into themselves” (Hegel, Logic, di Giovanni trans., p. 354, emphasis in original).

He goes on to discuss identity, difference, and the notorious “contradiction” as principal moments or determinations of reflection. Sometimes he uses these terms in the conventional way — of which he is highly critical — and sometimes he gives them his own meaning.

On Aristotelian grounds, I have long had doubts about appeals to an implicitly immediate simplicity or “identity” of substance in traditional metaphysics. I take these to be a form of Platonizing that originated in the neoplatonic commentaries on Aristotle. Hegel’s alternative suggestion of a “negative simplicity” seems much more plausible generally, as well as more consistent with the Aristotelian texts. We just have to get past the difficulty of Hegel’s idiosyncratic metaphorical straining of language about “negation”, and recognize that he is inventing ways to talk about the limits of representation, rather than grossly abusing the “classical” negation of formal logic.

Hegel’s remarks about identity are actually pretty clear, and worth quoting at length. As with negation, in Hegel identity, difference, and “contradiction” only have the meanings that they have in classical logic when he is pointing out their limitations. The alternative meanings that he actually endorses deeply reflect his critique of representationalism.

“In its positive formulation, A = A, [the principle of identity in classical logic] is at first no more than the expression of empty tautology. It is rightly said, therefore, that this law of thought is without content and that it leads nowhere. It is thus to an empty identity that they cling, those who take it to be something true, insisting that identity is not difference but that the two are different. They do not see that in saying, ‘Identity is different from difference’, they have thereby already said that identity is something different. And since this must also be conceded as the nature of identity, the implication is that to be different belongs to identity not externally, but within it, in its nature. — But, further, inasmuch as these same individuals hold firm to their unmoved identity, of which the opposite is difference, they do not see that they have thereby reduced it to a one-sided determinateness which, as such, has no truth. They are conceding that the principle of identity only expresses a one-sided determinateness, that it only contains formal truth, truth abstract and incomplete. — Immediately implied in this correct judgment, however, is that the truth is complete only in the unity of identity and difference, and, consequently, that it only consists in this unity. When asserting that formal identity is incomplete, there is vaguely present to one’s mind the totality, measured against which that identity is incomplete; but the moment one insists that identity is absolutely separate from difference and in this separation takes it to be something essential, valid, true, then what transpires from these two contradictory claims is only the failure to reconcile these two thoughts: that identity as abstract identity is essential, but that, as such, it is equally incomplete. What is lacking is awareness of the negative moment as [that by] which, in these claims, identity itself is displayed. — Or when this is said, that identity is identity essentially as separation from difference or in the separation from difference, then right there we have the expressed truth about it, namely that [formal] identity consists in being separation as such, or in being essentially in the separation, that is, it is nothing for itself but is rather moment of separation.”

“As to the other confirmation of the absolute truth of the principle of identity, this is made to rest on experience in so far as appeal is made to the experience of every consciousness; for anyone presented with this proposition, ‘A is A’, ‘a tree is a tree’, immediately grants it and is satisfied that the proposition is self-evident and in need of no further justification or demonstration.”

“On the one hand, this appeal to experience, that every consciousness acknowledges the principle universally, is a mere manner of speaking. For nobody will want to say that the abstract proposition, ‘A is A’, has actually been tried out in every consciousness. The appeal to actual experience is therefore not in earnest but is rather only an assurance that, if the experiment were made, universal acknowledgement of the proposition would be the result. — And if it is not the abstract proposition as such that is meant, but the proposition in concrete application, from which application the abstract proposition would then have to be developed, then the claim to the universality and immediacy of the latter would consist in the fact that every consciousness assumes it or implies it as a foundation, and indeed does so in every utterance. But the concrete and the application are precisely in the reference that connects simple identity with a manifold which is different from it. Expressed as a proposition, the concrete would be first of all a synthetic proposition. From this concrete itself, or from the synthetic proposition expressing it, abstraction could indeed extract the principle of identity through analysis; but, in actual fact, it would not then leave experience as it is but would have altered it, since in experience the identity was rather in unity with difference. And this is the immediate refutation if the claim that abstract identity is as such something true, for what transpires in experience is the verry opposite, namely identity only united with difference” (pp. 358-359, emphasis in original).

“Identity, instead of being in itself the truth and the absolute truth, is thus rather the opposite; instead of being the unmoved simple, it surpasses itself into the dissolution of itself.”

“More is entailed, therefore, in the form of the proposition expressing identity than simple, abstract identity; entailed by it is this pure movement of reflection in the course of which there emerges the other, but only as reflective shine, as immediately disappearing…. The propositional form can be regarded as the hidden necessity of adding to abstract identity the extra factor of that movement…. Consequently, if appeal is made to what appearance indicates, then the result is this: that in the expression of identity, difference also immediately emerges” (p. 360, emphasis in original).

“From this it is clear that the principle of identity itself, and still more the principle of contradiction, are not of merely analytical but of synthetic nature” (ibid, emphasis in original).

Here he uses Kant’s distinction of analytic from synthetic judgments. Analytic judgments are purely formal and tautological; canonically, the predicate is considered to be literally implied by the subject. Synthetic judgments on the other hand go beyond what is already implied by the subject or premises. This includes most judgments in ordinary experience. Synthetic judgments involve the material inference that Robert Brandom has particularly expounded in recent times.

“Thus the result of this consideration is this: (1) the principle of identity or contradiction, when meant to express merely abstract identity in opposition to difference as a truth, is not a law of thought but expresses rather the opposite of it; (2) these two principles contain more than is meant by them, namely this opposite, absolute difference itself” (p. 361, emphasis in original).

Ousia Energeia

Aristotle’s Metaphysics is arguably the single most important text in the history of philosophy, but even though on one level Aristotle’s writing is extremely clear and lucid, its deeper implications have been highly disputed. The great Iranian philosopher Avicenna is reported to have said that he read the Arabic translation of the Metaphysics 40 times without understanding it, and only began to understand after reading the commentary by Alfarabi. We are nearing the end of a long journey following what I think is a brilliantly innovative 21st century reading by Gwenaëlle Aubry. Here I’m covering the first half of her discussion of book Lambda chapter 7.

