Aristotle: Form and Matter

Neo-Aristotelian metaphysics comprises the topics in contemporary metaphysics which bear similarity to the interests, commitments, positions and general approaches found in Aristotle. Despite the current interest in these topics, there is no monograph length general introduction to the methodology and themes of neo-Aristotelian metaphysics. One underdiscussed question concerns demarcation: what unifies the topics that fall under the heading of neo-Aristotelianism? Contemporary metaphysicians who might be classified as ‘neo-Aristotelians’ tend towards positions reminiscent of Aristotle’s metaphysics—such as sympathy with grounding, substance ontology, (...) non-modal construals of essence, hylomorphism, causal powers, presentism, endurantism and agent causation. However, prima facie it seems that one might hold any one of these positions while rejecting the others. What perhaps unifies a neo-Aristotelian approach in metaphysics, then, is not a shared collection of positions so much as a willingness to engage with Aristotle and to view this historical figure as providing a fruitful way of initially framing certain philosophical issues. However, also missing in the literature is a sustained methodological discussion on the contribution historical scholarship on Aristotle might make to contemporary metaphysics, and the contribution contemporary metaphysics might make to historical scholarship. Little hinges on whether what gets labelled neo-Aristotelian metaphysics is or isn’t Aristotle’s metaphysics. But historical scholarship is useful within contemporary metaphysics not merely to to apply historically accurate labels to positions. There are topics where the historical and contemporary issues dovetail in mutually rewarding ways: serious engagement with the history of philosophy can yield living philosophical rewards for today’s metaphysician; and serious engagement with contemporary philosophy can yield exegetical rewards for the historian. The monograph will introduce these methodological issues, and then turn to case studies on ontological dependence, substance ontology, category theory and hylomorphism. These are all topics where there is robust debate within both Aristotle studies and contemporary metaphysics, and topics where historians and metaphysicians are working somewhat in isolation from each other. The aim of the monograph is to make the relevant exegetical questions accessible to contemporary metaphysicians, and the corresponding contemporary topics accessible to historians. The target audience includes researchers, graduate students and advanced undergraduates, in both metaphysics and Aristotle studies. (shrink)

Essentialists hold that at least a certain range of entities can be meaningfully said to have natures, essences, or essential features independently of how these entities are described, conceptualized or otherwise placed with respect to our specifically human interests, purposes or activities. Modalists about essence, on the one hand, take the position that the essential truths are a subset of the necessary truths and the essential properties of entities are included among their necessary properties. Non-modalists about essence, on the other (...) hand, oppose the reduction of essence to modality and hold, rather, that essence is more basic than, and explanatory of, modality. This chapter begins with a brief summary of Kit Fine’s well-known challenges to the modal account of essence and considers a recent attempt by “sparse modalists” like Sam Cowling and Nathan Wildman to respond to Fine’s counterexamples by adding a sparseness constraint to the “bare” modal account of essence. A further question arises, however, as to whether and how Fine’s definitional approach can avoid his own counterexamples against the modal approach to essence. The chapter concludes with some final thoughts concerning the theoretical roles ascribed to essence by modalists and non-modalists. (shrink)

If the Aristotelian division has above all an epistemic and heuristic purpose, this article aims to examine the ontological appropriation of division by Aristotle in the Metaphysics, too often neglected by secondary literature. Division is also an ontological operation, insofar it governs the relationship between the eidos (which is identified, in the context of the central books of the Metaphysics, with the primary substance, i.e. what is properly speaking), its genus and the final differentia of this genus. More precisely, we (...) will show that division is a case of the hylemorphic relation: the genus is an (intelligible) matter to which the final differentia obtained by division is predicated, and which then acts as the formal cause of this genus being such a determined eidos. However, this ontological and hylemorphic dimension of Aristotelian division is largely compatible with its methodological use. (shrink)

Aristotelian hylemorphism not only concerns the relationship between sensible matter and form, but also applies to the relationship between the 'parts' of form. By analyzing this latter case, this book aims to show the full explanatory and unifying power of hylemorphism.

