David Armstrong sets out his metaphysical system in a set of concise and lively chapters each dealing with one aspect of the world. He begins with the assumption that all that exists is the physical world of space-time. On this foundation he constructs a coherent metaphysical scheme that gives plausible answers to many of the great problems of metaphysics. He gives accounts of properties, relations, and particulars; laws of nature; modality; abstract objects such as numbers; and time and mind.

This book tries to present in brief compass a metaphysical system, matured (as is hoped) over many years. By metaphysics is understood an account of the fundamental categories of being, such notions as property, relation, causality. These notions are more abstract than the results of scientific inquiry, and are controversial among scientists as well as among philosophers. The book sprang from lectures given to graduate students, and has deliberately been kept at an informal level. It includes some explanations not required in a book for professional philosophers. The argument is developed in sixteen short chapters. It is argued that the world is a world of states of affairs, involving universals and particulars. The notion of finding suitable truthmakers for truths grows in importance as the book proceeds.

David Malet Armstrong (8 July 1926–13 May 2014) has been one of the most influential contemporary metaphysicians working in the analytic tradition and surely the greatest 20th century Australian philosopher. His main merit is to have reestablished metaphysics as a respectable branch of philosophy placing it at the centre of the philosophical debate, and giving it the status of an authoritative and competent interlocutor of both rational and empirical sciences. By means of a rigorously argumentative approach and a sharp prose, Armstrong has built a whole metaphysical system, that is, a comprehensive and unified picture of the fundamental structure of the world. The various chapters of the book address the key issues concerning Armstrong' view about the problem of universals, the nature of states of affairs, the ontological ground of possibility, nomic necessity, and dispositions, the truthmaker theory, and the theory of mind. This volume aims to celebrate Armstrong’s memory bringing new understanding, and hopefully stimulating more work, on his philosophy, with the conviction that it constitutes an invaluable heritage for contemporary research in metaphysics.

What distinguishes laws of nature from ordinary facts? What are the "lawmakers": the facts in virtue of which the laws are laws? How can laws be necessary, yet contingent? Lange provocatively argues that laws are distinguished by their necessity, which is grounded in primitive subjunctive facts, while also providing a non-technical and accessible survey of the field.

The decline of religion and ever increasing influence of science pose acute ethical issues for us all. Can we reject the literal truth of the Gospels yet still retain a Christian morality? Can we defend any 'moral values' against the constant encroachments of technology? Indeed, are we in danger of losing most of the qualities which make us truly human? Here, drawing on a novelist's insight into art, literature and abnormal psychology, Iris Murdoch conducts an ongoing debate with major writers, thinkers and theologians—from Augustine to Wittgenstein, Shakespeare to Sartre, Plato to Derrida—to provide fresh and compelling answers to these crucial questions.

John Keller presents a set of new essays on ontology, time, freedom, God, and philosophical method. Our understanding of these subjects has been greatly advanced, since the 1970s, by the work of Peter van Inwagen. In this volume leading philosophers engage with his work, and van Inwagen himself offers selective responses.
