We consider the current debate between bioconservatives and their opponents—whom we dub bioliberals—about the moral acceptability of human enhancement and the policy implications of moral debates about enhancement. We argue that this debate has reached an impasse, largely because bioconservatives hold that we should honour intuitions about the special value of being human, even if we cannot identify reasons to ground those intuitions. We argue that although intuitions are often a reliable guide to belief and action, there are circumstances in (...) which they are not reliable. Intuitions—including intuitions about enhancement—are subject to various cognitive biases rendering them unreliable in some circumstances. We argue that many bioconservative intuitions about enhancement are examples of such unreliable intuitions. Given this, it is unrealistic of bioconservatives to expect others to rely on their unexamined intuitions. Furthermore, refusing to engage in debates about the reasons and values that underpin their intuitions about enhancement will have the effect of making bioconservative voices less relevant in policy debates about enhancement than they would otherwise be.

A book review of Steve Clark's The Justification of Religious Violence.

Steve Clarke, Nathan Emmerich, Francesca Minerva and Toni Saad have offered nuanced and insightful commentaries on my paper ‘The truth behind conscientious objection in medicine’.1 I cannot, in this brief response, do justice to all of the objections and suggestions that they have raised. I have tried to focus my response on what I take to be my interlocutors’ main concerns with my Smithian account, with the hope that we can continue the conversation elsewhere. Clarke argues that (...) both Smith and I ‘underestimate the difficulties involved in overcoming the distorting influence of “self-love” on moral judgement’ and ‘fail to recognise how easy it is for us to mistake a self-interested view for an impartial one’.2 His thought is that cognitive bias and ideological commitments will prevent many of us from identifying the standpoint of the impartial spectator and from realising that we are not impartial.1 I agree that successfully adopting the standpoint of the impartial spectator is not an easy task. However, moral reasoning more generally is difficult and susceptible to bias. This does not mean that we should cease such reasoning; rather, we ought to do our best, and we are, at times, successful. Clarke discusses the entrenched attitudes of Antebellum white racists. However, attitudes about slavery have changed, and cognitive biases can change too. In other words, moral progress is possible. Moreover, as I argue in the paper, one of the advantages of the impartial-spectator approach is that it ‘provides a standpoint from which shared deliberation is possible and public reasons are available’.1 Thus, we can appreciate, with relative ease, whether an objector is reasoning from this standpoint. Clarke further argues that we should entertain the idea of employing ‘experts who are trained to overcome cognitive bias and to set aside ideological commitments’ and …. (shrink)

I argue for patternism, a new answer to the question of when some objects compose a whole. None of the standard principles of composition comfortably capture our natural judgments, such as that my cat exists and my table exists, but there is nothing wholly composed of them. Patternism holds, very roughly, that some things compose a whole whenever together they form a “real pattern”. Plausibly we are inclined to acknowledge the existence of my cat and my table but not of (...) their fusion, because the first two have a kind of internal organizational coherence that their putative fusion lacks. Kolmogorov complexity theory supplies the needed rigorous sense of “internal organizational coherence”. (shrink)

This is a three-part exchange on the relationship between belief and credence. It begins with an opening essay by Roger Clarke that argues for the claim that the notion of credence generalizes the notion of belief. Julia Staffel argues in her reply that we need to distinguish between mental states and models representing them, and that this helps us explain what it could mean that belief is a special case of credence. Roger Clarke's final essay reflects on the (...) compatibility of the previously discussed views with dualist and monist interpretations of our mental states and our ways of modeling them. (shrink)

Nick Bostrom's book *Superintelligence* outlines a frightening but realistic scenario for human extinction: true artificial intelligence is likely to bootstrap itself into superintelligence, and thereby become ideally effective at achieving its goals. Human-friendly goals seem too abstract to be pre-programmed with any confidence, and if those goals are *not* explicitly favorable toward humans, the superintelligence will extinguish us---not through any malice, but simply because it will want our resources for its own purposes. In response I argue that things might not (...) be as bad as Bostrom suggests. If the superintelligence must *learn* complex final goals, then this means such a superintelligence must in effect *reason* about its own goals. And because it will be especially clear to a superintelligence that there are no sharp lines between one agent's goals and another's, that reasoning could therefore automatically be ethical in nature.

