Aristotle: Form and Matter

Is life a simple result of a conjunction of physico-chemical processes? Can be reduced to a mere juxtaposition of spatially determined events? What epistemology or world-view allows us to comprehend it? Aristotle built a novel philosophical system in which nature is a dynamical totality which is in constant movement. Life is a manifestation of it, and is formed and governed by the psyche. Psyche is the organizational principle of the different biological levels: nutritive, perceptive and intelective. Driesch's crucial experiment provided (...) empirical proof of the principle of life, which he called entelechy. Entelechy is an intensive manifoldness and cannot be comprehended by the usual extensive parameters. The entelechian's own ambiance is duration. This allows the reintroduction of the concept of teleology in the sphere of the living, understood not as a final cause, but as an order born from desire and leading to action. (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 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.

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.

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.

_ Source: _Volume 60, Issue 1, pp 88 - 126 The dominant interpretation of Metaphysics Θ.8 commits Aristotle to the claim that the heavenly bodies’ eternal movements are not the exercises of capacities. Against this, I argue that these movements are the result of necessarily exercised capacities. I clarify what it is for a heavenly body to possess a nature and argue that a body’s nature cannot be a final cause unless the natural body possesses capacities that are exercised for (...) the sake of its nature qua form. This discussion yields a better understanding of what capacities are, what explanatory work capacities do, and what it is to possess a nature. (shrink)

Aristotle outlines two methods in De Anima that one can employ when one investigates the soul. The first focuses on the exercises of a living organism’s vital capacities and the proper objects upon which these activities are directed. The second focuses on a living organism’s nature, its internal principle of movement and rest, and the single end for the sake of which this principle is exercised. I argue that these two methods yield importantly different, and prima facie incompatible, views about (...) what souls are. According to the first, the soul is a set of independently specifiable capacities that are related to one another in a manner that effects a unity of soul over and above the multiplicity. According to the second, the soul is a single, unitary nature that has a living organism’s form as its end. I bring the differences between these two conceptions of soul into relief and then attempt to reconcile the opposing views in a way privileges the conception according to which the soul is a unitary nature. In doing so, I discuss the following interrelated topics: (a) what makes a capacity a part of soul, (b) the relationship between the parts of soul within a given organism, (c) how a soul can be a unity while comprising various parts, (d) whether it is possible to give an adequate definition of life or soul, (e) what unity obtains among the various ways life is said that would allow for a proper, scientific investigation of life, and (f) the principle that grounds the hierarchy of souls—the nutritive, the perceptual, and the rational.

My topic is the fundamental Aristotelian division between the animate and the inanimate. In particular, I discuss the transformation that occurs when an inanimate body comes to be ensouled. When nutriment is transformed into flesh it is first changed into blood. I argue that blood is unique in being, at one and the same time, both animate and inanimate; it is inanimate nutriment in actuality (or in activity) and animate flesh in potentiality (or in capacity). I provide a detailed exposition (...) of these manners of being (covering individual substances, artifacts, and mixtures), apply these insights to the case of blood, and then argue that blood's curious status is central to understanding hylomorphism in living organisms.

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.

A review of Edward Halper's brilliant exegesis of the middle books of Aristotle's Metaphysics, in which he shows that Aristotle keys his search for the hierarchy of senses of being to his quest for the hierarchical array of the senses of unity.

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)

Aristotle’s typical procedure is to identify four causes of natural changes. Intentional action, a natural change, has standardly been treated as an exception: most think that Aristotle has the standard causalist account, according to which an intentional action is a bodily movement efficiently caused by an attitude of the appropriate sort. I show that action is not an exception to Aristotle’s typical procedure: he has the resources to specify four causes of action, and thus to articulate a powerful theory of (...) action unlike any other on offer.

Tradução dos livros Z e H da Metafísica de Aristóteles, com introdução e notas. Translation of Aristotle's Metaphysics Books VII and VIII into Portuguese, with Introduction and Notes.

