Analyzing the position of two philosophers whose views are recognizably divergent, W. O. Quine and M. Dummett, we intend to support a striking point of agreement between them: the idea that our logical principles constitute our principles about what there is, and therefore, that logic is metaphysics.

Disagreement over what exists is so fundamental that it tends to hinder or even to block dialogue among disputants. The various controversies between believers and atheists, or realists and nominalists, are only two kinds of examples. Interested in contributing to the intelligibility of the debate on ontology, in 1939 Willard van Orman Quine began a series of works which introduces the notion of ontological commitment and proposes an allegedly objective criterion to identify the exact conditions under which a theoretical discourse (...) signals an assumption of existence. I intend to present the concept of ontological commitment and the Quinean criterion, to expose and evaluate some of the many criticisms to which the criterion has subject and to situate it in the context of Quine’s philosophy. As a product of such analyses, I hope to contribute to the discussion on the application and relevance of the notion of ontological commitment. (shrink)

The main objective of this PhD Thesis is to present a method of obtaining strong normalization via natural ordinal, which is applicable to natural deduction systems and typed lambda calculus. The method includes (a) the definition of a numerical assignment that associates each derivation (or lambda term) to a natural number and (b) the proof that this assignment decreases with reductions of maximal formulas (or redex). Besides, because the numerical assignment used coincide with the length of a specific sequence of (...) reduction - the worst reduction sequence - it is the lowest upper bound on the length of reduction sequences. The main commitment of the introduced method is that it is constructive and elementary, produced only through analyzing structural and combinatorial properties of derivations and lambda terms, without appeal to any sophisticated mathematical tool. Together with the exposition of the method, it is presented a comparative study of some articles in the literature that also get strong normalization by means we can identify with the natural ordinal methods. Among them we highlight Howard[1968], which performs an ordinal analysis of Godel’s Dialectica interpretation for intuitionistic first order arithmetic. We reveal a fact about this article not noted by the author himself: a syntactic proof of strong normalization theorem for the system of typified lambda calculus λ⊃ is a consequence of its results. This would be the first strong normalization proof in the literature. (written in Portuguese). (shrink)

É bem conhecida a divergência entre as posições de Gottlob Frege e Bertrand Russell com relação ao tratamento semântico dado a sentenças contendo termos singulares indefinidos, ou seja, termos singulares sem referência ou com referência ambígua, tais como ‘Papai Noel’ ou ‘o atual rei da França’ ou ‘1/0 ’ ou ‘√4’ ou ‘o autor de Principia Mathematica’. Para Frege, as sentenças da linguagem natural que contêm termos indefinidos não formam declarações e portanto não são nem verdadeiras nem falsas. Já para (...) as sentenças da matemática, Frege defende que elas precisam ser corrigidas através da convenção forçada de uma referência não ambígua. Russell, por outro lado, aceita os termos indefinidos e propõe, através de sua teoria das descrições definidas, uma maneira de avaliar as sentenças em que eles ocorrem; e Quine amplia a teoria de Russell para abranger também os nomes com problemas de referência. Na prática da matemática são comuns os termos singulares indefinidos, sem referência, tais como ‘1/0 ’, ou com referência ambígua, tais como ‘√4’. Apesar de não haver uma sistematização rigorosa desta situação entre os matemáticos, há, no entanto, um conjunto de regras convencionais que tradicionalmente costumam ser aplicadas no tratamento matemático dos termos indefinidos. Nossa proposta é tomar a convenção matemática como inspiração e modelo para apresentar uma interpretação semântica formal para as descrições definidas e os nomes e utilizá-la como um argumento que favorece a abordagem de Russell relativamente à de Frege.

Much of the ontology made in the analytic tradition of philosophy nowadays is founded on some of Quine’s proposals. His naturalism and the binding between existence and quantification are respectively two of his very influential metaphilosophical and methodological theses. Nevertheless, many of his specific claims are quite controversial and contemporaneously have few followers. Some of them are: (a) his rejection of higher-order logic; (b) his resistance in accepting the intensionality of ontological commitments; (c) his rejection of first-order modal logic; and (...) (d) his rejection of the distinction between analytic and synthetic statements. I intend to argue that these controversial negative claims are just interconnected consequences of those much more accepted and apparently less harmful metaphilosophical and methodological theses, and that the glue linking all these consequences to its causes is the notion of extensionality.

