Interreligious Philosophical Dialogues provides a unique approach to the philosophy of religion, embracing a range of religious faiths and spiritualities. Each of these three volumes brings together five leading scholars and philosophers of religion, who engage in friendly but rigorous cross-cultural philosophical dialogue. Each participant in the dialogue, as a member of a particular faith tradition, is invited to explore and explain their core religious commitments, and how these commitments figure in their lived experience and in their relations to other religions and communities. This set of volumes uncovers the rich and diverse cognitive and experiential dimensions of religious belief and practice, pushing the field of philosophy of religion in bold new directions.

This paper discusses a wide range of anti-naturalistic argument from reason due to Balfour, Haldane, Joad, Lewis, Taylor, Moreland, Plantinga, Reppert, and Hasker. I argue that none of these arguments poses a serious challenge to naturalists who are identity theorists. Further, I argue that some of these arguments do not even pose prima facie plausible challenges to naturalism. In the concluding part of my discussion, I draw attention to some distinctive differences between Hasker’s anti-naturalistic arguments and the other anti-naturalistic arguments mentioned above.

This book guides readers through an investigation of religion from a naturalistic perspective and explores the very meaning of the term ‘religious naturalism’. Oppy considers several widely disputed claims: that there cannot be naturalistic religion; that there is nothing in science that poses any problems for naturalism; that there is nothing in religion that poses any serious challenges to naturalism; and that there is a very strong case for thinking that naturalism defeats religion. Naturalism and Religion: A Contemporary Philosophical Investigation is an ideal introduction for undergraduate and postgraduate students of religious studies and philosophy who want to gain an understanding of the key themes and claims of naturalism from a religious and philosophical perspective.

Atheism: The Basics is a concise and engaging introduction to belief in the non-existence of deities. Atheism has long fascinated people but debate around this controversial position may seem daunting. In this lively and lucid book, Graham Oppy addresses the following important questions: •　What does it mean to be an atheist? •　What is the difference between atheism, agnosticism, theism and innocence? •　How has atheism been distributed over time and place? •　What does science tell us about atheism? •　Are there good reasons to be an atheist? •　Are there good reasons not to be an atheist? •　What do we mean by ‘new atheism'? With a glossary of key terms and suggestions for further reading throughout, the book considers key philosophical arguments around atheism, making this an ideal starting point for anyone seeking a full introduction to the arguments between those who hold atheistic beliefs and those who do not.

An international team of over 100 leading scholars has been brought together to provide authoritative exposition of how history's most important philosophical thinkers - fron antiquity to the present day - have sought to analyse the concepts and tenets central to Western religious belief, especially Christianity. Divided, chronologically, into five volumes, _The History of Western Philosophy of Religion_ is designed to be accessible to a wide range of readers, from the scholar looking for original insight and the latest research findings to the student wishing for a masterly encapsulation of a particular philosopher's views. It will become the standard reference in the field. Features: each volume opens with a general introduction, presenting an overview of philosophy of religion in the period each essay opens with a brief biography, then outlines and analyses that philosopher's contribution to thinking on religion, and concludes with key further reading essays are cross-referenced, highlighting the development of major ideas and influences across history each volume closes with a chronology, presenting a contextual guide to the main religious, political, cultural and artistic events of the period each volume contains its own bibliography and index.

This dissertation presents a semantic theory for sentences of the form "S believes that A is F"--where "S" is a singular term which denotes a person, "A" is a non-empty proper name, and "F" is an unstructured predicate--according to which these sentences express relations between the person which "S" denotes and a quadruple which consists of: the entity denoted by "A"; a mode of presentation of the entity denoted by "A" to the person denoted by "S"; the property which is denoted by "F"; and a mode of presentation of the property denoted by "F" to the person denoted by "S". ;The major innovation in the theory is that the modes of presentation mentioned in and are claimed to be associated with the name "A" and the predicate "F" in a context-dependent way. This feature enables the theory to avoid Saul Kripke's well-known objections to theories in which modes of presentation are taken to be context-independent entities. Furthermore, the inclusion of the mode of presentation of the property denoted by "F" allows the theory to provide a solution to Stephen Schiffer's recent objections to "propositional" analysis of belief ascriptions. ;The dissertation contains extensions of this basic analysis to cover a wide range of more complex kinds of sentences ;Finally, this extended theory is applied to a wide range of well-known philosophical puzzles--e.g. the analysis of attitudes de se, the analysis of the contingent a priori, Kripke's puzzle about belief, linguistic arguments for eliminative materialism, etc.--and is shown to provide various insightful analyses.

