Alexander of Aphrodisias

"In the second half of Book One of the Prior Analytics, Aristotle reflects on the application of the formalized logic has developed in the first half, focusing particularly on the non-modal or assertoric syllogistic developed in the first seven chapters. These reflections lead Alexander of Aphrodisias, who was a great exponent of Aristotelianism in the late second century, to explain and sometimes argue against subsequent developments of Aristotle's logic and alternatives and objections to it, ideas associated mainly with his colleague Theophrastus and with the Stoics." "The other main topic of this part of the Prior Analytics is the specification of a method for discovering true premises needed to prove a given proposition. Aristotle's presentation is sometimes difficult to follow, and Alexander's discussion is extremely helpful to the uninitiated reader. In his commentary on the final chapter translated in this volume, Alexander provides an insightful account of Aristotle's criticism of Plato's method of division."--Jacket.

"The last 14 chapters of book 1 of Aristotle's 'Prior Analytics' are concerned with the representation in the formal language of syllogistic of propositions and arguments expressed in more or less everyday Greek. In his commentary on those chapters, 'Alexander of Aphrodisias' explains some of Aristotle's more opaque assertions and discusses post-Aristotelian ideas in semantics and the philosophy of language. In doing so he provides an unusual insight into the way in which these disciplines developed in the Hellenistic era. He also shows a more sophisticated understanding of these fields than Aristotle himself, while remaining a staunch defender of Aristotle's emphasis on meaning as opposed to Stoics concern with verbal formulation. In his commentary on the final chapter of book 1 Alexander offers a thorough discussion of Aristotle's distinction between denying that something is, e.g., white and asserting that it is non-white."--Bloomsbury Publishing The last 14 chapters of book 1 of Aristotle's "Prior Analytics" are concerned with the representation in the formal language of syllogistic of propositions and arguments expressed in more or less everyday Greek.

"Aristotle's Topics is about dialectic, which can be understood as a debate between two people or the inner debate of one thinker with himself. Its purposes range from philosophical training to discovering the first principles of thought. Its arguments concern the four predicables (definition, property, genus and accident). Aristotle explains how these four fit into his ten categories, and in Book 1 begins to outline strategies for debate, such as the definition of ambiguity. Alexander's commentary on Book 1 discusses how to define Aristotelian syllogistic argument, why it stands up against the rival Stoic theory of interference, and what is the character of inductive interference and of rhetorical argument. He distinguishes inseparable accidents such as the whiteness of snow from defining differentiae such as its being frozen, and considers how these fit into the scheme of categories. He speaks of dialectic as a stochastic discipline in which success is to be judged not by victory but by skill in argument, a view parallel to that sometimes taken in antiquity of medical practice. And he investigates the subject of ambiguity which had also been richly developed since Aristotle by the rival Stoic school."--Bloomsbury Publishing Aristotle's Topics is about dialectic, which can be understood as a debate between two people or the inner debate of one thinker with himself.

"In his work On Sense Perception, Aristotle discusses the material conditions of perception, starting with the sense organs and moving to the material basis of colour, flavour and odour. His Pythagorean account of hues as a ratio of dark to light was enthusiastically endorsed by Goethe against Newton as being true to the painter's experience. Aristotle finishes with three problems about continuity. First, in what sense are indefinitely small colour patches or colour variations perceptible? Secondly, which perceptible leap discontinuously like light to fill a whole space, which have to reach one point before another; and do observers of the latter perceive the same thing if they are at different distances? Thirdly, how does the central sense permit genuinely simultaneous, rather than staggered, perception of different objects? Alexander's highly explanatory commentary is most expansive on these problems of continuity. His battery of objections to vision involving travel, which would lead to collisions and interference by winds, inspired a tradition of grading the five senses in respect of degrees of immateriality and of intentionality. He also introduces us to paradoxes of Diodorus Cronus about the relations of the smallest perceptible to the largest perceptible size."--Bloomsbury Publishing In his work On Sense Perception, Aristotle discusses the material conditions of perception, starting with the sense organs and moving to the material basis of colour, flavour and odour.