Divergências sobre o que existe são tão básicas que tendem a dificultar ou até bloquear o diálogo entre os antagonistas. As várias disputas entre crentes e ateus, ou realistas e nominalistas são apenas dois tipos de exemplos. Interessado em contribuir para a inteligibilidade do debate sobre ontologia, em 1939 W. V. Quine iniciou uma série de trabalhos em que apresenta a noção de compromisso ontológico e propõe um critério supostamente objetivo para identificar as condições exatas em que um discurso teórico (...) sinaliza uma suposição de existência. Pretendo apresentar o conceito de compromisso ontológico e o critério quineano, apresentar e avaliar algumas das muitas críticas que o critério recebeu e situá-lo no contexto da filosofia de Quine. Como produto destas análises, espero contribuir para a reflexão sobre a relevância e o lugar filosófico da noção de compromisso ontológico. (shrink)

The purpose of this article is to support the logical incompatibility of the opposing views as a criterion for characterizing disagreements as genuinely metaphysical. That is, I intend to argue that a specific dispute is a metaphysical disagreement only when the conflicting views are governed by different logics. If correct, this criterion would not only help to separate merely verbal from genuine metaphysical debates, but it also would ground an argument against deflationism, guaranteeing the substantiality and relevance of metaphysics. I (...) intend to clarify the criterion, to present its basic foundations and commitments, to give some logical and metaphysical motivations for its adoption and some examples of its application.

Além de responder à pergunta título, pretende-se também apresentar as linhas gerais de um caminho que vem sendo proposto por alguns pensadores sobre de que modo a ciência poderia se modificar de modo a que pudéssemos utilizá-la para resolver nossos principais problemas. Para tanto iniciaremos explicitando o que consideramos as características mais fundamentais da racionalidade científica hegemônica, a saber: o atomismo e o método axiomático. Em seguida, apresentamos alguns conhecidos problemas das ciências, evidenciando suas relações com estas características fundamentais. Tais (...) problemas são tanto epistemológicos e metodológicos, internos ao próprio conhecimento, quanto éticos, relacionados às suas consequências. Em seguida, indicamos como a forte interconexão destes dois tipos de problemas pode ser compreendida quando entendemos a ciência de modo instrumental como uma resposta ao interesse de previsão para manipulação e controle. Por fim, partindo do reconhecimento do caráter contingente e socialmente construído do conhecimento científico, inclusive de suas características fundamentais, respondemos à questão título e apontamos, ainda de modo incipiente, algumas possibilidades de modificações metodológicas que têm sido propostas nos últimos anos. Em especial, apresentamos as que foram rotuladas de complexidade e a transdisciplinaridade, indicando algumas questões e possíveis linhas de pesquisa que estas abordagens suscitam. (shrink)

Parece um fato bastante trivial que quando uma teoria científica se torna obsoleta, por ter sido substituída por outra, isto não tem nenhuma consequência para os objetos técnicos compatíveis com a teoria antiga. Pretendo, neste ensaio, responder à questão bem menos óbvia de por que isto se dá. Como subproduto, apresento uma defesa da teoria da ciência de Thomas Kuhn. Para tanto, inicio mostrando como a teoria de Kuhn foi motivada por considerações sobre a história da ciência. Em seguida, defendo (...) um pressuposto sobre como se dá a relação entre ciência e tecnologia. Continuo, apresentando uma distinção entre conteúdo factual e conceitual na ciência. E. (shrink)

Para que servem o bem, a beleza, o amor? Para que serve a felicidade? Para nada. Para absolutamente nada. A filosofia é tão imprestável quanto as melhores coisas da vida, tão inútil quanto a felicidade, ou uma brincadeira de criança, ou um rabisco na areia deixado por alguém que passou raspando um graveto no chão sem olhar para trás. O impulso que nos move até ela é o mesmo que empurra o alpinista mais um passo para cima, ou os namorados (...) mais um centímetro para perto, ou as crianças para mais um salto na corda. Este pequeno livro não é um tratado de filosofia, mas apenas um convite à alegria de pensar e especular sobre o mundo a nossa volta. Seu autor é um filósofo que não só acha inútil a filosofia, como além disso está aqui em suas horas vagas, divertindo-se com temas sérios, e convidando você a divertir-se também com reflexões filosóficas imprestáveis, porque a utilidade só é valor daquilo que não se basta.

