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.



In the second half of book 1 of the "Prior Analytics," Aristotle reflects on the application of the formalized logic he 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, the great late second-century AD exponent of Aristotelianism, 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.

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.

Aristotle's "Meterology Book 4" provides an account of the formation of minerals, metals and other homogeneous stuffs. In doing so, this text argues, it offers us fresh and important insights into Aristotle's conception of matter. The 15,000 pages of the ancient Greek commentators on Aristotle, written mainly between 200 and 600 AD, constitute the largest corpus of extant Greek philosophical writing not translated into English or other European languages. This is a new series of translations, planned in 60 volumes which fills an important gap in the history of European thought.



Quaestiones

by of Aphrodisias Alexander

Published 31 December 1992
Most of the minor texts attributed to Alexander of Aphrodisias were organized into collections in antiquity. Three books of the collected works, which are characterized as "school-discussion problems and solutions on nature," are commonly cited as Alexander's Quaestiones. The first book of the Quaestiones and the first half of the second book, here translated, are concerned with physics, metaphysics, psychology, and divine providence.


Inspired by discussions of Aristotle's works among Alexander and associates of his, the Quaestiones illuminate the functioning of a philosophical school in the early third century A.D. In their emphasis on resolving apparent anomalies and contradictions, they exemplify the process by which Aristotle's thought came to be regarded as "Aristotelianism," and they reveal the influence of the doctrines of Hellenistic philosophy. The translation of some of these first into Arabic and then into Latin played and important role in the transmission of ancient Greek philosophy to the medieval world. Of more than historical interest, Alexander's Quaestiones cast light on Aristotle's views on such issues as the problem of universals and the relation between form and matter.


The Quaestiones have received increasing attention in recent years; this volume, along with its projected sequel, will make all of the text available for the first time in modern language. Students and scholars in the fields of ancient philosophy, classics, and medieval studies will warmly welcome it.

The commentary of Alexander of Aphrodisias on Aristotle's Prior Analytics 1.8-22 is the main ancient commentary, by the 'greatest' commentator, on the chapters of the Prior Analytics in which Aristotle invented modal logic - the logic of propositions about what is necessary or contingent (possible). In this volume, which covers chapters 1.8-13, Alexander of Aphrodisias reaches the chapter in which Aristotle discusses the notion of contingency. Also included in this volume is Alexander's commentary on that part of Prior Analytics 1.17 which explains the conversion of contingent propositions (the rest of 1.17 is included in the second volume of Mueller's translation).
Aristotle also invented the syllogism, a style of argument involving two premises and a conclusion. Modal propositions can be deployed in syllogism, and in the chapters included in this volume Aristotle discusses syllogisms consisting of two necessary propositions as well as the more controversial ones containing one necessary and one non-modal premiss. The discussion of syllogisms containing contingent propositions is reserved for Volume 2.
In each volume, Ian Mueller provides a comprehensive explanation of Alexander's commentary on modal logic as a whole.

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.

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.





The 15,000 pages of the ancient Greek commentators on Aristotle, written mainly between 200 and 600 AD, constitute the largest corpus of extant Greek philosophical writings not translated into English or other European languages. This series of translations with introductions, copious notes and indexes fills an important gap in the history of European thought.
