Al-Taftāzānī introduces the Liar Paradox, in a commentary on al-Rāzī, in a short passage that is part of a polemic against the ethical rationalism of the Muʿtazila. In this essay, we consider his remarks and their place in the history of the Liar Paradox in Arabic Logic. In the passage, al-Taftāzānī introduces Liar Cycles into the tradition, gives the paradox a puzzling name—the fallacy of the “irrational root” —which became standard, and suggests a connection between the paradox and what it (...) tells us about truth and falsehood, and arguments for divine voluntarism and what they tell us about the nature of goodness and badness. On this last point, we also discuss a passage from al-Rāzī, which suggests similar connections. (shrink)

Some people (e.g., Drs. Paul and Susan Lim) and, with them, organizations (e.g., the National Embryo Donation Center) believe that, morally speaking, the death of a frozen human embryo is a very bad thing. With such people and organizations in mind, the question to be addressed here is as follows: if one believes that the death of a frozen embryo is a very bad thing, ought, morally speaking, one prevent the death of at least one frozen embryo via embryo adoption? (...) By way of a three‐premise argument, one of which is a moral principle first introduced by Peter Singer, my answer to this question is: at least some of those who believe this ought to. (Just who the “some” are is identified in the paper.) If this is correct, then, for said people, preventing the death of a frozen embryo via embryo adoption is not a morally neutral matter; it is, instead, a morally laden one. Specifically, their intentional refusal to prevent the death of a frozen embryo via embryo adoption is, at a minimum, morally criticizable and, arguably, morally forbidden. Either way, it is, to one extent or another, a moral failing. (shrink)

We describe the earliest occurrences of the Liar Paradox in the Arabic tradition. e early Mutakallimūn claim the Liar Sentence is both true and false; they also associate the Liar with problems concerning plural subjects, which is somewhat puzzling. Abharī (1200-1265) ascribes an unsatisfiable truth condition to the Liar Sentence—as he puts it, its being true is the conjunction of its being true and false—and so concludes that the sentence is not true. Tūsī (1201-1274) argues that self-referential sentences, like the (...) Liar, are not truth-apt, and defends this claim by appealing to a correspondence theory of truth. Translations of the texts are provided as an appendix. (shrink)

According to the theory of intrinsic value and moral standing called the ‘substance view,’ what makes it prima facie seriously wrong to kill adult human beings, human infants, and even human fetuses is the possession of the essential property of the basic capacity for rational moral agency – a capacity for rational moral agency in root form and thereby not remotely exercisable. In this critique, I cover three distinct reductio charges directed at the substance view's conclusion that human fetuses have (...) the same intrinsic value and moral standing as adult human beings. After giving consideration to defenders of the substance view's replies to these charges, I then critique each of them, ultimately concluding that none is successful. Of course, in order to understand all of these things – the reductio charges, defenders of the substance view's replies to them, and my criticisms of their replies – one must have a better understanding of the substance view as well as its defense. Accordingly, I address the substance view's understanding of rational moral agency as well as present its defense. (shrink)

In an essay on performance-enhancing drugs, author Chuck Klosterman (2007) argues that the category of enhancers extends from hallucinogens used to inspire music to steroids used to strengthen athletes—and he criticizes those who would excuse one means of enhancement while railing against the other as a form of cheating: After the summer of 1964, the Beatles started taking serious drugs, and those drugs altered their musical performance. Though it may not have been their overt intent, the Beatles took performance-enhancing drugs. (...) And . . . absolutely no one holds it against them. No one views “Rubber Soul” and “Revolver” as “less authentic” albums, despite the fact that they would not (and probably could .. (shrink)

