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 an enthusiastic review of a book edited by Butterfield and Pagonis.

This paper is a critique of Stephen Makin's ontological argument. To some extent, the argument of this paper is recapitulated in *Ontological Arguments and Belief in God* (CUP, 1996).

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

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 paper is a reply to a prior work by C. J. F. Williams in which he criticised David Kaplan's account of the contingent analytic. In this paper, I take myself to be defending Kaplan's views against Williams' attack.

This paper is a reply to Stephen Makin's response to my previous criticism of his defense of a conceptual ontological argument. (All relevant bibliographical details are provided in this paper.).

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.

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.

In “On Oppy’s Objections to the Modal Perfection Argument,” Philo 8, 2, 2005, 123–30, Robert Maydole argues that his modal perfection argument—set out in his “The Modal Perfection Argument for a Supreme Being,” Philo 6, 2, 2003, 299–313—“remains arguably sound” in the face of the criticisms that I made of this argument in my “Maydole’s 2QS5 Argument,” Philo 7, 2, 2004, 203–11. I reply that Maydole is wrong: his argument is fatally flawed, and his attempts to avoid the criticisms that (...) I have made of his argument are to no avail. (shrink)

Review of Graham Oppy *Ontological Arguments and Belief in God* (CUP).

In ‘The Kalam Cosmological Argument Neither Bloodied nor Bowed’ , David Oderberg provides four main criticisms of the line of argument which I developed in ‘Time, Successive Addition, and Kalam Cosmological Arguments’ . I argue here that none of these lines of criticism succeeds. Further I re-emphasise the point that those who maintain that the temporal series of past events is formed by ‘successive addition’ are indeed thereby committed to a highly contentious strict finitist metaphysics.

Each author first presents his own side, and then they interact through two rounds of objections and replies. Pedagogical features include standard form arguments, section summaries, bolded key terms and principles, a glossary, and annotated reading lists.

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)

This paper is a response to Bruce Langtry's criticisms of views advanced in my book *Ontological Arguments and Belief in God*. In particular, the paper discusses his criticisms of "the general objection" to ontological arguments that is developed in that work.

Review of Graham Oppy *Ontological Arguments and Belief in God* (CUP).

This paper is a response to an earlier paper by Mark Nelson in which he argues for the claim that the best judges of the merits of arguments for the existence of God are theists whose belief in God is properly basic. I criticise Nelson's argument, and pursue some questions about the significance of the conclusion for which he argues.

"Philosophy in Australia and New Zealand has been experiencing, for some time now, something of a 'golden age'. This is not to overlook, however, the rich philosophical past of Australasia, which - although heavily indebted to overseas trends - has managed to produce much distinctive and highly original work. These developments in the recent and distant past only serve to highlight the importance of documenting Australasia's great contribution to philosophy ... The Companion contains a wide range of encyclopaedia-like entries written (...) by leading philosophers, including biographical essays on selected philosophers, topics (existentialism, postmodernism etc) and controversies (e.g. the Orr case and the Sydney push), as well as shorter entries on associations, research centres, departments, journals, pedagogy, and international links. Important philosophical contributions made by those working outside of the academy are also included, as are the many inroads that have recently been made with the introduction of philosophy into the wider community (for example, in primary and secondary schools, and in various community-based forums such as the 'Socratic Dialogues' and 'Philosophy Cafes'). Despite, therefore, the concentration on institutionalised forms of philosophy in Australasia, due (if not overdue) recognition is also given to other aspects of Australasian philosophy."--publisher website.

This paper is a response to Tim Williamson's "The Contingent A Priori: Has It Anything To Do With Indexicals?" In that paper, Williamson claims to have produced an instance of a deeply contingent a priori truth that in no way turns on indexicals. In this paper, I suggest that Williamson has failed to substantiate this claim. In particular, I claim that one cannot know a priori that there is at least one believer without relying on some kind of indexicality.

Response to Maydole's criticism of my initial contribution to this volume.

This paper discusses the finite version of the two envelope paradox. (That is, we treat the paradox against the background assumption that there is only a finite amount of money in the world.).

