In "Evil and the Justice of God", N.T. Wright presses the point that attempting to solve the philosophical problem of evil is an immature response to the existence of evil--a response that belittles the real problem of evil, which is just the fact that evil is bad and needs to be dealt with. As you might expect, I am not inclined to endorse this sort of sweeping indictment of the entire field of research on the philosophical problem of evil. (I (...) sort of doubt that Wright really meant to either.) But I do think that there is a kernel of truth in what I take to be Wright's fundamental objection to attempts to solve the philosophical problem of evil. In the first section of what follows, I will try briefly to explain why. I will then go on to argue that, despite this fact, certain efforts at solving the problem of evil avoid Wright's objection. Indeed, drawing on recent work by Elenore Stump, I will argue that one perfectly legitimate way to try to solve the philosophical problem of evil is to follow precisely what seems to be the main piece of advice in "Evil and the Justice of God": namely, to look more seriously than we have at the attitudes taken toward evil by human authors of and characters in the Bible, and to attend more carefully to what the Bible says about how God deals with evil.

Since the 1960s, metaphysics has flourished in Anglo-American philosophy. Far from wanting to avoid metaphysics, philosophers have embraced it in droves. There have been critics, to be sure; but the criticisms have received answers and the enterprise has carried on.

The paper will have three sections. In section one I briefly present and respond to Byrne’s argument against theological realism. In section two, I present van Fraassen’s argument against analytic metaphysics and I show how, if sound, it constitutes a reason to reject both metaphysical and theological realism. In section three, I show how van Fraassen can be answered. Obviously what I am doing here falls far short of a full-blown defense of realism in either metaphysics or theology. But the (...) objections raised by van Fraassen and Byrne are tokens of a type of objection that I think is rather widely endorsed among those who are suspicious of these two brands of realism. Thus, responding to those objections constitutes an important first step in the direction of a defense. (shrink)

People attribute purposes in both mundane and profound ways—such as when thinking about the purpose of a knife and the purpose of a life. In three studies (total N = 13,720 observations from N = 3,430 participants), we tested whether these seemingly very different forms of purpose attributions might actually involve the same cognitive processes. We examined the impacts of four factors on purpose attributions in six domains (artifacts, social institutions, animals, body parts, sacred objects, and human lives). Study 1 (...) manipulated what items in each domain were originally created for (original design) and how people currently use them (present practice). Study 2 manipulated whether items are good at achieving a goal (effectiveness) and whether the goal itself is good (morality). We found effects of each factor in every domain. However, whereas morality and effectiveness had remarkably similar effects across domains, the effects of original design and present practice differed substantially. Finally, Study 3 revealed that, within domains, the effects of original design and present practice depend on which entities design and use items. These results reveal striking similarities in purpose attributions across domains and suggest that certain entities are treated as authorities over the purposes of particular items. (shrink)

In the first section, I characterize skeptical theism more fully. This is necessary in order to address some important misconceptions and mischaracterizations that appear in the essays by Maitzen, Wilks, and O’Connor. In the second section, I describe the most important objections they raise and group them into four “families” so as to facilitate an orderly series of responses. In the four sections that follow, I respond to the objections.

The standard argument to the conclusion that artificial intelligence (AI) constitutes an existential risk for the human species uses two premises: (1) AI may reach superintelligent levels, at which point we humans lose control (the ‘singularity claim’); (2) Any level of intelligence can go along with any goal (the ‘orthogonality thesis’). We find that the singularity claim requires a notion of ‘general intelligence’, while the orthogonality thesis requires a notion of ‘instrumental intelligence’. If this interpretation is correct, they cannot be (...) joined as premises and the argument for the existential risk of AI turns out invalid. If the interpretation is incorrect and both premises use the same notion of intelligence, then at least one of the premises is false and the orthogonality thesis remains itself orthogonal to the argument to existential risk from AI. In either case, the standard argument for existential risk from AI is not sound.—Having said that, there remains a risk of instrumental AI to cause very significant damage if designed or used badly, though this is not due to superintelligence or a singularity.

