In this paper, I explore risks and responsibilities associated with speaking for others. I argue that, contrary to the recent philosophical literature on the subject, speaking for others is not always epistemically or politically illegitimate. Moreover, epistemological justification is not the only important consideration when trying to determine if we should speak for others. Ethical justification also matters and can override epistemological worries. Indeed, sometimes we should speak for others though we cannot know their experience. I identify and evaluate five (...) kinds of speaking for others. I end by exploring some of the implications of my analysisfor social justice for women and girls internationally. (shrink)

Empirical evidence indicates that bereaved spouses are surprisingly muted in their responses to their loss, and that after a few months many of the bereaved return to their emotional baseline. Psychologists think this is good news: resilience is adaptive, and we should welcome evidence that there is less suffering in the world. I explore various reasons we might have for regretting our resilience, both because of what resilience tells us about our own significance vis-à-vis loved ones, and because resilience may (...) render us incapable of comprehending how things really stand, valuewise. I also compare our actual dispositions to extreme alternatives (“sub-resilience” and “super-resilience”), and consider whether we might endorse (plain) resilience as a kind of mean. (shrink)

In this chapter we focus on the debate over publicly-maintained racist monuments as it manifests in the mid-2010s Anglosphere, primarily in the US (chiefly regarding the over 700 monuments devoted to the Confederacy), but to some degree also in Britain and Commonwealth countries, especially South Africa (chiefly regarding monuments devoted to figures and events associated with colonialism and apartheid). After pointing to some representative examples of racist monuments, we discuss ways a monument can be thought racist, and neutrally categorize removalist (...) and preservationist arguments heard in the monument debate. We suggest that both extremist and moderate removalist goals are likely to be self-defeating, and that when concerns of civic sustainability are put on moral par with those of fairness and justice, something like a Mandela-era preservationist policy is best: one which removes the most offensive of the minor racist monuments, but which focuses on closing the monumentary gap between peoples and reframing existing racist monuments.

How should modern medicine's dramatic new powers to sustain life be employed? How should limited resources be used to extend and improve the quality of life? In this collection, Dan Brock, a distinguished philosopher and bioethicist and co-author of Deciding for Others (Cambridge, 1989), explores the moral issues raised by new ideals of shared decision making between physicians and patients. The book develops an ethical framework for decisions about life-sustaining treatment and euthanasia, and examines how these life and death decisions (...) are transformed in health policy when the focus shifts from what is best for a patient to what is just for all patients. Professor Brock combines acute philosophical analysis with a deep understanding of the realities of clinical health policy. This is a volume for philosophers concerned with medical ethics, health policy professionals, physicians interested in bioethics, and undergraduate courses in biomedical ethics. (shrink)

This book argues that political libertarianism can be grounded in widely shared, everyday moral beliefs--particularly in strictures against shifting our burdens onto others. It also seeks to connect these philosophical arguments with related work in economics, history, and politics for a wide-ranging discussion of political economy.

Some medical services have long generated deep moral controversy within the medical profession as well as in broader society and have led to conscientious refusals by some physicians to provide those services to their patients. More recently, pharmacists in a number of states have refused on grounds of conscience to fill legal prescriptions for their customers. This paper assesses these controversies. First, I offer a brief account of the basis and limits of the claim to be free to act on (...) one’s conscience. Second, I sketch an account of the basis of the medical and pharmacy professions’ responsibilities and the process by which they are specified and change over time. Third, I then set out and defend what I call the “conventional compromise” as a reasonable accommodation to conflicts between these professions’ responsibilities and the moral integrity of their individual members. Finally, I take up and reject the complicity objection to the conventional compromise. Put together, this provides my answer to the question posed in the title of my paper: “Conscientious refusal by physicians and pharmacists: who is obligated to do what, and why?”. (shrink)

I present an account of mental representation based upon the ‘SINBAD’ theory of the cerebral cortex. If the SINBAD theory is correct, then networks of pyramidal cells in the cerebral cortex are appropriately described as representing, or more specifically, as modelling the world. I propose that SINBAD representation reveals the nature of the kind of mental representation found in human and animal minds, since the cortex is heavily implicated in these kinds of minds. Finally, I show how SINBAD neurosemantics can (...) provide accounts of misrepresentation, equivocal representation, twin cases, and Frege cases. (shrink)

