This revised and considerably expanded 2nd edition brings together a wide range of topics, including modal, tense, conditional, intuitionist, many-valued, paraconsistent, relevant, and fuzzy logics. Part 1, on propositional logic, is the old Introduction, but contains much new material. Part 2 is entirely new, and covers quantification and identity for all the logics in Part 1. The material is unified by the underlying theme of world semantics. All of the topics are explained clearly using devices such as tableau proofs, and (...) their relation to current philosophical issues and debates are discussed. Students with a basic understanding of classical logic will find this book an invaluable introduction to an area that has become of central importance in both logic and philosophy. It will also interest people working in mathematics and computer science who wish to know about the area. (shrink)

Whether considering vegetarianism, women's rights, or the "humanity" of pets, this book goes to the heart of the question of why all animals matter.

The moral domain is broader than the empathy and justice concerns assessed by existing measures of moral competence, and it is not just a subset of the values assessed by value inventories. To fill the need for reliable and theoretically grounded measurement of the full range of moral concerns, we developed the Moral Foundations Questionnaire on the basis of a theoretical model of 5 universally available sets of moral intuitions: Harm/Care, Fairness/Reciprocity, Ingroup/Loyalty, Authority/Respect, and Purity/Sanctity. We present evidence for the (...) internal and external validity of the scale and the model, and in doing so we present new findings about morality: Comparative model fitting of confirmatory factor analyses provides empirical justification for a 5-factor structure of moral concerns; convergent/discriminant validity evidence suggests that moral concerns predict personality features and social group attitudes not previously considered morally relevant; and we establish pragmatic validity of the measure in providing new knowledge and research opportunities concerning demographic and cultural differences in moral intuitions. These analyses provide evidence for the usefulness of Moral Foundations Theory in simultaneously increasing the scope and sharpening the resolution of psychological views of morality. (shrink)

This is a philosophical investigation of the nature of the limits of thought. Drawing on recent developments in the field of logic, Graham Priest shows that the description of such limits leads to contradiction, and argues that these contradictions are in fact veridical. Beginning with an analysis of the way in which these limits arise in pre-Kantian philosophy, Priest goes on to illustrate how the nature of these limits was theorised by Kant and Hegel. He offers new interpretations of (...) Berkeley's master argument for idealism and Kant on the antimonies. He explores the paradoxes of self reference, and provides a unified account of the structure of such paradoxes. The book concludes by tracing the theme of the limits of thought in modern philosophy of language, including discussions of the ideas of Wittgenstein and Derrida. (shrink)

The article looks at the structure of impossible worlds, and their deployment in the analysis of some intentional notions. In particular, it is argued that one can, in fact, conceive anything, whether or not it is impossible. Thus a semantics of conceivability requires impossible worlds.

In this book, Graham Oppy examines arguments for and against the existence of God. He shows that none of these arguments is powerful enough to change the minds of reasonable participants in debates on the question of the existence of God. His conclusion is supported by detailed analyses of the arguments as well as by the development of a theory about the purpose of arguments and the criteria that should be used in judging whether or not arguments are successful. (...) Oppy discusses the work of a wide array of philosophers, including Anselm, Aquinas, Descartes, Locke, Leibniz, Kant, Hume and, more recently, Plantinga, Dembski, White, Dawkins, Bergman, Gale and Pruss.

Graham Priest presents an exploration of the development of Buddhist metaphysics, which is viewed through the lens of the catuskoti. In its earliest and simplest form this is a logical/metaphysical principle which says that every claim is true, false, both, or neither; but Priest shows how the principle itself evolves as the metaphysics develops.

The Law of Non-Contradiction - that no contradiction can be true - has been a seemingly unassailable dogma since the work of Aristotle, in Book G of the Metaphysics. It is an assumption challenged from a variety of angles in this collection of original papers. Twenty-three of the world's leading experts investigate the 'law', considering arguments for and against it and discussing methodological issues that arise whenever we question the legitimacy of logical principles. The result is a balanced inquiry into (...) a venerable principle of logic, one that raises questions at the very centre of logic itself. The aim of this volume is to present a comprehensive debate about the Law of Non-Contradiction, from discussions as to how the law is to be understood, to reasons for accepting or re-thinking the law, and to issues that raise challenges to the law, such as the Liar Paradox, and a 'dialetheic' resolution of that paradox. The editors contribute an introduction which surveys the issues and serves to frame the debate, and a useful bibliography offering a guide to further reading. This volume will be of interest to anyone working on philosophical logic, and to anyone who has ever wondered about the status of logical laws and about how one might proceed to mount arguments for or against them.

This book is an exploration of philosophical questions about infinity. Graham Oppy examines how the infinite lurks everywhere, both in science and in our ordinary thoughts about the world. He also analyses the many puzzles and paradoxes that follow in the train of the infinite. Even simple notions, such as counting, adding and maximising present serious difficulties. Other topics examined include the nature of space and time, infinities in physical science, infinities in theories of probability and decision, the nature (...) of part/whole relations, mathematical theories of the infinite, and infinite regression and principles of sufficient reason.

