This chapter introduces the articles by Marie C. Swabey, Thelma Z. Lavine, Grace A. de Laguna and Dorothy Walsh on the objectivity of scientific knowledge. We will see Swabey placing herself outside the historicist traditions of (later) authors (e.g., Thomas Kuhn), and arguing that the rationality and objectivity of science are grounded in synthetic a priori justified logical principles. Lavine and de Laguna, by contrast, embrace socio-historical approaches to the study of science, thus anticipating later developments in (...) philosophy of science. Still, whereas Lavine embraces a relativist notion of objectivity, de Laguna argues that science, at least in some respects, actually is universally valid. Walsh, finally, like Swabey, believes in context-independent objectivity that is grounded in metaphysics, but like de Laguna and Lavine, contends that such objectivity is discipline-specific.

This book is the first volume featuring the work of American women philosophers in the first half of the twentieth century. It provides selected papers authored by Mary Whiton Calkins, Grace Andrus de Laguna, Grace Neal Dolson, Marjorie Glicksman Grene, Marjorie Silliman Harris, Thelma Zemo Lavine, Marie Collins Swabey, Ellen Bliss Talbot, Dorothy Walsh and Margaret Floy Washburn. The book also provides the historical and philosophical background to their work. The papers focus on the nature of philosophy, knowledge, (...) the philosophy of science, the mind-matter nexus, the nature of time, and the question of freedom and the individual. The material is suitable for scholars, researchers and advanced philosophy students interested in (history of) philosophy; theories of knowledge; philosophy of science; mind, and reality. (shrink)

This paper uses the tools of experimental philosophy to examine the nature of interpersonal normativity in collective action, focusing on cases of immoral collective action and collective action by friends. The results of our two studies, which expand on recent empirical interventions into longstanding debates in social ontology, demonstrate that according to our everyday judgments there are interpersonal obligations in cases of collective action, even when immoral, and that, while friendship elicits judgments of togetherness, it does not affect the norms (...) of collective action. We also situate these results in the philosophical literature and discuss their consequences for a “pluralism” about sociality. (shrink)

The debate regarding the nature of joint action has come to a stalemate due to a dependence on intuitional methods. Normativists, such as Margaret Gilbert, argue that action-relative normative relations are inherent in joint action, while non-normativists, such as Michael Bratman, claim that there are minimal cases of joint action without normative relations. In this work, we describe the first experimental examinations of these intuitions, and report the results of six studies that weigh in favor of the normativist paradigm. Philosophical (...) ramifications and further extensions of this work are then discussed. (shrink)

Guido Löhr's recent article makes several insightful and productive suggestions about how to proceed with the empirical study of collective action. However, their critique of the conclusions drawn in Gomez-Lavin & Rachar (2022) is undermined by some issues with the interpretation of the debate and paper. This discussion article clears up those issues, presents new findings from experiments developed in response to Löhr's critiques, reflects on the role of experimental research in the development and refinement of philosophical theories, and adds (...) to Löhr's suggestions about the path forward.

Working memory is a foundational construct of cognitive psychology, where it is thought to be a capacity that enables us to keep information in mind and to use that information to support goal directed behavior. Philosophers have recently employed working memory to explain central cognitive processes, from consciousness to reasoning. In this paper, I show that working memory cannot meet even a minimal account of natural kindhood, as the functions of maintenance and manipulation of information that tie working memory models (...) and theories together do not have a coherent or univocal realizer in the brain. As such, working memory cannot explain central cognition. Rather, I argue that working memory merely redescribes its target phenomenon, and in doing so it obfuscates relevant distinctions amongst the many ways that brains like ours retain and transform information in the service of cognition. While this project ultimately erodes the explanatory role that working memory has played in our understanding of cognition, it simultaneously prompts us to evaluate the function of natural kinds within cognitive science, and signals the need for a productive pessimism to frame our future study of cognitive categories.

