I argue that Plato thinks that a sunaition is a mere tool used by a soul (or by the cosmic nous) to promote an intended outcome. In the first section, I develop the connection between sunaitia and Plato’s teleology. In the second section, I argue that sunaitia belong to Plato’s theory of the soul as a self-mover: specifically, they are those things that are set in motion by the soul in the service of some goal. I also argue against several (...) popular and long-standing interpretations, namely, that sunaitia correspond to Aristotle’s idea of hypothetical necessity, that sunaitia are the ‘how’ in an explanation (whereas the true cause is the ‘why’), and that Plato’s causal views should be read through Aristotle’s fourfold schema. I conclude the article by surveying the history of sunaitia after Plato’s usage. (shrink)

Este artigo contribui para o debate sobre a relação da filosofia prática e teórica de Aristóteles. Ele argumenta que sua filosofia prática depende em grande parte de sua concepção teleológica da natureza. Esta tese é dirigida principalmente contra os estudiosos que sustentam que Aristóteles não deriva de relações políticas e humanas de condições naturais ou cósmicas. O artigo defende a interpretação antropocêntrica de David Sedley da teleologia natural de Aristóteles e mostra como Aristóteles aplica explicações teleológicas às relações de poder (...) entre os seres humanos - entre homens e mulheres e entre homens livres e escravos naturais - e seus propósitos e objetivos. O artigo enfoca o argumento da “função” (ergonomia) humana de Aristóteles, que é um argumento teleológico no centro de sua filosofia prática. Argumenta que este argumento, que Aristóteles apresenta para definir ‘florescimento humano’ ou ‘felicidade’ (eudaimonia), depende de sua definição de homem como o único ‘ser vivo que tem linguagem e razão’ (zôon logon echon). Alega ainda que a disputa sobre se Aristóteles identifica eudaimonia apenas com uma vida de contemplação ou se eudaimonia inclui uma vida política pode ser esclarecida referindo-se ao propósito natural dos logotipos.

This argues for a reading of PA I.1, 639b11-640a9 as a continuous argument, which I divide into 3 main sections. Aristotle’s point in the first section is that teleological explanations should precede non-teleological explanations in the order of exposition. His reasoning is that the ends cited in teleological explanations are definitions, and definitions—which are not subject to further explanation—are appropriate starting points, insofar as they prevent explanations from going on ad infinitum. Moreover, I argue that Aristotle proceeds in the following (...) two sections to criticize certain non-teleological accounts offered by his predecessors on the grounds that they are explanatorily defective: I take Aristotle’s complaints to be that those accounts—unlike teleological explanations—neither begin from appropriate starting points nor entail the phenomena that they purport to explain. Along the way, I am defending an alternative way of understanding what "hypothetical necessity" refers to, for Aristotle. Comments are welcome! (shrink)

In Metaphysics A 6, Aristotle claims that Plato only recognises formal and material causes. Yet, in various dialogues, Plato seems to use and distinguish efficient and final causes too. Consequently, Harold Cherniss accuses Aristotle of being an unfair, forgetful, or careless reader of Plato. Since then, scholars have tried to defend Aristotle’s exegetical skills. I offer textual evidence and arguments to show that their efforts still fall short of the desired goal. I argue, instead, that we can reject Cherniss’ assertation (...) by re-examining Aristotle’s exegetical and methodological assumptions. (shrink)

This paper argues that the account of teleology previously proposed by the authors is consistent with the physical determinism that is implicit across many of the sciences. We suggest that much of the current aversion to teleological thinking found in the sciences is rooted in debates that can be traced back to ancient natural science, which pitted mechanistic and deterministic theories against teleological ones. These debates saw a deterministic world as one where freedom and agency is impossible. And, because teleological (...) entities seem to be free to either reach their ends or not, it was assumed that they could not be deterministic. Mayr’s modern account of teleonomy adheres to this basic assumption. Yet, the seeming tension between teleology and determinism is illusory because freedom and agency do not, in fact, conflict with a deterministic world. To show this, we present a taxonomy of different types of freedom that we see as inherent in teleological systems. Then we show that our taxonomy of freedom, which is crucial to understanding teleology, shares many of the features of a philosophical position regarding free will that is known in the contemporary literature as ‘compatibilism’. This position maintains that an agent is free when the sources of its actions are internal, when the agent itself is the deterministic cause of those actions. Our view shows that freedom is not only indispensable to teleology, but also that, contrary to common intuitions, there is no conflict between teleology and causal determinism. (shrink)