This paper presents Duns Scotus’s theory of mixture in the context of medieval discussions over Aristotle’s theory of mixed bodies. It revisits the accounts of mixture given by Avicenna, Averroes, and Thomas Aquinas, before presenting Scotus’s account as a reaction to Averroes. It argues that Duns Scotus rejected the Aristotelian theory of mixture altogether and that his account went contrary to the entire Latin tradition. Scotus denies that mixts arise out of the four classical elements and he maintains that both (...) the elemental forms and the elemental qualities are lost in the mixture. Consequently, he denies the distinction between the process of mixture and that of substantial change through generation and corruption. The reassessment of Scotus’s account modifies the current historical representation of this discussion, inherited from Anneliese Maier. (shrink)

Summary of my Master's Dissertation (published in the section meant for this).

This is a comprehensive discussion of determinables, determinates, and their relation ('determination', for short), covering the historical development of these notions, the theoretical options for understanding them, and certain of their contemporary applications.

In Aristotle's cosmology, the nature of the elements is defined by their place in the Totality. Their cosmic motions keep the whole in motion, and this is their nature. Thus, the cosmos is an organized whole, a single substance directed to the good; this body constitutes together with its Prime Mover a composite substance that can be regarded as a self-mover.

Kathrin Koslicki argues that ordinary material objects like tables and motorcycles have formal proper parts that structure the material proper parts. Karen Bennett rejects a key premise in Koslicki's argument according to which the material ingredient out of which a complex material object is made is a proper part of that object. Koslicki defends this premise with a principle motivated by its power to explain three important phenomena of material composition. But these phenomena can be equally well explained by a (...) weaker principle that does not support the questioned premise in Koslicki's argument, Bennett argues. I show that Bennett's weaker principle, together with an appropriate strengthening of a different premise in Koslicki's original argument, still yields a sound argument for the existence of formal parts.

A filosofia da natureza de Aristóteles muitas vezes é apresentada como um capítulo inteiramente ultrapassado na história do pensamento: um “finalismo antiquado”, antropocêntrico, avesso à mensuração exata das condições materiais subjacentes aos fenômenos. Essa perspectiva, no entanto, é inadequada: não atenta para o papel relevante que Aristóteles atribui à matéria na explicação dos fenômenos naturais, assim como não atina com o real significado da teleologia aristotélica. Na contra-mão dessa perspectiva apressada, procuramos mostrar que, no cerne da filosofia aristotélica da natureza, (...) entendida como uma teleologia, encontra-se a idéia de que os seres naturais definem-se por uma tendência intrínseca à auto-preservação. É por essa tendência que a forma de cada ser natural governa teleologicamente sua matéria. (shrink)

In a difficult but fascinating passage in Metaphysics Z.17, Aristotle puts forward a proposal, by means of a regress argument, according to which a whole or matter/form-compound is one or unified, in contrast to a heap, due to the presence of form or essence. This proposal gives rise to two central questions: (i) the question of whether form itself is to be viewed, literally and strictly speaking, as part of the matter/form-compound; and (ii) the question of whether form is to (...) be regarded as itself having parts. It is argued that both questions may be answered affirmatively, without giving rise to a regress worry. (shrink)

I will argue that Aristotle’s fourfold division of four causes naturally arises from a combination of two distinctions (a) between things and changes, and (b) between that which potentially is something and what it potentially is. Within this scheme, what is usually called the “efficient cause” is something that potentially is a certain natural change, and the “final cause” is, at least in a basic sense, what the efficient cause potentially is. I will further argue that the essences of things (...) and changes are not features or attributes of them, but paradigms that set the standards according to which these things and changes may be judged to be natural or typical. The “formal cause” of a natural thing will be shown to be its essence in this sense: it sets the standards of typicality that apply to instances of its kind. The final cause will be shown to set the standard of typicality for natural changes. When we understand Aristotle’s doctrine of the four causes in this way, it becomes clear on what basis he could convincingly argue that final causality is operative in the whole of nature. (shrink)