This essay develops a theory of identities, selves, and ‘the self’ that both explains the sense in which selves are narratively constituted and also explains how the self relates to a person's individual autobiographical identity and to their various social identities. I argue that identities are the contents of narratively structured representations, some of which are hosted individually and are autobiographical in form, and others of which are hosted collectively and are biographical in form. These identities, in turn, give rise (...) to selves of various sorts—true selves, autobiographical selves, public and private selves, merely possible selves, and so on—which are the characters (or presupposed subjects) that appear in our various identities. Although the theory I develop bears some obvious affinities with the view that selves are fictional characters, the two views are in fact distinct, for reasons explained at the end. (shrink)

My goal in this paper is to show that naturalists cannot reasonably endorse moral realism. My argument will come in two parts. The first part aims to show that any plausible and naturalistically acceptable argument in favor of belief in objective moral properties will appeal in part to simplicity considerations (broadly construed)—and this regardless of whether moral properties are reducible to non-moral properties. The second part argues for the conclusion that appeals to simplicity justify belief in moral properties only if (...) either those properties are not objective or something like theism is true. Thus, if my argument is sound, naturalists can reasonably accept moral realism only if they are prepared to accept something like theism. But, as will become clear, naturalists can reasonably accept theism or something like it only if belief in some such doctrine is justified by the methods of science. For present purposes, I’ll assume (what I think virtually every naturalist will grant) that belief in theism and relevantly similar doctrines is not justified by the methods of science. Thus, I will conclude that naturalists cannot reasonably accept moral realism. (shrink)

In the present article, he explains why divine silence poses a serious intellectual obstacle to belief in God, and then goes on to consider ways of overcoming that obstacle. After considering several ways in which divine silence might actually be beneficial to human beings, he argues that perhaps silence is nothing more or less than God’s preferred mode of interaction with creatures like us. Perhaps God simply desires communion rather than overt communication with human beings, and perhaps God has provided (...) ways for us to experience God’s presence richly even amidst the silence.

The “Value Alignment Problem” is the challenge of how to align the values of artificial intelligence with human values, whatever they may be, such that AI does not pose a risk to the existence of humans. Existing approaches appear to conceive of the problem as "how do we ensure that AI solves the problem in the right way", in order to avoid the possibility of AI turning humans into paperclips in order to “make more paperclips” or eradicating the human race (...) to “solve climate change”. This paper proposes an approach to Alignment rooted in the Enactive theory of mind that reconceptualises it as "how do we make relevant to AI what it relevant to humans". This conceptualisation is supported with a discussion of 4E cognition and goes on to suggest that the Alignment problem and the Frame problem are the same problem. The paper concludes with a discussion of the tradeoffs of the different approaches to value alignment. (shrink)

The question raised by this volume is “How successful is naturalism?” The question presupposes that we already know what naturalism is and what counts as success. But, as anyone familiar with the literature on naturalism knows, both suppositions are suspect. To answer the question, then, we must first say what we mean in this context by both ‘naturalism’ and ‘success’. I’ll start with ‘success’. I will then argue that, by the standard of measurement that I shall identify here, naturalism is (...) an utter failure. (shrink)

One of the main tasks for an account of the Christian doctrine of the atonement is to explain how and in what ways the salvifically relevant work of Christ heals the damage wrought by human sin on our souls, our relationships with one another, and our relationship with God. One kind of damage often neglected in philosophical treatments of the atonement, but discussed at some length in Eleonore Stump’s forthcoming At-one-ment, is what she, following St. Thomas Aquinas, calls the stain (...) on the soul. The stain on the soul comprises the “moral leftovers” of serious evil, damage to the soul that goes beyond the guilt, shame, and separation from God brought about by sin and that lingers in a person even after she has repented and been forgiven. In this paper, I critically examine Stump’s account of how the work of Christ deals with the problem of the stain on the soul. I offer reasons for thinking that if the stain is exactly as she describes it, then it is indelible; and then I explore possible ways forward for her account of the atonement. (shrink)