Working memory is thought to be the psychological capacity that enables us to maintain or manipulate information no longer in our environment for goal-directed action. Recent work argues that working memory is not a so-called natural kind and in turn cannot explain the cognitive processes attributed to it. This paper first clarifies the scope of this earlier critique and argues for a pluralist account of working memory. Under this account, working memory is variously realized by many mechanisms that contribute to (...) the maintenance and manipulation of information across tasks. This view in effect updates one of the earliest pluralist formulations of working memory. Juxtaposing this view against deflationary descriptions allows us to delineate two gradients that help us chart various accounts of working memory and identify their respective theoretical commitments. In turn, we can isolate those accounts that fail to accord with the evidence supporting a pluralist view, and we can begin to rehabilitate working memory as a pluralist, and ultimately more informative, construct.

Few have given an extended treatment of the non-statistical sense of normality: a sense captured in sentences like “dogs have four legs,” or “hammers normally have metal heads,” or “it is normal for badgers to take dust baths.” The most direct extant treatment is Bernhard Nickel’s Between Logic and the World, where he claims that the normal or characteristic for a kind is what we can explain by appeal to the right sorts of explanations. Just which explanatory strategies can ground (...) normalities, though, is difficult to determine without inviting circularity into the account. After raising this and other worries for Nickel’s account, I develop my own account according to which normal features are those which are explained by the kind of thing involved. (shrink)

In their target article, Lynch, Parke, and O’Malley argue against the quick application of causal, interventionist explanatory frameworks to microbiomes and their purported role in many disparate states, from obesity to anxiety. I think the authors have undersold the force of their argument. A careful consideration of the scope of their claims, made easier by a parallel drawn from the history of explanation in neuroscience, yields a productive pessimism: that causal explanations likely operate at the wrong level of analysis for (...) dynamic, distributed, Quineian entities like the microbiome. That is, we shouldn’t expect causal explanations for microbiomes at all—and this includes the authors’ own “microbiome success story” of C. difficile. Neuroscience, with its own computationally challenging, dynamic entity—the brain—may provide lessons for how to approach something like predictive control over the microbiome. (shrink)

What do we owe each other when we act together? According to normativists about collective action, necessarily something and potentially quite a bit. They contend that collective action inherently involves a special normative status amongst participants, which may, for example, involve mutual obligations to receive the concurrence of the others before leaving. We build on recent empirical work whose results lend plausibility to a normativist account by further investigating the specific package of mutual obligations associated with collective action according to (...) our everyday understanding. However, our results cast doubt on a proposed obligation to seek the permission of co-actors before exiting a collective action, and suggest instead that this obligation is a function of explicit promising. We then discuss how our results pave the path for a new normativism, a theory that neither under- nor overshoots the target given by our common conception of the interpersonal obligations present in collective action.*.

Recent studies demonstrate a moral self effect: continuity in moral values is crucial to ascriptions of identity in and over time. Since Locke, personal identity has been referred to as a ‘forensic’ concept, meaning that it plays a role in attributions of moral responsibility. If moral values are crucial to identity over time, then perceived changes in a person’s set of values may reduce responsibility for past deeds. To test this, we examined the moral self effect in parole contexts. In (...) this empirical article, we conducted two experiments, in which participants were significantly more likely to grant parole to agents who underwent a moral change as opposed to mere behavioral change. We conclude by discussing possible objections and implications of these philosophical results for the Lockean view of personal identity. -/- . (shrink)

