Something Aristotle calls ‘right logos’ plays a crucial role in his theory of virtue. But the meaning of ‘logos’ in this context is notoriously contested. I argue against the standard translation ‘reason’, and—drawing on parallels with Plato’s work, especially the Laws—in favor of its being used to denote what transforms an inferior epistemic state into a superior one: an explanatory account. Thus Aristotelian phronēsis, like his and Plato’s technē and epistēmē, is a matter of grasping explanatory accounts: in this case, (...) accounts that identify the right action and say why it is right. Arguably, Aristotelian rationality is a matter of being able to grasp accounts in general. (shrink)

When Aristotle speaks of theologikê, he means not the study of a single God, but the study of gods and divine things in general. He never uses the phrase “the unmoved mover” to pick out just one being, and that phrase would not express the essence of the beings it applies to. To see what sort of religious interest there might be in such a being, and how the words “god” and “divine” enter into Aristotle's philosophy, it is best to (...) start with what he says about gods and divine things in moral and political contexts. Guided by his criticisms of Plato on the soul's self-motion, Aristotle sets out, in Physics VIII, to give a revised version of Plato's cosmotheological argument in Laws X. This article focuses on Aristotle's theology and his views about gods, the soul, the cosmos, heavens and heavenly bodies, and the first principle or first cause. (shrink)

At De Anima II 5, 417b17, Aristotle says, ‘The first transition (πρώτη μεταβολή) in that which can perceive is brought about by the parent, and when it is born it already has [the faculty of] sense-perception in the same way as it has knowledge. Actual sense-perception is so spoken of in the same way as contemplation.’ The purpose of this paper is to determine the nature of first transitions.

‘The Union of Cause and Effect in Aristotle : Physics III 3’, Oxford Studies in Ancient Philosophy, 32, pp. 205-232, May 2007.: I argue that Aristotle introduced a unique realist account of causation, which has not hitherto been appreciated in the history of philosophy: causal realism without a causal relation. In his account, cause and effect are unified by the ectopic actualization of the agent’s potentiality in the patient. His solution consists in the introduction of a property that belongs to (...) one subject but is realized in another subject on whose state this realization depends. I identify and analyze the multiple ontological dependencies between the causal state of the agent and that of the patient during their causal activity. (shrink)

In De Anima II 5, 417a21-b16, Aristotle makes a number of distinctions between types of transitions, affections, and alterations. The objective of this paper is to sort out the relationships between these distinctions by means of determining which of the distinguished types of change can be coextensive and which cannot, and which can overlap and which cannot. From the results of this analysis, an interpretation of 417a21-b16 is then constructed that differs from previous interpretations in certain important respects, chief among (...) which is its characterization of transitions from first potentiality to first actuality, e.g., learning, not as `ordinary', but rather as acquisitions of natural dispositions or faculties.

A discussion of Aristotle’s thought on determinism and culpability, Necessity, Cause, and Blame also reveals Richard Sorabji’s own philosophical commitments. He makes the original argument here that Aristotle separates the notions of necessity and cause, rejecting both the idea that all events are necessarily determined as well as the idea that a non-necessitated event must also be non-caused. In support of this argument, Sorabji engages in a wide-ranging discussion of explanation, time, free will, essence, and purpose in nature. He also (...) provides historical perspective, arguing that these problems remain intimately bound up with modern controversies. “ Necessity, Cause and Blame would be counted by all as one of Sorabji’s finest. The book is essential for philosophers—both specialists on the Greeks and modern thinkers about free will—and also compelling for non-specialists.”—Martha Nussbaum “Original and important . . . The book relates Aristotle’s discussions to both the contemporary debates on determinism and causation and the ancient ones. It is especially detailed on Stoic arguments about necessity . . . and on the social and legal background to Aristotle’s thought.”— Choice “It is difficult to convey the extraordinary richness of this book. . . . A Greekless philosopher could read it with pleasure . . . At the same time, its learning and scholarship are enormous.”—G. E. M. Anscombe, Times Literary Supplement. (shrink)

Everson presents a comprehensive new study of Aristotle's account of perception and related mental capacities. Recent debate about Aristotle's theory of mind has focused on this account, which is Aristotle's most sustained and detailed attempt to describe and explain the behavior of living things. Everson places this account in the context of Aristotle's natural science as a whole, showing how Aristotle applies the explanatory tools he developed in other works to the study of perceptual cognition.

