Certain advocates of the so-called “neo-logicist” movement in the philosophy of mathematics identify themselves as “neo-Fregeans” (e.g., Hale and Wright), presenting an updated and revised version of Frege’s form of logicism. Russell’s form of logicism is scarcely discussed in this literature and, when it is, often dismissed as not really logicism at all (in light of its assumption of axioms of infinity, reducibility and so on). In this paper I have three aims: firstly, to identify more clearly the (...) primary meta-ontological and methodological differences between Russell’s logicism and the more recent forms; secondly, to argue that Russell’s form of logicism offers more elegant and satisfactory solutions to a variety of problems that continue to plague the neo-logicist movement (the bad company objection, the embarrassment of richness objection, worries about a bloated ontology, etc.); thirdly, to argue that neo-Russellian forms of logicism remain viable positions for current philosophers of mathematics.

Antes de entrar cuidadosamente no estudo de cada filósofo, em suas respectivas ordens cronológicas, é necessário dar um panorama geral sobre eles, permitindo, de relance, a localização deles em tempos históricos e a associação de seus nomes com sua teoria ou tema central. l. OS FILÓSOFOS PRÉ-SOCRÁTICOS - No sétimo século antes de Jesus Cristo, nasce o primeiro filósofo grego: Tales de Mileto2 . Ele e os seguintes filósofos jônicos (Anaximandro: Ἀναξίμανδρος: 3 610-546 a.C.) e Anaxímenes: (Άναξιμένης: 586-524 a.C.) tentaram (...) expressar/elucidar o que é a arché, ou constitutivo fundamental do Universo. 4 Também sobressaem as teorias de Pitágoras (Ὁ Πυθαγόρας: 570 a.C.- 495 a.C.), completas de misticismo e Matemática; a de Heráclito (Ἡράκλειτος ὁ Ἐφέσιος: 540-470 a.C.), o filósofo do devir e o de seu oponente, Parmênides (Παρμενίδης: 530-460 a.C.), que elucida a primeira teoria do ser, e para qual é alcunhado como o iniciador da Metafísica. Anaxágoras (Ἀναξαγόρας: 500 a.C.- 428 a.C.) esboça uma teoria sobre o Nous, o espírito divino. Por outro lado, Demócrito (Δημόκριτος: Grécia: 460-370 a.C.) e Empédocles (Ἐμπεδοκλῆς: 490 a.C.-430 a.C.) insistem no materialismo. Em contrapartida, os sofistas (Parmênides, Cálicles (Καλλικλῆς: personagem platônico cuja existência é duvidosa) e Górgias (Γοργίας: 485 a.C.-380 a.C.)) gozam das suas aptidões à dialética, e colocam o relativismo como uma posição filosófica. Sócrates será o inimigo mais temível dessa posição. Este é o começo do movimento filosófico de Atenas, que culmina nos séculos quinto e quarto, tal qual, posteriormente, veremos. 2. O APOGEU GREGO – Sócrates (Σωκράτης: 469 a.C.-399 a.C.), Platão (Πλάτων: 428/427- 348/347 a.C.) e Aristóteles (Ἀριστοτέλης: 384 a.C.-322 a.C.) formam o triunvirato dos grandes filósofos gregos. O primeiro (Sócrates), com seu método "maiêutico" e sua teoria do conceito; o segundo (Platão), com sua teoria das ideias e seu estilo literário (dialogista); e o terceiro (Aristóteles), com a estruturação dos principais ramos filosóficos, como a Lógica, a Metafísica, a Ética, a Psicologia racional e a Política; todos eles elevaram a Filosofia para um posto de primeira ordem. Doravante, todos os filósofos tornam-se credores das contribuições desses gênios. Em certos autores, é clara a influência de Platão ou de Aristóteles. Sendo que, ambos os filósofos, tiveram influência absoluta de Sócrates, uma vez que Platão fora seu discípulo, e Aristóteles discípulo de Platão. A Idade Média, por exemplo, foi toda ela, em sua gênese e desenvolvimento, alicerçada no pensamento e nas ideias platônicas; tal era histórica é caracterizada pela luta em favor de um ou de outro autor; o platonismo tomou precedência nos primeiros séculos do cristianismo; somente após o décimo século Aristóteles foi redescoberto. 3. A FILOSOFIA CRISTÃ MEDIEVAL - Santo Agostinho (354 a.C.-430 a.C.) se destaca, no quinto século, com sua teoria da iluminação e a aplicação da teoria platônica ao Cristianismo. No século XIII, São Tomás de Aquino (1225-1274), sintetiza Aristóteles com o Cristianismo. Os dois autores formam o núcleo da filosofia cristã em seus respectivos séculos. A escolástica teve seu tempo de decadência. Se mencionam, principalmente, dois autores: João Duns Escoto (1266-1308) e Guilherme de Ockham (1285-1347). O primeiro é o "Doutor Sutil ", e o segundo cai em um fideísmo e um nominalismo, para todos os conceitos criticáveis. Em uma segunda parte, tentaremos explicar os respectivos pensamentos dos autores mencionados, e outros que pertencem ao mesmo tempo, antigos e medievais. Naquela época, a Filosofia era puramente realista, aplicada ao mundo e ao homem. Somente na Idade Moderna, a Filosofia assumirá o problema do conhecimento como a base e o começo de todo filosofar. 4. A FILOSOFIA RACIONALISTA (MODERNA) - Na Idade Moderna, sobressai o racionalismo de Descartes (1596-1650) prolongado, então, com Malebranche (1638-1715) (ocasionalismo), Espinosa (1632 -1677) (panteísmo) e Leibniz (1646-1716) (teoria das mônadas). Estamos nos séculos XVII e XVIII. A atenção será focada nas disputas filosóficas da corrente empirista contra a racionalista. 5. A FILOSOFIA EMPIRISTA – O empirismo é florescido, principalmente, na Inglaterra. Francis Bacon (1561-1626), primeiro, e depois Locke (1632-1704) com sua rejeição de ideias inatas, Berkeley (1685-1753) com postura e ideias paradoxais, também idealistas e Hume (1711-1776), com suas famosas críticas contra o princípio da causalidade e o conceito de substância, são os principais autores. 6. KANT E OS IDEALISTAS ALEMÃES - Como a tentativa de sintetizar o racionalismo e empirismo, está a teoria de Kant (1724-1804), no século XVIII. Para o seu gênio seguido pelos três idealistas alemães mais importantes: Fichte (1762-1814) (idealismo subjetivo), Schelling (1775-1854) (idealismo objetivo) e Hegel (1770-1831) (idealismo absoluto). Esses Autores representam o ápice da especulação filosófica. A análise, a profundidade, a complexidade da expressão e o espírito sistemático são as características do gênio alemão idealista. 7. OS FILÓSOFOS DO SÉCULO XIX - Antes de tudo, é necessário mencionar, no século dezenove, aos dois grandes críticos de Hegel, que são Kierkegaard (1813-1855) (precursor do existencialismo) e Marx (1818-1883) (com seu materialismo dialético). O próximo é outro casal: Nietzsche (1844-1900) (teoria do Super-homem) e Schopenhauer (1788-1860) (com seu absoluto pessimismo). Comte (1798-1857) com sua doutrina positivista, completará o quadro desses filósofos. Numa outra oportunidade, vamos desmembrar sobre o pensamento e principais ideias acerca desses autores. 8. OS FILÓSOFOS DO SÉCULO XX - Antes de tudo, há um autor que iluminou a filosofia do século XX: Edmund Husserl (1859-1938), fundador do método fenomenológico. Em seguida, existem dois fluxos que são derivados diretamente de Husserl, a saber, o existencialismo e a axiologia. Dentro da corrente axiológica, estudaremos Scheler (1874-2928). Por outro lado, o existencialismo tem quatro autores principais; dois são alemães: Heidegger (1889-1976) e Jaspers (1883-1969); e os demais são franceses: Sartre (1905-1980) e Marcel (1889-1973). Heidegger insiste em que seu tema tratado em sua filosofia não é a unicidade do homem, mas o ser em geral. Jaspers é famoso por seu conceito de transcendência (Deus). Sartre é um antiteísta sincero, e seu existencialismo é definido como um pensamento que assume todas as consequências da negação de Deus. Em contraste, Gabriel Marcel é um filósofo Católico, que conseguiu uma análise profunda das situações humanas, que aparecem em íntima concordância com as verdades cristãs. Vamos terminar com Russell (1872-1970), autor básico do positivismo lógico.

