I discuss Aristotle's treatment of essence and definition in Metaphysics VII.4. I argue that it is coherent and perfectly in accord with its broader context. His discussion in VII.4 offers, on the one hand, minimal criteria for what counts as definition and essence for whatever kind of object, but also, on the other hand, stronger criteria for a primary sort of definition and essence—and thereby it serves the interest of book VII in pointing to the explanatory power of the essence (...) of composite substances.

According to Aristotle, the medical art aims at health, which is a virtue of the body, and does so in an unlimited way. Consequently, medicine does not determine the extent to which health should be pursued, and “mental health” falls under medicine only via pros hen predication. Because medicine is inherently oriented to its end, it produces health in accordance with its nature and disease contrary to its nature—even when disease is good for the patient. Aristotle’s politician understands that this (...) inherent orientation can be systematically distorted, and so would see the need for something like the Hippocratic Oath. (shrink)

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.

La exposición y crítica de las doctrinas antiguas tiene un lugar importante en los escritos de Aristóteles. Sin embargo, ciertas dudas se han vuelto corrientes acerca de la confiabilidad de sus descripciones. Más aún, se ha sostenido que Aristóteles deforma la comprensión histórica a través de la introducción de conceptos y términos propios. En este libro se aborda el problema a través de un análisis de las críticas que Aristóteles dirige a la teoría platónica de las Ideas, que permite explicar (...) la constitución y desarrollo de importantes conceptos aristotélicos a partir de la confrontación dialéctica con las doctrinas de su maestro. En efecto, las dificultades genuinas que Aristóteles descubre en el platonismo constituyen el motor para gestar nuevos conceptos, que no son ajenos, sino que surgen como implicaciones del examen crítico. Así, la imposición de términos propios no debe interpretarse como distorsión, sino como el modo que Aristóteles adopta para exhibir su particular solución a los problemas que los filósofos anteriores dejaron sin solución.

This paper focuses on two passages of Aristotle’s Metaphysics, one in Z 3, the other in H1, in which Aristotle seems to assert that the hupokeimenon is said in three ways, as matter, form, and the compound of matter and form. From these two passages it is often said that subjecthood is a criterion for being substance. A consequence of this is that, if form is to be substance, and form is substance, namely first substance, it has to comply with (...) the subject-criterion. This paper challenges this reading, purporting to show that these two passages need not commit Aristotle to the subject-criterion, and that there are good reasons not to commit him to it. (shrink)

The reflections recorded in this paper arise from three moments in the theory of definition and of conceptual analysis. The moments are: Frege’s review of Husserl’s Philosophy of Arithmetic, the discussion there of the paradox of analysis, and the division that Frege marks, ensuing upon his distinction of Sinn/sense from Bedeutung/reference, between two different conceptions of definition; Leibniz’s still serviceable account of a distinction between the clarity and the distinctness of ideas---a distinction that prompts the suggestion that the guiding purpose (...) of lexical definition is Leibnizian clarity whereas that of real definition is inseparable from the pursuit of Leibnizian distinctness; Leibniz’s speculations concerning the limit or terminus of analysis. The apparent failure of these speculations, casting doubt as it does upon the aspirations that give rise to them, points to the long-standing need to reconfigure the philosophical business of enquiry into concepts.

When Aristotle argues at the Metaphysics Z.17, 1041b11–33 that a whole, which is not a heap, contains ‘something else’, i.e. the form, besides the elements, it is not clear whether or not the form is a proper part of the whole. I defend the claim that the form is not a proper part within the context of the relevant passage, since the whole is divided into elements, not into elements and the form. Different divisions determine different senses of ‘part’, and (...) thus the form is not a part in the same sense as the elements are parts. I object to Koslicki’s (2006) interpretation, according to which the form is a proper part along the elements in a single sense of ‘part’, although she insists that the form and the elements belong to different categories. I argue that Koslicki’s reading involves a category mistake, i.e. the conjunction of items that do not belong to the same category (Goldwater 2018). Since for Aristotle parthood presupposes some kind of similarity of parts, the conjunction of form and elements requires treating these items as somehow belonging to the same category, e.g. ‘being’, but no such category exists.