To what extent do aesthetic taste and our interest in the arts constitute who we are? In this paper, we present a series of empirical findings that suggest anAesthetic Self Effectsupporting the claim that our aesthetic engagements are a central component of our identity. Counterfactual changes in aesthetic preferences, for example, moving from liking classical music to liking pop, are perceived as altering us as a person. The Aesthetic Self Effect is as strong as the impact of moral changes, such (...) as altering political partisanship or religious orientation, and significantly stronger than for other categories of taste, such as food preferences (Study 1). Using a multidimensional scaling technique to map perceived aesthetic similarities among musical genres, we determined that aesthetic distances between genres correlate highly with the perceived difference in identity (Study 2). Further studies generalize the Aesthetic Self Effect beyond the musical domain: general changes in visual art preferences, for example from more traditional to abstract art, also elicited a strong Self Effect (Study 3). Exploring the breadth of this effect we also found anAnaesthetic Self Effect.That is, hypothetical changes from aesthetic indifference to caring about music, art, or beauty are judged to have a significant impact on identity. This effect on identity is stronger for aesthetic fields compared to leisure activities, such as hiking or playing video games (Study 4). Across our studies, the Anaesthetic Self Effect turns out to be stronger than the Aesthetic Self Effect. Taken together, we found evidence for a link between aesthetics and identity: we are aesthetic selves. When our tastes in music and the arts or our aesthetic interests change we take these to be transformative changes. (shrink)

This paper examines a parallel between Aristotle’s account of phantasia and contemporary psychological models of working memory, a capacity that enables the temporary maintenance and manipulation of information used in many behaviors. These two capacities, though developed within two distinct scientific paradigms, share a common strategy of psychological explanation, Aristotelian Faculty Psychology. This strategy individuates psychological components by their target-domains and functional roles. Working memory and phantasia result from an attempt to individuate the psychological components responsible for flexible thought and (...) are thus implicated in most of our robust cognitive processes, from reading comprehension to problem solving. We then present two novel objections which suggest that these capacities cannot explain our ability to engage in flexible thought. To escape the resultant impasse, we survey alternatives and argue that most promising strategies depend on identifying the behaviors attributed to intelligent thought and action. (shrink)

A Zoom discussion about racism and ableism in philosophy.

Categorization and memory for specific items are fundamental processes that allow us to apply knowledge to novel stimuli. This study directly compares categorization and memory using delay match to category (DMC) and delay match to sample (DMS) tasks. In DMC participants view and categorize a stimulus, maintain the category across a delay, and at the probe phase view another stimulus and indicate whether it is in the same category or not. In DMS, a standard item working memory task, participants encode (...) and maintain a specific individual item, and at probe decide if the stimulus is an exact match or not. Constrained Principal Components Analysis was used to identify and compare activity within neural networks associated with these tasks, and we relate these networks to those that have been identified with resting state-fMRI. We found that two frontoparietal networks of particular interest. The first network included regions associated with the dorsal attention network and frontoparietal salience network; this network showed patterns of activity consistent with a role in rapid orienting to and processing of complex stimuli. The second uniquely involved regions of the frontoparietal central executive network; this network responded more slowly following each stimulus and showed a pattern of activity consistent with a general role in role in decision-making across tasks. Additional components were identified that were associated with visual, somatomotor and default mode networks. (shrink)

As a slew of recent work in epistemology has brought out, there is a range of cases where there's a strong temptation to say that prudential and (especially) moral considerations affect what we ought to believe. There are two distinct models of how this can happen. On the first, “reasons pragmatist” model, the relevant prudential and moral considerations constitute distinctively practical reasons for (or against) belief. On the second, “pragmatic encroachment” model, the relevant prudential and moral considerations affect what one (...) is epistemically justified in believing. The pragmatic encroachment model appears to have several advantages over reasons pragmatism, and this has led many recent philosophers to endorse the former. However, in this paper we argue that a version of reasons pragmatism can be (at least largely) saved from these purported disadvantages once paired with an independently plausible permissivism about epistemically justified outright belief. This hybrid view—“permissivist pragmatism”—holds that when there is more than one epistemically permitted doxastic attitude, practical (including moral) considerations can determine which epistemically permitted doxastic attitude one all-things-considered ought to have. This view avoids both the problems faced by simple versions of reasons pragmatism, and those that distinctively attend pragmatic encroachment, while preserving the advantages of each view. (shrink)

