The mesostriatal dopamine system is prominently implicated in model-free reinforcement learning, with fMRI BOLD signals in ventral striatum notably covarying with model-free prediction errors. However, latent learning and devaluation studies show that behavior also shows hallmarks of model-based planning, and the interaction between model-based and model-free values, prediction errors, and preferences is underexplored. We designed a multistep decision task in which model-based and model-free influences on human choice behavior could be distinguished. By showing that choices reflected both influences we could (...) then test the purity of the ventral striatal BOLD signal as a model-free report. Contrary to expectations, the signal reflected both model-free and model-based predictions in proportions matching those that best explained choice behavior. These results challenge the notion of a separate model-free learner and suggest a more integrated computational architecture for high-level human decision-making. (shrink)

Do epistemic requirements vary along with facts about what promotes agents' well-being? Epistemic instrumentalists say 'yes', and thereby earn a lot of contempt. This contempt is a mistake on two counts. First, it is incorrectly based: the reasons typically given for it are misguided. Second, it fails to distinguish between first- and second-order epistemic instrumentalism; and, it happens, only the former is contemptible. -/- In this book, Nathaniel P. Sharadin argues for rejecting epistemic instrumentalism as a first-order view not (...) because it suffers extensional failures, but because it suffers explanatory ones. By contrast, he argues that epistemic instrumentalism offers a natural, straightforward explanation of why being epistemically correct matters. What emerges is a second-order instrumentalist explanation for epistemic authority that is neutral between competing first-order epistemic theories. -/- Epistemic Instrumentalism Explained will be of interest to researchers and advanced students working in epistemology, ethics, and philosophy of mind.

The moral of Buridan's Ass is that it can sometimes be rational to perform one action rather than another even though one lacks stronger reason to do so. Yet it is also commonly believed that it cannot ever be rational to believe one proposition rather than another if one lacks stronger reason to do so. This asymmetry has been taken to indicate a deep difference between epistemic and practical rationality. According to the view articulated here, the asymmetry should instead be (...) explained by the difference between rational intentions and rational actions. Thus, it turns out, Buridan's Ass-style cases do not indicate an asymmetry between epistemic and practical rationality as such. (shrink)

Except in extraordinary circumstances, patients' clinical care should reflect their preferences. Incapacitated patients cannot report their preferences. This is a problem. Extant solutions to the problem are inadequate: surrogates are unreliable, and advance directives are uncommon. In response, some authors have suggested developing algorithmic "patient preference predictors" (PPPs) to inform care for incapacitated patients. In a recent paper, Earp et al. propose a new twist on PPPs. Earp et al. suggest we personalize PPPs using modern machine learning (ML) techniques. In (...) this paper, I argue that, contrary to Earp et al.'s claim, personalized patient preference predictors are neither technically feasible nor ethically desirable. (shrink)

Alan Moore and Dave Gibbons’ Watchmen may be the most acclaimed graphic novel of the twentieth century. This chapter examines how it explores two metaphysical questions: What is the nature of time? Does free will exist? Moore and Gibbons explore these questions together, illuminating connections between time and free will through connections between the graphic novel’s form and content. The chapter introduces three views of the nature of time: presentism, the view that only the present exists; growing-universe theory, the view (...) that only the present and past exist; and eternalism, the view that past, present, and future exist. Because of Moore and Gibbons’ distinct use of images and words within the visual structure and their depiction of a character who is simultaneously aware of past, present, and future events, the chapter deduces that the operative view in Watchmen is eternalism. After discussing three views of the existence of free will, the chapter then argues that eternalism entails that people could not have acted otherwise than they actually acted. Hence the operative view in Watchmen is either determinism, according to which no one has free will because no one could have done otherwise, or compatibilism, according to which people can have free will because having it merely requires having acted. The chapter concludes that the operative view is compatibilism. Finally it responds to the objection that compatibilism is mistaken. If no one could have done otherwise, then determinism must be true. (shrink)

Jokes are sometimes morally objectionable, and sometimes they are not. What’s the relationship between a joke’s being morally objectionable and its being funny? Philosophers’ answers to this question run the gamut. In this paper I present a new argument for the view that the negative moral value of a joke can affect its comedic value both positively and negatively.

