It is illegitimate to read any ontology about "race" off of biological theory or data. Indeed, the technical meaning of "genetic variation" is fluid, and there is no single theoretical agreed-upon criterion for defining and distinguishing populations (or groups or clusters) given a particular set of genetic variation data. Thus, by analyzing three formal senses of "genetic variation"—diversity, differentiation, and heterozygosity—we argue that the use of biological theory for making epistemic claims about "race" can only seem plausible when it relies (...) on the user’s own assumptions about race; the move from biological measures to claims about “race” inevitably amounts to a pernicious reification. We also excavate assumptions in the history of the technical discourse over the concept of "race" (e.g., Livingstone's and Dobzhansky's 1962 exchange, Edwards' 2003 response to Lewontin 1972, as well as contemporary discussions of cladistic "race", and "races" as clusters). We show that claims about the existence (or non-existence) of "race" are underdetermined by biological facts, methods, and theories. Biological theory does not force the concept of "race" upon us; our social discourse, social ontology, and social expectations do. We become prisoners of our abstractions at our own hands, and at our own expense. (shrink)

The aim of my paper is to describe and evaluate different conceptions of holism in Ludwig Wittgenstein’s Tractatus Logico-Philosophicus. I distinguish three readings of holistic elements in this work: i) Minimal Holism (E. Anscombe, M. Black, D. Pears); ii) Moderate Holism (J. Conant, C. Diamond, G. Ryle); and iii) Radical Holism (G. Bar-Elli, M. Kremer, P. Livingston). The conclusion is that the most viable option is Moderate Holism since it embraces the logico-syntactical notion of use, rejects an anachronistic interpretation (...) of Tractatarian ontology and allows us to see that the holistic elements are complementary to the initial atomism of the work. Moreover, I point to the consequences of the topic for the overall reading of Wittgenstein’s early and late work. (shrink)

Beginning with the prevalent idea that creativity is the ability to make or do things having valuable novelty, the paper explores a variety of axiological and novelty conditions and defends an instrumental success condition. I discuss Robert K. Merton's distinction between 'originality' and 'priority', and Margaret Boden's similar distinction between historical and psychological creativity, as well as Thomas Reid's and Bruce Vermazen's remarks on relations between novelty and value.

Some contemporary discussion about the explanation of consciousness substantially recapitulates a decisive debate about reference, knowledge and justification from an earlier stage of the analytic tradition. In particular, I argue that proponents of a recently popular strategy for accounting for an explanatory gap between physical and phenomenal facts – the so-called “phenomenal concept strategy” – face a problem that was originally fiercely debated by Schlick, Carnap, and Neurath. The question that is common to both the older and the contemporary discussion (...) is that of how the presence or presentation of phenomenal experiences can play a role in justifying beliefs or judgments about them. This problem is, moreover, the same as what was classically discussed as the problem of acquaintance. Interestingly, both physicalist and non-physicalist proponents of the phenomenal concept strategy today face this problem. I consider briefly some recent attempts to solve it and conclude that, although it is prima facie very plausible that acquaintance exists, we have, as yet, no good account of it. (shrink)

This project is an investigation into the prospects for an antirealist theory of essence. Essentialism is the claim that at least some things have some of their properties essentially. Essentialist discourse includes claims such as “Socrates is essentially human”, and “Socrates is accidentally bearded”. Historically, there are two ways of interpreting essentialist discourse. I call these positions ‘modal essentialism’ and ‘neo-Aristotelian essentialism’. According to modal essentialism, for Socrates to be essentially human is for it to be necessary that he be (...) a human if he exists, and for Socrates to accidentally have a beard is for it to be contingent that Socrates has a beard if he exists. According to neo-Aristotelian essentialism, objects have definitions in something like the way words do. For Socrates to be essentially human but accidentally bearded is for it to be part of the definition of Socrates that he is human, but not part of that definition that he is bearded. I argue that both are susceptible to antirealist interpretation. This thesis sets about showing that this is the case. In Chapters One and Two I investigate neo-conventionalist theories of modality, in the hope of using such a position to develop an antirealist modal essentialism. In Chapter Three I discuss the debate between modal and neo-Aristotelian essentialism and conclude that it is by no means settled. In Chapter Four I develop an antirealist neo-Aristotelian essentialism based on the mechanism of one of the neo-conventionalist accounts of modality. In Chapter Five I argue that this account is in a better position to give an essentialist theory of necessity than its realist counterparts. I conclude that, regardless of whether one is a modal or neo-Aristotelian essentialist, antirealist essentialism is a viable theory of essence that is worthy of consideration in contemporary debate.