This book is a unique contribution to the philosophy of religion. It offers a comprehensive discussion of one of the most famous arguments for the existence of God: the ontological argument. The author provides and analyses a critical taxonomy of those versions of the argument that have been advanced in recent philosophical literature, as well as of those historically important versions found in the work of St Anselm, Descartes, Leibniz, Hegel and others. A central thesis of the book is that (...) ontological arguments have no value in the debate between theists and atheists. There is a detailed review of the literature on the topic (separated from the main body of the text) and a very substantial bibliography, making this volume an indispensable resource for philosophers of religion and others interested in religious studies.

Many people hold that there is a distinctive notion of metaphysical necessity. In this paper I explain why I am skeptical about the view. I examine the sorts of considerations that are adduced for it, and argue that they meet equal and opposite considerations.

We find our way in the world partly by means of the discriminatory power of our emotions. The gut sense that something is repugnant or unsavory—the sort of feeling that many now have about various forms of biotechnology—sometimes turns out to be rooted in articulable and legitimate objections, which with time can be spelled out, weighed, and either endorsed or dismissed. But we ought not dismiss the emotional response at the outset as “mere feeling.”.

This is a revised and updated edition of Graham Nerlich's classic book The Shape of Space. It develops a metaphysical account of space which treats it as a real and concrete entity. In particular, it shows that the shape of space plays a key explanatory role in space and spacetime theories. Arguing that geometrical explanation is very like causal explanation, Professor Nerlich prepares the ground for philosophical argument, and, using a number of novel examples, investigates how different spaces would (...) affect perception differently. This leads naturally to conventionalism as a non-realist metaphysics of space, an account which Professor Nerlich criticises, rejecting its Kantian and positivistic roots along with Reichenbach's famous claim that even the topology of space is conventional. He concludes that there is, in fact, no problem of underdetermination for this aspect of spacetime theories, and offers an extensive discussion of the relativity of motion. (shrink)

The paper argues for realism in quantum mechanics. Specifically, the formalism of quantum mechanics should be understood as giving a complete description of quantum situations. When it is understood in this way, traditional primary properties of matter can be seen as similar to traditional secondary properties, though at a different level.

What is culture? What can we learn from art, architecture, and fashion about how people relate? Can cultures embody ethical and moral ideals? These are just some of the questions addressed in this book on the cultural philosophy of three preeminent Japanese philosophers of the early twentieth century, Nishida Kitarō, Watsuji Tetsurō and Kuki Shūzō.

Hylomorphism is the theory that objects are composites of form and matter. Recently it has been argued that form is structure, or the arrangement of an object's parts. This paper shows that the principle of form cannot be ontologically exhausted by structure. That is, I deny form should be understood just as the arrangement of an object's parts. I do so by showing that structure cannot play the role form is supposed to in a certain domain of objects, specifically, in (...) mereological simples. Thus, I show that Hylomorphism does not reduce to Structuralism. I also draw out some important consequences from my argument for Hylomorphism in general. (shrink)

Mathematical pluralism notes that there are many different kinds of pure mathematical structures—notably those based on different logics—and that, qua pieces of pure mathematics, they are all equally good. Logical pluralism is the view that there are different logics, which are, in an appropriate sense, equally good. Some, such as Shapiro, have argued that mathematical pluralism entails logical pluralism. In this brief note I argue that this does not follow. There is a crucial distinction to be drawn between the preservation (...) of truth and the preservation of truth-in-a-structure; and once this distinction is drawn, this suffices to block the argument. The paper starts by clarifying the relevant notions of mathematical and logical pluralism. It then explains why the argument from the first to the second does not follow. A final section considers a few objections. (shrink)

How have human cultures engaged with and thought about animals, plants, rocks, clouds, and other elements in their natural surroundings? Do animals and other natural objects have a spirit or soul? What is their relationship to humans? In this new study, Graham Harvey explores current and past animistic beliefs and practices of Native Americans, Maori, Aboriginal Australians, and eco-pagans. He considers the varieties of animism found in these cultures as well as their shared desire to live respectfully within larger (...) natural communities. Drawing on his extensive casework, Harvey also considers the linguistic, performative, ecological, and activist implications of these different animisms. (shrink)

The paper argues that the view that the particular quantifier is ‘existentially loaded’ is a relatively new one historically and that it has become entrenched in modern philosophical logic for less than happy reasons.

