D.M. Armstrong is an eminent Australian philosopher whose work over many years has dealt with such subjects as: the nature of possibility, concepts of the particular and the general, causes and laws of nature, and the nature of human consciousness. This collection of essays, all specially written for this volume, explore the many facets of Armstrong's work, concentrating on his more recent interests. There are four sections to the book: possibility and identity, universals, laws and causality, philosophy of mind. The contributors comprise an international group of philosophers from the United States, England, and Australia. An interesting feature of the volume is that Armstrong himself has written responses to each of the essays. There is also a complete bibliography of Armstrong's writings.

This book demonstrates the importance of ontology for a central debate in philosophy of mind. Mental causation seems an obvious aspect of the world. But it is hard to understand how it can happen unless we get clear about what the entities involved in the process are. An international team of contributors presents new work on this problem.

Scholars from many different disciplines examine consciousness through the lens of intellectual approaches and cultures ranging from cosmology research and cell biophysics laboratories to pre-Columbian Mesoamerica and Tibetan Tantric Buddhism in a volume that extends consciousness studies beyond the limits of current neuroscience research. The "hard problem" of today's consciousness studies is subjective experience: understanding why some brain processing is accompanied by an experienced inner life. Recent scientific advances offer insights for understanding the physiological and chemical phenomenology of consciousness. But by leaving aside the internal experiential nature of consciousness in favor of mapping neural activity, such science leaves many questions unanswered. In Ontology of Consciousness, scholars from a range of disciplines—from neurophysiology to parapsychology, from mathematics to anthropology and indigenous non-Western modes of thought—go beyond these limits of current neuroscience research to explore insights offered by other intellectual approaches to consciousness. These scholars focus their attention on such philosophical approaches to consciousness as Tibetan Tantric Buddhism, North American Indian insights, pre-Columbian Mesoamerican civilization, and the Byzantine Empire. Some draw on artifacts and ethnographic data to make their point. Others translate cultural concepts of consciousness into modern scientific language using models and mathematical mappings. Many consider individual experiences of sentience and existence, as seen in African communalism, Hindi psychology, Zen Buddhism, Indian vibhuti phenomena, existentialism, philosophical realism, and modern psychiatry. Some reveal current views and conundrums in neurobiology to comprehend sentient intellection.

Object-oriented ontology offers a startlingly fresh way to think about causality that takes into account developments in physics since 1900. Causality, argues, Object Oriented Ontology (OOO), is aesthetic. In this book, Timothy Morton explores what it means to say that a thing has come into being, that it is persisting, and that it has ended. Drawing from examples in physics, biology, ecology, art, literature and music, Morton demonstrates the counterintuitive yet elegant explanatory power of OOO for thinking causality.

We use concepts of causal powers and their relatives-dispositions, capacities, and abilities-to describe the world around us, both in everyday life and in scientific practice. This volume presents new work on the nature of causal powers, and their connections with other phenomena within metaphysics, philosophy of science, and philosophy of mind.

E. J. Lowe sets out and defends his theory of what there is. His four-category ontology is a metaphysical system that recognizes two fundamental categorial distinctions which cut across each other to generate four fundamental ontological categories. The distinctions are between the particular and the universal and between the substantial and the non-substantial. The four categories thus generated are substantial particulars, non-substantial particulars, substantial universals and non-substantial universals. Non-substantial universals include properties and relations, conceived as universals. Non-substantial particulars include property-instances and relation-instances, otherwise known as non-relational and relational tropes or modes. Substantial particulars include propertied individuals, the paradigm examples of which are persisting, concrete objects. Substantial universals are otherwise known as substantial kinds and include as paradigm examples natural kinds of persisting objects. This ontology has a lengthy pedigree, many commentators attributing it to Aristotle on the basis of certain passages in his apparently early work, the Categories. At various times during the history of Western philosophy, it has been revived or rediscovered, but it has never found universal favour, perhaps on account of its apparent lack of parsimony as well as its commitment to universals. In pursuit of ontological economy, metaphysicians have generally preferred to recognize fewer than four fundamental ontological categories. However, Occam's razor stipulates only that we should not multiply entities beyond necessity; Lowe argues that the four-category ontology has an explanatory power unrivalled by more parsimonious systems, and that this counts decisively in its favour. He shows that it provides a powerful explanatory framework for a unified account of causation, dispositions, natural laws, natural necessity and many other related matters, such as the semantics of counterfactual conditionals and the character of the truthmaking relation. As such, it constitutes a thoroughgoing metaphysical foundation for natural science. Contents List

This book explores a range of traditional and contemporary metaphysical themes that figure in the writings of E. J. Lowe, whose powerful and influential work was still developing at the time of his death in 2015. During his forty-year career, he established himself as one of the world's leading philosophers, publishing eleven single-authored books and well over two hundred essays. His scholarship was strikingly broad, ranging from early modern philosophy to the interpretation of quantum mechanics. His most important and sustained contributions were to philosophy of mind, philosophical logic, and above all metaphysics. E. J. Lowe was committed to a systematic, realist, and scientifically informed neo-Aristotelean approach to philosophy. This volume presents a set of new essays by philosophers who share this commitment, addressing interrelated themes of his work. In particular, these papers focus upon three closely connected topics central not only to Lowe's work, but to contemporary metaphysics and philosophy of mind in general: ontology and categories of being; essence and modality, and the metaphysics of mental causation.

Groff's argument runs counter to the familiar anti-metaphysical habit. Social and political philosophy, she maintains, is not as metaphysically neutral as it may seem. Even the most deontological of theories connects up with an attendant set of philosophical commitments regarding what kinds of things exist, as a fundamental ontological matter, and what they are like. These are topics of interest not just to social and political philosophers, but to social scientists and to philosophers of social science as well. "Ruth Groff has broken new ground in demonstrating the connection between social and political thought and the ontology of causal powers. Her account of the structure of Humean thinking about agency is excellent. Especially significant is the role that she assigns to Kantianism in the analysis that she develops. She moves effortlessly between contemporary metaphysics, political theory, critical social theory, and the history of modern philosophy, offering trenchant insights along the way into the work of thinkers ranging from Hume himself to Mill, Adorno, and Martha Nussbaum, and into debates over agent causation and emergence. There is even a discussion, in the final chapter, of Spinoza. This is big-picture philosophy at its best: rigorous and exacting at the level of detail; original, compelling and systematic in the whole." - Stephen Mumford, Professor of Metaphysics and Dean of the Faculty of Arts, University of Nottingham