Infinity exists as a concept but has no existence in actuality. For infinity to have existence in actuality either time or space have to already be infinite. Unless something is already infinite, the only way to become infinite is by an 'infinity leap' in an infinitely small moment, and this is not possible. Neither does infinitely small have an existence since anything larger than zero is not infinitely small. Therefore infinity has no existence in actuality.

Defense of a psychological account of what it is for an artwork to be complete.

Response to Gover (2015) on Trogdon and Livingston (2015) on artwork completion.

This letter addresses the editorial decision to publish the article, “Research on group differences in intelligence: A defense of free inquiry” (Cofnas, 2020). Our letter points out several critical problems with Cofnas's article, which we believe should have either disqualified the manuscript upon submission or been addressed during the review process and resulted in substantial revisions.

In this essay, we consider the formal and ontological implications of one specific and intensely contested dialectical context from which Deleuze’s thinking about structural ideal genesis visibly arises. This is the formal/ontological dualism between the principles, ἀρχαί, of the One (ἕν) and the Indefinite/Unlimited Dyad (ἀόριστος δυάς), which is arguably the culminating achievement of the later Plato’s development of a mathematical dialectic.3 Following commentators including Lautman, Oskar Becker, and Kenneth M. Sayre, we argue that the duality of the One and (...) the Indefinite Dyad provides, in the later Plato, a unitary theoretical formalism accounting, by means of an iterated mixing without synthesis, for the structural origin and genesis of both supersensible Ideas and the sensible particulars which participate in them. As these commentators also argue, this duality furthermore provides a maximally general answer to the problem of temporal becoming that runs through Plato’s corpus: that of the relationship of the flux of sensory experiences to the fixity and order of what is thinkable in itself. Additionally, it provides a basis for understanding some of the famously puzzling claims about forms, numbers, and the principled genesis of both attributed to Plato by Aristotle in the Metaphysics, and plausibly underlies the late Plato’s deep considerations of the structural paradoxes of temporal change and becoming in the Parmenides, the Sophist, and the Philebus. After extracting this structure of duality and developing some of its formal, ontological, and metalogical features, we consider some of its specific implications for a thinking of time and ideality that follows Deleuze in a formally unitary genetic understanding of structural difference. These implications of Plato’s duality include not only those of the constitution of specific theoretical domains and problematics, but also implicate the reflexive problematic of the ideal determinants of the form of a unitary theory as such. We argue that the consequences of the underlying duality on the level of content are ultimately such as to raise, on the level of form, the broader reflexive problem of the basis for its own formal or meta-theoretical employment. We conclude by arguing for the decisive and substantive presence of a proper “Platonism” of the Idea in Deleuze, and weighing the potential for a substantive recuperation of Plato’s duality in the context of a dialectical affirmation of what Deleuze recognizes as the “only” ontological proposition that has ever been uttered. This is the proposition of the univocity of Being, whereby “being is said in the same sense, everywhere and always,” but is said (both problematically and decisively) of difference itself. (shrink)

Despite the lack of evidence for their effectiveness, the use of physical restraints for patients is widespread. The best ethical justification for restraining patients is that it prevents them from harming themselves. We argue that even if the empirical evidence supported their effectiveness in achieving this aim, their use would nevertheless be unethical, so long as well known exceptions to informed consent fail to apply. Specifically, we argue that ethically justifiable restraint use demands certain necessary and sufficient conditions. These conditions (...) are that the physician obtain informed consent for their application, that their application be medically appropriate, and that restraints be the least liberty-restricting way of achieving the intended benefit. It is a further question whether their application is ever medically appropriate, given the dearth of evidence for their effectiveness. (shrink)

As biological and biomedical research increasingly reference the environmental context of the biological entities under study, the need for formalisation and standardisation of environment descriptors is growing. The Environment Ontology (ENVO) is a community-led, open project which seeks to provide an ontology for specifying a wide range of environments relevant to multiple life science disciplines and, through an open participation model, to accommodate the terminological requirements of all those needing to annotate data using ontology classes. This paper summarises ENVO’s motivation, (...) content, structure, adoption, and governance approach. (shrink)