Hypotheses about the shape of causal reality admit of both theistic and non-theistic interpretations. I argue that, on the simplest hypotheses about the causal shape of reality—infinite regress, contingent initial boundary, necessary initial boundary—there is good reason to suppose that non-theism is always either preferable to, or at least the equal of, theism, at least insofar as we restrict our attention merely to the domain of explanation of existence. Moreover, I suggest that it is perfectly proper for naturalists to be undecided between these simple hypotheses about the causal shape of reality: contrary to the proponents of cosmological arguments, there are no decisive objections to any of these simple hypotheses. (I argue this case in detail in connection with objections offered by William Lane Craig; however, I believe that the case holds quite generally.)

The Medieval period was one of the richest eras for the philosophical study of religion. Covering the period from the 6th to the 16th century, reaching into the Renaissance, "The History of Western Philosophy of Religion 2" shows how Christian, Islamic and Jewish thinkers explicated and defended their religious faith in light of the philosophical traditions they inherited from the ancient Greeks and Romans. The enterprise of 'faith seeking understanding', as it was dubbed by the medievals themselves, emerges as a vibrant encounter between - and a complex synthesis of - the Platonic, Aristotelian and Hellenistic traditions of antiquity on the one hand, and the scholastic and monastic religious schools of the medieval West, on the other. "Medieval Philosophy of Religion" will be of interest to scholars and students of Philosophy, Medieval Studies, the History of Ideas, and Religion, while remaining accessible to any interested in the rich cultural heritage of medieval religious thought.

The origins of the Western philosophical tradition lie in the ancient Greco-Roman world. This volume provides a unique insight into the life and writings of a diverse group of philosophers in antiquity and presents the latest thinking on their views on God, the gods, religious belief and practice. Beginning with the 'pre-Socratics', the volume then explores the influential contributions made to the Western philosophy of religion by the three towering figures of Socrates, Plato and Aristotle. The chapters that follow cover the the leading philosophers of the major schools of the ancient world - Epicureanism, Stoicism, Neoplatonism and the early Christian Church. "Ancient Philosophy of Religion" will be of interest to scholars and students of Philosophy, Classics and Religion, while remaining accessible to any interested in the rich cultural heritage of ancient religious thought.

There are various background issues that need to be discussed whenever the topic of conversation turns to religion and atheism. In particular, there are questions about how these terms are to be used in the course of the conversation. While it is sometimes the case that all parties to a conversation about religion and atheism have agreed what they mean by ‘religion’ and ‘atheism’, it is often enough the case that such conversations go poorly because the parties mean different things by ‘religion’ and ‘atheism’. In this paper, I discuss a range of questions about the meanings of ‘religion’ and ‘atheism’ that should be taken into account when we are asking global questions about ‘religion’ and ‘atheism’.

In Proslogion II, Anselm writes: "But surely when this same Fool hears what I am speaking about, namely ‘something-than-which-nothing-greater-can-be-thought’, he understands what he hears, and what he understands is in his mind, even if he does not understand that it actually exists. … Even the Fool, then, is forced to agree that something-than-which-nothing-greater-can-be-thought exists in the mind, since he understands this when he hears it, and whatever is understood is in the mind." In this paper, I provide a careful analysis of this argument. In my view, this is where the important action in Proslogion II is located.