In Aristotle’s account of change, lacking a form is called privation (Physics I.7 191a14). For example, someone takes on the form of being musical only from previously having the privation of being unmusical. However, he also states that “shape and nature are spoken of in two ways, for the privation too is in a way form” (Physics II.1 193b19). I will demonstrate that these seemingly contradictory statements are not actually in tension. Since all perceptible matter must be enformed, we would (...) have trouble discussing things that have yet to undergo generation, like menstrual fluid, and things that have undergone corruption, like corpses, if we did not cite the privation as a sort of form. I will argue that, given his commitment to hylomorphism, Aristotle is committed to privation being a form in a qualified sense. It cannot be a form in an unqualified sense because privation often spoils the matter such that it can no longer be reformed. The fact of the matter is we cannot draw a bright line between privation and form because the two are contraries and can be said to hold to different degrees at different points on a spectrum.

Many scholars have claimed that a well-known, allegedly ‘Rylean’ passage in DA I.4 shows that Aristotle does not think souls are subjects of mental states and activities. However, other scholars have argued against this and invoked other texts to support their rival claim that Aristotle does think souls are subjects of mental states and activities. This article articulates and defends an original interpretation of Aristotle’s position vis-à-vis this issue. In particular, this article argues that Aristotle thinks the souls of living (...) corporeal substances are ‘things that underlie’ (i.e., ὑποκɛίμɛνα for) various non-substantial features of the substances to which they belong, including whatever mental capacities those substances have. However, this does not entail that he thinks souls literally have the features they underlie, as if they themselves were alive and could engage in the kinds of mental activities (seeing, hearing, desiring, thinking, reasoning, etc.) that animals and humans can. In fact, there is good reason to think Aristotle does not think souls literally engage in such activities, despite his sometimes writing in a loose manner that suggests they do. (shrink)

Tim Ingold draws a sharp line between animism and hylomorphism, that is, between his relational ontology and a rival genealogical ontology. He argues that genealogical hylomorphism collapses under a fallacy of circularity, while his relationism does not. Yet Ingold fails to distinguish between vicious or fallacious circles, on the one hand, and virtuous or hermeneutic circles, on the other. I demonstrate that hylomorphism and Ingold’s relational animism are both virtuously circular. Hence, there is no difference between them on this count. (...) A path thus opens for what I call hylomorphic animism. While Ingold’s relational animism leads into obscurity, hylomorphic animism is able to explain the differences in power between material things.

A genus contains its species, and the species implies its genus. Does it mean that the species is a part of the genus and also the genus is a part of the species? But how can they be part of each other without being identical? In the context of kinds, in what sense is ‘part’ applicable? We argue that for Aristotle, a species and its genus are mutual parts, standing in different parthood relations to each other, viz. the genus is (...) a prior part of its species, while the species is a posterior part of its genus. Furthermore, we show that prior and posterior parthood concerning the genus and its species is grounded on the relations between matter and form in a matter-form compound. (shrink)

The place of matter in the definition of the sensible substance evolves over the course of Metaphysics books Z and H : whereas chapters 10 and 11 of book Z claim that matter must be excluded from the definiens of the sensible substance, chapter 2 of book H claims that it must include it. The present article will show that this difference in doctrine comes from a refinement of the way in which the causal priority of form is expressed in (...) the definition. First, in book Z, it is expressed by a reduction of the terms of the definiens to « parts of the form » only, a reduction which is immediately considered superfluous and unsatisfactory. In book H then, it will be by the position it occupies as a predicate of the matter that is precisely meant to express this priority. In this sense, the two sets of texts do not constitute a theoretic volte-face from Aristotle, but the refinement of a single model of definition expressing the priority of form. (shrink)

The paper investigates the distinction between form and matter in Kant’s theoretical philosophy – his adoption of an Aristotelian hylomorphism. This connection to Aristotle is sometimes recognized in Kant scholarship, though most proponents claim that against the backdrop of a structural analogy, Kant and Aristotle also differ in an important respect: according to them, while Aristotle puts forth a hylomorphic conception of being, Kant merely offers a hylomorphic conception of cognition in which sensibility provides the matter and understanding the form. (...) Against this, the paper claims that this “interiorization” of form cannot be squared with Kant’s actual views. Form is not internal for Kant, but neither is it external. Rather, it is “original form”. This interpretation ascribes a “hylomorphism all the way down” to Kant, meaning that the form and the matter of cognition are jointly actualized in virtue of each other. The understanding cannot be understood apart from its part in a hylomorphic unity with sensibility. Therefore, a proper appreciation of this unity enables us to see that it is impossible to distinguish the form that objects have as objects of cognition from the form they have in themselves.