Metaphors for describing the introduction, impacts, and management of non-native species are numerous and often quite outspoken. Policy-makers have adopted increasingly disputed metaphorical terms from scientific discourse. We performed a critical analysis of the use of strong metaphors in reporting scientific findings to policy-makers. Our analysis shows that perceptions of harm, invasiveness or nativeness are dynamic and inevitably display multiple narratives in science, policy or management. Improving our awareness of multiple expert and stakeholder narratives that exist in the context of (...) non-native species management, as well as metaphorical alternatives, is critical. (shrink)

Wittgenstein’s concepts shed light on the phenomenon of schizophrenia in at least three different ways: with a view to empathy, scientific explanation, or philosophical clarification. I consider two different “positive” wittgensteinian accounts―Campbell’s idea that delusions involve a mechanism of which different framework propositions are parts, Sass’ proposal that the schizophrenic patient can be described as a solipsist, and a Rhodes’ and Gipp’s account, where epistemic aspects of schizophrenia are explained as failures in the ordinary background of certainties. I argue that (...) none of them amounts to empathic-phenomenological understanding, but they provide examples of how philosophical concepts can contribute to scientific explanation, and to philosophical clarification respectively.

In this chapter, we outline the interdisciplinary contributions that philosophy, psychology, and neuroscience have provided in the understanding of the self and identity, focusing on one specific line of burgeoning research: the importance of morality to perceptions of self and identity. Of course, this rather limited focus will exclude much of what psychologists and neuroscientists take to be important to the study of self and identity (that plethora of self-hyphenated terms seen in psychology and neuroscience: self-regulation, self-esteem, self-knowledge, self-concept, self-perception, (...) and more). We will likewise not engage with many canonical philosophical treatments of self and identity. But we will lay out a body of research that brings together classic themes in philosophy, psychology, and neuroscience to raise empirically tractable philosophical questions, and philosophically rigorous empirical questions about self and identity. More specifically, in section 4.2, we will review some recent research that has treated traditional philosophical questions about self and identity as empirical questions. Within this body of work, we will be primarily concerned with the finding that morality (more so than memory) is perceived to be at the core of self and identity. Then, in section 4.3, we raise and respond to a variety of questions and criticisms: first, about the operationalization of identity concepts in the empirical literature; second, about the generalizability of the moral self effect; third, about the direction of change; fourth, about connections with recent work in neuroscience; and fifth, about the target of evaluation. Finally, in section 4.4, we consider a variety of implications and applications of this work on the moral self. Throughout, we aim to highlight connections between classical themes in philosophy, psychology, and neuroscience, while also suggesting new directions for interdisciplinary collaboration. (shrink)

In this paper we propose a very general de nition of combination of logics by means of the concept of sheaves of logics. We first discuss some properties of this general definition and list some problems, as well as connections to related work. As applications of our abstract setting, we show that the notion of possible-translations semantics, introduced in previous papers by the first author, can be described in categorial terms. Possible-translations semantics constitute illustrative cases, since they provide a new (...) semantical account for abstract logical systems, particularly for many-valued and paraconsistent logics.

O presente trabalho visa apresentar a solução dada por Santo Agostinho ao problema do mal, aliado à aparente contraditoriedade entre a presciência de Deus e a liberdade humana. Para isto, será útil como bibliografia principal do filósofo sua obra De libero arbitrio, um livro em forma de diálogo onde o pensador esclarece suas posições acerca do livre-arbítrio e da presciência divina.

This collection brings together fourteen contributions by authors from around the globe. Each of the contributions engages with questions about how local and global bioethical issues are made to be comparable, in the hope of redressing basic needs and demands for justice. These works demonstrate the significant conceptual contributions that can be made through feminists' attention to debates in a range of interrelated fields, especially as they formulate appropriate responses to developments in medical technology, global economics, population shifts, and poverty.

Conceptualism is the view that at least some perceptual representation is conceptual. This paper considers a prominent recent argument against Conceptualism due to Ned Block. Block’s argument appeals to patterns of color representation in infants, alleging that infants exhibit categorical perception of color while failing to deploy concepts of color categories. Accordingly, the perceptual representation of color categories in infancy must be non-conceptual. This argument is distinctive insofar as it threatens not only the view that all perception is conceptual, but (...) also views that restrict the Conceptualist thesis to perceptual categorization. However, I contend that it fails at two stages. Block’s arguments for the perceptual representation of color categories in infancy, and against color concept deployment in infancy, are unpersuasive. Thus, Block has not vanquished Conceptualism. I draw out implications for debates about the perception-cognition border and for the question of whether explicit categorization occurs in perception.

