Gauge theories have provided our most successful representations of the fundamental forces of nature. How, though, do such representations work? Interpretations of gauge theory aim to answer this question. Through understanding how a gauge theory's representations work, we are able to say what kind of world our gauge theories reveal to us.
A gauge theory's representations are mathematical structures. These may be transformed among themselves while certain features remain the same. Do the representations related by such a gauge transformation merely offer alternative ways of representing the very same situation? If so, then gauge symmetry is a purely formal property since it reflects no corresponding symmetry in nature.
Gauging What's Real describes the representations provided by gauge theories in both classical and quantum physics. Richard Healey defends the thesis that gauge transformations are purely formal symmetries of almost all the classes of representations provided by each of our theories of fundamental forces. He argues that evidence for classical gauge theories of forces (other than gravity) gives us reason to believe that loops rather than points are the locations of fundamental properties. In addition to exploring the prospects of extending this conclusion to the quantum gauge theories of the Standard Model of elementary particle physics, Healey assesses the difficulties faced by attempts to base such ontological conclusions on the success of these theories.

Simon Evnine examines various epistemic aspects of what it is to be a person. Persons are defined as finite beings that have beliefs, including second-order beliefs about their own and others' beliefs, and are agents, capable of making long-term plans. It is argued that for any being meeting these conditions, a number of epistemic consequences obtain. First, all such beings must have certain logical concepts and be able to use them in certain ways. Secondly, there are at least two principles governing belief that it is rational for persons to satisfy and are such that nothing can be a person at all unless it satisfies them to a large extent. These principles are that one believe the conjunction of one's beliefs and that one treat one's future beliefs as, by and large, better than one's current beliefs. Thirdly, persons both occupy epistemic points of view on the world and show up within those views. This makes it impossible for them to be completely objective about their own beliefs. Ideals of rationality that require such objectivity, while not necessarily wrong, are intrinsically problematic for persons. This "aspectual dualism" is characteristic of treatments of persons in the Kantian tradition. In sum, these epistemic consequences support a traditional view of the nature of persons, one in opposition to much recent theorizing.

Genealogies of Speculation looks to break the impasse between the innovations of speculative thought and the dominant strands of 20th century anti-foundationalist philosophy. Challenging emerging paradigms of philosophical history, this text re-evaluates different theoretical and political traditions such as feminism, literary theory, social geography and political theory after the speculative turn in philosophy. With contributions from leading writers in contemporary thought this book is a crucial resource for studying cultural and art-theory and continental philosophy.

Modal realism says that non-actual possible worlds and individuals are as real as the actual world and individuals. Takashi Yagisawa defends modal realism of a variety different from David Lewis's theory. The notion of reality is left primitive and sharply distinguished from that of existence, which is proposed as a relation between a thing and a domain. Worlds are postulated as modal indices for truth on a par with times, which are temporal indices for truth. Ordinary individual objects are conceived as being extended in spatial, temporal, and modal dimensions, and their transworld identity is explicated by the closest-continuer theory. Impossible worlds and individuals are postulated and used to provide accounts of propositions, belief sentences, and fictional discourse.

Antonia Lolordo presents an original interpretation of John Locke's conception of moral agency-one that has implications both for his metaphysics and for the foundations of his political theory. Locke denies that species boundaries exist independently of human convention, holds that the human mind may be either an immaterial substance or a material one to which God has superadded the power of thought, and insists that animals possess the ability to perceive, will, and even reason-indeed, in some cases to reason better than humans. Thus, he eliminates any sharp distinction between humans and the rest of the animal kingdom. However, in his ethical and political work Locke assumes that there is a sharp distinction between moral agents and other beings. He thus needs to be able to delineate the set of moral agents precisely, without relying on the sort of metaphysical and physical facts his predecessors appealed to. Lolordo argues that for Locke, to be a moral agent is simply to be free, rational, and a person. Interpreting the Lockean metaphysics of moral agency in this way helps us to understand both Locke's over-arching philosophical project and the details of his accounts of liberty, personhood, and rationality.