Non-skeptical robust realists about normativity, mathematics, or any other domain of non- causal truths are committed to a correlation between their beliefs and non- causal, mind-independent facts. Hartry Field and others have argued that if realists cannot explain this striking correlation, that is a strong reason to reject their theory. Some consider this argument, known as the Benacerraf–Field argument, as the strongest challenge to robust realism about mathematics, normativity, and even logic. In this article I offer two closely related accounts (...) for the type of explanation needed in order to address Field's challenge. I then argue that both accounts imply that the striking correlation to which robust realists are committed is explainable, thereby discharging Field's challenge. Finally, I respond to some objections and end with a few unresolved worries. (shrink)

Philosophers of physics have long debated whether the Past State of low entropy of our universe calls for explanation. What is meant by “calls for explanation”? In this article we analyze this notion, distinguishing between several possible meanings that may be attached to it. Taking the debate around the Past State as a case study, we show how our analysis of what “calling for explanation” might mean can contribute to clarifying the debate and perhaps to settling it, thus demonstrating the (...) fruitfulness of this analysis. Applying our analysis, we show that two main opponents in this debate, Huw Price and Craig Callender, are, for the most part, talking past each other rather than disagreeing, as they employ different notions of “calling for explanation”. We then proceed to show how answering the different questions that arise out of the different meanings of “calling for explanation” can result in clarifying the problems at hand and thus, hopefully, to solving them.

Many philosophers believe that when a theory is committed to an apparently unexplainable massive correlation, that fact counts significantly against the theory. Philosophical theories that imply that we have knowledge of non-causal mind-independent facts are especially prone to this objection. Prominent examples of such theories are mathematical Platonism, robust normative realism and modal realism. It is sometimes thought that theists can easily respond to this sort of challenge and that theism therefore has an epistemic advantage over atheism. In this paper, (...) I will argue that, contrary to widespread thought, some versions of theism only push the challenge one step further and thus are in no better position than atheism. (shrink)

Richard Nisbett and Dov Cohen’s (1996) influential account of “cultures of honor” speculates that honor norms are a socially-adaptive deterrence strategy. This theory has been appealed to by multiple empirically-minded philosophers, and plays an important role in John Doris and Alexandra Plakias’ (2008) antirealist argument from disagreement. In this essay, I raise four objections to the Nisbett-Cohen deterrence thesis, and offer another theory of honor in its place that sees honor as an agonistic normative system regulating prestige competitions. Since my (...) account portrays honor norms as radically different from liberal ones, it actually strengthens Doris and Plakias’ case in some respects: cultures of honor are not merely superficially different from Western liberal ones. Nonetheless, the persistent appeal of honor’s principles, and their moral plausibility in certain contexts, suggests not antirealism, but pluralism—a reply on behalf of realism that itself has considerable empirical support.

[Updated 2/23/21: complete chapter scan] In this chapter I sketch a rightist approach to monumentary policy in a diverse polity beleaguered by old ethnic grievances. I begin by noting the importance of tribalism, memorialization, and social trust. I then suggest a policy which 1) gradually narrows the gap between peoples in the heritage landscape, 2) conserves all but the most offensive of the least beloved racist monuments, 3) avoids recrimination (i.e., “keeps it positive”) and eschews ideological commentary in new monuments (...) or revisions to old ones, 4) as much as politically feasible, recognizes only the offense of willing tribemates, and 5) responds to aesthetic and other “irrational” offenses more than to “objective” historical or philosophical critiques.

