Are the particles of modern physics "real" or are they virtual entities, their existence deduced merely by abstract theories? This book examines the continuing debate regarding the inner constitution of matter by exploring the particle concept in physics. It investigates if the particles of particle physics are real or not. Readers interested in the "true meaning" of such physical concepts will find this book informative and thought provoking.

Metaphysicians should pay attention to quantum mechanics. Why? Not because it provides definitive answers to many metaphysical questions-the theory itself is remarkably silent on the nature of the physical world, and the various interpretations of the theory on offer present conflicting ontological pictures. Rather, quantum mechanics is essential to the metaphysician because it reshapes standard metaphysical debates and opens up unforeseen new metaphysical possibilities. Even if quantum mechanics provides few clear answers, there are good reasons to think that any adequate understanding of the quantum world will result in a radical reshaping of our classical world-view in some way or other. Whatever the world is like at the atomic scale, it is almost certainly not the swarm of particles pushed around by forces that is often presupposed. This book guides readers through the theory of quantum mechanics and its implications for metaphysics in a clear and accessible way. The theory and its various interpretations are presented with a minimum of technicality. The consequences of these interpretations for metaphysical debates concerning realism, indeterminacy, causation, determinism, holism, and individuality (among other topics) are explored in detail, stressing the novel form that the debates take given the empirical facts in the quantum domain. While quantum mechanics may not deliver unconditional pronouncements on these issues, the range of possibilities consistent with our knowledge of the empirical world is relatively small-and each possibility is metaphysically revisionary in some way. This book will appeal to researchers, students, and anybody else interested in how science informs our world-view.

Hud Hudson presents an innovative view of the metaphysics of human persons according to which human persons are material objects but not human organisms. In developing his account, he formulates and defends a unique collection of positions on parthood, persistence, vagueness, composition, identity, and various puzzles of material constitution.The author also applies his materialist metaphysics to issues in ethics and in the philosophy of religion. He examines the implications for ethics of his metaphysical views for standard arguments addressing the moral permissibility of our treatment of human persons and their parts, fetuses and infants, the irreversibly comatose, and corpses. He argues that his metaphysics provides the best foundation in the philosophy of religion for the Christian doctrine of the resurrection of the body.Hudson addresses a broad range of metaphysical issues, but among his most strikingly original contributions are his defense of the "Partist" view (according to which a material object can exactly occupy multiple, overlapping regions of spacetime) and his argument for the compatibility of Christianity with a materialistic theory of human persons.

Every Thing Must Go argues that the only kind of metaphysics that can contribute to objective knowledge is one based specifically on contemporary science as it really is, and not on philosophers' a priori intuitions, common sense, or simplifications of science. In addition to showing how recent metaphysics has drifted away from connection with all other serious scholarly inquiry as a result of not heeding this restriction, they demonstrate how to build a metaphysics compatible with current fundamental physics ('ontic structural realism'), which, when combined with their metaphysics of the special sciences ('rainforest realism'), can be used to unify physics with the other sciences without reducing these sciences to physics itself. Taking science metaphysically seriously, Ladyman and Ross argue, means that metaphysicians must abandon the picture of the world as composed of self-subsistent individual objects, and the paradigm of causation as the collision of such objects. Every Thing Must Go also assesses the role of information theory and complex systems theory in attempts to explain the relationship between the special sciences and physics, treading a middle road between the grand synthesis of thermodynamics and information, and eliminativism about information. The consequences of the author's metaphysical theory for central issues in the philosophy of science are explored, including the implications for the realism vs. empiricism debate, the role of causation in scientific explanations, the nature of causation and laws, the status of abstract and virtual objects, and the objective reality of natural kinds.

A sophisticated and original introduction to the philosophy of quantum mechanics from one of the world’s leading philosophers of physics In this book, Tim Maudlin, one of the world’s leading philosophers of physics, offers a sophisticated, original introduction to the philosophy of quantum mechanics. The briefest, clearest, and most refined account of his influential approach to the subject, the book will be invaluable to all students of philosophy and physics. Quantum mechanics holds a unique place in the history of physics. It has produced the most accurate predictions of any scientific theory, but, more astonishing, there has never been any agreement about what the theory implies about physical reality. Maudlin argues that the very term “quantum theory” is a misnomer. A proper physical theory should clearly describe what is there and what it does—yet standard textbooks present quantum mechanics as a predictive recipe in search of a physical theory. In contrast, Maudlin explores three proper theories that recover the quantum predictions: the indeterministic wavefunction collapse theory of Ghirardi, Rimini, and Weber; the deterministic particle theory of deBroglie and Bohm; and the conceptually challenging Many Worlds theory of Everett. Each offers a radically different proposal for the nature of physical reality, but Maudlin shows that none of them are what they are generally taken to be.

The only book that addresses Cartwright's undoubted influence on the study of the philosophy of science. This critical assessment contains contributions from Cartwright's champions and critics, including leading scholars in the field such as Ronald N. Giere and Paul Teller.

The first interdisciplinary investigation of the cultural context of enactive embodiment, offering perspectives that range from the neurophilosophical to the anthropological. Recent accounts of cognition attempt to overcome the limitations of traditional cognitive science by reconceiving cognition as enactive and the cognizer as an embodied being who is embedded in biological, psychological, and cultural contexts. Cultural forms of sense-making constitute the shared world, which in turn is the origin and place of cognition. This volume is the first interdisciplinary collection on the cultural context of embodiment, offering perspectives that range from the neurophilosophical to the anthropological. The book brings together new contributions by some of the most renowned scholars in the field and the latest results from up-and-coming researchers. The contributors explore conceptual foundations, drawing on work by Husserl, Merleau-Ponty, and Sartre, and respond to recent critiques. They consider whether there is something in the self that precedes intersubjectivity and inquire into the relation between culture and consciousness, the nature of shared meaning and social understanding, the social dimension of shame, and the nature of joint affordances. They apply the notion of radical enactive cognition to evolutionary anthropology, and examine the concept of the body in relation to culture in light of studies in such fields as phenomenology, cognitive neuroscience, psychology, and psychopathology. Through such investigations, the book breaks ground for the study of the interplay of embodiment, enaction, and culture.

Quantum theory is perhaps our best confirmed theory for a description of the physical properties of nature. On top of demonstrating great empirical effectiveness, many technological developments in the 20th century (such as the interpretation of the periodic table of elements, CD players, holograms, and quantum state teleportation) were only made possible with Quantum theory.Despite its success in the past decades, even today it still remains without a universally accepted interpretation.This book provides an interdisciplinary perspective on the question; 'What is Quantum Mechanics talking about?', a question which continues to be one of the most fascinating and important questions in science.Using an interdisciplinary approach to foundational problems in Quantum Mechanics (QM), ranging from philosophical questions about the interpretation of QM to technical problems in quantum computation, this book explores quantum mechanics from different perspectives (physical, logical, philosophical and mathematical), by researchers from Europe, North America, and South America.

The recovery of Dante's metaphysics-which are very different from our own-is essential, argues Christian Moevs, if we are to resolve what has been called 'the central problem in the interpretation of the Comedy.' That problem is what to make of the Comedy's claim to the status of revelation, vision, or experiential record - as something more than imaginative literature. In this book Moevs offers the first sustained treatment of the metaphysical picture that grounds and motivates the Comedy, and the relation between those metaphysics and Dante's poetics. Moevs arrives at the radical conclusion that Dante believed that all of what we perceive as reality, the spatio-temporal world, is in fact a creation or projection of conscious being. Armed with this new understanding, Moevs is able to shed light on a series of perennial issues in the interpretation of the Comedy.
