The remainder of Aubry’s third chapter analyzes book Eta of the Metaphysics, following on her analysis of book Zeta.

In Zeta, matter had been dismissed as a candidate for ousia or “substance” taken simply. But Eta chapter 1 “allows matter to be characterized not simply as ousia, but as ousia in potentiality. And in its turn, it invites us to consider not simply ousia but ousia as act” (Dieu sans la puissance, 2nd ed., p. 89, my translation throughout).

“In the text that follows, the term energeia [act] is found systematically associated with that of eidos [form]” (ibid). “Energeia thus inherits, in Eta, all the characteristics of eidos brought to light in Zeta” (ibid).

“What Eta 3 shows, nonetheless, is that it is not always easy to distinguish the act from the composite: for example, does the term ‘house’ designate ‘a shelter made of bricks and stones in such and such a way’, or only a shelter? The term ‘animal’, a soul in a body or a soul? It appears that the distinction between material element and formal element has something artificial about it; form is not only that which makes the stones erected into walls, the wood made into a roof, into a house: it is the very organization of the stones into walls, of the wood into a roof (and in the same way, the soul is not superimposed on a body that would be already provided with organs, already able to grow, to be nourished, to move, etc.: it is that very organization and those very capacities. Thus, the composite substance is a unity, the unity of the material element and the formal element — and in such a way that it can be called an entelechy, and a certain nature” (ibid).

(I would say it is really the entelechy of a composite substance — its embodied, realized, and continuing purpose — that gives it unity, and makes it a substance in the Aristotelian sense at all. Any ousia involves stronger unity than a mere coexistence of elements. Entelechy is a higher-order persistence of purpose and its realization that explains the unity of a substance. The stronger degrees of unity that we see in living things and artifacts don’t just happen, and knowledge of them isn’t just somehow immediately given. Entelechy expresses the intelligible cause or reason for there being a unity strong enough to be called a substance. Perhaps we might even say that entelechy is a final cause in act. Every Aristotelian substance would in this way be an end unto itself. Kant explained respect for others in terms of regarding the other as an end in herself. Thus I think Kantian respect ought to apply to all Aristotelian substances.)

“To this, Eta 4 adds that just any thing cannot have just any matter” (p. 90). “It thus appears that, considered as potentiality, matter is an element of substance, and that if it is determined by form, it is a determiner also” (ibid).

So here we have a clear expression of reciprocal determination between form and matter. (Aristotle’s biological works contain many other examples of this.) She quotes from Eta 6 that “the most proximate matter of a thing and its form are one and the same thing” (p. 91). The mutual determination noted above is why that is true.

“Adopting the language of in potentiality and in act is indeed to think the unity of what the Platonic and abstract language of matter and form invites us to distinguish” (p. 91).

“Potentiality is the unity of the matter and the form seen from the side of the matter, act the unity of the matter and the form seen from the side of the form. Matter and form are nothing but abstract points of view adopted toward the concrete individual” (ibid, emphasis in original).

The superficial clarity of quasi-syntactic distinctions between matter and form is belied by the reality of mutual determination that underlies the Aristotelian thesis of hylomorphism.

“Eta does not just repeat the analysis of Zeta while modifying the terms: in substituting the etiological point of view for the logical one, … it offers a solution, which will again be completed in Theta, and will only acquire its full meaning in Lambda, to the problem of ousia” (ibid).

What she calls the etiological point of view consists in explanation in terms of Aristotelian causes or “reasons why” — especially final causes, or internal teleology — and may include an aspect of process. What she calls the logical point of view consists in what I called quasi-syntactic distinctions between matter and form, which are purely static.

“Ousia is neither the matter nor the form, it is the composite, but it is also the matter as potentiality for the form, the form as in-act in a matter — the two constituting the unity of an individual at the same time determinate and separable. Act responds in fact to all the criteria of ousia: insofar as it inherits the characteristics of form, it says determination and permanence; insofar as it names the form as linked to a matter, it says also the individual and the separate. Act indeed says ousia at the same time as substance and as essence…. Through the notion of act, the conflict with which Zeta ended, between the Platonic criterion and the Aristotelian criterion for ousia, between ousia prote and ousia malista, and also between the candidate of form and the candidate of the composite, is indeed found to be resolved” (pp. 91-92).

Although my own readings here of Zeta and Eta did not catch the nuance of the prote/malista distinction that Aubry makes a good case for based on the Greek text, my general sense of the respective results of Zeta and Eta is quite similar to hers. The long development of Zeta ends — and Eta begins — with an unresolved tension between the requirements of knowledge, and what I would call an ultimately ethical focus on independent things as concrete wholes. Eta ends up much more optimistically suggesting that we can respect independent things and have knowledge.
