We take up the challenge of developing an international network with capacity to survey the world's scientists on an ongoing basis, providing rich datasets regarding the opinions of scientists and scientific sub-communities, both at a time and also over time. The novel methodology employed sees local coordinators, at each institution in the network, sending survey invitation emails internally to scientists at their home institution. The emails link to a ‘10 second survey’, where the participant is presented with a single statement (...) to consider, and a standard five point Likert scale. In June 2023, a group of 30 philosophers and social scientists invited 20,085 scientists across 30 institutions in 12 countries to participate, gathering 6,807 responses to the statement 'Science has put it beyond reasonable doubt that COVID-19 is caused by a virus'. The study demonstrates that it is possible to establish a global network to quickly ascertain scientific opinion on a large international scale, with high response rate, low opt-out rate, and in a way that allows for significant (perhaps indefinite) repeatability. Measuring scientific opinion in this new way would be a valuable complement to currently available approaches, potentially informing policy decisions and public understanding across diverse fields.

Philosophy has long been seen as a crucial instrument for living a meaningful life. Nonetheless, for more than a decade, systematic philosophical study in Africa has been dominated by a single compound question: Is there an African philosophy, and if so, what is its nature? When it comes to Africa and philosophy, there is a lot of debate about whether or not Africans have a philosophy. Africans have long been accused of being irrational. Some Western scholars’ interpretations of African philosophy (...) may help us comprehend it better. The Aime Cesaire-led Negritude movement, the Harlem Revolution, the South African Apartheid movement, and others are all examples of recent literature expressing opposition to the perspective of black inferiority and various insults directed at black Africans. Some European scholars did accuse Africans of being irrational beings. These claims provided the impetus for the spread of various beliefs and ideologies masquerading as African philosophy. In light of this, the purpose of this essay is to disprove prejudicial claims made against Africans and African philosophy. The works of Western thinkers such as Immanuel Kant, Georg W. F. Hegel, and Lucien Levy-Bruhl would be highlighted. (shrink)

In this chapter I critically discuss the dismissal of the philosophical significance of facts about human evolution and historical development in the work of W. D Ross. I address Ross’s views about the philosophical significance of the emerging human sciences of his time in two of his main works, namely The Right and the Good and The Foundations of Ethics. I argue that the debate between Ross and his chosen interlocutors (Herbert Spencer, Emile Durkheim and Lucien Levy-Bruhl) shows striking (...) similarities with parallel debates in contemporary moral philosophy.

The idea that in human history it is possible to recognize distinct ways of thinking is widespread in the literature. Sometimes, instead of the phrase ‘ways of thinking’, other labels are used, such as ‘forms of thought’, ‘modes of thinking’, ‘ways of knowing’, ‘ways of reasoning’, ‘mental attitudes’ or ‘worldviews’. At any rate, it is possible to say that there is a concept, that of ‘ways of thinking’, which has played a crucial role in philosophy at least since the Enlightenment (...) and has acquired considerable weight with the emergence of a French tradition in philosophy of science called historical epistemology. This concept appears in different versions, as if they were species of the same genus. In this chapter, I shall outline its history, from Vico to Hacking and beyond, and I shall show how and why its different species have been introduced. My account provides a guiding thread running through philosophy of science that unifies the researches of important authors such as Lévy-Bruhl, Brunschvicg, Metzger, Koyré, Fleck, Foucault, Kuhn, Hacking and others. This guiding thread is mainly constituted by the project of historicizing Kant’s a priori by replacing it with a given notion of ‘ways of thinking’. (shrink)

cinematic proposition to the field of philosophical cinema and literature, in hommage to Henry-Lévi.

The following is a transcript of the interview I (Yasuko Kitano) conducted with Neil Levy (The Centre for Applied Philosophy and Public Ethics, CAPPE) on the 23rd in July 2009, while he was in Tokyo to give a series of lectures on neuroethics at The University of Tokyo Center for Philosophy. I edited his words for publication with his approval.