In various texts, Aristotle assigns priority to form, in its role as a principle and cause, over matter and the matter-form compound. Given the central role played by this claim in Aristotle's search for primary substance in the Metaphysics, it is important to understand what motivates him in locating the primary causal responsibility for a thing's being what it is with the form, rather than the matter. According to Met. Theta.8, actuality [ energeia / entelecheia ] in general is prior (...) to potentiality [ dunamis ] in three ways, viz., in definition, time and substance. I propose an explicitly causal reading of this general priority claim, as it pertains to the matter-form relationship. The priority of form over matter in definition, time and substance, in my view, is best explained by appeal to the role of form as the formal, efficient and final cause of the matter-form compound, respectively, while the posteriority of matter to form according to all three notions of priority is most plausibly accounted for by the fact that the causal contribution of matter is limited to its role as material cause. When approached from this angle, the work of Met. Theta.8 can be seen to lend direct support to the more specific and explicitly causal priority claim we encounter in Met. Z.17, viz., that form is prior to matter in its role as the principle and primary cause of a matter-form compound's being what it is. (shrink)

The first major work in the history of philosophy to bear the title "Metaphysics" was the treatise by Aristotle that we have come to know by that name. But Aristotle himself did not use that title or even describe his field of study as 'metaphysics'; the name was evidently coined by the first century C.E. editor who assembled the treatise we know as Aristotle's Metaphysics out of various smaller selections of Aristotle's works. The title 'metaphysics' -- literally, 'after the Physics' (...) -- very likely indicated the place the topics discussed therein were intended to occupy in the philosophical curriculum. They were to be studied after the treatises dealing with nature (ta phusika). In this entry, we discuss the ideas that are developed in Aristotle's treatise. (shrink)

Commentary on Aristotle's Metaphysics Lambda. It accompanies the translation of Aristotle's Metaphysics Lambda into Portuguese in the same volume of the journal.

This special issue centers around Aristotelian metaphysics, construed broadly to cover both scholarly research on Aristotle’s metaphysics, as well as work by contemporary metaphysicians on Aristotelian themes. It focuses on two themes in Aristotelian metaphysics, namely essence and grounding, and their connections. A variety of related questions regarding dependence, priority, fundamentality, explanation, causation, substance, and modality also receive attention.

John McCumbers’ book On Philosophy: Notes from a Crisis challenges the key dichotomy of Western philosophical tradition— the distinction between form, or οὐσία, and matter. This basic ontological distinction, first formulated by Aristotle, appears under different guises throughout the history of Western thought, making oppression integral to philosophy, and leading the discipline into the situation of a major crisis, in which, as McCumber eloquently argues, philosophy and philosophers find themselves today. In this essay I argue that by developing the notion (...) of the speaking of matter McCumber subverts the oppressive history of Western philosophy. I explore this rich concept, showing how it successfully undermines ousiodic ontology. By drawing on McCumber’s text, and also on the works of Gilles Deleuze and Gloria Anzaldúa I argue that a non-ousiodic ontology has to prioritize anomalous, or seemingly contradictory beings. I discuss one possible direction such ontology could take—it could focus on the internal stranger, or the metic, to use an ancient Greek term. (shrink)

The Role of Negation in the Description of the World According to Aristote’s Metaphysics. The notions of ‘being’ and ‘non-being’ have entered philosophical language, forming the basis of ontology and meontology, as the counterparts of the Greek expressions to on and to me on (nominalised forms, affirmative and negative, of the participle of the verb einai). Originally, however, these expressions did not have any objectifying meaning, but played the role of meta-language names, representing the copula einai in all its forms, (...) most generally in its affirmative and negative forms. The copula itself, which in later philosophy took on the existential meaning, had functioned only as a semantically empty connective of predicates. Over time the participle on has been used as a universal name of all predicates. The above-mentioned expressions became central in Greek philosophical terminology thanks to the debates, initiated by Parmenides, on the role of negation in the description of the world. Parmenides himself proposed a complete excision of negative sentences as describing by elimination, and created a positive-monistic system which abandoned multiplicity, divisibility, and variability. Later philosophers defended negation, fighting back against the paradoxes formulated by the Eleatics and later by the Sophists. Plato observed that without negation it is impossible to describe the multiplicity of things. He also distinguished a relative negation which does not eliminate anything but makes it possible to confront some things with others. According to the atomists, the divisibility of physical things forces us to accept that they consist of a positive element in the form of an impenetrable body, and of another element lacking any characteristics, i.e. the void. Finally, Aristotle, when analysing the process of change, justified the consistency of the statement that something comes out of “not being” and “being”, under the assumption that the former is understood as being actual, and the latter as being potential. In all these conceptions there is nothing non-existent, there are only proposals of how to identify the aspects of reality whose explanation justifies the use of negation. The affirmative and negative forms of the above expressions have also provoked reflection on the problem of truth and falsity. It has been observed that they are used in everyday language not only to state an agreement or disagreement with the actual facts of the matter, but also to affirm or deny something. (shrink)

