The debate over the value of pleasure among Eudoxus, Speusippus, and Aristotle is dramatically documented by the Nicomachean Ethics, particularly in the dialectical pros-and-cons concerning the so-called argument from contraries. Two similar versions of this argument are preserved at EN VII. 13, 1153b1–4, and X. 2, 1172b18–20. Many scholars believe that the argument at EN VII is either a report or an appropriation of the Eudoxean argument in EN X. This essay aims to revise this received view. It will explain (...) why these two arguments differ in premises, contents and purposes, and why these distinctions matter for a proper assessment of Aristotle’s understanding of pleasure and pain in general and his dialectical art in particular.

Two crucial questions, if unanswered, impede our understanding of Aristotle’s account of pleasure inenx.4-5: What are the activities that pleasure is said to complete? In virtue of what does pleasurealwaysaccompany these activities? The answers fall in place if we read Aristotle as responding to the Delian challenge that the finest, best and most pleasant are not united in one and the same thing. I propose an ‘ethical’ reading ofenx.4 according to which the best activities in question are those integral to (...) the exercise of virtue. (shrink)

La exaltación aristotélica del ideal contemplativo de vida en Ética a Nicómaco X fue muy influyente en la historia de la filosofía y sus efectos se prolongan mucho más allá del Helenismo y de la Antigüedad tardía. Sin embargo, es en Política VII 1-3 donde Aristóteles presenta la consideración más detallada de los géneros de vida y, en particular, la oposición entre la política y la filosófica. El propósito de este trabajo es reconsiderar el elogio de la vida contemplativa del (...) final de la EN y recuperar el significado político que el proemio ético que antecede al diseño de la pólis ideal tiene en esta discusión, con vistas a mostrar la correspondencia que existe entre la redefinición de práxis en Pol. VII 3 y la jerarquía de la felicidad en EN X 7-8. (shrink)

A potentially illuminating aspect of Aristotle’s study of material properties that has been explored far less systematically and comprehensively than composition is his reliance on structural characteristics that are imperceptibly small, but presumably inferable, if not with certainty, at least with a high degree of confidence. This article is meant to elucidate that aspect and to answer three main questions: What is Aristotle’s general explanatory strategy when it comes to the relation between capacities and microstructures? How does he refine certain (...) elements of his explanations, e.g., with respect to specific subtypes of structures and their interaction with the environment? And to what extent could Aristotle’s appeal to microstructures be relevant to debates in contemporary metaphysics and philosophy of science? (shrink)

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)

In the De Generatione et Corruptione II 9, Aristotle aims to achieve the confirmation of his theory of the necessity of the efficient cause. In this chapter he sets out his criticism on the one hand of those who wrongly attributed the efficient cause to other kinds of causality and on the other, of those who ignored the efficient cause. More specifically Aristotle divides all preceding theories which attempted to explain generation and corruption into two groups: i) those which offered (...) an explanation by using the formal cause ii) those which provided an explanation by using the material or the instrumental causes. According to Philopo­nus, when Aristotle reproaches the other philosophers for adducing no proper notion of the efficient cause he alludes to both Anaxagoras and Plato. Regarding Anaxagoras, in our view this cannot be confirmed by internal textual evidence. In terms of Plato, in this chapter we trace an explicit and an implicit criticism of the Platonic Forms as causes. Aris­totle’s implicit criticism is that the Forms are not at all active causes. We can understand better the grounds for this criticism if we also consider his relevant arguments in Book Lambda of his Metaphysics. His explicit criticism, articulated in two arguments, is formulated in GC 335b18–24. We examine the different lines of its interpretation in the second­ary literature, but primarily we focus on Philoponus’ exegesis, which contributes significantly, not only to the clarification of Aristotle’s thinking, but also to the manifestation of the arguments articulated in defence of the Platonic theory of the Forms. In this paper, through the analysis of Philoponus’ exegesis we set out to prove that Aristotle’s criticism of the Platonic causes can be construed from the perspective of either Aristo­telian theory or the Platonic and Neoplatonic influence. Finally, based on Philoponus’ exegesis, we examine Aristotle’s criticism of those who posited matter or instrumental causes as efficient causes. (shrink)

In On Generation and Corruption 1. 10 and 2. 7 Aristotle discusses mixing and mixtures. Recent scholars tend to read the two texts together, thus treating the production of homoeomers in GC 2. 7 as a process of mixing the material elements. I argue that the tendency to treat homoeomers as mixtures of material elements is incorrect: GC 1. 10 explains the mixing of bodies that have already been produced from the elements, whereas GC 2. 7 explains the processes that (...) produce compound bodies from simpler constituents. In GC 2. 7 only the primary contraries mix in the formation of a homoeomer: material elements cannot be constituents of mixtures for theoretical and physical reasons. This makes sense of the production of homoeomers in GC 2. 7 despite worries about mixing the material elements. For Aristotle, the production of homoeomers is simultaneously a process of mixing the primary contraries and generating the homoeomers from the destruction of material elements. (shrink)

Anaximenes is usually considered to be a material monist recognizing transparent atmospheric air as a principle (ἀρχή). In the cosmogonic explanation of the origin of the earth and the heavenly bodies, the Greek term ἀήρ turns out to mean rather ‘opaque damp mist’. However, Not only does it accord with archaic usage, but also with how it was used in his mentor, Anaximander. Yet, in cosmology ἀήρ means ‘air’ serving as stuff on which the earth and the heavenly bodies float. (...) Hence, in keeping with contemporary usage, Anaximenes recognised two kinds of ἀήρ, distinguishing them functionally. Whereas mist is conceived of as a generating substance, air functions only as carrying stuff. (shrink)

This dissertation is a collection of essays exploring the role of metaphor in Aristotle’s scientific method. Aristotle often appeals to metaphors in his scientific practice; but in the Posterior Analytics, he suggests that their use is inimical to science. Why, then, does he use them in natural science? And what does his use of metaphor in science reveal about the nature of his scientific investigations? I approach these questions by investigating the epistemic status of metaphor in Aristotelian science. In the (...) first essay, I defend an interpretation of metaphor as a type of heuristic reasoning: I claim that Aristotle uses metaphor to express conditions an explanation in natural science must meet if it is to explain regular, ordered change. These conditions specify the kinds of causes—particularly unmoved efficient causes—which the inquirer into nature is seeking. In the second essay, I look to Aristotle’s use of certain endoxa or common beliefs as explanatory principles in science, and show that his use of these principles is similar to his use of metaphor. In the final essay, I present a historical study of the analogy of art and nature, and I suggest that by looking to how the Greeks understood the role of inquiry in the arts, we can shed some light on Aristotle’s views concerning the method of inquiry he thinks the natural scientist should adopt.
