The relation of ontological dependence or grounding, expressed by the terminology of separation and priority in substance, plays a central role in Aristotle’s Categories, Metaphysics, De Anima and elsewhere. The article discusses three current interpretations of this terminology. These are drawn along the lines of, respectively, modal-existential ontological dependence, essential ontological dependence, and grounding or metaphysical explanation. I provide an opinionated introduction to the topic, raising the main interpretative questions, laying out a few of the exegetical and philosophical options that (...) influence one’s reading, and locating questions of Aristotle scholarship within the discussion of ontological dependence and grounding in contemporary metaphysics.

Both literalism, the view that mathematical objects simply exist in the empirical world, and fictionalism, the view that mathematical objects do not exist but are rather harmless fictions, have been both ascribed to Aristotle. The ascription of literalism to Aristotle, however, commits Aristotle to the unattractive view that mathematics studies but a small fragment of the physical world; and there is evidence that Aristotle would deny the literalist position that mathematical objects are perceivable. The ascription of fictionalism also faces a (...) difficult challenge: there is evidence that Aristotle would deny the fictionalist position that mathematics is false. I argue that, in Aristotle's view, the fiction of mathematics is not to treat what does not exist as if existing but to treat mathematical objects with an ontological status they lack. This form of fictionalism is consistent with holding that mathematics is true. (shrink)

This article analyses the Plotinian reconsideration of the link between the definition of happiness and the homonymy of life. To safeguard Platonism, Plotinus inverts the Aristotelian discussions of homonymy and its metaphysical implications, and presents the prior-posterior relationship in terms of progressive degradation. Happiness does not consist of “life” in general nor of the “rational life” ; rather, it consists of the life that is situated in the ontologically first and most perfect degree, which is the life that pertains to (...) intelligence and is consubstantial with it, and of which the other lives are progressively degraded derivations. The man who possesses the first and perfect life of the intelligible in actuality, like the gods, can be considered happy. (shrink)

On the basis of careful textual exegesis and philosophical analysis, and contrary to the received view, Mark R. Wheeler demonstrates that Aristotle presents and systematically explicates his definition of the essence of the truth in the Metaphysics. Aristotle states the nominal definitions of the terms "truth" and "falsehood" as part of his arguments in defense of the logical axioms. These nominal definitions express conceptions of truth and falsehood his philosophical opponents would have recognized and accepted in the context of dialectical (...) argument. On the basis of these nominal definitions, Aristotle develops his definitions of the essences of truth and falsehood--his "real" definitions of truth and falsehood. Aristotle's methodical exposition of his essential definitions of truth and falsehood in the Metaphysics serves as a well-developed example of how his philosophical inquiry starts with nominal definitions and ends with real definitions. Wheeler also argues for the novel claim that Aristotle defines the most fundamental kind of truth in terms of accurate measurement. Aristotle's metrical conception of truth serves as the theoretical basis for specifying the truth conditions of various assertions, for identifying the sorts of beings implicated in these truth conditions, and for explaining the nature of approximate truth and falsehood. Far from offering us a minimal account of truth, Wheeler shows how Aristotle offers us a sophisticated and metrical theory of truth. (shrink)

Translation of Aristotle's Metaphysics IV and VI, with notes. The translation is preliminary and intended as a provisional teaching tool to be also used in seminars and discussions with peers in order to reach a more elaborated version.

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.

Translation of Aristotle's Metaphysics I-III into Portuguese, with a few notes and introduction. The translation, which was made at 2007, is preliminary and its publication was intended to provide a didactic tool for courses as well as a provisional resource in research seminars. It needs some revision. I am currently working (slowly...) on the revision of the translation and a new revised one will surely appear at some point.

