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.

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.

This chapter provides a quick sketch of the history of western philosophy of religion as it bears on theism.

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.

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.

This paper provides a taxonomy of cosmological arguments and givesgeneral reasons for thinking that arguments that belong to a given category do not succeed.

This two volume works provides a comprehensive history of philosophy in Australia and New Zealand. Volume one provides a chronological history, with one chapter devoted to the early years in which idealism dominated Australasian philosophy, and then chapters that cover each of the decades from the second world war. Volume two provides a thematic history, with treatment of most of the major areas to which Australasian philosophers have made significant contributions.

This chapter is an invited contribution to a book on the naturalness of theistic belief. I start by considering ordinary usage of the term 'natural'. I then clarify how I shall use the terms 'naturalism', 'theism', 'worldview' and 'big picture'. I consider the demographic spread of commitment to theistic big pictures and naturalistic big pictures. I consider the distribution of happiness over those committed to theistic big pictures and naturalistic big pictures. I consider the distribution of reasons over those committed (...) to theistic big pictures and naturalistic big pictures. I consider whether intuitive considerations favour one kind of big picture over the other. As it often the case, I draw somewhat irenic conclusions from these considerations. (shrink)

Naturalists have many and diverse reasons for thinking that morality does not depend upon God. In this paper, I do not aim to give an exhaustive inventory of these reasons. Rather, I aim to give reason that emerge from the kind of naturalism that I accept. After explaining what I mean by "God", "morality" and "dependence", I note that, on the kind of naturalism that I accept, it is impossible that God exists. Unsurprisingly, therefore, I hold that it is impossible (...) that morality depends on God. While--as I go on to discuss--there are reasons to think that morality could not be dependent on anything else, I also canvass reasons for thinking that even theists should worry about the suggestion that morality might be dependent on God. -/- This chapter was published in a 'debate' book. My 'debate' partner was Matthew Flannagan. The book also contains my response to Flannagan's chapter on this topic. I have not included that response here. (shrink)

The fifth of the five volumes in our History of Western Philosophy of Religion. This volume deals with Western philosophy of religion in the twentieth century. It contains chapters on: James; Bergson; Whitehead; Hartshorne; Dewey; Russell; Scheler; Buber; Maritain; Jaspers; Tillich; Barth; Wittgenstein; Heidegger; Levinas; Weil; Ayer; Alston; Hick; Daly; Derrida; Plantinga; and Swinburne.

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.

In this paper, I offer a novel analysis of logical arguments from evil. I claim that logical arguments from evil have three parts: (1) characterisation (attribution of specified attributes to God); (2) datum (a claim about evil); and (3) link (connection between attributes and evil). I argue that, while familiar logical arguments from evil are known to be unsuccessful, it remains an open question whether there are successful logical arguments from evil.

This is the text of my OBO entry on arguments for the existence of God.

This chapter provides a brief account of atheistic philosophy of relgion in the second half of the twentieth century.

This paper is an English version of the paper that was published in German under the title: "Über die Aussichten erfolgreicher Beweise für Theismus oder Atheismus". My English paper was translated into German by Gabriele Schlegel. -/- The aim of this paper is to examine the prospects for proofs or successful arguments for the existence or non-existence of God.

This paper provides an overview of 'analytic' philosophy of religion. It begins with a historical sketch. It then examines some of the kinds of questions that are investigated by 'analytic' philosophers of religion. It concludes with brief discussion of possible futures for 'analytic' philosophy of religion. There is also a very short appendix on the treatment of Islam and Arabic philosophy within 'analytic' philosophy of religion.

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.

The History of Western Philosophy of Religion brings together an international team of over 100 leading scholars to provide authoritative exposition of how history's most important philosophical thinkers - from 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. Together these volumes provide an indispensable resource for anyone conducting research or teaching in the philosophy of religion and related fields, such as theology, religious studies, the history of philosophy, and the history of ideas. Volume 3 covers the early modern period which witnessed a revolution in science and natural philosophy that swept away two millennia of Aristotelian certainty in a human-centred universe. Covering some of the most important figures in the history of Western thought - notably Descartes, Locke, Hume and Kant - Early Modern Philosophy of Religion charts the philosophical understanding of religion at a time of intellectual and spiritual revolution.

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.

This is the fourth volume in our five volume history of western philosophy of religion. It covers the nineteenth century, and includes chapters on: Fichte; Schleiermacher; Hegel; Schelling; Schopenhauer; Comte; Newman; Emerson; Feuerbach; Mill; Darwin; Kierkegaard; Marx; Engels; Dilthey; Edward Caird; Nietzche; Royce; Freud; and Durkheim.

Sceptical theists--e.g., William Alston and Michael Bergmann--have claimed that considerations concerning human cognitive limitations are alone sufficient to undermine evidential arguments from evil. We argue that, if the considerations deployed by sceptical theists are sufficient to undermine evidential arguments from evil, then those considerations are also sufficient to undermine inferences that play a crucial role in ordinary moral reasoning. If cogent, our argument suffices to discredit sceptical theist responses to evidential arguments from evil.

In this paper, I review evidence which strongly supports the claim that life will eventually be extinguished from the universe. I then examine the ethical implications of this evidence, focusing, in particular, on the question whether it is a bad thing that life will eventually die out.

