Advances in neuroscience implicate reentrant signaling as the predominant form of communication between brain areas. This principle was used in a series of masking experiments that defy explanation by feed-forward theories. The masking occurs when a brief display of target plus mask is continued with the mask alone. Two masking processes were found: an early process affected by physical factors such as adapting luminance and a later process affected by attentional factors such as set size. This later process is called (...) masking by object substitution, because it occurs whenever there is a mismatch between the reentrant visual representation and the ongoing lower level activity. Iterative reentrant processing was formalized in a computational model that provides an excellent fit to the data. The model provides a more comprehensive account of all forms of visual masking than do the long-held feed-forward views based on inhibitory contour interactions. (shrink)

The rise of experimental philosophy has placed metaphilosophical questions, particularly those concerning concepts, at the center of philosophical attention. X-phi offers empirically rigorous methods for identifying conceptual content, but what exactly it contributes towards evaluating conceptual content remains unclear. We show how x-phi complements Rudolf Carnap’s underappreciated methodology for concept determination, explication. This clarifies and extends x-phi’s positive philosophical import, and also exhibits explication’s broad appeal. But there is a potential problem: Carnap’s account of explication was limited to empirical and (...) logical concepts, but many concepts of interest to philosophers are essentially normative. With formal epistemology as a case study, we show how x-phi assisted explication can apply to normative domains. (shrink)

This paper argues for the diversification of university-level philosophy curricula. I defend the ideal of expansionist pluralism and connect it to metaphilosophical myopia – problematically limited or constrained visions of the range of forms taken by philosophy. Expansively pluralist curricula work to challenge metaphilosophical myopia and one of its costs, namely, a specific kind of hermeneutical injustice, perpetrated against the communities and traditions shaped by the occluded forms of philosophy.

Experiments are presented showing that visual search for Mueller-Lyer (ML) stimuli is based on complete configurations, rather than component segments. Segments easily detected in isolation were difficult to detect when embedded in a configuration, indicating preemption by low-level groups. This preemption—which caused stimulus components to become inaccessible to rapid search—was an all-or-nothing effect, and so could serve as a powerful test of grouping. It is shown that these effects are unlikely to be due to blurring by simple spatial filters at (...) early visual levels. It is proposed instead that they are due to more sophisticated processes that rapidly bind contour fragments into spatially-extended assemblies. These results support the view that rapid visual search cannot access the primitives formed at the earliest stages of visual processing; rather, it can access only higher-level, more ecologically-relevant structures.

Serious actualists take it that all properties are existence entailing. I present a simple puzzle about sentence tokens which seems to show that serious actualism is false. I then consider the most promising response to the puzzle. This is the idea that the serious actualist should take ordinary property-talk to contain an implicit existential presupposition. I argue that this approach does not work: it fails to generalise appropriately to all sentence types and tokens. In particular, it fails to capture the (...) right distinctions we ought to make between what I call _typographical sentence types_—an interesting and previously undiscussed class of fine-grained sentence types which are partially individuated by their typography, or how they look when written out.

Little is known with regard to the precise cognitive tools the self uses in acquiring and processing information about itself. In this article, we underline the possibility that inner speech might just represent one such cognitive process. Duval and Wicklund’s theory of self-awareness and the selfconsciousness, and self-knowledge body of work that was inspired by it are reviewed, and the suggestion is put forward that inner speech parallels the state of self-awareness, is more frequently used among highly self-conscious persons, and (...) represents an effective, if not indispensable, tool involved in the formation of the self-concept. The possibility is also raised that the extent to which one uses inner speech could partially explain individual differences in self-consciousness and self-knowledge. A selective review of the private and inner speech literature is presented, and some possible ways of testing the hypothesis by using pre-existing techniques are proposed in the hope of stimulating empirical investigations. Some implications are outlined in conclusion. (shrink)