In this paper we examine whether and how powers ontologies can back formal causation. We attempt to answer three questions: i) what is formal causation; ii) whether we need formal causation, and iii) whether formal causation need powers and whether it can be grounded in powers. We take formal causal explanations to be explanations in which something's essence features prominently in the explanans. Three kinds of essential explanations are distinguished: constitutive, consequential, and those singling out something's propria. This last kind (...) of explanation has been somewhat overlooked in the literature, but we argue that it features in much of the most relevant uses of formal explanations in philosophy and science. These are the explanations for why an object has certain propertis that are not, properly speaking, parts of its essence, but that belong to it more intimately than just being part of its consequential essence: they are the properties that ‘flow’ from something's essence. It is argued that a powers metaphysics is uniquely placed to make sense of this last phenomenon. We then distinguish three grades of involvement in which powers might be salient for formal causal explanations: i) powers might be the subject matter of the essence operator, ii) the essence of something might include (or be exhausted) by powers, or iii) powers can explain how propria can flow from something's constitutive existence.

Aristotle is famous for thinking that all our knowledge comes from perception. But it's not immediately clear what this view is meant to entail. It's not clear, for instance, what perception is supposed to contribute to the more advanced forms of knowledge that derive from it. Nor is it clear how we should understand the nature of its contribution—what it might mean to say that these more advanced forms of knowledge are "derived from" or "based on" what we perceive. Aristotle (...) is often thought to have disappointingly little to say on these matters. I argue here that this thought is mistaken: a coherent and philosophically attractive view of perceptual knowledge can be found in the various texts in which Aristotle discusses perception's role in animal life, the cognitive resources on which it does and does not depend, and the relation it bears to practical and theoretical modes of understanding. This book offers a sustained examination of these discussions and their epistemological, psychological, and ethical implications. It defends an interpretation of Aristotle as a moderate sort of empiricist, who thinks that we can develop sophisticated forms of knowledge by broadly perceptual means—and that we therefore share an important part of our cognitive lives with nonrational animals—but also holds that our intellectual powers allow us to surpass these animals in certain ways and thereby develop distinctively human forms of understanding.

We critically reconsider an old hypothesis of the role of the dekad in Pythagorean philosophy. Unlike Zhmud, we claim that: 1) the dekad did play a role in Philolaus’ astronomical system, and 2) Aristotle did not project Plato’s theory of the ten eidetic numbers onto the Pythagoreans. We claim that the dekad, as the τέλειος ἀριθμός, should be understood in Philolaus’ philosophy as completeness and the basis of counting in Greek – as in most other languages – in a decimal (...) system. Additionally, we argue that the number ten is not even a candidate for the τέλειος ἀριθμός in Plato’s philosophy. As a final result of our discussion, we compare and contrast Philolaus’, Plato’s, and Speusippus’ accounts of completeness in relation to numbers. (shrink)

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)

I argue that the science of the soul only covers sublunary living things. Aristotle cannot properly ascribe ψυχή to unmoved movers since they do not have any capacities that are distinct from their activities or any matter to be structured. Heavenly bodies do not have souls in the way that mortal living things do, because their matter is not subject to alteration or generation. These beings do not fit into the hierarchy of soul powers that Aristotle relies on to provide (...) unity to ψυχή. Their living consists in their activities, not in having a capacity for activity.

