Paul Lettinck has restored a lost text of Philoponus by translating it for the first time from Arabic (only limited fragments have survived in the original Greek). The text, recovered from annotations in an Arabic translation of Aristotle, is an abridging paraphrase of Philoponus' commentary on Physics Books 5-7, with two final comments on Book 8. The Simplicius text, which consists of his comments on Aristotle's treatment of the void in chapters 6-9 of Book 4 of the Physics, comes from Simplicius' huge commentary on Book 4. Simplicius' comments on Aristotle's treatment of place and time have been translated by J. O. Urmson in two earlier volumes of this series.

In the sixth century AD Simplicius produced detailed commentaries on several of the works of Aristotle, which help in our understanding of the "Physics", and of its interpretation in the ancient world. This is Urmson's translation of Simplicius' commentaries on "Physics 5" in which Aristotle lays down some of the principles of his dynamics and theory of change. What does not count as a change: change of relation?; the flux of time? There is no change of change, yet acceleration is recognized. Aristotle defines "continuous", "contact" and "next", and uses these definitions in discussing when we can claim that the same change or event is still going on.

Is there such a thing as three-dimensional space? Is space inert or dynamic? Is the division of time into past, present and future real? Does the whole of time exist all at once? Does it progress smoothly or by discontinuous leaps? Simplicius surveys ideas about place and time from the preceding thousand years of Greek Philosophy and reveals the extraordinary ingenuity of the late Neoplatonist theories, which he regards as marking a substantial advance on all previous ideas.

John Stuart Mill's Utilitarianism continues to serve as a rich source of moral and theoretical insight. This collection of articles by top scholars offers fresh interpretations of Mill's ideas about happiness, moral obligation, justice, and rights. Applying contemporary philosophical insights, the articles challenge the conventional readings of Mill, and, in the process, contribute to a deeper understanding of utilitarian theory as well as the complexity of moral life.

Originally published in 1968, this book traces the development of the emotive theory of ethics from its outline by Ogden and Richards in The Meaning of Meaning to the elaborate presentation by Stevenson in Ethics and Language. Attention is paid to the positive features of the ethical theory whilst the author also shows how a more adequate view can be reached through critical reflection on it.

This is the commentary attributed to Simplicius on Aristotle's "On the Soul". It is intended to provide a wider readership with the opportunity to assess the disputed question of authorship. Is the work by Simplicius, or by his colleague Priscian, or by another commentator? The commentary is a source for late Neoplatonist theories of thought and sense perception and provides insight into this area of Aristotle's thought. In this volume the Neoplatonist commentator covers the first half of Aristotle's "On the Soul", comprising Aristotle's survey of his predecessors and his own rival account of the nature of the soul.

On its first appearance in 1960, the Concise Encyclopedia of Western Philosophy established itself as a classic; this third edition builds on its original strengths but brings it completely up to date. The Concise Encyclopedia offers a lively, readable, comprehensive and authoritative treatment of Western philosophy as a whole, incorporating scintillating articles by many leading philosophical authors. It serves not only as a convenient reference work, but also as an engaging introduction to philosophy.

Aristotle's "Physics Book 3" covers two subjects: the definition of change and the finitude of the universe. Change enters into the very definition of nature as an internal source of change. Change receives two definitions in chapters 1 and 2, as involving the actualisation of the potential or of the changeable. Alexander of Aphrodisias is reported as thinking that the second version is designed to show that Book 3, like Book 5, means to disqualify change in relations from being genuine change. Aristotle's successor Theophrastus, we are told, and Simplicius himself, prefer to admit relational change. Chapter 3 introduces a general causal principle that the activity of the agent causing change is in the patient undergoing change, and that the causing and undergoing are to be counted as only one activity, however different in definition. Simplicius points out that this paves the way for Aristotle's God who moves the heavens, while admitting no motion in himself. It is also the basis of Aristotle's doctrine, central to Neoplatonism, that intellect is one with the objects it contemplates. In defending Aristotle's claim that the universe is spatially finite, Simplicius has to meet Archytas' question, "What happens at the edge?". He replies that, given Aristotle's definition of place, there is nothing, rather than an empty place, beyond the furthest stars, and one cannot stretch one's hand into nothing, nor be prevented by nothing. But why is Aristotle's beginningless universe not temporally infinite? Simplicius answers that the past years no longer exist, so one never has in infinite collection.