In Categories 7, Aristotle gives two different accounts of relatives, and presents the principle of cognitive symmetry, which seems to help distinguish between relatives and some secondary substances. I suggest that the long-disputed difference between the two accounts lies in a difference in the determination of the categorial status of the object in question, and I formulate the principle of cognitive symmetry such that it plays a crucial role in making explicit how one conceptualizes the categorial status of the object. (...) I then set out some consequences following from this understanding for certain interpretive issues, such as the unity of the Categories. (shrink)

This paper presents a reading of Metaphysics Z.10–11 according to which both chapters outline two main definienda: forms and material substances or compounds, each of which is governed by its own peculiar constraints. Forms include formal parts alone; furthermore, they are the main definable items and enjoy the strictest possible unity. However, this does not preclude Aristotle from upgrading material compounds to the status of definable items in their own right. Z.10 explains this contention by making the compound’s sensible functional (...) matter dependent on its form. This dependence affords the resulting compound an unusually tight form-matter relationship, strong enough to ensure its definability, despite falling short of the highest kind of unity that only forms display. (shrink)

Aristotle’s main thesis in Metaphysics Z.17, which takes substance to be a principle and a cause of some sort (1041a9–10, 1041b7–9, b30–31), is of a piece with the assumption that hylomorphic compounds are unified wholes (1041b11–12) – an assumption that proves critical to settling an important controversy about the form-matter relationship in that chapter, i. e. whether matter and form are mutually indistinguishable or rather just accidentally the same. By rejecting these interpretive options, this paper argues that form and matter (...) are bound together by an essential link which, nevertheless, is able to preserve both (i) the different explanatory roles that each of those principles play vis-à-vis specific substances and (ii) the compound’s proper unity.

This chapter contains sections titled: Some Metaphysical Preliminaries The Introduction of Matter and Form The Hierarchy of Form and Matter Matter and Potentiality, Form and Actuality; the Teleological Conception of Matter Form, Matter, and the “Unity of Substance” Prime Matter Entrapment and the Homonymy of the Body and Its Organs Note Bibliography.

This paper argues that Aristotle’s Metaphysics Z.3 deploys a reductio against the claim that ‘substances underlie by being the subjects of predication’, in order to demonstrate the need for a new explanation of how substances underlie. Z.13 and H.1 corroborate this reading: both allude to an argument originally contained in Z.3, but now lost from our text, that form, matter and compound ‘underlie’ in different ways. This helps explain some of Z’s peculiarities—and it avoids committing Aristotle to self-contradiction about whether (...) matter is substance, a claim denied in the reductio but endorsed elsewhere.

The list of katēgoriai presented at the start of Top. I 9 was traditionally interpreted as a version of the canonical Aristotelian list of categories, and as largely equivalent to the list we find in Categories 4. Accordingly, its first item, the ‘what it is’, was identified with the category of substance. This interpretation has been challenged by several scholars, all sharing the view that the ‘what it is’ in Top. I 9 cannot be substance, since it collects items belonging (...) to all Aristotelian categories (e. g. human being, colour, length). Rather, they say, it is a manner of predication – i. e. essential predication – and can only determine an ontologically miscellaneous class of items. Against this family of proposals, I argue afresh that the traditional interpretation is almost entirely correct. To this purpose, I take advantage of the distinction between kinds of predicate and kinds of predication. (shrink)

This article aims at elucidating the logic of Arist. SE 22, 178b36–179a10 and, in particular, of the sophism labelled "Third Man" discussed in it. I suggest that neither the sophistic Walking Man argument, proposed by ancient commentators, nor the Aristotelian Third Man of the , suggested by modern interpreters, can be identified with the fallacious argument Aristotle presents and solves in the passage. I propose an alternative reconstruction of the Third Man sophism and argue that an explanation of the lines (...) regarding the identity of Coriscus and Coriscus the musician (178b39–179a3) is indispensable for its correct understanding, since they hint at another sophism in some important aspects analogous. Finally, I show that two contradictions concerning spotted by scholars in the passage are only apparent and can be dissolved once the assumption that the anti-Platonic Third Man argument is at stake here is discarded, and once the passage is read in the light of its agonistic context.

