Many philosophers have appealed to the PSR in arguments for a being that exists a se, a being whose explanation is in itself. But what does it mean, exactly, for something to have its explanation ‘in itself’? Contemporary philosophers have said next to nothing about this, relying instead on phrases plucked from the accounts of various historical figures. In this article, I analyse five such accounts – those of Anselm, Aquinas, Descartes, Spinoza, and Leibniz – and argue that none are (...) satisfactory. Should we abandon or restrict the PSR, then? I think that would be hasty, for many reasons. I therefore consider the prospects of explaining everything, including God, given the constraints of certain features of good explanations, and conclude with several observations about future approaches.

Would the existence of extraterrestrial intelligent life conflict in any way with Christian belief? We identify six areas of potential conflict. If there be no conflict in any of these areas—and we argue ultimately there is not—we are confident in declaring that there is no conflict, period. This conclusion underwrites the integrity of theological explorations into the existence of ETI, which has become a topic of increasing interest among theologians in recent years.

I explore the view that the imago Dei is essential to us as humans but accidental to us as persons. To image God is to resemble God, and resemblance comes in degrees. This has the straightforward—and perhaps disturbing—implication that we can be more or less human, and possibly cease to be human entirely. Hence, I call it the spectrum view. I argue that the spectrum view is complementary to the Biblical data, helps explain the empirical reality of horrendous evil, and (...) offers an elegant rapprochement between the traditional view of hell and its rivals.

I argue that Social Trinitarians can and should conceive of God as a group person. They can by drawing on recent theories of group agency realism that show how groups can be not just agents but persons distinct from their members – albeit, I argue, persons of a different kind. They should because the resultant novel view of the Trinity – that God is three ‘intrinsicist’ persons in one ‘functional’ person – is theologically sound, effectively counters the most trenchant criticisms (...) of Social Trinitarianism, and enjoys independent theological support from the biblical notion of ‘corporate personality’.

Linda Zagzebski’s book on epistemic authority is an impressive and stimulating treatment of an important topic. 1 I admire the way she manages to combine imagination, originality and argumentative control. Her work has the further considerable merit of bringing analytic thinking and abstract theory to bear upon areas of concrete human concern, such as the attitudes one should have towards moral and religious authority. The book is stimulating in a way good philosophy should be -- provoking both disagreement and emulation. (...) I agree with much of what she says, and have been instructed by it, but it will be of more interest and relevance here if I concentrate upon areas of disagreement. Perhaps they are better seen as areas, at least some of them, where her emphases suggest a position that seems to me untenable, but that she may not really intend. In that event, I will be happy to have provoked a clarification or the dispelling of my misunderstanding. My focus will be upon problems in her account of communal authority and autonomy, especially with respect to religious and political authority. Here my worry is that she places too much trust in trust and not enough in what I call selective mistrust. (shrink)

The question I wish to explore is this: Does idealism conflict with common sense? Unfortunately, the answer I give may seem like a rather banal one: It depends. What do we mean by ‘idealism’ and ‘common sense?’ I distinguish three main varieties of idealism: absolute idealism, Berkeleyan idealism, and dualistic idealism. After clarifying what is meant by common sense, I consider whether our three idealisms run afoul of it. The first does, but the latter two don’t. I conclude that while (...) Moore’s famous common sense critique is sound against external world skepticism, against Berkeleyan idealism and dualist idealism it is unavailing. (shrink)

A focussed issue of The Reasoner on the topic of 'Infinitary Reasoning'. Owen Griffiths and A.C. Paseau were the guest editors.

What are we to make of the cultural nonconformity of hardcore/punks? Is there any ethical value in the pursuit of cultural nonconformity? Distinct moral justifications can be teased from the lyrics of the hardcore/punk bands that we have grown up with and still love. The best explanation of what makes cultural nonconformity morally valuable, we believe, comes from John Stuart Mill: that it opens up new cultural space to oneself and to others, permitting "new and original experiments of living.".

Visual imagery is a form of sensory imagination, involving subjective experiences typically described as similar to perception, but which occur in the absence of corresponding external stimuli. We used the Activation Likelihood Estimation algorithm (ALE) to identify regions consistently activated by visual imagery across 40 neuroimaging studies, the first such meta-analysis. We also employed a recently developed multi-modal parcellation of the human brain to attribute stereotactic co-ordinates to one of 180 anatomical regions, the first time this approach has been combined (...) with the ALE algorithm. We identified a total 634 foci, based on measurements from 464 participants. Our overall comparison identified activation in the superior parietal lobule, particularly in the left hemisphere, consistent with the proposed ‘top-down’ role for this brain region in imagery. Inferior premotor areas and the inferior frontal sulcus were reliably activated, a finding consistent with the prominent semantic demands made by many visual imagery tasks. We observed bilateral activation in several areas associated with the integration of eye movements and visual information, including the supplementary and cingulate eye fields (SCEFs) and the frontal eye fields (FEFs), suggesting that enactive processes are important in visual imagery. V1 was typically activated during visual imagery, even when participants have their eyes closed, consistent with influential depictive theories of visual imagery. Temporal lobe activation was restricted to area PH and regions of the fusiform gyrus, adjacent to the fusiform face complex (FFC). These results provide a secure foundation for future work to characterise in greater detail the functional contributions of specific areas to visual imagery. (shrink)