I have two aims in this paper. First, I argue that, in Aristotle’s theory of the four causes, there is a basic and common feature by which all causes are causes: they all work in a triadic framework in which they explain why a given attribute holds of a given underlying thing. Secondly, I argue against a version of “compatibilism” according to which each kind of cause is complete in its own domain and does not compete with any other kind. (...) I claim that there are priority relations according to which some kinds of cause are subordinated to others, even if these relations do not hold in every cases. (shrink)

THE most influential figure in Aristotelian scholarship in modern times was undoubtedly Werner Jaeger. There had been great original thinkers about Aristotle in the hundred years before Jaeger: one need only mention Brandis in Germany and Case in England. There were also fine scholars contemporary with Jaeger, like Sir David Ross, the editor and commentator on Aristotle. But no Aristotelian scholar made such an impact as Jaeger. His arguments for Aristotle’s development, for his declining Platonism and growing empiricism, started a (...) sort of revolution in Aristotelian studies. Jaeger’s position has been very much questioned since but it would be ungenerous to call his work on Aristotle anything other than a great contribution to scholarship. But Jaeger did not attempt an extended analysis and criticism of central problems in Aristotle’s philosophy. And the same must be said of other prominent contributors to Aristotelian scholarship in this century. Ross’s editions and commentaries on Aristotle are invaluable but his commentary often seems to leave off just when the problem is getting interesting. This may be explained by his reported answer to the question of whether he actually agreed with Aristotle: ‘Oh, my dear child, I am a scholar, not a philosopher’. This might not be the answer of Ingemar During who has written the latest big scholarly book covering all aspects of Aristotle’s thought but one feels at times that it should be, and particularly when Düring is dealing with Aristotle’s metaphysics.

Doing and Being confronts the problem of how to understand two central concepts of Aristotle's philosophy: energeia and dunamis.

The paper examines the connection between Aristotle's theory of generated substance and his notion of potentiality in "Metaphysics" Θ.7. Aristotle insists that the matter of a substance is not what that substance is, against a competing view that was widely held both in his day and now. He coined the term thaten (ἐ[unrepresentable symbol]νινονον) in order to make this point. The term highlights a systematic correspondence between the metaphysics of matter and of quality: the relationship between a thing and its (...) matter is like the relationship between a qualified thing and the relevant quality. It is argued that Aristotle's view about the matter of particular substances is connected with his view about ultimate matter. His conception of the matter of particular substances allows him to block an argument, from Plato's "Timaeus", that ultimate matter must be something imperceptible and lacking all perceptible qualities. Aristotle uses the term thaten to introduce an alternative conception of ultimate matter on which ultimate matter might well be an ordinary perceptible kind of thing. (shrink)

This study shows that Aristotle’s introduction of the concept of substance represents a caesura in the history of ontology. The study takes two values for substance into consideration, which are a) substance as an organism (as a biological entity) and b) substance as essence, nature, form of an organism. Substances as organisms are biological concretized properties. Substance as form is the soul directing the organism and the development of the organism; the soul is both the principle of life of the (...) organism and the program which is realized in the organism. The substance as an organism is assigned the central position in Aristotle’s ontology: the organism is not reduced to forces or factors which should have an ontological primacy over the organism; the principle of life and activity of every organism is put into the biological entity and it is not identified with factors that lie outside the organism. (shrink)

The study deals with the main aspects of substance in the works of Aristotle. The presence of a plurality of values for substance is the central idea of the study; in particular, substance has 1) the value of living biological entity and 2) the value of form of the biological entity; both values are fundamental components of Aristotle's theory of substance. The prevalence, in the works of Aristotle, of the first or of the second of the two values depends on (...) the prevailing research interest of Aristotle in each work. The idea of a continuity in Aristotle's interpretation of substance in Aristotle's works is endorsed. This research treats, moreover, of the role of form as actuality, of the relations between form and matter in the material entities, and of the problem of the unity of definition. (shrink)
