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In this book, Steven Horst argues that this whole conversation is based on assumptions left over from an outdated philosophy of science.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 inphilosophy 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 is intended as an introduction to the philosophical problems of space and time, suitable for any reader who has an interest in the nature of the universe and who has a secondary-school knowledge of physics and mathematics. In particular, it is hoped that the book may find a use in philosophy departments and physics departments within universities and other tertiary institutions. The attempt is always to introduce the problems from a twentieth-century point of view. It is preferable to introduce the history of the topic if and when that history becomes relevant to the development and solution of the problems, rather than to introduce a problem that was of importance in some previous age and to trace the development of it down the years.

While it is generally accepted that animal welfare matters morally, it is less clear how to morally evaluate the ending of an animal's life. It seems to matter for the animal whether it experiences pain or pleasure, or enjoyment or suffering. But does it also matter for the animal whether it lives or dies? Is a longer life better for an animal than a shorter life? If so, under what conditions is this so, and why is this the case? Is it better for an animal to live rather than never to be born at all? The Ethics of Killing Animals addresses these value-theoretical questions about animal life, death and welfare. It also discusses whether and how answers to these questions are relevant for our moral duties towards animals. Is killing animals ever morally acceptable and, if so, under what conditions? Do animals have moral rights, such as the right to life and should they be accorded legal rights? How should our moral duties towards animals inform our individual behavior and policy-making? This volume presents a collection of contributions from major thinkers in ethics and animal welfare, with a special focus on the moral evaluation of killing animals.

This collection of essays by liberal and feminist philosophers addresses the question of whether marriage reform ought to stop with same-sex marriage. Some philosophers have recently argued that marriage is illiberal and should be abolished or radically reformed to include groups and non-romantic friendships. In response, Simon May argues that marriage law can be justified without an illiberal appeal to an ideal relationship type, and Ralph Wedgwood argues that the liberal values which justify same-sex marriage do not justify further extension. Other authors argue for new legal forms for intimate relationships. Marriage abolitionist Clare Chambers argues that piecemeal directives rather than relationship contracts should replace marriage, and Samantha Brennan and Bill Cameron argue for separating marriage and parenting, with parenting rather than marriage becoming, legally and socially, the foundation of the family. Elizabeth Brake argues for a non-hierarchical friendship model for marriage. Peter de Marneffe argues that polygamy should be decriminalized, but that the liberal state need not recognize it, while Laurie Shrage argues that polygamy could be legally structured to protect privacy and equality. Dan Nolan argues for temporary marriage as a legal option, while Anca Gheaus argues that marital commitments are problematic instruments for securing the good of romantic and sexual love. Taken together, these essays challenge contemporary understandings of marriage and the state's role in it.