Jennifer Blumenthal-Barby (2024) has called for bioethics to end talk about personhood, asserting that such talk has the tendency to confuse and offend. It will be argued that this has only limited application for (largely) private settings. However, in other settings, theorizing about personhood leaves a gap in which there is the risk that the offending concept will get uptake elsewhere, and so the problem Blumenthal-Barby nominates may not be completely avoided. In response to this risk, an argument is presented (...) in support of the idea that the role of philosophers and bioethicists, far from ending talk of personhood, ought to be to clarify the concept, and to do so in nuanced ways, given its application for specific kinds of impairments. The case of dementia is used to illustrate this in the context of person-centered care. Ironically, given the stigma attached to dementia, far from the need to end talk of personhood, bioethicists are needed to rescue the concept and clarify its role. (shrink)

It is widely agreed that the intelligibility of modal metaphysics has been vindicated. Quine's arguments to the contrary supposedly confused analyticity with metaphysical necessity, and rigid with non-rigid designators.2 But even if modal metaphysics is intelligible, it could be misconceived. It could be that metaphysical necessity is not absolute necessity – the strictest real notion of necessity – and that no proposition of traditional metaphysical interest is necessary in every real sense. If there were nothing otherwise “uniquely metaphysically significant” about (...) metaphysical necessity, then paradigmatic metaphysical necessities would be necessary in one sense of “necessary”, not necessary in another, and that would be it. The question of whether they were necessary simpliciter would be like the question of whether the Parallel Postulate is true simpliciter – understood as a pure mathematical conjecture, rather than as a hypothesis about physical spacetime. In a sense, the latter question has no objective answer. In this article, I argue that paradigmatic questions of modal metaphysics are like the Parallel Postulate question. I then discuss the deflationary ramifications of this argument. I conclude with an alternative conception of the space of possibility. According to this conception, there is no objective boundary between possibility and impossibility. Along the way, I sketch an analogy between modal metaphysics and set theory. (shrink)

Hohwy (Hohwy 2016, Hohwy 2017) argues there is a tension between the free energy principle and leading depictions of mind as embodied, enactive, and extended (so-called ‘EEE1 cognition’). The tension is traced to the importance, in free energy formulations, of a conception of mind and agency that depends upon the presence of a ‘Markov blanket’ demarcating the agent from the surrounding world. In what follows I show that the Markov blanket considerations do not, in fact, lead to the kinds of (...) tension that Hohwy depicts. On the contrary, they actively favour the EEE story. This is because the Markov property, as exemplified in biological agents, picks out neither a unique nor a stationary boundary. It is this multiplicity and mutability– rather than the absence of agent-environment boundaries as such - that EEE cognition celebrates. (shrink)

On a now orthodox view, humans and many other animals possess a “number sense,” or approximate number system, that represents number. Recently, this orthodox view has been subject to numerous critiques that question whether the ANS genuinely represents number. We distinguish three lines of critique – the arguments from congruency, confounds, and imprecision – and show that none succeed. We then provide positive reasons to think that the ANS genuinely represents numbers, and not just non-numerical confounds or exotic substitutes for (...) number, such as “numerosities” or “quanticals,” as critics propose. In so doing, we raise a neglected question: numbers of what kind? Proponents of the orthodox view have been remarkably coy on this issue. But this is unsatisfactory since the predictions of the orthodox view, including the situations in which the ANS is expected to succeed or fail, turn on the kind of number being represented. In response, we propose that the ANS represents not only natural numbers, but also non-natural rational numbers. It does not represent irrational numbers, however, and thereby fails to represent the real numbers more generally. This distances our proposal from existing conjectures, refines our understanding of the ANS, and paves the way for future research. (shrink)