In World Without Design: The Ontological Consequences of Naturalism, I argued that there is an important sense in which naturalism’s current status as methodological orthodoxy is without rational foundation, and I argued that naturalists must give up two views that many of them are inclined to hold dear—realism about material objects and materialism. In a review recently published in Faith and Philosophy, Dale Jacquette alleges that my arguments in World Without Design are directed mainly against strawmen and that I have (...) neglected to discuss at least one formulation of naturalism that straightforwardly addresses my main objections. In this reply, I show that these and other objections raised by Jacquette are unsound and, in fact, rest on egregious misrepresentations of the book. (shrink)

The Christian doctrine of the Trinity poses a serious philosophical problem. On the one hand, it seems to imply that there is exactly one divine being; on the other hand, it seems to imply that there are three. There is another well-known philosophical problem that presents us with a similar sort of tension: the problem of material constitution. We argue in this paper that a relatively neglected solution to the problem of material constitution can be developed into a novel solution (...) to the problem of the Trinity. (shrink)

We lay out the fatalist’s argument, making sure to clarify which dialectical moves are available to the libertarian. We then offer a more robust presentation of Ockhamism, responding to obvious objections and teasing out the implications of the view. At this point, we discuss presentism and eternalism in more detail. We then present our argument for the claim that the libertarian cannot take Ockham’s way out of the fatalism argument unless she rejects presentism. Finally, we consider and dispense with objections (...) to our argument. In the end, it ought to be clear that the libertarian must make a choice between Ockham’s way out and presentism. (shrink)

Conferralism is the view that social properties are neither intrinsic to the things that have them nor possessed simply by virtue of their causal or spatiotemporal relations to other things, but are somehow bestowed (intentionally or not, explicitly or not) upon them by persons who have both the capacity and the standing to bestow them. We argue that conferralism faces a dilemma: either it is viciously circular, or it is limited in scope in a way that undercuts its motivation.

In May 2010, philosophers, family and friends gathered at the University of Notre Dame to celebrate the career and retirement of Alvin Plantinga, widely recognized as one of the world's leading figures in metaphysics, epistemology, and the philosophy of religion. Plantinga has earned particular respect within the community of Christian philosophers for the pivotal role that he played in the recent renewal and development of philosophy of religion and philosophical theology. Each of the essays in this volume engages with some (...) particular aspect of Plantinga's views on metaphysics, epistemology, or philosophy of religion. Contributors include Michael Bergman, Ernest Sosa, Trenton Merricks, Richard Otte, Peter VanInwagen, Thomas P. Flint, Eleonore Stump, Dean Zimmerman and Nicholas Wolterstorff. The volume also includes responses to each essay by Bas van Fraassen, Stephen Wykstra, David VanderLaan, Robin Collins, Raymond VanArragon, E. J. Coffman, Thomas Crisp, and Donald Smith. (shrink)

While philosophers hold that it is patently absurd to blame robots or hold them morally responsible [1], a series of recent empirical studies suggest that people do ascribe blame to AI systems and robots in certain contexts [2]. This is disconcerting: Blame might be shifted from the owners, users or designers of AI systems to the systems themselves, leading to the diminished accountability of the responsible human agents [3]. In this paper, we explore one of the potential underlying reasons for (...) robot blame, namely the folk's willingness to ascribe inculpating mental states or "mens rea" to robots. In a vignette-based experiment (N=513), we presented participants with a situation in which an agent knowingly runs the risk of bringing about substantial harm. We manipulated agent type (human v. group agent v. AI-driven robot) and outcome (neutral v. bad), and measured both moral judgment (wrongness of the action and blameworthiness of the agent) and mental states attributed to the agent (recklessness and the desire to inflict harm). We found that (i) judgments of wrongness and blame were relatively similar across agent types, possibly because (ii) attributions of mental states were, as suspected, similar across agent types. This raised the question - also explored in the experiment - whether people attribute knowledge and desire to robots in a merely metaphorical way (e.g., the robot "knew" rather than really knew). However, (iii), according to our data people were unwilling to downgrade to mens rea in a merely metaphorical sense when given the chance. Finally, (iv), we report a surprising and novel finding, which we call the inverse outcome effect on robot blame: People were less willing to blame artificial agents for bad outcomes than for neutral outcomes. This suggests that they are implicitly aware of the dangers of overattributing blame to robots when harm comes to pass, such as inappropriately letting the responsible human agent off the moral hook.