Although doubt (Tvivl) and despair (Fortvivlelse) are widely recognized as two central and closely associated concepts in Kierkegaard’s authorship, their precise relationship remains opaque in the extant interpretive literature. To shed light on their relationship, this paper develops a novel interpretation of Kierkegaard’s understanding of the connection between despair and our agency over our beliefs, and its significance for Kierkegaard’s ethics of belief. First, I show that an important yet largely overlooked form of Kierkegaardian despair involves either failing to take (...) ethico-religious responsibility for one’s practical agency over one’s beliefs, or misusing one’s practical agency over one’s beliefs by refusing to recognize or comply with externally given ethico-religious norms governing belief. Second, I argue that Kierkegaard takes properly exercising one’s agency over one’s beliefs to matter because beliefs are partly constitutive of the theological virtues (faith, hope, and love) that Kierkegaard regards as the cure for despair.

Feminist philosophers have long emphasized the ways in which women’s oppression takes a variety of forms depending on complex combinations of factors. These include women’s objectification, dehumanization and unjust gendered divisions of labour caused in part by sexist ideologies regarding women’s social role. This paper argues that feminized artificial intelligence (feminized AI) poses new and important challenges to these perennial feminist philosophical issues. Despite the recent surge in theoretical and empirical attention paid to the ethics of AI in general, a (...) strikingly small portion of this work has considered the impact of feminized AI in particular. Our aim is thus to draw attention to the new and pressing ethical challenges posed by feminized AI. Doing so is crucial not just to understanding the impact of these increasingly ubiquitous technologies, but also to our understanding of longstanding feminist philosophical concerns and efforts to ameliorate them.

According to a traditional interpretation of Kierkegaard, he endorses a strong form of direct doxastic voluntarism on which we can, by brute force of will, make a “leap of faith” to believe propositions that we ourselves take to be improbable and absurd. Yet most leading Kierkegaard scholars now wholly reject this reading, instead interpreting Kierkegaard as holding that the will can affect what we believe only indirectly. This paper argues that Kierkegaard does in fact endorse a restricted, sophisticated, and plausible (...) version of direct doxastic voluntarism. On Kierkegaard’s view, when we take ourselves to be in an epistemically permissive situation, we have the ability to form outright beliefs (but not credences) at will in virtue of our ability to voluntarily 1) open or close inquiry and 2) determine our attitude towards epistemic risk.

Kierkegaard's pseudonym Johannes Climacus famously defines faith as a risky “venture” that requires “holding fast” to “objective uncertainty.” Yet puzzlingly, he emphasizes that faith requires resolute conviction and certainty. Moreover, Climacus claims that all beliefs about contingent propositions about the external world “exclude doubt” and “nullify uncertainty,” but also that uncertainty is “continually present” in these very same beliefs. This paper argues that these apparent contradictions can be resolved by interpreting Climacus as a belief‐credence dualist. That is, Climacus holds that (...) beliefs and credences (i.e., degrees of belief) are two irreducibly distinct types of mental states. Beliefs are resolutions that close inquiry, thereby excluding doubt and reflecting subjective certainty by disregarding the possibility of error. Credences, by contrast, reflect assessments of evidential probabilities, thereby encoding a recognition of “objective uncertainty” by acknowledging the possibility of error. In addition to solving a vexing interpretive puzzle and showing how Kierkegaard anticipates contemporary views about the nature of belief and credence, this paper demonstrates that Kierkegaard developed a sophisticated account of the nature of belief, doubt, and certainty that merits serious philosophical consideration.