The author Jacob Roman (Parr) provides commentary and line by line analysis of 218b10 through 223a23 , which is of Aristotle's Physica . -/- written in 2023 .

This paper compares two alternative explanations of pragmatic encroachment on knowledge (i.e., the claim that whether an agent knows that p can depend on pragmatic factors). After reviewing the evidence for such pragmatic encroachment, we ask how it is best explained, assuming it obtains. Several authors have recently argued that the best explanation is provided by a particular account of belief, which we call pragmatic credal reductivism. On this view, what it is for an agent to believe a proposition is (...) for her credence in this proposition to be above a certain threshold, a threshold that varies depending on pragmatic factors. We show that while this account of belief can provide an elegant explanation of pragmatic encroachment on knowledge, it is not alone in doing so, for an alternative account of belief, which we call the reasoning disposition account, can do so as well. And the latter account, we argue, is far more plausible than pragmatic credal reductivism, since it accords far better with a number of claims about belief that are very hard to deny. (shrink)

In the present interview, Jacob Rogozinski elucidates the main concepts and theses he developed in his latest book dedicated to the issue of modern jihadism. On this occasion, he explains his disagreements with other philosophical (Badiou, Baudrillard, Žižek) and anthropological (Girard) accounts of Islamic terrorism. Rogozinski also explains that although jihadism betrays Islam, it nonetheless has everything to do with Islam. Eventually, he describes his own philosophical journey which led him from a phenomenological study of the ego and the (...) flesh to the study of past (witch-hunts, French Reign of Terror) and contemporary (jihadism) terror apparatuses.