Há alguns anos escrevi um pequeno texto que ilustra uma situação problemática sobre o julgamento de se a vida de uma determinada pessoa fictícia (Bento) foi uma vida feliz ou não. Uso com frequência esse texto em minhas aulas introdutórias, como um recurso didático para explicar o que é a filosofia, qual o seu papel no nosso entendimento do mundo, e também para ilustrar a sua principal dificuldade, que é o caráter aporético das questões filosóficas: elas não admitem soluções unânimes (...) ou incontroversas. Elas sempre exigem escolha e engajamento. O mérito desse texto (que será reproduzido no diálogo abaixo) é que praticamente todos nós, ao o lermos ou ouvirmos, temos uma propensão imediata e irresistível de considerar ou que a vida de Bento foi feliz ou que ela foi infeliz. E nós divergimos sobre isso. Em todas as incontáveis vezes que o apresentei para alguma plateia, jamais as respostas foram unânimes. Sempre houve divergências, o que ilustra bem o caráter aporético da filosofia. Logo que eu soube do ChatGPT e de suas capacidades extraordinárias como sistema de inteligência artificial (IA), resolvi provocá-lo com meu texto. Sua resposta à pergunta sobre a felicidade de Bento foi impressionantemente clara. Talvez a resposta mais clara sobre a questão que já obtive até hoje. Fiquei realmente impressionado, mas também um pouco decepcionado. Porque apesar de fazer uma análise filosófica bastante sofisticada da situação, o ChatGPT recusou-se a fazer uma escolha, a decidir se o personagem teve ou não uma vida feliz. Ele me informou que, como um sistema de IA, ele não tem valores e não faz escolhas. Não gosta nem desgosta, não prefere. E isso me deixou frustrado, porque escolher, preferir, decidir, mesmo quando não temos todas as informações completas é, para mim, não apenas a essência da filosofia, como também a essência de nossa inteligência humana. Como eu queria ver o ChatGPT fazer escolhas, adotei, então, a estratégia de solicitar que ele assumisse um personagem humano, que fingisse ser uma pessoa, e passei a conversar com esta pessoa. Se ele executar bem o papel de uma pessoa, então ele deverá fazer escolhas, pensei. E assim começou esta nossa conversa filosófica sobre a felicidade. (shrink)

A few years ago, I wrote a short text illustrating a problematic situation regarding the judgment of whether a particular fictional person, Bento, led a happy life or not. I frequently use this text in my introductory classes as a didactic resource to explain the nature of philosophy, its role in our understanding of the world, and to demonstrate its main challenge: the aporetic nature of philosophical questions. These questions do not yield unanimous or incontrovertible solutions; they always demand choice (...) and engagement. The merit of this text (which will be reproduced in the dialogue below) lies in the fact that almost everyone, upon reading or hearing it, has an immediate and irresistible inclination to consider Bento's life either happy or unhappy. Opinions tend to differ on this matter. In all the countless times I presented it to an audience, the responses were never unanimous. Disagreements always arose, illustrating the aporetic nature of philosophical questions. As soon as I learned about ChatGPT and its extraordinary capabilities as an artificial intelligence (AI) system, I decided to test it with my text. Its answer to the question of Bento's happiness was remarkably clear; perhaps the most precise response I had ever received. I was genuinely impressed yet somewhat frustrated. Despite providing a rather sophisticated philosophical analysis of the situation, ChatGPT refused to make a choice, to decide whether or not the character led a happy life. It informed me that, as an AI system, it has no values and does not make choices. It neither likes nor dislikes; it does not prefer. This revelation shocked me because choosing, preferring, and deciding, even in the absence of complete information, are, in my view, not only the essence of philosophy but also the essence of human intelligence. Eager to see ChatGPT make choices, I adopted the strategy of asking it to assume a human persona, to pretend to be a person, and I began chatting with this individual. I reasoned that if it played the role of a person convincingly, it must make choices. And so, our philosophical conversation commenced. (shrink)

