This paper examines how within De Caelo Aristotle argues that the heavens rotate to the right, because this is best. I isolate and evaluate its presuppositions and show how it comprises both a dialectical argument to cosmological principles and a partial demonstrative explanation on the basis of such principles. Second, I consider the expressions of epistemological hesitation that Aristotle offers in regard to this (and similar) arguments, and draw conclusions concerning the status of cosmology as an Aristotelian science. In order to "save the phenomena," to allow the endoxon that the heavens are alive and divine to stand, Aristotle needs to make the point that the world and its doings, including all of our human doings, depend on an actuality that is in some sense better than the occasional, incomplete activities in which we engage.

The core sense of pistis as understood in Posterior Analytics, De Anima, and the Rhetoric is not that of a logical relation in which cognitively grasped propositions stand in respect to one another, but the result of an act of socially embedded interpersonal communication, a willing acceptance of guidance offered in respect to action. Even when pistis seems to have an exclusively epistemological sense, this focal meaning of pistis is implicit; to have pistis in a proposition is to willingly accept that proposition as a basis for some kind of activity (albeit possibly theoretical) as a result of some kind of communicative act. This is in accordance with Aristotle’s understanding of argumentation as a social practice, entered into in order lead others to certain actions, for certain ends. Understanding pistis in this way allows us to understand how it is that pistis admits of quantitative variation.

What lies behind Aristotle’s declarations that an attribute or feature that is demonstrated to belong to a scientific subject is proper to that subject? The answer is found in APo. 2.8-10, if we understand these chapters as bearing not only on Aristotle theory of definition but also as clarifying the logical structure of demonstration in general. If we identify the basic subjects with what has no different cause, and demonstrable attributes (the kath’ hauta sumbebēkota) with what do have ‘a different cause’, the definitions of demonstrable attributes necessarily have the minor terms of the appropriate demonstrations in their definitions, for which reason the subjects and demonstrable attributes are coextensive.

Edward Halper’s “The Metaphysics of the Syllogism” argues that the ontological ground of valid inference is found in the necessity of the predications that constitute the premises of the sort of syllogism central to Aristotle’s theory: demonstration. I further support his conclusion on the basis of a consideration of the title and structure of Aristotle’s Analytics, as well as some recent analysis of Aristotle’s modal logic. Halper however suggests that the logical form of inference is a result of how the mind sorts out the elements involved in a complex unity. I suggest that it is not primarily the mind that does this work, but language. What the mind does is primarily to be understood as a reflection of what language does, not vice versa.

What is it for a philosophical account to be atomist? What is the attraction of an atomistic metaphysics? These questions are best approached by considering representative varieties of atomism. The present paper offers a preliminary account of atomism in general and then, in order to shed light on atomism in general and its appeal, considers two very different varieties of atomism: that of Democritus and that of Fredkin’s “digital ontology.” Atomistic accounts are philosophically attractive for two related reasons. First, on an atomistic account, the units of explanation are determinate, and for that reason are in principle ultimately intelligible, as are the complexes derived from them. Both examples of atomism that the author takes as examples display these features. Second, atomism is reductionistic. Ancient atomism has this feature, but it is not an inevitable result of an atomistic strategy. It is absent from Fredkin’s digital ontology.

In this dissertation I present an interpretation of Aristotle's Posterior Analytics II.3-10 according to which Aristotle here outlines the structure of reductive explanations, in which attributes taken to be basic from the standpoint of common sense are analyzed as complexes of theoretical primitives. ;I first discuss the basic features of Aristotle's account of scientific understanding. I then show how an Aristotelian definition of a kind is thought to play two roles: that of grounding all explanations of the attributes of that kind and that of expressing the kind's essence. There follows an examination of the various technical senses of kath' auto. ;Next I discuss Aristotle's distinction between those kinds whose einai is assumed among the first principles of a science and those whose einai is demonstrated. I show that Aristotle's distinction is between the basic kinds studied by a science and the attributes demonstrated to belong to those basic kinds. ;I then turn to my interpretation of Post. An. II.3-10. I argue that Aristotle's distinction between what does not have a cause other than itself and what does is the same as the distinction between basic kinds considered by a science and the attributes of those kinds that are demonstrated to exist. I show that Aristotle is claiming that only those kinds that are not to be considered basic can have their essences explained through demonstration. This is done through a syllogism in which the existence of the conjunction of predicates that is identified with the kind through a nominal definition is shown to follow from certain indemonstrable definitions of other kinds. I argue that such a demonstration constitutes a reductive explanation of the existence and properties of the kind in question, as reductive explanation has been explicated by Sellars. I then show how those nonsubstantial kinds that are taken to be basic by the sciences that study them are in effect considered substantial from the perspective of those sciences