Weakness of will, the phenomenon of acting contrary to one's own better judgment, has remained a prominent discussion topic of philosophy. The history of this discussion in ancient, medieval, and modern times has been outlined in many studies. Weakness of Will in Renaissance and ReformationThought is, however, the first book to cover the fascinating source materials on weakness of will between 1350 and 1650. In addition to considering the work of a broad range of Renaissance authors (including Petrarch, Donato Acciaiuoli, John Mair, and Francesco Piccolomini), Risto Saarinen explores the theologically coloured debates of the Reformation period, such as those provided by Martin Luther, Philip Melanchthon, John Calvin, and Lambert Daneau. He goes on to discuss the impact of these authors on prominent figures of early modernity, including Shakespeare, Descartes, Spinoza, and Leibniz.
While most of the historical research on weakness of will has focused on the reception history of Aristotle's Nicomachean Ethics, Saarinen pays attention to the Platonic and Stoic discussions and their revival during the Renaissance and the Reformation. He also shows the ways in which Augustine's discussion of the divided will is intertwined with the Christian reception of ancient Greek ethics, and argues that the theological underpinnings of early modern authors do not rule out weakness of will, but transform the philosophical discussion and lead it towards new solutions.

A Critical Introduction to Fictionalism provides a clear and comprehensive understanding of an important alternative to realism. Drawing on questions from ethics, the philosophy of religion, art, mathematics, logic and science, this is a complete exploration of how fictionalism contrasts with other non-realist doctrines and motivates influential fictionalist treatments across a range of philosophical issues. Defending and criticizing influential as well as emerging fictionalist approaches, this accessible overview discuses physical objects, universals, God, moral properties, numbers and other fictional entities. Where possible it draws general lessons about the conditions under which a fictionalist treatment of a class of items is plausible. Distinguishing fictionalism from other views about the existence of items, it explains the central features of this key metaphysical topic. Featuring a historical survey, definitions of key terms, characterisations of important subdivisions, objections and problems for fictionalism, and contemporary fictionalist treatments of several issues, A Critical Introduction to Fictionalism is a valuable resource for students of metaphysics as well as students of philosophical methodology. It is the only book of its kind.

The Logic Manual is a clear and concise introduction to logic for beginning philosophy students. It offers a complete introductory course, guiding the reader carefully through the topics in logic that are most important for the study of philosophy. It covers propositional and predicate logic with and without identity. It includes an account of the semantics of these languages including definitions of truth and satisfaction. Natural deduction is used as a proof system. Volker Halbach introduces the essential concepts through examples and informal explanations as well as through abstract definitions.
The Logic Manual provides the best entry to the general abstract way of thinking about language, logic, and semantics which is characteristic of contemporary philosophy. Exercises, examples, and sample examination papers are provided on an accompanying website.

Anthropomorphism - the projection of the human form onto the every aspect of the world - closely relates to early modern notions of analogy and microcosm. What had been construed in Antiquity as a ready metaphor for the order of creation was reworked into a complex system relating the human body to the body of the world. Numerous books and images - cosmological diagrams, illustrated treatises of botany and zoology, maps, alphabets, collections of ornaments, architectural essays - are entirely constructed on the anthropomorphic analogy. Exploring the complexities inherent in such work, the interdisciplinary essays in this volume address how the anthropomorphic model is fraught with contradictions and tensions, between magical and rational, speculative and practical thought. Contributors include Pamela Brekka, Anne-Laure van Bruaene, Ralph Dekoninck, Agnes Guiderdoni, Christopher P. Heuer, Sarah Kyle, Walter S. Melion, Christina Normore, Elizabeth Petcu, Bertrand Prevost, Bret Rothstein, Paul Smith, Miya Tokumitsu, Michel Weemans, and Elke Werner.

Alain Badiou has claimed that Quentin Meillassoux's book After Finitude (Bloomsbury, 2008) "opened up a new path in the history of philosophy." And so, whether you agree or disagree with the speculative realism movement, it has to be addressed. Lacanian Realism does just that. This book reconstructs Lacanian dogma from the ground up: first, by unearthing a new reading of the Lacanian category of the real; second, by demonstrating the political and cultural ingenuity of Lacan's concept of the real, and by positioning this against the more reductive analyses of the concept by Slavoj Zizek, Alain Badiou, Saul Newman, Todd May, Joan Copjec, Jacques Ranciere, and others, and; third, by arguing that the subject exists intimately within the real. Lacanian Realism is an imaginative and timely exploration of the relationship between Lacanian psychoanalysis and contemporary continental philosophy.