Call the epistemological grounds on which we rationally should determine our ontological (or alethiological) commitments regarding an entity its arbiter of existence (or arbiter of truth). It is commonly thought that arbiters of existence and truth can be provided by our practices. This paper argues that such views have several implications: (1) the relation of arbiters to our metaphysical commitments consists in indispensability, (2) realist views about a kind of entity should take the kinds of practices providing that entity’s arbiters (...) to align with respect to their metaphysical dependencies, (3) if realists take a kind of practice to provide grounds on which to affirm the existence of a kind of entity, they should turn to those same grounds when seeking to provide an epistemology of the relevant domain.

Fictionalists about a kind of disputed entity aim to give a face-value interpretation of our discourse about those entities without affirming their existence. The fictionalist’s commitment to non-realism leaves open three options regarding their ontological position: they may deny the existence of the disputed entities (anti-realism), remain agnostic regarding their existence (agnosticism), or deny that there are ontological facts of the matter (ontological anti-realism). This paper outlines a method of adjudicating between these options and argues that fictionalists may be expected (...) to hold preferences between them. The typical arguments and motivations for fictionalism lead naturally to a practice-based metaontological framework under which our practices regarding a kind of disputed entity might inform our ontological beliefs about those entities. When that framework is applied to fictionalism, it is found that the usual motivations for fictionalism lead naturally, though not decisively, to ontological anti-realism. And, where there are reasons against ontological anti-realism, fictionalism leans more toward anti-realism than agnosticism. (shrink)

What, according to proponents of doxastic deontologism, is responsible belief? In this paper, we examine two proposals. Firstly, that responsible belief is blameless belief (a position we call DDB) and, secondly, that responsible belief is praiseworthy belief (a position we call DDP). We consider whether recent arguments in favor of DDP, mostly those recently offered by Brian Weatherson, stand up to scrutiny and argue that they do not. Given other considerations in favor of DDP, we conclude that the deontologist should (...) maintain that doxastic responsibility is a concept about freedom from appropriate blame. (shrink)

This article conducts a mixed-method content analysis of Chinese and American news media coverage of Google DeepMind’s Go playing computer program, AlphaGo. Drawing on humanistic approaches to artificial intelligence, combined with an empirically rigorous content analysis, it examines the differences and overlap in coverage by the Chinese and American press in their accounts of AlphaGo, and its historic match with Korea’s Lee Sedol in March, 2016. The event was not only followed intensely in China, but also made the front page (...) of The New York Times. This article finds that the Chinese press was more likely than the American press to frame AlphaGo as non-threatening, which the authors attribute to cultural differences and the two countries' different understandings of Go. In addition to quantitatively identifying similarities and differences in the framing of AlphaGo, this paper also investigates the underlying and evolving contestations over what constitutes the “human” and the “machine.” It concludes by discussing the implications of the study’s findings as well as outlining avenues for further research.

Yes, Roya, a 2016 graphic novel written by C. Spike Trotman and illustrated by Emilee Denich, depicts Roya, a woman of color who writes and illustrates a comic strip; Joe, a white man who gave up his career after meeting Roya, who now publishes under his name; and Wylie, a young white man starting in the profession. Roya completely dominates Joe’s career, making it hers. She also partly dominates Wylie’s, acting as his mentor. Roya dominates Joe and Wylie personally too. (...) She is their sexual dominant, and they are her submissives. Professionally and personally, moreover, Joe and Wylie each submit to Roya consensually. Further, though Roya both writes and illustrates her comic strip, often writer and illustrator differ. The former, creating the story, dominates the latter, illustrating the story after the fact – as Trotman and Denich themselves did consensually via a contract when creating their graphic novel. Hence Yes, Roya highlights domination and submission in comics creation and in sex. More than that, the graphic novel also presents both kinds of domination and submission as ethical. Because Aristotle, Kant, and Mill are the most influential ethicists in the Western tradition, this chapter investigates how each could accommodate such professional and personal dominant/submissive relationships in their philosophy.