In a reflective and richly entertaining piece from 1979, Doug Hofstadter playfully imagined a conversation between ‘Achilles’ and an anthill (the eponymous ‘Aunt Hillary’), in which he famously explored many ideas and themes related to cognition and consciousness. For Hofstadter, the anthill is able to carry on a conversation because the ants that compose it play roughly the same role that neurons play in human languaging; unfortunately, Hofstadter’s work is notably short on detail suggesting how this magic might be achieved1. (...) Conversely in this paper - finally reifying Hofstadter’s imagination - we demonstrate how populations of simple ant-like creatures can be organised to solve complex problems; problems that involve the use of forward planning and strategy. Specifically we will demonstrate that populations of such creatures can be configured to play a strategically strong - though tactically weak - game of HeX (a complex strategic game).We subsequently demonstrate how tactical play can be improved by introducing a form of forward planning instantiated via multiple populations of agents; a technique that can be compared to the dynamics of interacting populations of social insects via the concept of meta-population. In this way although, pace Hofstadter, we do not establish that a meta-population of ants could actually hold a conversation with Achilles, we do successfully introduce Aunt Hillary to the complex, seductive charms of HeX.

High blood pressure is an important component of pre-eclampsia. The underlying mechanism of development of hypertension in pre-eclampsia is complicated and still remains obscure. Several theories have been advanced including endothelial dysfunction, uteroplacental insufficiency leading to generalized vasoconstriction, increased cardiac output, and sympathetic hyperactivity. Increased blood flow and pressure are thought to lead to capillary dilatation, which damages end-organ sites, leading to hypertension, proteinuria and edema. Additional theories have been put forward based on epidemiological research, implicating immunological and genetic factors. (...) None of these theories have been substantiated. Based on a review of literature this paper postulates that the initiating event for the development of preeclampsia is intermittent hypoxia associated with irregular breathing during sleep, hypoapnea, apnea,inadequate respiratory excursions during the waking hours and inadequate cardiopulmonary synchronization (abnormal sympatho-vagal balance).

A pecuária brasileira tem destaque acentuado quanto a sua participação no produto interno Bruto nacional (PIB), entretanto, dentro da cadeia produtiva das proteínas de origem animal, a ovinocultura ainda se apresenta como uma atividade com pouca expressividade e tecnificação frente a outras espécies animais domésticas, desta forma seu fomento e próspero desenvolvimento é dependente de inúmeros fatores, sendo que destes o correto manejo reprodutivo de espécies , a escolha de raças autóctones ou do exterior com boa adaptabilidade para serem criadas (...) em regiões de clima tropical e subtropical encontrados no Brasil e a correta seleção quanto a características reprodutivas de matrizes e principalmente de jovens carneiros cujos quais se deseja utilizar como reprodutores em rebanhos que buscam a constante evolução produtiva se faz muito importante. Tal cenário traz à tona a importância da realização de estudos referentes a suplementação de elementos como vitaminas e microminerais, que embora não sejam os maiores constituintes das dietas ofertadas aos animais de interesse zootécnico, exercem grande influência não só no crescimento e desenvolvimento do tecido muscular como também podem estar positivamente correlacionados quanto aos aspectos reprodutivos . O presente trabalho objetivou a avaliação da qualidade seminal e morfometria testicular de carneiros púberes submetidos a suplementação injetável de minerais e vitaminas, sendo utilizados 30 reprodutores divididos em três grupos de dez animais cada, com delineamento dos grupos inteiramente casualizado. Ao primeiro grupo foi administrada suplementação vitamínica e mineral (Grupo VM), no segundo grupo houve apenas suplementação vitamínica (Grupo VIT) e no terceiro grupo a suplementação mineral (Grupo MIN). No presente trabalho buscou-se avaliar os efeitos da aplicação de complexo vitamínico e mineral sobre a qualidade do sêmen ovino, medidas morfométricas testiculares e alteração nas concentrações dos hormônios cortisol e testosterona. Palavras chave: elementos-traço, hormônios, nutracêutico, ovinos, sêmen -/- Brazilian livestock has a strong emphasis in terms of its participation in the Gross National Product (GDP), however, within the production chain of animal proteins, sheep farming still presents itself as an activity with little expressiveness and technology compared to other domestic animal species. in this way its promotion and development depends on the correct methods, which are the reproductive of sheep species, the choice of indigenous or foreign breeds with good adaptability to be created in tropical and subtropical regions found in Brazil and the correct selection of selected animals and selection of products that are very important for the demand for products of constant breeding. This scenario leads to the development of important studies for the supplementation of such vitamins and trace minerals, which, although not the largest components of diets, exert a great influence not only on the growth of muscle tissues but can also be positively correlated with their reproductive aspects. The present evaluation of seminal quality and testicular morphometric of pubertal animals includes an injectable supplement of vitamins and minerals, using 30 sires distributed in three groups of animals each, with a completely random design of the products. The first supplementary group was given the mineral supplement (VM Group) in the second group only vitamin supplementation (VM Group) and the mineral supplementation group (MIN Group).