George Berkeley notoriously claimed that his immaterialist metaphysics was not only consistent with common sense but that it was also integral to its defense. Roberts argues that understanding the basic connection between Berkeley's philosophy and common sense requires that we develop a better understanding of the four principle components of Berkeley's positive metaphysics: The nature of being, the divine language thesis, the active/passive distinction, and the nature of spirits.
Roberts begins by focusing on Berkeley's view of the nature of being. He elucidates Berkeley's view on Locke and the Cartesians and by examining Berkeley's views about related concepts such as unity and simplicity. From there he moves on to Berkeley's philosophy of language arguing that scrutiny of the famous "Introduction" to the Principles of Human Knowledge reveals that Berkeley identified the ideational theory of meaning and understanding as the root cause of some of the worst of man's intellectual errors, not "abstract ideas." Abstract ideas are, rather, the most debilitating symptom of this underlying ailment. In place of the ideational theory, Berkeley defends a rudimentary "use theory" of meaning. This understanding of Berkeley's approach to semantics is then applied to the divine language thesis and is shown to have important consequences for Berkeley's pragmatic approach to the ontology of natural objects and for his approach to our knowledge of, and relation to other minds, including God's. Turning next to Berkeley's much aligned account of spirits, the author defends the coherence of Berkeley's view of spirits by way of providing an interpretation of the active/passive distinction as marking anormative distinction and by focusing on the role that divine language plays in letting Berkeley identify the soul with the will. With these four principles of Berkeley's philosophy in hand, he then returns to the topic of common sense and offers a defense of Berkeley's philosophy as built upon and expressive of the deepest metaphysical commitments of mainstream Christianity.
Roberts' reappraisal of this important figure should appeal to all historians of philosophy as well as scholars in metaphysics and philosophy of language.

Kathrin Koslicki offers an analysis of ordinary material objects, those material objects to which we take ourselves to be committed in ordinary, scientifically informed discourse. She focuses particularly on the question of how the parts of such objects are related to the wholes which they compose.
Many philosophers today find themselves in the grip of an exceedingly deflationary conception of what it means to be an object. According to this conception, any plurality of objects, no matter how disparate or gerrymandered, itself composes an object, even if the objects in question fail to exhibit interesting similarities, internal unity, cohesion, or causal interaction amongst each other.
This commitment to initially counterintuitive objects follows from the belief that no principled set of criteria is available by means of which to distinguish intuitively gerrymandered objects from commonsensical ones; the project of this book is to persuade the reader that systematic principles can be found by means of which composition can be restricted, and hence that we need not embrace this deflationary approach to the question of what it means to be an object.
To this end, a more full-blooded neo-Aristotelian account of parthood and composition is developed according to which objects are structured wholes: it is integral to the existence and identity of an object, on this conception, that its parts exhibit a certain manner of arrangement. This structure-based conception of parthood and composition is explored in detail, along with some of its historical precursors as well as some of its contemporary competitors.

Our experience of objects (and consequently our theorizing about them) is very rich. We perceive objects as possessing individuation conditions. They appear to have boundaries in space and time, for example, and they appear to move independently of a background of other objects or a landscape. In Ontology Without Boundaries Jody Azzouni undertakes an analysis of our concept of object, and shows what about that notion is truly due to the world and what about it is a projection onto the world of our senses and thinking. Location and individuation conditions are our product: there is no echo of them in the world. Features, the ways that objects seem to be, aren't projections. Azzouni shows how the resulting austere metaphysics tames a host of ancient philosophical problems about constitution ("Ship of Theseus," "Sorities"), as well as contemporary puzzles about reductionism. In addition, it's shown that the same sorts of individuation conditions for properties, which philosophers use to distinguish between various kinds of odd abstracta-universals, tropes, and so on, are also projections. Accompanying our notion of an object is a background logic that makes cogent ontological debate about anything from Platonic objects to Bigfoot. Contemporary views about this background logic ("quantifier variance") make ontological debate incoherent. Azzouni shows how a neutral interpretation of quantifiers and quantifier domains makes sense of both philosophical and pre-philosophical ontological debates. Azzouni also shows how the same apparatus makes sense of our speaking about a host of items-Mickey Mouse, unicorns, Martians-that nearly all of us deny exist. It's allowed by what Azzouni shows about the background logic of our ontological debates, as well as the semantics of the language of those debates that we can disagree over the existence of things, like unicorns, without that background logic and semantics forcing ontological commitments onto speakers that they don't have.