Many biological investigations are organized around a small group of species, often referred to as ‘model organisms’, such as the fruit fly Drosophila melanogaster. The terms ‘model’ and ‘modelling’ also occur in biology in association with mathematical and mechanistic theorizing, as in the Lotka–Volterra model of predator-prey dynamics. What is the relation between theoretical models and model organisms? Are these models in the same sense? We offer an account on which the two practices are shown to have different epistemic characters. (...) Theoretical modelling is grounded in explicit and known analogies between model and target. By contrast, inferences from model organisms are empirical extrapolations. Often such extrapolation is based on shared ancestry, sometimes in conjunction with other empirical information. One implication is that such inferences are unique to biology, whereas theoretical models are common across many disciplines. We close by discussing the diversity of uses to which model organisms are put, suggesting how these relate to our overall account. 1 Introduction2 Volterra and Theoretical Modelling3 Drosophila as a Model Organism4 Generalizing from Work on Model Organisms5 Phylogenetic Inference and Model Organisms6 Further Roles of Model Organisms6.1 Preparative experimentation6.2 Model organisms as paradigms6.3 Model organisms as theoretical models6.4 Inspiration for engineers6.5 Anchoring a research community7 Conclusion.

Evolutionary debunking arguments appeal to selective etiologies of human morality in an attempt to undermine moral realism. But is morality actually the product of evolution by natural selection? Although debunking arguments have attracted considerable attention in recent years, little of it has been devoted to whether the underlying evolutionary assumptions are credible. In this paper, we take a closer look at the evolutionary hypotheses put forward by two leading debunkers, namely Sharon Street and Richard Joyce. We raise a battery of (...) considerations, both empirical and theoretical, that combine to cast doubt on the plausibility of both hypotheses. We also suggest that it is unlikely that there is in the vicinity a plausible alternative hypothesis suitable for the debunker’s cause. (shrink)

Thought experiments play a role in science and in some central parts of contemporary philosophy. They used to play a larger role in philosophy of science, but have been largely abandoned as part of the field’s “practice turn”. This chapter discusses possible roles for thought experimentation within a practice-oriented philosophy of science. Some of these roles are uncontroversial, such as exemplification and aiding discovery. A more controversial role is the reliance on thought experiments to justify philosophical claims. It is proposed (...) that if we adopt an underlying empiricist view of concepts, then thought experiments can be seen as affording us contact with scientific practice, despite their seemingly a priori character. The advantages and drawbacks of thought experiments are discussed via comparison with case studies, on the one, and simulations on the other hand. The chapter closes with some remarks on how to combine thought experiments with other methods. (shrink)

Actions performed in a state of automatism are not subject to moral evaluation, while automatic actions often are. Is the asymmetry between automatistic and automatic agency justified? In order to answer this question we need a model or moral accountability that does justice to our intuitions about a range of modes of agency, both pathological and non-pathological. Our aim in this paper is to lay the foundations for such an account.

O termo “cogito” designa de modo genérico e impreciso um argumento que Descartes propõe em diversos momentos de sua obra. De um modo geral, os comentadores, tal como o fizeram os interlocutores contemporâneos ao autor, consideram que a expressão “penso, logo existo” (cogito ergo sum), ausente das Meditações Metafísicas, resume adequadamente este argumento único e procuram esclarecê-lo ou criticá-lo, nem sempre levando em consideração as diferentes formulações que recebe e os diferentes contextos em que ocorre. Meu objetivo neste texto é (...) simplesmente analisar o quarto parágrafo da Segunda Meditação (AT VII, 24-25; IX-1,19), no qual ele supostamente apresenta este mesmo argumento sem empregar a famosa expressão. Das muitas, diversas e relevantes questões filosóficas que este argumento suscita, gostaria de me concentrar em investigar se ele pode ser reconstruído sem que seja necessário introduzir – como uma premissa não justificada – a concepção do pensamento como sendo essencialmente consciência de si e, portanto, como envolvendo - por definição, a auto-referência imediata e incorrigível do sujeito a si mesmo. Gostaria de poder mostrar que o argumento não apenas independe dessa concepção como, além disso, conduz a essa concepção; todavia, somente o primeiro passo em direção a esta interpretação será dado neste artigo. Quanto à expressão “penso, logo existo”, minha hipótese é que, embora ausente do texto, ela, de fato, resume o sentido geral da posição cartesiana. Sua ausência explica-se pelo fato de que Descartes pretende apresentar nas Meditações a versão mais completa de seu argumento e a passagem que será aqui analisada constitui, na realidade, apenas uma primeira etapa dessa versão. A análise e a reconstrução que serão propostas supõe que o argumento apresentado no parágrafo 4 deva ser compreendido, como propõe H. G. Frankfurt, como composto de quatro etapas, cujo sentido depende do contexto argumentativo mais amplo no qual estão inseridas, como observou Jean-Claude Pariente, em seu artigo sobre o cogito nas Meditações Metafísicas. Nesse sentido, a estrutura do presente artigo seguirá essas etapas. (shrink)