In my articles ‘The Substance View: A Critique’ and ‘The Substance View: A Critique,’ I raise objections to the substance view, a theory of intrinsic value and moral standing defended by a number of contemporary moral philosophers, including Robert P. George, Patrick Lee, Christopher Tollefsen, and Francis Beckwith. In part one of my critique of the substance view, I raise reductio-style objections to the substance view's conclusion that the standard human fetus has the same intrinsic value and moral standing as (...) the standard adult human being, among other human beings. In part two, I raise objections to some of the premises invoked in support of that conclusion. Here, in part three, I raise objections to Henrik Friberg-Fernros's attempt to rebut some of the aforementioned objections. (shrink)

In my initial critique of the substance view, I raised reductio-style objections to the substance view's conclusion that the standard human fetus has the same intrinsic value and moral standing as the standard adult human being, among others. In this follow-up critique, I raise objections to some of the premises invoked in support of this conclusion. I begin by briefly presenting the substance view as well as its defense. (For a more thorough presentation, see the first part of my critique.) (...) I then raise objections to three claims involved in the substance view's defense: the claim that the standard human fetus's intrinsic value and moral standing is a function of its potentiality; the claim that the standard human fetus's intrinsic value and moral standing is a function of its essential properties; and the claim that it is the possession of the basic potential for rational moral agency that best accounts for the wrongness of killing the standard human fetus, among others.

According to the principle that ‘ought’ implies ‘can’, it is never the case that you ought to do something you cannot do. While many accept this principle in some form, it also has its share of critics, and thus it seems desirable if an argument can be offered in its support. The aim of this paper is to examine a particular way in which the principle has been defended, namely, by appeal to considerations of fairness. In a nutshell, the idea (...) (due to David Copp) is that moral requirements we cannot comply with would be unfair, and there cannot be unfair moral requirements. I discuss several ways of spelling out the argument, and argue that all are unsatisfactory for a variety of reasons. (shrink)

Why does American law allow the recreational use of some drugs, such as alcohol, tobacco, and caffeine, but not others, such as marijuana, cocaine, and heroin? The answer lies not simply in the harm the use of these drugs might cause, but in the perceived morality—or lack thereof—of their recreational use. Despite strong rhetoric from moral critics of recreational drug use, however, it is surprisingly difficult to discern the reasons they have for deeming the recreational use of (some) drugs morally (...) wrong. In this book, Rob Lovering lays out and dissects various arguments for the immorality of using marijuana, cocaine, heroin, and other drugs recreationally. He contends that, by and large, these arguments do not succeed. Lovering's book represents one of the first works to systematically present, analyze, and critique arguments for the moral wrongness of recreational drug use. Given this, as well as the popularity of the morality-based defense of the United States' drug laws, this book is an important and timely contribution to the debate on the recreational use of drugs.

Many debates in the philosophy of religion, particularly arguments for and against the existence of God, depend on a claim or set of claims about what God—qua sovereign, omnipotent, omniscient, and perfectly good being— would do , either directly or indirectly, in particular cases or in general. Accordingly, before these debates can be resolved we must first settle the more fundamental issue of whether we can know, or at least have justified belief about, what God would do. In this paper, (...) I lay out the possible positions on the issue of whether we can know what God would do, positions I refer to as Broad Skeptical Theism, Broad Epistemic Theism, and Narrow Skeptical Theism. I then examine the implications of each of these views and argue that each presents serious problems for theism. (shrink)

David Lewis is typically interpreted as a class nominalist. One consequence of class nominalism, which he embraced, is that the reduction of ordered pairs, triples, etc to unordered sets of sets is conventional. The reaction by his Australian counterparts D.M. Armstrong and Peter Forrest was that Lewis was not being ontologically serious. This chapter evaluates this debate over serious ontology. It is argued that in one sense Lewis is ontologically serious, but that his additional commitment to structuralism about classes should (...) push him to adopt a trope-theoretic account of naturalness, which opens up another way to respond to the charge of not doing serious ontology. This conclusion is supported by certain remarks he makes in his correspondence, thus revealing how his thinking about properties appears to have evolved from property-egalitarianism to a sparse theory of tropes.

