This paper is a reply to Robert Maydole’s “The Modal Perfection Argument for the Existence of a Supreme Being,” published in Philo 6, 2, 2003. I argue that Maydole’s Modal Perfection Argument fails, and that there is no evident way in which it can be repaired.

Some people -- including the present author -- have proposed and defended alternative restricted causal principles that block Robert Koons’s ’new’ cosmological argument without undermining the intuition that causation is very close to ubiquitous. In "Epistemological Foundations for the Cosmological Argument", Koons argues that any restricted causal principles that are insufficient for the purposes of his cosmological argument cause epistemological collapse into general scepticism. In this paper I argue, against Koons, that there is no reason to suppose that my (...) favourite restricted causal principle precipitates epistemological collapse into general scepticism. If we impose the ’same kinds’ of restrictions on causal epistemological principles and on principles of general causation, then we cannot be vulnerable to the kind of argument that Koons develops.

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)

Robert Koons has recently defended what he claims is a successful argument for the existence of a necessary first cause, and which he develops by taking “a new look” at traditional arguments from contingency. I argue that Koons’ argument is less than successful; in particular, I claim that his attempt to “shift the burden of proof” to non-theists amounts to nothing more than an ill-disguised begging of one of the central questions upon which theists and non-theists disagree. I also (...) argue that his interesting attempt to bridge (part of) the familiar gap between the claim that there is a necessary first cause and the claim that God exists is beset with numerous difficulties. (shrink)

Robert Koons claims that my previous critique of his “new” cosmological argument is vitiated by confusion about the nature of defeasible argumentation.In response, I claim that Koons misrepresents—and perhaps misunderstands—the nature of my objections to his “new” cosmological argument. The main claims which I defend are: (1) that the move from a non-defeasible to a defeasible causal principle makes absolutely no difference to the success of the cosmological argument in which it is contained; and (2) that, since it is (...) perfectly well understood that non-theists have many reasons for rejecting the defeasible causal principle, it is pointless to claim that the move to a defeasible principle brings about a shift in the “burden of proof”. (Since some people may have forgotten—or may choose to ignore—the fact that non-theists do have reasons for rejecting the defeasible causal principle, I also provide a discussion of a modest sample of these reasons.).

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

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 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)

In On the Nature and Existence of God, Richard Gale follows majority opinion in giving very short shrift to the doctrine of divine simplicity: in his view, there is no coherent expressible doctrine of divine simplicity. Rising to the implicit challenge, I argue that---contrary to what is widely believed---there is a coherently expressible doctrine of divine simplicity, though it is rather different from the views that are typically expressed by defenders of this doctrine. At the very least, I think that (...) I manage to show that there are ways of understanding the doctrine of divine simplicity that have not yet been adequately examined. (shrink)

In ‘Professor Mackie and the Kalam Cosmological Argument’ , 367–75), Professor William Lane Craig undertakes to demonstrate that J. L. Mackie's analysis of the kalam cosmological argument in The Miracle of Theism is ‘superficial’, and that Mackie ‘has failed to provide any compelling or even intuitively appealing objection against the argument’ . I disagree with Craig's judgement; for it seems to me that the considerations which Mackie advances do serve to refute the kalam cosmological argument. Consequently, the purpose of this (...) paper is to reply to Craig's criticisms on Mackie's behalf. (shrink)

This paper begins with a fairly careful and detailed discussion of the conditions under which someone who presents an argument ought to be prepared to concede that the argument is unsuccessful. The conclusions reached in this discussion are then applied to William Lane Craig’s defense of what he calls “the kalam cosmological argument.” Perhaps unsurprisingly, the chief contention of the paper is that Craig ought to be prepared to concede that “the kalam cosmological argument” is not a successful argument. The (...) paper pays particular attention to Craig’s recent criticisms of Adolf Grünbaum’s contention that “the kalam cosmological argument” presupposes “the normalcy of nothingness”; and it also addresses some methodological issues raised by Craig’s response to my previous criticisms of his replies to critiques of “the kalam cosmological argument” provided by Grünbaum, Hawking, and Davies.

I defend the view that it is possible for reality to have a contingent initial state under the causal relation even though it is impossible for any other (non-overlapping) parts of reality to have no cause. I claim that, while there are good theoretical and commonsense grounds for maintaining that it is simply not possible for non-initial parts of reality to have no cause, these good grounds do not require one to claim that it is impossible that reality has an (...) uncaused initial state.