This collection of essays explores the metaphysical thesis that the living world is not made up of substantial particles or things, as has often been assumed, but is rather constituted by processes. The biological domain is organised as an interdependent hierarchy of processes, which are stabilised and actively maintained at different timescales. Even entities that intuitively appear to be paradigms of things, such as organisms, are actually better understood as processes. Unlike previous attempts to articulate processual views of biology, which (...) have tended to use Alfred North Whitehead’s panpsychist metaphysics as a foundation, this book takes a naturalistic approach to metaphysics. It submits that the main motivations for replacing an ontology of substances with one of processes are to be found in the empirical findings of science. Biology provides compelling reasons for thinking that the living realm is fundamentally dynamic, and that the existence of things is always conditional on the existence of processes. The phenomenon of life cries out for theories that prioritise processes over things, and it suggests that the central explanandum of biology is not change but rather stability, or more precisely, stability attained through constant change. This edited volume brings together philosophers of science and metaphysicians interested in exploring the consequences of a processual philosophy of biology. The contributors draw on an extremely wide range of biological case studies, and employ a process perspective to cast new light on a number of traditional philosophical problems, such as identity, persistence, and individuality.

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

Choices confront us with questions. How we act depends on our answers to those questions. So the way our beliefs guide our choices is not just a function of their informational content, but also depends systematically on the questions those beliefs address. This paper gives a precise account of the interplay between choices, questions and beliefs, and harnesses this account to obtain a principled approach to the problem of deduction. The result is a novel theory of belief-guided action that explains (...) and predicts the decisions of agents who, like ourselves, fail to be logically omniscient: that is, of agents whose beliefs may not be deductively closed, or even consistent.

Supporters of open borders sometimes argue that the state has no pro tanto right to restrict immigration, because such a right would also entail a right to exclude existing citizens for whatever reasons justify excluding immigrants. These arguments can be defeated by suggesting that people have a right to stay put. I present a new form of the exclusion argument against closed borders which escapes this “right to stay put” reply. I do this by describing a kind of exclusion that (...) has not been discussed in depth, which I call “territorial exclusion.” Territorial exclusion is the process according to which the group that wishes to exclude current citizens secedes from the territory in which those citizens reside. I argue that the wrongness of territorial exclusion explains why there is no pro tanto right for a state to exclude immigrants, because otherwise there would be a pro tanto right for the state to kick people out by seceding from the territory they inhabit. Because kicking people out like this is typically wrong, borders cannot be closed. (shrink)

I defend the cosmopolitan instrumentalist theory of secession, according to which a group has a right to secede only if this would promote cosmopolitan justice. I argue that the theory is preferable to other theories of secession because it is an entailment of cosmopolitanism, which is independently attractive, and because, unlike other theories of secession, it allows us to give the answers we want to give in cases like secession of the rich or secession that would make things worse for (...) minorities. I defend the view against the objections that it allows for colonialism and annexation, that it is not a distinct theory, and that it is impractical. (shrink)

This chapter introduces readers to the view that praise is a form of address, or is communicative in the sense of seeking uptake from its target. The proposal that praise is communicative will seem counterintuitive if we take blame to be our paradigm of what it is for a responsibility-response to be communicative. This is because blame is communicative in a manner that intuitively presupposes some normative failure; it involves calling its target to account (or answer) for some wrongdoing. But, (...) the ‘rightdoer’ already properly regarded the relevant reasons in acting praiseworthily. So, there is nothing for which the praiseworthy agent must similarly account or answer for. How then could praise be communicative in sense of seeking uptake from its target? This chapter develops the view that praise is communicative in that it invites the praiseworthy agent to accept credit by co-valuing their action in the evaluative terms supplied by the praiser. This proposal is defended against three objections, namely that it is descriptively inadequate regarding our actual practices, that it is morally mistaken about when we owe others a response, and that it implies redundant communication.

