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.

The thesis that mental states are physical states enjoys widespread popularity. After the abandonment of typeidentity theories, however, this thesis has typically been framed in terms of state tokens. I argue that token states are a philosopher’s fiction, and that debates about the identity of mental and physical state tokens thus rest on a mistake.

The Holocaust throws the study of the history of philosophy into crisis. Critiques of Western thinking leveled by such thinkers as Adorno, Levinas and, more recently, postmodern theorists have suggested that Western philosophy is inherently totalizing and that it must be read differently or altogether abandoned after Auschwitz. This article intentionally rereads Aristotle and Hegel through the shattered lens of the Holocaust. Its refracted focus is the question of ontological identity. By investigating the manner in which the totalizing dimensions of (...) Aristotle’s thinking are both eclipsed and implicitly endorsed by Hegel’s appropriation of Aristotle’s conception of God, and further by following the surplus of Hegel’s (mis)interpretation back into the heart of Aristotle’s ontology where we find a more open conception of ontological identity, we come to recognize not only the dangers endemic to certain strands of traditional philosophical thinking, but also the resources this tradition itself brings to bear on the attempt to think ontological identity after Auschwitz.

We cannot rethink the ethical and political dimensions of memory—especially its role in constituting persons and identities—without rethinking the nature of memory itself. I first describe a traditional epistemological view of memory, according to which memory is a faculty for preserving knowledge of the past, and then juxtapose a relational theory of memory developed by Sue Campbell. The relational theory is represented in terms of a distinction between actions and achievements; this distinction enables us to both clarify and defend the (...) shift from an epistemological to a political conception of memory. On the resulting view, accuracy, not truth, is the appropriate norm for evaluating memory, and remembering is no longer conceived as an interior process. In the penultimate section I confront an objection to a relational theory of memory—and to relational theories of cognition generally—and suggest a strategy of response. (shrink)

In the Physics, Aristotle defines motion as 'the actuality of what is potentially, qua potential' (Phys. 201b5). This definition has been interpreted countless times and has been the subject of heated controvery. At issue today is whether ὲντελέχεια refers to motions as a process or a state. Accordingly, if the idea of ὲντελέχεια is believed to refer to a process, it is translated to mean actualization. If on the other hand it is taken to refer to a state, it is (...) translated as meaning actuality. In the first instance, known as the 'state-view', a change is defined as being the state of a changing object when it is actually potentially F, for some F. In the second, or 'process-view', a change is defined as the actualization of a potentially. It seems to me that both views mistakenly assume that Aristotle succeeded in defining motion as motion. As a consequence, the discussion has focused on a presumed content that the definition does not offer. Indeed, were it the case that Aristotle's definition was adequate, there would hardly be any point in even considering the question of whether he had intended to regard motion as being a state or a process. In this paper I examine both of these views and offer an alternative interpretation of my own that differs markedly from either. Additionally, I shall show that just as Aristotle's definition represents a projection of his particular attitude toward nature - so also recent interpretations of his definition represent a projection of the attitudes of modern thinker's toward Aristotle's philosophy.

This essay aims to analyze the structure of Aristotle's Metaphysics Θ by explicating various senses of the term δύναµις at issue in the treatise. It is argued that Aristotle's central innovation, the sense of δύναµις most useful to his project in the treatise, is the kind of capacity characteristic of the pre-existent matter for substance. It is neither potentiality as a mode of being, as recent studies maintain, nor capacity for `complete' activity. It is argued further that, in starting with (...) the κύριος sense of δύναµις as capacity for change, Aristotle begins with the most familiar and acknowledged kind of capacity, in order to move to the less familiar but ultimately more useful notion of capacity for substance, and to bring these two kinds together through an analogical relation.

The present PhD dissertation aims to examine the relation between modality and change in Aristotle’s metaphysics. -/- On the one hand, Aristotle supports his modal realism (i.e., worldly objects have modal properties - potentialities and essences - that ground the ascriptions of possibility and necessity) by arguing that the rejection of modal realism makes change inexplicable, or, worse, banishes it from the realm of reality. On the other hand, the Stagirite analyses processes by means of modal notions (‘change is the (...) actuality of what is virtual insofar as it is virtual’). In other words: to grasp what change is, one has to resort to the modal idiom of potentialities, while the fact that there is change is indicative of the fact that nature is full of modal properties. -/- Aristotle’s modal and kinetic realism finds a negative in the figure of the Megaric Diodorus Kronus. The polemical situation of Greek philosophy has indeed the dialectical advantage of not opposing the Aristotelian position to a sui generis straw man. Both in its reduction of modal judgements to temporal quantifications and in its dissolution of the reality of the state-of-being-in-motion in favour of a cinematographic view of processes, the philosophical figure of reductionist antirealism embodied by Diodorus constitutes an alternative that takes the opposite view of Aristotle’s realism. -/- The present study is structured as a discussion between these two positions. In the face of Diodorus’ antirealist challenges, Aristotle articulates modal and kinetic considerations: the answers he gives to Diodorus’ puzzles thus provide valuable insight into his metaphysics. Moreover, the examination of Aristotle’s and Diodorus’ metaphysics, because of their insight and originality, will not fail to interest the philosopher concerned with the metaphysical foundations of modern physics, insofar as the entanglement between modalities and processes is nowadays at the core of mechanics (phase spaces, path integrals, etc.).

Of Aristotle’s core terms, potency (dunamis) and actuality (energeia) are among the most important. But when we attempt to understand what they mean, we face the following problem: their primary meaning is movement, as a source (dunamis) or as movement itself (energeia). We therefore have to understand movement in order to understand them. But the structure of movement is itself articulated using these terms: it is the activity of a potential being, as potent. This paper examines this hermeneutic circle, and (...) works out a strategy for reading Aristotle based on his conception of our epistemological predicament. This hermeneutic approach helps us gain access to the phenomena of movement and its sources (potency, and energeia). The paper closes with a review of the conceptual resources we deploy to think about movement: homogeneity, space and time, impulse, relativity, the blend of sameness and difference, and being and non-being. Showing that Aristotle uses none of these clears the landscape for a fresh inquiry into his account of movement. (shrink)