Resumo: A crise na União Europeia e os programas de austeridade subsequentes fizeram emergir uma miríade de movimentos sociais, diversos na sua natureza e nos seus propósitos. O que se pretende aferir neste artigo é a relação e a conexão existentes entre o Estado, o poder económico, a sociedade civil e os movimentos sociais neste contexto específico de crise. Procuraremos, nesta breve abordagem, explanar alguns elementos de originalidade intrínsecos aos movimentos sociais hodiernos, patentes na sua forma de participação e organização, (...) assim como aplicar estas questões teóricas relevantes ao contexto português. A parte empírica, dada a escassez de estudos de caso existentes, será apoiada no último inquérito do European Social Survey, de 2012. Analisando um conjunto de perguntas aí explícitas, podemos compreender, de forma indirecta, algumas das dinâmicas que caracterizam estes movimentos. Abstract: The crisis in the European Union and the subsequent austerity programs have unleashed a myriad of social movements, diverse in its nature and purpose. The purpose of this paper is to assess the relationship and connection between the State, economic power, civil society and social movements in this specific context of crisis. We will try, in this brief approach, to explain some elements of originality intrinsic to modern social movements, evident in their form of participation and organization, as well as to apply these theoretical questions relevant to the Portuguese context. The empirical part, given the paucity of existing case studies, will be supported in the last survey of the European Social Survey of 2012. By analyzing a set of questions explicit there, we can, indirectly, understand some of the dynamics that characterize these movements. (shrink)

De uma perspectiva comportamentalista radical, o eu é um repertório verbal complexo, que, como tal, tem uma gênese social. O reconhecimento da origem social do “eu” abre caminho para uma análise política, incluindo uma discussão do pa- pel das relações de poder na constituição do eu. Entretanto, uma concepção radicalmente social do “eu”, como a proposta pelo comportamentalismo, suscita um problema político: se o eu é integralmente produto do ambiente social, de onde viria uma eventual “vontade” de romper com esse (...) sistema? Parece que para reconhecer a possibilidade de ação política transformadora seria preciso preservar uma noção descontextualizada de “eu”. Considerando essa dificuldade, o objetivo deste artigo é propor uma interpretação política da constituição do “eu” no âmbito do comportamentalismo radical, mantendo no horizonte a possibilidade de uma ação política transformadora. Para tanto, destacamos como “eus” oprimidos são tornados submissos, mas também como de certas contingências podem emergir “eus” subversivos, que se opõem a um sistema social opressivo. Esse “eu” subversivo é caracterizado por um repertório de autoconhecimento mais amplo, que inclui a discriminação do papel das relações de poder e do controle promovido por instituições. Concluímos, com isso, que um “eu” socialmente constituído pode ser politicamente ativo. (shrink)

Marr’s seminal distinction between computational, algorithmic, and implementational levels of analysis has inspired research in cognitive science for more than 30 years. According to a widely-used paradigm, the modelling of cognitive processes should mainly operate on the computational level and be targeted at the idealised competence, rather than the actual performance of cognisers in a specific domain. In this paper, we explore how this paradigm can be adopted and revised to understand mathematical problem solving. The computational-level approach applies methods from (...) computational complexity theory and focuses on optimal strategies for completing cognitive tasks. However, human cognitive capacities in mathematical problem solving are essentially characterised by processes that are computationally sub-optimal, because they initially add to the computational complexity of the solutions. Yet, these solutions can be optimal for human cognisers given the acquisition and enactment of mathematical practices. Here we present diagrams and the spatial manipulation of symbols as two examples of problem solving strategies that can be computationally sub-optimal but humanly optimal. These aspects need to be taken into account when analysing competence in mathematical problem solving. Empirically informed considerations on enculturation can help identify, explore, and model the cognitive processes involved in problem solving tasks. The enculturation account of mathematical problem solving strongly suggests that computational-level analyses need to be complemented by considerations on the algorithmic and implementational levels. The emerging research strategy can help develop algorithms that model what we call enculturated cognitive optimality in an empirically plausible and ecologically valid way. (shrink)