The commentary of Alexander of Aphrodisias on Aristotle's Prior Analytics 1.8-22 is a very important text, being the main ancient commentary with chapters in which Aristotle invented modal logic - the logic of propositions about what is necessary or contingent (possible). The first volume of Ian Mueller's translation covered chapters 1.8-13, and reached as far as the chapter in which Aristotle discussed the notion of contingency. In this, the second volume, the 'greatest' commentator, Alexander, concludes his discussion of Aristotle's modal logic. Aristotle also invented the syllogism, a style of argument involving two premises and a conclusion. Modal propositions can be deployed in syllogisms, and in the chapters included in this volume Aristotle discusses all the syllogisms containing at least one contingent premiss. In each volume, Ian Mueller provides a comprehensive explanation of Alexander's commentary on modal logic as a whole.

"Aristotle's Meteorology Book 4 provides an account of the formation of minerals, metals and other homogeneous stuffs. Eric Lewis argues that, in doing so, it offers fresh insight into Aristotle's concept of matter. The four elements (earth, air, fire and water) do have matter, and their matter is the contraries - hot and cold, moist and dry. Lewis further argues that in the text translated here, the only extant ancient commentary on the Meteorology, Alexander of Aphrodisias supports this interpretation of Aristotle. Such a conception of matter complements the account given at an earlier point in the corpus of Aristotle's work in On Generation and Corruption and is confirmed by the account at later points in the biological works, although it adds further detail. Meteorology 4 emerges as an important book. Alexander's commentary is here translated into English for the first time."--Bloomsbury Publishing Aristotle's Meteorology Book 4 provides an account of the formation of minerals, metals and other homogeneous stuffs.

"Aristotle's Metaphysics 2 consists of two chapters on methodology flanking an important discussion of the impossibility of infinite causal chains. The subject is vital for scientific method and for theological belief in a first cause and in a beginning of the universe. Philoponus later attacked Aristotle on this last point, but Alexander presents Aristotle's view in a most favourable light. In Metaphysics 3, Aristotle sets out what he sees as the central problems of metaphysics. Alexander's commentary was subsequently used by the Neoplatonists, two of whom have left their own commentaries, so that Alexander's Aristotelian interpretation can be compared with its rivals."--Bloomsbury Publishing Aristotle's Metaphysics 2 consists of two chapters on methodology flanking an important discussion of the impossibility of infinite causal chains.

"This volume completes the translation in this series of Quaestiones attributed to Alexander of Aphrodisias, the leading ancient commentator on Aristotle. The Quaestiones are concerned with physics and metaphysics, psychology and divine providence. They exemplify the process whereby Aristotle's thought came to be organised into 'Aristotelianism' and show how interpretations were influenced by doctrines of Hellenistic philosophy. Some, translated into Arabic and thence into Latin, played a part in the transmission of ancient Greek philosophy to the medieval world. Those interested in Aristotle's psychological views will find this half of Quaestiones particularly valuable. Ten of the problems discussed explicitly involve issues raised in On the Soul, including the unity of apperception and the transition from first to second actuality in the act of contemplation. A further dozen concern problems in physical theory, including infinity, necessity and potentiality. Quaestio 2.21 concerns divine providence and helps supplement our knowledge of Alexander's position based on surviving Arabic fragments of his On Providence."--Bloomsbury Publishing This volume completes the translation in this series of Quaestiones attributed to Alexander of Aphrodisias, the leading ancient commentator on Aristotle.

"The Supplement transmitted as the second book of On the Soul by Alexander of Aphrodisias (fl. c. 200 AD) is a collection of short texts on a wide range of topics from psychology, including the general hylomorphic account of soul and its faculties, and the theory of vision; questions in ethics (natural instincts, the unity of the virtues, the naturalness of justice and the insufficiency of virtue for happiness); and issues relating to responsibility, chance and fate. One of the texts in the collection, On Intellect, had a major influence on medieval Arabic and Western thought, greater than that of Alexander's On the Soul itself. The treatises may all be by Alexander himself; certainly the majority of them are closely connected with his other works. Many of them, however, consist of collections of arguments on particular issues, collections which probably incorporate material from earlier in the history of the Peripatetic school. This translation is from a new edition of the Greek text based on a collation of all known manuscripts and comparison with medieval Arabic and Latin translations."--Bloomsbury Publishing The Supplement transmitted as the second book of On the Soul by Alexander of Aphrodisias (fl. c. 200 AD) is a collection of short texts on a wide range of topics from psychology, including the general hylomorphic account of soul and its faculties, and the theory of vision; questions in ethics (natural instincts, the unity of the virtues, the naturalness of justice and the insufficiency of virtue for happiness); and issues relating to responsibility, chance and fate.