Recently, various philosophers have argued that we can obtain knowledge via the imagination. In particular, it has been suggested that we can come to know concrete, empirical matters of everyday significance by appropriately imagining relevant scenarios. Arguments for this thesis come in two main varieties: black box reliability arguments and constraints-based arguments. We suggest that both strategies are unsuccessful. Against black-box arguments, we point to evidence from empirical psychology, question a central case-study, and raise concerns about a (claimed) evolutionary rationale (...) for the imagination's reliability. Against the constraints-based account, we argue that to the extent that it works, this does not give rise to knowledge that is distinctively from the imagination. We conclude by suggesting that the imagination's role in raising possibilities, traditionally seen as part of the context of discovery, can in fact play a role in justification, including as a bulwark against certain sorts of skepticism.

Philosophical orthodoxy has it that intentional action consists in one’s intention appropriately causing a motion of one’s body, placing the latter as (conceptually and/or metaphysically) prior to the former. Here I argue that this standard schema should be reversed: acting intentionally is at least conceptually prior to intending. The argument is modelled on a Williamsonian argument for the priority of knowledge developed by Jenifer Nagel. She argues that children acquire the concept KNOWS before they acquire BELIEVES, building on this alleged (...) developmental priority of knowledge to establish its conceptual priority. I start by taking a closer look at Nagel’s argument, canvassing extant objections to do both with the empirical adequacy of her claims and their philosophical implications. Doing so allows me in the second part of the paper to draw lessons that inform the construction of a revamped parallel argument for the priority of ACTS INTENTIONALLY. (shrink)

Many have expected that understanding the evolution of norms should, in some way, bear on our first-order normative outlook: How norms evolve should shape which norms we accept. But recent philosophy has not done much to shore up this expectation. Most existing discussions of evolution and norms either jump headlong into the is/ought gap or else target meta-ethical issues, such as the objectivity of norms. My aim in this paper is to sketch a different way in which evolutionary considerations can (...) feed into normative thinking—focusing on stability. I will discuss two forms of argument that utilize information about social stability drawn from evolutionary models, and employs it to assess claims in political philosophy. One such argument treats stability as feature of social states that may be taken into account alongside other features. The other uses stability as a constraint on the realization of social ideals, via a version of the ought-implies-can maxim. These forms of argument are not new; indeed they have a history going back at least to early modern philosophy. But their marriage with evolutionary information is relatively recent, has a significantly novel character, and has received little attention in recent moral and political philosophy. (shrink)

A number of concerns have been raised about the possible future use of pharmaceuticals designed to enhance cognitive, affective, and motivational processes, particularly where the aim is to produce morally better decisions or behavior. In this article, we draw attention to what is arguably a more worrying possibility: that pharmaceuticals currently in widespread therapeutic use are already having unintended effects on these processes, and thus on moral decision making and morally significant behavior. We review current evidence on the moral effects (...) of three widely used drugs or drug types: propranolol, selective serotonin reuptake inhibitors, and drugs that effect oxytocin physiology. This evidence suggests that the alterations to moral decision making and behavior caused by these agents may have important and difficult-to-evaluate consequences, at least at the population level. We argue that the moral effects of these and other widely used pharmaceuticals warrant further empirical research and ethical analysis. (shrink)

Recent work in neuroimaging suggests that some patients diagnosed as being in the persistent vegetative state are actually conscious. In this paper, we critically examine this new evidence. We argue that though it remains open to alternative interpretations, it strongly suggests the presence of consciousness in some patients. However, we argue that its ethical significance is less than many people seem to think. There are several different kinds of consciousness, and though all kinds of consciousness have some ethical significance, different (...) kinds underwrite different kinds of moral value. Demonstrating that patients have phenomenal consciousness — conscious states with some kind of qualitative feel to them — shows that they are moral patients, whose welfare must be taken into consideration. But only if they are subjects of a sophisticated kind of access consciousness — where access consciousness entails global availability of information to cognitive systems — are they persons, in the technical sense of the word employed by philosophers. In this sense, being a person is having the full moral status of ordinary human beings. We call for further research which might settle whether patients who manifest signs of consciousness possess the sophisticated kind of access consciousness required for personhood. (shrink)

There has been a resurgence of interest lately within philosophy of mind and action in the category of mental action. Against this background, the present paper aims to question the very possibility, or at least the theoretical significance, of teasing apart mental and bodily acts. After raising some doubts over the viability of various possible ways of drawing the mental act/bodily act distinction, the paper draws some lessons from debates over embodied cognition, which arguably further undermine the credibility of the (...) distinction. The insignificance of the distinction is demonstrated in part by showing how the focus on ‘inner’ acts hampers fruitful discussion of Galen Strawson’s skepticism of mental agency. Finally, the possibility is discussed that a distinction between covert and overt action should supplant the one between mental and bodily action. (shrink)