The notion of homonymy has been of perennial philosophical interest to scholars of Aristotle from ancient Greek commentators to modern thinkers. Across historical periods, certain issues have remained central, such as the nature of Aristotelian homonymy, its relation to synonymy and analogy, and whether the concept undergoes change throughout the corpus. In addition, fundamental questions concerning the use of homonymy in regard to dialectical practice and scientific inquiry are raised and discussed. It is argued that there are two aspects to (...) Aristotelian homonymy, negative and positive in function, which provide complementary roles in regard to dialectic and science. (shrink)

This paper presents evidence that ‘because’ is importantly ambiguous between two closely related senses covering what are usually called causal explanations, on the one hand, and grounding or metaphysical explanations, on the other hand. To this end, it introduces the lexical categories of monosemy, polysemy and homonymy; describes a test for polysemy; and discusses the results of the test when applied to ‘because’. It also shows how to understand so-called hybrid explanations in light of the semantic facts established by the (...) analysis. (shrink)

Aristotle holds that individual substances are ontologically independent from nonsubstances and universal substances but that non-substances and universal substances are ontologically dependent on substances. There is then an asymmetry between individual substances and other kinds of beings with respect to ontological dependence. Under what could plausibly be called the standard interpretation, the ontological independence ascribed to individual substances and denied of non-substances and universal substances is a capacity for independent existence. There is, however, a tension between this interpretation and the (...) asymmetry between individual substances and the other kinds of entities with respect to ontological independence. I will propose an alternative interpretation: to weaken the relevant notion of ontological independence from a capacity for independent existence to the independent possession of a certain ontological status.

La “relación” en Tomás de Aquino es una de las “categorías” aristotélicas que representan “accidentes”. No obstante, tal compromiso metafísico conlleva algunas dificultades ya que el esquema “sustancia”-“accidentes” no deja lugar a la idea de un “término medio” entre dos cosas. En este artículo presento algunas tensiones entre la sistematización de la “relación” como categoría en Tomás de Aquino y su posición sobre el “estatus” de los predicamentos en general. Para ello analizo primero la deducción de las categorías tal como (...) es presentada por el autor para luego abordar la “relación” de modo sistemático. En esta exposición argumento que Tomás tiene severas dificultades para asignarle un “fundamento accidental propio” distinto al de los otros predicamentos que le permita considerarla una de las “categorías”.

This paper examines Aristotle’s argument in Eudemian Ethics 1.8 that eudaimonia, the best practicable good, is the telos of the practicable goods. Aristotle defers to the Platonists in thinking that the best practicable good is the first practicable good and the cause of the other practicable goods’ goodness. But, on his view, it is the telos of the practicable goods that has these two properties. Aristotle’s argument for this latter claim is supported by his view, more fully discussed in Posterior (...) Analytics 2.11, of how final causes explain normative facts. (shrink)

This study investigates the problem of the natural universal in the works of Mullā Ṣadrā. The problem of universals made its way into Arabic/Islamic philosophy via its Greek sources, and was transformed into the problem of natural universals by Avicenna. Weighing in on this problem, Ṣadrā reinterprets the nature of natural universals against the backdrop of his doctrine of “the primacy of being.” As he argues, a natural universal or quiddity qua quiddity is an “accidental being” that requireswujūdfor its existentiation. (...) Thus, Ṣadrā re-envisions the status of natural universals by stripping them of their disputed status as independently existing entities.RésuméDans cette étude je me propose de réfléchir sur le problème de l'universel naturel dans l’œuvre de Mullā Ṣadrā. Le problème des universaux s'est introduit dans la philosophie arabe et musulmaneviales sources grecques et s'est trouvé transformé en celui des “universaux naturels” aux mains d'Avicenne. En contribuant à son tour à l’évolution de ce problème, Ṣadrā réinterpréta le statut des universaux naturels à partir de sa propre doctrine de la “primauté de l’être”. Selon lui, un universel naturel ou “quiddité en tant que quiddité” est un “être par accident” qui requiertwujūdpour son existentiation. Ainsi, Ṣadrā re-envisage le statut des universaux naturels en les privant de leur statut contesté en tant qu'entités “indépendantes existantes”. (shrink)