Several authors believe that there are certain facts that are striking and cry out for explanation—for instance, a coin that is tossed many times and lands in the alternating sequence HTHTHTHTHTHT…. According to this view, we have prima facie reason to believe that such facts are not the result of chance. I call this view the striking principle. Based on this principle, some have argued for far-reaching conclusions, such as that our universe was created by intelligent design, that there are (...) many universes other than the one we inhabit, and that there are no mathematical or normative facts. Appealing as the view may initially seem, I argue that we lack sufficient reason to accept it. (shrink)

There is an obvious, perhaps even trite, argument against getting married which deserves our attention. Reduced to a crude sketch, the argument is simply that, most of us view the prospect of being married in the absence of mutual love with something like horror or at least great antipathy; the mutual love between us and our spouse existing at the inception of our marriage may very well fail to persist; and hence when we marry we are putting ourselves in the (...) position of quite possibly ending up in a loveless marriage of the sort we acknowledge to be undesirable, and this is a mistake.

We argue that the growing prevalence of statistical machine learning in everyday decision making – from creditworthiness to police force allocation – effectively replaces many of our humdrum practical judgments and that this will eventually undermine our capacity for making such judgments. We lean on Aristotle’s famous account of how phronesis and moral virtues develop to make our case. If Aristotle is right that the habitual exercise of practical judgment allows us to incrementally hone virtues, and if AI saves us (...) time by taking over some of those practical judgments, or if its pattern recognition capacities are very good at learning that kind of behavior – we risk innovating ourselves out of moral competence with the introduction of AI.

Consider our attitude toward painful and pleasant experiences depending on when they occur. A striking but rarely discussed feature of our attitude which Derek Parfit has emphasized is that we strongly wish painful experiences to lie in our past and pleasant experiences to lie in our future. Our asymmetrical attitudes toward future and past pains and pleasures can be forcefully illustrated by means of a thought-experiment described by Parfit (1984, 165) which I will paraphrase as follows: You are in the (...) hospital to have an extremely painful but completely safe operation for which you can be given no anaesthetic. In order to ease recovery, you know that the hospital will give you drugs that cause you to forget your operation as soon as it is completed. You wake up, not remembering having gone to sleep, and ask the nurse if your operation has been completed. She tells you that there were two patients for this operation and she cannot remember which you are: either you already had your operation and it was the longest such operation ever performed, lasting ten hours, or else you are the other patient in which case your operation is imminent, but will last only one hour. 1. I wish to thank Sarah Broadie for comments on a version of this paper and Derek Parfit for conversations on this subject. (shrink)

This article discusses the aesthetic concept of boringness, of which there has been relatively little philosophical discussion, especially along its objective, nonpsychological dimensions. I begin by confronting skepticism about the validity of judgments about boringness and rebut suggestions to the effect that these judgments are inevitably compromised by mistakes or vices of the audience. The article then develops an account focused on certain kinds of reasonable expectations we form in a given aesthetic context. I go on to confront the question (...) of whether boringness is inevitable given the internal imperatives of works of art and illustrate the discussion with Richard Wagner's Ring cycle. Although I focus on art, I conclude by drawing some connections with the boring in everyday life. (shrink)

This paper is an application of the principles of individuality found in Guay and Pradeu to illuminate biological individuality in mushrooms. I begin with the distinction between logico-cognitive individuals and ontological individuals, and then I argue for genidentity plus material continuity, as a minimum conception of ontological individuality in biology. Of the many materially-continuous genidenticals found in fungi, only those with functional roles in biological theory, either evolutionary or physiological, warrant consideration. Given numerous ways that theory picks out materially-continuous genidenticals (...) in fungi, I argue for a pluralistic account of mushroom individuality. (shrink)

Millikan and Her Critics offers a unique critical discussion of Ruth Millikan's highly regarded, influential, and systematic contributions to philosophy of mind and language, philosophy of biology, epistemology, and metaphysics.

It is widely recognized that prioritizing health care resources by their relative cost-effectiveness can result in lower priority for the treatment of disabled persons than otherwise similar non-disabled persons. I distinguish six different ways in which this discrimination against the disabled can occur. I then spell out and evaluate the following moral objections to this discrimination, most of which capture an aspect of its unethical character: it implies that disabled persons' lives are of lesser value than those of non-disabled persons; (...) it constitutes “double jeopardy” or violates Frances Kamm's non-linkage principle; it conflicts with equality of opportunity; it conflicts with fairness, which requires ignoring (some/most) differential impacts of treatment; it wrongly gives lower priority to disabled persons for equally effective treatment; it conflicts with giving all persons an equal chance to reach their full potential; and, it is in conflict with giving priority to the worse off.