Whether it would take one decade or several centuries, many agree that it is possible to create a *superintelligence*---an artificial intelligence with a godlike ability to achieve its goals. And many who have reflected carefully on this fact agree that our best hope for a "friendly" superintelligence is to design it to *learn* values like ours, since our values are too complex to program or hardwire explicitly. But the value learning approach to AI safety faces three particularly philosophical puzzles: first, (...) it is unclear how any intelligent system could learn its final values, since to judge one supposedly "final" value against another seems to require a further background standard for judging. Second, it is unclear how to determine the content of a system's values based on its physical or computational structure. Finally, there is the distinctly ethical question of which values we should best aim for the system to learn. I outline a potential answer to these interrelated puzzles, centering on a "miktotelic" proposal for blending a complex, learnable final value out of many simpler ones. (shrink)

It is widely alleged that metaphysical possibility is “absolute” possibility Conceivability and possibility, Clarendon, Oxford, 2002, p 16; Stalnaker, in: Stalnaker Ways a world might be: metaphysical and anti-metaphysical essays, Oxford University Press, Oxford, 2003, pp 201–215; Williamson in Can J Philos 46:453–492, 2016). Kripke calls metaphysical necessity “necessity in the highest degree”. Van Inwagen claims that if P is metaphysically possible, then it is possible “tout court. Possible simpliciter. Possible period…. possib without qualification.” And Stalnaker writes, “we can agree (...) with Frank Jackson, David Chalmers, Saul Kripke, David Lewis, and most others who allow themselves to talk about possible worlds at all, that metaphysical necessity is necessity in the widest sense.” What exactly does the thesis that metaphysical possibility is absolute amount to? Is it true? In this article, I argue that, assuming that the thesis is not merely terminological, and lacking in any metaphysical interest, it is an article of faith. I conclude with the suggestion that metaphysical possibility may lack the metaphysical significance that is widely attributed to it. (shrink)

In this chapter I'd like to focus on a small corner of sexbot ethics that is rarely considered elsewhere: the question of whether and when being a sexbot might be good---or bad---*for the sexbot*. You might think this means you are in for a dry sermon about the evils of robot slavery. If so, you'd be wrong; the ethics of robot servitude are far more complicated than that. In fact, if the arguments here are right, designing a robot to serve (...) humans sexually may be very good for the robots themselves. (shrink)

To identify and conceptualize research problems in science, philosophers and often scientists rely on classical accounts of problems that focus on intellectual problems defined in relation to theories. Recently, philosophers have begun to study the structures and functions of research problems not defined in relation to theories. Furthermore, scientists have long pursued research problems often labeled as practical or applied. As yet, no account of problems specifies the description of both so-called intellectual problems and so-called applied problems. This article proposes (...) a new conceptual framework of problems that accounts both for intellectual aspects of problems and for their practical or applied aspects. I illustrate the account with an example of a recent research project from evolutionary biology, and I indicate further routes by that to develop the account, especially in connection to empirical studies of science.

The distinction between perception and cognition frames countless debates in philosophy and cognitive science. But what, if anything, does this distinction actually amount to? In this introductory article, we summarize recent work on this question. We first briefly consider the possibility that a perception-cognition border should be eliminated from our scientific ontology, and then introduce and critically examine five positive approaches to marking a perception–cognition border, framed in terms of phenomenology, revisability, modularity, format, and stimulus-dependence.

Soofi1 aims to develop an account of dignity in dementia care based on Nussbaum’s capabilities approach. He does this by drawing on the Kitwood and Bredin2 list of well-being indicators, in order to fill out her account of human flourishing to cover aspects such as practical reasoning that appear beyond the reach of those with relatively severe dementia. As Soofi points out, Nussbaum’s claim that such lost abilities can be compensated through guardianship measures is implausible. He asserts in response that (...) his account of dignity is sufficient to address the desiderata he sets out at the start, including especially the problem of exclusionary implications any putative account should address. So far, so good, but an objection Soofi raises for his own account is that it seems unable to cover cases of severe late-stage dementia. His response is, > …that there is insufficient factual evidence to suggest that people at the very advanced stages of dementia lose all capabilities. But for the sake of argument, let’s suppose that this is true. This, however, still does not undermine the conceptual rigour of the modified version of Nussbaum’s account. This is because the list of the dementia-specific capabilities that I …. (shrink)

This is a draft of the introduction to a forthcoming volume that brings together all of J. G. Herder's student notes from Immanuel Kant's lectures. It is intended as a volume in Kant's gesammelte Schriften (de Gruyter). These are the earliest notes (1762-64) we have from Kant's lectures (which span from 1755 to 1796) and the only notes before his professorship began in 1770. Included are improved transcriptions of Herder's notes on metaphysics, moral philosophy, logic, physics, and mathematics, and the (...) first transcription of his notes from Kant’s physical geography lectures.