In this article, I examine the moral dimensions of gender affirmation. I argue that the moral value of gender affirmation is rooted in what Iris Murdoch called loving attention. Loving attention is central to the moral value of gender affirmation because such affirmation is otherwise too fragile or insincere to have such value. Moral reasons to engage in acts that gender affirm derive from the commitment to give and express loving attention to trans people as a way of challenging their (...) marginalization. In the latter part of the paper, I will discuss how my arguments bear on recent arguments by Robin Dembroff and Daniel Wodak (2018) on the use of gender-neutral language. They argue that we have a duty not to use gender-specific pronouns for anyone. Their conclusion turns, in part, on a rejection of gender affirmation as a moral duty. The value of gender affirmation, rooted in our moral perception of trans people, should make us skeptical of this conclusion, in favor of a more nuanced and pluralistic approach to the ethics of gendering.

Ask most philosophers for an example of a moral rationalist, and they will probably answer “Kant.” And no wonder. Kant’s first great work of moral philosophy, Groundwork of the Metaphysics of Morals, opens with a clarion call for rationalism, proclaiming the need to work out for once a pure moral philosophy, a metaphysics of morals. That this metaphysics includes the first principle of ethics, the moral law, is obvious. But what about the second principles, particular moral laws, such as duties (...) of truthfulness, beneficence, etc.? Are these principles metaphysical too? Many have thought not, since they make essential use of empirical and anthropological considerations. I argue otherwise; the second principles are metaphysical and this matters. I do this by taking seriously the metaphysics of the metaphysics of morals—more specifically, by understanding the metaphysics of morals alongside the metaphysics of nature. For, qua metaphysics, both employ a common two-stage methodology, the first stage of which is wholly a priori but the second stage of which is partly empirical. As I explain, appreciating this common methodology sheds new light on how the second principles are to be established, as well as on the reach of Kant’s rationalism. (shrink)

Providing heroin to heroin addicts taking part in medical trials to assess the effectiveness of the drug as a treatment alternative, breaches ethical research standards, some ethicists maintain. Heroin addicts, they say, are unable to consent voluntarily to take part in these trials. Other ethicists disagree. In our view, both sides of the debate have an inadequate understanding of voluntariness. In this article we therefore offer a fuller conception, one which allows for a more flexible, case-to-case approach in which some (...) heroin addicts are considered capable of consenting voluntarily, others not. An advantage of this approach, it is argued, is that it provides a safety net to minimize the risk of inflicting harm on trial participants. (shrink)

Shedding light on the political power and oppressive potential of language, theories of illocutionary silencing and discursive injustice show how gender, class and race can shape the pragmatics of speech, limiting in some circumstances the speaker’s ability to do things with her words. This article takes a close look at discursive injustice in trials for gender-based violence in connection with the phenomenon of misogyny. It argues that in the courtroom the testimony of the complainant is sometimes silenced by a sexist (...) ideology used in service of misogynistic ends. In particular, it argues that sexist social meanings can sometimes be enacted by the judge and accommodated by prosecutors, figuring as a component of the score in the language game of the trial and thus 1) determining what counts as sexual violence and 2) preventing complainants from making the moves they intend to make.

The role of imagination in Descartes. The critic of Sartre to the concept of image in Descartes.

A prominent view holds that perception and memory are distinguished at least partly by their temporal orientation: Perception functions to represent the present, while memory functions to represent the past. Call this view perceptual presentism. This chapter critically examines perceptual presentism in light of contemporary perception science. I adduce evidence for three forms of perceptual sensitivity to the past: (i) shaping perception by past stimulus exposure, (ii) recruitment of mnemonic representations in perceptual processing, and (iii) perceptual representation of present objects (...) as possessing past properties. I argue that forms (i) and (ii) are consistent with perceptual presentism, while form (iii) poses a genuine threat to the view. While the empirical case for form (iii) remains inconclusive, I suggest that the most serious challenges to perceptual presentism derive from representations that integrate mnemonic and present-tensed elements in the performance of canonical perceptual functions, such as perceiving object continuity over time.