John is currently thinking that the sun is bright. Consider his occurrent belief or judgement that the sun is bright. Its content is that the sun is bright. This is a truth- evaluable content (which shall be our main concern) because it is capable of being true or false.

To give the correct answer to that question, and to explain why John’s judgement and other contentful mental (...) states have the contents they do in virtue of such facts, would be to naturalize mental content.

This chapter examines whether an individual’s being worse off than others should be a relevant consideration in the allocation of limited medical resources. It reviews arguments pressed by proponents of different theories of justice about whether being worse off than others makes special demands on health care resource prioritization. Even if there is good reason to restrict the concern for the worse off to those with worse health in the prioritization and allocation of health care resources, additional issues remain. One (...) is how to determine who has worse health, and whether the worse off are those with the worse overall health or those with the most serious medical condition now in need of treatment. Another issue is whether only individuals’ present health, or instead their lifetime health, including past and expected future health, is relevant. (shrink)

This article develops, illustrates, and defends a conception of immanent critique. Immanent critique is construed as a form of hermeneutical practice and second-order political and normative criticism. The common charge that immanent critique is a form of philosophical conventionalism necessarily committed to value relativism and to the rejection of transcultural and cosmopolitan norms is denied. But immanent critique insists that meaningful and potentially efficacious criticism must be connected to relevant criteria and understandings internal to the culture or social order at (...) which the criticism is directed. The complaint that this demand will likely limit political and moral criticism is also denied, and the ability of immanent critique to develop from convention unconventional thinking is defended and demonstrated.

This paper addresses two questions: first, when making decisions about what to do, does the mere fact that we will feel regretful or guilty or proud afterward give us reason to act? I argue that these emotions of self-assessment give us little or no reason to act. The second question concerns emotional valence--how desirable or undesirable our emotions are. What is it that determines the valence of an emotion like regret? I argue that the valence of emotions, and indeed of (...) feelings like pain more broadly, is a function of the sensations they involve. As I suggest, understanding the point about emotional valence helps us answer the first question about anticipated emotions. The paper concludes with a discussion of death-bed regrets, and of whether teenagers should listen to their annoying parents. (shrink)

Reductive, naturalistic psychosemantic theories do not have a good track record when it comes to accommodating the representation of kinds. In this paper, I will suggest a particular teleosemantic strategy to solve this problem, grounded in the neurocomputational details of the cerebral cortex. It is a strategy with some parallels to one that Ruth Millikan has suggested, but to which insufficient attention has been paid. This lack of attention is perhaps due to a lack of appreciation for the severity of (...) the problem, so I begin by explaining why the situation is indeed a dire one. One of the main tasks for a naturalistic psychosemantic theory is to describe how the extensions of mental representations are determined. (Such a theory may also attempt to account for other aspects of the “meaning” of mental representations, if there are any.) Some mental representations, e.g. the concept of water, denote kinds (I shall be assuming this is non-negotiable). How is this possible? Unfortunately, I haven’t the space to canvass all the theories out there and show that each one fails to accommodate the representation of kinds, but I will point out the major types of problems that arise for the kinds of theories that, judging by the literature, are considered viable contenders.1 In general, the theories either attempt and fail to account for the representation of kinds, or they fall back on something like an intention to refer to a kind – not exactly the most auspicious move for a reductive theory. There are a number of problems that prevent non-teleosemantic theories from explaining how it is possible to represent kinds. A concept of a kind K must.. (shrink)