The title of this post is a phrase used by Aristotle to characterize the first cause. He distinguishes it as the ousia [“substance”] that, unlike other substances, simply “is” energeia [“act”]. The latter Greek term was coined by Aristotle, and the former was “substantially” redefined by him. I find it is best to put aside ordinary connotations of the English words for key philosophical terms like this (including “first cause”) — and to focus instead on the ways the philosopher himself uses them, along with what he says about them.

“Chapter 7 of book Lambda responds to the question, left in suspense, of the mode of relation of the first mover to the moved, and of the nature of its action. At the same time it exploits and deploys the ontological signification of energeia, designating in act the mode of being of the separate, and identifying it with the good and the end” (Aubry, Dieu san la puissance, 2nd ed., ch. 5, p. 184, emphasis added, my translation throughout).

“In so doing, it implies at the same time a distinction, absent from book Theta, between kinesis [motion] and energeia, the last being designated as the mode of being of the unmoved, even while maintaining a broad sense of energeia, understood not only as act and as a mode of being, but also as a certain activity (contemplation)” (ibid).

Aubry previously noted that Aristotle’s earliest use of energeia seems to have been in an ethical context. Here she points out that Aristotle is distinguishing between its better known physical sense (which already has a teleological element) and what she calls its ontological sense.

“The first lines of Lambda 7 mark a progress in relation to chapter 6, since they demonstrate not only the necessity of posing a principle that is act and not power in order to give an account of eternal motion, but also of that of thinking the first mover as unmoved” (ibid, emphasis added).

Within the context of Greek philosophy, the very idea of an unmoved mover is another extremely important Aristotelian invention. Plato speaks instead of a self-moving thing, thus postulating motion as an unexplained primitive attributed to something as a whole. He is not bothered by the unexplained primitive, because he sees becoming as fundamentally lacking intelligibility. For Aristotle on the other hand, motion ought to be explainable, and every explanation of motion also involves a passivity. To move in the colloquial English sense is always to be moved in Aristotle’s sense, by something, and we can give an account of this. It will turn out that the primary examples he gives of “movers” are the unmoved intelligible and desired things that serve to activate internal principles of motion in other things. But living beings such as animals also function as “moved movers”.

Aubry quotes Aristotle’s characterization of an unmoved mover as “being at the same time ousia and energeia” (p. 185). Aristotle makes a very compressed reference to his critique of Platonic “self-moving” in Physics book VIII. Anything we broadly call a “self” mover must be a moved mover, because it is implicitly moved by what it understands and desires. Any moved mover — and hence any self-mover — must be only an intermediary cause, and not an ultimate principle. Aristotle wants to very emphatically insist that the first cause is in the strict sense an unmoved mover, and not a self-mover in the broad sense that an animal is a self-mover. For him, any holistic “self-motion” necessarily involves the kind of mixture of activity and passivity that we attribute to an animal. Such a mixture is incompatible with the nature of the first cause.

“[I]t is because energeia is conceived here as ousia, and no longer as kinesis, that the first mover is unmoved” (ibid).

“This poses the question of how the unmoved can be the principle of movement. The demonstration this time proceeds in an indirect way: it consists in the premise according to which the desirable and the intelligible move [other things] without being moved, then in successive identifications, first of the real good with the desirable, then of simple and actual substance with the first intelligible, and finally of the first intelligible with the good. We then ought to conclude that the actual substance, itself already identified with the first mover, is identical with the intelligible and the good, and as such can move [other things] without being moved” (ibid).

She goes on to note that what allows these terms to be unified is really once again energeia, although at first it seems to be substance. This makes perfect sense, given the conclusions of book Eta.

“The unifying term of these identifications seems here to be that of substance. It is so nonetheless by the mediation of a double relation of anteriority: of substance itself, first of all, in the series of positive contraries; then, within substance, of substance that is simple and in act, haplo kai kat’energeian — or, more precisely, of substance that is simple insofar as it is said according to act. For it is this position of the preeminence of substance in the context of the series of intelligibles that justifies its identification not only with the good and the desirable, but with the better or that which is analogous to it. Thus it is once again the notion of energeia more than that of substance that appears as the conceptual mover of the demonstration, and as that from which the attributes of the principle can be deduced” (pp. 185-186, emphasis in original).

Just as Aristotle uses ousia or substance to explain our talk about being, he uses energeia or act to explain our talk about substance. And sometimes he even uses entelekheia or entelechy to explain our talk about act.

“Up to this point, Lambda 7 has established that the unmoved can be a mover, but not how it moves something else. Here again, the demonstration proceeds in an indirect way: it begins by establishing that there is also a final cause among unmoved things. In order to do this, we have to make precise what we mean by ‘final cause'” (p. 186).

“The text at this point poses a problem. Since antiquity, it has been reconstructed so as to coincide with parallel passages in Physics II and On the Soul II which, also relying on a pronominal distinction, distinguish between two senses of the final cause, that is to say to ou and to o, that which is envisaged and that for which something is — or, according to the traditional interpretation, the end of an action and its beneficiary. But neither of the senses thus distinguished can apply to the first mover: the latter cannot be conceived as the beneficiary of action, which would imply that it did not have its end in itself, and would thus be incompatible with its status as pure energeia. But it is equally difficult to conceive it as the end envisaged by action, since this would imply that the movement ends in it, or finds in it its term: the first mover would thus be the act and the end of eternal motion, and indeed of every moved being; thus conceived, the divine would be in sum the act of the world, or at least of the moved substances that make it up, whose separate existence would be explained only by the failure of their fusion with it” (pp. 186-187).

“The context of the distinction in On the Soul is nonetheless very close to that of the distinction of Lambda 7, since the text opposes on the one hand living things (plants and animals) considered as substances subject to the cycle of generation and corruption, and on the other hand the eternal and the divine…. Nonetheless, it does not aim to distinguish between an unmoved end and an end presupposing movement, but rather between an immediate and immanent end and a mediate and transcendent end. The first is identified with the soul, designated as being at the same time cause of motion, essence, and final cause…. The second is identified not with the divine itself, but with participation and community (koinonia) with it, and a community envisaged as continuous. Thus is explained the process of generation, which compensates for that of corruption: not being able to [persist indefinitely] as individuals, living things [persist] not in their numerical unity, but in the unity of their species. The object of their desire is thus not to be god but to participate in the divine, or in the mode of being that characterizes continuity and eternity. Or again, it is not to assimilate themselves to the divine form or the divine act, but rather to perpetuate their own form and act, in the way that the divine continually maintains its own” (p. 187, emphasis in original).

