Aristotle and Other Philosophers, Misc

This article expands our knowledge of the historical-philosophical process by which the dominant metaphysical account of the Christian God became ascendant. It demonstrates that Marius Victorinus proposed a peculiar model of ‘consubstantiality’ that utilised a notion of ‘existence’ indebted to the Aristotelian concept of ‘prime matter’. Victorinus employed this to argue that God is a unity composed of Father and Son. The article critically evaluates this model. It then argues that Augustine noticed one of the model's philosophical liabilities but did (...) not publicly name Victorinus when he rejected it in De Trinitate, thereby exemplifying the practice of private ‘rebuke’ (ἐλέγχɛιν).

I discuss the argument Aristotle ascribes to Parmenides at Physics 186a23-32. I discuss (i) the reasons why Aristotle considers it as eristic and inconclusive and (i) the solution (lusis) Aristotle proposes against it.

Anaxagoras’ theory of the nous constitutes one aspect of his philosophy particularly interesting for Aristotle. However, he maintains a somewhat bivalent position about it: on the one hand, he praises the Presocratic philosopher for putting the nous as the first principle, while on the other, he shows his disappointment. According to him, Anaxagoras’ nous works insufficiently in the universe, but it is also the cause of goodness, indeed it is the Good capitalized. Our goal is to explain how Aristotle was (...) able to develop both types of seemingly inconsistent discourse concerning Anaxagorean nous. Two solutions to this dilemma are offered: even although some teleology exists in Anaxagoras’ philosophy, it is insufficient for Plato and Aristotle; the reception of the thought of Anaxagoras in later authors still before Aristotle furtively associates goodness with nous.

This volume explores the versatility of the concept of pneuma in philosophical and medical theories in the wake of Aristotle’s physics. It offers fourteen separate studies of how the concept of pneuma was used in a range of physical, physiological, psychological, cosmological and ethical inquiries. The focus is on individual thinkers or traditions and the specific questions they sought to address, including early Peripatetic sources, the Stoics, the major Hellenistic medical traditions, Galen, as well as Proclus in Late Antiquity and (...) John Zacharias Aktouarios in the early 14th century. Building on new scholarly approaches and on recent advancements in our understanding of Graeco-Roman philosophy and medicine, the volume prompts a profound re-evaluation of this fluid and adaptable, but crucially important, substance, in antiquity and beyond.

I examine the reasons Aristotle presents in Physics VIII 8 for denying a crucial assumption of Zeno’s dichotomy paradox: that every motion is composed of sub-motions. Aristotle claims that a unified motion is divisible into motions only in potentiality (δυνάμει). If it were actually divided at some point, the mobile would need to have arrived at and then have departed from this point, and that would require some interval of rest. Commentators have generally found Aristotle’s reasoning unconvincing. Against David Bostock (...) and Richard Sorabji, inter alia, I argue that Aristotle offers a plausible and internally consistent response to Zeno. I defend Aristotle’s reasoning by using his discussion of what to say about the mobile at boundary instants, transitions between change and rest. There Aristotle articulates what I call the Changes are Open, Rests are Closed Rule: what is true of something at a boundary instant is what is true of it over the time of its rest. By contrast, predications true of something over its period of change are not true of the thing at either of the boundary instants of that change. I argue that this rule issues from Aristotle’s general understanding of change, as laid out in Phys. III. It also fits well with Phys. VI, where Aristotle maintains that there is a first boundary instant included in the time of rest, but not a “first in which the mobile began to change.” I then show how this rule underlies Aristotle’s argument that a continuous motion cannot be composed of actual sub-motions. Aristotle distinguishes potential middles, points passed through en route to a terminus, from actual middles. The Changes are Open, Rests are Closed Rule only applies to actual middles, because only they are boundaries of change that the mobile must arrive at and then depart from. On my reading, Aristotle argues that the instant of arrival, the first instant at which the mobile has come to be at the actual middle, cannot belong to the time of the subsequent motion. If it did, the mobile would already be moving towards the next terminus and thus, per Phys. VI 6, would have already left. But it cannot have moved away from the midpoint at the very same moment it has arrived there. This means that the instant of arrival must be separated from the time of departure by an interval of rest. I show how Aristotle’s reasoning applies generally to rule out any continuous reflexive motion or continuous complex rectilinear motion. On my interpretation, however, the argument does not apply to every change of direction. When, as in the case of projectile motion, multiple movers and their relative powers explain why the mobile changes directions, distinct sub-motions are not involved. Aristotle holds that such motions cannot be continuous, not because they involve intervals of rest, but because they involve multiple causes of motion. My interpretation of the Changes are Open, Rests are Closed Rule allows us to make better sense of Aristotle’s argument than any previous interpretation. (shrink)