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.

Recent research shows – somewhat astonishingly – that people are willing to ascribe moral blame to AI-driven systems when they cause harm [1]–[4]. In this paper, we explore the moral- psychological underpinnings of these findings. Our hypothesis was that the reason why people ascribe moral blame to AI systems is that they consider them capable of entertaining inculpating mental states (what is called mens rea in the law). To explore this hypothesis, we created a scenario in which an AI system (...) runs a risk of poisoning people by using a novel type of fertilizer. Manipulating the computational (or quasi-cognitive) abilities of the AI system in a between-subjects design, we tested whether people’s willingness to ascribe knowledge of a substantial risk of harm (i.e., recklessness) and blame to the AI system. Furthermore, we investigated whether the ascription of recklessness and blame to the AI system would influence the perceived blameworthiness of the system’s user (or owner). In an experiment with 347 participants, we found (i) that people are willing to ascribe blame to AI systems in contexts of recklessness, (ii) that blame ascriptions depend strongly on the willingness to attribute recklessness and (iii) that the latter, in turn, depends on the perceived “cognitive” capacities of the system. Furthermore, our results suggest (iv) that the higher the computational sophistication of the AI system, the more blame is shifted from the human user to the AI system. (shrink)

Substantial review of Michael Rea's, World without design: the ontological consequences of naturalism. It is an improved version of my paper, "Rea On Naturalism" in Philo, 2004, revised in light of Rea's comments on the earlier paper. The discussion focuses on Rea’s case for three of his theses: that naturalism must be viewed as a ‘research programme’; that naturalism ‘cannot be adopted on the basis of evidence’, as he puts it; and that naturalists cannot be justified in accepting realism (...) about material objects.

T In [Rea 2006], Michael Rea presents an argument that presentism is incompatible with a libertarian view of human freedom and the unrestricted principle of bivalence. I aim to show that Rea’s argument fails. The outline of my paper is as follows. In Part I, I briefly explain the above three views and I present Rea’sargument. In Part II, I argue that one of the premises of the argument is unjustified.

My goal in this paper is to provide critical discussion of Michael Rea’s case for three of the controversial theses defended in his World Without Design (Oxford University Press, 2002): (1) that naturalism must be viewed as what he calls a “research program”; (2) that naturalism “cannot be adopted on the basis of evidence,” as he puts it; and (3) that naturalists cannot be justified in accepting realism about material objects.

In an important discussion of the problem of hiddenness, Michael Rea briefly presents and defends an argument from divine hiddenness which he thinks encapsulates the problem of divine hiddenness, and then develops a detailed and nuanced response to this argument. Importantly, Rea claims that his response does not depend on the commonly held theistic view that God allows hiddenness to secure human goods. In this paper I offer a detailed criticism of Rea’s account of what justifies God in allowing (...) divine hiddenness, arguing that Rea’s response to the argument from divine hiddenness is unsuccessful.

At a first approximation, we might answer that it is the psychological attitude picked out by standard uses of the English locution “S has faith that p,” where p takes declarative sentences as instances, as in “He has faith that they’ll win”. Although correct, this answer is not nearly as informative as we might like. Many people say that (...) there is a more informative answer. They say that, at the very least, propositional faith requires propositional belief. More precisely, they say that faith that p requires belief that p or that it must be partly constituted by belief that p. This view is common enough; call it the Common View. I have two main aims in this paper: (i) to exhibit the falsity of the Common View and the paucity of reasons for it, and (ii) to sketch a more accurate and comprehensive account of what propositional faith is.

