Are Potency and Actuality Compatible in Aristotle?

The belief that Aristotle opposes potency (dunamis) to actuality (energeia or entelecheia) has gone untested. This essay defines and distinguishes forms of the Opposition Hypothesis—the Actualization, Privation, and Modal—examining the texts and arguments adduced to support them. Using Aristotle’s own account of opposition, the texts appear instead to show that potency and actuality are compatible, while arguments for their opposition produce intractable problems. Notably, Aristotle’s refutation of the Megarian Identity Hypothesis applies with equal or greater force to the Opposition Hypothesis. For Aristotle, then, potency and actuality are compatible

The Hermeneutic Problem of Potency and Activity in Aristotle

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

How Technology Changes Our Idea of the Good

The ethical neutrality of technology has been widely questioned, for example, in the case of the creation and continued existence of weapons. At stake is whether technology changes the ethical character of our experience: compare the experience of seeing a beating to videotaping it. Interpreting and elaborating on the work of George Grant and Marshall McLuhan, this paper consists of three arguments: 1) the existence of technologies determines the structures of civilization that are imposed on the world, 2) technologies shape what we do and determine how we do it, and 3) technology, unlike any other kind of thing, seems not to make moral demands of us: it is morally neutral. This means that they offer us the freedom of imposing on something that does not impose back. The introduction of this experience of freedom changes the way we experience the world in general by introducing a new way of relating to the good, namely by introducing the act of subjective valuation. Each of these points implies that technology structurally changes or interferes with our ethical relationship with things, with the result that through subjective valuation the experience of the obligation to act can be suspended

Aristotle: Movement and the Structure of Being

Thesis advisor: John SallisThis project sets out to answer the following question: according to Aristotle, what does movement contribute to or change about being? The first part works through the argument for the existence of movement in the Physics. This argument includes distinctive innovations in the structure of being, notably the simultaneous unity and manyness of being: while material and form are one thing, they are two in being. This makes it possible for Aristotle to argue that movement is not intrinsically related to what is not: what comes to be does not emerge from non-being, it comes from something that is in a different sense. The second part turns to the Metaphysics to show that and how the lineage of potency and activity the inquiry into movement. A central problem is that activity or actuality, energeia, does not at first seem to be intrinsically related to a completeness or end, telos. With the unity of different senses of being at stake, Aristotle establishes that it is by showing that activity or actuality is movement most of all, and that movement has and is a complete end. Thus, it is movement that leads Aristotle to conclude that substance and form are energeia, and that unity of being is possible.Thesis (PhD) — Boston College, 2012.Submitted to: Boston College.

The Now and the Relation between Motion and Time in Aristotle: A Systematic Reconstruction

This paper reconstructs the relationship between the now, motion, and number in Aristotle to clarify the nature of the now, and, thereby, the relationship between motion and time. Although it is clear that for Aristotle motion, and, more generally, change, are prior to time, the nature of this priority is not clear. But if time is the number of motion, then the priority of motion can be grasped by examining his theory of number. This paper aims to show that, just as numbers are generated by the soul, time is not presupposed by motion, but emerges through the soul’s articulation of motion. Time is co-constituted by the soul and motion. The now is the key to understanding both the contribution of motion and soul to the being of time. The now is part of the soul’s articulation of motion, and sets the stage for an act that distinguishes a unit from its underlying motion. The now, then, sets up an abstraction by which the soul generates the temporal number from motion. Reconstructing this account of abstraction allows us to formulate more strongly Aristotle’s claim to the ontological dependence of time on motion. The paper then gives a systematic overview of the relationships between the now and number in order to address the question of whether the now might be extended. It closes with an examination of the possibility that motion depends on time, and how universal time is possible

Aristotle's Ontology of Change

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