After 50 years of debate, the ethics of aggregation has reached a curious stalemate, with both sides arguing that only their theory treats people as equals. I argue that, on the issue of equality, both sides are wrong. From the premise that “each counts for one,” we cannot derive the conclusion that “more count for more”—or its negation. The familiar arguments from equality to aggregation presuppose more than equality: the Kamm/Scanlon “Balancing Argument” rests on what social choice theorists call “(Positive) (...) Responsiveness,” Kamm’s “Aggregation Argument” assumes that “equal” lives are fungible, and Hsieh et al. have it that spreading goods broadly best approximates equality. In each case, the crucial premise is not equality itself but a further idea that Taurek, I argue, can safely reject. I conclude with a conjecture: there is no theory-neutral argument that settles the question of whether the numbers count. (shrink)

This chapter draws on insights from non-equilibrium thermodynamics to demonstrate the ontological inadequacy of the machine conception of the organism. The thermodynamic character of living systems underlies the importance of metabolism and calls for the adoption of a processual view, exemplified by the Heraclitean metaphor of the stream of life. This alternative conception is explored in its various historical formulations and the extent to which it captures the nature of living systems is examined. Following this, the chapter considers the metaphysical (...) implications of reconceptualizing the organism from complex machine to flowing stream. What do we learn when we reject the mechanical and embrace the processual? Three key lessons for biological ontology are identified. The first is that activity is a necessary condition for existence. The second is that persistence is grounded in the continuous self-maintenance of form. And the third is that order does not entail design. (shrink)

I argue that the phenomenon underlying Bernard Williams’ (1976) “agent-regret” is considerably broader than appreciated by Williams and others. Agent-regret— an anguished response that agents have for harms they have caused, even if faultlessly— I maintain, is a species of a more general response to harms that need not be one’s fault, but which nonetheless impact one’s practical identity in a special way. This broader genus includes as a species what I call “relation-regret”, a pained response to harm caused by (...) a person to whom one is intimately related, as a co-member of a group partly constitutive of one’s practical identity (e.g. one’s family). After providing an account of the moral psychology of relation-regret, I attend to its normative significance, proposing in particular that acceptance of relation-regret provides us with reasons for accepting a novel form of moral luck, namely associative luck: the luck of being vulnerable to responsibility-responses in virtue of one’s attachments to others, despite one’s personal faultlessness.

Deleuze argued that a fundamental mutation in the concept of time occurred in Kant. In antiquity, the concept of time was subordinated to the concept of movement: time was a ‘measure’ of movement. In Kant, this relation is inverted: time is no longer subordinated to movement but assumes an autonomy of its own: time becomes "the pure and empty form" of everything that moves and changes. What is essential in the theory of time is not the distinction between objective ‘clock (...) time’ (or physical time) and the subjective experience of ‘time consciousness,’ since both of them measure movements, whether the movement of extensive objects or intensive states. What is fundamental is rather the relation between time and movement, since time can only assume its own concept when it ceases to be subordinate to movement, whether that movement is objective or subjective. This article examines how Kant inverted the relation between time and movement, and how Deleuze’s own theory of time builds on Kant’s revolution and extends it further. (shrink)

This paper proposes a new account of bounded or minimal doxastic rationality (in the sense of Cherniak 1986), based on the notion that beliefs are answers to questions (à la Yalcin 2018). The core idea is that minimally rational beliefs are linked through thematic connections, rather than entailment relations. Consequently, such beliefs are not deductively closed, but they are closed under parthood (where a part is an entailment that answers a smaller question). And instead of avoiding all inconsistency, minimally rational (...) believers only avoid blatant inconsistencies (where some beliefs are blatantly inconsistent when they contradict one another on a particular question). Rather than cohering into a single overall world view, beliefs are more loosely connected in what is best described as a web of questions. This view of minimally rational belief naturally gives rise to an account of deductive inquiry on which deductive reasoning is a matter of posing new questions. (shrink)

We propose to analyze well-known cases of "imaginative resistance" from the philosophical literature (Gendler, Walton, Weatherson) as involving the inference that particular content should be attributed to either: (i) a character rather than the narrator or, (ii) an unreliable, irrational, opinionated, and/or morally deviant "first person" narrator who was originally perceived to be a typical impersonal, omniscient, "effaced" narrator. We model the latter type of attribution in terms of two independently motivated linguistic mechanisms: accommodation of a discourse referent (Lewis, Stalnaker, (...) Kamp) and 'cautious' updating as a model of non-cooperative information exchange (Eckardt). (shrink)