In Latin Europe, the controversy over spontaneous generation of perfect animals – namely those whose breeding occurs through sexual reproduction – is received in different ways, varying from positions very close to Avicenna’s, as in the case of Pietro Pomponazzi, to interpretations that rather refer to Averroes’ perspective. To this ‘Averroist front’ undoubtedly belongs the figure of Urbano da Bologna, author of the Expositio commenti Averrois in VIII libros Physicorum – a work that can be defined a supercommentary to Averroes’ (...) Physica – composed in Bologna around 1334. The present study aims to provide the complete transcription of a quaestio that is present in the work – but which was disputed according to its author also in public – as an example of the elaboration of the theme of spontaneous generation in the early 14th century. The text deals with many aspects of the problem, especially elaborating on the correspondence between each specific form and its appropriate matter, in the light of the lively debates of the time, and reveals a mature understanding of Aristotle’s natural philosophy and its Averroist interpretation.

This book aims to answer two main questions about Aristotle’s theory of causality and causal explanation, especially in relation to natural science: (1) How does he answer the main philosophical questions about causes to which he thinks his predecessors’ answers are flawed? (2) How do his answers bear on the main questions we confront in thinking about causality in general? The texts that deal with causality directly are analyzed against the background of his criticisms of his predecessors and his broader (...) views about explanation, highlighting their theoretically important commitments. This allows us to reveal the conceptual architecture of his theory. The basic theory is then applied to two questions about causality, one metaphysical and one epistemological. The metaphysical question is how to account for the relation between causes and what they cause, in light of a fundamental tension between different desiderata for causal explanations. Aristotle’s answer is pluralistic: he does not think that there is one metaphysical relationship between causes and what they cause even within a given mode of causality. The epistemological question asks how we grasp causes, and grasp them in a way that yields scientific understanding. Aristotle’s answer is again a pluralist one: metaphysically different phenomena demand different cognitive resources, and some are more accessible than others. Nevertheless, there is a discernible path from simpler to more sophisticated types of cognitive grasp on causality, in such a way that Aristotle can plausibly satisfy the epistemological constraints he thinks his predecessors cannot. Aristotle thus aims to provide a non-reductionist account of causality that still leaves room for a substantive conception of understanding in natural science. (shrink)

This article expands our knowledge of the historical-philosophical process by which the dominant metaphysical account of the Christian God became ascendant. It demonstrates that Marius Victorinus proposed a peculiar model of ‘consubstantiality’ that utilised a notion of ‘existence’ indebted to the Aristotelian concept of ‘prime matter’. Victorinus employed this to argue that God is a unity composed of Father and Son. The article critically evaluates this model. It then argues that Augustine noticed one of the model's philosophical liabilities but did (...) not publicly name Victorinus when he rejected it in De Trinitate, thereby exemplifying the practice of private ‘rebuke’ (ἐλέγχɛιν).

La structure du definiens fait l’objet de deux traitements apparemment contradictoires dans les textes aristotéliciens : certains textes avancent que l’énoncé par lequel est définie une chose ne peut pas prendre la forme d’une prédication, parce que cet énoncé doit exprimer uniquement ce qu’est la chose qui est objet de la définition et non pas lui attribuer des termes, tandis que d’autres textes, notamment dans la Métaphysique, semblent suggérer précisément l’inverse, à savoir que le definiens doit prendre la forme d’une (...) prédication. Le présent article se propose de lever cette tension apparente en prolongeant la thèse de Jacques Brunschwig selon laquelle la « prédication hylémorphique », c’est-à-dire la prédication de la forme à la matière, doit être distinguée de la prédication classique. Nous montrerons que la prédication, lorsqu’elle est hylémorphique, se distingue en ce qu’elle permet d’assurer l’unité des termes qu’elle articule – matière et forme sont en effet « une seule et même chose ». Or c’est précisément là ce qui fait défaut à la prédication classique, qui attribue toujours « une chose à une autre », et c’est ce qui lui interdit donc d’être la structure du definiens. La tension entre les textes portant sur la structure prédicative ou non du definiens peut alors être levée en affirmant que le definiens est bien une prédication, qui ne peut pas être une prédication au sens standard du terme, mais qui doit être une prédication d’une forme à une matière.