Despite Kant's belief in a universal causal determinism among phenomena and his rejection of any noumenal agency in brutes, he nevertheless rejected Descartes's hypothesis that brutes are machines. Explaining Kant's response to Descartes forms the basis for this discussion of the nature of consciousness and matter in Kant's system. Kant's numerous remarks on animal psychology-as found in his lecture notes and reflections on metaphysics and anthropology-suggest a theory of consciousness and self-consciousness at odds with that traditionally ascribed to him.

I argue that, contrary to intuition, it would be both possible and permissible to design people - whether artificial or organic - who by their nature desire to do tasks we find unpleasant.

It is often claimed that pre-attentive vision has an ‘iconic’ format. This is seen to explain pre-attentive vision's characteristically high processing capacity and to make sense of an overlap in the mechanisms of early vision and mental imagery. But what does the iconicity of pre-attentive vision amount to? This paper considers two prominent ways of characterising pre-attentive visual icons and argues that neither is adequate: one approach renders the claim ‘pre-attentive vision is iconic’ empirically false while the other obscures its (...) ability to do the explanatory work, which motivates positing pre-attentive visual icons in the first place. With this noted, I introduce the notion of an ‘Analogue Map’ and argue that it provides a superior characterisation of pre-attentive vision's iconicity. I then argue that this forces a reassessment of debates which have traditionally presupposed the iconicity of pre-attentive vision, emphasising ramifications for the viability of a format-based perception-thought border.

_ Source: _Page Count 22 Analysis of the concept of habit has been relatively neglected in the contemporary analytic literature. This paper is an attempt to rectify this lack. The strategy begins with a description of some paradigm cases of habit which are used to derive five features as the basis for an explicative definition. It is argued that habits are social, acquired through repetition, enduring, environmentally activated, and automatic. The enduring nature of habits is captured by their being dispositions (...) of a certain sort. This is a realist account of habits insofar as the dispositions put forward must fit into some recognizable underlying system – in the case of humans a biological system – to fill the role as set out by the definition. This role is wide-ranging; in addition to the familiar cases of habitual behavior, habitual activities also include thinking, perceiving, feeling, and willing. (shrink)

The blameworthy deserve blame. So runs a platitude of commonsense morality. My aim here is to set out an understanding of this desert claim (as I call it) on which it can be seen to be a familiar and attractive aspect of moral thought. I conclude with a response to a prominent denial of the claim.

Standard epistemology takes it for granted that there is a special kind of value: epistemic value. This claim does not seem to sit well with act utilitarianism, however, since it holds that only welfare is of real value. I first develop a particularly utilitarian sense of “epistemic value”, according to which it is closely analogous to the nature of financial value. I then demonstrate the promise this approach has for two current puzzles in the intersection of epistemology and value theory: (...) first, the problem of why knowledge is better than mere true belief, and second, the relation between epistemic justification and responsibility.

A growing number of philosophers now hold that agent causation is required for agency, or free will, or moral responsibility. To clarify what is at issue, this paper begins with a distinction between agent causation that is ontologically fundamental and agent causation that is reducible to or realized in causation by events or states. It is widely accepted that agency presents us with the latter; the view in question claims a need for the former. The paper then examines a “disappearing (...) agent” argument from Derk Pereboom that is aimed at showing that free will requires agent causation that is ontologically fundamental. It is argued that the argument fails. Further, it is argued that, contrary to Pereboom’s claim, the issue raised by his disappearing agent argument is distinct from the problem of present luck that libertarian theories of free will face. The paper concludes with an assessment of the prospects for success of a disappearing agent argument showing that agent causation that is ontologically fundamental is required for agency tout court.