This chapter consists of a series of reflections on widely endorsed claims about Christian philosophy and, in particular, Christian philosophy of religion. It begins with consideration of some claims about how (Christian) philosophy of religion currently is, and then moves on to consideration of some claims about how (Christian) philosophy of religion ought to be. In particular, the chapter offers critical scrutiny of the oft-repeated claim that we are currently in a golden age for Christian philosophy of religion.

This paper outlines an argument for atheism from naturalism that I have developed in more detail elsewhere (in particular, in *The Best Argument against God*). The overall shape of the argument is as follows: first, naturalism is simpler than theism; second, there is no data that naturalism does not explain at least as well as theism; and, third, naturalism entails atheism; so we have good reason to prefer atheism to theism. Note that this statement of the shape of the argument is NOT a statement of the argument itself.

Bartha (2012) conjectures that, if we meet all of the other objections to Pascal’s wager, then the many-Gods objection is already met. Moreover, he shows that, if all other objections to Pascal’s wager are already met, then, in a choice between a Jealous God, an Indifferent God, a Very Nice God, a Very Perverse God, the full range of Nice Gods, the full range of Perverse Gods, and no God, you should wager on the Jealous God. I argue that his requirement of [strongly] stable equilibrium is not well-motivated. There are other types of Gods, no less worthy of consideration than those that figure in Bartha’s deliberations, which are intuitively no worse wagers than the Jealous God. In particular, I have suggested that one does no worse to wager on a jealous cartel than one does to wager on a Jealous God. Moreover, I argue that there are other types of Gods, no less worthy of consideration than those that figure in Bartha’s deliberations, that make trouble for Pascal’s wager, but not because one would do better to wager on them rather than on a Jealous God. Finally, I argue that, if we suppose that infinitesimal credences are in no worse standing the infinite utilities, then we cannot accept the assumption—built into the relative utilities framework—that there cannot be infinitesimal credences.

It is a very curious thing that proponents of Idealism have considered it to be a satisfactory counter to ‘scepticism’, ‘nihilism’, and the like. On the contrary, it seems to me that Idealism is a very close cousin to ‘brain-in-a-vat’ scepticism and other anti-naturalistic fantasies. Moreover, it seems to me that Idealism is inferior to Naturalism for much the same kinds of reasons that ‘brain-in-a-vat’ scepticism and other anti-naturalistic fantasies are inferior to Naturalism: a proper weighing of theoretical virtues discloses that Naturalism is the most virtuous worldview.

In order to give a proper estimation of the place of the New Atheism in history, we shall need to have before us an overview of that history. So I shall begin with an appropriate sketch. Then I will try to give an account of the current global state of play, and to indicate some reasons why it seems reasonable to think that the worldview of the New Atheists is currently gaining ground, at least in certain quarters. After examining—and rejecting—some recent claims that the worldview of the New Atheists is actually now in decline, I will then conclude with some cautionary remarks about the difficulties of making longer term predictions about anything involving human affairs.

Max Charlesworth’s Philosophy and Religion: From Plato to Postmodernism is an erudite and scholarly work, grounded in an impressive command of the history of philosophy of religion. However, despite its many virtues, the work has some serious shortcomings, due more to what it overlooks than to what it includes. In this paper, I review Charlesworth’s taxonomy of approaches to philosophy of religion, and argue for an alternative taxonomy that does more justice to the diversity of religions and the evidence produced by social scientific studies of religion. In particular, I suggest that Charlesworth pays insufficient attention to the project of articulating, comparing and assessing competing religious and non-religious worldviews.

In this paper, I defend the suggestion that to be God is just to be the one and only god, where to be a god is to be a supernatural being or force that has and exercises power over the natural world but that is not, in turn, under the power of any higher ranking or more powerful category of beings or forces. I then go on to defend the following further claims: (1) there can be no more than one God; (2) ‘God’ is not a title-term; and (3) the use of the name ‘God’ by non-believers is not parasitic on the use of this name by believers.