Philosophers debate about which logical system, if any, is the One True Logic. This involves a disagreement concerning the sufficient conditions that may single out the correct logic among various candidates. This paper discusses whether there are necessary conditions for the correct logic; that is, I discuss whether there are features such that if a logic is correct, then it has those features, although having them might not be sufficient to single out the correct logic. Traditional rationalist arguments suggest that (...) the necessary conditions of thought are necessary and sufficient conditions singling out the correct logical and mathematical theories. In the contemporary debate, Chalmers advocates a view along this line. Jago, analogously, suggests that the necessary conditions for thought—or, as he calls them, our basic epistemic expectations—single out a family of logical and mathematical theories. Warren and Williamson, on the other hand, argue that there are no necessary conditions of thought. I argue that there are necessary conditions for thought, and these are necessary but not sufficient conditions to be the correct logic; indeed, these are features that all logics—correct or incorrect—share. No view we can understand is ruled out by the necessary conditions for thought, but we cannot understand quite any view. Human linguistic and conceptual abilities are genetically constrained, and these constraints are our best guide to the boundaries of logic. Arguing for this, I tackle two dogmas of modern rationalism: namely, the view that the biological constraints of human cognition have no bearing on the boundaries of the epistemic space, and the view that the boundaries of thought coincide with the boundaries of language.

In this paper, I respond to Frank Hofmann’s reply to my (2022) argument against “evidential minimalism” (EM). According to defenders of EM, there is a close connection between evidence and normative reasons for belief: evidence is either itself, or (under certain “minimal” conditions) gives rise to, a normative reason for belief. In my (2022), I argued against EM by showing that there are cases where: (i) S possesses strong evidence E for the truth of p at time t, (ii) all (...) minimal conditions for the normativity of E are met at t, (iii) S doesn’t believe p at t, yet (iv) S isn’t criticizable on account of (i)-(iii) at t. I then appealed to a linking claim connecting criticizability with the existence of normative reasons for belief. Hofmann’s reply invokes a distinction between two different kinds of epistemic criticism: a strong and a weak form. I will argue that Hofmann’s distinction fails to save EM from my argument.

While the contemporary philosophical literature is replete with discussion of the control or freedom required for moral responsibility, only more recently has substantial attention been devoted to the knowledge or awareness required, otherwise called the epistemic condition. This area of inquiry is rapidly expanding, as are the various positions within it. This chapter introduces two major positions: the reasonable expectation view and the quality of will view. The chapter then explores two dimensions of the epistemic condition that serve as fault (...) lines along which these two views diverge. The first dimension concerns different kinds of ignorance. The second concerns what agents can be directly blameworthy for. The chapter closes by sketching a novel approach that incorporates advantages of opposing positions on this topic. (shrink)

Scientific disagreements are an important catalyst for scientific progress. But what happens when scientists disagree amidst times of crisis, when we need quick yet reliable policy guidance? In this paper we provide a normative account for how scientists facing disagreement in the context of ‘fast science’ should respond, and how policy makers should evaluate such disagreement. Starting from an argumentative, pragma-dialectic account of scientific controversies, we argue for the importance of ‘higher-order evidence’ (HOE) and we specify desiderata for scientifically relevant (...) HOE. We use our account to analyze the controversy about the aerosol transmission of COVID-19. (shrink)

Just War Theory (JWT) replaced an older "warrior code," an approach to war that remains poorly understood and dismissively treated in the philosophical literature. This paper builds on recent work on honor to address these deficiencies. By providing a clear, systematic exposition of "Honor War Theory" (HWT), we can make sense of paradigm instances of warrior psychology and behavior, and understand the warrior code as the martial expression of a broader honor-based ethos that conceives of obligation in terms of fair (...) competition for prestige. Far from being a romantic and outmoded approach to war, HWT accounts for current conflicts and predicts moral intuitions that JWT either rejects or cannot comfortably accommodate. So although it is not recommended as a replacement for JWT, there is good reason think that a fully mature, realistic, and yet properly normative theory of war ethics will incorporate a variety of insights from HWT.