Aristotle’s theory of human happiness in the Nicomachean Ethics explicitly depends on the claim that contemplation (theôria) is peculiar to human beings, whether it is our function or only part of it. But there is a notorious problem: Aristotle says that divine beings also contemplate. Various solutions have been proposed, but each has difficulties. Drawing on an analysis of what divine contemplation involves according to Aristotle, I identify an assumption common to all of these proposals and argue for rejecting it. (...) This allows a straightforward solution to the problem and there is evidence that Aristotle would have adopted it. (shrink)

Thomas Aquinas is known for having endorsed the view that in our universe everything strives for a certain purpose. According to him not only rational agents act for the sake of specific ends, but every active substance does. It is this claim I reconstruct and discuss in this paper. I argue that it is based on Aquinas’ understanding of causality which is best – or so I suggest – conceived as a dispositional theory of causation. However, Aquinas does not only (...) provide a natural philosophical account of natural teleology. Rather, he substantiates this account by embedding the phenomenon of natural teleology into a monotheistic framework. As I will point out, this move leads to a severe tension in Aquinas’ theory of natural teleology and ultimately threatens to deprive him of his ability to account for the natural substances’ intrinsic teleology. Thomas von Aquin vertrat die Ansicht, dass in unserem Universum alles einen bestimmten Zweck anstrebt. Nicht nur rationale Akteure seien um eines gewissen Ziels tätig, sondern jede aktive Substanz. Hier rekonstruiere und diskutiere ich diese Ansicht. Ich führe aus, dass sie auf Thomas’ Kausalitätsverständnis beruht, das man am besten im Rahmen einer dispositionalen Kausalitätstheorie deuten sollte. Mit Rückgriff auf seinen Monotheismus liefert Thomas neben einer naturphilosophischen Erklärung auch eine theologische Erklärung der Naturteleologie. Wie ich argumentiere, führt diese theologische Einbettung der Naturteleologie zu einer Spannung, welche schließlich die Annahme intrinsischer Teleologie problematisch macht. (shrink)

Greco-Roman meteorology will be described in four overlapping developments. In the archaic period, astro-meteorological calendars were written down, and one appears in Hesiod’s Works and Days; such calendars or almanacs originated thousands of years earlier in Mesopotamia. In the second development, also in the archaic period, the pioneers of prose writing began writing speculative naturalistic explanations of meteorological phenomena: Anaximander, followed by Heraclitus, Anaxagoras, and others. When Aristotle in the fourth century BCE mentions the ‘inquiry that all our predecessors have (...) been calling meteorology’ (338a26), he is referring to these writers. In the third development, the first two enterprises were combined: empirical data collection about meteorological phenomena began to be married to naturalistic theoretical explanation. This innovation was prompted by Democritus and synthesised in its most influential form by Aristotle. At this point more sophisticated techniques of both short-term weather forecasting and long-term speculation about global climate change were also developed. In the fourth development, the wider implications of the naturalistic explanation of meteorological phenomena were contested. The views of ‘meteorologists’ had been controversial since the archaic period because they were perceived, and sometimes intended, to displace the divine prerogatives and undermine traditional religion. These controversies intensified throughout the classical and Hellenistic periods. (shrink)

In his version of atomism, Lucretius made explicit reference to the concept of an intrinsic declination of the atom, the atomic swerve (clinamen in Latin), stressing that the time and space of the infinitesimal atomic vibration is uncertain. The topic of this article is the Epicurean and Lucretian arguments in favour of the swerve. Our exposition of the Lucretian model of the atomic clinamen will present and elucidate the respective considerations on the alleged role of the swerve in the generation (...) of free-action.

In this paper, I discuss the intrinsic value of truth from the perspective of the emotion studies in virtue epistemology. The strategy is the one that looks at epistemic emotions as driving forces towards truth as the most valuable epistemic good. But in doing so, a puzzle arises: how can the value of truth be intrinsic and instrumental? My answer lies in the difference established by Duncan Pritchard between epistemic value and the value of the epistemic applied to the case (...) of subjective motivations to knowing. I argue that the value of truth is intrinsic as epistemic value and that this is not only compatible with the idea that truth can have different kinds of instrumental values but also that the subjective value of truth, disclosed by epistemic emotions, can make the value of truth stronger if regulated within patterns of virtuous enquiry.

Aristotle contrasts episteme and doxa through the key notions of universal and necessary. These notions have played a central role in Aristotle’s characterization of scientific knowledge in the previous chapters of APo. They are not spelled out in APo I.33, but work as a sort of reminder that packs an adequate characterization of scientific knowledge and thereby gives a highly specified context for Aristotle’s contrast between episteme and doxa. I will try to show that this context introduces a contrast in (...) terms of explanatory claims: on the one hand, episteme covers those claims which capture explanatory connections that are universal and necessary and thereby deliver scientific understanding; on the other hand, doxa covers the explanatory attempts that fail at doing so.