The COVID-19 pandemic has had a significant impact on the education sector globally, with over one billion students being held out of school as a result of quarantine measures. In response, education systems had to quickly shift to online learning to ensure that students could continue their education. The sudden shift to online learning has resulted in educators having to adapt to the use of technology in education rapidly. The COVID-19 pandemic has highlighted the importance of digital literacy for educators (...) and the need for ongoing training in digital skills. The pandemic has served as an example of emerging, more creative methods of teaching methods, and technology use in education will continue to evolve. Hybrid learning will be critical to delivering realistic educational experiences, and teachers must adapt to become facilitators instead of teachers. The pandemic experience will affect educators’ attitudes towards integrating information and communication technology (ICT) in education, resulting in a rise in the proportion of people who have a favorable opinion of integrating ICT to education. Ongoing training in digital abilities is necessary to gain a viable education. This paper highlights the need for educators to embrace digital literacy and adapt to emerging technologies to provide a quality education in the post-vaccine world. (shrink)

This chapter aims to get away from the ‘psychological attitude’ approach framing current philosophical discussion of delusion. We ask not what kind of attitude a delusion is – a belief or an imagination? Something else? – as if it were already clear what the ‘content’ of a delusion could be. We aim instead to shift attention to the question of the ‘object’ of delusions. What is delusion of? What is the object of this form of thinking? This focus on a (...) delusion’s object, over its attitudinal nature, is partly motivated by a desire properly to connect delusory thought with ordinary forms of fantastical thinking that are ubiquitous in the experiences faced by reflective humans in everyday life. We aim at securing a continuity, in a way that much extant discussion of delusion fails to, between delusory thought with more ordinary forms of thinking present in, for example, fantastical or magical thinking. Exploring familiar expressions of such thinking, especially those involved in love and loss, enables us to bring out the way in which such expressions convey forms of affective self-consciousness – that have the subject and her relations as an object – that are not naturally taken as reports liable to investigation as true or false. This raises the question about what how to think about what someone is doing when they give expression to a delusion should we think of them as expressing an attitude towards a truth or false content, or may they be doing something rather different?

On the dominant contemporary accounts of how practical considerations affect what we ought to believe, practical considerations either encroach on epistemic rationality by affecting whether a belief is epistemically justified, or constitute distinctively practical reasons for belief which can only affect what we ought to believe by conflicting with epistemic rationality. This paper argues that Søren Kierkegaard offers a promising alternative view on which practical considerations can affect what we ought to believe without either encroaching on or (necessarily) conflicting with (...) epistemic rationality by determining which among the epistemically permitted outright doxastic attitudes one should all‐things‐considered adopt.

Debunking arguments—also known as etiological arguments, genealogical arguments, access problems, isolation objec- tions, and reliability challenges—arise in philosophical debates about a diverse range of topics, including causation, chance, color, consciousness, epistemic reasons, free will, grounding, laws of nature, logic, mathematics, modality, morality, natural kinds, ordinary objects, religion, and time. What unifies the arguments is the transition from a premise about what does or doesn't explain why we have certain mental states to a negative assessment of their epistemic status. I examine (...) the common, underlying structure of the arguments and the different strategies for motivating and resisting the premises of debunking arguments. (shrink)

According to the thesis of doxastic wronging, our beliefs can non-derivatively wrong others. A recent criticism of this view claims that proponents of the doxastic wronging thesis have no principled grounds for denying that credences can likewise non-derivatively wrong, so they must countenance pervasive conflicts between morality and epistemic rationality. This paper defends the thesis of doxastic wronging from this objection by arguing that belief bears distinctive relationships to inquiry and blame that can explain why beliefs, but not credences, can (...) non-derivatively wrong. First, forming a belief (but not updating one’s credence) closes inquiry, and suspending judgment (but not updating one’s credence) opens inquiry. Consequently, beliefs can distinctively wrong others by prematurely closing inquiry or inappropriately opening inquiry. Second, beliefs (but not credences) can constitute blame. Unfittingly blaming someone can wrong them, and hence beliefs which constitute unfitting blame can distinctively wrong. In addition to defending the claim that only beliefs can non-derivatively wrong, this paper gestures towards an ethics of belief which attends to the relationship between belief and attitudes such as inquiry, faith, trust, and blame.