This paper discusses Aristotle’s account of multivocity as expounded in Topics 1.15. This article argues that an inquiry into how many ways something is said becomes for Aristotle a tool of dialectical examination that he employs throughout his entire philosophical career: investigating the many/multiple ways something is said allows one to recognize the ambiguity of the term in question and, consequently, to construct an adequate definition of its referent. The present study reconstructs the various strategies for detecting ambiguity and discusses (...) its different types. Subsequently, the paper accounts for why Aristotle moves so easily from words and their meanings to things and their essences. Finally, the article presents an analysis of the connection between the many ways something is said and the various categories it is predicated in. The considerations are supported by a new translation of Topics 1.15. (shrink)

Aristotle's criticism of Platonic Forms in the Metaphysics has been a major source for the understanding and developments of the theory of Forms in later Antiquity. One of the cases in point is Aristotle's argument, in Metaphysics I 9, 990b22-991a2, against Forms of non-substances. In this paper, I will first provide a careful analysis of this passage. Next, I will discuss how the argument has been interpreted - and refuted - by the fifth-century Neoplatonists Syrianus and Proclus. This interpretation has (...) played an important role in the broader context of the Neoplatonic debates on the range of Plato's theory of Forms, which was one of the traditional problems discussed about the Forms in later Platonism.

This doctoral thesis addresses a group of conceptual instruments that are central to Aristotle's philosophy, namely, the concepts of pros hen, homonymy, synonymy and multivocity. These instruments are crucial to many of Aristotle's works as he devotes himself to analysing the key notions in each of his investigations using these instruments. Despite the undisputable importance of these instruments, they display severe interpretative problems, which this thesis critically evaluates. The currently established view on the relationship between homonymy and multivocity is discussed (...) and then reassessed in order to approach the definition of the so-called pros hen structure. This approach takes into account a so-far undescribed distinction of types of examples Aristotle uses and sheds new light on the assessments of the role of the pros hen structure in Aristotle’s philosophy and the theories on development in Aristotle’s thought. Niels Tolkiehn studied Philosophy and Systematic Musicology at the University of Hamburg. He continued his studies as a doctoral student at the Munich School of Ancient Philosophy, a graduate school of the Ludwig-Maximilians-Universität München. Supervised by Prof. Dr. Christof Rapp, he was awarded his doctoral degree in 2019 with this dissertation. (shrink)

In the following pages, the reader will find a detailed study of what Aristotle considered the most difficult aporia formulated in Metaphysics III (Beta), which is answered in chapter 2 of Book X (Iota): the Eleventh Aporia. In such aporia, Aristotle rivals: (i) the conception assumed by the ancient Physiologoi, which takes the One to be an underlying nature whose being is not exhausted by being One, and (ii) the Platonic-Pythagorean view, which prefers to conceive the One in itself, according (...) to its own determinations and apart from any connection with some reality outside it. (shrink)

The Eleventh Aporia results from the breakup of the entire Greek philosophy previous to Aristotle in two manners of conceiving and proposing the first principles (archai), specially the One (to hen): (i) the manner by which Physiologoi conceived the One as a principle, namely, assuming an underlying nature, different from the One in itself, not adequately characterized by the simple fact of being one and which is denoted by the concept of One, and (ii) the manner inaugurated by the Pythagoreans (...) and later endorsed by Plato, marked by the abandonment of the appeal to an underlying nature and by conceiving the One in itself (auto to hen) as a principle, depriving it of any connection with some reality not strictly characterized by being one. Aristotle faces this aporia in Metaphysics Iota 2 and, according to the interpretation I propose: (a) refuses the Pythagorean-Platonic manner of conceiving and proposing principles, (b) endorses the course of action of the Physiologoi, and, in doing so, (c) steps back and retakes the “project” of the Physiologoi at the point where it was interrupted, namely, during the search for a principle of motion. From this scenario, I will try to show that the final outcome of the Eleventh Aporia can be the introduction of the Prime Mover as the properly Aristotelian (and cosmological) candidate to the title of One between the principles.