Reprinted in Philosophical and Theological Essays on the Trinity, Oxford, 2009, eds Michael Rea and Thomas McCall. In this essay, I assess a certain version of ’social Trinitarianism’ put forward by J. P. Moreland and William Lane Craig, ’trinity monotheism’. I first show how their response to a familiar anti-Trinitarian argument arguably implies polytheism. I then show how they invoke three tenets central to their trinity monotheism in order to avoid that implication. After displaying these tenets more fully, I (...) argue that Trinitarians would do well to hold Moreland’s and Craig’s trinity monotheism at arms length. (shrink)

The open secret of analytic philosophy of religion since its 20th century revival has been that it is for the most part a revival of philosophical theology, and particularly Christian philosophical theology. More recently, Christian analytic philosophers and theologians sympathetic to them have transformed this open secret into a research program by explicitly thematizing the use of analytic philosophical tools for the particular work of Christian theology. Dubbing this work as “analytic theology” (AT) Oliver Crisp and Michael Rea have (...) succeeded in inaugurating AT as a distinct subregion in the philosophy of religion. Besides prompting a spate of first-rate philosophical work theorizing a variety of Christian theological commitments, the advent of AT has also prompted a good deal of meta-theological reflection: Is AT more conducive for certain conceptions of Christian theology than others? Among the various kinds of theology produced by AT, liberation theology is notably absent. In this paper, I offer a diagnosis of why that might be, outline an argument for analytic engagement with liberation theology, and sketch what such an engagement might consist in. (shrink)

Jesus claimed to be divine, but if his claim was false, then either he was insane (mad) or lying (bad), both of which are very unlikely; so, he was divine. I present two objections to this argument. The first, the dwindling probabilities objection, contends that even if we make generous probability (...) assignments to the relevant pieces of evidence for Jesus’ divinity, the probability calculus tell us to suspend judgement on the matter. The second, and more telling objection in my opinion, the merely mistaken objection, contends that it is no less plausible to suppose that Jesus was neither mad nor bad but merely mistaken than that he was divine.

In this article we survey Ásta’s (2008, 2013) conferralist account of essence, which provides a broadly anti-realist picture of essence. We first offer some thoughts on the difference between realist and anti-realist accounts of essence in general. Then we present Ásta’s notion of a conferred property and sketch her conferralist account of essence. Finally, we examine some critical questions conferralism faces.

On September 26th, 2023, the National Institute on Minority Health and Health Disparities (NIMHD) officially designated disabled people as a health disparity population, marking the most significant event for disabled people's health as it relates to the NIH.

I argue that, given evidence of the factors that tend to distort our intuitions, ethical intuitionists should disown a wide range of common moral intuitions, and that they should typically give preference to abstract, formal intuitions over more substantive ethical intuitions. In place of the common sense morality with which intuitionism has traditionally allied, the suggested approach may lead to a highly revisionary normative ethics.

The best accuracy arguments for probabilism apply only to credence functions with finite domains, that is, credence functions that assign credence to at most finitely many propositions. This is a significant limitation. It reveals that the support for the accuracy-first program in epistemology is a lot weaker than it seems at first glance, and it means that accuracy arguments cannot yet accomplish everything that their competitors, the pragmatic (Dutch book) arguments, can. In this paper, I investigate the extent to which (...) this limitation can be overcome. Building on the best arguments in finite domains, I present two accuracy arguments for probabilism that are perfectly general—they apply to credence functions with arbitrary domains. I then discuss how the arguments’ premises can be challenged. We will see that it is particularly difficult to characterize admissible accuracy measures in infinite domains. (shrink)

An interview with Ed Casey where we discuss the intersections of his philosophical work with current political issues, including the Israel-Palestine conflict.

Here I pose a challenge to realism about knowledge, the view that facts about knowledge are non-trivially mind-independent, adapting an evolutionary debunking argument from metaethics. In brief: Our beliefs about knowledge are the products of innate knowledge-representing capacities with a deep and well documented evolutionary history, and, crucially, this history indicates that such capacities are indifferent to whether there are any mind-independent facts about knowledge. Instead, knowledge-representing capacities are likely just a byproduct of processing limitations on primate cognition. This presents (...) an explanatory challenge for the knowledge realist—How is it, then, that we nonetheless happen to have many true beliefs about knowledge? I’ll argue that, without abandoning the non-naturalism that characterizes much of contemporary epistemology, realism struggles to provide a compelling answer. In contrast, evolutionary anti-realism, the view advocated for here, meets the explanatory challenge head-on. Facts about knowledge are grounded in facts about what our innate knowledge-representing capacities classify as knowledge, so it’s no surprise that we have many true beliefs about knowledge. While none of this shows that realism about knowledge is false, these considerations give us ceteris paribus reason to prefer an anti-realist approach. (shrink)