“But if read this way, as a distinction not between the end of action and its beneficiary, but between two kinds of end, the distinction in On the Soul seems reconcilable with that of Lambda 7, and to apply to the first unmoved mover: the latter should be understood neither as the immediate end of action nor as the one who attains that end, but as that which the moved substances aim at through their own proper ends” (pp. 187-188, emphasis added).

“The latter aim at no other end than themselves, and attain this immanent end by means of the different movements to which they are submitted, but through this end they aim also at the eternity and the necessity characteristic of the unmoved substance. As result, we can say that they are also moved by the unmoved, and again by the desire for unmovedness. We see that this interpretation agrees with the end of Lambda 7, as well as with Lambda 10’s reflection on the final cause and the good” (p. 188, emphasis added).

“The remainder of [Lambda 7] goes on precisely to mark the relation between unmovedness and necessity, at the same time as that between motion (even local) and contingency. This last point is the same that Theta 8 already underlined, but the demonstration relies no longer on the notion of dunamis understood as the power of contradiction, and indeed as the power to be or not-be, but on the notion of energeia. Unmovedness is deduced from this, and necessity in its turn from unmovedness. Here indeed, and for the first time, the ontological sense of energeia… excludes kinesis” (ibid).

She notes that Aristotle uses the grammatically dative from of energeia in the text here, which she has argued he consistently uses to distinguish what she calls the ontological sense of dynamis and energeia from their physical sense that is involved in the ordinary explanation of motion.

(I would add that this philosophical primacy of the dative form over the nominative in Aristotle is closely related to a perspective that puts adverbial phrases and relations ahead of nouns and verbs in the order of explanation. In fact, every noun or verb taken by itself is just a simple linguistic token that still has to be given an interpretation. No mere linguistic token by itself explains anything at all. By contrast, it is the non-simple character of relations — the fact that they already intrinsically “say something” about something — that gives them their fundamental role in interpretation and explanation.)

“If it is thus established that the unmoved can be an end…, it remains to know how it is, or to identify its proper mode of action, which is presented as valid for all final causes that exclude motion. Two words suffice to name this mode of action: hos eromenon [as being loved]. The hos does not introduce a metaphor, … but must be understood in the sense of ‘insofar as’: the unmoved mover moves without being moved, but ‘insofar as it is loved’. In its turn, the theme of eros has been prepared by the earlier reflection on the identity of the intelligible and the desirable, where it was said already that they move [other things] without being moved” (ibid).

“For the technical register that distinguishes between different species of desire, rational and irrational, is here substituted a broader term, eromenon. This term also has Platonic resonances: it evokes the amorous ascension of the Symposium, and recalls the figure of Eros, the daimon child of Penia and Poros, in whom are conjoined lack and abundance, absence and presence. Evoking Eros, nonetheless, Plato in the Symposium speaks of dunamis. Here, inversely, the erotic ascension has for its principle energeia. We see again in this point the rupture underlined in book capital Alpha, as in Lambda 6: to conceive the causality proper to the good, it is necessary to think it as a final cause, acting not as power but as act, and as the end of in-potentiality” (p. 189).

Aubry has consistently maintained that acting in the sense of having an effect is not reducible to the “action” of a power. All ordinary “action” is in reality a mixed form — an interaction — that includes an element of passivity. Pure act on the other hand is supposed to have an effect and to move other things, but without itself being involved in passivity. There is still an element of passivity in this case, but it is entirely on the side of the other things that are moved by what they understand and desire. Pure act for Aristotle is situated beyond the correlation of activity and passivity. Only where in-potentiality is also involved is there the ordinary interaction of activity and passivity that we experience in earthly happenings.

Rather than aiming to think pure presence, in the context of a human being even Plato is far more interested in mixed forms, as Paul Ricoeur has pointed out. Aristotle here takes up the Platonic theme of eros, while recasting it as an ascent toward pure act. But pure act is precisely not ever purely present to us. In the next post, we’ll see how Aristotle contrasts human life with the ideal life he attributes to the first cause.

Principles of Substance

“Chapter 5 of book Lambda constitutes a veritable pivot, not in the sense that, as the traditional reading would have it, it would bring to a close a hypothetical first part, or a treatise on sensible substances, in order to introduce a second part, or a treatise on separate substance, but because on the contrary it enunciates the principle of their continuity” (Aubry, Dieu san la puissance, 2nd ed., ch. 5, p. 173, my translation throughout).

“It is indeed in Lambda 5 that it is necessary to seek the key to the unity of book Lambda, and thereby of metaphysics, understood, according to the minimal definition suggested by Lambda 1, as a science distinct from both physics and theology; but equally, and this time against the onto-theological understanding of it, as a science that is not scissionable between a science of common being and a science of the first being — or this time between ontology and theology” (pp. 173-174).

“Lambda 5 in effect contains responses to two of the fundamental questions of Lambda 1, that is to say that of the nature of what is separate, and that of the unity of the principles of sensible substance. These responses are made possible by the results, both positive and negative, of the inquiries conducted in Lambda 2 through 4: the extension of dunamis to the eternal sensibles (Lambda 2); the exclusion of separate Forms (Lambda 3); the distinction between principle and element (Lambda 4). And they have one same term in common: that of energeia. Lambda 5 states in effect at the same time that dunamis and energeia are the common principles of all substances by analogy, and that the separate must be conceived as energeia and not as form. Proceeding from this, it remains for the following chapters, Lambda 6 through 10, to elucidate the nature of separate substance understood as ousia energeia, insofar as it at the same time is principle and cause of the other substances, and has a or some principle(s) in common with them — an elucidation which ultimately amounts to a deepening of the notion of the analogy” (p. 174, emphasis in original).

