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).

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.