Arguments that ordinary inanimate objects such as tables and chairs, sticks and stones, simply do not exist have become increasingly common and increasingly prominent. Some are based on demands for parsimony or for a non-arbitrary answer to the special composition question; others arise from prohibitions against causal redundancy, ontological vagueness, or co-location; and others still come from worries that a common sense ontology would be a rival to a scientific one. Until now, little has been done to address these arguments in a unified and systematic way. Ordinary Objects is designed to fill this gap, demonstrating that the mistakes behind all of these superficially diverse eliminativist arguments may be traced to a common source. It aims to develop an ontology of ordinary objects subject to no such problems, providing perhaps the first sustained defense of a common sense ontology in two generations. The work done along the way addresses a number of major issues in philosophy of language and metaphysics, contributing to debates about analyticity, identity conditions, co-location and the grounding problem, vagueness, overdetermination, parsimony, and ontological commitment. In the end, the most important result of addressing these eliminativist arguments is not merely avoiding their conclusions; examining their failings also gives us reason to suspect that many apparent disputes in ontology are pseudo-debates. For it brings into question widely-held assumptions about which uses of metaphysical principles are appropriate, which metaphysical demands are answerable, and how we should go about addressing such fundamental questions as "What exists?". As a result, the work of Ordinary Objects promises to provide not only the route to a reflective understanding of our unreflective common-sense view, but also a better understanding of the proper methods and limits of metaphysics. "Ordinary Objects is well worth reading because it sheds new light on how to preserve the credibility of familiar things."-Marianne Djuth, The Review of Metaphysics "In Ordinary Objects , Amie Thomasson mounts a spirited and vigorous defense of the reality of ordinary objects."-Terry Horgan, Times Literary Supplement "Ordinary Objects is a fine book.... [Thomasson] writes insightfully and persuasively, and she has a realistic view of what metaphysical arguments can and cannot demonstrate... she approaches metaphysical theorizing more systematically than many other recent writers, drawing attention to the ways in which questionable assumptions in one area of philosophy are undergirding seemingly powerful arguments in another. Everyone working in metaphysics should make time for this volume."-R. W. Fischer, Metaphilosophy "In Ordinary Objects , Thomasson pursues an integrated conception of ontology and metaontology. In ontology, she defends the existence of shoes, ships, and other ordinary objects. In metaontology, she defends a deflationary view of ontological inquiry, designed to suck the air out of arguments against ordinary objects. The result is an elegant and insightful defense of a common sense worldview."-Jonathan Schaffer, Philosophical Books "Amie Thomasson has written a lovely book which is certain to irritate many professional metaphysicians. But it is not just irritating: it is challenging...This book would be good supplementary text for upper-level metaphysics classes or seminars in which the sorts of arguments to which Thomasson replies are also read."-Alan Sidelle, The Philosophical Quarterly

According to two-dimensional semantics, the meaning of an expression involves two different "dimensions": one dimension involves reference and truth-conditions of a familiar sort, while the other dimension involves the way that reference and truth-conditions depend on the external world (for example, reference and truth-conditions might be held to depend on which individuals and substances are present in the world, or on which linguistic conventions are in place). A number of different two-dimensional frameworks have been developed, and these have been applied to a number of fundamental problems in philosophy: the nature of communication, the relation between the necessary and the a priori, the role of context in assertion, Frege's distinction between sense and reference, the contents of thought, and the mind-body problem. Manuel Garcia-Carpintero and Josep Macia present a selection of new essays by an outstanding international team, shedding fresh light both on foundational issues regarding _ two-dimensional semantics and on its specific applications. The volume will be the starting-point for future work on this approach to issues in philosophy of language, _ epistemology, and metaphysics. _