The Morality First strategy for developing AI systems that can represent and respond to human values aims to first develop systems that can represent and respond to moral values. I argue that Morality First and other X-First views are unmotivated. Moreover, according to some widely accepted philosophical views about value, these strategies are positively distorting. The natural alternative, according to which no domain of value comes “first” introduces a new set of challenges and highlights an important but otherwise obscured problem (...) for e-AI developers.

Many philosophers think the distinctive function of deontic evaluation is to guide action. This idea is used in arguments for a range of substantive claims. In this paper, we entirely do one completely destructive thing and partly do one not entirely constructive thing. The first thing: we argue that there is an unrecognized gap between the claim that the function of deontic evaluation is to guide action and attempts to put that claim to use. We consider and reject four arguments (...) intended to bridge this gap. The interim conclusion is thus that arguments starting with the claim that the function of deontic evaluation is to guide action have a lacuna. The second thing: we consider a different tack for making arguments of this sort work. We sketch a methodology one could accept that would do the trick. Unfortunately, as we’ll explain, although this methodology would bridge the gap in arguments that put claims about the function of deontic evaluation to work, it would do so in a way that vitiates any interest we might have in such arguments. As an aside, we’ll also point out how epistemologists, who have recently become interested in the function of epistemic evaluation, appear to already recognize this fact. The conclusion is hence a dilemma: either arguments from deontic function to substance have a lacuna or such arguments lack teeth. (shrink)

BackgroundThe terminal illness of late-stage Alzheimer’s and related dementias is progressively cruel, burdensome, and can last years if caregivers assist oral feeding and hydrating. Options to avoid prolonged dying are limited since advanced dementia patients cannot qualify for Medical Aid in Dying. Physicians and judges can insist on clear and convincing evidence that the patient wants to die—which many advance directives cannot provide. Proxies/agents’ substituted judgment may not be concordant with patients’ requests. While advance directives can be patients’ last resort (...) to attain a peaceful and timely dying consistent with their lifelong values, success depends on their being effective and acceptable. A single flaw can provide opponents justification to refuse the directive’s requests to cease assisted feeding.AimThis article considers 24 common advance directive flaws in four categories. Process flaws focus on how patients express their end-of-life wishes. Content flaws reflect drafters’ selection of conditions and interventions, and how they are described. Inherent flaws can make advance directives unacceptable to authorities concerned about premature dying. Strategies are needed to compel physicians to write needed orders and to prevent third parties from sabotaging these orders after they are implemented. The article includes excerpts from “dementia-specific” directives or supplements that exemplify each flaw—mostly from the US and Europe. No directive critiqued here included an effective strategy to resolve this long-debated bioethical conflict: the past directive requests “Cease assisted feeding” but the incapacitated patient apparently expresses the desire to “Continue assisted feeding.” Some opponents to the controversial request, cease assisted feeding, use this conflict as a conceptual wedge to practice hard paternalism. This article proposes a protocol to prevent this conflict from emerging. These strategies may prevent authorities from requiring patients to fulfill authorities’ additional clinical criteria as a prerequisite to honor the requests in patients directives.ConclusionThis critique of flaws may serve as a guide to drafting and to selecting effective and acceptable advance directives for dementia. It also poses several bioethical and clinical questions to those in authority: Does your paternalistic refusal to honor patients’ wishes respect their self-determination? Protect vulnerable patients from harm? Force patients to endure prolonged suffering? Violate the principles of bioethics? Violate the very foundation of patient-centered care? (shrink)

In a recent series of lectures delivered at the Institute of Fine Arts and the Frick Collection, Michael Ann Holly highlighted a moment in the 1950s when, she argues, art history made a pivotal choice, opting to follow Erwin Panofsky’s iconographic system of interpretation, based in a neo-Kantian historical distance, rather than Hans-Georg Gadamer’s theory of immediacy of experience.1 The dichotomy between visual experience and contextualization that Holly implicitly posits in her lecture suggests a long-standing tension in the historiography of (...) art history. Holly’s argument that Gadamer is a forgotten founder figure for the discipline of art history is a compelling one, not only for art history but, as I... (shrink)