In this paper I argue that both defence and criticism of the claim that humans act ‘under the guise of the good’ neglects the metaphysical roots of the theory. I begin with an overview of the theory and its modern commentators, with critics noting the apparent possibility of acting against the good, and supporters claiming that such actions are instances of error. These debates reduce the ‘guise of the good’ to a claim about intention and moral action, and in so (...) doing have become divorced from the theory's roots in classical and medieval philosophy. Aristotle and Aquinas’ ‘guise of the good’ is primarily a metaphysical claim resting on the equivalence between actuality and goodness, from which conclusions about moral action are derived. I show the reasoning behind their theory and how it forms the basis for the claims about intention and action at the centre of the modern debate. Finally, I argue that the absence of its original foundation is apparent in recent attacks on the ‘guise of the good’. It is unsurprising that modern action theory and ethics have not always been able to comfortably accommodate the ‘guise of the good’; they are only telling half of the story. (shrink)

Nos Segundos Analíticos II.8-10, Aristóteles apresenta um modelo investigativo de descoberta da essência pela causa a partir de uma estrutura triádica: a demonstração silogística. Esse modelo explanatório-causal é colocado em prática em casos de processos naturais (e.g. eclipse, trovão) e, apesar de mencionadas, as substâncias sensíveis (e.g. homem) não são concretamente analisadas – algo que só se consolida nos livros centrais da Metafísica (mais especificamente, em Z.17) a partir da análise hilemórfica. Além disso, em Segundos Analíticos II.9, Aristóteles apresenta uma (...) restrição quanto ao domínio de aplicação do modelo: apenas os itens que possuem “causa diferente” (ἕτερον αἴτιον) são passíveis de análise nesses termos. Se, por um lado, o capítulo parece ser uma restrição ao caso específico das substâncias, não são explicitados quais itens possuem e quais não possuem “causa diferente”. Desse modo, é suscitada a questão: teria Aristóteles previsto a aplicação do modelo explanatório-causal às substâncias hilemórficas quando da elaboração dos Segundos Analíticos, ou sua utilização na Metafísica representaria uma reformulação posterior? Neste cenário, temos pelo menos duas hipóteses interpretativas: (i) uma leitura restritiva (ou desenvolvimentista), em que as substâncias não teriam sido previstas; (ii) uma leitura não-restritiva, que se opõe à primeira ao defender que as substâncias já estariam previstas na elaboração dos Segundos Analíticos, e sua omissão se daria por economia argumentativa. O objetivo do presente trabalho é apresentar a hipótese não-restritiva como uma solução para o problema do ἕτερον αἴτιον, defendendo uma aproximação entre a Metafísica e os Segundos Analíticos.

William Gilbert’s 1600 book, De magnete, greatly influenced early modern natural philosophy. The book describes an impressive array of physical experiments, but it also advances a metaphysical view at odds with the soon to emerge mechanical philosophy. That view was animism. I distinguish two kinds of animism – Aristotelian and Platonic – and argue that Gilbert was an Aristotelian animist. Taking Robert Boyle as an example, I then show that early modern arguments against animism were often effective only against Platonic (...) animism. In fact, unacknowledged traces of Aristotelian animism can be found in Boyle’s mechanical account of nature. This was Gilbert’s legacy. (shrink)

This inaugural lecture, delivered on 17 November 2021 at the University of Neuchâtel, addresses the question: Are material objects analyzable into more basic constituents and, if so, what are they? It might appear that this question is more appropriately settled by empirical means as utilized in the natural sciences. For example, we learn from physics and chemistry that water is composed of H2O-molecules and that hydrogen and oxygen atoms themselves are composed of smaller parts, such as protons, which are in (...) turn composed of yet smaller parts, such as quarks, and so on. While the question at the center of this lecture might thus appear to fall more appropriately into the empirical domain of natural science, I argue that metaphysics in fact has an important role to play in determining how best to answer the question before us. More concretely, I propose that the Aristotelian doctrine of hylomorphism, when appropriately interpreted, provides the best metaphysical answer to the question of whether and how material objects are analyzable into more basic constituents. Hylomorphism holds that those entities to which this doctrine applies are, in some sense, compounds of matter (“hylē”) and form (“morphē” or “eidos”). Thus, the title of this lecture, “Form, Matter, Substance”, refers to the claim that lies at the center of the doctrine of hylomorphism, as applied to the domain of material objects, namely that sensible substances are the result of combining matter and form in the right sort of way; or, for short, “form + matter = substance”. I begin in Section II by providing some historical background which brings out Aristotle’s motivations for proposing the doctrine of hylomorphism in the context of his analysis of change. Section III turns to some of the main features of the contemporary hylomorphic theory I have defended especially in Koslicki (2008) and Koslicki (2018). Section IV discusses some challenging questions concerning artifacts which arise for both hylomorphic and other approaches to the metaphysics of concrete particular objects. Section V concludes by summarizing why, as contemporary metaphysicians, we should prefer a hylomorphic theory over its competitors as an analysis of concrete particular objects that is compatible with our current scientific understanding of the world.