Henri Lefebvre has considerable claims to be the greatest living philosopher. His work spans some sixty years and includes original work on a diverse range of subjects, from dialectical materialism to architecture, urbanism and the experience of everyday life. The Production of Space is his major philosophical work and its translation has been long awaited by scholars in many different fields. The book is a search for a reconciliation between mental space and real space. In the course of his (...) exploration, Henri Lefebvre moves from metaphysical and ideological considerations of the meaning of space to its experience in the everyday life of home and city. He seeks, in other words, to bridge the gap between the realms of theory and practice, between the mental and the social, and between philosophy and reality. In doing so, he ranges through art, literature, architecture and economics, and further provides a powerful antidote to the sterile and obfuscatory methods and theories characteristic of much recent continental philosophy. This is a work of great vision and incisiveness. It is also characterized by its author's wit and by anecdote, as well as by a deftness of style which Donald Nicholson-Smith's sensitive translation precisely captures. (shrink)

Moral realism is often taken to have common sense and initial appearances on its side. Indeed, by some lights, common sense and initial appearances underlie all the central positive arguments for moral realism. We offer a kind of debunking argument, taking aim at realism’s common sense standing. Our argument differs from familiar debunking moves both in its empirical assumptions and in how it targets the realist position. We argue that if natural selection explains the objective phenomenology of moral deliberation and (...) judgement, then this undermines arguments from that phenomenology. This results in a simpler, and in some ways more direct, challenge to realism. It is also less vulnerable to the main objections that have been leveled against such arguments. If accepted, our conclusion should make a real difference to the dialectic in this area. It means that neither realism nor its denial is the default, to-be-refuted, position. (shrink)

I distinguish three theses associated with the new mechanistic philosophy – concerning causation, explanation and scientific methodology. Advocates of each thesis are identified and relationships among them are outlined. I then look at some recent work on natural selection and mechanisms. There, attention to different kinds of New Mechanism significantly affects of what is at stake.

How does valuing something for its own sake differ from valuing an entity for the sake of other things? Although numerous answers come to mind, many of them rule out substantive views about what is valuable for its own sake. I therefore seek to provide a more neutral way to distinguish the two valuing attitudes. Drawing from existing accounts of valuing, I argue that the two can be distinguished in terms of a conative-volitional feature. Focusing first on “non-final valuing”—i.e. valuing_ (...) x_ for the sake of something else—I argue that it involves adopting certain reasons on account of a desire for _x_ to contribute to other things. I then show how this contrasts final valuing. The result, I argue, is a plausible account of how the two modes of valuing differ that leaves open substantive views about what all can be valued for its own sake. This is helpful because it develops a popular methodology used to explore the value of a wide range of things, including natural entities, family heirlooms, and artworks, as well as, more broadly, entities that might have “extrinsic final value.”.

In this chapter, we argue for three theses: (1) we lack the power to form beliefs at will (i.e., directly); at very least, we lack the power to form at will beliefs of the kind that proponents of doxastic voluntarism have in mind; but (2) we possess a propensity to form beliefs for non-epistemic reasons; and (3) these propensities—once we come to know we have them—entail that we have obligations similar to those we would have were doxastic voluntarism true. Specifically, (...) we will argue that we have obligations to avoid triggering these propensities to form beliefs that are unwarranted or even immoral. (shrink)

Intention Cognitivism – the doctrine that intending to V entails, or even consists in, believing that one will V – is an important position with potentially wide-ranging implications, such as a revisionary understanding of practical reason, and a vindicating explanation of 'Practical Knowledge'. In this paper, I critically examine the standard arguments adduced in support of IC, including arguments from the parity of expression of intention and belief; from the ability to plan around one's intention; and from the explanation provided (...) by the thesis for our knowledge of our intentional acts. I conclude that none of these arguments are compelling, and therefore that no good reason has been given to accept IC. (shrink)

I argue for three conclusions. First, responsibility skeptics are committed to the position that the criminal justice system should adopt a universal nonresponsibility excuse. Second, a universal nonresponsibility excuse would diminish some of our most deeply held values, further dehumanize criminals, exacerbate mass incarceration, and cause an even greater number of innocent people (nonwrongdoers) to be punished. Third, while Saul Smilansky's ‘illusionist’ response to responsibility skeptics – that even if responsibility skepticism is correct, society should maintain a responsibility‐realist/retributivist criminal justice (...) system – is generally compelling, it would not work if a majority of society were to convert, theoretically and psychologically, to responsibility skepticism. In this (highly improbable) scenario, and only in this (highly improbable) scenario, the criminal justice system would need to be reformed in such a way that it aligned with the majority's responsibility‐skeptical beliefs and attitudes.

