Originally published in 1938. This compact treatise is a complete treatment of Aristotle’s logic as containing negative terms. It begins with defining Aristotelian logic as a subject-predicate logic confining itself to the four forms of categorical proposition known as the A, E, I and O forms. It assigns conventional meanings to these categorical forms such that subalternation holds. It continues to discuss the development of the logic since the time of its founder and address traditional logic as it existed in the twentieth century. The primary consideration of the book is the inclusion of negative terms - obversion, contraposition etc. – within traditional logic by addressing three questions, of systematization, the rules, and the interpretation.

The Routledge Guidebook to Aristotle's Nicomachean Ethics introduces the major themes in Aristotle's great book and acts as a companion for reading this key work.

Reissuing works originally published between 1938 and 1993, this set offers a range of scholarship covering Aristotle’s logic, virtues and mathematics as well as a consideration of De Anima and of his work on physics, specifically light. The first two books are in themselves a pair, which investigate the philosopher’s life and his lost works and development of his thought.

Originally published in 1993. This book presents an amended version of R.D. Hick's classic translation of Aristotle's "De Anima" Books 2 and 3, with pertinent extracts from Book 1, together with an introduction and six papers by prominent international Aristotelian scholars. The editor brings together up-to-date discussions of Aristotle's "De Anima", examining central topics such as the nature of perception, perception and thought, thinking and the intellect, the nature of the soul and the relation between body and soul. These papers draw attention to the importance and value of Aristotle's original contributions both to these topics and to philosophical psychology in general. They show the relevance of Aristotle's ancient classical philosophy to contemporary philosophical debate. This book also examines the key issues of Aristotle's thesis and aims to demonstrate its enduring significance. The "De Anima" is placed within a wider Aristotelian framework, and also within a more comprehensive structure, as a contribution to philosophical development and advance.

Originally published in 1991. Philoponus’ long commentary on Aristotle’s definition of light sets up the major concerns, both in optics and theory of light, that are discussed here. Light was of special interest in Neoplatonism because of its being something incorporeal in the world of natural bodies. Light therefore had a special role in the philosophical analysis of the interpenetration of bodies and was also a paradigm for the soul-body problem. The book contains much about the physiology of vision as well as the propagation of light. Several chapters investigate the philosophical theory behind what came to be known as ‘multiplication of species’ in medieval light theory. These issues in the history of science are placed within an analysis of Neoplatonic development of the distinction between Aristotle’s kinesis and energeia. The book treats Philoponus’ philosophy of mathematical science from the point of view of matter, quantity, and three-dimensionality.

This is a detailed exposition of Aristotelian mathematics and mathematical terminology. It contains clear translations of all the most important passages on mathematics in the writings of Aristotle, together with explanatory notes and commentary by Heath. Particularly interesting are the discussions of hypothesis and related terms, of Zeno's paradox, and of the relation of mathematics to other sciences. The book includes a comprehensive index of the passages translated.

Originally published in 1991, this book focuses on the concept of virtue, and in particular on the virtue of wisdom or knowledge, as it is found in the epic poems of Homer, some tragedies of Sophocles, selected writings of Plato, Aristotle, and the Stoic and Epicurean philosophers. The key questions discussed are the nature of the virtues, their relation to each other, and the relation between the virtues and happiness or well-being. This book provides the background and interpretative framework to make classical works on Ethics, such as Plato’s Republic and Aristotle’s Nicomachean Ethics, accessible to readers with no training in the classics.

What can the study of the history of ancient philosophy bring to the study of contemporary philosophical problems and questions? In New Essays on Plato and Aristotle eight distinguished philosophers address topics in Greek philosophy that are connected with current philosophical issues. All the essays are original and include Gilbert Ryle on Dialectic in the Academy and R. M. Hare on Plato’s indictment of mathematicians.

Originally published in 1983. One of the basic capacities of man as a political being is his faculty of judgement. Yet for all the books on concepts like freedom, equality and authority, surprisingly little attention has been given to this topic in the tradition of Western political thought. What is the nature of political judgement? What endows us, as human beings, with the ability to make reasonable judgements about human affairs and to judge the common world we share with others? By what means to we secure validity for our judgements? What are the underlying conditions of this human capacity, and what implications does it have the understanding of politics? These questions, central as they are to any reflection on politics have rarely been addressed in a systematic way. This book examines Kant’s concept of taste and Aristotle’s concept of prudence, as well as recent works of political philosophy by Arendt, Gadamer and Habermas, all crucially influenced by Kant and Aristotle.