Epistemic decision theory produces arguments with both normative and mathematical premises. I begin by arguing that philosophers should care about whether the mathematical premises (1) are true, (2) are strong, and (3) admit simple proofs. I then discuss a theorem that Briggs and Pettigrew (2020) use as a premise in a novel accuracy-dominance argument for conditionalization. I argue that the theorem and its proof can be improved in a number of ways. First, I present a counterexample that shows that one (...) of the theorem’s claims is false. As a result of this, Briggs and Pettigrew’s argument for conditionalization is unsound. I go on to explore how a sound accuracy-dominance argument for conditionalization might be recovered. In the course of doing this, I prove two new theorems that correct and strengthen the result reported by Briggs and Pettigrew. I show how my results can be combined with various normative premises to produce sound arguments for conditionalization. I also show that my results can be used to support normative conclusions that are stronger than the one that Briggs and Pettigrew’s argument supports. Finally, I show that Briggs and Pettigrew’s proofs can be simplified considerably. (shrink)

Reciprocal Ethics is a novel ethical framework rooted in praxeology, the study of purposeful action. It represents an entirely new paradigm in moral philosophy, placing interaction at the core of universal ethics. Traditional ethical theories often divorce thought from action. Reciprocal Ethics contends that they are two aspects of the same phenomenon in the human experience, removing the traditional boundary between theoretical and practical ethics. The system categorizes all social interaction as either “self-directed” or “other-directed”, and by introducing the concept (...) of "normative signaling" it also exerts legitimate prescriptive power. The theory is a self-consistent, purely descriptive approach to ethics, that suggests that one's actions serve as semiotic signs that signal one's ethical stance in social interaction. Hence actions do not only define individual moral profiles, but also the moral ecosystem within which one actually operates. The theory operates in real time, adapting to the complexity of reality by taking into account uncertainty, incomplete data and social asymmetries. Reconciling elements of consequentialism and deontological theories, Reciprocal Ethics delivers a streamlined, yet comprehensive ethical system for social interaction, offering tangible insights for navigating complex moral dilemmas. By synthesizing descriptive metaethics and normative moral philosophy into one comprehensive formal theory, a bold assertion arises: Reciprocal Ethics becomes the Formal Science of Ethics. (shrink)

In recent years, philosophers have proposed a variety of accounts of the nature of harm. In this paper, I consider several of these accounts and argue that they are unsuccessful. I then make a modest case for a different view.

ABSTRACT:Organismal superposition holds that the same individual both is and is not an organism, as a consequence of organismal pluralism. When coupled with the assumption that death is the cessation of an organism, this entails that there is no unique answer as to whether brain death is biological death. This essay argues that concerns about organismal pluralism and superposition do not undermine a theory of biological death, nor entail any metaphysical indeterminacy about the biological vital status of a brain-dead individual.

John Bell proposed an ontology for the GRW modification of quantum mechanics in terms of flashes occurring at space- time points. This article spells out the motivation for this ontology, inquires into the status of the wave function in it, critically examines the claim of its being Lorentz invariant, and considers whether it is a parsimonious but nevertheless physically adequate ontology.

I argue that prioritarianism cannot be assessed in abstraction from an account of the measure of utility. Rather, the soundness of this view crucially depends on what counts as a greater, lesser, or equal increase in a person’s utility. In particular, prioritarianism cannot accommodate a normatively compelling measure of utility that is captured by the axioms of John von Neumann and Oskar Morgenstern’s expected utility theory. Nor can it accommodate a plausible and elegant generalization of this theory that has been (...) offered in response to challenges to von Neumann and Morgenstern. This is, I think, a theoretically interesting and unexpected source of difficulty for prioritarianism, which I explore in this article. (shrink)

Defends Kantian paternalism: Interference with an individual’s liberty for her own sake is justified absent her actual consent only to the extent that such interference stands a reasonable chance of preventing her from exercising her liberty irrationally in light of the rationally chosen ends that constitute her conception of the good.