When world’s most famous taxidermist, Carl Akeley, died in 1926, many obituaries cited his consummate skill and innovative technique, often arguing that he had elevated taxidermy from a craft to an art. Such claims notwithstanding, taxidermy tends still to be considered as a craft. While scholars have studied the various ways in which taxidermy has been deployed within art practices – to critique gender, colonialism and concepts of mortality – late nineteenth- and early twentieth-century attempts to classify it as a (...) fine art failed. This critical and historical asymmetry frames the following article, which explores what it tells us about how art is conceived today. I argue that taxidermy ‘failed’ as a form of art not because its procedures were distasteful, nor because its practice lacked the skill and vision an art might require. Rather, taxidermy remains outside of art due to a confluence of historical shifts in art practice and theory in the late nineteenth century, particularly those associated with the rise of instant photography and the advent of the snapshot. In this context, the making and display of taxidermied specimens entailed tensions – between ideal and real, type and example, multiple and singular, index and object – that were and remain central to photography and art. But, unlike photography, around which art historians have developed a sophisticated discourse, taxidermy lacks a critical vocabulary. Importantly, I argue, the taxidermied animal’s status involves no author-function, thus throwing into question methods of production and display. And, in light of this, I delineate taxidermy’s ‘failure’ in order to elucidate some of the tacit exclusions enacted by art history, particularly with regard to works that simultaneously reveal and negate their own manufacture.

Shah, N. The Philosophical Quarterly, 56, 481–498 (2006) has defended evidentialism on the premise that only it (and not pragmatism) is consistent with both (a) the deliberative constraint on reasons and (b) the transparency feature of belief. I show, however, that the deliberative constraint on reasons is also problematic for evidentialism. I also suggest a way for pragmatism to be construed so as to make it consistent with both (a) and (b) and argue that a similar move is not available (...) to the evidentialist. Thus, far from settling the debate in favour of evidentialism, considerations concerning the deliberative constraint on reasons support pragmatism. (shrink)

Radical contextualists have observed that the content of what is said by the utterance of a sentence is shaped in far-reaching ways by the context of utterance. And they have argued that the ways in which the content of what is said is shaped by context cannot be explained by semantic theory. A striking number of the examples that radical contextualists use to support their view involve sentences containing color adjectives ("red", "green", etc.). In this paper, I show how the (...) most sophisticated analysis of color adjectives within the explanatory framework of compositional truth conditional semantics—recently developed by Kennedy and McNally (Synthese 174(1): 79-98 2010)—needs to be modified to handle the full range of contextual variation displayed by color adjectives.

That holobionts are units of selection squares poorly with the observation that microbes are often recruited from the environment, not passed down vertically from parent to offspring, as required for collective reproduction. The taxonomic makeup of a holobiont’s microbial community may vary over its lifetime and differ from that of conspecifics. In contrast, biochemical functions of the microbiota and contributions to host biology are more conserved, with taxonomically variable but functionally similar microbes recurring across generations and hosts. To save what (...) is of interest in holobiont thinking, we propose casting metabolic and developmental interaction patterns, rather than the taxa responsible for them, as units of selection. Such units need not directly reproduce or form parent-offspring lineages: their prior existence has created the conditions under which taxa with the genes necessary to carry out their steps have evolved in large numbers. These taxa or genes will reconstruct the original interaction patterns when favorable conditions occur. Interaction patterns will vary in ways that affect the likelihood of and circumstances under which such reconstruction occurs. Thus, they vary in fitness, and evolution by natural selection will occur at this level. It is on the persistence, reconstruction, and spread of such interaction patterns that students of holobiosis should concentrate, we suggest. This model also addresses other multi-species collectively beneficial interactions, such as biofilms or biogeochemical cycles maintaining all life. (shrink)

John Rawls’s 1980 Dewey Lectures are widely acknowledged to represent the locus classicus for contemporary discussions of moral constructivism. Nevertheless, few published works have engaged with the significant interpretive challenges one finds in these lectures, and those that have fail to offer a satisfactory reading of the view that Rawls presents there or the place the lectures occupy in the development of Rawls's thinking. Indeed, there is a surprising lack of consensus about how best to interpret the constructivism of these (...) lectures. In this paper, I argue that the constructivism presented in the Dewey Lectures is best understood as involving the view that moral truth is correspondence with procedurally-determined, stance-dependent facts. Employing Rawls’s discussion of rational intuitionism as a foil, I defend this reading against textual discrepancies from within the lectures, as well as those one finds across Rawls’s other works. In addition to settling interpretive disputes, I draw out the ways in which this understanding of Kantian constructivism fits within the broader comparative project in ‘moral theory’ that Rawls inherits from Sidgwick.