The external world sceptic tells some familiar narratives involving massive deception. Perhaps we are brains in vats. Perhaps we are the victim of a deceitful demon. You know the drill. The sceptic proceeds by observing first that victims of such deceptions know nothing about their external environment and that second, since we cannot rule out being a victim of such deceptions our- selves, our own external world beliefs fail to attain the status of knowledge. Discussions of global external world scepticism (...) tend to focus on the second step, where a number of well-known lines of resistance have been offered. But there has been little attention to the first, seemingly innocuous step. That will be the focus of this paper. Part one – sections 1, 2, and 3 – will explain why these standard narratives are not convincing examples of cases where there is no knowledge of the external world. In part two – section 4 – we shall undertake a useful case study. David Lewis’s ‘Elusive Knowledge’ is often thought of as presenting an epistemological vision that is somewhat friendly to external world scepticism: as Lewis himself presents things, there are contexts where external world knowledge ascriptions are uniformly false, and where true knowledge ascriptions are limited to either axiomatic truths or truths about our inner life. We examine his discussion in the light of the preceding reflections and show that the framework he presents is not so concessionary to global external world scepticism after all. (shrink)

Um argumento esquecido em um verdadeiro arsenal de guerra que Espinosa se dedicou a reunir contra o que considerava um dos maiores, senão o maior, empecilho para que os homens alcançassem a verdadeira felicidade, a saber, o falso conceito que possuem da liberdade humana quando a tomam por uma liberdade de arbítrio, contrária a toda e qualquer necessidade. Argumento forjado, certamente, com boa dose de ironia e ânimo polemista contra um objetor que se diz defensor do cartesianismo, e, portanto, em (...) certa medida contra Descartes. Apresentar um argumento que envolva a referência a situações oníricas contra a concepção cartesiana de liberdade como poder dos contrários é, certamente, pretender fazer o feitiço virar contra o feiticeiro. No entanto, para além desse encanto particular e quase anedótico, creio que esse argumento contribui com um bom ponto à inesgotável discussão sobre a natureza da liberdade, debate caro às inquietações filosóficas do nosso querido amigo. Ponto para cuja elucidação espero poder contar com sua ajuda, pois, como se poderá ver na sequência, minha compreensão do argumento é ainda bastante preliminar. Duas traduções porque as cartas onde esse argumento muito provavelmente surgiu pela primeira vez não contam ainda, até onde eu saiba, com uma tradução para a língua portuguesa que permita um acesso mais fácil ao pensamento do filósofo.

The Hodgkin–Huxley (HH) model of the action potential is a theoretical pillar of modern neurobiology. In a number of recent publications, Carl Craver ([2006], [2007], [2008]) has argued that the model is explanatorily deficient because it does not reveal enough about underlying molecular mechanisms. I offer an alternative picture of the HH model, according to which it deliberately abstracts from molecular specifics. By doing so, the model explains whole-cell behaviour as the product of a mass of underlying low-level events. The (...) issue goes beyond cellular neurobiology, for the strategy of abstraction exhibited in the HH case is found in a range of biological contexts. I discuss why it has been largely neglected by advocates of the mechanist approach to explanation. 1 Introduction2 A Primer on the HH Model2.1 The basic qualitative picture2.2 The quantitative model3 Interlude: What Did Hodgkin and Huxley Think?4 Craver’s View4.1 Mechanistic explanation4.2 Sketches4.3 Craver's view: The HH model as a mechanism sketch5 An Alternative View of the HH Model5.1 Another look at the equations5.2 The discrete-gating picture5.3 The road paved by Hodgkin and Huxley5.4 Summary and comparison to Craver6 Conclusion: The HH Model and Mechanistic Explanation6.1 Sketches and abstractions6.2 Why has aggregative abstraction been overlooked?