This paper is a discussion of an ontological argument defended by E. J. Lowe in the *Routledge Companion to Philosophy of Religion* (edited by C. Meister and P. Copan, at pp.332-40). The volume to which this paper belongs contains an article by Lowe which defends a different ontological argument from the one that I discuss.

This paper rejects the imposition of "semantic innocence" as a constraint on semantic theories. In particular, it argues that recent attempts to justify the imposition of "semantic innocence" as a constraint on semantic theories fail.

General discussion of ontological arguments. (Extended the discussion of ontological arguments in the then current version of my SEP entry on ontological arguments.).

This paper, while neutral on questions about the minimality of truth, argues for the non-minimality of truth-aptness.

Agnosticism has had some bad press in recent years. Nonetheless, I hope to show that agnosticism can be so formulated that it is no less philosophically respectable than theism and atheism. This is not a mere philosophical exercise; for, as it happens, the formulated position is--I think--the one to which I subscribe. I include a qualification here since it may be that the position to which I subscribe is better characterised as fallibilist atheism--but more of that anon.

This paper is my second contribution to the Szatkowski volume. In the first paper, I provide a critical discussion of Bob Maydole's ontological arguments. In this second paper, I respond to Maydole's critical response to my first paper. My overall verdict is that Maydole does not successfully defend his arguments against my critical attack.

This paper discusses the treatment of "infinity" in philosophy of religion, including its use in discussions of divine attributes, and its use in various arguments about the existence of God (including the kalam cosmological argument and Pascal's wager). The aim of the paper is to set out -- and where possible, to resolve -- various foundational problems about infinity.

This paper is a response to William Lane Craig's criticisms of my previous paper "Uncaused Beginnings". I argue that Craig's criticisms do not inflict any damage on the arguments of that earlier paper.

This chapter gives an exposition and critique of Anselm's Proslogion II argument.

A discussion of the recent prominence of 'new atheism' and 'Christian nationalism' in the United States.

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. (shrink)

A number of authors have developed evidential arguments from evil in the past thirty years. Perhaps the best known evidential arguments from evil are those presented in Rowe (1979) and Draper (1989). We shall spend most of this chapter examining these two arguments.

This paper provides a detailed examination of Michael Martin’s Atheism: A Philosophical Justification (1990). I argue that Martin’s project in this book is seriously damaged by his neglect of high-level theoretical considerations about rationality, justification, and argumentation. Furthermore, I suggest that this failing is endemic to recent discussions of arguments about the existence of God: there is no prospect of making progress in this area unless much more attention is paid to high-level theoretical questions about the connections between rationality, justification, (...) and argumentation.

I discuss J. P. Moreland's arguments from consciousness. I argue for the conclusion that considerations about consciousness favor naturalism over theism.

This paper compares the doxastic credentials of the claim that nothing comes from nothing with the doxastic credentials of the claim that there is no causing without changing. I argue that comparison of these two claims supports my contention that considerations about causation do nothing to make theism more attractive than naturalism.

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.

This paper is an assessment of Robert Maydole's work on ontological arguments. (Bibliographical details are provided in the text.) I argue that Maydole's ontological arguments are unsuccessful.

This paper was part of a special online issue on Truth. I critically discuss Peter Geach's paper "Truth and God".

This paper compares overall cases for the existence of God, an evil God, and a morally neutral God. It argues that, while atheists can reasonably believe that the overall case for the existence of God is no better than the case for the existence of an evil God, and is perhaps worse than the case for the existence of a morally neutral God, theists can reasonably believe that the case for the existence of God is better than the cases for (...) the existence of an evil God and the existence of a morally neutral God.

In this paper we respond to criticisms by Michael Bergmann and Michael Rea in their “In Defense of Sceptical Theism : A Reply to Almeida and Oppy,” Australasian Journal of Philosophy 83.

This paper provides a discussion of philosophy as it bears on spirituality and healthcase. Topics take up include: flourishing; health; disease; spirituality; adversity, virtue; and religion.

This paper critically examines Roger Teichmann's defence of the claim that it is impossible to refer to future individuals. (Bibliographical details are provided in the article.).

This article is a brief overview of major ontological arguments. The most noteworthy feature of this article is the statement of a new parody of the Anselmian and Cartesian arguments that is obviously immune to objections adverting to intrinsic minima and maxima.

This is a short introduction to ontological arguments. It begins with a brief characterization of ontological arguments that proceeds mainly by way of example. The rest of the discussion is given over to consideration of what looks like a very simple ontological argument. This consideration turns up many of the issues that arise when more complex ontological arguments are examined.

Nick Trakakis and Yujin Nagasawa criticise the argument in Almeida and Oppy . According to Trakakis and Nagasawa, we are mistaken in our claim that the sceptical theist response to evidential arguments from evil is unacceptable because it would undermine ordinary moral reasoning. In their view, there is no good reason to think that sceptical theism leads to an objectionable form of moral scepticism. We disagree. In this paper, we explain why we think that the argument of Nagasawa and (...) Trakakis fails to overthrow our objection to sceptical theism. (shrink)