The soul is an explanatory principle of Aristotle’s natural science, accounting both for the fact that living things are alive as well as for the diverse natural attributes that belong to them by virtue of being alive. I argue that the explanatory role of the soul in Aristotle’s natural science must be understood in light of his view, stated in a controversial passage from Parts of Animals (645b14–20), that the soul of a living thing is a “complex activity” of its (...) organic body. This paper explores the role of this “complex activity” model of soul in Aristotle’s study of soul in De Anima. I argue, first, that the model has its origins in De Anima II.4, where Aristotle argues that living things do all they do by nature for the sake of a single, teleologically primary end. I argue further that Aristotle uses this model to account for the psychological attributes naturally present in living things, including their capacities for vital activities like nutrition, reproduction, and perception, and that this is the task to which Aristotle devotes the obscure final chapters of De Anima III.

What is virtue? How can we lead moral lives? Exploring how contemporary moral philosophy has led to a revival of interest in the concepts of 'virtue', 'character' and 'flourishing', this is an accessible and critical introduction to virtue ethics.

Despite Diotima’s irresistible virtues and attractiveness across the millennia, she spells trouble for philosophy. It is not her fault that she has been misunderstood, nor is it Plato’s. Rather, I suspect, each era has made of Diotima what it desired her to be. Her malleability is related to the assumption that Plato invented her, that she is a mere literary fiction, licensing the imagination to do what it will. In the first part of my paper, I argue against three contemporary (...) ‘majority views’ about Diotima that I regard as false. The first is that we can be certain she is fictional;1 a second is that Diotima is our best evidence for Plato’s feminism; the third, that she is Plato’s mouthpiece for the higher mysteries in the Symposium. After I have set aside what I regard as false, I proceed in the second half of my paper to develop Diotima’s positive contribution to philosophical psychology, her naturalistic account of the psyche as mortal, unified, and developmental. Whether the view Plato assigns to her is one that he held I do not pretend to know; but it is a powerful, defensible, and coherent view that inspired positive aspects of Freudian psychology in the twentieth century. Freud’s insight, in fact, makes clear how erōs can be developed in relation to the bad as well as the good. (shrink)

Aristotle’s principle that “nature does nothing in vain” (NDNIV) is central to his teleological approach to understanding organisms. First, we argue that James G. Lennox’s influential account of NDNIV is unsuccessful. Second, we propose an alternative account that includes a natural state model. According to a natural state model of development, an organism will develop toward its natural state unless interfering forces prevent that from happening. Third, we argue that this account also fits Aristotle’s discussion in the Generation of Animals (...) and can explain monstrosities in nature that at first sight seem to be counterexamples to NDNIV. Fourth, we take a broader look at NDNIV, arguing that it does not entail that all structures are teleological (since it accommodates the thought that by-products and some neglected items that Aristotle calls “tokens” are nonteleological), that it does not entail that there is only one function per organ, that NDNIV is not an anthropocentric principle, and that, perhaps surprisingly, the teleological structures of an organism can benefit others apart from the organism and its progeny. Finally, we argue that Aristotle endorsed an empirical justification of NDNIV wherein the principle is justified by its many successful applications. (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.

The mental realm seems different to the physical realm; the mental is thought to be dependent on, yet distinct from the physical. But how, exactly, are the two realms supposed to be different, and what, exactly, creates the seemingly insurmountable juxtaposition between the mental and the physical? This review identifies and discusses five marks of the mental, features that set characteristically mental phenomena apart from the characteristically physical phenomena. These five marks (intentionality, consciousness, free will, teleology, and normativity) are not (...) presented as a set of features that define mentality. Rather, each of them is something we seem to associate with phenomena we consider mental, and each of them seems to be in tension with the physical view of reality in its own particular way. It is thus suggested how there is no single mind-body problem, but a set of distinct but interconnected problems. Each of these separate problems is analyzed, and their differences, similarities and connections are identified. This provides a useful basis for future theoretical work on psychology and philosophy of mind, that until now has too often suffered from unclarities, inadequacies, and conflations. (shrink)