Within The Guide of the Perplexed Maimonides presents an argument that is intended to render probable the temporal creation of the cosmos. In one of these arguments Maimonides adopts the Kalamic strategy of arguing for the necessity of there being a “particularizing” agent. Maimonides argues that even one who grants Aristotelian science can still ask why the heavenly realm is as it is, to which there is no reply forthcoming but “God so willed it.” The argument is effective against the Arabic Neoplatonic Aristotelians, but not against Aristotle himself. Aristotle’s response to Maimonides would be that the latter is in effect asking, “Why are there the essences there are?”, a question that Aristotle would take to be fundamentally misplaced, since he holds that the existence of the theoretical primitives of every science is to be assumed. Nevertheless, Maimonides’ challenge has force for those who recognize a demand for a metaphysical explanation for there being those kinds of things posited as primitive by the natural sciences.

This commentary on Aristotle’s Metaphysics is in a style familiar from the writings of Leo Strauss and his students. The reader is presented with a paraphrase of the whole of Aristotle’s text, marked by seemingly odd omissions, emphases, and offhand remarks. One soon sees that the book is written in code. Only as the book progresses is the author more explicit concerning what he takes to be the main lines of Aristotle’s esoteric teaching, which is as follows.Aristotle writes the Metaphysics for students being initiated into philosophy. These students have already left behind a mythical world-view, but not all are..

The Prior and Posterior Analytics were entitled Ta Analutika by Aristotle himself. But it is not at all clear what Aristotle had in mind in grouping these two works together and in giving them this common title. This question was discussed at length by the ancient Greek commentators on Aristotle. Two main possibilities emerged. The first is that taken by Alexander of Aphrodisias, Ammonius, and Philoponus in his commentary on APr. According to this line of thought, Aristotle has in mind the analysis that shows how a complex arises out of simple entities; both Analytics show us how to subject all lines of syllogistic reasoning (including demonstration) to such analysis. According to the second approach, found in the commentary on APo., 2 attributed to Philoponus, in giving APo., 2 the title 'Analytics' Aristotle has in mind the analysis that reasons from effects to causes. Demonstrations reveal the causes of things, and APo., 2 shows how this is the case. In this paper, the two approaches are compared, and a third approach, which builds on the second, but allows 'Analytics' to have a continuity of sense in its use as a title, is proposed.

This book is an attempt to meet the arguments of scholars who have denied that within the Philebus, generally recognized as a late dialogue, the theory of Forms of the middle dialogues is advocated or plays an important role. Accordingly, instead of a commentary on the argument of the Philebus as a whole, Benitez presents a painstaking analysis of those passages that promise to shed light on Plato's metaphysical and epistemological views at the time of the writing of the Philebus. The result is not for the casual reader, since much of the book is devoted to a careful examination of the Greek text and alternative interpretations. Nonetheless this book will prove profitable for all who are interested in Platonic metaphysics, for Benitez concentrates on developing cogent interpretations of the One-Many problems and the Heavenly Tradition and the Fourfold Classification, two of the most difficult and provocative passages in the Platonic corpus.

Aristotle’s main objection to Pythagorean number ontology is that it posits as a basic subject what can exist only as inherent in a subject. The author then shows how contemporary structural realists posit an ontology much like that of Aristotle’s Pythagoreans. Both take the objects of knowledge to be structure, not the subject of structure. He discusses both how pancomputationalists such as Edward Fredkin approach the Pythagorean account insofar as on their account all reality can in principle be expressed as one (very big) number, made up of discrete units, and even more moderate varieties of structural realism, like that of Floridi, share with pancomputationalism the aspect of “Pythagorean” ontology that Aristotle finds so objectionable: positing structure or form with no substrate. He concludes by arguing that Aristotle himself is drawn to something close or (identical) to a structural realist ontology in Metaphysics 7.3.