Robustness is a common platitude: hypotheses are better supported with evidence generated by multiple techniques that rely on different background assumptions. Robustness has been put to numerous epistemic tasks, including the demarcation of artifacts from real entities, countering the “experimenter’s regress,” and resolving evidential discordance. Despite the frequency of appeals to robustness, the notion itself has received scant critique. Arguments based on robustness can give incorrect conclusions. More worrying is that although robustness may be valuable in ideal evidential circumstances (i.e., (...) when evidence is concordant), often when a variety of evidence is available from multiple techniques, the evidence is discordant. †To contact the author, please write to: Jacob Stegenga, Department of Philosophy, University of California, San Diego, 9500 Gilman Drive, La Jolla, CA 92093; e‐mail: [email protected].

Totalism is the view that one distribution of well-being is better than another just in case the one contains a greater sum of well-being than the other. Many philosophers, following Parfit, reject totalism on the grounds that it entails the repugnant conclusion: that, for any number of excellent lives, there is some number of lives that are barely worth living whose existence would be better. This paper develops a theory of welfare aggregation—the lexical-threshold view—that allows totalism to avoid the repugnant (...) conclusion, as well as its analogues involving suffering populations and the lengths of individual lives. The theory is grounded in some independently plausible views about the structure of well-being, identifies a new source of incommensurability in population ethics, and avoids some of the implausibly extreme consequences of other lexical views, without violating the intuitive separability of lives.

An astonishing volume and diversity of evidence is available for many hypotheses in the biomedical and social sciences. Some of this evidence—usually from randomized controlled trials (RCTs)—is amalgamated by meta-analysis. Despite the ongoing debate regarding whether or not RCTs are the ‘gold-standard’ of evidence, it is usually meta-analysis which is considered the best source of evidence: meta-analysis is thought by many to be the platinum standard of evidence. However, I argue that meta-analysis falls far short of that standard. Different meta-analyses (...) of the same evidence can reach contradictory conclusions. Meta-analysis fails to provide objective grounds for intersubjective assessments of hypotheses because numerous decisions must be made when performing a meta-analysis which allow wide latitude for subjective idiosyncrasies to influence its outcome. I end by suggesting that an older tradition of evidence in medicine—the plurality of reasoning strategies appealed to by the epidemiologist Sir Bradford Hill—is a superior strategy for assessing a large volume and diversity of evidence.

Is well-being the kind of thing that can be summed across individuals? This paper takes a measurement-theoretic approach to answering this question. To make sense of adding well-being, we would need to identify some natural "concatenation" operation on the bearers of well-being that satisfies the axioms of extensive measurement and can therefore be represented by the arithmetic operation of addition. I explore various proposals along these lines, involving the concatenation of segments within lives over time, of entire lives led alongside (...) one another or in sequence, and of evaluatively basic propositions via conjunction. All of these proposals turn out to carry highly controversial commitments about the good. I do not claim that these commitments are unacceptable. But they suggest that we cannot simply take for granted, as many philosophers do, that there is any such thing as the sum of well-being. (shrink)

Matthew Adler's Measuring Social Welfare is an introduction to the social welfare function (SWF) methodology. This essay questions some ideas at the core of the SWF methodology having to do with the relation between the SWF and the measure of well-being. The facts about individual well-being do not single out a particular scale on which well-being must be measured. As with physical quantities, there are multiple scales that can be used to represent the same information about well-being; no one scale (...) is special. Like physical laws, the SWF and its ranking of distributions cannot depend on exactly which of these scales we use. Adler and other theorists in the SWF tradition have used this idea to derive highly restrictive constraints on the shape of the SWF. These constraints rule out seemingly plausible views about distributive justice and population ethics. I argue, however, that these constraints stem from a simple but instructive mistake. The SWF should not be applied to vectors of numbers such as 1 and 2, but rather to vectors of dimensioned quantities such as 1 util and 2 utils. This seemingly pedantic suggestion turns out to have far-reaching consequences. Unlike the orthodox SWF approach, treating welfare levels as dimensioned quantities lets us distinguish between real changes in well-being and mere changes in the unit of measurement. It does this without making the SWF depend on the scale on which welfare is measured, and in a way that avoids the restrictive constraints on the shape of the SWF. (shrink)

Nietzsche offers a positive epistemology, and those who interpret him as a skeptic or a mere pragmatist are mistaken. Instead he supports what he calls per- spectivism. This is a familiar take on Nietzsche, as perspectivism has been analyzed by many previous interpreters. The present paper presents a sketch of the textually best supported and logically most consistent treatment of perspectivism as a first- order epistemic theory. What’s original in the present paper is an argument that Nietzsche also offers a (...) second-order methodological perspectivism aimed at enhancing understanding, an epistemic state distinct from knowledge. Just as Descartes considers and rejects radical skepticism while at the same time adopting methodological skepticism, one could consistently reject perspectivism as a theory of knowledge while accepting it as contributing to our understanding. It is argued that Nietzsche’s perspectivism is in fact two-tiered: knowledge is perspectival because truth itself is, and in addition there is a methodological perspectivism in which distinct ways of knowing are utilized to produce understanding. A review of the manner in which understanding is conceptualized in contemporary epistemology and philosophy of science serves to illuminate how Nietzsche was tackling these ideas. (shrink)