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

In Pascal's Wager: A Study Of Practical Reasoning In Philosophical Theology ,[1] Nicholas Rescher aims to show that, contrary to received philosophical opinion, Pascal's Wager argument is "the vehicle of a fruitful and valuable insight--one which not only represents a milestone in the development of an historically important tradition of thought but can still be seen as making an instructive contribution to philosophical theology".[2] In particular, Rescher argues that one only needs to adopt a correct perspective in order to see (...) that Pascal's Wager argument is a good argument. Moreover, there seems to be a certain amount of contemporary support for Rescher's claim that Pascal's Wager argument can be seen to be a good argument when properly construed .[3] However, despite this recent trend to adopt a more sympathetic stance towards Pascal's Wager argument, I propose to defend the traditional view that Pascal's Wager argument is almost entirely worthless--at least from the theological standpoint. (No doubt, it has historical significance from the standpoint of decision theory; but that's a separate matter.). (shrink)

The main aim of this paper is to examine an almost universal assumption concerning the structure of Paley’s argument for design. Almost all commentators suppose that Paley’s argument is an inductive argument---either an argument by analogy or an argument by inference to the best explanation. I contend, on the contrary, that Paley’s argument is actually a straightforwardly deductive argument. Moreover, I argue that, when Paley’s argument is properly understood, it can readily be seen that it is no good. Finally---although I (...) do not stress this very much---I note that the points that I make about Paley’s argument can carryover to modern design arguments that are based upon the argument that Paley actually gives.

Anselmian theists claim (a) that there is a being than which none greater can be conceived; and (b) that it is knowable on purely—solely, entirely—a priori grounds that there is a being than which none greater can be conceived. In this paper, I argue that Anselmian Theism gains traction by conflating different interpretations of the key description ‘being than which no greater can be conceived’. In particular, I insist that it is very important to distinguish between ideal excellence and maximal (...) possible excellence. At the end of my paper, I illustrate the importance of this distinction by applying my discussion to the recent defence of Anselmian Theism in Nagasawa (Philos Q 58:577–591, 2008). (shrink)

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

Richard Gale and Alexander Pruss contend that their ‘new cosmological argument’ is an improvement over familiar cosmological arguments because it relies upon a weaker version of the Principle of Sufficient Reason than that used in those more familiar arguments. However, I note that their ‘weaker’ version of the Principle of Sufficient Reason entails the ‘stronger’ version of that principle which is used in more familiar arguments, so that the alleged advantage of their proof turns out to be illusory. Moreover, I (...) contend that, even if their argument did rely on a weaker version of the Principle of Sufficient reason, nontheists would still be perfectly within their rights to refuse to accept the conclusion of the argument. (shrink)

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.). (shrink)

This paper is a companion to an article that I published in *Oxford Studies in Philosophy of Religion*. The OSPR discusses the third chapter of Tim O'Connor's *Theism and Ultimate Explanation. This paper discusses a range of other issues that are not picked up in the OSPR discussion.

There seems to be a widespread conviction — evidenced, for example, in the work of Mackie, Dawkins and Sober — that it is Darwinian rather than Humean considerations which deal the fatal logical blow to arguments for intelligent design. I argue that this conviction cannot be well-founded. If there are current logically decisive objections to design arguments, they must be Humean — for Darwinian considerations count not at all against design arguments based upon apparent cosmological fine-tuning. I argue, further, that (...) there are good Humean reasons for atheists and agnostics to resist the suggestion that apparent design — apparent biological design and/or apparent cosmological fine-tuning — establishes (or even strongly supports) the hypothesis of intelligent design.

This paper discusses the teaching of -- and opposition to the teaching of -- evolutionary theory in Australian schools in the early twenty-first century.

A fairly lengthy book review that appears at the Secular Web.

This paper provides a semantics for propositional attitude ascriptions. (In this respect, the title of the paper is quite well chosen.).

Recently, many philosophers have supposed that the divine attribute of omnipotence is properly understood as some kind of maximal power. I argue that all of the best known attempts to analyse omnipotence in terms of maximal power are multiply flawed. Moreover, I argue that there are compelling reasons for supposing that, on orthodox theistic conceptions, maximal power is not one of the divine attributes.

This paper is an extended critical discussion of Jerrold Levinson's historical definition of art. I try out various different avenues of attack; it is not clear whether any of them is ultimately successful.

In this paper, I argue that -- contrary to widely received opinion -- logical arguments from evil are well and truly alive and kicking.

This paper is an examination of the contingent a priori and the necessary a posteriori. In particular, it considers -- and assesses -- the criticisms that Nathan Salmon makes of the views of Saul Kripke.

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.

Craig (1981) presents and defends several different kalam cosmological arguments. The core of each of these arguments is the following ur argument.

This paper is a response to a paper by Rich Davis in which he argues that David Lewis' modal realism is inconsistent with classical theism. I provide what I take to be a coherent modal realist formulation of classical theism.

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)

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

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)

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.

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.