In De Anima 2.4, Aristotle claims that nutritive soul encompasses two distinct biological functions: nutrition and reproduction. We challenge a pervasive interpretation which posits ‘nutrients’ as the correlative object of the nutritive capacity. Instead, the shared object of nutrition and reproduction is that which is nourished and reproduced: the ensouled body, qua ensouled. Both functions aim at preserving this object, and thus at preserving the form, life, and being of the individual organism. In each case, we show how Aristotle’s detailed (...) biological analysis supports this ontological argument. (shrink)

On the one hand, Aristotle claims that the matter of a material thing is not part of its form. On the other hand, he suggests that the proper account of a natural thing must include a specification of the kind of matter in which it is realized. There are three possible strategies for dealing with this apparent tension. First, there may be two kinds of definition, so that the definition of the form of a thing does not include any specification (...) of its matter, whereas the definition of a compound does. Second, the definition of a substance may not include a specification of its matter at all, but still reveal in what kinds of matter its form can be realized. Third, there may be a special kind of matter, functional matter, which belongs to the form of certain things. I will show that the functional matter of a thing does not belong to its form (in a strict sense of “form”), but that an adequate account of natural substances and their functions must nonetheless involve a reference to their functional matter. This means that the function of a natural thing is not the same as its form and that its adequate account as a natural thing is not a definition (in a strict sense of “form” and “definition”).

I present a developmental account of Aristotle’s concept of hê hylê (usually translated “the matter”), focused the earliest developments. I begin by analyzing fragments of some lost early works and a chapter of the Organon, texts which indicate that early in his career Aristotle had not yet begun to use he hylê in a technical sense. Next, I examine Physics II 3, a chapter in which Aristotle conceives of he hylê not as a kind of cause in its own right, (...) but merely as an example of the so-called “out of which” cause : the material is the cause out of which an artifact is made. Next, I examine Physics II 7, a chapter in which Aristotle names "the material" as one of the four kinds of cause in its own right. But Aristotle’s model of "the material" remains the material out of which an artifact is made. (shrink)

This paper evaluates six contenders which might be invoked by essentialists in order to meet Quine’s challenge, viz., to provide necessary and sufficient conditions for the crossworld identity of individuals: (i) an object’s qualitative character; (ii) matter; (iii) origins; (iv) haecceities or primitive non-qualitative thisness properties; (v) “world-indexed properties”; and (iv) individual forms. The first three candidates, I argue, fail to provide conditions that are both necessary and sufficient for the crossworld identity of individuals; the fourth and fifth criteria are (...) open to the charge that they do not succeed in meeting Quine’s demand in an explanatorily adequate fashion. On balance, then, individual forms, or so I propose, deserve to be taken very seriously as a possible response to Quine’s challenge, especially by neo-Aristotelians who are already committed to a hylomorphic conception of composite concrete particular objects for other reasons. Theorists who also accept a non-modal conception of essence, i.e., a conception according to which essence is not reducible to modality, in addition face the further difficult task, over and above what is required to meet Quine’s challenge, of having to explain how an object’s de re modal profile in some way follows from facts about its essence. Haecceities and world-indexed properties, as I indicate, are unlikely to be of much help with respect to this second challenge, while the forms of hylomorphic compounds are in fact well-suited for this purpose.

In this reply, I respond to points raised by Uwe Meixner in “Koslicki on Matter and Form” in connection with a book symposium on _Form, Matter, Substance_ held at the University of Innsbruck in May 2019.