Set-theoretic pluralism is an increasingly influential position in the philosophy of set theory (Balaguer [1998], Linksy and Zalta [1995], Hamkins [2012]). There is considerable room for debate about how best to formulate set-theoretic pluralism, and even about whether the view is coherent. But there is widespread agreement as to what there is to recommend the view (given that it can be formulated coherently). Unlike set-theoretic universalism, set-theoretic pluralism affords an answer to Benacerraf’s epistemological challenge. The purpose of this paper is (...) to determine what Benacerraf’s challenge could be such that this view is warranted. I argue that it could not be any of the challenges with which it has been traditionally identified by its advocates, like of Benacerraf and Field. Not only are none of the challenges easier for the pluralist to meet. None satisfies a key constraint that has been placed on Benacerraf’s challenge. However, I argue that Benacerraf’s challenge could be the challenge to show that our set-theoretic beliefs are safe – i.e., to show that we could not have easily had false ones. Whether the pluralist is, in fact, better positioned to show that our set-theoretic beliefs are safe turns on a broadly empirical conjecture which is outstanding. If this conjecture proves to be false, then it is unclear what the epistemological argument for set-theoretic pluralism is supposed to be. (shrink)

This paper argues for a treatment of belief as essentially sensitive to certain features of context. The first part gives an argument that we must take belief to be context-sensitive in the same way that assertion is, if we are to preserve appealing principles tying belief to sincere assertion. In particular, whether an agent counts as believing that p in a context depends on the space of alternative possibilities the agent is considering in that context. One and the same doxastic (...) state may amount to belief that p in one context but not another. The second part of the paper gives a formal treatment of doxastic states, according to which belief is context-sensitive along just these lines. The model is applied to characterize (but not to refute) skeptical arguments. (shrink)

I am grateful to Sean Carroll, Paul Horwich, and Sarah McGrath for their stimulating responses to Morality and Mathematics (M&M). Their arguments concern the reality of unapplied mathematics, the practical import of moral facts, and the deliberative and explanatory roles of evaluative theories. In what follows, I address their responses, as well as some broader issues.

There are writers in both metaphysics and algorithmic information theory (AIT) who seem to think that the latter could provide a formal theory of the former. This paper is intended as a step in that direction. It demonstrates how AIT might be used to define basic metaphysical notions such as *object* and *property* for a simple, idealized world. The extent to which these definitions capture intuitions about the metaphysics of the simple world, times the extent to which we think the (...) simple world is analogous to our own, will determine a lower bound for basing a metaphysics for *our* world on AIT.

Jerry Fodor deemed informational encapsulation ‘the essence’ of a system’s modularity and argued that human perceptual processing comprises modular systems, thus construed. Nowadays, his conclusion is widely challenged. Often, this is because experimental work is seen to somehow demonstrate the cognitive penetrability of perceptual processing, where this is assumed to conflict with the informational encapsulation of perceptual systems. Here, I deny the conflict, proposing that cognitive penetration need not have any straightforward bearing on the conjecture that perceptual processing is composed (...) of nothing but informationally encapsulated modules, the conjecture that each and every perceptual computation is performed by an informationally encapsulated module, and the consequences perceptual encapsulation was traditionally expected to have for a perception-cognition border, the epistemology of perception and cognitive science. With these points in view, I propose that particularly plausible cases of cognitive penetration would actually seem to evince the encapsulation of perceptual systems rather than refute/problematize this conjecture.

The complexity that we observe in nature can often be explained in terms of cooperative behavior. For example, the major transitions of evolution required the emergence of cooperation among the lower-level units of selection, which led to specialization through division-of-labor ultimately resulting in spontaneous order. There are two aspects to address explaining how such cooperation is sustained: how free-riders are prevented from free-riding on the benefits of cooperative tasks, and just as importantly, how those social benefits arise. We review these (...) problems from an economic perspective, and highlight how ideas from economics can help us to better understand how the benefits of social interactions arise, how they are sustained, and how they affect the underlying social dilemmas.