This paper presents a new kind of problem in the ethics of distribution. The problem takes the form of several “calibration dilemmas,” in which intuitively reasonable aversion to small-stakes inequalities requires leading theories of distribution to recommend intuitively unreasonable aversion to large-stakes inequalities. We first lay out a series of such dilemmas for prioritarian theories. We then consider a widely endorsed family of egalitarian views and show that they are subject to even more forceful calibration dilemmas than prioritarian theories. Finally, (...) we show that our results challenge common utilitarian accounts of the badness of inequalities in resources. (shrink)

A stereotype is a belief or claim that a group of people has a particular feature. Stereotypes are expressed by sentences that have the form of generic statements, like “Canadians are nice.” Recent work on generics lends new life to understanding generics as statements involving probabilities. I argue that generics (and thus sentences expressing stereotypes) can take one of several forms involving conditional probabilities, and these probabilities have what I call a naturalness requirement. This is the natural probability theory of (...) stereotypes. Each of the two components of the theory entails a family of fallacies that contributes to the spurious reinforcement of stereotypes: inferential slippage within and between the different generic forms, and inferential slippage from facts about frequencies of group traits to beliefs about natural propensities or dispositions of groups. Empirical research suggests that we often commit these fallacies. Moreover, this theory can referee a vitriolic debate between some psychologists, who hold that stereotypes are always false and stereotyping is always wrong, and other psychologists, who hold that stereotypes are often accurate and stereotyping is often reasonable.

Published in 1903, this book was the first comprehensive treatise on the logical foundations of mathematics written in English. It sets forth, as far as possible without mathematical and logical symbolism, the grounds in favour of the view that mathematics and logic are identical. It proposes simply that what is commonly called mathematics are merely later deductions from logical premises. It provided the thesis for which _Principia Mathematica_ provided the detailed proof, and introduced the work of Frege to a wider (...) audience. In addition to the new introduction by John Slater, this edition contains Russell's introduction to the 1937 edition in which he defends his position against his formalist and intuitionist critics.

The phenomenon of disagreement has recently been brought into focus by the debate between contextualists and relativist invariantists about epistemic expressions such as ‘might’, ‘probably’, indicative conditionals, and the deontic ‘ought’. Against the orthodox contextualist view, it has been argued that an invariantist account can better explain apparent disagreements across contexts by appeal to the incompatibility of the propositions expressed in those contexts. This paper introduces an important and underappreciated phenomenon associated with epistemic expressions — a phenomenon that we call (...) reversibility. We argue that the invariantist account of disagreement is incompatible with reversibility, and we go on to show that reversible sentences cast doubt on the putative data about disagreement, even without assuming invariantism. Our argument therefore undermines much of the motivation for invariantism, and provides a new source for constraints on the proper explanation of purported data about disagreement. (shrink)

This paper is about the role of interpersonal comparisons in Harsanyi's aggregation theorem. Harsanyi interpreted his theorem to show that a broadly utilitarian theory of distribution must be true even if there are no interpersonal comparisons of well-being. How is this possible? The orthodox view is that it is not. Some argue that the interpersonal comparability of well-being is hidden in Harsanyi's premises. Others argue that it is a surprising conclusion of Harsanyi's theorem, which is not presupposed by any one (...) of the premises. I argue instead that Harsanyi was right: his theorem and its weighted-utilitarian conclusion do not require interpersonal comparisons of well-being. The key to making sense of this possibility is to treat Harsanyi's weights as dimensional constants rather than dimensionless numbers. (shrink)

Lara Buchak argues for a version of rank-weighted utilitarianism that assigns greater weight to the interests of the worse off. She argues that our distributive principles should be derived from the preferences of rational individuals behind a veil of ignorance, who ought to be risk averse. I argue that Buchak’s appeal to the veil of ignorance leads to a particular way of extending rank-weighted utilitarianism to the evaluation of uncertain prospects. This method recommends choices that violate the unanimous preferences of (...) rational individuals and choices that guarantee worse distributions. These results, I suggest, undermine Buchak’s argument for rank-weighted utilitarianism. (shrink)

This article presents Paul Ricœur’s hermeneutic of the productive imagination as a methodological tool for understanding the innovative social function of texts that in exceeding their semantic meaning, iconically augment reality. Through the reasoning of Rastafari elder Mortimo Planno’s unpublished text, Rastafarian: The Earth’s Most Strangest Man, and the religious and biblical signification from the music of his most famous postulate, Bob Marley, this article applies Paul Ricœur’s schema of the religious productive imagination to conceptualize the metaphoric transfer from text (...) to life of verbal and iconic images of Rastafari’s hermeneutic of word, sound and power. This transformation is accomplished through what Ricœur terms the phenomenology of the iconic augmentation of reality. Understanding this semantic innovation is critical to understanding the capacity of the religious imagination to transform reality as a proclamation of hope in the midst of despair. (shrink)