“As was already the case in Lambda 1, separation is here invoked as a criterion of substantiality, or according to the signification established in books Zeta and Eta, which substitutes for the Platonic idea of existence apart from sensibles that of the capacity for independent existence. This criterion allows us to recall the primacy of substance over the other categories, equally posed in Lambda 1, and thereby to affirm that the causes of substance are their causes as well” (ibid).

“For the term cause (aitia), we will proceed to substitute that of principle (arkhe), in order to declare that ‘it is in another manner again that the principles are the same by analogy, that is to say act and in-potentiality'” (ibid).

Aristotle’s four causes — originally introduced in the Physics — are extremely famous. But the above already suggests that in first philosophy, his “two principles” of act and potentiality will ultimately supersede them. In a simple way, act is the end, and that-for-the-sake-of-which; potentiality is the principle of motion. Form and matter provide overlapping specifications from a more static point of view, for which act and potentiality will again tend to be substituted. Such an overlap among the causes should be no surprise, since they are intended as complementary explanations. We have already seen, for example, that Aristotle’s hylomorphism leads him to ultimately assert the identity of an embodied form with its proximate matter. But I’m getting ahead of myself.

She refers to a passage that “in associating the couple of in-potentiality and act with that of matter and form, enunciates not an equivalence, but the rules of a substitution” (p. 175). Aristotle says “In effect, in act are the form, if it is separate, as well as the composite and privation (for example, obscurity or sickness), while the matter is in-potentiality, since it is capable of becoming the two contraries” (ibid). “Act indeed serves here to express form insofar as it is capable by itself, and not only in its articulation to matter, of an independent existence. This is a great novelty in relation to Zeta and Eta, where act served to name the composite as ousia malista [ousia most of all], as alone capable of independent existence, unlike form and matter taken in themselves. Far from being a simple equivalent, act expresses form insofar as it subsists” (pp. 175-176).

This is a somewhat subtle point, but clear enough. Things that are truly equivalent are bidirectionally interchangeable, without qualification. Here she is saying act expresses form only with additional qualification, which does not license a bidirectional substitution. In effect, we have a one-directional arrow between the two terms, rather than a two-directional one.

“In these lines, the notion of act reveals the ontological sense already distinguished in Theta. On the other hand, it does not have the axiological sense with which Theta 8 charged it, in establishing its equivalence with the notions of telos [end] and of ergon [completed work]. As in Theta 9, it applies also to privation, or to the negative contrary by which matter, like form, can be said to be in-potentiality. Applied to privation, the notion of act expresses again, and paradoxically, the mode of being and this non-being. As for the notion of in-potentiality, it expresses the mode of being of matter insofar as it is precisely capable of a double becoming, — toward form, or toward privation” (p. 176).

“To the notions of matter and form, those of in-potentiality and act thus bring an ontological supplement. There is something distinctive in them, allowing them to express beings where the matter and the form are not the same. It is not only a matter of illustrating the notion of analogy, as we did earlier, in pointing out that the relation between distinct matters and forms can be the same, but more of pointing out that the notions of in-potentiality and act apply not only in the context of a single substance, but between distinct substances, and more particularly between substances where one is the cause and the other the effect (we will see later, but Theta 8 has already apprised us that they also indicate, from the one to the other, a specific relation of causality, that is to say final causality)” (ibid, emphasis in original).

“The last lines of Lambda 5 contain a first response to the question of the unification of the principles of substance. Three kinds of unity are successively indicated, which nonetheless are conjoined:”

“–at the outset, a unity of a focal kind, which consists in the primacy of substance over the other categories, which has the effect that the causes of substance are aloso the causes of all otherr things;”

“–then a unity of an analogic kind, which constitutes the principal object of Lambda 4 and 5, and in virtue of which all beings, even if constituted from different elements, nevertheless have the same principles, that is to say matter, form, and the cause of motion;”

“–and finally, a direct or transitive causal unity, in virtue of which all things have for their cause ‘that which is first in entelechy'” (p. 177).

“This enumeration, we can see, mixes transitive principles and immanent principles. If it recalls the categories of matter and form, and not those of dunamis and energeia that the preceding developments have nonetheless substituted for them, it nonetheless makes the notion of entelekheia intervene, and applies it to the first cause. The latter is no longer mentioned only, as was the case at the end of Lambda 4, as ‘that which, as first of all, moves all things’, but as ‘that which is first in entelechy’. Act, designated this time by the term entelekheia and no longer that of energeia, taken indeed in its normative and axiological sense, which is no longer only ontological, appears from this point as the notion adequate to the designation of the first cause. We find thus suggested the possibility of its extension, which the remainder of Lambda accomplishes, from the corruptible and eternal movable substances to the unmoved substance — and, on this basis, of uncovering a principle common not only to the sensible substances as a whole, but to sensible substances and to the separate substance” (ibid, emphasis in original).

Separate Form?

“Lambda 3 goes on to show that form cannot be separate” (Aubry, Dieu san la puissance, 2nd ed., ch. 5, p. 168, my translation throughout).

I have always been rather baffled by interpretations of book Lambda that claimed to find evidence there that Aristotle finally revives the notion of separate form he so thoroughly refutes elsewhere.

“The first object of Lambda 3 is to examine the well-foundedness of the Platonic arguments in favor of the separation of form — or its pretension to the status of ousia [“substance”]. The permanence of form in generation can be invoked in support of such a thesis” (ibid).

“[F]orm, even if it well fits the Platonic criterion of ousia that is permanence, does not meet the specifically Aristotelian criteria. Here the appeal will be to that of tode ti, of being a ‘this'” (ibid).

“[T]he text opens with a new formula of change, which, contrary to the previous ones, takes into account its cause” (ibid).

As Sachs renders the full passage that she cites in part, “For with everything, something changes, by the action of something, and into something: that by the action of which it changes is the first thing that sets it in motion, that which changes is the material, and that into which it changes is the form. For it comes into being either by art or by nature, or else by fortune or chance. And next after this is the fact that each independent thing comes into being from something that has the same name (for this is true both of natural independent things and of the rest). Now art is a source that is something else, but nature is a source that is in the thing itself (since a human being begets a human being), while the rest of the causes are deprivations of these” (Metaphysics, p. 233).