A new translation and edition of Aristotle's Protrepticus (with critical comments on the fragments) -/- Welcome -/- The Protrepticus was an early work of Aristotle, written while he was still a member of Plato's Academy, but it soon became one of the most famous works in the whole history of philosophy. Unfortunately it was not directly copied in the middle ages and so did not survive in its own manuscript tradition. But substantial fragments of it have been preserved in several (...) works by Iamblichus of Chalcis, a third century A.D. neo-Pythagorean philosopher and educator. On the basis of a close study of Iamblichus' extensive use and excerption of Aristotle's Protrepticus, it is possible to reconstruct the backbone of the lost work, and then to flesh it out with the other surviving reports about the work from antiquity (for example in Alexander of Aphrodisias and other ancient commentators on Aristotle). It is also possible to identify several papyrus fragments of the work, and many references and literary allusions in later authors, especially Cicero, whose own lost dialogue Hortensius was a defense of philosophy modeleld on Aristotle's.

Plato is commonly considered a metaphysical dualist conceiving of a world of Forms separate from the world of particulars in which we live. This paper explores the motivation for postulating that second world as opposed to making do with the one we have. The main objective is to demonstrate that and how everything, Forms and all, can instead fit into the same world. The approach is exploratory, as there can be no proof in the standard sense. The debate between explaining (...) Plato’s ontology with a single world and requiring a two-world model to make sense of the same thing is typically about scouring the Platonic corpus for evidence and turning to Aristotle for help where we need it. The aim here is to dig deeper than what either of them, or anyone else, has said or implied about the number or worlds, searching instead for any insight that might be gained from the way Forms are supposed to exist versus what we ourselves might understand by existence. Although the paper is, at its most basic level, about the existence of the Forms, the intention is not to prove that they exist, nor to evaluate the proofs and objections already on record, but to consider how they might exist and what follows if they do. Dialogue toward consensus on why we think the Forms exist, and why we think they do not, could perhaps provide a smoother “second sailing” in waters where we have been unable to agree whether they do and where they would if they did.

In this paper I outline a role for mechanistic conceptions of organisms in ancient Greek natural philosophy, especially the study of organisms. By ‘mechanistic conceptions’ I mean the use of ideas and techniques drawn from the field of mechanics to investigate the natural world. ‘Mechanistic conceptions’ of organisms in ancient Greek philosophy, then, are those that draw on the ancient understanding of the field called ‘mechanics’ — hê mêchanikê technê—to investigate living things, rather than those bearing some perceived similarity to (...) modern notions of ‘the mechanical.’ I have argued elsewhere that evidence of mechanistic conceptions of the natural world can be found, not only among seventeenth and eighteenth century ‘mechanical philosophers,’ but also—albeit in vestigial form — in some ancient Greek texts. Unfortunately, these reports are slight, often by detractors of this approach, and offer only clues as to the motivational context for employing these mechanical conceptions. Here, my purpose is to suggest what role they might have played in the history of natural philosophy. (shrink)

It has become somewhat of a platitude to call Aristotle the first epigenesist insofar as he thought form and structure emerged gradually from an unorganized, amorphous embryo. But modern biology now recognizes two senses of “epigenesis”. The first is this more familiar idea about the gradual emergence of form and structure, which is traditionally opposed to the idea of preformationism. But modern biologists also use “epigenesis” to emphasize the context-dependency of the process itself. Used in this sense development is not (...) simply the unfolding of a pre-determined sequence of changes specified in advance by the organism’s genotype. It is also sensitive to inputs from the internal and external environment, which help determine in real-time which of the many potential developmental pathways are actualized during the process. Within this paradigm developing embryos are viewed as dynamic and responsive systems that react to inputs from the internal and external environment ‘on the fly’. In this paper I argue that, while Aristotle was an epigenesist in the first sense, he would have rejected epigenesis in the more modern sense. First, Aristotle’s model of choice for a developing embryo is the automaton that executes a set of preset movements (GA 734b9-13, 741b7-15). The automatons he has in mind are not dynamic AI systems capable of modifying their behaviour on the fly in response to environmental cues but completely deterministic mechanisms whose movements are fixed by their original design. Second, given Aristotle’s views about the different kinds of causal powers there are, it looks like only intentional agents endowed with actual decision-making powers could be capable of the sort of plasticity at the core of a more dynamic epigenesis. For that kind of epigenesis requires powers for alternative outcomes, and Aristotle is explicit that such powers require rational desires (προαίρεσις) that control which of those alternatives to bring about. If I am right, then he could not have made sense of the idea of a developing embryo (as a non-intentional system) making adjustments to its phenotype on the fly in response to emerging problems and opportunities, given the conceptual resources available to him.

