The Quaestiones attributed to Alexander of Aphrodisias, the leading ancient commentator on Aristotle, are concerned with physics and metaphysics, psychology and divine providence. They exemplify the process by which Aristotle's thought came to be organised into 'Aristotelianism', and show how interpretations were influenced by the doctrines of Hellenistic philosophy. Some of them, translated into Arabic and thence into Latin, played a part in the transmission of ancient Greek philosophy to the medieval world; and they are still of use today in the interpretation of Aristotle's views on such matters as the problem of universals and the relation between form and matter. The Quaestiones have been studied more and more in recent years; but the present volume and its successor offer the first translation of the whole collection into English or any other modern language.

"Aristotle's Topics is a handbook for dialectic, which can be understood as a philosophical debate between a questioner and a respondent. In book 2, Aristotle mainly develops strategies for making deductions about 'accidents', which are properties that might or might not belong to a subject (for instance, Socrates has five fingers, but might have had six), and about properties that simply belong to a subject without further specification. In the present commentary, here translated into English for the first time, Alexander develops a careful study of Aristotle's text. He preserves objections and replies from other philosophers whose work is now lost, such as the Stoics. He also offers an invaluable picture of the tradition of Aristotelian logic down to his time, including innovative attempts to unify Aristotle's guidance for dialectic with his general theory of deductive argument (the syllogism), found in the Analytics. The work will be of interest not only for its perspective on ancient logic, rhetoric, and debate, but also for its continuing influence on argument in the Middle Ages and later"--

Around 200 AD, the greatest defender and interpreter of Aristotle within his school, Alexander of Aphrodisias, composed his own book On the Soul, partly following the pattern of Aristotle's. In the first half, translated in this volume, he discusses the soul as the form of the body, and the idea of parts or powers that constitute the soul of living things, including the two lowest powers: nutrition and perception. In the second half, translated in Part II, he discusses perception, representation, desire, understanding and - a notion emphasised by the Stoics - the governing part of the soul. He takes the soul to consist of these powers, which supervene on the mixture of the body's elemental ingredients, just as inanimate powers like buoyancy or lightness can supervene on other qualities. They are new, emergent causal powers of the living thing, which do not belong to the constituent ingredients of the body in themselves. Through his notion of emergence, he seeks to steer between the Platonic dualism of soul and body and the extreme materialism of his Stoic rivals. This volume contains the first English translation of the work, as well as a detailed introduction, extensive explanatory notes and a bibliography.