Aubry notes that this language appears to be a bit of a regression, since matter has already been superseded by potentiality in Lambda chapter 2. But she explains that chapters 2 and 3 constitute a pair concerned respectively with matter and form, and chapter 2 did not yet address form.

She points out that Aristotle goes on to mention three kinds of substance, among which form is conspicuously not included. “What are enumerated are matter, which is only in appearance a tode ti; phusis [nature], which is at the same time a tode ti and a hexis [acquired disposition]; and finally, the composite, or individual realities, the kath ekasta like Socrates and Callias. Where we might expect the term form, we instead find that of phusis, which will be qualified again as hexis. For phusis is precisely a form realized in a matter, stabilized as hexis at the end of a process. Such an enumeration already signals that form as such cannot be counted as ousia, and cannot be separate, in the sense that it does not exist apart from the composite” (p. 169).

“In Zeta 8, it was already the intervention of the criterion of tode ti that allowed it to be established that form does not exist apart from (para) the composite, and thus to reject as superfluous the hypothesis of the Platonic Forms, since, at least in the case of natural beings, it is indeed an individual — and a concrete composite — that engenders another. But besides Zeta 8, it is necessary to refer equally to Eta 1…. Eta 1 makes intervene, in addition to the criterion of tode ti, the criterion of khoriston, which, as we have underlined, is equally present in Lambda 1. The examination established that matter is only a tode ti in-potentiality, dunamei; while form is only [a tode ti] insofar as it is to logo khoriston [separate according to the formula, or in speech]; and only the composite is khoriston haplos [separate simply]” (pp. 169-170).

“Like the criterion of khoriston and even dissociated from it, the criterion of individuality indeed leads to only counting the composite of matter and form as ousia” (p. 170).

“[I]n the case of art, there can be form without matter, but the form thus considered is nothing but tekhne [art] itself, that is to say in fact the form such as it is conceived and envisioned by the artisan. In the case of phusis, the principle of synonymy, the permanence of one same form transmitted from one individual to another, is sufficient to explain how we are led, as Plato did, to assert that there exist distinct forms of natural substances. But we can conclude from this neither that they are separate, nor that their character is that of tode ti and of ousia.”

“This would presuppose that the forms exist apart from and independent of composites, and in particular that they are capable of pre-existing as well as perhaps surviving them. But in truth, the existence of the formal cause is simultaneous with that of the composite. Certainly health is distinct from the healthy, and sphericity from the bronze sphere, but health and sphericity do not have full existence, that is to say do not exist as ousia except as instantiated in the cured patient, the completed sphere” (ibid).

“At the end of the whole formed by Lambda 2 and 3, we are indeed in possession of a positive result: matter, conceived kata dunamei, can be extended from the corruptible sensibles to the eternal sensibles; but also a negative result: form cannot be separate. Each of these results already contains elements of a response to the guiding questions posed in Lambda 1: whether or not it is possible to unify the principles of substance; and the nature of the separate. One term is still missing: that of energeia, in which will reside the definitive response to these two questions” (p. 171).

In discussing Lambda 2, she emphasized the substitution of potentiality for matter. Here in passing she suggests that alternatively, we could consider that matter has been redefined along with potentiality. But which alternative we endorse is really just a question of the optimal use of words. The old understanding of both matter and potentiality has been left behind.

Potentiality in the Stars

“Lambda 2 marks the irruption in Metaphysics Lambda of the notions of dunamis and energeia, at the same time as the passage from doxographic examination to the thetic moment” (Aubry, Dieu san la puissance, 2nd ed., ch. 5, p. 165, my translation throughout). Aristotle’s distinctive concepts of potentiality and act had been absent from chapter 1’s preliminary survey of the opinions of others, but as soon as he begins to elaborate his own proper theses, they reappear.

“Lambda 2 proceeds also to a substitution: that of the couple dunamei/energeia for the triplicity of matter and the contraries. It is necessary to note — and this is an essential point — that here in what is their first occurrence in Lambda, these notions intervene straightaway under their dative form, and as a division of being: ‘For, since being is double, everything changes from being in-potentiality to being in-act’…. the dative form marking the ontological sense more specifically” (ibid).

Aristotle is not abolishing matter in the modern sense. Replacing stuff with a modality like potentiality would seem rather odd, but that is not what is occurring here. Hylomorphism means that any kind of “stuff” must already be body — and thus for Aristotle must be a “composite” of form and matter. He never treats form and matter as discrete parts of a thing, and repeatedly insists that they can only be separated by abstraction. Aristotelian matter in itself has always struck me as principally specifying a kind of primordial adverbiality and relationality involved in any embodiment.

Here he is moving yet further away from the “grammatical prejudice” of an underlying thing in which properties inhere. The whole dialectical development of the concept of “substance” (ousia) in the Zeta-Eta-Theta sequence and book Lambda precisely involves moving beyond the notion of something “underlying” that we naturally begin with in thinking about how things persist through time. Here we see a related movement beyond the abstraction that Aristotle calls matter, which was the initial candidate for something underlying.

“Lambda 2 takes metabole [change] as its primary object. It proposes an analysis appropriate to all kinds of change, and in particular both substantial change and change of position…. More precisely, it is a matter of identifying the principles common to all sensible and movable substances, whether they are eternal [astronomical] or corruptible [earthly]. For it is the intervention of the notion of dunamei and its substitution for that of matter, that makes possible this unification of the principles of sensible substance” (ibid).

“The text finds a precise parallel in book I of the Physics, where the same three formulae succeed one another: the contraries and their subject; matter, form, and privation; and finally, the formula according to power and act, kata ten dunamin kai ten energeian. Nonetheless, in Physics I the last is mentioned as having been treated elsewhere with more precision. Still it reappears at the end of that book, in the context of a critique of the Platonic theory of matter: Plato erroneously identifies matter with non-being, with evil and privation…. That which desires the positive contrary must be matter, as distinct from one and the other contrary. Matter must therefore be distinguished from privation: the latter is in itself the principle of corruption. On the other hand, if we consider it according to power, kata ten dunamin, matter is unengendered and incorruptible” (pp. 165-166).