Anti-reductionists hold that beliefs based upon comprehension (of both force and content) of tellings are non-inferentially justified. For reductionists, on the other hand, comprehension as such is not in itself a warrant for belief: beliefs based on it are justified only if inferentially supported by other beliefs. I discuss Elizabeth Fricker's argument that even if anti-reductionism is right in principle, its significance is undercut by the presence of background inferential support: for mature knowledgeable adults, justification from comprehension as such plays (...) no active role, and is superseded by inferential warrant. I show that her argument begs important questions. Inferential and non-inferential support combine to over-determine the justification of comprehension-based beliefs. (shrink)

_The Internet: A Philosophical Inquiry_ develops many of the themes Gordon Graham presented in his highly successful radio series, _The Silicon Society_. Exploring the tensions between the warnings of the Neo-Luddites and the bright optimism of the Technophiles, Graham offers the first concise and accessible exploration of the issues which arise as we enter further into the world of Cyberspace. This original and fascinating study takes us to the heart of questions that none of us can afford to (...) ignore: how does the Internet affect our concepts of identity, moral anarchy, censorship, community, democracy, virtual reality and imagination? Free of jargon and full of stimulating ideas, this is essential reading for anyone wishing to think clearly and informatively about the complexities of our technological future. (shrink)

Buddhism and Marxism may seem unlikely bedfellows, since they come from such different times and places, and appear to address such different concerns. But the two have at least this much in common: both say that life, as we find it, is unsatisfactory; both have a diagnosis of why this is; and both offer the hope of making it better. In this paper, I argue that aspects of each complement aspects of the other. In particular, Buddhism provides a stable ethical (...) base that Marxism always lacked; and Marxism provides a sophisticated political philosophy, which Buddhism never had. I will explain those aspects of each of the two on which I wish to draw, and then explain how they are complementary. (shrink)

I address two related questions. First: what value is there in visiting a museum and becoming acquainted with the objects on display? For art museums the answer seems obvious: we go to experience valuable works of art, and experiencing valuable works of art is itself valuable. In this paper I focus on non-art museums, and while these may house aesthetically valuable objects, that is not their primary purpose, and at least some of the objects they house might not be particularly (...) aesthetically valuable at all. Second: to what ontologicaltypeorcategorydo museum objects belong? Whattypeof item should be featured on an inventory of a museum collection? I distinguish betweentypicalobjects andspecialobjects. While these are different types of object, both, I argue, areabstracta, notconcreta. The answer to the second question, concerning the ontological category of special objects, throws new light on various philosophical questions about museums and their collections, including the question about the value of museum experiences. But it also throws light on important questions concerning the preservation and restoration of museum objects. (shrink)

This paper discusses the major theme of Adrian Moore’s The Evolution of Modern Metaphysics. Moore argues that the philosophical theories of many modern Western philosophers, seen as the project of making sense of the world—in the most general sense of that notion—lead to self-referential contradiction. I agree with him. Moore takes this as a sign that this project requires the need of some non-propositional notion of making sense. Contrary to this, I argue (as in Beyond the Limits of Thought) that (...) it simply indicates the dialetheias at the limits of the project. (shrink)

This paper concerns two paradoxes involving propositions. The first is Russell's paradox from Appendix B of The Principles of Mathematics, a version of which was later given by Myhill. The second is a paradox in the framework of possible worlds, given by Kaplan. This paper shows a number of things about these paradoxes. First, we will see that, though the Russell/myhill paradox and the Kaplan paradox might appear somewhat different, they are really just variants of the same phenomenon. Though they (...) do this in different ways, the core of each paradox is to use the notion of a proposition to construct a function, f, from the power set of some set into the set itself. Next we will see how this paradox fits into the Inclosure Schema. Finally, I will provide a model of the paradox in question, showing its results to be non‐trivial, though inconsistent. (shrink)

There is a phenomenon that often arises when a philosophy argues that there are limits to thought/language, and tries to justify this view by giving reasons as to why there are things about which one cannot think/talk---in the process appearing to give the lie to the claim. I will be concerned with that phenomenon. We will look at some of philosophies that fall into this camp (those of Wittgenstein, Heidegger, and Mahayana Buddhism). We will then see that Buddhist philosophy has (...) resources to address this kind of issue not present in Western traditions, namely the catuskoti and its developments. The catuskoti is a principle to the effect that claims can be true, false, both, or neither. Later developments add a fifth possibility: ineffability. Of course, one might be skeptical that such ideas can be made logically respectable. I will show how to do so with some simple tools from contemporary non-classical logic. (shrink)

In the context of an unprecedented level of human harm to the natural world on a global scale, this essay aims to rehabilitate the category of the natural by drawing on the philosophies of the classical Daoist Zhuangzi and Friedrich Nietzsche. It considers the benefits of their undermining of anthropocentrism, their appreciation of natural limitations, their checking of human projections onto nature, and their recommendations concerning following the ways of nature while at the same time promoting human culture. The essay (...) concludes with a few examples of how these ideas apply to some current environmental issues. (shrink)

In this Introduction, we begin with two relatively uncontroversial matters: the broad contours of the history of discussion of ontological arguments, and the major topics that require discussion in connection with ontological arguments. We then move on to consideration of the much more difficult task of the characterisation of ontological arguments—i.e. the task of saying exactly what ontological arguments are and explaining how they differ from, say, cosmological, teleological, and moral arguments for the existence of God—and then the equally contested (...) question of the provision of general objections to ontological arguments, including, in particular, attempts to show that there could not possibly be a successful ontological argument. Finally, we consider some often-neglected questions about how to assess the merits of arguments, with a particular eye on the assessment of the merits of ontological arguments. (shrink)