With the advent of the digital age and new mediums of communication, it is becoming increasingly important for those interested in the interpretation of religious text to look beyond traditional ideas of text and textuality to find the sacred in unlikely places. Paul Ricoeur’s phenomenological reorientation of classical hermeneutics from romanticized notions of authorial intent and psychological divinations to a serious engagement with the “science of the text” is a hermeneutical tool that opens up an important dialogue between the interpreter, (...) the world of the text, and the contemporary world in front of the text. This article examines three significant insights that Paul Ricoeur contributes to our expanding understanding of text. First under scrutiny will be Ricoeur’s de-regionalization of classic hermeneutics culminating in his understanding of Dasein (Being) as “being-in-the-world,” allowing mean-ing to transcend the physical boundaries of the text. Next, Ricoeur’s three-fold under-standing of traditionality/Traditions/tradition as the “chain of interpretations” through which religious language transcends the tem-poral boundary of historicity will be explored. The final section will focus on Ricoeur’s understanding of the productive imagination and metaphoric truth as the under-appreciated yet key insight around which Ricoeur’s philosophical investigation into the metaphoric transfer from text to life revolves.

I present a new argument for the repugnant conclusion. The core of the argument is a risky, intrapersonal analogue of the mere addition paradox. The argument is important for three reasons. First, some solutions to Parfit’s original puzzle do not obviously generalize to the intrapersonal puzzle in a plausible way. Second, it raises independently important questions about how to make decisions under uncertainty for the sake of people whose existence might depend on what we do. And, third, it suggests various (...) difficulties for leading views about the value of a person’s life compared to her nonexistence. (shrink)

According to what Birch (2022) calls the theory-heavy approach to investigating nonhuman-animal consciousness, we select one of the well-developed theories of consciousness currently debated within contemporary cognitive science and investigate whether animals exhibit the neural structures or cognitive abilities posited by that theory as sufficient for consciousness. Birch argues, however, that this approach is in general problematic because it faces what he dubs the dilemma of demandingness—roughly, that we cannot use theories that are based on the human case to assess (...) consciousness in nonhuman animals and vice versa. We argue here that, though this dilemma may problematize the application of many current accounts of consciousness to nonhuman animals, it does not challenge the use of standard versions of the higher-order thought theory (“HOTT”) of consciousness, according to which a creature is in a conscious mental state just in case it is aware of being in that state via a suitable higher-order thought (“HOT”). We show this in two ways. First, we argue that, unlike many extant theories of consciousness, HOTT is typically motivated by a commonsense, and more importantly, neutral condition on consciousness that applies to humans and animals alike. Second, we offer new empirical and theoretical reasons to think that many nonhuman animals possess the relevant HOTs necessary for consciousness. Considering these issues not only reveals the explanatory power of HOTT and some of its advantages over rival accounts, but also enables us to further extend and clarify the theory. (shrink)

Robustness arguments hold that hypotheses are more likely to be true when they are confirmed by diverse kinds of evidence. Robustness arguments require the confirming evidence to be independent. We identify two kinds of independence appealed to in robustness arguments: ontic independence —when the multiple lines of evidence depend on different materials, assumptions, or theories—and probabilistic independence. Many assume that OI is sufficient for a robustness argument to be warranted. However, we argue that, as typically construed, OI is not a (...) sufficient independence condition for warranting robustness arguments. We show that OI evidence can collectively confirm a hypothesis to a lower degree than individual lines of evidence, contrary to the standard assumption undergirding usual robustness arguments. We employ Bayesian networks to represent the ideal empirical scenario for a robustness argument and a variety of ways in which empirical scenarios can fall short of this ideal. (shrink)

The standard view of "believes" and other propositional attitude verbs is that such verbs express relations between agents and propositions. A sentence of the form “S believes that p” is true just in case S stands in the belief-relation to the proposition that p; this proposition is the referent of the complement clause "that p." On this view, we would expect the clausal complements of propositional attitude verbs to be freely intersubstitutable with their corresponding proposition descriptions—e.g., "the proposition that p"—as (...) they are in the case of "believes." In many cases, however, intersubstitution of that-clauses and proposition descriptions fails to preserve truth value or even grammaticality. These substitution failures lead some philosophers to reject the standard view of propositional attitude reports. Others conclude that propositional attitude verbs are systematically ambiguous. I reject both these views. On my view, the that-clause complements of propositional attitude verbs denote propositions, but proposition descriptions do not. (shrink)

The Rachels–Temkin spectrum arguments against the transitivity of better than involve good or bad experiences, lives, or outcomes that vary along multiple dimensions—e.g., duration and intensity of pleasure or pain. This paper presents variations on these arguments involving combinations of good and bad experiences, which have even more radical implications than the violation of transitivity. These variations force opponents of transitivity to conclude that something good is worse than something that isn’t good, on pain of rejecting the good altogether. That (...) is impossible, so we must reject the spectrum arguments. (shrink)

The value-free ideal for science holds that values should not influence the core features of scientific reasoning. We defend the difference-to-inference model of value-permeation, which holds that value-permeation in science is problematic when values make a difference to the inferences made about a hypothesis. This view of value-permeation is superior to existing views, and it suggests a corresponding maxim—namely, that scientists should strive to eliminate differences to inference. This maxim is the basis of a novel value-free ideal for science. -/- (...) . (shrink)