Is prostitution immoral? In this book, Rob Lovering argues that it is not. Offering a careful and thorough critique of the many―twenty, to be exact―arguments for prostitution's immorality, Lovering leaves no claim unchallenged. Drawing on the relevant literature along with his own creative thinking, Lovering offers a clear and reasoned moral defense of the world's oldest profession. Lovering demonstrates convincingly, on both consequentialist and nonconsequentialist grounds, that there is nothing immoral about prostitution between consenting adults. The legal implications of this (...) view are also brought to bear on the current discourse surrounding this controversial topic. (shrink)

God and Evidence presents a new set of compelling problems for theistic philosophers. The problems pertain to three types of theistic philosopher, which Lovering defines here as 'theistic inferentialists,' 'theistic non-inferentialists,' and 'theistic fideists.' Theistic inferentialists believe that God exists, that there is inferential probabilifying evidence of God's existence, and that this evidence is discoverable not simply in principle but in practice. Theistic non-inferentialists believe that God exists, that there is non-inferential probabilifying evidence of God's existence, and that this evidence (...) is discoverable not simply in principle but in practice. Theistic fideists believe that God exists, that there is no discoverable probabilifying evidence (inferential or non-inferential) of God's existence, and that it is nevertheless acceptable-morally if not otherwise-to have faith that God exists. Lovering argues that each type of theistic philosopher faces a problem unique to his type and that they all share two particular problems. Some of these problems take us down an entirely new discursive path; others down a new discursive path branching off from an old one. (shrink)

The phenomenon of “dirty hands” is often held to be endemic to political life. Success in politics—it has been argued—requires a willingness to sacrifice our moral principles in order to pursue worthwhile goals. I argue that the tension between morality and politics goes deeper than this. The very existence of “politics” requires that morality is routinely violated because political community, within which political discourse is possible, is based on denying the moral claims of non-members. Political community requires borders and borders (...) require keeping outsiders out. Yet there is no justification that we can provide to someone outside of our political community as to why they are denied membership. The price of political community is therefore the unjust exclusion of others. In a world characterised by the movement of peoples as a result of large-scale and systematic international injustices, this exclusion often involves acts that violate important obligations of compassion and respect. Thus, “we” are the barbarians my title refers to. In order for political community to exist, we must act like barbarians at the gates. A problem of “dirty hands” therefore lies at the very foundation of political community. (shrink)

Many people are strongly opposed to the intentional destruction of human embryos, whether it be for purposes scientific, reproductive, or other. And it is not uncommon for such people to argue against the destruction of human embryos by invoking the claim that the destruction of human embryos is morally on par with killing the following humans: (A) the standard infant, (B) the suicidal teenager, (C) the temporarily comatose individual, and (D) the standard adult. I argue here that this claim is (...) false and do so as follows. First, I provide an account of the prima facie wrongness of killing individuals (A) – (D). Briefly, I contend that individuals (A) – (D) have a certain property in common, that of having a future of value. An individual who has a future of value has the potential to (i) value goods of consciousness when he will (or would) experience them and (ii) do so as a psychologically continuous individual. And depriving an individual of a future of value is prima facie wrong. Killing an individual deprives him of a future of value. Thus, killing an individual who has a future of value is prima facie wrong. Since individuals (A) – (D) have futures of value, killing them is prima facie wrong. Second, I argue that, given this account of the prima facie wrongness of killing individuals (A) – (D), the destruction of individual (E), the standard embryo, is not morally on par with killing individuals (A) – (D). For, unlike individuals (A) – (D), the standard embryo does not have a future of value. Specifically, I argue that having a future of value involves having the second-order potential for psychological continuity, a potential that individuals (A) – (D) have but that individual (E) does not. For possessing the second-order potential for psychological continuity requires the possession of psychological states, something individuals (A) – (D) have but that individual (E) lacks. Hence, individual (E) does not share with individuals (A) – (D) the property of having a future of value and, in turn, is not deprived of one when it is killed. Thus, given my proposed account of the prima facie wrongness of killing individuals (A) – (D), killing individual (E) is not morally on par with killing individuals (A) – (D). (shrink)