The paper proposes a novel solution to the problem of the time of a killing (ToK), which persistently besets theories of act-individuation. The solution proposed claims to expose a crucial wrong-headed assumption in the debate, according to which ToK is essentially a problem of locating some event that corresponds to the killing. The alternative proposal put forward here turns on recognizing a separate category of dynamic occurents, viz. processes. The paper does not aim to mount a comprehensive defense of process (...) ontology, relying instead on extant defenses. The primary aim is rather to put process ontology to work in diagnosing the current state of play over ToK, and indeed in solving it. (shrink)

I introduce game-theoretic models for threats to the discussion of threats in speech act theory. I first distinguish three categories of verbal threats: conditional threats, categorical threats, and covert threats. I establish that all categories of threats can be characterized in terms of an underlying conditional structure. I argue that the aim—or illocutionary point—of a threat is to change the conditions under which an agent makes decisions in a game. Threats are moves in a game that instantiate a subgame in (...) which the addressee is ‘under threat’. (shrink)

Mind wandering has been a target of a fast-expanding area of research in cognitive science and philosophy. One of the central puzzles that researchers have been grappling with is whether this mental process should be thought of as passive or active in nature. Intuitively, a wandering mind seems passive but mounting empirical evidence suggests otherwise. Irving (2021) defends a prominent account of mind wandering as unguided attention, which aims inter alia to resolve the puzzle. However, I present counterexamples that reveal (...) Irving’s account to be both too weak and too strong. I then develop the alternative proposal that (stated roughly) mind wandering consists in voluntarily passive attention. After unpacking and defending this idea, I show how it helps to eliminate the conflicting appearance of mind wandering as both passive and active. (shrink)

I defend an interpretation of the first Critique’s category of totality based on Kant’s analysis of totality in the third Critique’s Analytic of the mathematical sublime. I show, firstly, that in the latter Kant delineates the category of totality — however general it may be — in relation to the essentially singular standpoint of the subject. Despite the fact that sublime and categorial totality have a significantly different scope and function, they do share such a singular baseline. Secondly, I argue (...) that Kant’s note (in the first Critique’s metaphysical deduction) that deriving the category of totality requires a special act of the understanding can be seen as a ‘mark’ of that singular baseline. This way, my aesthetical ‘detour’ has the potential of revealing how the subjective aspects of object-constitution might be accounted for in the very system of the categories (of quantity) itself.

This paper explores some consequences of Lewis’s (Australas J Philos 74(4):549–567, 1996) understanding of how knowledge is compartmentalized. It argues, first, that he underestimates how badly it impacts his view. When knowledge is compartmentalized, it lacks at least one of two essential features of Lewis’s account: (a) Elusiveness—familiar skeptical possibilities, when relevant, are incompatible with everyday knowledge. (b) Knowledge is a modality—when a thinker knows that p, there is no relevant possibility where p is false. Lewis proposes compartmentalized knowledge to (...) keep treating knowledge as a modality while mitigating one of its unrealistic epistemological implications: In normal modal epistemic logic (and standard possible world semantics), a thinker always counts as knowing the strongest proposition that follows from the set of all the individual propositions that this thinker knows. Lewis’s compartmentalization proposal is that thinkers merely know the conjunctions of propositions that are known in each of, but not across, their compartments. The irony is that in avoiding overblown knowledge the view now allows for thinkers to attend to skeptical error possibilities and yet knowledge is present. The account avoids inflation of knowledge in one sense only to acquire another type of knowledge the view denies subjects can have. This problem motivates an inspection of knowledge accounts whose intra-compartment closure principles are weaker than those that are valid in normal modal-logic. The conclusion is that some formulations of closure can avoid the challenge Lewis’s view faces. Nevertheless, even these closure principles pose a barrier—perhaps an implausible barrier—for knowledge of ignorance. Even when the reasoning supporting the lack of knowledge is sound, a subject cannot always know she doesn’t know. Interestingly, this obstacle is one that knowledge of knowledge doesn’t seem to face.

Many have the intuition that human persons are both extremely and equally valuable. This seeming extremity and equality of vale is puzzling: if overall value is the sum of one’s final value and instrumental value, how could it be that persons share the same extreme value? One way that we can solve the Value Puzzle is by following Andrew Bailey and Josh Rasmussen. Philosophy and Phenomenological Research, 103, 264–277 (2020) and accepting that persons have infinite final value. But there are (...) some significant downsides to their way of thinking about values, which relies on the extended real numbers. We offer a different approach: if we model values using the hyperreal numbers, we can capture many of our intuitions about the extremity and relative equality of human value without incurring the substantial theoretical costs of using the extended real numbers. We also examine other ways of modeling the infinite value of persons and evaluate the strengths and weaknesses of these other accounts compared to ours. (shrink)