According to a traditional Cartesian epistemology of perception, perception does not provide one with direct knowledge of the external world. Instead, your immediate perceptual evidence is limited to facts about your own visual experience, from which conclusions about the external world must be inferred. Cartesianism faces well-known skeptical challenges. But this chapter argues that any anti-Cartesian view strong enough to avoid these challenges must license a way of updating one’s beliefs in response to anticipated experiences that seems diachronically irrational. To (...) avoid this result, the anti-Cartesian must either license an unacceptable epistemic chauvinism, or else claim that merely reflecting on one’s experiences defeats perceptual justification. This leaves us with a puzzle: Although Cartesianism faces problems, avoiding them brings a new set of problems. (shrink)

In a series of articles, Dan Lopez De Sa and Elia Zardini argue that several theorists have recently employed instances of paradoxical reasoning, while failing to see its problematic nature because it does not immediately (or obviously) yield inconsistency. In contrast, Lopez De Sa and Zardini claim that resultant inconsistency is not a necessary condition for paradoxicality. It is our contention that, even given their broader understanding of paradox, their arguments fail to undermine the instances of reasoning they attack, either (...) because they fail to see everything that is at work in that reasoning, or because they misunderstand what it is that the reasoning aims to show.

This chapter explores the idea that phylogenetic diversity plays a unique role in underpinning conservation endeavour. The conservation of biodiversity is suffering from a rapid, unguided proliferation of metrics. Confusion is caused by the wide variety of contexts in which we make use of the idea of biodiversity. Characterisations of biodiversity range from all-variety-at-all-levels down to variety with respect to single variables relevant to very specific conservation contexts. Accepting biodiversity as the sum of a large number of individual measures results (...) in an empirically intractable framework. However, large-scale decisions cannot be based on biodiversity variables inferred from local conservation imperatives because the variables relevant to the many systems being compared would be incommensurate with one another. We therefore need some general conception of biodiversity that would make tractable such large-scale environmental decision-marking. We categorise the large array of strategies for the measurement of biodiversity into four broad groups for consideration as general measures of biodiversity. We compare common moral justifications for the conservation of biodiversity and conclude that some form of instrumental value is the most plausible justification for biodiversity conservation. Although this is often interpreted as a reliance on option value, we opt for a broadly consequentialist characterisation of biodiversity conservation. We conclude that the best justified general measure of biodiversity will be some form of phylogenetic diversity. (shrink)

Each of the standard outlooks in the philosophy of perception --phenomenalism, direct realism, indirect realism, scepticism -- has thus been viewed as Hume's own considered position in the eyes of informed commentators. I argue that Hume does not ascribe univocally to any one of the traditional stances in the philosophy of perception, nor does he leave us only a schizophrenic or 'mood' scepticism. Hume attempted to resolve the traditional philosophical problem (or perhaps more accurately, to set it aside on principled (...) grounds) by transforming the issue from one of theoretical consistency to one of pragmatic coherence. Hume's moderate scepticism and his systematic naturalism entail a reflective 'return' to the vulgar (cp. T 223), a qualified normative endorsement of the directly realist beliefs of common life. The interpretive challenge is to understand the subtle nature of that endorsement, and to explain how it arises out of genuinely Humean doctrines. The account offered here attempts both to capture Hume's own considered position and to explain the attractions and shortcomings of each of the competing interpretations. After laying out the elements of Hume's account of perceptual belief (section I), I proceed to examine in some detail two recent attempts to interpret Hume as a realist (sections II-III). I contend that these revisionary accounts ascribe unHumean doctrines to Hume. The interpretation of Hume as an irreducible 'mood' sceptic or as a phenomenalist are in that respect both closer to the mark, but Hume's reflective return to the vulgar has recast the nature of the problem and leaves us with a position that is not reflected in the more traditional interpretations (section IV).