W. K. Clifford famously argued that it is “wrong always, everywhere and for anyone, to believe anything upon insufficient evidence.” Though the spirit of this claim resonates with me, the letter does not. To wit, I am inclined to think that it is not morally wrong for, say, an elderly woman on her death bed to believe privately that she is going to heaven even if she does so on insufficient evidence—indeed, and lest there be any confusion, even if the (...) woman herself deems the evidence for her so believing to be insufficient. After all, her believing so does not appear to endanger, harm, or violate the rights of anyone, nor does it make the world a worse place in a significant, if any, way. That Clifford might have put too fine a point on the matter, however, does not entail that there are no conditions under which it is wrong to believe something upon insufficient evidence. In this paper, I argue that, in cases where believing a proposition (read: believing a proposition to be true) will affect others, it is prima facie wrong to have propositional faith—for present purposes, to believe the proposition despite deeming the evidence for one’s believing to be insufficient—before one has attempted to believe the proposition by proportioning one’s belief to the evidence.

When it comes to explaining someone’s puzzling, objectionable, or otherwise problematic behavior, one type of explanation occasionally employed in the service of doing so is as follows: “That’s just so-and-so being so-and-so.” But what, exactly, do explanations of the type “That’s just so-and-so being so-and-so” mean? More specifically, in what way, if any, is it meaningful or informative to say such things? And what is the precise function of such explanations of someone’s behavior? Is it merely to present what one (...) takes to be the underlying causes of the behavior, or something beyond that? In what follows, I lay out a few possibilities—basic possibilities, to be precise, given philosophy’s keen interest in fundamentals—with respect to the various meanings, functions, and moral implications of explanations of the type “That’s just so-and-so being so-and-so.” While doing so, I apply these basic possibilities to three tokens of this kind of explanation: “That’s just Manny being Manny” (in reference to Manny Ramirez, the former professional baseball player), “That’s just Charlie being Charlie” (in reference to Charlie Rose, the former television host), and “That’s just Trump being Trump” (in reference to Donald Trump, the current President of the United States).

Is prostitution immoral? Various philosophers have put forward arguments for thinking so, one of the most notable being that, by engaging in sexual activity with someone for payment, the prostitute instrumentalizes himself or herself. In this paper, I identify two meanings of "instrumentalize" and, with them, two versions of the instrumentalization argument for the immorality of prostitution. I then critique each version of the argument.

According to the theory of intrinsic value and moral standing known as the “substance view,” all human beings have intrinsic value, full moral standing and, with these, a right to life. The substance view has been defended by numerous contemporary philosophers who use the theory to argue that the standard human fetus has a right to life and, ultimately, that abortion is prima facie seriously wrong. In this paper, I identify three important errors committed by some of these philosophers in (...) their defense of the theory---what I refer to as the “extratheoretical-proposition error,” “quantitative-differences error,” and “non-normative-answer error”---and conclude that these errors render their defense inadequate.

That theistic evidentialist philosophers have failed to make the evidential case for theism to atheistic evidentialist philosophers raises a problem—a question to be answered. I argue here that—of the most plausible possible solutions to this problem—each is either inadequate or, when adequate, in conflict with the theistic evidentialist philosophers’ defining beliefs. I conclude that the problem of the theistic evidentialist philosophers—the question of why theistic evidentialist philosophers have failed to make their case to atheistic evidentialist philosophers—is a problem for theistic (...) evidentialist philosophers—an objection to their defining beliefs.

The topic of divine omniscience is well-trodden ground, with philosophers and theologians having asked virtually every question there is to ask about it. The questions regarding God's omniscience to be addressed here are as follows. First, is omniscience best understood as maximal propositional knowledge along with maximal experiential knowledge? I argue that it is. Second, is it possible for God to be essentially omniscient? I argue that it is not.