Deleuze's concept of 'becoming' provides the key to his notoriously complex metaphysics, yet it has not been systematized until now. Bankston tracks the concept of becoming and its underlying temporal processes across Deleuze's writings, arguing that expressions of becoming(s) appear in two modes of temporality: an appropriation of Nietzsche's eternal return (the becoming of the event), and Bergsonian duration (the becoming of sensation). Overturning the criticisms launched by Zizek and Badiou, with conceptual encounters between Bergson, Nietzsche, Leibniz, Borges, Klossowski, and Proust, the newly charted concept of double becoming provides a roadmap to the totality of Deleuze's philosophy. Bankston systematizes Deleuze's multi-mirrored universe where form and content infinitely refract in a vital kaleidoscope of becoming.

Responsibility, Complexity, and Abortion: Toward a New Image of Ethical Thought draws from feminist theory, post-structuralist theory, and complexity theory to develop a new set of ethical concepts for broaching the thinking challenges that attend the experience of unwanted pregnancy. Author Karen Houle does not only argue for these concepts; she enacts a method for working with them, a method that brackets the tendency to take positions and to think that position-taking is what ethical analysis involves. This book thus provides concrete evidence of a theoretically-grounded, compassionate way that people in all walks of life, academic or otherwise, could come to a better understanding of, and more complex relationship to, difficult ethical issues. On the one hand, this is a meta-ethical book about how people can conceive and communicate moral ideas in ways that are more constructive than position-taking; on the other hand, it is also a book about abortion. It testifies from a first-person female perspective about the life-long complexity that attends fertility, sexuality and reproduction. But it does not do so in order to ratify abortion as a woman's issue or a private matter or as feminist work. Rather, its aim is to excavate the ethical richness of the situation of unwanted pregnancy showing that it connects to everyone, affects everyone, and thus gives everyone something unique and new to think.

The concept of causation is fundamental to ascribing moral and legal responsibility for events. Yet the relationship between causation and responsibility remains unclear. What precisely is the connection between the concept of causation used in attributing responsibility and the accounts of causal relations offered in the philosophy of science and metaphysics? How much of what we call causal responsibility is in truth defined by non-causal factors? This book argues that much of the legal doctrine on these questions is confused and incoherent, and offers the first comprehensive attempt since Hart and Honore to clarify the philosophical background to the legal and moral debates.
The book first sets out the place of causation in criminal and tort law and then outlines the metaphysics presupposed by the legal doctrine. It then analyses the best theoretical accounts of causation in the philosophy of science and metaphysics, and using these accounts criticizes many of the core legal concepts surrounding causation - such as intervening causation, forseeability of harm and complicity. It considers and rejects the radical proposals to eliminate the notion of causation from law by using risk analysis to attribute responsibility. The result of the analysis is a powerful argument for revising our understanding of the role played by causation in the attribution of legal and moral responsibility.

Charles E. Snyder considers the New Academy's attacks on Stoic epistemology through a critical re-assessment of the 3rd century philosopher, Arcesilaus of Pitane. Arguing that the standard epistemological framework used to study the ancient Academy ignores the metaphysical dimensions at stake in Arcesilaus's critique, Snyder explores new territory for the historiography of Stoic-Academic debates in the early Hellenistic period. Focusing on the dispute between the Old and New Academy, Snyder reveals the metaphysical dimensions of Arcesilaus' arguments as essential to grasping what is innovative about the so-called New Academy. Resisting the partiality for epistemology in the historical reconstructions of ancient philosophy, this book defends a new philosophical framework that re-positions Arcesilaus' attack on the early Stoa as key to his deviation from the metaphysical foundations of both Stoic and Academic virtue ethics. Drawing on a wide range of scholarship on Hellenistic philosophy in French, Italian, and German, Beyond Hellenistic Epistemology builds bridges between analytical and continental approaches to the historiography of ancient philosophy, and makes an important and disruptive contribution to the literature.