First, I suggest that it is possible to make some further improvements upon the Gödelian ontological arguments that Pruss develops. Then, I argue that it is possible to parody Pruss's Gödelian ontological arguments in a way that shows that they make no contribution towards 'lowering the probability of atheism and raising the probability of theism'. I conclude with some remarks about ways in which the arguments of this paper can be extended to apply to the whole family of Gödelian ontological (...) arguments. (shrink)

In "To Bet The Impossible Bet", Harmon Holcomb III argues: (i) that Pascal's wager is structurally incoherent; (ii) that if it were not thus incoherent, then it would be successful; and (iii) that my earlier critique of Pascal's wager in "On Rescher On Pascal's Wager" is vitiated by its reliance on "logicist" presuppositions. I deny all three claims. If Pascal's wager is "incoherent", this is only because of its invocation of infinite utilities. However, even if infinite utilities are admissible, the (...) wager is defeated by the "many gods" and "many wagers" objections. Moreover, these objections do not rely on mistaken "logicist" presuppositions: atheists and agnostics traditionally and typically hold that they have no more--or at any rate, hardly any more--reason to believe in the traditional Christian God than they have to believe in countless alternative deities.

This paper examines Richard Swinburne's definitions of 'mental property' and 'physical property'. After some preliminary tidying up (Section 1), the paper introduces eight putative counter-examples to Swinburne's definitions (Section 2). The paper then considers amendments to Swinburne's account of 'mental property' (Section 3) and 'physical property' (Section 4) which deal with these counter-examples. Finally, the paper closes with some brief remarks about the metaphysics of properties (Appendix). Along the way, the paper provides various reasons for thinking that Swinburne's definitions are (...) hardly likely to be acceptable to non-theists. (shrink)

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 is a careful examination of the various approaches that Alvin Plantinga has taken towards natural theology over the course of his academic career (from *God and Other Minds* to *Warranted Christian Belief*). In his earliest works, Plantinga has a very clear and strict conception of the project of natural theology, and he argues very clearly (and correctly) that that project fails. In his middle works, Plantinga has a tolerably clear and slightly less strict conception of the project of (...) natural theology, and he argues—in my view unsuccessfully—that this project succeeds. In his later works, Plantinga has a much less clear and less strict conception of the project of natural theology, and it is much harder to determine whether there is any merit in the claims that he makes for natural theology as thus conceived.

Millican (Mind 113(451):437–476, 2004) claims to have detected ‘the one fatal flaw in Anselm’s ontological argument.’ I argue that there is more than one important flaw in the position defended in Millican (Mind 113(451):437–476, 2004). First, Millican’s reconstruction of Anselm’s argument does serious violence to the original text. Second, Millican’s generalised objection fails to diagnose any flaw in a vast range of ontological arguments. Third, there are independent reasons for thinking that Millican’s generalised objection is unpersuasive.

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.

As a matter of historical fact, most philosophers and theologians who have defended traditional theistic views have been moral realists. Some "divine command" theorists have held that the good is constituted by the content of divine approval -i.e. that things are good because, and insofar as, they have divine approval. However, even amongst those theists who hold that the good is independently constituted -i.e. those who hold that God's pattern of approval is explained by the fact that he approves of (...) all and only that which is good -the dominant meta ethic has been strongly realistic.

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.

In [3], Quentin Smith claims that `the Hartle-Hawking cosmology' is inconsistent with classical theism in a way which redounds to the discredit of classical theism; and, moreover, that the truth of `the Hartle- Hawking cosmology' would undermine reasonsed belief in any other varieties of theism which hold that the universe is created.

This paper is a reply to Jonah Schupbach's critique of a previous paper of mine on Paley's argument for design. (Bibliographical details for earlier publications are available in the paper.).

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.

I offer a minimal characterization of naturalism, with ontological, epistemological, psychological and evaluative dimensions. I explain why naturalism is attractive. I note that naturalists disagree among themselves about, among other things, the nature of values, beliefs, and abstractions. I close by responding to some standard objections to naturalism.

Consider truth predicates. Minimalist analyses of truth predicates may involve commitment to some of the following claims: (i) truth “predicates” are not genuine predicates -- either because the truth “predicate” disappears under paraphrase or translation into deep structure, or because the truth “predicate” is shown to have a non-predicative function by performative or expressivist analysis, or because truth “predicates” must be traded in for predicates of the form “true-in-L”; (ii) truth predicates express ineligible, non-natural, gerrymandered properties; (iii) truth predicates express (...) metaphysically lightweight properties; (iv) truth predicates have thin conceptual roles; (v) truth predicates express properties with no hidden essence; (vi) truth predicates express properties which have no causal or explanatory role in canonical formulations of fundamental theories.