Many theists who identify themselves with the Abrahamic religions maintain that it is perfectly acceptable to have faith that God exists. In this paper, I argue that, when believing that God exists will affect others, it is prima facie wrong to forgo attempting to believe that God exists on the basis of sufficient evidence. Lest there be any confusion : I do not argue that it is always wrong to have faith that God exists, only that, under certain conditions, it (...) can be. (shrink)

Stephen Maitzen has recently argued that ordinary morality implies atheism. In the following, I argue that the soundness of Maitzen’s argument depends on a principle that is implausible, what I call the Recipient’s Benefit Principle: All else being equal, if an act A produces a net benefit for the individual on the receiving end of A, then one cannot have a moral obligation to prevent A. Specifically, the Recipient’s Benefit Principle (RBP) must be true if premise (2) of Maitzen’s argument (...) is to be true. But, RBP is likely false, as it generates counterintuitive implications as well as conflicts with another principle both plausible and seemingly adopted by most of us, what I call the Preventing Immorality Principle: All else being equal, if an act A is seriously immoral, then one has a moral obligation to prevent A.

There is a wide array of arguments for the immorality of recreational drug use, ranging from the philosophically rudimentary to the philosophically sophisticated. But the vast majority of these arguments are unsuccessful, and those that succeed are quite limited in scope. In this article, I present and evaluate a few examples of such arguments.

Elizabeth Harman has recently proposed a new theory of moral status, the Ever Conscious View. It is the view that "a being has moral status at a time just in case it is alive at that time and there is a time in its life at which it is conscious" (Harman, 2007, 220). In other words, all and only beings that (1) are alive and (2) either were, are, or will be conscious have moral status. In the following, I examine (...) Harman's defense of her Ever Conscious View, raise a number of objections to it, and conclude that the Ever Conscious View is, as it stands, implausible. (shrink)

In this paper, I present a case study on a recent attempt at implementing what I refer to as the “Pro-lifer’s Asymmetrical Punishment View” (PAPV), the view that people should be legally punished for performing abortions whereas women should not be so punished for procuring abortions. While doing so, I argue that the endeavor, which took place in the state of Alabama, is incoherent relative to the conjunction of its purported underlying moral rationale and the Alabama criminal code. I then (...) present what I take to be possible explanations for, practical implications of, and solutions to the attempt and its incoherence. Given that other endeavors to implement PAPV are currently in the works and are so with similar underlying moral rationales and within similar criminal codes, what I present and argue here is not limited to Alabama’s attempt at doing so.

The Ontology for Biomedical Investigations (OBI) is an ontology that provides terms with precisely defined meanings to describe all aspects of how investigations in the biological and medical domains are conducted. OBI re-uses ontologies that provide a representation of biomedical knowledge from the Open Biological and Biomedical Ontologies (OBO) project and adds the ability to describe how this knowledge was derived. We here describe the state of OBI and several applications that are using it, such as adding semantic expressivity to (...) existing databases, building data entry forms, and enabling interoperability between knowledge resources. OBI covers all phases of the investigation process, such as planning, execution and reporting. It represents information and material entities that participate in these processes, as well as roles and functions. Prior to OBI, it was not possible to use a single internally consistent resource that could be applied to multiple types of experiments for these applications. OBI has made this possible by creating terms for entities involved in biological and medical investigations and by importing parts of other biomedical ontologies such as GO, Chemical Entities of Biological Interest (ChEBI) and Phenotype Attribute and Trait Ontology (PATO) without altering their meaning. OBI is being used in a wide range of projects covering genomics, multi-omics, immunology, and catalogs of services. OBI has also spawned other ontologies (Information Artifact Ontology) and methods for importing parts of ontologies (Minimum information to reference an external ontology term (MIREOT)). The OBI project is an open cross-disciplinary collaborative effort, encompassing multiple research communities from around the globe. To date, OBI has created 2366 classes and 40 relations along with textual and formal definitions. The OBI Consortium maintains a web resource providing details on the people, policies, and issues being addressed in association with OBI. (shrink)