Some philosophers of science – the present author included – appeal to fiction as an interpretation of the practice of modeling. This raises the specter of an incompatibility with realism, since fiction-making is essentially non-truth-regulated. I argue that the prima facie conflict can be resolved in two ways, each involving a distinct notion of fiction and a corresponding formulation of realism. The main goal of the paper is to describe these two packages. Toward the end I comment on how to (...) choose among them. (shrink)

This paper aims to make progress in understanding the nature of reasoning. Its primary goal is to spell out and defend a novel account of what reasoning might be, in terms of how reasoning contributes to settling (practical and theoretical) inquiries. Prior to spelling out this constructive proposal, however, the paper problematizes a very common picture of reasoning in an attempt to demonstrate the need for an alternative approach. The overarching argument of the paper is comprised of three stages. The (...) first attacks the predominant conception of reasoning for its specious restriction to fully conscious and explicit episodes. The second stage offers a replacement for this faulty conception, according to which a reasoning agent is one who may be represented as if she were undergoing a fully conscious and explicit process. Finally, the last stage proposes one way to fill in the above schema, articulating and defending conditions for representing agents as reasoning fully consciously and explicitly. Each of the above stages is independent of the others: One may accept that reasoning need not be conscious and explicit but reject the schema proposed as a replacement; and again, the schema may be accepted but not the particular proposal for filling it in.

To a large extent, the evidential base of claims in the philosophy of science has switched from thought experiments to case studies. We argue that abandoning thought experiments was a wrong turn, since they can effectively complement case studies. We make our argument via an analogy with the relationship between experiments and observations within science. Just as experiments and ‘natural’ observations can together evidence claims in science, each mitigating the downsides of the other, so too can thought experiments and case (...) studies be mutually supporting. After presenting the main argument, we look at potential concerns about thought experiments, suggesting that a judiciously applied mixed-methods approach can overcome them. (shrink)

At a House hearing on December 5, 2023, the presidents of three universities—Harvard, MIT, and the University of Pennsylvania—refused to state that certain kinds of hate speech, specifically calls for genocide of Jews, are prohibited on their campuses. The backlash against two of them, Harvard’s Claudine Gay and Penn’s Liz Magill, was swift and devastating; both of them were successfully pressured to resign. Still, while Professors Gay’s and Magill’s responses were widely criticized as tone-deaf, they were legally correct. At many (...) private, and all public, colleges and universities, even the worst hate speech is generally protected unless it is accompanied by aggressive, threatening, or violent conduct. -/- These “demotions” augur even worse consequences, including termination, for less powerful faculty who say the “wrong” thing, in particular statements in support of Trumpism, an increasingly mainstream ideology that stitches together white supremacy, misogyny, a preference for autocracy over democracy, and several phobias—homophobia, Islamophobia, transphobia, and xenophobia. The question I address in this paper is whether these consequences are constitutional at public schools. Whose right is stronger—a public-school teacher’s First Amendment right to express pro-Trumpist sentiments or a public school’s right to maintain a fair, inclusive, and welcoming learning environment? In this article, I argue that the public school has the upper hand here, that it is indeed constitutionally permitted to prohibit political hate speech that contributes to a hostile learning environment. Still, I narrowly limit this prohibition to dehumanizing speech—that is, speech explicitly suggesting that some human beings are “lesser”, intrinsically less valuable, than other human beings. -/- One objection to this position is that public schools may not prohibit any speech, no matter how dehumanizing, because such prohibition amounts to constitutionally impermissible viewpoint discrimination. I argue, however, that viewpoint discrimination is an integral part of education and therefore constitutionally permissible. Education necessarily involves promoting some values over others. These values fall into seven categories: constitutional principles, the humanist virtues, successful character traits and behaviors, knowledge and truth, art and beauty, health (both mental and physical), and social goods (such as justice, peace, and rule of law).

Response to commentary. We are grateful to Crockett and Craigie for their interesting remarks on our paper. We accept Crockett’s claim that there is a need for caution in drawing inferences about patient groups from work on healthy volunteers in the laboratory. However, we believe that the evidence we cited established a strong presumption that many of the patients who are routinely taking a medication, including many people properly prescribed the medication for a medical condition, have morally significant aspects of (...) their cognition and behavior modified in a way that is unintended and may sometimes be unwelcome. Crockett notes that in some cases the effects of long-term drug use may differ, sometimes markedly, from the effects of short-term use. However, if acute use of a drug affects a neural system involved in mediating moral cognition or behavior, this nevertheless provides some evidence that chronic use of the drug may affect that same system and thus have morally significant effects. It is also plausible, in some cases, that an acute moral effect would give rise to a chronic moral effect via cognitive mechanisms. ... (shrink)