A widely shared intuition says moral statements like “Aborting at 150 days is permissible” seem vague. But what is the nature of such vagueness? This article proposes a novel, shifty semantic account of moral vagueness which argues: Moral vagueness is essentially a semantic phenomenon existing in our imperfect (moral) language; the referents of vague moral terms may shift under the right circumstance; our usage of vague moral terms may contribute to such shifts, but so may some factors beyond our control. (...) After the account is fleshed out, some distinctions will be drawn to differentiate it from other accounts of moral vagueness, and more importantly, efforts will be made to reconcile this account and moral realism. In conclusion, my account is by far the first (minimal) moral realism-friendly shifty semantic account of moral vagueness that successfully explains our intuitions about vague moral statements.

Ideal theory in social and political philosophy generally works to hide philosophical theories’ complicity in sustaining the structural violence and maintenance of white supremacy that are foundational to settler colonial societies.

Précis for a book symposium, with contributions from Meg Wallace, Louis deRosset, and Chris Tillman and Joshua Spencer.

Until fairly recently in the storied history of epistemology, it was believed, widely and almost uncontestedly, that the architecture of human knowledge was such that our beliefs rested on an ultimate, self-justifying bedrock of truth. But with the rise of the modern age via the Enlightenment, there arose in tandem certain thinkers, most notably René Descarte, who began to object that this foundation is simultaneously far smaller and far stronger than it was originally thought to be. Thus, according to this (...) new view, the foundation for human knowledge doesn’t turn out to support very much, but what it does support, it supports all but invincibly. Descartes’ system provoked a number of detractors who, instead of returning to the old view, began to question not only whether any such foundation existed at all, but whether one was even necessary. Their project, instead, was to dispense with the idea of a justifying foundation altogether, formulating in its place a system in which the only thing needed to justify a belief were other beliefs. As we will see, this move has proven calamitous to their pursuit of truth and clarity. In this essay, I intend to chart a course between Descartes and his detractors, addressing a few shortcomings of each, while aiming for something like that old foundational understanding of human knowledge.

Reviewed Work: The Leader's Two Bodies: Slavoj Žižek's Postmodern Political Theology by Claudia Breger.

Nihilism is the thesis that no composite objects exist. Some ontologists have advocated abandoning nihilism in favor of deep nihilism, the thesis that composites do not existO, where to existO is to be in the domain of the most fundamental quantifier. By shifting from an existential to an existentialO thesis, the deep nihilist seems to secure all the benefits of a composite-free ontology without running afoul of ordinary belief in the existence of composites. I argue that, while there are well-known (...) reasons for accepting nihilism, there appears to be no reason at all to accept deep nihilism. In particular, deep nihilism draws no support either from the usual arguments for nihilism or from considerations of parsimony. (shrink)

Moral debunking arguments are meant to show that, by realist lights, moral beliefs are not explained by moral facts, which in turn is meant to show that they lack some significant counterfactual connection to the moral facts (e.g., safety, sensitivity, reliability). The dominant, “minimalist” response to the arguments—sometimes defended under the heading of “third-factors” or “pre-established harmonies”—involves affirming that moral beliefs enjoy the relevant counterfactual connection while granting that these beliefs are not explained by the moral facts. We show that (...) the minimalist gambit rests on a controversial thesis about epistemic priority: that explanatory concessions derive their epistemic import from what they reveal about counterfactual connections. We then challenge this epistemic priority thesis, which undermines the minimalist response to debunking arguments (in ethics and elsewhere). (shrink)

Our aim here is to explore the prospects of a relativist response to moral debunking arguments. We begin by clarifying the relativist thesis under consideration, and we explain why relativists seem well-positioned to resist the arguments in a way that avoids the drawbacks of existing responses.

At bottom, the relativist response is no less question-begging than standard realist responses, and – when we turn our attention to the strongest formulation of the debunking argument (...) – the virtues of relativism turn out to be vices.