I demonstrate that Deleuze's identification of Aion as an empty form offers a fascinating model of temporality that prioritises variation. First, I suggest that Deleuze's identification of time as an empty form is supported by ancient Greek and Gnostic concepts of the relation of Aion and Chronos. From Plato, through Aristotle, to Plotinus the concept of time undergoes substantive revision, in the sense that temporal measurement becomes removed from the measurement of existent entities. This gradual untethering of time from movement (...) gives rise to the development of the concept of eternity as an ontologically comprehensive mode of time that is devoid of content. It is here, with Deleuze's reading of the Platonic cosmology, that we see the first hints of the suggestion that Aion is involved with ontogenesis. Eternity is characterised as: a temporal ‘all’ that is non-reducible to the determinacy implied by any particular temporally localised existent or temporal series ; that which tends towards a diversity of possible states of affairs. Perhaps one of the most interesting aspects in the long history of Aion is that – in the ancient world – it was used in magical incantations. For the Gnostics and Oracles, Aion was a deity, and a potent one at that. From the Gnostic papyri, we get a vision of Aion as a force which enjoys eternal realisation. I suggest that the papyri conjure an image of Aion as a deity that is liberated from time, in the sense that it enjoys a neutrality with respect to the movements of any particular entity or group of entities – a form, in the most general sense of the term. Then, to clarify this mercurial aspect of an empty form of time, I elaborate on a complex analogy between Aion and Deleuze's concept of an ‘ideal game’ – an analogy that Deleuze specifies through reference to Fitzgerald and Borges. The claim is that Aion is an analogue of an ideal game in the sense that both share essential properties. Both Aion and the ideal game involve the multiplication of chance. Finally, I suggest that the differential aspects of Aion imply that it is pure variability; something which can be illustrated through a differential equation. These yield the suggestion that Aion enjoys realisation as an ontogenetic force. I further claim that ontogenetic forces may enjoy expression as the content of literature and mathematics. In concrete terms, temporality is involved in the creation of existent entities, which may be illustrated as various types of continuous multiplicity. (shrink)

This essay presents a novel physicalist perspective on the fluidity of identity for concrete and abstract objects. The comprehensive definition of identity that is adopted considers an object's physical properties, location, and relationships to other things or events. The argument is developed through three premises: that the law of identity does not hold for concrete objects, that abstract objects depend on physical substrates and are thus in flux, and that even objects fixed in space and time may not have a (...) fixed identity. The conclusion is that the law of identity does not universally hold for tangible things, so-called abstract things; and finally, objects in a unique spatiotemporal location. The essay contributes to the ongoing philosophical discourse on identity and encourages readers to question traditional understandings of the law of identity. The implications of this argument extend beyond philosophy to fields such as biology, chemistry, and computer science, where a sound understanding of identity is critical. (shrink)

Trope theory is a leading metaphysical theory in analytic ontology. One of its classic statements is found in the work of Donald C. Williams who argued that tropes qua abstract particulars are the very alphabet of being. The concept of an abstract particular has been repeatedly attacked in the literature. Opponents and proponents of trope theory alike have levelled their criticisms at the abstractness of tropes and the associated act of abstraction. In this paper I defend the concept of a (...) trope qua abstract particular by rejecting arguments that purport to show that tropes should not be understood as abstract and by arguing that the abstractness of tropes plays an indispensable role in one of our more promising trope-theoretic analyses of universals and of concrete objects.

Philosophy in community projects provide powerful, immersive introductions to philosophical thinking for both children and tertiary students. Such introductions can jumpstart transformative learning as well as diversify who seeks out philosophy in the longer term, both in schools and in universities. Using survey responses from teachers, parents, participants, staff, and volunteers of two such programs – Eurekamp Oz! and philosothons – we show how participants find value in engaging in communities of inquiry and philosophical thinking more broadly. We argue correspondingly (...) that such philosophy in community projects are an asset to universities, both as highly successful university outreach programs and in offering high school, undergraduate, and postgraduate students mentoring and employment opportunities utilising their growing philosophical skills. For these reasons, philosophy in community programs provide alternative and supplementary pathways into sustained philosophical thinking to those available within traditional philosophy in the classroom approaches.