It is commonly assumed that blameworthiness is epistemically constrained. If one lacks sufficient epistemic access to the fact that some action harms another, then one cannot be blamed for harming. Acceptance of an epistemic condition for blameworthiness can give rise to a worry, however: could agents ever successfully evade blameworthiness by deliberately stunting their epistemic position? I discuss a particularly worrisome version of such epistemic shirking, in which agents pre-emptively seek to avoid access to potentially morally relevant facts. As Roy (...) Sorensen and Jan Willem Wieland have argued, we seem to be faced with a potentially troubling regress when trying to explain what goes wrong in such situations. I argue that the solution to this so-called Shirker Problem is not to be found in complicated and demanding anti-shirking-principles with universal scope and potentially self-reflexive content. Instead, careful consideration of the necessary motivational make-up of genuine shirkers reveals their ignorance to lack the necessary depth to be exculpatory. Since shirkers by definition react to the possibility of the revelation of morally relevant facts with acts of epistemic self-limitation, they necessarily prove guilty of a form of culpable moral recklessness. Epistemic shirking thus does not pose a worrisome problem for ethical theory. (shrink)

This paper seeks to carve out a distinctive category of conspiracy theorist, and to explore the process of becoming a conspiracy theorist of this sort. Those on whom I focus claim their beliefs trace back to simply trusting their senses and experiences in a commonsensical way, citing what they take to be authoritative firsthand evidence or observations. Certain flat Earthers, anti-vaxxers, and UFO conspiracy theorists, for example, describe their beliefs and evidence this way. I first distinguish these conspiracy theorists by (...) contrasting them with another group that has recently received a lot of attention from the media, philosophers, and academics more broadly. I then dig more deeply into the nature of these conspiracy theorists’ epistemic self-understanding, in order to give an account of the process by which one becomes such a conspiracy theorist. I conclude with some takeaways and implications: first, I explore the implications of my account for whether these conspiracy theorists’ beliefs are rational; then, I argue that my account has practical takeaways about counteracting beliefs in misinformation, since strategies appropriate to this kind of conspiracy theorist may not be the same ones that are appropriate for other kinds.

I consider difficult data involving the interaction of attitudes and conditionals, specifically non-doxastic attitude expressions like 'regret'. I first show that felicitous attitude conditionals in "ignorance contexts", where the relevant person doesn't know the antecedent is true, give rise to a number of difficult problems given widely held assumptions in semantics. I then argue that, even so, we should expect these conditionals to be true and reasonable to utter in ignorance contexts, given certain other kinds of attitude construction that tend (...) to involve free relatives like `whatever'. I then use that observation to explain many of the more puzzling aspects of these conditionals, and to show that we should treat felicitous doxastic attitude conditionals differently from felicitous non-doxastic ones. I leave explaining felicitous doxastic attitude conditionals for future work, but offer constraints on a satisfying explanation of them. (shrink)

This paper argues that praise is governed by a norm of standing, namely the evaluative commitment condition. Even when the target of praise is praiseworthy and known to be so by the praiser, praise can be inappropriate owing to the praiser’s lacking the relevant evaluative commitment. I propose that uncommitted praisers lack the standing to praise in that, owing to their lack of commitment to the relevant value, they have not earned the right to host the co-valuing that is the (...) communicative aim of praise.

This chapter tells the story of how the philosophy of language, as it exists now, grew out of work in the history of analytic philosophy. I pay particular attention to the history of semantics, to debates about propositional content, and to the origins of contemporary pragmatics and speech-act theory. I identify an overarching narrative: Many of the ideas that are now used to understand natural language on its own terms were originally developed not for this purpose, but as methodological tools (...) for diverse philosophical ends.

This paper responds to commentaries by Kaiserman and Magidor, and Hawthorne. The case of the infinite clowns can teach us several things.

Majority rule is often regarded as an important democratic principle. But modern democracies divide voters into districts. So if the majority should rule, which majority should rule? Should it be the popular majority, or an electoral majority (i.e., either the majority of voters in the majority of districts, or the majority of voters in districts that contain the majority of the population)? I argue that majority rule requires rule by the popular majority. This view is not novel and may seem (...) obvious. But it is rarely defended, and often rejected. I defend it by arguing that this view about which majority should rule is best supported by the arguments for why the majority should rule, and best avoids the arbitrary and perverse verdicts of rule by electoral majorities. I close by considering the significant practical implications of the view. The Electoral College is often criticized on the basis that the winner of the popular vote doesn’t always win the election. But all district-based democracies have this feature, so all district-based democracies must be reformed if they are to satisfy the principle of majority rule. (shrink)