I use Plotinus to present absolute divine simplicity as the consequence of principles about metaphysical and explanatory priority to which most theists are already committed. I employ Phil Corkum’s account of ontological independence as independent status to present a new interpretation of Plotinus on the dependence of everything on the One. On this reading, if something else (whether an internal part or something external) makes you what you are, then you are ontologically dependent on it. I show that this account (...) supports Plotinus’s claim that any entity with parts cannot be fully independent. In particular, I lay out Plotinus’s case for thinking that even a divine self-understanding intellect cannot be fully independent. I then argue that a weaker version of simplicity is not enough for the theist since priority monism meets the conditions of a moderate version of ontological independence just as well as a transcendent but complex ultimate being.

This is a survey of Aristotle's development of the concept of substance in the Categories and Book VII (Zeta) of the Metaphysics. We begin with the Categories conception of a primary substance as that which is not "in a subject" -- i.e., not ontologically dependent on anything else -- and also not "said of a subject" -- i.e., not predicated of any item beneath it in its categorial tree. This gives us the idea of primary substances as ontologically basic individuals, (...) the fundamental subjects of predication and of change. We then examine the conception of substance in Metaphysics Zeta, where Aristotle is interested not just in the question of what the primary substances are, but in the question of what makes them substances, or, as he would put it, what the "substance OF something" is. The conception of substance that Aristotle ends up with seems (as has been frequently noted) to be threatened with inconsistency, in that Aristotle seems to want to maintain, simultaneously, that (i) substance is form, (ii) form is universal, and (iii) no universal is a substance. Two main approaches toward resolving this inconsistency are considered, and a sketch is provided of how one of these approaches might be fleshed out. On the line I propose, the substantial form of a material compound is predicated accidentally and universally of the matter of that compound, but it is not the substance of the matter of which it is predicated. Rather, it is the substance of itself; but since it is the cause of the compound's being essentially the kind of thing that it is, the substantial form is, in a derivative way, the substance of the compound as well.

Aristotle's account of external goods in Nicomachean Ethics I 8-12 is often thought to amend his narrow claim that happiness is virtuous activity. I argue, to the contrary, that on Aristotle's account, external goods are necessary for happiness only because they are necessary for virtuous activity. My case innovates in three main respects: I offer a new map of EN I 8-12; I identify two mechanisms to explain why virtuous activity requires external goods, including a psychological need for external goods; (...) and I show the relevance of Aristotle's distinction between wishing and choosing. On the view I attribute to Aristotle, our capacity to choose virtuously requires, first, that we wish for external goods (because virtue requires the right attitudes of evaluation) and, second, that these wishes are generally fulfilled (because the social consequences and psychological pain of unfulfilled wishes undermine our opportunity to act virtuously and to take pleasure in acting virtuously). I close with discussion of how Aristotelians should defend this approach. (shrink)

This book discusses Aristotle’s notions of essence and substance as they are developed in Metaphysics ZH. I examine Aristotle's argument at length and defends an unorthodox interpretation according to which his motivation is to provide an answer against a conflation between criteria for existential priority (delivering substances as primary beings) and criteria for explanatory priority (delivering essences as primary principles).

Through a detailed analysis of the various modes of argumentation employed by Aristotle throughout his natural scientific works, I aim to contribute to the growing scholarship on the relation between Aristotle’s theory of science and his actual scientific practice. I challenge the standard reading of Aristotle as a methodological empiricist and show that he permits a variety of non-empirical arguments to support controversial theses in properly scientific contexts. Specifically, I examine his use of logical (logikôs) argumentation in the discussion of (...) mule sterility in Generation of Animals II 8, rational (kata ton logon) argumentation in his discussion of cardiocentrism throughout the biological works, and the method of division in Posterior Analytics II 13.

I discuss Aristotle’s views in Metaphysics VII-6 (Z-6) on the issue whether each thing is the same as its essence. I propose a deflationary interpretation according to which Z-6 develops a “logical approach” (logikos) in which “sameness” amounts only to coextensiveness between definiendum and definiens with no attention to more specific issues about ontological and explanatory features of definitions.