Constitution is the relation that holds between an object and what it is made of: statues are constituted by the lumps of matter they coincide with; flags, one may think, are constituted by colored pieces of cloth; and perhaps human persons are constituted by biological organisms. Constitution is often thought to be a.

Aristotle analyses a large range of objects as composites of matter and form. But how exactly should we understand the relation between the matter and form of a composite? Some commentators have argued that forms themselves are somehow material, that is, forms are impure. Others have denied that claim and argued for the purity of forms. In this paper, I develop a new purist interpretation of Metaphysics Z.10-11, a text central to the debate, which I call 'hierarchical purism'. I argue (...) that hierarchical purism can overcome the difficulties faced by previous versions of purism as well as by impurism. Roughly, on hierarchical purism, each composite can be considered and defined in two different ways: From the perspective of metaphysics, composites are considered only insofar as they have forms and defined purely formally. From the perspective of physics, composites are considered insofar as they have forms and matter and defined with reference to both. Moreover, while the metaphysical definition is a definition in the strict sense of 'definition', the physical definition is a definition in a loose sense. Analogous points hold for intelligible composites and geometry. Finally, neither sort of definitional practice implies that, for Aristotle, forms are impure. (shrink)

In this work I propose a theory of evolution as a process of unfolding. This theory is based on four logically concatenated principles. The principle of evolutionary order establishes that the more complex cannot be generated from the simpler. The principle of origin establishes that there must be a maximum complexity that originates the others by logical deduction. Finally, the principle of unfolding and the principle of actualization guarantee the development of the evolutionary process from the simplest to the most (...) complex. These logical principles determine the existence of a virtual ideological matrix that contains the sequence of the preformed and folded morphogenetic fields. In this manner, the evolutionary process consists of the sequential unfolding and actualization of these fields, which is motorized by a process of teleologization carried out by the opening consciousness of the forms included in the fields of the ideological matrix. This theory leads to a radical change of perspective regarding the materialist worldview, and places life at the center of the evolutionary process as an activity carried out by a consciousness that seeks to fulfill a purpose by actualizing its own potentialities.

This book investigates what change is, according to Aristotle, and how it affects his conception of being. Mark Sentesy argues that change leads Aristotle to develop first-order metaphysical concepts such as matter, potency, actuality, sources of being, and the teleology of emerging things. He shows that Aristotle’s distinctive ontological claim—that being is inescapably diverse in kind—is anchored in his argument for the existence of change. -/- Aristotle may be the only thinker to have given a noncircular definition of change. When (...) he gave this definition, arguing that change is real was a losing proposition. To show that it exists, he had to rework the way philosophers understood reality. His groundbreaking analysis of change has long been interpreted through a Platonist lens, however, in which being is conceived as unchanging. Offering a comprehensive reexamination of the relationship between change and being in Aristotle, Sentesy makes an important contribution to scholarship on Aristotle, ancient philosophy, the history and philosophy of science, and metaphysics.

Aristotle presents four causes in Posterior Analytics 2.11, but where we expect matter we find instead the confusing formula, ‘what things being the case, necessarily this is the case’, and an equally confusing example. Some commentators infer that Aristotle is not referring to matter, others that he is but in a non-standard way. I argue that APo. 94a20-34 presents not matter, but determination by general features or facts, including facts about something’s genus. The closest connection to matter is Aristotle’s view (...) that the relation between genus and species is analogous to that between matter and a hylomorphic compound. (shrink)