I defend the view that a reason for someone to do something is just a reason why she ought to do it. This simple view has been thought incompatible with the existence of reasons to do things that we may refrain from doing or even ought not to do. For it is widely assumed that there are reasons why we ought to do something only if we ought to do it. I present several counterexamples to this principle and reject some (...) ways of understanding "ought" so that the principle is compatible with my examples. I conclude with a hypothesis for when and why the principle should be expected to fail. (shrink)

In 1655 La Peyrère was the first to substantially argue for and popularize polygenism—the view that God created multiple original human mating pairs in separate acts of creation with numerous created before Adam. Positing or rejecting polygenism has been central to modern theorizing about human types and origins. Prominent recent interpreters have maintained that La Peyrère’s polygenism does not imply a hierarchy of human types. This paper reconstructs La Peyrère’s account and, in opposition to the dominant view, argues that his (...) polygenism produces a human species hierarchy. The Adamite species is superior to the Pre-Adamite species in virtue of its material composition, mode of creation, and form. The upshot is that La Peyrère’s theological system posits a proto-racialist conception of human types. (shrink)

ABSTRACT Sometimes it seems that an existing bearer of value should be preserved even though it could be destroyed and replaced with something of equal or greater value. How can this conservative intuition be explained and justified? This paper distinguishes three answers, which I call existential, attitudinal, and object-affecting conservatism. I raise some problems for existential and attitudinal conservatism, and suggest how they can be solved by object-affecting conservatism.

Building on Christopher Peacocke’s account of analog perceptual contentand my own account of analog perceptual vehicles, I defend three claims: that theperception of magnitudes often has analog contents; that the perception of magni-tudes often has analog vehicles; and that the first claim is true in virtue of the second—that is, the analog vehicles help to ground the analog contents.

According to Rosenthal's higher-order thought (HOT) theory of consciousness, one is in a conscious mental state if and only if one is aware of oneself as being in that state via a suitable HOT. Several critics have argued that the possibility of so-called targetless HOTs—that is, HOTs that represent one as being in a state that does not exist—undermines the theory. Recently, Wilberg (2010) has argued that HOT theory can offer a straightforward account of such cases: since consciousness is a (...) property of mental state tokens, and since there are no states to exhibit consciousness, one is not in conscious states in virtue of targetless HOTs. In this paper, I argue that Wilberg's account is problematic and that Rosenthal's version of HOT theory, according to which a suitable HOT is both necessary and sufficient for consciousness, is to be preferred to Wilberg's account. I then argue that Rosenthal's account can comfortably accommodate targetless HOTs because consciousness is best understood as a property of individuals, not a property of states. (shrink)

The animal agriculture industry causes animals a tremendous amount of pain and suffering. Many ethical vegans argue that we therefore have an obligation to abstain from animal products in order to reduce this suffering. But this argument faces a challenge: thanks to the size and structure of the animal agriculture industry, any individual’s dietary choices are overwhelmingly unlikely to make a difference. In this paper, we criticize common replies to this challenge and develop an alternative argument for ethical veganism. Specifically, (...) we argue that individuals should abstain from animal products because vegans, as a group, successfully reduce animal suffering, and individuals are obligated to participate in, rather than free ride on, this collective endeavor. Or, at the very least, individuals have strong reasons to purchase fewer inhumanely raised animal products—even if they are not obligated to go vegan per se. (shrink)

This paper develops and explores a new framework for theorizing about the measurement and aggregation of well-being. It is a qualitative variation on the framework of social welfare functionals developed by Amartya Sen. In Sen’s framework, a social or overall betterness ordering is assigned to each profile of real-valued utility functions. In the qualitative framework developed here, numerical utilities are replaced by the properties they are supposed to represent. This makes it possible to characterize the measurability and interpersonal comparability of (...) well-being directly, without the use of invariance conditions, and to distinguish between real changes in well-being and merely representational changes in the unit of measurement. The qualitative framework is shown to have important implications for a range of issues in axiology and social choice theory, including the characterization of welfarism, axiomatic derivations of utilitarianism, the meaningfulness of prioritarianism, the informational requirements of variable-population ethics, the impossibility theorems of Arrow and others, and the metaphysics of value.

Many economists and philosophers assume that status quo bias is necessarily irrational. I argue that, in some cases, status quo bias is fully rational. I discuss the rationality of status quo bias on both subjective and objective theories of the rationality of preferences. I argue that subjective theories cannot plausibly condemn this bias as irrational. I then discuss one kind of objective theory, which holds that a conservative bias toward existing things of value is rational. This account can fruitfully explain (...) some compelling aspects of common sense morality, and it may justify status quo bias. (shrink)

According to asymmetric comparativism, it is worse for a person to exist with a miserable life than not to exist, but it is not better for a person to exist with a happy life than not to exist. My aim in this paper is to explain how asymmetric comparativism could possibly be true. My account of asymmetric comparativism begins with a different asymmetry, regarding the (dis)value of early death. I offer an account of this early death asymmetry, appealing to the (...) idea of conditional goods, and generalize it to explain how asymmetric comparativism could possibly be true. I also address the objection that asymmetric comparativism has unacceptably antinatalist implications. (shrink)

Aristotle is said to have held that any kind of actual infinity is impossible. I argue that he was a finitist (or "potentialist") about _magnitude_, but not about _plurality_. He did not deny that there are, or can be, infinitely many things in actuality. If this is right, then it has implications for Aristotle's views about the metaphysics of parts and points.