On the General Science of Mathematics is the third of four surviving works out of ten by Iamblichus (c. 245 CE-early 320s) on the Pythagoreans. He thought the Pythagoreans had treated mathematics as essential for drawing the human soul upwards to higher realms described by Plato, and downwards to understand the physical cosmos, the products of arts and crafts and the order required for an ethical life. His Pythagorean treatises use edited quotation to re-tell the history of philosophy, presenting Plato and Aristotle as passing on the ideas invented by Pythagoras and his early followers. Although his quotations tend to come instead from Plato and later Pythagoreanising Platonists, this re-interpretation had a huge impact on the Neoplatonist commentators in Athens. Iamblichus' cleverness, if not to the same extent his re-interpretation, was appreciated by the commentators in Alexandria.

The influence of J. L. Austin on contemporary philosophy was substantial during his lifetime, and has grown greatly since his death, at the height of his powers, in 1960. Philosophical Papers, first published in 1961, was the first of three volumes of Austin's work to be edited by J. O. Urmson and G. J. Warnock. Together with Sense and Sensibilia and How to do things with Words (both first published in 1962 and both still available), it has extended Austin's influence far beyond the circle who knew him or read the handful of papers he published in journals.

This work sets out Austin's conclusions in the field to which he directed his main efforts for at least the last ten years of his life. Starting from an exhaustive examination of his already well-known distinction between performative utterances and statements, Austin here finally abandons that distinction, replacing it with a more general theory of `illocutionary forces' of utterances which has important bearings on a wide variety of philosophical problems.

Simplicius, the greatest surviving ancient authority on Aristotle's "Physics," lived in the sixth century A. D. He produced detailed commentaries on several of Aristotle's works. Those on the" Physics," which alone come to over 1,300 pages in the original Greek, preserve a centuries-old tradition of ancient scholarship on Aristotle. In "Physics "Book 5 Aristotle lays down some of the principles of his dynamics and theory of change. What does not count as change: change of relation? The flux of time? There is no change of change, yet acceleration is recognised. Aristotle defines 'continuous', 'contact' and 'next', and uses these definitions in discussing when we can claim that the same change or event is still going on. This volume is complemented by David Konstan's translation of Simplicius' commentary on "Physics" Book 6, which has already appeared in this series. It is Book 6 that gives spatial application to the terms defined in Book 5, and uses them to mount a celebrated attack on atomism. Simplicius' commentaries enrich our understanding of the Physics and of its interpretation in the ancient world.

This companion to J. O. Urmson's translation in the same series of Simplicius' "Corollaries on Place and Time "contains Simplicius' commentary on the chapters on place and time in Aristotle's "Physics "book 4. It is a rich source for the preceding 800 years' discussion of Aristotle's views. Simplicius records attacks on Aristotle's claim that time requires change, or consciousness. He reports a rebuttal of the Pythagorean theory that history will repeat itself exactly. He evaluates Aristotle's treatment of Zeno's paradox concerning place. Throughout he elucidates the structure and meaning of Aristotle's argument, and all the more clearly for having separated off his own views into the" Corollaries."

The commentary attributed to Simplicius on Aristotle's "On the Soul "appears in this series in three volumes, of which this is the first. The translation provides the first opportunity for a wider readership to assess the disputed question of authorship. Is the work by Simplicius, or by his colleague Priscian, or by another commentator? In the second volume, Priscian's "Paraphrase of Theophrastus on Sense Perception," which covers the same subject, will also be translated for comparison. Whatever its authorship, the commentary is a major source for late Neoplatonist theories of thought and sense perception and provides considerable insight into this important area of Aristotle's thought. In this first volume, the Neoplatonist commentator covers the first half of Aristotle's "On the Soul," comprising Aristotle's survey of his predecessors and his own rival account of the nature of the soul.