This thesis is devoted to studying two historical philosophical events that happened in the West and the East. A metaphysical crisis stimulated Kant’s writings during his late critical period towards the notion of the supersensible. It further motivated a methodological shift and his coining of reflective judgment, which eventually brought about a systemic unfolding of his critical philosophy via Kantian moral teleology. Zhu Xi and his Neo-Confucian contemporaries confronted a transformed intellectual landscape resulting from the Neo-Daoist and Buddhist discourses of (...) “what is beyond the form”. The revival of Confucianism required a method in order to relocate the formless Dao back into daily life and to reconstruct a meta-ethical foundation within a social context. This led to the Neo-Confucian recasting of “investigation of things” from The Great Learning via complex hermeneutic operations. By the respective investigation on, as well as the comparative analysis of the two events, I reveal the convergence and incommensurability between the two distinct cultural traditions concerning the metaphysical quests, the mechanism of intellectual development, and moral teleology, so as to capture the intrinsic characteristics of philosophical research in general.

As a practicing life scientist, Descartes must have a theory of what it means to be a living being. In this paper, I provide an account of what his theoretical conception of living bodies must be. I then show that this conception might well run afoul of his rejection of final causal explanations in natural philosophy. Nonetheless, I show how Descartes might have made use of such explanations as merely hypothetical, even though he explicitly blocks this move. I conclude by (...) suggesting that there is no reason for him to have blocked the use of hypothetical final causes in this way. (shrink)

A commentary on the Symposium as a challenge and a gift to Athens. I begin with a reflection on three dates: 416 bce, the date of Agathon’s victory party, c. 400, the approximate date of Apollodorus’ retelling of the party, and c. 375, the approximate date of the ‘publication’ of the dialogue, and I argue that Plato reminds his contemporary Athens both of its great poetic and legal and scientific traditions and of the historical fact that the way late fourth (...) century Athens appropriated them in some way led to the city’s demise at the turn of the century; thus the dialogue is Plato’s challenge to his contemporary Athens to recognize and overcome its flawed relation to its cultural resources. Heard in this way, the key moments are Aristophanes’ implied critique of Pausanias and Eryximachus and Socrates’ implied critique of Aristophanes and Agathon. Proceeding by a close reading, I argue that Plato exposes, for those moved to rise to his challenge, the failure of his great predecessors to conceive the divine in a way that, worthy of the height and otherness divinity requires, can provide substantive orientation for the burgeoning new reason that animates the city’s culture.

The article tries to prove that the famous formula "epekeina tês ousias" has to be understood in the sense of being beyond being and not only in the sense of being beyond essence. We make hereby three points: first, since pure textual exegesis of 509b8–10 seems to lead to endless controversy, a formal proof for the metaontological interpretation could be helpful to settle the issue; we try to give such a proof. Second, we offer a corollary of the formal proof, (...) showing that not only self-predication of the form of the Good, but of any form is not possible, that is: no form of F has the form of F. Third, we apply Spinoza’s distinction between an ens imaginarium and a chimaera to Plato’s Idea of the Good. (shrink)