Background: There is no doubt that strawberry diseases are one of the most important reasons that led to the destruction of strawberry plants and their crops. This leads to obvious damage to these plants and they become inedible. Discovering these diseases after a good step for proper and correct treatment. Determining the treatment with high accuracy depends on the method used in the diagnosis. Correctly, expert systems can greatly help in avoiding damage to these plants. The expert system correctly diagnoses (...) strawberry disease to make it easier for farmers to find the right treatment based on the appropriate diagnosis. Objectives: The main goal of this expert system is to get the appropriate diagnosis of disease and the correct treatment. Methods: In this paper the design of the proposed Expert System which was produced to help Farmers and students interested in agriculture strawberry in diagnosing many of the strawberry diseases such as: Leaf Spots, Grey Mold, Red Stele/Red Core, Wilt, Powdery Mildew, Alternaria Spot, Black Root Rot, Anthracnose (black spot), and Angular Leaf Spot. The proposed expert system presents an overview about strawberry diseases are given, the cause of diseases are outlined and the treatment of disease whenever possible is given out. CLIPS language was used for designing and implementing the proposed expert system. Results: The proposed strawberry diseases diagnosis expert system was evaluated by Farmers and they were satisfied with its performance. Conclusions: The Proposed expert system is very useful for Farmers with strawberry problem and students interested in agriculture strawberry. (shrink)

Sometimes, learning about the origins of a belief can make it irrational to continue to hold that belief—a phenomenon we call ‘genealogical defeat’. According to explanationist accounts, genealogical defeat occurs when one learns that there is no appropriate explanatory connection between one’s belief and the truth. Flatfooted versions of explanationism have been widely and rightly rejected on the grounds that they would disallow beliefs about the future and other inductively-formed beliefs. After motivating the need for some explanationist account, we raise (...) some problems for recent versions of explanationism. Learning from their failures, we then produce and defend a more resilient explanationism. (shrink)

Rose and Schaffer (forthcoming) argue that teleological thinking has a substantial influence on folk intuitions about composition. They take this to show (i) that we should not rely on folk intuitions about composition and (ii) that we therefore should not reject theories of composition on the basis of intuitions about composition. We cast doubt on the teleological interpretation of folk judgments about composition; we show how their debunking argument can be resisted, even on the assumption that folk intuitions have a (...) teleological source; and we argue that, even if folk intuitions about composition carry no weight, theories of composition can still be rejected on the basis of the intuitions of metaphysicians.

Words, languages, symphonies, fictional characters, games, and recipes are plausibly abstract artifacts— entities that have no spatial location and that are deliberately brought into existence as a result of creative acts. Many accept that composition is unrestricted: for every plurality of material objects, there is a material object that is the sum of those objects. These two views may seem entirely unrelated. I will argue that the most influential argument against restricted composition—the vagueness argument—doubles as an argument that there can (...) be no abstract artifacts. There is no way to resist the vagueness argument against abstract artifacts that does not also undermine the vagueness argument against restricted composition. (shrink)

Virtually everyone agrees that, even after having presented the arguments for their positions, proponents of revisionary philosophical theories are required to provide some sort of account of the conflict between their theories and what the folk believe. I examine various strategies for answering the challenge from folk belief. The examination proceeds as a case study, whose focus is eliminativism about ordinary material objects. I critically assess eliminativist attempts to explain folk belief by appeal to paraphrase, experience, and intuition.

A presentation of the Lewis-Sider argument from vagueness for unrestricted composition and possible responses.

Particularists in material-object metaphysics hold that our intuitive judgments about which kinds of things there are and are not are largely correct. One common argument against particularism is the argument from arbitrariness, which turns on the claim that there is no ontologically significant difference between certain of the familiar kinds that we intuitively judge to exist (snowballs, islands, statues, solar systems) and certain of the strange kinds that we intuitively judge not to exist (snowdiscalls, incars, gollyswoggles, the fusion of the (...) my nose and the Eiffel Tower). Particularists frequently respond by conceding that there is no ontologically significant difference and embracing some sort of deflationary metaontology (relativism, constructivism, quantifier variance). I show -- by identifying ontologically significant differences -- that the argument can be resisted without retreating to any sort of deflationary metaontology. (shrink)