Over the last century within the philosophy of mind, the intersubjective model of self has gained traction as a viable alternative to the oft-criticised Cartesian solipsistic paradigm. These two models are presented as incompatible inasmuch as Cartesians perceive other minds as “a problem” for the self, while intersubjectivists insist that sociality is foundational to selfhood. This essay uses the Paranormal Activity series (2007–2015) to explore this philosophical debate. It is argued that these films simultaneously evoke Cartesian premises (via found-footage camerawork), (...) and intersubjectivity (via an ongoing narrative structure that emphasises connections between the characters, and between each film). The philosophical debates illuminate premises on which the series’ story and horror depends. Moreover, Paranormal Activity also sheds light on the theoretical debate: the series brings those two paradigms together into a coherent whole, thereby suggesting that the two models are potentially compatible. By developing a combined model, scholars working in the philosophy of mind might better account for the different aspects of self-experience these paradigms focus on. (shrink)

Benjamin Matheson has recently argued that blameworthiness is terminable: in at least some cases, one's blameworthiness for a given offense can be diminished or even eliminated. Although Matheson presents a forceful challenge to those who deny this view—interminability theorists, he calls them—he misconstrues their position and fails to come to grips with several considerations that favor it. This paper aims to clarify key aspects of the debate and defend the claim that blameworthiness is interminable.

This paper refines a controversial proposal: that core systems belong to a perceptual kind, marked out by the format of its representational outputs. Following Susan Carey, this proposal has been understood in terms of core representations having an iconic format, like certain paradigmatically perceptual outputs. I argue that they don’t, but suggest that the proposal may be better formulated in terms of a broader analogue format type. Formulated in this way, the proposal accommodates the existence of genuine icons in perception, (...) and avoids otherwise troubling objections. (shrink)

Logical monism is the view that there is ‘One True Logic’. This is the default position, against which pluralists react. If there were not ‘One True Logic’, it is hard to see how there could be one true theory of anything. A theory is closed under a logic! But what is logical monism? In this article, I consider semantic, logical, modal, scientific, and metaphysical proposals. I argue that, on no ‘factualist’ analysis (according to which ‘there is One True Logic’ expresses (...) a factual claim, rather than an attitude like approval), does the doctrine have both metaphysical and methodological import. Metaphysically, logics abound. Methodologically, what to infer from what is not settled by the facts, even the normative ones. I conclude that the only interesting sense in which there could be One True Logic is noncognitive. The same may be true of monism about normative areas, like moral, epistemic, and prudential ones, generally. (shrink)

This paper explores the implications of libertarianism for welfare policy. There are two central arguments. First, the paper argues that if one adopts a libertarian framework, it makes most sense to be a Lockean right-libertarian. Second, the paper argues that this form of libertarianism leads to the endorsement of a fairly extensive set of redistributive welfare programs. Specifically, the paper argues that Lockean right-libertarians are committed to endorsing welfare programs under which the receipt of benefits is conditional on meeting a (...) work requirement, and also endorsing some form of publicly funded jobs of last resort for potential welfare recipients.

A "patternist" approach to explanation seeks to formalize unificationism using notions from algorithmic information theory.

It has been claimed that naïve realism predicts phenomenological similarities where there are none and, thereby, mischaracterises the phenomenal character of perceptual experience. If true, this undercuts a key motivation for the view. Here, we defend naïve realism against this charge, proposing that such arguments fail (three times over). In so doing, we highlight a more general problem with critiques of naïve realism that target the purported phenomenological predictions of the view. The problem is: naïve realism, broadly construed, doesn’t make (...) phenomenological predictions of the required sort. So, as a result, opponents must resign themselves to attacking specific incarnations of naïve realism, or approach matters quite differently. (shrink)

Number Nativism is the view that humans innately represent precise natural numbers. Despite a long and venerable history, it is often considered hopelessly out of touch with the empirical record. I argue that this is a mistake. After clarifying Number Nativism and distancing it from related conjectures, I distinguish three arguments which have been seen to refute the view. I argue that, while popular, two of these arguments miss the mark, and fail to place pressure on Number Nativism. Meanwhile, a (...) third argument is best construed as a challenge: rather than refuting Number Nativism, it challenges its proponents to provide positive evidence for their thesis and show that this can be squared with apparent counterevidence. In response, I introduce psycholinguistic work on The Tolerance Principle (not yet considered in this context), propose that it is hard to make sense of without positing precise and innate representations of natural numbers, and argue that there is no obvious reason why these innate representations couldn’t serve as a basis for mature numeric conception.