Aristotle’s views on the choiceworthiness of friends might seem both internally inconsistent and objectionably instrumentalizing. On the one hand, Aristotle maintains that perfect friends or virtue friends are choiceworthy and lovable for their own sake, and not merely for the sake of further ends. On the other hand, in Nicomachean Ethics IX.9, Aristotle appears somehow to account for the choiceworthiness of such friends by reference to their utility as sources of a virtuous agent’s robust self-awareness. I examine Aristotle’s views on (...) the utility and choiceworthiness of friends, and offer a novel reading of Nicomachean Ethics IX.9. On this reading, Aristotle accepts a version of instrumental conditionalism about final value, that is, the thesis that goods (including friends) can be choiceworthy for their own sake (i.e., possess final or end value) at least partly on account of their instrumental properties. In articulating what sort of instrumental conditionalism it is reasonable to attribute to Aristotle, I argue that Aristotle appeals to the utility of perfect friends as part of a broadly material causal account of why such friends are choiceworthy for their own sake. On this reading, perfect friends are not choiceworthy for the sake of their utility in eliciting self-awareness; rather, their choiceworthiness for their own sake is (at least partly) realized in, or constituted by, their conduciveness to the virtuous agent’s self-awareness. This reading, I argue, frees Aristotle from the charge of inconsistency: Aristotle can appeal to the conduciveness of perfect friends to the virtuous agent’s self-awareness as a way of explaining why such friends are choiceworthy for their own sake.

Translation of Aristotle's Physics I-II into Portuguese, with commentaries. Tradução para o português dos livros I e II da Física de Aristóteles, com comentários.

Aristotle says that only humans can speak and the speech capability is a proper criterion of humanity. Speech is also designated by Aristotle to indicate the right and the wrong. He finishes by saying that it is partnership in these things that makes a city. Ultimately a human being who is not in a polis, would not really be a human being at all? Would this human being then be no more human than a statue with a human form?

Much has been made of how Darwinian thinking destroyed proofs for the existence of God from ‘design’ in the universe. I challenge that prevailing view by looking closely at classical ‘teleological’ arguments for the existence of God. One version championed by Aristotle and Thomas Aquinas stems from how chance is not a sufficient kind of ultimate explanation of the universe. In the course of constructing this argument, I argue that the classical understanding of teleology is no less necessary in modern (...) Darwinian biology than it was in Aristotle's time. In fact, modern biology strengthens the claims that teleological arguments make by vindicating many of their key features. As a consequence, I show how Aristotle and Aquinas' teleological argument for an intelligent First Cause remains valid. (shrink)

Despite the renewed interest in Aristotle’s Generation of Animals in recent years, the subject matter of GA V, its preferred mode(s) of explanation, and its place in the treatise as a whole remain misunderstood. Scholars focus on GA I-IV, which explain animal generation in terms of efficient-final causation, but dismiss GA V as a mere appendix, thinking it to concern (a) individual, accidental differences among animals, which are (b) purely materially necessitated, and (c) are only tangentially related to the topics (...) discussed in the earlier books. In this paper, we defend an alternative and more integrated account of GA V by closely examining Aristotle’s methodological introduction in GA V.1 778a16-b19 and his teleological explanation of the differences of teeth in GA V.8. We argue for the unity of both GA V and of GA as a whole and present a more nuanced theory of teleological explanation in Aristotle’s biology. (shrink)

Aristotle's claim that natural slaves do not possess autonomous rationality (Pol. 1.5, 1254b20-23) cannot plausibly be interpreted in an unrestricted sense, since this would conflict with what Aristotle knew about non-Greek societies. Aristotle's argument requires only a lack of autonomous practical rationality. An impairment of the capacity for integrated practical deliberation, resulting from an environmentally induced excess or deficiency in thumos (Pol. 7.7, 1327b18-31), would be sufficient to make natural slaves incapable of eudaimonia without being obtrusively implausible relative to what (...) Aristotle is likely to have believed about non-Greeks. Since Aristotle seems to have believed that the existence of people who can be enslaved without injustice is a hypothetical necessity, if those capable oí eudaimonia are to achieve it, the existence of natural slaves has implications for our understanding of Aristotle's natural teleology.

It has often been noted that Margaret Cavendish discusses God in her writings on natural philosophy far more than one might think she ought to given her explicit claim that a study of God belongs to theology which is to be kept strictly separate from studies in natural philosophy. In this article, I examine one way in which God enters substantially into her natural philosophy, namely the role he plays in her particular version of teleology. I conclude that, while Cavendish (...) has some resources with which to partially alleviate this tension, she is nonetheless left with a significant difficulty. (shrink)

Partindo de um sentido prescritivo de necessidade, própria do que é condição depossibilidade para a realização de um certo objetivo, analiso inicialmente o procedimentoscotista de neutralização de duas abordagens tradicionais sobre a necessidade da metafísica.Há, por um lado, a neutralização da pretensão dos philosophi de demonstrar a suficiênciada metafísica para a consecução de nosso fim último; e, por outro, a neutralizaçãoda tentativa dos theologi de provar a insuficiência da metafísica para a realização daquelemesmo fim. O procedimento de Scotus de justificação (...) da necessidade da metafísica será emseguida reconstruído, um procedimento que incorpora frente à tradição traços de umaprofunda redefinição dos objetivos e procedimentos daquela ciência.

