Beyond Reduction

Contemporary philosophers of mind tend to assume that the world of nature can be reduced to basic physics. Yet there are features of the mind consciousness, intentionality, normativity that do not seem to be reducible to physics or neuroscience. This explanatory gap between mind and brain has thus been a major cause of concern in recent philosophy of mind. Reductionists hold that, despite all appearances, the mind can be reduced to the brain. Eliminativists hold that it cannot, and that this implies that there is something illegitimate about the mentalistic vocabulary. Dualists hold that the mental is irreducible, and that this implies either a substance or a property dualism. Mysterian non-reductive physicalists hold that the mind is uniquely irreducible, perhaps due to some limitation of our self-understanding. In this book, Steven Horst argues that this whole conversation is based on assumptions left over from an outdated philosophy of science. While reductionism was part of the philosophical orthodoxy fifty years ago, it has been decisively rejected by philosophers of science over the past thirty years, and for good reason. True reductions are in fact exceedingly rare in the sciences, and the conviction that they were there to be found was an artifact of armchair assumptions of 17th century Rationalists and 20th century Logical Empiricists. The explanatory gaps between mind and brain are far from unique. In fact, in the sciences it is gaps all the way down.And if reductions are rare in even the physical sciences, there is little reason to expect them in the case of psychology. Horst argues that this calls for a complete re-thinking of the contemporary problematic in philosophy of mind. Reductionism, dualism, eliminativism and non-reductive materialism are each severely compromised by post-reductionist philosophy of science, and philosophy of mind is in need of a new paradigm. Horst suggests that such a paradigm might be found in Cognitive Pluralism: the view that human cognitive architecture constrains us to understand the world through a plurality of partial, idealized, and pragmatically-constrained models, each employing a particular representational system optimized for its own problem domain. Such an architecture can explain the disunities of knowledge, and is plausible on evolutionary grounds.

This book highlights strategies for poverty reduction in developing countries, with emphasis on the power of the market mechanism and vigor of the private sector, focusing ODA on a few longer term challenges and leveraging advances in technology to the fullest, and underlining the importance of human rights and security.

While much attention has been devoted to the conflicts between religion and science in the modern age, less rarely has sufficient attention been devoted to the complex interplay between religion, science and philosophy. This book offers a set of wide-ranging essays in which the interplay between all these three is the explicit focus of attention. The essays reflect a desire to think of this interplay in terms other than conflict and reduction. The book also represents a pluralism of approaches to reflection on this interplay. Part I represents a more idealistic orientation in which religion, philosophy and science are seen to enjoy a complementarity. Part II formulates the interplay more from the standpoint of process philosophy. Part III explores the issue with primary emphasis on the contributions of science. In Part IV the essays reflect a desire to take the religious on its own terms, and explore the interplay with philosophy and science with the proper seriousness solicited by these terms.

This volume investigates the notion of reduction. Building on the idea that philosophers employ the term ‘reduction’ to reconcile diversity and directionality with unity, without relying on elimination, the book offers a powerful explication of an “ontological”, notion of reduction the extension of which is (primarily) formed by properties, kinds, individuals, or processes. It argues that related notions of reduction, such as theory-reduction and functional reduction, should be defined in terms of this explication. Thereby, the book offers a coherent framework, which sheds light on the history of the various reduction debates in the philosophy of science and in the philosophy of mind, and on related topics such as reduction and unification, the notion of a scientific level, and physicalism. The book takes its point of departure in the examination of a puzzle about reduction. To illustrate, the book takes as an example the reduction of water. If water reduces to H2O, then water is identical to H2O – thus we get unity. Unity does not come at the price of elimination – claiming that water reduces to H2O, we do not thereby claim that there is no water. But what about diversity and directionality? Intuitively, there should be a difference between water and H2O, such that we get diversity. This is required for there to be directionality: in a sense, if water reduces to H2O, then H2O is prior to, or more basic than water. At least, if water reduces to H2O, then H2O does not reduce to water. But how can this be, if water is identical to H2O? The book shows that the application of current models of reduction does not solve this puzzle, and proposes a new coherent definition, according to which unity is tied to identity, diversity is descriptive in nature, and directionality is the directionality of explanation.

This complete introduction to the use of modern ray tracing techniques in plasma physics describes the powerful mathematical methods generally applicable to vector wave equations in non-uniform media, and clearly demonstrates the application of these methods to simplify and solve important problems in plasma wave theory. Key analytical concepts are carefully introduced as needed, encouraging the development of a visual intuition for the underlying methodology, with more advanced mathematical concepts succinctly explained in the appendices, and supporting Matlab and Raycon code available online. Covering variational principles, covariant formulations, caustics, tunnelling, mode conversion, weak dissipation, wave emission from coherent sources, incoherent wave fields, and collective wave absorption and emission, all within an accessible framework using standard plasma physics notation, this is an invaluable resource for graduate students and researchers in plasma physics.

This book examines the dynamics of attitudinal change from the individual to the group levels and proposes a proactive analytical framework.

While many comprehensive texts have been written on the treatment of breast cancer, the most common cancer among women, there are relatively few which cover in depth the prevention and early detection of the disease. The goal of this work is to present what experts in the ?eld feel is the current knowledge and future direction of breast cancer prevention and early detection. We begin Part I of the book with a review of risk factors, both genetic and environmental. We next review progress in the use of chemoprevention. Notably, chemoprevention risk reduction studies have led to FDA approval of two medications which measurably reduce disease incidence among women at increased risk, although with some risk of treatment related side effects. Newer agents in the pipeline, which may also reduce risk among normal risk women, are also discussed. Surgical risk reducing strategies complete the section on prevention, including both the bene?ts and downsides to this more aggressive approach. Even with aggressive prevention strategies, some women will develop breast cancer. For these women, early detection is critical to minimize disease spread and maximize long term survival. Part II of this book reviews current and upcoming approaches to early detection. Imaging strategies, including mammography, breast ultrasound, MRI, and PET imaging are reviewed. The potential for molecular tumor targeting to detect disease prior to the formation of a mass visible by anatomic imaging is presented.