To study the influence of divinity on cosmos, Alexander uses the notions of ‘fate’ and ‘providence,’ which were common in the philosophy of his time. In this way, he provides an Aristotelian interpretation of the problems related to such concepts. In the context of this discussion, he offers a description of ‘nature’ different from the one that he usually regards as the standard Aristotelian notion of nature, i.e. the intrinsic principle of motion and rest. The new coined concept is a (...) ‘cosmic’ nature that can be identified with both ‘fate’ and ‘divine power,’ which are the immediate effect of providence upon the world. In the paper it is exposed how the conception of providence defended by Alexander means a rejection of the divine care of the particulars, since the divinities are only provident for species. Several texts belonging to the Middle Platonic philosophers will convince us that such thinkers (and not directly Aristotle) are the origin of the thesis that will be understood as the conventional Aristotelian position, namely that divinity only orders species but not individuals.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Spinoza: Une Lecture d'AristoteYitzhak MelamedFrédéric Manzini. Spinoza: Une Lecture d'Aristote. Paris: Presses Universitaires de France, 2009. Pp. 334. Paper, $39.95.The occasion that prompted the current study was the discovery of a tiny typo in the text of Spinoza's Cogitata Metaphysica—the appendix to his 1663 book, Descartes' Principle of Philosophy. As it turned out, this typo, a reference to Book XI instead of Book XII of Aristotle's Metaphysics, was (...) inadvertently reproduced by Spinoza from a contemporary edition of Aristotle's works, allowing Manzini to identify precisely the edition used by Spinoza as the 1548 edition of Aristotle's works printed in Basel by Johannes Oporinus. It also led him to conclude that, contrary to the belief of many, Spinoza read Aristotle's text very closely, and convinced him of the importance of studying the dialogue between the two great philosophers.The book is comprised of three parts, reversing the order of Spinoza's presentation of his philosophy in the Ethics. The first part discusses Spinoza's ethical and political theories—where, the author claims, the influence of Aristotle is most manifest—against the background of the Nicomachean Ethics and the Politics. Here, much attention is given to the notions of the summum bonum and beatitude. The second part discusses Aristotelian and Spinozistic theories of knowledge. In the third and final part, dedicated to metaphysics and first philosophy, the author compares the philosophers' absolutely impersonal conceptions of God, examines their conceptions of substance, and develops a reading of what he calls Spinoza's "ousio-theology" (305).According to Manzini, Aristotle was one of Spinoza's first major philosophical interlocutors, and there is no doubt he is right about this. This conclusion, however, is unsurprising, [End Page 126] since seventeenth-century philosophers, whether devoted Aristotelians or determined anti-Aristotelians, conversed in an Aristotelian philosophical language. Manzini shows that Spinoza engaged directly with Aristotle's text, but also tries to substantiate an even stronger claim by stressing the agreements between the two philosophers.There are two reasons that make it difficult to see Spinoza as being consciously and positively influenced by Aristotle, however. First, Spinoza's dialogue with his philosophical predecessors is, without exception, highly critical and polemical. He does not usually mention philosophers with whom he agrees (e.g. Crescas and Machiavelli). Secondly, several of Spinoza's explicit references to Aristotle are highly critical. Consider, for example, Spinoza's claim, in a letter to Hugo Boxel, that "the authority of Plato, Aristotle, and Socrates carries little weight with me" (Letter 56), or his mockery of the "delusions of the Aristotelians and Platonists" (Theological Political Treatise [TTP], Pref.; cf. ch. 13). Manzini suggests that in these passages Spinoza is not so much addressing Aristotle, but rather using him as a foil to target medieval Aristotelianism (13). Looking closely at the context, my impression is that he is right about the passages in the TTP, but not about the quote from Letter 56. More importantly, the claim that Spinoza uses Aristotle's name as a foil is a double-edged sword that may also serve to undermine Manzini's argument. Throughout the book, Manzini points out interesting and significant similarities between Spinoza's and Aristotle's texts, but to establish direct positive influence one must consider and rule out mediating agents. In the present case there is plenty of evidence that Spinoza read medieval Hebrew Aristotelians closely. Unfortunately, most of the Hebrew authors mentioned by Spinoza were never translated into modern European languages, and there are very few, if any, good studies of Spinoza's dialogue with these texts; in the absence of such translations and studies, some of Manzini's conclusions must remain tentative.Manzini's erudition and analysis of the text are impressive. For example, near the end of his celebrated Letter on the Infinite, Spinoza criticizes "recent Peripatetics" for misunderstanding the ancient method of proving God's existence, citing Crescas's correct formulation of the ancient proof. Manzini rightly points out that the proof Spinoza ascribes to the "recent Peripatetics" was in fact Aristotle's, while the alleged "ancient" proof (which allows for actual infinity and relies on Avicennian...