Me propongo explicar que los términos sustanciales usados individuadoramente constituyen la expresión lingüística que fija la referencia a un objeto en el Organon de Aristóteles, y mostrar que esa expresión opera allí como principium individuationis. El artículo desarrolla dos tesis principales: Es legítimo adjudicar a Aristóteles una teoría descriptiva de la referencia, en la cual las propiedades esenciales incluidas en la definición constituyen condiciones suficientes para referir, dado un contexto donde los términos sustanciales se usan para individuar. Los individuos sustanciales (...) se ubican justificadamente en la base ontológica de las Categorías en virtud de que son los objetos de la referencia, y también de que se desempeñan como sujetos últimos de la predicación. My main goal is to explain that the substantial terms fix the reference to an object, and to show that this expression is the principium individuationis, within the Aristotelian Organon. The paper works out two main theses: Aristotle may be ascribed a descriptive theory of reference in which the essential properties included in the definition constitute sufficient conditions for referring to an object, provided that in the context the substantial terms are used to individualize. Substantial individuals are justifiably included at the bottom of the ontology in the Categories by virtue of their being the objects of reference, and also by virtue of their role as ultimate subjects of predication.

This paper explores the various ways Aristotle refers to and employs “heat and cold” in his embryology. In my view, scholars are too quick to assume that references to heat and cold are references to matter or an animal’s material nature. More commonly, I argue, Aristotle refers to heat and cold as the “tools” of soul. As I understand it, Aristotle is thinking of heat and cold in many contexts as auxiliary causes by which soul activities (primarily “concoction”) are carried (...) out. This, as I argue, is what it means to call them “tools” of soul. An upshot of this investigation is the fuller picture of Aristotle’s conception of efficient causation it provides in general, and the better understanding of the efficient causal operation of an organism’s nature or soul it provides in particular.

The nature and value of autonomy has long been debated in diverse philosophical traditions, including moral and political philosophy. Although the notion dates back to ancient Greek philosophy, it was during the Age of Enlightenment that autonomy drew much attention. Thus, as may be known, moral philosophers tended to emphasize self-regulation, particularly one’s own will to abide by universal moral laws, as the term “autonomy” originates from the Greek words “self” (auto) and “rule” (nomos). In parallel, modern epistemologists supposedly espoused (...) the idea of intellectual autonomy as self-reliance. In this classical view, an intellectually autonomous explorer of knowledge must not depend on a belief that is obtained from another’s testimony, until one can justify it to oneself. However, accompanying the growing focus on the importance of social dimensions of acquiring knowledge and understanding, recent epistemologists have doubted the classical view and have since reconsidered intellectual autonomy from distinct approaches such as social and virtue epistemology. This paper propounds an interpersonal-epistemic approach to intellectual autonomy. First, it is argued that thinking through questioning both individually and with other epistemic peers is an interpersonal-epistemic practice. Second, it is demonstrated that with particular cognitive features inherent within us, an intellectually autonomous person must think through questioning in necessary situations. This interpersonal account of intellectual autonomy can conceptually enrich intellectual autonomy by considering its relationship with not only responsibility but also with vulnerability. Specifically, regarding responsibility, an intellectually autonomous person must be responsible for his or her own actions throughout questioning processes. Regarding vulnerability, our intellectual autonomy lies in retaining autonomy with vulnerability in the plastic control of the questioning processes. (shrink)

In Metaphysics Z.6, Aristotle argues that each substance is the same as its essence. In this paper, I defend an identity reading of that claim. First, I provide a general argument for the identity reading, based on Aristotle’s account of sameness in number and identity. Second, I respond to the recent charge that the identity reading is incoherent, by arguing that the claim in Z.6 is restricted to primary substances and hence to forms.

The particular subject of this article is the very first sentence of Aristotle’s Metaphysics book Lambda: what does it really mean? I would stick to the most generous sense: (Aristotelian) theoria is about substance. Indeed, it has been often held that Lambda ignores the so-called focal meaning, and shows a remarkably rough stage of Aristotle’s conception of prime philosophy. By contrast, in this light, the very incipit of Lambda appears to testify Aristotle’s concern in an ontological foundation of theoretical wisdom (...) as such, which Lambda shares with the Metaphysics “central books”, Zeta in particular, in a not less coherent and possibly more advanced form.