“The last lines of book I of the Physics considerably clarify chapter 2, but also 3, of Lambda, in that they designate two distinct modes of approach to the material and formal principles: the perishable forms are in effect called ‘physical’, and the study of the others is deferred to first philosophy. But this distinction applies also to matter: in fact, we distinguish equally between corruptible matter and incorruptible matter. For unengendered and incorruptible matter is identified with matter considered kata dunamin, or according to a point of view that, without having been explicitly named, has nonetheless been distinguished from the physical point of view” (p. 166).

Modern physics and chemistry speak of an ultimate conservation of matter.

“The fact is that over the course of Lambda 2, the couple of in-potentiality and act is substituted for the triad of matter and the contraries. Thus change is no longer presented as the transition of matter from one contrary to another, but as a passage ‘from being in-potentiality to being in-act’. For to treat it thus is to underline, as the end of Physics I already has against Plato, that even in the case of generation, metabole does not have for its principle absolute non-being, but being in-potentiality. And it is also to underline, this time against [the Ionian philosophers of nature], that in-potentiality in its turn is for a determinate being” (pp. 166-167).

“But beyond these polemical stakes, the substitution of the couple of in-potentiality and act for the triad of matter and the contraries makes possible a formula of change that is valid for all the movable substances, whether they are corruptible or incorruptible” (p. 167).

“Thus conceived, kata dunamin or again dunamei, matter appears no longer as a physical component but as a metaphysical principle, valid as much for the corruptible sensibles as for the eternal sensibles” (ibid).

A component suggests something mutually exclusive with other components, while a principle affects the whole of something. Potentiality is neither a component nor an underlying thing.

This “marks a progress from Theta 8: in fact, there energeia is found attributed to the eternal sensibles, but dissociated from dunamis, since the latter was understood as the power of contradiction, and treated as definitional of the corruptible sensibles. Now we discover that it is not only act, but also in-potentiality that… admits an extension from the corruptible sensibles to the eternal sensibles” (ibid).

The “power of contradiction” would be a power to be or not to be something. Unlike earthly things, Aristotle sees the stars as moving in an unchanging way, and as not changing in their being in doing so. Since they are involved in motion from place to place, I was previously surprised by Aristotle’s remark in Theta 8 that seemed to say that eternal sensibles have no potentiality. Now we see that after all they do have potentiality, in the way that he has redefined it here.

Physics and Theology

Returning to Gwenaëlle Aubry’s landmark new reading of Aristotle’s Metaphysics, last time I covered her preliminary roadmap of book Lambda, in which Aristotle discusses the first cause and its relation to the world. Here I will focus on her discussion of chapter 1.

As is common in Aristotelian treatises, Lambda begins with a survey of the opinions Aristotle deems most important and relevant in this area — namely the “physical” approach of the Ionian philosophers of nature, and the “logical” one he attributes to the Platonists. Aristotle will borrow from both, and criticize both.

At the same time, Chapter 1 outlines a program of investigation that will be pursued over the course of the book. This consists of four questions:

1) How are cause (aitia), principle (arkhe), and element (stoikheion) distinguished, and how are they related?

2) Are there principles common to both eternal (astronomical) and corruptible (earthly) sensible substances?

3) How are we to understand the meaning of unmoved substance?

4) Are there principles common to unmoved substance and to eternal and corruptible sensible substances?

The Ionians and the Platonists agree, each in their own way, that it is principally of “substance” (ousia) that we investigate the principles and causes, though they interpret substance differently. Aristotle retrospectively interprets both the Ionians and the Platonists as reaching toward his own notion of substance and its role — i.e., as dwelling on questions about what things are, and about why things are the way they are.

It is the “things” in life that are of primary interest, because to a greater or lesser degree they all have persistence, and therefore also have recurring relevance in their own right. Mere transient events only have relevance to meaning and deeper truth insofar as they may be claimed to show something about recurringly relevant things.

Aubry points out that in book Lambda, it will not be a question of demonstrating the primacy of substance and of independent things over those other “things” that are attributed to them. Something like book Gamma’s argument for the methodological priority of inquiry into relatively independent things seems to be presupposed. Nor does Lambda ask what substance is, as book Zeta does. The specifically Aristotelian sense of substance’s defining criterion of “separateness” — embodied in the relative independence of some but not all of what we call “things” in the broadest sense — which was a major result of Zeta, is recalled in the opening lines of the chapter here, and is thus integrated into Lambda’s inquiry from the beginning. But Zeta’s investigations are also deepened here by a new connection with book Epsilon’s emphasis on causes and principles, so that we now also ask, what are the causes and principles of substance? Moreover, questions raised but unanswered at the end of Zeta about unmoved substance will eventually be addressed here.

Aristotle contrasts the Ionian view of the world of becoming as a certain (material) whole with that of the Platonists, who treat it as a pure succession of phenomenal instantiations of immaterial Forms. The Ionians recognize as principles only the elements of bodies, thus putting all intelligibility on the side of matter. The Platonists recognize only immaterial Forms as principles, and hold becoming as such to fundamentally lack intelligibility.

“Going forward, the opposition between holists and episodics does not outline the alternative according to which the arguments of Lambda will be deployed, but rather, conversely, that which it will be necessary to overcome” (Aubry, Dieu san la puissance, 2nd ed., ch. 5, p. 161, my translation throughout).

In a second contrast between the Ionians and the Platonists, the Platonists associate substance exclusively with what is logically universal (katholou; literally “according to the whole”), but the Ionians associate it exclusively with concrete individual things (kath ekasta; literally “according to each”). Aristotle will bridge this gap too, by posing the first cause as not itself a logical universal, but rather as a unique thing, to which all other things universally have a broadly similar constitutive relation.

Finally, Aubry refers to the passage, “And the former kind belongs to the study of nature (since they include motion), but this kind belongs to a different study, if [ei] there is no source [principle] common to them” (Metaphysics, Sachs tr., p. 231). Scholars have debated the significance of Aristotle’s ei here.