Such a bewildering and contradictory welter of behaviors and traits are connoted by “honor” and its best equivalents in other languages that analyses of the concept have daunted philosophers, anthropologists, sociologists, political scientists, historians, and literary scholars for millennia. Is it an external good given — and revoked just as easily — by others? Or does “honor” name an inner good that’s absolutely in our control: our integrity, our very commitment to right conduct? Is honor a central moral virtue — (...) as when we might say that “all was lost, save our honor”? Or is it a good quality that’s not-quite “moral,” or indeed even an antiquated virtue hostile to true morality? Is the honorable man a heroic figure who protects the weak, or one who can be expected to bully the weak, as in the case of “honor killings”? Is honor aristocratic and inegalitarian, and thus a virtue that enables and ennobles what’s essentially oppression? Or is honor a signal virtue of fair-dealing, fair-fighting, and fair competition, as evidenced in sportsmanship? (shrink)

This article challenges the consensus that silences about mental disorders are there to be broken. While silence in mental disorders can be painful, even deadly, the consensus rests on an oversimplified understanding of silence. Drawing upon accounts from depression and bipolar memoirs, this article names and analyses some salient experiences of silence in mood disorders. It does so with two goals in mind. The first is to show that mood disorders may involve several different kinds of lived experiences of silence. (...) This is important because even though silence is considered a promising objective symptom of depression, little has been written about lived experiences of silence in disorders that involve depression. The second is to argue against the fetishisation of breaking silence and the concomitant understandings of silence as an externally imposed and inherently negative phenomenon. This is important because some silences are not experienced as external and are even felt to be valuable, meaning that efforts to break them may be counterproductive. (shrink)

This essay reconsiders Jean-Jacques Rousseau’s debt to Jean Bodin, on the basis of Daniel Lee’s recent revision of Bodin as a theorist of popular sovereignty. It argues that Rousseau took a key feature of his own theory of democratic sovereignty from Bodin—namely, the dual identity of political members as both citizens and subjects of the state. It further makes the case that this dual identity originates in medieval corporatist law, which Bodin was summarizing. Finally, it demonstrates the lasting impact of (...) corporatist law in eighteenth-century France, highlighting Rousseau’s direct borrowings from the corporatist language and logic of contemporary commercial societies. In this regard, the article revisits and updates Otto von Gierke’s classic argument about the origins of the state in corporatist thought. (shrink)

The concept of protosemiosis or semiosis at the lower levels of the living goes back to Giorgio Prodi, Thomas A. Sebeok and others. More recently, a typology of proto-signs was introduced by Sharov and Vehkavaara. Kull uses the term of vegetative semiosis, defined by iconicity, when referring to plants and lower organism semiosis. The criteria for the typology of proto-signs by Sharov and Vehkavaara are mostly based on two important presuppositions: agency and a lack of representation in low-level semiosis. We (...) would like to focus on an alternative approach to protosign classification. In particular, we aim to provide a sign-typological characteristic of proteins (in analogy to Maran’ s classification of environmental signs). Our approach is focused on representation, that is, we only consider the relation between a sign and its object. We are considering representation independently from the role of interpretant and interpretation (which is an epiphenomenon of agency). Two hypotheses are investigated and accordingly evaluated in this paper: (I) Proteins are indexical protosigns. (II) Proteins are iconic protosigns. The conclusion our argumentation leads to supports the hypothesis (II). (shrink)

Some influential interpreters of Dharmakīrti have suggested understanding his thought in terms of a ‘sliding scale of analysis.’ Here it is argued that this emphasis on Dharmakīrti's alternating philosophical perspectives, though helpful in important respects, obscures the close connection between the two views in play. Indeed, with respect to these perspectives as Dharmakīrti develops them, the epistemology is the same either way. Insofar as that is right, John Dunne's characterization of Dharmakīrti's Yogācāra as ‘epistemic idealism ’ may not, after all, (...) distinguish this perspective from Sautrāntika; indeed, epistemic idealism can be understood as just the view these positions share. Thus, what distinguishes the ‘Yogācāra’ section of Dharmakīrti's texts is simply his making explicit that epistemological commitments the Sautrāntika does hold are already compatible with idealism. Sautrāntika and Yogācāra thus differ only when one turns to the metaphysical arguments that additionally show that only such mental things as sense data could be real. (shrink)

