Meteorology IV.12, the final chapter of Aristotle’s “chemical” treatise, is a major text for the traditional view that Aristotle believed in universal teleology, the idea that everything in the cosmos—including the elements, earth, water, air, and fire—is what it is because of the goal or good it serves. But in the context of the rest of Meteorology IV, a different picture emerges. Meteorology IV.1–11 analyze the dispositional properties of material compounds (malleability, elasticity, etc.), examine the behavior of stuffs when heated and cooled, and provide the resources to classify kinds in terms of their material composition and dispositional properties. Meteorology IV.12 places itself within that larger investigation but takes a different approach, examining those same materials from the perspective of their functions in bodies of greater complexity (e.g., the function of flesh in an organism). I argue that the teleological account of, say, the elements is limited to their function in the composition of complex kinds, such as living organisms, and that outside such a complex the elements behave as they do, not for the sake of some good they serve but “of necessity,” according to their material natures and interactions with other materials.

Plato famously promised to complement the Sophist and the Statesman with another work on a third sort of expert, the philosopher--but we do not have this final dialogue. Mary Louise Gill argues that Plato promised the Philosopher, but did not write it, in order to stimulate his audience and encourage his readers to work out, for themselves, the portrait it would have contained. The Sophist and Statesman are themselves members of a larger series starting with the Theaetetus, Plato's investigation of knowledge, and the whole series relies on the Parmenides, the second part of which presents a philosophical exercise, introduced as the first step in a larger philosophical program. Gill contends that the dialogues leading up to the missing Philosopher, though they reach some substantive conclusions, are philosophical exercises of various sorts designed to train students in dialectic, the philosopher's method; and that a second version of the Parmenides exercise, closely patterned on it, spans parts of the Theaetetus and Sophist and brings the philosopher into view. This is the exercise about being, the subject-matter studied by Plato's philosopher. Plato hides the pieces of the puzzle and its solution in plain sight, forcing his students (and modern readers) to dig out the pieces and reconstruct the project. Gill reveals how, in finding the philosopher through the exercise, the student becomes a philosopher by mastering his methods. She shows that the target of Plato's exercise is internally related to its pedagogical purpose.

Aristotle's conception of being is dynamic. He believes that a thing is most itself when engaged in its proper activities, governed by its nature. This paper explores this idea by focusing on Metaphysics , a text that continues the investigation of substantial being initiated inMetaphysics Z. Q.1 claims that there are two potentiality-actuality distinctions, one concerned with potentiality in the strict sense, which is involved in change, the other concerned with potentiality in another sense, which he says is more useful for the present project. His present project is the investigation of substantial being, and the relevant potentiality is the potentiality for activity, the full manifestation of what a thing is. I explore Aristotle's two potentiality-actuality distinctions AND argue that the second distinction is modeled on the first, with one crucial modification. Whereas a change is brought about by something other than the object or by the object itself considered as other (as when a doctor cures himself), an activity is brought about byte object itself considered as itself. This single modification yields an important difference: whereas a change leads to a state other than the one an object was previously in, an activity maintains or develops what an object already is.

Dans la première partie duParménide, Socrate présente une théorie des Formes qui explique la comprésence d’opposés dans les choses ordinaires et soutient que les Formes ne peuvent avoir des caractéristiques opposées. Dans la deuxième partie, Parménide s’appuie sur les propos de Socrate; il en dérive des conséquences inacceptables — que la Forme de l’Un n’existe pas, et ainsi, que rien n’existe. Cette conclusion est indéniablement fausse. Pour éviter ceci, Socrate doit abandonner la thèse exposée dans la première partie et trouver une manière de préserver la fonction explicative des Formes. Cet article expose la structure de l’exercice qui occupe la deuxième partie du dialogue.

Aristotle’s notoriously difficult Metaphysics Ζ, which investigates substance, has been the subject of intense debate in the past twenty years. Myles Burnyeat’s Map of Metaphysics Zeta is a ground-breaking intervention in that discussion. Burnyeat examines the overall shape of Ζ, particularly the signposts that structure the argument and link it to the larger project of First Philosophy in Metaphysics, as well as to the Organon. On his approach, to understand what Ζ says, we must first attend to how the issues are addressed and why they are addressed in that way. The result is a book that challenges cherished assumptions and forces the rethinking of Ζ from several new perspectives.