In this incisive study Sarah Broadie gives an argued account of the main topics of Aristotle's ethics: eudaimonia, virtue, voluntary agency, practical reason, akrasia, pleasure, and the ethical status of theoria. She explores the sense of "eudaimonia," probes Aristotle's division of the soul and its virtues, and traces the ambiguities in "voluntary." Fresh light is shed on his comparison of practical wisdom with other kinds of knowledge, and a realistic account is developed of Aristototelian deliberation. The concept of pleasure as (...) value-judgment is expounded, and the problem of akrasia is argued to be less of a problem to Aristotle than to his modern interpreters. Showing that the theoretic ideal of Nicomachean Ethics X is in step with the earlier emphasis on practice, as well as with the doctrine of the Eudemian Ethics, this work makes a major contribution towards the understanding of Aristotle's ethics.

Historically embryogenesis has been among the most philosophically intriguing phenomena. In this paper I focus on one aspect of biological development that was particularly perplexing to the ancients: self-organisation. For many ancients, the fact that an organism determines the important features of its own development required a special model for understanding how this was possible. This was especially true for Aristotle, Alexander, and Simplicius, who all looked to contemporary technology to supply that model. However, they did not all agree on (...) what kind of device should be used. In this paper I explore the way these ancients made use of technology as a model for the developing embryo. I argue that their different choices of device reveal fundamental differences in the way each thinker understood the nature of biological development itself. In the final section of the paper I challenge the traditional view (dating back to Alexander's interpretation of Aristotle) that the use of automata in GA can simply be read off from their use in the de motu.

Understanding “what something is” has long occupied philosophers, and no Western thinker has had more influence on the nature of being than Aristotle. Focusing on a reinterpretation of the concept of energeia as “activity,” Aryeh Kosman reexamines Aristotle’s ontology and some of our most basic assumptions about the great philosopher’s thought.

How can we explain the structure of perceptual experience? What is it that we perceive? How is it that we perceive objects and not disjoint arrays of properties? By which sense or senses do we perceive objects? This book investigates Aristotle's views on these and related questions.

Thomas Kjeller Johansen presents a new account of Aristotle's major work on psychology, the De Anima.

Aristotle says that arts such as medicine, the soul, and the heavenly Unmoved Movers are all efficient causes. Because the arts do not seem to fit the model of an efficient cause that does something, scholars have posited two classes of efficient cause, “energetic” and “non-energetic” ones, and have classified the arts, the soul, and the Unmoved Movers as non-energetic. I argue that, once the way an Aristotelian efficient cause produces motion is properly understand, this distinction is not needed: all (...) efficient causes are energetic. I end by proposing a new understanding of the efficient causality of the Unmoved Mover. (shrink)