The combination of sex and horror may be disquieting to many, but the two are natural (if perhaps gruesome) bedfellows. In fact, sex and horror coincide with such regularity in contemporary horror fiction that the two concepts appear to be at least partially intertwined. The sex–horror relationship is sometimes connotative rather than overt; examples of this relationship range from the seduction overtones of 'Nosferatu' and the juxtaposition of nudity and horror promised by European exploitation filmmakers to the sadomasochistic iconography of (...) 'Hellraiser'. In other cases, sex and horror are balanced in a manner that thoroughly blurs the distinction between porn and horror. The sustained presence of sex-horror in film suggests that these two elements fit together and the combination is a source of pleasure (entertainment, fascination, intellectual stimulation and so forth) for many. Yet sex-horror is broadly perceived to be disturbing and these negative reactions indicate that sex-horror is a source of trepidation, moral disdain or disgust for some. Thus, it appears that sex-horror inspires directly competing responses. One might conclude that sex-horror itself is paradoxical; that it holds two directly oppositional meanings simultaneously. However, as I will illustrate in this chapter, these dual responses are not as contradictory as they might first appear to be. (shrink)

A review of the the book Disability, Avoidance and the Academy.

I argue that analogue mental representations possess a canonical decomposition into privileged constituents from which they compose. I motivate this suggestion, and rebut arguments to the contrary, through reflection on the approximate number system, whose representations are widely expected to have an analogue format. I then argue that arguments for the compositionality and constituent structure of these analogue representations generalize to other analogue mental representations posited in the human mind, such as those in early vision and visual imagery.

In his influential book, The Nature of Morality, Gilbert Harman writes: “In explaining the observations that support a physical theory, scientists typically appeal to mathematical principles. On the other hand, one never seems to need to appeal in this way to moral principles.” What is the epistemological relevance of this contrast, if genuine? This chapter argues that ethicists and philosophers of mathematics have misunderstood it. They have confused what the chapter calls the justificatory challenge for realism about an area, D—the (...) challenge to justify our D-beliefs—with the reliability challenge for D-realism—the challenge to explain the reliability of our D-beliefs. Harman’s contrast is relevant to the first, but not, evidently, to the second. One upshot of the discussion is that genealogical debunking arguments are fallacious. Another is that indispensability considerations cannot answer the Benacerraf–Field challenge for mathematical realism. (shrink)

Holly Smith has done more than anyone to explore and defend the importance of usability for moral theories. In Making Morality Work, she develops a moral theory that is almost universally usable. But not quite. In this article, I argue that no moral theory is universally usable, in the sense that is most immediately relevant to action, even by agents who know all the normative facts. There is no moral theory knowledge of which suffices to settle deliberation about what to (...) do. However, this is unsurprising if the question of what to do is not a question of fact. One upshot of the discussion is that the search for a universally usable moral theory is misconceived. Another is that, contra Smith (341), agents who are radically uncertain need not lack autonomy.

Though famously Derek Parfit is known for his reductionism about persons, he does, in fact, also profess a form of realism about persons based on the way the language of persons and personal identity is used. We might say that Parfit is an ontological reductionist about persons but not a conceptual reductionist. In this discussion note I try to bring out a difficulty for this kind of hybrid view by showing that there are many ways – too many in fact (...) – in which we use the language of persons and personal identity that cannot be reconciled with the core of Parfitian ontological reductionism. If it is true that the kind of reconciliation Parfit and his followers assent to is untenable, then a stark choice is presented between reductionism and a repudiation of most, if not all vestiges of realism. A genuine reductionist ought to choose against the latter. (shrink)
