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 third book of Porphyry's On Abstinence from Animal Food, an ethic of community is developed in order to provide the basis of an account of our ethical obligations to animals. I argue that in spite of Porphyry's rejection of this account, it constitutes a coherent and comprehensive nonanthropocentric ethical theory. It conforms with ethical intuitions insofar as it grants that animals are moral subjects, but does not demand impartiality. By appealing to Theophrastus's notion of to oikeion and to the Stoic notion of oikeic6is it provides the theoretical resources for showing why it is often appropriate to favor human beings over other animals.

Contrā Dale Jamieson, the study of the metaethical foundations of environmental ethics may well lead students to a more environmentally responsible way of life. For although metaethics is rarely decisive in decision making and action, there are two kinds of circumstances in which it can play a crucial role in our practical decisions. First, decisions that have unusual features do not summon habitual ethical reactions, and hence invite the application of ethical precepts that the study of metaethics and ethical theory isolate and clarify. Second, there are times in which the good of others may well be given greater weight in one’s ethical deliberations if theory has made clear that the good to be promoted is ontologically independent of one’s own good.

abstract What gives ethical and political validity to a state? This is to ask what a state is for and to provide a means to determine whether or not a constitution is just. In this paper I compare the account given by Tamir in Liberal Nationalism with that of Rawls, in order to clarify the decisive differences. Although both recognize the importance of particular associations and the moral imperative to be fair, Tamir places priority on the first and Rawls on the second. I explore their practical implications in regard to the ethical defensibility of Israel's self‐identification as a Jewish state and to conflicting nationalistic territorial claims for the Temple Mount in Jerusalem. I suggest that if Tamir is correct in her analysis of nationalism, the Israeli‐Palestinian conflict is a problem that is without the sort of solution that is sought by those who are both interested parties and rational agents of good will

It is now a commonplace that Aristotle and Theophrastus systematically misunderstood Heraclitus in interpreting fire as an ἀρχή of the kind posited by the Milesians. While air in the thought of Anaxamines and the ἄπειρον in the thought of Anaximander can be considered to play the role of the Aristotelian material substrate without too much distortion, this is not so for fire in the thought of Heraclitus. As Cherniss has indicated, while a substrate of the kind posited by the Milesians is a permanent being underlying change, Heraclitean fire is change itself.

Aristotle described the scientific explanation of universal or general facts as deducing them through scientific demonstrations, that is, through syllogisms that met requirements he first formulated of logical validity and explanatoriness. In Chapters 19-23, he adds arguments for the further logical restrictions that scientific demonstrations can neither be indefinitely long nor infinitely extendible through the interposition of new middle terms. Chapters 24-26 argue for the superiority of universal over particular demonstration, of affirmative over negative demonstration, and of direct negative demonstration over demonstration to the impossible. Chapters 27 34 discuss different aspects of sciences and scientific understanding, allowing us to distinguish between sciences, and between scientific understanding and other kinds of cognition, especially opinion. Philoponus' comments on these chapters are interesting especially because of his metaphysical analysis of universal predication and his understanding of the notion of subordinate sciences. We learn from his commentary that Philoponus believed in Platonic Forms as inherent in, and posterior to, the Divine Intellect, but ascribed to Aristotle an interpretation of Plato's Forms as independent substances, prior to the Demiurgic Intellect. A very important notion from Aristotle's Posterior Analytics is that of the 'subordination' of sciences, i.e. the idea that some sciences depend on 'higher' ones for some of their principles. Philoponus goes beyond Aristotle in suggesting a taxonomy of sciences, in which the subordinate science is the same in genus as the superordinate, but different in species.