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 is a Cambridge *Element*, on the topic of atheism and agnosticism. It contains four main parts. First, there is an introduction in which atheism and agnosticism are explained. Second, a theoretical background to assessment. Third, a case for preferring atheism to theism. Fourth, a case for preferring agnosticism to theism.

This paper is a response to David Oderberg's discussion of the Tristram Shandy paradox. I defend the claim that the Tristram Shandy paradox does not support the claim that it is impossible that the past is infinite.

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.

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.

This paper criticises the cosmological argument that Tim O'Connor provides in his book *Theism and Ultimate Explanation*.

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 article discusses some problems associated with religious disagreement and expertise.

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.

This collection contains chapters under eight headings: (1) Individual Thinkers; (2) Philosophical Movements; (3) Critiques of Theism; (4) Metaphysics; (5) Epistemology; (6) Ethics; (7) Politics; and (8) Critiques of Atheism.

This book is a collection of exchanges between Christian philosophers who adopt very different perspectives on Christianity.

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.

This paper defends the claim that the concept of God is the concept of the one and only god. The paper distinguishes between concepts and conceptions: among those who suppose that there is one and only one god, there are many different views about the properties that are possessed by that one god.

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.

This book is a discussion of a wide range of topics that bear on the existence of God. For each topic, there is a chapter by one (or more) theists, and a chapter by one (or more) atheists.

Critical review of Daniel Dombrowski's "Rethinking the Ontological Argument".

We criticise Shepard's notions of “invariance” and “universality,” and the incorporation of Shepard's work on inference into the general framework of his paper. We then criticise Tenenbaum and Griffiths' account of Shepard (1987b), including the attributed likelihood function, and the assumption of “weak sampling.” Finally, we endorse Barlow's suggestion that minimum message length (MML) theory has useful things to say about the Bayesian inference problems discussed by Shepard and Tenenbaum and Griffiths. [Barlow; Shepard; Tenenbaum & Griffiths].

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.

Feser (2017) presents and defends five proofs of the existence of God. Each proof is in two stages: the first stage proves the existence of something which, in the second stage, is shown to possess an appropriate range of divine attributes. Each proof is given two presentations, one informal and one formal. In this paper, I critically examine two premises from one of Feser's five first stage proofs. I provide reasons for thinking that naturalists reject both of these premises. In (...) my view, this enough to show that the proof fails: it fails to advance considerations that decide between theism and important competing positions. (shrink)

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.

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. (shrink)

This book begins with a careful taxonomy of divine attributes. It continues with detailed examinations of: divine infinity; divine simplicity; divine perfection; divine necessity; omnipotence; omniscience; divine goodness; divine beauty; divine fundamentality; divine will; divine freedom; etc.

Bu [makalede], nihai olarak kesin bir sonucu olduğunu iddia etmemekle birlikte, ateizm için geliştirebileceğim en iyi argümanı öne sürmeye çalışacağım ve ortaya koyacağım şeyin, Tanrı’nın varlığına dair yürütülen tartışmaların herhangi bir kısmındaki, en iyi argüman olduğunu iddia edeceğim.

Latest version of my SEP entry on ontological arguments, which first appeared in 1996. General discussion of ontological arguments. Includes a brief historical overview, a taxonomy of different kinds of ontological arguments, a brief survey of objections to the different kinds of ontological arguments identified in the taxonomy, and more extended discussions of Anselm's ontological argument (Proslogion 2), Godel's ontological argument, and Plantinga's ontological argument.

There has been a recent explosion of interest in the epistemology of disagreement. Much of the recent literature is concerned with a particular range of puzzle cases (discussed in the Cases section of my paper). Almost all of the papers that contribute to that recent literature make mention of questions about religious disagreement in ways that suggest that there are interesting connections between those puzzle cases and real life cases of religious disagreement. One important aim of my paper is to (...) cast doubt on that suggestion. More generally, the aim of my paper is to give a reasonably full account of the recent literature on the epistemology of disagreement, and then to give a serious discussion of some of the epistemological issues that are raised by real world religious disagreements.