In virtue of what do we enjoy episodes of pleasure? According to the phenomenological theory of pleasure, we enjoy pleasures in virtue of having certain kinds of phenomenal experiences. According to the attitude theory of pleasure, we enjoy pleasures in virtue of having a certain kind of pro-attitude. In this chapter, we show that the attitude theory faces a dilemma. The attitude that is relevant to pleasure—the desire, liking, or favoring—is either necessarily co-instantiated with certain phenomenology, or not. If the (...) attitude theorist denies that the relevant attitudes are phenomenologically enriched in this sense, then their theory has the problematic implication that pleasure can come radically apart from phenomenology. This leads to a *problem of hedonic inversion*. If the attitude theorist instead affirms that the relevant attitudes are phenomenologically enriched, then they undermine their main objection to the phenomenological theory of pleasure. This is the so-called *heterogeneity problem*, according to which pleasures do not feel alike. Either way, the attitudinal theorist faces a difficult challenge in their ongoing debate with phenomenological theorists. (shrink)

Zurvanism was an ancient variant of Zoroastrianism. According to Zurvanism, the great powers of good and evil, Ahura Mazda and Angra Mainyu, were the sons of a greater god Zurvan, associated with time. According to Eudemus of Rhodes, some Persian thinkers, presumably Zurvanists, took there to be three great principles underlying the world: light, darkness, and greatest of all time (or perhaps, according to Eudemus, space). This paper explores what metaphysics might underlie these doctrines, and what contemporary options we have (...) for making sense of a metaphysics where time is the ultimate principle. Among the options explored is the option that despite appearance many of the entities of the concrete world are identical to stretches of time, or are somehow aspects of stretches of time; that they include times as parts, or are included in times as parts; that they are somehow properties of time; or hylomorphic compounds of which time is the matter; that the world is somehow a mixture of time, light, and dark; or that somehow the ends or teloi of everyday objects and processes are to be found among good, evil, and time.

This essay defends the controversial and indeed counterintuitive claim that there is a good argument to be made from a Lockean perspective for government action to guarantee access to health care. The essay maintains that this argument is in some regards more robust than the well-known argument in defense of universal health care spelled out by Norman Daniels, which this essay also examines in some detail. Locke's view that government should protect people's lives, property, and freedom–where freedom is understood as (...) independence and self-determination–justifies government action to ensure access to health care, because (roughly), just as individuals cannot protect themselves from crime and foreign invasion, so individuals are unable to provide for their own health care. Defense from disease is as important as defense from crime, and–although this is arguable–government action to guarantee access to health care does not itself undermine freedom. (shrink)

Gottlob Frege and Edmund Husserl are two seemingly different philosophers in their methodology. Both have significantly influenced Western philosophy in that their contributions established fields within philosophy that are of intensive study today. Still, their differences in methodology have, in certain instances, yielded similar or distinct results. Their results ranged from the distinction of sense and reference, objectivity, and the theory of mathematics: specifically, their definition of number. Frege and Husserl have such striking similarities in their theory of sense and (...) reference and related notions that from their apparent correspondence, Frege seems to have acknowledged the coincidences in their theories (Frege & Kluge, 1972) (Hill & Rosado Haddock Intro, 4, & 30-33). That is not to say there are exact parallels between Frege and Husserl and their results, as I will acknowledge their similarities and differences within scale. So, I intend to demonstrate their respective theories and results descriptively to show their likenesses while still recognizing their divergences in scope and methodology. Indirectly, I would also hope to illustrate the ties, in terms of subject matter, of these two philosophers who are historically considered at odds with one another; be it personally, in their schools of philosophy, or methodologically (Hartimo 47-53).

There has recently been a focus on the question of statue removalism. This concerns what to do with public history statues that honour or otherwise celebrate ethically bad historical figures. The specific wrongs of these statues have been understood in terms of derogatory speech, inapt honours, or supporting bad ideologies. In this paper I understand these bad public history statues as history, and identify a distinctive class of public history-specific wrongs. Specifically, public history plays an important identity-shaping role, and bad (...) public history can commit specifically ontic injustice. Understanding bad public history in terms of ontic injustice helps understand not just to address bad public history statues, but also understand the value of public history more broadly. (shrink)