The concept of "nature as inner principle of change" is fundamental to Aristotle's theory of the physical world; it is the object of the present thesis to substantiate this claim by tracing the effects of this idea in Aristotle's rejection of materialism, in his doctrine of "natural places", in his definition of change and process in general, and in his notion of agency in general and the supreme Unmoved Mover in particular ). Aristotle elucidates "natural" by. contrast with "artificial" - (...) ), holding that natural substances not merely collectively - ) but as individuals each possess an 'innate impulse of change'. But this must be explained so as to allow for the fact that no change is entirely independent of external conditions - ). If, however, change were totally dependent on external conditions, its occurrence would be inexplicable - ), and the very concept of "change" would be incoherent. This latter conclusion emerges from an examination of the ancient paradox of becoming and Aristotle's treatment of it - ). The paradox is expounded -). Aristotle answers it by showing that language assumes a continuing subject of change - ). But this assumption meets the problem only if the metaphysical category of substance is also assumed, and along with it some distinction between substance-constitutive and non-substance-constitutive characteristics - ). The former mark off their subject as a thing of a certain causal type; thus change, in presupposing a substantial subject, presupposes one that makes some causal contribution to its own changes - ). But Aristotle means more than this by 'nature as inner principle'. He holds a natural substance to be the autonomous determinant of certain changes; these therefore are "natural", as manifesting the substantial nature - ). This problematic notion is taken for granted by Aristotle in the Vhys-ics - ), but can be seen to rest on his metaphysic of substance. It is a consequence of this that the natural change of a given substance be of one kind and display a unitary pattern reflecting the unity of the substance ). This view cripples scientific method as we understand it ), but Aristotle's idea of substance anyway cuts him off from the approaches successfully operated in later mechanics and chemistry - ). A summary of the ground so far covered ) introduces a further sense in which Aristotle's natures are "inner" principles of change: the subject of change is not external to the being which is the source of change - ).

Doing and Being confronts the problem of how to understand two central concepts of Aristotle's philosophy: energeia and dunamis. While these terms seem ambiguous between actuality/potentiality and activity/capacity, Aristotle did not intend them to be so. Through a careful and detailed reading of Metaphysics Theta, Beere argues that we can solve the problem by rejecting both "actuality" and "activity" as translations of energeia, and by working out an analogical conception of energeia. This approach enables Beere to discern a hitherto unnoticed (...) connection between Plato's Sophist and Aristotle's Metaphysics Theta, and to give satisfying interpretations of the major claims that Aristotle makes in Metaphysics Theta, the claim that energeia is prior in being to capacity and the claim that any eternal principle must be perfectly good.

'By identifying the extent to which Aristotle's thinking about ethics was shaped by notions drawn from the crafts Angier has thrown new light on a surprising number of topics and has deepened our understanding of tensions within Aristotle's thought. It is by now a rare achievement to have said something new, true and important about Aristotle.' -- Alasdair MacIntyre, Emeritus Professor of Philosophy, University of Notre Dame, USA.

The Chain of Change is the first full-scale philosophical commentary devoted to Aristotle's Physics VII, in which Aristotle argues for the existence of a first, unmoved cosmic mover. This study systematically considers the major issues of the book, and argues for the fundamental importance of Physics VII in our understanding of Aristotelian cosmology and natural science. Physics VII is extant in two versions, and therefore poses special editorial problems. For this reason one of the features of Dr. Wardy's study is (...) the provision of an improved text and translation in both versions. The author's comprehensive comparison of their merits, philosophical and philological, has a significant bearing on our understanding of the nature and evolution of the Aristotelian corpus. The second part of the book is devoted to critical examination of the argument, including one of the most elaborate and challenging in the entire Aristotelian corpus. Throughout, the author concentrates on those points where Aristotle diverges most sharply and provocatively from contemporary presumptions in philosophy and natural science. (shrink)

In this paper we argue that Aristotle operates with a particular theoretical model in his explanation of animal locomotion, what we call the ‘centralized incoming and outgoing motions’ model. We show how the model accommodates more complex cases of animal motion and how it allows Aristotle to preserve the intuition that animals are self-movers, without jeopardizing his arguments for the eternity of motion and the necessary existence of one eternal unmoved mover in Physics VIII. The CIOM model helps to elucidate (...) Aristotle’s two central yet problematic claims, namely that the soul is the efficient cause of animal motion and that it is the internal supporting-point necessary for animal motion. Moreover, the CIOM model helps us to explain the difference between voluntary, involuntary and non-voluntary motions, and to square Aristotle’s cardiocentrism with his hylomorphism, but also, more generally, it provides an interesting way of thinking about the place of intentionality in the causal structure of the world.

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.