Debates about political correctness often proceed as if proponents see nothing to fear in erecting norms that inhibit expression on the one side, and opponents see nothing but misguided efforts to silence political enemies on the other.1 Both views are mistaken. Political correctness, as I argue, is an important attempt to advance the legitimate interests of certain groups in the public sphere. However, this type of norm comes with costs that mustn’t be neglected–sometimes in the form of conflict with other (...) values we hold dear, but often by creating an internal schism that threatens us with collective irrationality. Political correctness thus sets up dilemmas I wish to set out (but not, alas, resolve). The cliché is that political correctness tramples on rights to free-speech, as if the potential loss were merely expressive; the real issue is that in filtering public discourse, political correctness may defeat our own substantive aims.

: Bioethics has focused principally on ethical issues arising in clinical medicine. When it has addressed justice or equity, it has focused on access to health care and on defending a general moral right to health care. This dual focus on establishing a right to health care and on health care rather than health has left bioethics largely silent on two issues of fundamental importance for a full account of justice and health. First, the focus on establishing a right to (...) health care has contributed to a failure to address difficult issues in developing ethical standards for equitably prioritizing limited resources in health care. Second, the focus on inequalities in access to health care has ignored the much greater impact of social determinants of health, in particular socioeconomic class and inequality, on health and health inequalities. Bioethics must broaden its agenda. (shrink)

Rationing is the allocation of a good under conditions of scarcity, which necessarily implies that some who want and could be benefitted by that good will not receive it. One reflection of our ambivalence towards health care rationing is reflected in our resistance to having it distributed in a market like most other goods—most Americans reject ability to pay as the basis for distributing health care. They do not view health care as just another commodity to be distributed by markets. (...) Despite this widespread view, we are the only developed country without some form of universal health insurance, and so for the 46 million Americans without health insurance their access to health care often does depend on their ability to pay for it. Rationing largely remains a topic that the public, their elected leaders, and many health care professionals prefer to avoid. Ever-growing costs of health care will increasingly force the practice and issue of health care resource prioritization and rationing into the open for public, professional, and political attention. This paper explores some of the features of those practices and issues that make them especially ethically and politically difficult. Those issues will not be easily resolved, but avoiding them will not avoid the need or reality of rationing, it will only mean that it will go on covertly and unexamined. That will lead neither to better or more legitimate prioritization and rationing decisions. (shrink)

The intense and extensive debate over human embryonic stem cell research has focused primarily on the moral status of the human embryo. Some commentators assign full moral status of normal adult human beings to the embryo from the moment of its conception. At the other extreme are those who believe that a human embryo has no significant moral status at the time it is used and destroyed in stem cell research. And in between are many intermediate positions that assign an (...) embryo some degree of moral status between none and full. This controversy and the respective positions, like the abortion controversy, is by now well understood, despite the lack of progress in resolving it. I have argued briefly elsewhere that early embryos do not have significant moral status, but I do not want to reenter that debate here. Instead, I want to focus on an issue that has had relatively little explicit and separate attention, but is likely to loom larger in light of the Obama administration’s partial lifting of the Bush administration’s restriction on the embryos that can be used in stem cell research that receives federal funding.

This paper presents a computational model that integrates a dynamically structured holographic memory system into the ACT-R cognitive architecture to explain how linguistic representations are encoded and accessed in memory. ACT-R currently serves as the most precise expression of the moment-by-moment working memory retrievals that support sentence comprehension. The ACT-R model of sentence comprehension is able to capture a range of linguistic phenomena, but there are cases where the model makes the wrong predictions, such as the over-prediction of retrieval interference (...) effects during sentence comprehension. Here, we investigate one such case involving the processing of sentences with negative polarity items and consider how a dynamically structured holographic memory system might provide a cognitively plausible and principled explanation of some previously unexplained effects. Specifically, we show that by replacing ACT-R's declarative memory with a dynamically structured memory, we can explain a wider range of behavioral data involving reading times and judgments of grammaticality. We show that our integrated model provides a better fit to human error rates and response latencies than the original ACT-R model. These results provide proof-of-concept for the unification of two independent computational cognitive frameworks. (shrink)