“The translation [of the ei] adopted here [and independently by Sachs] results in a hypothetical meaning, ‘if’, but another reading gives it a causal meaning, ‘since’. Such a divergence is far from being minor. The traditional causal reading of the ei in effect founds a scissionist interpretation of metaphysics, which will be divided between the science of sensible substances, or physics, and ‘another science’, having for its object the unique substance that is separate [in the Platonic sense of separation from matter], which going forward will be identified with theology…. As well as a scissionist reading of metaphysics, these lines invite a hybrid reading of Lambda according to which it is necessary to distinguish between a treatise on sensible substances, and a treatise on substance that is separate [again in the Platonic sense]. Such an interpretation amounts to abandoning any project for a general ontology — eventually only leaving place for a unification from above, that is to say by theology, applied to [the emphasis on causes and principles from] book Epsilon chapter 1″ (Aubry, p. 163).

She cites a survey of this issue by David Lefebvre, but does not directly identify sources for the traditional interpretation. Since the dispute is about a detail of the Greek text though, I would presume that these are traditionally minded modern scholars, and not medieval writers.

“On the other hand, the hypothetical reading of ei leaves open the possibility that there exists a common principle [of sensible and Platonically “separate” substance], and, going forward, also a common science of all the substances, sensible and separate. Nonetheless, this hypothetical reading admits in its turn of two distinct interpretations: one could understand that the common science of all the substances is to be identified with physics; or again that it is the alternative ‘physics’/’different science’ that is itself conditioned by the [presumed] eventual absence of common principles, but that under the hypothesis that such principles exist, this partition can be superseded, to the profit of a unique science of substances — a unique science that can be reduced neither to physics nor to theology” (p. 163-164).

The key point that should be emphasized is that Lambda aims to sketch the basis of a unified account of all substance.

I would go somewhat beyond the scope of Aubry’s argument here, to also question the traditional talk about “sciences” in this context. Aristotle himself simply speaks of knowledge (which we could gloss, following the broader of his usages, as an interpretive account grounded in reasoned explanation). This presupposes rather less than either the ideal of foundational demonstrative science bequeathed to later traditions by Alfarabi, or the whole elaborated apparatus of empirical science, with which “science” is identified in most modern contexts.

I also question the identification of Aristotle’s more specific “ousiology” or account of substance with “ontology”, or the alleged science of being. Properly speaking, we owe the latter to successive post-Aristotelian elaborations, principally by Avicenna, Duns Scotus, and Christian Wolff — however often these elaborations get retrospectively read back into the Aristotelian text. Aristotle does indeed refer without prejudice to the question whether knowledge of being “full stop” is possible, but his eventual answer is the more limited one that a general reasoned account of ousia is possible. I think it shows the original naive question about being to have been badly posed. That way of posing it leads to other nonsensical, non-Aristotelian questions that imply category mistakes, like “why is there being?”

Finally, I give more weight to the fact that the term “metaphysics” is never used by Aristotle, and was only first applied to the collection of treatises we know by that name by an editor, long after Aristotle’s death. I prefer Aristotle’s own term “first philosophy”.

But I do very strongly agree with Aubry that book Lambda is intended to develop what could reasonably be called a general ousiology, embracing both sensible and Platonically “separate” substance; and moreover, that this ousiology has a fundamentally axiological or value-oriented character.

Book Lambda: Introduction

“Book Lambda of the Metaphysics responds to the exigencies defined in book capital Alpha: to pose the good as a principle; and to determine its proper mode of causality as being that of a final cause, and not an efficient or formal cause. These two exigencies are resolved in a single proposition: the principle is act, and is without power. Act here receives its full signification: it is act and not form that is the mode of being of separate substance; but act also serves to name the good as a principle” (Gwenaëlle Aubry, Dieu san la puissance, 2nd ed., ch. 5, p. 153, my translation throughout).

We saw last time that pure act (energeia) for Aristotle — unlike any being in subcelestial nature — has the character of unmixed necessity. This is true because pure act is the only thing that fully is what it is. It is the admixture of power (dynamis) and in-potentiality (dynamei) in other things that is the source of their contingency, as not being pure act.

“If the concepts of dunamis and energeia simultaneously unify ousiology and integrate theology into it, they also bear all the singularity of the Aristotelian thought of being, and within it of the first being, insofar as the latter is conceived not as an excess of power, but as the reality of the good” (p. 154).

Ousiology would be an account of ousia, or what we call “substance” from the Latin. Again, the first cause is not first in the sense of time, but first in the sense that all other things depend on it. The whole point of calling it pure act is to separate it from the contingency of the dependent things that have power and potentiality.

The very idea of an “excess of power” is utterly alien to Aristotle. We saw before that he understands power as always being power for something definite. Only those things that also have a dependency on something outside of themselves have this kind of “power” at all, corresponding to an unrealized in-potentiality. This “power” and potentiality are the mark of their contingency, not of implacable might.

It is Plato and Plotinus who on the other hand associate superlative power with the Good or the One. But Aristotle criticizes Plato for failing to explain how the Good acts as a cause. Then Plotinus later attempts to answer Aristotle’s criticism by adapting and dwelling upon the novel theme of the excessive character of the One’s power that first emerges in the Judeo-Christian tradition.

“To read book Lambda in a unitary manner, and to find this unity in ontology, that is to say in the sense of being that dunamis and energeia express, is not at all to deny or to minimize its theological content. It is on the contrary to affirm the unity of metaphysics, against the onto-theological readings that scission it between a science of common being and a science of the first being. It is also to recognize a continuity among the different treatises that have come down to us under the name of the Metaphysics” (p. 156).

“The date of composition of book Lambda is debated by commentators. But it is necessary in any case to distinguish between the historical question of its editorial status and that of its conceptual relation to the other books of the Metaphysics, with regard to the problems to which responds to, displaces, or resolves, the analyses that it deepens” (ibid).

“The problems treated in the central books [Zeta–Eta–Theta], and most especially in book Theta, seem to us to be decisive. In Lambda, the elucidation of [1] the ontological sense of dunamis and energeia that orients Theta in its entirety; [2] the analogical relation between them in Theta 6; and [3] the anteriority of act over in-potentiality subsequently developed in Theta 8, furnish the conceptual basis as much for the analogical unification of the principles of substance, as for the principal position of ousia energeia” (ibid).