The central hypothesis of the collaboration between Language and Computing (L&C) and the Institute for Formal Ontology and Medical Information Science (IFOMIS) is that the methodology and conceptual rigor of a philosophically inspired formal ontology greatly benefits application ontologies. To this end r®, L&C’s ontology, which is designed to integrate and reason across various external databases simultaneously, has been submitted to the conceptual demands of IFOMIS’s Basic Formal Ontology (BFO). With this project we aim to move beyond the level of (...) controlled vocabularies to yield an ontology with the ability to support reasoning applications. Our general procedure has been the implementation of a meta-ontological definition space in which the definitions of all the concepts and relations in LinKBase® are standardized in a framework of first-order logic. In this paper we describe how this standardization has already led to an improvement in the LinKBase® structure that allows for a greater degree of internal coherence than ever before possible. We then show the use of this philosophical standardization for the purpose of mapping external databases to one another, using LinKBase® as translation hub, with a greater degree of success than possible hitherto. We demonstrate how this offers a genuine advance over other application ontologies that have not submitted themselves to the demands of philosophical scrutiny. LinKBase® is one of the world’s largest applications-oriented medical domain ontologies, and BFO is one of the world’s first philosophically driven reference ontologies. The collaboration of the two thus initiates a new phase in the quest to solve the so-called “Tower of Babel”. (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)

THE CASE FOR GOVERNMENT BY ARTIFICIAL INTELLIGENCE. Tired of election madness? The rhetoric of politicians? Their unreliable promises? And less than good government? -/- Until recently, it hasn’t been hard for people to give up control to computers. Not very many people miss the effort and time required to do calculations by hand, to keep track of their finances, or to complete their tax returns manually. But relinquishing direct human control to self-driving cars is expected to be more of a (...) challenge, despite the predicted decrease in vehicle accidents thanks to artificial intelligence that isn’t subject to human distractions and errors of judgment. -/- If turning vehicle control over to artificial intelligence is a challenge, it is a very mild one compared with the idea that we might one day recognize and want to implement the advantages of human government by AI. But, like autonomous vehicle control, government by AI is likely to offer decided benefits. -/- In other publications, the author has studied a variety of widespread human limitations that, throughout human history, have led to much human suffering as well as ecological destruction. For the first time, these psychological and cognitive human shortcomings are taken into account in an essay that makes the case for government by artificial intelligence. (shrink)

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)

[A Polish translation of Steven James Bartlett, “Phenomenology of the Implicit,” Dialectica: Revue international de philosophie de la connaissance, Vol. 29, Nos. 2-3, 1975, pp. 173-188.] -/- This paper marks a juncture between the author’s studies in phenomenology and the transition he made to a study of what he has called a “metalogic of reference.” Published in 1974 in Polish translation, followed by its publication in English in 1975, “Phenomenology of the Implicit” describes the author’s “translation schema” that permits (...) certain of the central goals of Husserlian transcendental philosophy to be transposed to a framework that studies the preconditions of valid reference. The result of this translation was the development of the author’s “de-projective” approach to phenomenology, which he later dissociated from phenomenology in the form of a pure metalogic of reference.

In this essay, I look at two negative portrayals of egoism. I summarize in detail the superb All About Eve—which won six Academy Awards, including Best Picture. The movie is about the rise of a ruthlessly ambitious actress, and how she treats her main competitor. Eve Harrington worms her way into top theatrical actress Margo Channing’s inner circle by pretending to be an admirer, but she is really a schemer who wants to eclipse Margo’s star in the theater universe. However, (...) Eve runs into trouble when she attempts to manipulate tart-tongued theater critic, Addison de Witt. The movie portrays the New York theater industry as being full of narcissists. I then review the classic film noir The Third Man (1949), rated by the prestigious British Film Institute as the greatest film of the 20th century. The film centers around a charismatic, handsome criminal mastermind Harry Lime living in bombed-out post-War Vienna. Lime is a man of no conscience or empathy—a true psychopath. He cripples children by selling hospitals adulterated penicillin. But we (the audience) still feel sympathy for him. I end the piece by explaining the psychological mechanisms at work that give rise to our paradoxical sympathy. (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)