Recently, the concept of "gender identity" has enjoyed a great deal of attention in gender metaphysics. This seems to be motivated by the goal of creating trans-inclusive theory, by explaining trans people's genders. In this paper, we aim to unmotivate this project. Notions of "gender identity" serve important pragmatic purposes for trans people, such as satisfying the curiosity of non-trans people, and, relatedly, securing our access to important goods like legal rights and medical care. However, we argue that this does (...) not mean that "gender identity" is a metaphysically substantial thing that deserves extensive theoretical attention. There are reasons to be skeptical of such a concept. We trace the history of "gender identity," primarily to identify its roots in trans-antagonistic medical theory and its connections to the problematic "wrong-body" model--a legacy that has pathologized and flattened trans experience. Moreover, we argue that trans people primarily use "gender identity" to explain ourselves to non-trans people, rather than to discuss ourselves among ourselves. Thus, we urge theorists to resist the urge to substantiate gender identity. Instead, we encourage the development of new and better concepts, ones that attend to the lived realities of trans community and the flourishing gender terms and practices that are constructed there. If these lived realities are taken seriously, there is no need to “explain” trans people’s genders; we can simply see them as they are. (shrink)

There is a widespread belief that for their own safety and for the protection of wildlife, cats should be permanently kept indoors. Against this view, I argue that cat guardians have a duty to provide their feline companions with outdoor access. The argument is based on a sophisticated hedonistic account of animal well-being that acknowledges that the performance of species-normal ethological behavior is especially pleasurable. Territorial behavior, which requires outdoor access, is a feline-normal ethological behavior, so when a cat is (...) permanently confined to the indoors, her ability to flourish is impaired. Since cat guardians have a duty not to impair the well-being of their cats, the impairment of cat flourishing via confinement signifies a moral failing. Although some cats assume significant risks and sometimes kill wild animals when roaming outdoors, these important considerations do not imply that all cats should be deprived of the opportunity to access the outdoors. Indeed, they do not, by themselves, imply that any cat should be permanently kept indoors. (shrink)

It is widely thought that there are limits to how things can perceptually appear to us. For instance, nothing can appear both square and circular, or both pure red and pure blue. Adam Pautz has dubbed such constraints “laws of appearance.” But if the laws of appearance obtain, then what explains them? Here I examine the prospects for an empirical explanation of the laws of appearance. First, I challenge extant empirical explanations that appeal purely to the format of perceptual representation. (...) I then develop a hybrid approach, on which the laws are explained not merely by format, but by two further factors: ecological constraints imposed by our environments, and computational constraints embodied by our perceptual systems. While the hybrid approach implies that the laws of appearance are contingent, I argue that this implication is empirically defensible, since even some of the most intuitively compelling laws have real-world counterexamples.

In this paper we consider the logics L(i,n) obtained from the (n+1)-valued Lukasiewicz logics L(n+1) by taking the order filter generated by i/n as the set of designated elements. In particular, the conditions of maximality and strong maximality among them are analyzed. We present a very general theorem that provides sufficient conditions for maximality between logics. As a consequence of this theorem, it is shown that L(i,n) is maximal w.r.t. CPL whenever n is prime. Concerning strong maximality (i.e. maximality w.r.t. (...) rules instead of only axioms), we provide algebraic arguments in order to show that the logics L(i,n) are not strongly maximal w.r.t. CPL, even for n prime. Indeed, in such case, we show that there is just one extension between L(i,n) and CPL obtained by adding to L(i,n) a kind of graded explosion rule. Finally, using these results, we show that the logics L(i,n) with n prime and i/n < 1/2 are ideal paraconsistent logics. (shrink)