This essay is the first part of an analysis on the form and matter in the works of Aristotle. Within the whole analysis, I shall examine passages taken from different works of Aristotle that are relevant to the investigation on form and matter. In this essay, I shall focus exclusively on the chapter Metaphysics Zeta 3. The concepts of substance, matter, ontological subject, form, composite substance, this something and separated, which are consistently used by Aristotle within the development of the (...) mentioned chapter, will be part of my survey of the contents of the chapter. The central argument of Metaphysics Zeta 3, which maintains the equivalence between substance and the feature represented by ontological subject, and which leads, through this first equivalence and through the equivalence between matter and ontological subject, to the result that matter is (the only) substance, will be investigated step by step so that all presuppositions, entailments, and consequences of the argument itself can be clearly shown. The problems which are caused by the mentioned equivalence of substance and ontological subject will be pointed out during my look at the chapter’s contents. In particular, Aristotle cannot accept that, in spite of the ontological subject being a correct feature of substance qua substance, substance is therewith reduced to matter. Being the ontological subject does not represent the only ontological feature of substance qua substance; the ontological features too of substance qua substance that are represented by being a this something and being separated belong to the concept of substance: they can never be forgotten within a right interpretation of substance. The identification of substance only with matter can never be accepted. Only the ontological values of substance represented by the form and by the composite substance possess the ontological features “being a this something” and “being separated”. Therefore, the ontological values of substance as form and as a composite substance must always be reckoned with in a correctly interpreted ontology. Neither of these values can be forgotten within an accurate inquiry of ontology. Hence, regardless of whether matter is substance and is correctly interpreted as substance, the values of substance as form and as composite substance must belong, in Aristotle’s view, to any right ontological system whatsoever. The plurality of values for substance, which I personally advocate, finds confirmation thanks to chapter Metaphysics Zeta 3: Matter, form, and composite substance all represent values for substance, despite the differences which they have as regards their own ontological features.

This paper clarifies the way Aristotle uses generation to establish the priority of activity in time and in being. It opens by examining the concept of genetic priority. The argument for priority in beinghood has two parts. The first part is a synthetic argument that accomplishment is the primary kind of source, an argument based on the structure of generation. The second part engages three critical objections to the claim that activity could be an accomplishment: activity appears to lack its (...) own structure; activity is different in kind from the object it accomplishes; and activity is external to its accomplishment. Aristotle responds to these objections by analyzing the structure of generation. In the course of the argument, Aristotle establishes that beinghood and form are activity. (shrink)

The central claim of this paper is that the Aristotelian metaphysics of objects is incompatible with physicalism. This includes the contemporary variant of Aristotelianism I call ‘sortalism’. The core reason is that an object’s identity as an instance of a (natural) kind, as well as its consequent persistence conditions, is neither physically fundamental nor determined by what is physically fundamental. The argument for the latter appeals to what is commonly known as ‘the grounding problem’; in particular I argue that the (...) physicalist has no solution, and this requires that the physicalist jettison the traditional concept of objects having kind-specific identity and persistence conditions.

In this paper, we provide an account of the ontological status of Christ’s dead body, which remained in the tomb during the three days after his crucifixion. Our account holds that Christ’s dead body – during the time between his death and resurrection – was prime matter without a substantial form. We defend this account by showing how it is metaphysically possible for prime matter to exist in actuality without substantial forms. Our argument turns on the truth of two theses: (...) God is able to produce all acts of secondary causes without those secondary causes, and Substantial forms are secondary causes of the actuality of prime matter. We argue that the metaphysical possibility of matter without form is perfectly consistent with holding both there is only one substantial form in a material substance and that prime matter is pure potentiality. Moreover, we argue that the metaphysical possibility of matter without form does little-to-no damage to our natural understanding of material substances. (shrink)

In this work, I explore and critically evaluate Aristotle’s views on the naturalness of dying from old age. His views are not straightforward, because Aristotle regards old age as a kind of decay and he talks about decay sometimes as natural and sometimes as unnatural. Nature, according to Aristotle, has two aspects, matter and form. I argue that, in Aristotle’s system, decay is always materially natural but formally unnatural. Likewise, natural death is death caused by old age and although getting (...) old is never formally natural, it is, in a particular sense, materially natural. In Aristotle’s view, getting old does not have the same mechanism as inorganic decay such as wine’s turning into vinegar, but it is a result of the materially natural decay of lungs, which leads to the exhaustion of the vital heat in the heart.

Concrete particular objects (e.g., living organisms) figure saliently in our everyday experience as well as our in our scientific theorizing about the world. A hylomorphic analysis of concrete particular objects holds that these entities are, in some sense, compounds of matter (hūlē) and form (morphē or eidos). The Grounding Problem asks why an object and its matter (e.g., a statue and the clay that constitutes it) can apparently differ with respect to certain of their properties (e.g., the clay’s ability to (...) survive being squashed, as compared to the statue’s inability to do so), even though they are otherwise so much alike. In this paper, I argue that a hylomorphic analysis of concrete particular objects, in conjunction with a non-modal conception of essence of the type encountered for example in the works of Aristotle and Kit Fine, has the resources to yield a solution to the Grounding Problem.