We show how an epistemology informed by cognitive science promises to shed light on an ancient problem in the philosophy of mathematics: the problem of exactness. The problem of exactness arises because geometrical knowledge is thought to concern perfect geometrical forms, whereas the embodiment of such forms in the natural world may be imperfect. There thus arises an apparent mismatch between mathematical concepts and physical reality. We propose that the problem can be solved by emphasizing the ways in which the (...) brain can transform and organize its perceptual intake. It is not necessary for a geometrical form to be perfectly instantiated in order for perception of such a form to be the basis of a geometrical concept. (shrink)

In this essay, I look at more or less sympathetic portrayals of egoists in film. I start by explaining some basic concepts: psychological egoism; ethical egoism; default egoism; rational egoism; egotism; cynicism; narcissism; and psychopathy. I then review in-depth two excellent WWII films, Stalag 17 and The Bridge on the River Kwai. I note that the key protagonist in both pictures is the same type of character—both played by the same fine actor, William Holden. The main protagonist in both is (...) a soldier in a POW camp, who appears completely egoistic; however, in both cases, the movie shows that he is just a man acting for self-preservation, but within moral limits. The character in both cases is certainly not an egotist, nor a narcissist, much less a psychopath. (shrink)

This essay is my critical review of Al Gini and Alexei Marcoux’s fine text, The Ethics of Business. Unlike most business ethics texts, Gini/Marcoux recognize that most businesses are small, and that business is not inherently immoral and always in need of reform. And they put their focus on using ethical theory to find action-guiding principles to help guide business behavior. Moreover, they adopt the Schumpeterian view that business is an entrepreneurial activity—one that not merely executes transactions, but seeks them (...) out. I critically probe a number of issues with their book such as their reliance upon virtue ethics as their main ethical theory, and their view that trust plays an overwhelming role in business.

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)

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 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.

Formal semantic analyses often take words to be minimal building blocks for the purposes of compositionality. But various recent theories of morphology and syntax have converged on the view that there is no demarcation line corresponding to the word level. The same conclusion has emerged from the compositional semantics of superlatives. In the spirit of extending compositionality below the word level, this paper explores how a small set of particles (Japanese KA and MO, Chinese DOU, and Hungarian VALA/VAGY, MIND, and (...) IS) form quantifier words and serve as connectives, additive and scalar particles, question markers, and existential verbs. The main question is whether the meanings of these particles across the varied environments are highly regular, or they are lexicalized with a variety of different meanings that bear a family resemblance. This paper does not reach definitive conclusions, but it raises analytical possibilities using Boolean semantics and the semantics of alternatives. It also draws attention to systematic similarities and some differences between MO and DOU that have not been studied in the literature. (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.

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)

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? 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)

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.

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.

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.

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)

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.

The philosophical interest of mystery is that something may well fall under a distinctive ontological concept of mystery. Such a thing would be explicable with reference to intention, but not uniquely determined by its explicans. This is the "properly mysterious," which is essentially mysterious in virtue of what it is, not just of our epistemic limitations. The richer uses of 'mystery', and defects in recent literature, suggest this line of inquiry. ;Part I rebuts the main arguments against the possibility that (...) something is properly mysterious. First, if something's existence is completely explicable it need not thus be exhaustively explicable . Second, event-determinism is not establishable empirically and nothing establishes general determinism a priori . So there is no reason to think every existent is uniquely determined to exist. But there is good reason to think everything is completely explicable in principle. ;Part II shows there is better reason to think the world's existence properly mysterious than not. The world asked about in the question "Why does the world exist?" should be defined as the totality comprising all that really changes and what is ontologically parasitic thereon . The World's existence is both logically contingent and contingent in one or the other of two de re senses , and thus is either inexplicable for any knower or explicable as intentionally produced. The producer would be extramundane, de re necessary, and could not uniquely determine the existence of The World. Defending classical theism against charges of conceptual incoherence, I conclude that the existence of The World is best thought completely explicable as intentionally created, though not exhaustively explicable by the existence of its creator. ;In conclusion, I expound and adopt Aquinas' account of creation, on which God creates for a reason and freely. Thus there is good reason for the world's existence, but no reason why this world exists rather than some other. (shrink)

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)

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)

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)