The concept of instantiation is realized differently across a variety of metaphysical theories. A certain realization of the concept in a given theory depends on what roles are specified and associated with the concept and its corresponding term as well as what entities are suited to fill those roles. In this paper, the classic realization of the concept of instantiation in a one-category ontology of abstract particulars or tropes is articulated in a novel way and defended against unaddressed objections.

David Enoch recently defended the idea that there are valid inferences of the form ‘it would be good if p, therefore, p’. I argue that Enoch's proposal allows us to infer the absurd conclusion that ours is the best of all possible worlds.

Aesthics: Art and moral attuning. Art can help us understand everyday moral deliberation. Better perhaps than ethics. People don’t just act randomly in moral situations nor do they argue internally about which ethical principle to follow before deciding what to do. We built our moral sensitivity whilst living our lives, adhering to aesthetic norms of interaction. Regular engagement with works of art educates our moral sensitivity.

In the ontology of music the Aristotelian theory of musical works is the view that musical works are immanent universals. The Aristotelian theory (hereafter Musical Aristotelianism) is an attractive and serviceable hypothesis. However, it is overlooked as a genuine competitor to the more well-known theories of Musical Platonism and nominalism. Worse still, there is no detailed account in the literature of the nature of the universals that the Aristotelian identifies musical works with. In this paper, I argue that the best (...) version of Musical Aristotelianism identifies musical works with structural universals. I first motivate the view by outlining its explanatory benefits. I then argue that Musical Aristotelianism is preferable to Musical Platonism and present a novel account of musical works as structural universals by developing D. M. Armstrong’s theory of structural universals. I discuss the consequences of Musical Aristotelianism with respect to on-going issues in debates about musical works and defend the view against an influential objection, concluding that Musical Aristotelianism is a genuine competitor in debates about the nature of musical works.

We present experimental evidence that people's modes of social interaction influence their construal of truth. Participants who engaged in cooperative interactions were less inclined to agree that there was an objective truth about that topic than were those who engaged in a competitive interaction. Follow-up experiments ruled out alternative explanations and indicated that the changes in objectivity are explained by argumentative mindsets: When people are in cooperative arguments, they see the truth as more subjective. These findings can help inform research (...) on moral objectivism and, more broadly, on the distinctive cognitive consequences of different types of social interaction. (shrink)

Truthmaker monism is the view that the one and only truthmaker is the world. Despite its unpopularity, this view has recently received an admirable defence by Schaffer :307–324, 2010b). Its main defect, I argue, is that it omits partial truthmakers. If we omit partial truthmakers, we lose the intimate connection between a truth and its truthmaker. I further argue that the notion of a minimal truthmaker should be the key notion that plays the role of constraining ontology and that truthmaker (...) monism is not necessary for an appropriate solution to the problem of finding truthmakers for negative truths. I conclude that we should reject truthmaker monism once and for all. (shrink)

Structural universals are a kind of complex universal. They have been put to work in a variety of philosophical theories but are plagued with problems concerning their compositional nature. In this article, we will discuss the following questions. What are structural universals? Why believe in them? Can we give a consistent account of their compositional nature? What are the costs of doing so?

In the early twentieth century, many philosophers in America thought that time should be taken seriously in one way or another. George P. Adams (1882-1961) argued that the past, present and future are all real but only the present is actual. I call this theory ‘actualist eternalism’. In this paper, I articulate his novel brand of eternalism as one piece of his metaphysical system and I explain how he argued for the view in light of the best explanations of temporal (...) experience and the present. I argue that his exploitation of analogies between time and modality offer some lessons for current debates about time such as the importance of providing a temporal epistemology. I also extract what I call the temporal boundary problem and argue that it gives rise to an unaddressed challenge for presentists and growing block theorists. (shrink)

This is a review of David Boonin's A Defense of Abortion (Cambridge University Press, 2002).