The fact that someone is generous is a reason to admire them. The fact that someone will pay you to admire them is also a reason to admire them.

The Wrong Kind of Reasons Problem is the problem of explaining the difference between the ‘right’ (...) and the ‘wrong’ kind of reasons wherever it appears. In this article I argue that two recent proposals for solving the Wrong Kind of Reasons Problem do not work. I then offer an alternative solution that provides a unified, systematic explanation of the difference between the two kinds of reasons. (shrink)

In several articles, Mumma has presented a formal diagrammatic system Eu meant to give an account of one way in which Euclid's use of diagrams in the Elements could be formalized.

Twentieth-century developments in logic and mathematics have led many people to view Euclid’s proofs as inherently informal, especially due to the use of diagrams in proofs. In _Euclid and His Twentieth-Century Rivals_, Nathaniel Miller discusses the history of diagrams in Euclidean Geometry, develops a formal system for working with them, and concludes that they can indeed be used rigorously. Miller also introduces a diagrammatic computer proof system, based on this formal system.

Epistemic instrumentalists face a puzzle. In brief, the puzzle is that if the reason there is to believe in accord with the evidence depends, as the instrumentalist says it does, on agents’ idiosyncratic interests, then there is no reason to expect that this reason is universal.

Faced with the failure of these strategies, I articulate (...) a heretofore neglected solution on behalf of instrumentalism. (shrink)

Using the Public Value Mapping framework, I address the values successes and failures of chemistry as compared to the emerging field of green chemistry, in which the promoters attempt to incorporate new and expanded values, such as health, safety, and environmental sustainability, to the processes of prioritizing and conducting chemistry research. I document how such values are becoming increasingly public. Moreover, analysis of the relations among the multiple values associated with green chemistry displays a greater internal coherence and logic than (...) for conventional chemistry. Although traditional chemistry research has successfully contributed to both economic and values gains, there have been public values failures due to imperfect values articulations, failure to take a longer-term view, and inertia within a system that places too much emphasis on science values. Green chemistry, if implemented effectively, has potential to remedy these failures. (shrink)

Francisco de Vitoria (c. 1485-1546) is well-known for his philosophical contributions to natural rights and international law. However, his extensive work on the conflict between civil authority and the authority of the Catholic Church has been largely neglected by political theorists and intellectual historians. While scholars have recently recognized the significant role played by natural law in the history of political secularism, they have focused almost exclusively on the “modern” natural law theories of Hobbes, Pufendorf, and Thomasius, as opposed to (...) the “scholastic” natural law of early modern Thomists like Vitoria. This essay undertakes an analysis of Vitoria’s use of natural law theory in his approach to civil-ecclesiastical conflict. Contrary to critiques from the “modern” natural lawyers, it argues that Vitoria’s idea of natural law spearheads a forceful defence of the autonomy of civil power from ecclesiastical power. Based on his sharp distinction between the natural and the supernatural spheres of human life, Vitoria argues for a “dualist” position in which civil and ecclesiastical powers are independent and equally binding on human consciences. The essay acknowledges that Vitoria’s dualism ultimately gives way to his endorsement of papal supremacy over all Christian princes. However, this papalist conclusion does not follow from Vitoria’s natural law theory but rather from an opposing political principle: the notion of the universal Christian commonwealth. (shrink)

Marks individually or in combination constitute images that represent objects. How do those images represent those objects? Marks vary in style, both between and within images. Images also vary in style. How do those styles relate to each other and to the objects that those images represent?

We (...) answer the second question with a perceptual theory of style derived from Paul Grice, differentiating physical style from image style, and representing conventionally from representing conversationally.

Anscombe famously said that there are some act types that can only be done intentionally. We defend this claim: some act types are essentially intentional.

Finally, building on Piñeros Glassock (2020) and Beddor & Pavese (2022), we explain how this makes trouble for the thesis (...) that if I am Ving intentionally, I know that I am Ving. (shrink)