Evolutionary debunking arguments abound, but it is widely assumed that they do not arise for our perceptual beliefs about midsized objects, insofar as the adaptive value of our object beliefs cannot be explained without reference to the objects themselves. I argue that this is a mistake. Just as with moral beliefs, the adaptive value of our object beliefs can be explained without assuming that the beliefs are accurate. I then explore the prospects for other sorts of vindications of our object (...) beliefs—which involve “bootstrapping” from our experiences as of midsized objects—and I defend bootstrapping maneuvers against a variety of objections. Finally, I argue for an explanatory constraint on legitimate bootstrapping and show how some attempts to respond to debunking arguments run afoul of the constraint. (shrink)

You see a cherry and you experience it as red. A textbook explanation for why you have this sort of experience is going to cite such things as the cherry’s chemical surface properties and the distinctive mixture wavelengths of light it is disposed to reflect. What does not show up in this explanation is the redness of the cherry. Many allege that the availability of color-free explanations of color experience somehow calls into question our beliefs about the colors of objects (...) around us. We explore how such explanations are supposed to undermine color beliefs, and in particular whether evolutionary considerations have any special role to play. (shrink)

I provide a theory of the metaphysical foundations of identity: an account what grounds facts of the form a=b. In particular, I defend the claim that indiscernibility grounds identity.

The theory I defend is immune to this circularity.

When some objects are the parts of another object, they compose that object and that object is composite. This article is intended as an introduction to the central questions about composition and a highly selective overview of various answers to those questions. In §1, we review some formal features of parthood that are important for understanding the nature of composition. In §2, we consider some answers to the question: which pluralities of objects together compose something? As we will see, the (...) dominant answers are all of them and none of them. In §§3-4, we examine one of the main arguments that has driven philosophers to these extreme answers: the argument from vagueness. In §5, we turn to the question of whether composition is unique: is it sometimes the case that some things compose more than one thing? Finally, in §6, we turn from the question of which composites exist to the question of which composites exist fundamentally. (shrink)

There is a widespread, popular view—and one I basically endorse—that Nietzsche is, in one sense of the word, a nihilist. As Arthur Danto put it some time ago, according to Nietzsche, “there is nothing in [the world] which might sensibly be supposed to have value.” As interpreters of Nietzsche, though, we cannot simply stop here. Nietzsche's higher men, Übermenschen, “genuine philosophers”, free spirits—the types Nietzsche wants to bring forth from the human, all-too-human herds he sees around him with the fish (...) hooks, as he says, of his books—seem to engage in what looks like valuing. These free spirits are supposed to revalue the old values—revaluing, as is clear from the texts, is not simply to remove the old values from circulation (Nietzsche uses “umwerten” and not “entwerten”)—and they are supposed to create new values. And, of course, Nietzsche himself, free spirit that he is, takes on the task of revaluing all values and seems to assert many a strident evaluation. So we need to say more here. What are Nietzsche and his free spirits up to when they engage in what looks, for all the world, like a practice of valuing? What is the practice of valuing Nietzsche is recommending for his free spirits? I argue for two claims: (i) First, we end up facing an interpretive puzzle when we attempt to explain how Nietzsche's free spirits are supposed to engage in a practice of valuing. (ii) Second, we can solve the interpretive puzzle by taking Nietzsche's free spirits to be engaged in a fictionalist simulacrum of valuing. (shrink)

This article discusses how a wide range of apparently conflicting metaethical theories have been ascribed to Nietzsche. It reviews the major kinds of contemporary metaethical theories and the initial textual evidence for ascribing some version of each kind to Nietzsche. It then considers the objections to such ascriptions as well as arguments in favor of claims of the relative plausibility of ascribing one metaethical interpretation to Nietzsche over another. The article concludes with a serious consideration of the view that perhaps (...) Nietzsche simply does not have a considered metaethical stance. (shrink)
