Offers a comprehensive system of analytical metaphysics, argued from a distinctive philosophical perspective.

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 volume presents thirteen original essays which explore both traditional and contemporary aspects of the metaphysics of relations. It is uncontroversial that there are true relational predications-'Abelard loves Eloise', 'Simmias is taller than Socrates', 'smoking causes cancer', and so forth. More controversial is whether any true relational predications have irreducibly relational truthmakers. Do any of the statements above involve their subjects jointly instantiating polyadic properties, or can we explain their truths solely in terms of monadic, non-relational properties of the relata? According to a tradition dating back to Plato and Aristotle, and continued by medieval philosophers, polyadic properties are metaphysically dubious. In non-symmetric relations such as the amatory relation, a property would have to inhere in two things at once-lover and beloved-but characterise each differently, and this puzzled the ancients. More recent work on non-symmetric relations highlights difficulties with their directionality. Such problems offer clear motivation for attempting to reduce relations to monadic properties. By contrast, ontic structural realists hold that the nature of physical reality is exhausted by the relational structure expressed in the equations of fundamental physics. On this view, there must be some irreducible relations, for its fundamental ontology is purely relational. The Metaphysics of Relations draws together the work of a team of leading metaphysicians, to address topics as diverse as ancient and medieval reasons for scepticism about polyadic properties; recent attempts to reduce causal and spatiotemporal relations; recent work on the directionality of relational properties; powers ontologies and their associated problems; whether the most promising interpretations of quantum mechanics posit a fundamentally relational world; and whether the very idea of such a world is coherent. From those who question whether there are relational properties at all, to those who hold they are a fundamental part of reality, this book covers a broad spectrum of positions on the nature and ontological status of relations, from antiquity to the present day.

This volume collects the most important articles on the metaphysics of modality by philosopher Alvin Plantinga. The focus is on such fundamental issues in metaphysics as the nature of abstract objects.

This book addresses the metaphysics of Armstrongian states of affairs, i.e. instantiations of naturalist universals by particulars. The author argues that states of affairs are the best candidate for truthmakers and, in the spirit of logical atomism, that we need no molecular truthmakers for positive truths. In the book's context, this has the pleasing result that there are no molecular states of affairs. Following this account of truthmaking, the author first shows that the particulars in (first-order) states of affairs are bare particulars. He then argues that the properties in states of affairs are simple, non-relational and concrete universals. Next, he argues that (material) relations in states of affairs are external relations. Lastly, he argues that a state of affairs is unified by a distinctive formal relation without giving rise to Bradley’s regress. Written in a relatively non-technical style, the book offers a valuable resource for philosophers working on analytic metaphysics and ontology, as well as their graduate students.

This book models and simulates metaphysics by presenting the metaphysics of a model. The small size of the model makes it possible to treat metaphysical matters with a more than usual systematicity and comprehensiveness. In the mirror of sustained analogy, simulation-metaphysics offers a wealth of insights on the real thing: on the doctrines, the methods, and the epistemology of metaphysics.

This book showcases a range of views on topics at the forefront of current controversies in the field of metaphysics. It will give readers a varied and alive introduction to the field, and cover such key issues as: modality, fundamentality, composition, the object/property distinction, and indeterminacy. The contributors include some of the most important philosophers currently writing on these issues. The questions and philosophers are: Are there any individuals at the fundamental level? / (1) Shamik Dasgupta (2) Jason Turner Is there an objective difference between essential and accidental properties? / (1) Meghan Sullivan (2) Kris McDaniel and Steve Steward Are there any worldly states of affairs? / (1) Daniel Nolan (2) Joseph Melia Are there any intermediate states of affairs? / (1) Jessica Wilson (2) Elizabeth Barnes and Ross Cameron Do ordinary objects exist? / (1) Trenton Merricks (2) Helen Beebee Editor Elizabeth Barnes guides readers through these controversies (all published here for the first time), with a synthetic introduction and succinct abstracts of each debate.

This book, first published in 2004, makes a compelling case for truthmaking and its importance in philosophy.

Mark Jago offers a new metaphysical account of truth. He argues that to be true is to be made true by the existence of a suitable worldly entity. Truth arises as a relation between a proposition - the content of our sayings, thoughts, beliefs, and so on - and an entity (or entities) in the world.

Some of the world's specialists provide in this handbook essays about what kinds of things there are, in what ways they exist, and how they relate to each other. They give the word on such topics as identity, modality, time, causation, persons and minds, freedom, and vagueness.