Nesse primeiro momento da análise do problema da liberdade em Espinosa, gostaria de mostrar que, embora Espinosa trate o conceito de contingência como relacionado à finitude do entendimento humano, o que sugere uma abordagem meramente negativa, ele, na verdade, desenvolve uma abordagem positiva, a saber : a contingência, assim como o tempo , é uma forma necessária do pensamento humano que tem um fundamento na realidade das coisa s às quais ele se aplica, embora não possa ser considerado uma propriedade (...) das coisas. Mostrar que a contingência , assim como o conceito de tempo, é uma forma necessária do pensamento humano significa mostrar não apenas que existem condições objetivas que autorizam a aplicação desse conceito, mas que a imperfeição na qual se funda o conceito de contingência é necessária e intransponível para o entendimento humano. -/- O primeiro passo será estabelecido a partir da prova de que a categorização temporal, da qual a contingência é uma das formas , tem por fundamento o estatuto ontológico peculiar das coisas sobre as quais ela incide, a saber, sobre o estatuto modal (não-substancial) das coisas singulares, unicamente no qual é possível distinguir entre a essência e a existência. O segundo passo consistirá em mostrar que a categorização temporal é uma forma necessária do conhecimento que o homem tem do mundo na medida em que ela é uma das atividades constitutiva s da unidade numérica da alma humana, ou seja, uma das atividades pelas quais a alma humana existe em ato na duração.

Science and fiction seem to lie at opposite ends of the cognitive-epistemic spectrum. The former is typically seen as the study of hard, real-world facts in a rigorous manner. The latter is treated as an instrument of play and recreation, dealing in figments of the imagination. Initial appearances notwithstanding, several central features of scientific modeling in fact suggest a close connection with the imagination and recent philosophers have developed detailed accounts of models that treat them, in one way or another, (...) as akin to fictions. This chapter will critically discuss the fictions approach as an epistemology of scientific modeling. (shrink)

The nature of attention has been the topic of a lively research programme in psychology for over a century. But there is widespread agreement that none of the theories on offer manage to fully capture the nature of attention. Recently, philosophers have become interested in the debate again after a prolonged period of neglect. This paper contributes to the project of explaining the nature of attention. It starts off by critically examining Christopher Mole’s prominent “adverbial” account of attention, which traces (...) the failure of extant psychological theories to their assumption that attending is a kind of process. It then defends an alternative, process-based view of the metaphysics of attention, on which attention is understood as an activity and not, as psychologists seem to implicitly assume, an accomplishment. The entrenched distinction between accomplishments and activities is shown to shed new light on the metaphysics of attention. It also provides a novel diagnosis of the empirical state of play.

The overwhelmingly predominant view in philosophy sees intending as a mental state, specifically a plan-like state. This paper rejects the predominant view in favor of a starkly opposed novel alternative. After criticizing both the predominant Bratman-esque view of intention, and an alternative view inspired by Michael Thompson, the paper proceeds to set out and defend the idea that acting with an intention to V should be understood disjunctively, as either one’s V-ing intentionally or one’s performing some kind of failed intentional (...) V-ing, where the two disjuncts share no common state of intention. Instructive structural parallels to perceptual disjunctivism are pointed out, and the view is shown, unlike its rivals, to successfully extend to capture both prospective and present intention, thereby unifying the three different guises of intention.

Luiz Henrique Lopes dos Santos, em seu texto sobre "Leibniz e a questão dos futuros contingentes”, argumenta em favor de seu diagnóstico segundo o qual, no fundo, a principal diferença entre as doutrinas de Espinosa e Leibniz reside no fato de que o primeiro, diferentemente do segundo, não sabia lógica. Este texto procura objetar à sua posição, respondendo às críticas do autor à posição de Espinosa quanto à liberdade divina. Procurarei mostrar que, sob o aspecto preciso da articulação aí estabelecida (...) entre a distinção vontade/entendimento e a questão dos possíveis jamais realizados, ela não poderia estar disponível para a metafísica de Espinosa, não por ele ter ignorado um princípio básico da lógica modal, como alega o autor, mas porque ele compreende diferentemente o estatuto ontológico da unidade das coisas individuais e, portanto, dos agentes humanos.

I argue that Descartes' Second Causal Proof of God in the Third Meditation evidences, and commits him to, the belief that time is "strongly discontinuous" -- that is, that there is actually a gap between each consecutive moment of time. Much of my article attempts to reconcile this interpretation, the "received view," with Descartes' statements about time, space, and matter in his other writings, including his correspondence with various philosophers.