Is practical reason a cognitive faculty? Do practical judgments make claims about a subject matter that are appropriately assessed in terms of their agreement with that subject matter? According to Kantians like Christine Korsgaard, the answer is no. To think otherwise is to conflate the theoretical and the practical, the epistemic and the ethical. I am not convinced. In this paper, I motivate my skepticism through examination of the very figure who inspires Korsgaard’s rejection of cognitivism: Kant. For as I (...) read him, Kant does not construe the distinction between theoretical and practical reason in terms of a distinction between cognitive and non-cognitive faculties but in terms of two distinct applications of a single faculty of reason, which is through-and-through cognitive. Thus, practical, no less than theoretical, reason cognizes a subject matter, and so practical, no less than theoretical, reason is straightforwardly subject to familiar epistemic standards of truth, warrant, and knowledge. Of course, even if I am right about Kant, this does not show that Korsgaard is wrong about reason; and I will offer no direct argument against her position here. Nonetheless, I believe that reflection on Kant’s true view, with its careful treatment of and respect for both the practicality and rationality of reason, should perhaps lead us to rethink what it means to be a rationalist in ethics.

When we perceive an object, we perceive the object from a perspective. As a consequence of the perspectival nature of perception, when we perceive, say, a circular coin from different angles, there is a respect in which the coin looks circular throughout, but also a respect in which the coin's appearance changes. More generally, perception of shape and size properties has both a constant aspect—an aspect that remains stable across changes in perspective—and a perspectival aspect—an aspect that changes depending on (...) one's perspective on the object. How should we account for the perspectival aspect of spatial perception? We present a framework within which to discuss the perspectival aspect of perception and put forward three desiderata that any account of the perspectival aspect of perception should satisfy. We discuss views on which the perspectival aspect of perception is analyzed in terms of constitutively mind-dependent appearance properties as well as views on which the perspectival aspect of perception is analyzed in terms of representations of mind-independent perspectival properties.

Contrary to what he expected, Primo Levi didn’t experience his life after being released from Auschwitz as cheerful and light-hearted. He – like many other survivors – was haunted by an obscure and solid anguish. It took some effort for him to discern the object or source of this anguish. He finally identified it as springing from a sense of shame or guilt in front of the drowned, that is, of those who were exterminated in the Lager. He could not (...) determine, however, whether his shame or guilt was at all rational. In this paper l examine Levi’s shame in light of what I regard as the dominant conception of practical deliberation, according to which principles and emotional detachment are central to our ability to deliberate appropriately. This conception underlies the role that John Rawls ascribes to the original position in the determination of the fundamental principles of justice. Deliberation in the original position is supposed to abstract away from any particular moral situations that one may actually have faced, since these are purely circumstantial elements to be discarded as both irrelevant and misleading for a proper deliberation on the principles of justice. In this paper, I intend both to make a case against the conception of practical deliberation on which Rawls’ original position relies and to vindicate the rationality of Levi’s shame, once some well-entrenched assumptions are brought to light and challenged.

The ability to perceive the shapes of things as enduring through changes in how they stimulate our sense organs is vital to our sense of stability in the world. But what sort of capacity is shape constancy, and how is it reflected in perceptual experience? This paper defends a pluralist account of shape constancy: There are multiple kinds of shape constancy centered on geometrical properties at various levels of abstraction, and properties at these various levels feature in the content of (...) perceptual experience, governing patterns of apparent shape similarity. I propose that the varieties of shape constancy are subserved by the syntactic complexity of perceptual shape representations. By assigning discrete constituents to various abstract shape parameters, these representations attune us to the preservation of certain abstract shape properties through changes in more determinate shape properties. Finally, I draw broader lessons concerning the nature and function of perceptual constancy. (shrink)

Logical realism is a view about the metaphysical status of logic. Common to most if not all the views captured by the label ‘logical realism’ is that logical facts are mind- and language-independent. But that does not tell us anything about the nature of logical facts or about our epistemic access to them. The goal of this paper is to outline and systematize the different ways that logical realism could be entertained and to examine some of the challenges that these (...) views face. It will be suggested that logical realism is best understood as a metaphysical view about the logical structure of the world, but this raises an important question: does logical realism collapse into standard metaphysical realism? It will be argued that this result can be accommodated, even if it cannot be altogether avoided. (shrink)

Causal closure arguments against interactionist dualism are currently popular amongst physicalists. Such an argument appeals to some principles of the causal closure of the physical, together with certain other premises, to conclude that at least some mental events are identical with physical events. However, it is crucial to the success of any such argument that the physical causal closure principle to which it appeals is neither too strong nor too weak by certain standards. In this paper, it is argued that (...) various forms of naturalistic dualism, of an emergentist character, are consistent with the strongest physical causal closure principles that can plausibly be advocated.