“Massively mobilized in Lambda 6 and 7, [the notions of dunamis and energeia] are absent from the introductory chapter that constitutes Lambda 1, as from the analyses of Lambda 3, and little present in Lambda 8 and 10. Nonetheless, the successive and modulated interventions of dunamis–energeia (or — and it is necessary for us to ask ourselves about this variation, of their dative form dunamei–energeia) over the course of Lambda serve each time to respond to the different questions raised in Lambda 1, which serve as the program for the book in its entirety: what is a principle (notably in its difference from an element, stoicheion, or a cause, aitia)? What are the principles common to sensible substances? What is the nature of separate substance (is it a form or not)? Finally, and these two questions are intrinsically linked, in what way is separate substance a cause, and are there principles common to all substances, sensible or separate?” (p. 157).

Here Aubry notes that while still maintaining his own preferred sense of “separate” ousia (separate as subsisting with relative independence with respect to other things) as distinct from that of Plato (separate as independent of matter subject to becoming), Aristotle nonetheless in this part of the text turns to ask questions about substance that is separate in both of these senses.

“Going forward, we will be able to extract a unitary principle for all substances, sensible or separate, that is not reducible to the unity of the material composite; and at the same time to maintain, under the auspices of this unity, a hierarchy that is not episodic or disjunctive” (p. 158).

What makes the hierarchy of substance not episodic or disjunctive in Aristotle is the explanation he provides for the mode of causality of the end and the good as that for the sake of which.

“Lambda 2 will thus substitute the notion of in-potentiality for that of matter, in order to extend it, beyond the corruptible sensible substances, to the eternal sensible substances. This positive result is followed in Lambda 3 by a negative, but decisive, result, since we will establish, against Plato, that form cannot be separate. In Lambda 4, it is this time against its reduction to an element [i.e., a constituent in the material sense] by those who wrote about nature, that the notion of principle will be redefined” (ibid).

For Aristotle, a principle of something is never reducible to a constituent part of it, and what any given thing “is” is always more than a mere sum of its parts.

“The veritable pivot of book Lambda, chapter 5 goes on to integrate these various results, negative as well as positive: the extension of dunamis to the eternal sensibles; the exclusion of form from consideration as the mode of the being of the separate; the distinction between principle and element; and going forward, [chapter 5] brings two fundamental responses to the questions posed in the introductory chapter: separate substance must be conceived as act and not as form; and dunamis and energeia are, by analogy, the principles common to all sensible substances” (ibid).

“On this basis, the central concern of chapters 6-10 will consist in determining and exploring the mode(s) of relation between separate substance and the other substances. Lambda 6 having demonstrated that separate substance as ousia energeia is the condition of the movement of the other substances, it remains to identify its mode of causality as being that of the end (Lambda 7) and of the good (Lambda 9), but also the way in which this causality operates in the case of the eternal sensibles (Lambda 8), and, finally, the whole universe (Lambda 10)” (ibid).

The whole universe coheres intelligibly, both insofar as it realizes the good, and insofar there are also explanations when things fall short or go wrong. The world we live in is not a mere whole made up of discrete parts, as the pre-Socratic writers on nature tended to assume. Neither is it the mere sequence of disconnected episodes that follows from the Platonic sole emphasis on what Aristotle calls formal causes.

Grammatical Prejudice?

In several of his works, Nietzsche attacks the “grammatical prejudice” or “superstition of logicians” in positing a doer behind the deed. For example:

“‘[T]he doer’ is merely a fiction added to the deed — the deed is everything. The popular mind in fact doubles the deed; when it sees the lightning flash, it is the deed of a deed: it posits the same event first as cause and then a second time as its effect. Scientists do no better when they say ‘force moves’, ‘force causes’, and the like” (Genealogy of Morals, 1st essay, section 13, Kaufman tr., p. 45).

One of the more obvious targets of this polemic would seem to be a certain stereotypical Aristotelianism. Such a view would take Aristotle’s more superficial characterization of “substance” [ousia] as the “underlying thing” as a final truth. As Nietzsche points out, this view has very wide diffusion, and has come to be regarded as common sense.

We have seen in some detail, however, that in his more advanced thought in the Metaphysics, Aristotle explicitly inverts this popular prejudice, and makes act [energeia] the criterion of what is a substance most of all [ousia malista]. As Goethe said, “In the beginning was the deed”.

Contrary to Nietzsche though, this does not make of substance a mere fiction. For Aristotle, substance is ultimately a result rather than a starting point. It turns out to be a derived concept, rather than an elementary one as may first appear. But as a result and as a derived concept, it has legitimate use.

Even the great 20th century Thomist Etienne Gilson suggests in his Being and Some Philosophers that we should think of being as a verb rather than as a noun. I too keep harping on the fact that all the many “senses of being” Aristotle enumerates in book Delta of the Metaphysics are senses of the connective “is”. But this is not the end of the story either.

The next thing we should notice is that what Aristotle principally enumerates and emphasizes in book Delta and elsewhere are the senses of being in which we say something “is” something (else) in accordance with one of the categories. These are transitive (connective) senses of “is”, associable with the formation of propositions that could be evaluated as true or false. Behind Aristotle’s talk about being is a guiding concern with normative saying and intelligible explanation of what properly speaking “is” the case. With his Thomistic roots, Gilson on the other hand emphasizes an intransitive sense of being as “existing”.

In numerous passages in the Metaphysics, Aristotle does indeed use “being” in an intransitive way, but my contention is that this is by way of summary or a kind of shorthand, which should be understood as presupposing and referring back to something like the enumeration of senses of being that we actually find in book Delta, all of which I would contend are transitive.

The only apparent exception in Delta is none other than being in the sense of in-act and in-potentiality. This occurs at the very end of the enumeration, and can reasonably be interpreted as shorthand for the longer expressions used earlier. Moreover, the detailed discussion of being in-act and in-potentiality in book Theta is about something (transitively) being something definite in-act or in-potentiality. In Delta, I think the brief mention of being in-act and in-potentiality is to be understood as wrapping a modal dimension around the more basic saying of “is” in the senses of the Categories. (Here I have passed over other senses of being that Aristotle himself says are less important, but none of these corresponds to what the scholastics and the moderns call existence either.)

Perhaps Gilson is right that Aquinas can be read as a sort of “existentialist”. But relatively speaking, I think Aristotle himself is closer to the analytic and continental philosophers who have emphasized the importance of language, meaning, and discourse. (See also Being as Such?.)