The presence of symmetries in physical theories implies a pernicious form of underdetermination. In order to avoid this theoretical vice, philosophers often espouse a principle called Leibniz Equivalence, which states that symmetry-related models represent the same state of affairs. Moreover, philosophers have claimed that the existence of non-trivial symmetries motivates us to accept the Invariance Principle, which states that quantities that vary under a theory’s symmetries aren’t physically real. Leibniz Equivalence and the Invariance Principle are often seen as part of (...) the same package. I argue that this is a mistake: Leibniz Equivalence and the Invariance Principle are orthogonal to each other. This means that it is possible to hold that symmetry-related models represent the same state of affairs whilst having a realist attitude towards variant quantities. Various arguments have been presented in favour of the Invariance Principle: a rejection of the Invariance Principle is inter alia supposed to cause indeterminism, undetectability or failure of reference. I respond that these arguments at best support Leibniz Equivalence. (shrink)

People with the kind of preferences that give rise to the St. Petersburg paradox are problematic---but not because there is anything wrong with infinite utilities. Rather, such people cannot assign the St. Petersburg gamble any value that any kind of outcome could possibly have. Their preferences also violate an infinitary generalization of Savage's Sure Thing Principle, which we call the *Countable Sure Thing Principle*, as well as an infinitary generalization of von Neumann and Morgenstern's Independence axiom, which we call *Countable (...) Independence*. In violating these principles, they display foibles like those of people who deviate from standard expected utility theory in more mundane cases: they choose dominated strategies, pay to avoid information, and reject expert advice. We precisely characterize the preference relations that satisfy Countable Independence in several equivalent ways: a structural constraint on preferences, a representation theorem, and the principle we began with, that every prospect has a value that some outcome could have.

Amalgamating evidence of different kinds for the same hypothesis into an overall confirmation is analogous, I argue, to amalgamating individuals’ preferences into a group preference. The latter faces well-known impossibility theorems, most famously “Arrow’s Theorem”. Once the analogy between amalgamating evidence and amalgamating preferences is tight, it is obvious that amalgamating evidence might face a theorem similar to Arrow’s. I prove that this is so, and end by discussing the plausibility of the axioms required for the theorem.

Evidence hierarchies are widely used to assess evidence in systematic reviews of medical studies. I give several arguments against the use of evidence hierarchies. The problems with evidence hierarchies are numerous, and include methodological shortcomings, philosophical problems, and formal constraints. I argue that medical science should not employ evidence hierarchies, including even the latest and most-sophisticated of such hierarchies.

This is the lightly revised text of my commentary/response to David Carr’s keynote address, “Phenomenology of Crisis,” at the 2024 meeting of the Husserl Circle.

A platitude that took hold with Kuhn is that there can be several equally good ways of balancing theoretical virtues for theory choice. Okasha recently modelled theory choice using technical apparatus from the domain of social choice: famously, Arrow showed that no method of social choice can jointly satisfy four desiderata, and each of the desiderata in social choice has an analogue in theory choice. Okasha suggested that one can avoid the Arrow analogue for theory choice by employing a strategy (...) used by Sen in social choice, namely, to enhance the information made available to the choice algorithms. I argue here that, despite Okasha’s claims to the contrary, the information-enhancing strategy is not compelling in the domain of theory choice. (shrink)

How should we choose between uncertain prospects in which different possible people might exist at different levels of wellbeing? Alex Voorhoeve and Marc Fleurbaey offer an egalitarian answer to this question. I give some reasons to reject their answer and then sketch an alternative, which I call person-affecting prioritarianism.

Measuring the effectiveness of medical interventions faces three epistemological challenges: the choice of good measuring instruments, the use of appropriate analytic measures, and the use of a reliable method of extrapolating measures from an experimental context to a more general context. In practice each of these challenges contributes to overestimating the effectiveness of medical interventions. These challenges suggest the need for corrective normative principles. The instruments employed in clinical research should measure patient-relevant and disease-specific parameters, and should not be sensitive (...) to parameters that are only indirectly relevant. Effectiveness always should be measured and reported in absolute terms (using measures such as 'absolute risk reduction'), and only sometimes should effectiveness also be measured and reported in relative terms (using measures such as 'relative risk reduction')-employment of relative measures promotes an informal fallacy akin to the base-rate fallacy, which can be exploited to exaggerate claims of effectiveness. Finally, extrapolating from research settings to clinical settings should more rigorously take into account possible ways in which the intervention in question can fail to be effective in a target population.