Each Aristotelian science consists in the causal investigation of a specific department of reality. If successful, such an investigation results in causal knowledge; that is, knowledge of the relevant or appropriate causes. The emphasis on the concept of cause explains why Aristotle developed a theory of causality which is commonly known as the doctrine of the four causes. For Aristotle, a firm grasp of what a cause is, and how many kinds of causes there are, is essential for a successful (...) investigation of the world around us. (shrink)

The manifest appearance of function and purpose in living systems is responsible for the prevalence of apparently teleological explanations of organismic structure and behavior in biology. Although the attribution of function and purpose to living systems is an ancient practice, teleological notions are largely considered ineliminable from modern biological sciences, such as evolutionary biology, genetics, medicine, ethology, and psychiatry, because they play an important explanatory role. Historical and recent examples of teleological claims include the following: The chief function of the (...) heart is the transmission and pumping of the blood through the arteries to the extremities of the body. (Harvey 1616 [1928: 49]) The Predator Detection hypothesis remains the strongest candidate for the function of stotting [by gazelles]. (Caro 1986: 663) The geographic range of human malaria is much wider than the range of the sickle-cell gene. As it happens, other antimalarial genes take over the protective function of the sickle-cell gene in … other warm parts. (Diamond 1994: 83) Despite the substantial amount of data we now have on theropod dinosaurs, more information is necessary in order to determine the likelihood that early feathers served an adaptive function in visual display as opposed to other proposed adaptive functions such as thermoregulation. (Dimond et al. 2011: 62) The ubiquity of claims such as these raises the question: how should apparently teleological notions in biology be understood? Most post-Darwinian approaches attempt to naturalize teleology in biology, in opposition to nineteenth-century viewpoints which grounded it theologically. Nevertheless, biologists and philosophers have continued to question the legitimacy of teleological notions in biology. For instance, Ernst Mayr (1988), identified four reasons why teleological notions remain controversial in biology, namely that they are: vitalistic (positing some special ‘life-force’); requiring backwards causation (because goal-directed explanations seem to use future outcomes to explain present traits); incompatible with mechanistic explanation (because of 1 and 2); mentalistic (attributing the action of mind where there is none). A fifth complaint is that they are not empirically testable (Allen & Bekoff 1995). The current philosophical literature offers both Darwinian and non-Darwinian accounts of teleology in biology that aim to avoid these concerns. In this article, we hope to bring some clarity to the contemporary debates over the role of teleological notions in biology by sketching a taxonomy of the various accounts of biological function on offer (see Allen & Bekoff 1995 for a more comprehensive taxonomy that forms the basis of this presentation). We primarily focus on naturalistic accounts of biological function, since this is where we see the most lively and productive current debates (see, e.g., Garson 2016 for an extended survey). We also briefly discuss the notion of goal-directedness in section 2. (shrink)

This article is the first one to offer an investigation, from a biological perspective, of “natural philia” or “kin-based” philia in Aristotle’s practical philosophy. After some preliminary considerations about its place in Aristotle’s ethical treatises, the discussion focuses on Aristotle’s biology. Here we learn that natural philia, couched in terms of a biological praxis rather than a trait of character, is widespread in the animal kingdom, although in different ways and to varying degrees. To account for such differences, Aristotle establishes (...) a Scala Philiae in two different biological texts—Historia Animalium and Generation of Animals—where natural bonds in animals are classified in view of their strength and duration. Each level of Aristotle’s Scala is examined. Finally, the argument returns to Aristotle’s ethical and political texts, drawing greater attention to the biological mechanisms that underlie natural philia in human beings. I conclude that natural philia provides one fundamental biological building-block of Aristotle’s ethics and politics. (shrink)