The notion of agency has been explored within research in moral psychology and, quite separately, within research in linguistics. Moral psychologists have suggested that agency attributions play a role in moral judgments, while linguists have argued that agency attributions play a role in syntactic intuitions. -/- To explore the connection between these two lines of research, we report the results of an experiment in which we manipulate syntactic cues for agency and show a corresponding impact on moral judgments. This result (...) suggests that the two effects observed previously — in morality and in syntax — might each be a reflection of a more general capacity to understand event structure. (shrink)

In this paper I examine Grace A. de Laguna’s theory of universals in its historical context and in relation to contemporary debates in analytic metaphysics. I explain the central features of her theory, arguing that her theory should be classified as a form of immanent realism and as a powers ontology. I then show in what ways her theory affords a theory of modality in terms of potentialities and discuss some of its consequences along the way.

The revival of analytic metaphysics in the latter half of the twentieth century is typically understood as a consequence of the critiques of logical positivism, Quine’s naturalization of ontology, Kripke’s Naming and Necessity, clarifications of modal notions in logic, and the theoretical exploitation of possible worlds. However, this explanation overlooks the work of metaphysicians at the height of positivism and linguisticism that affected metaphysics of the late twentieth century. Donald C. Williams is one such philosopher. In this paper I explain (...) how Williams’s fundamental ontology and philosophy of time influenced in part the early formation of David Lewis’s metaphysics. Thus, Williams played an important role in the revival of analytic metaphysics. (shrink)

Priority Theory is an increasingly popular view in metaphysics. By seeing metaphysical questions as primarily concerned with what explains what, instead of merely what exists, it promises not only an interesting approach to traditional metaphysical issues but also the resolution of some outstanding disputes. In a recent paper, Louis deRosset argues that Priority Theory isn’t up to the task: Priority Theory is committed to there being explanations that violate a formal constraint on any adequate explanation. This paper critically examines deRosset’s (...) challenge to Priority Theory. We argue that deRosset’s challenge ultimately fails: his proposed constraint on explanation is neither well-motivated nor a general constraint. Nonetheless, lurking behind his criticism is a deep problem for prominent ways of developing Priority Theory, a problem which we develop. (shrink)

It is controversial whether virtual reality should be considered fictional or real. Virtual fictionalists claim that objects and events within virtual reality are merely fictional: they are imagined and do not exist. Virtual realists argue that virtual objects and events really exist. This metaphysical debate might appear important for some of the practical questions that arise regarding how to morally evaluate and legally regulate virtual reality. For instance, one advantage claimed of virtual realism is that only by taking virtual objects (...) and events to be real can we explain our strong emotional reactions to certain virtual actions, as well as their potential immorality. This paper argues that emotional reactions towards, and wrongs within, virtual reality are consistent with its being merely fictional. The emotional and ethical judgments we wish to make regarding virtual reality do not provide any grounds for preferring virtual realism. (shrink)

David Lewis objected to theories that posit necessary connections between distinct entities and to theories that involve a magical grasping of their primitives. In On the Plurality of Worlds, Lewis objected to nondescript ersatzism on these grounds. The literature contains several reconstructions of Lewis’ critique of nondescript ersatzism but none of these interpretations adequately address his main argument because they fail to see that Lewis’ critique is based on broader methodological considerations. I argue that a closer look at his methodology (...) reveals the broader objection he presented against nondescript ersatzism. This objection, I further argue, remains a challenge for the ersatzer who posits structure-less entities as possible worlds. (shrink)

We criticize the bare theory of quantum mechanics -- a theory on which the Schrödinger equation is universally valid, and standard way of thinking about superpositions is correct.