Consensus conferences are social techniques which involve bringing together a group of scientific experts, and sometimes also non-experts, in order to increase the public role in science and related policy, to amalgamate diverse and often contradictory evidence for a hypothesis of interest, and to achieve scientific consensus or at least the appearance of consensus among scientists. For consensus conferences that set out to amalgamate evidence, I propose three desiderata: Inclusivity, Constraint, and Evidential Complexity. Two examples suggest that consensus conferences can (...) readily satisfy Inclusivity and Evidential Complexity, but consensus conferences do not as easily satisfy Constraint. I end by discussing the relation between social inclusivity and the three desiderata. (shrink)

Drug regulation is fraught with inductive risk. Regulators must make a prediction about whether or not an experimental pharmaceutical will be effective and relatively safe when used by typical patients, and such predictions are based on a complex, indeterminate, and incomplete evidential basis. Such inductive risk has important practical consequences. If regulators reject an experimental drug when it in fact has a favourable benefit/harm profile, then a valuable intervention is denied to the public and a company’s material interests are needlessly (...) thwarted. Conversely, if regulators approve an experimental drug when it in fact has an unfavourable benefit/harm profile, then resources are wasted, people are needlessly harmed, and other potentially more effective treatments are underutilized. Given that such regulatory decisions have these practical consequences, non-epistemic values about the relative importance of these consequences impact the way such regulatory decisions are made (similar to the analysis of laboratory studies on the toxic effects of dioxins presented in Douglas [2000]). To balance the competing demands of the pertinent non-epistemic values, regulators must perform what I call an “inductive risk calculus.” At least in the American context this inductive risk calculus is not well-managed.

As we build increasingly intelligent machines, we confront difficult questions about how to specify their objectives. One approach, which we call human-centered, tasks the machine with the objective of learning and satisfying human objectives by observing our behavior. This paper considers how human-centered AI should conceive the humans it is trying to help. We argue that an Aristotelian model of human agency has certain advantages over the currently dominant theory drawn from economics.

Medicalisation is a social phenomenon in which conditions that were once under legal, religious, personal or other jurisdictions are brought into the domain of medical authority. Low sexual desire in females has been medicalised, pathologised as a disease, and intervened upon with a range of pharmaceuticals. There are two polarised positions on the medicalisation of low female sexual desire: I call these the mainstream view and the critical view. I assess the central arguments for both positions. Dividing the two positions (...) are opposing models of the aetiology of low female sexual desire. I conclude by suggesting that the balance of arguments supports a modest defence of the critical view regarding the medicalisation of low female sexual desire. (shrink)

In “On what matters: Personal identity as a phenomenological problem” (2020), Steven Crowell engages a number of contemporary interpretations of Husserl’s account of the person and personal identity by noting that they lack a phenomenological elucidation of the self as commitment. In this article, in response to Crowell, I aim to show that such an account of the self as commitment can be drawn from Husserl’s work by looking more closely at his descriptions from the time of Ideas and after (...) of the self as ego or I and egoic experience as attentive experience. I specifically aim to sketch the beginning of a response to three questions I take Crowell to be posing to a Husserlian account of the person and personal identity: (1) What more than pre-reflective self-awareness can be attributed to the self on phenomenological grounds so that we can understand, phenomenologically speaking, how selves become persons? (2) How can what characterizes the self in addition to pre-reflective self-awareness be discerned in both our commitment to truth and our feeling bound by love and other emotive commitments that cannot be fully rationally justified, which Husserl acknowledges are both sources of personal self-constitution? And (3), do all selves become persons? In the paper I elaborate how my answers to the first two questions turn on the self not just being self-aware but active in a particular sense. And to begin to address the third question, I suggest that while any form of wakeful conscious experience is both self-aware and active, this activity of the self makes a difference for those who are socio-historically embedded in the way we are. Specifically, on the proposed Husserlian account, selves that are socio-historically embedded become persons in and through their active relating to what they attentively experience. In concluding, I indicate how this Husserlian account might compare to Crowell’s claim that “self-identity (ipseity) is not mere logical identity (A=A) but a normative achievement […] which makes a ‘personal’ kind of identity possible” (2020).

This is a contribution to a Book symposium on The Limits of Free Will: Selected Essays by Paul Russell. Russell provides replies to three critics of The Limits of Free Will. The first reply is to Robert Wallace and focuses on the question of whether there is a conflict between the core compatibilist and pessimist components of the "critical compatibilist" position that Russell has advanced. The second reply is to Angela Smith's discussion of the "narrow" interpretation of (...) moral responsibility responsibility (as defended by R. Jay Wallace) and how best to respond to it. The third and last reply is concerned with Christopher Bennett's criticism of Russell's views concerning "motivational scepticism" and the possibility of pure practical reasons. (shrink)

Representationalism holds that a perceptual experience's qualitative character is identical with certain of its representational properties. To date, most representationalists endorse atomistic theories of perceptual content, according to which an experience's content, and thus character, does not depend on its relations to other experiences. David Rosenthal, by contrast, proposes a view that is naturally construed as a version of representationalism on which experiences’ relations to one another determine their contents and characters. I offer here a new defense of this holistic (...) representationalism, arguing that some objections to atomistic views are best interpreted as supporting it. (shrink)