Background If trials of therapeutic interventions are to serve society's interests, they must be of high methodological quality and must satisfy moral commitments to human subjects. The authors set out to develop a clinical - trials compendium in which standards for the ethical treatment of human subjects are integrated with standards for research methods. Methods The authors rank-ordered the world's nations and chose the 31 with >700 active trials as of 24 July 2008. Governmental and other authoritative entities of the (...) 31 countries were searched, and 1004 English-language documents containing ethical and/or methodological standards for clinical trials were identified. The authors extracted standards from 144 of those: 50 designated as ‘core’, 39 addressing trials of invasive procedures and a 5% sample of the remainder. As the integrating framework for the standards we developed a coherent taxonomy encompassing all elements of a trial's stages. Findings Review of the 144 documents yielded nearly 15 000 discrete standards. After duplicates were removed, 5903 substantive standards remained, distributed in the taxonomy as follows: initiation, 1401 standards, 8 divisions; design, 1869 standards, 16 divisions; conduct, 1473 standards, 8 divisions; analysing and reporting results, 997 standards, four divisions; and post-trial standards, 168 standards, 5 divisions. Conclusions The overwhelming number of source documents and standards uncovered in this study was not anticipated beforehand and confirms the extraordinary complexity of the clinical trials enterprise. This taxonomy of multinational ethical and methodological standards may help trialists and overseers improve the quality of clinical trials, particularly given the globalisation of clinical research.

O valor nutritivo do leite de ovelha é superior quando comparado aos leites caprino e bovino, apresentando maior teor proteico, lipídico, minerais e vitaminas. Os humanos evoluíram em estreito contato com a natureza, sendo o leite a primeira fonte de alimento desta espécie ao nascer. Durante milhares de anos, o leite rico em nutrientes, como fonte de alimento, era unicamente materno e só veio a ser consumido pelo homem após idade de amamentação com a domesticação dos animais, primeiramente às ovelhas (...) e as cabras há aproximadamente 13 mil anos, seguido da domesticação das vacas quatro mil anos depois. Desde então o leite tornou-se um alimento indispensável para o homem. O valor nutritivo do leite de ovelha é superior quando comparado aos leites caprino e bovino, apresentando maior teor proteico, lipídico, minerais e vitaminas essenciais para a saúde humana. Este leite apresenta três vezes mais proteínas em relação ao leite de cabra e de vaca, sendo aquelas consideradas proteínas de alto valor biológico contribuindo para uma melhor digestibilidade. Outra característica é a conformação estrutural e a quantidade de micelas de caseína e suas subunidades, que são assim como o leite caprino, menores que as do leite bovino, proporcionando menor sensibilização às pessoas alérgicas. Estudos sugerem que o leite de ovelha pode ser considerado o substituto ideal do leite bovino para pessoas alérgicas ao leite bovino devido ao elevado teor dos principais componentes do leite e minerais. Entretanto, foi verificado que anticorpos IgE de pessoas alérgicas reconhecem as αS1-caseína, αS2-caseína e β-caseína de leite ovino e caprino, mas caseínas do leite bovino são raramente ou não reconhecidas. Além disso, os polimorfismos genéticos das proteínas do leite estão associados com os parâmetros quantitativos e qualitativos e desempenham um papel importante na indução de diferentes graus de reação alérgica. A coloração do leite de ovelha é intensamente branca e homogênea, o que o difere do leite de vaca, pois essa característica está associada à ausência de β-caroteno pigmento precursor do retinol (vitamina A) impedindo que o leite tenha coloração amarelada como no caso do leite bovino. No leite ovino, o β-caroteno apresenta-se na forma convertida da vitamina A que não possui coloração amarelada e essa característica possibilita a produção de diferentes variedades de queijo. A caseína no leite de ovelha compõe 80% do total de proteínas do leite dos ruminantes, enquanto que está presente em 50% da composição proteica do leite equino e em menor porcentagem no leite humano. A caseína do leite de ruminantes difere com relação às características de tamanho, hidratação e mineralização. As micelas de caseína do leite de ovelha possuem maior mineralização e menor hidratação, sendo mais estáveis ao aquecimento quando comparadas à micela de caseína do leite de vaca. Outra importante característica refere-se à conformação molecular e sequencial de aminoácidos com impacto sobre sua digestibilidade, qualidade nutricional e termoestabilidade proteica. As proteínas do leite de ovelha consistem em elevada quantidade de caseínas (resistente ao calor) e proteínas do soro (sensível ao calor) responsáveis pela textura e viscosidade de iogurtes. Tecnologicamente, elas têm propriedades únicas que permitem a fácil conversão do leite em iogurte e queijos, não sendo necessária a adição de sólidos na produção do iogurte, como leite em pó, ou concentração dos sólidos do leite por tecnologia de membrana. Estudos com variantes da caseína do leite ovino representam uma abordagem eficaz para identificar a associação de características de importância econômica e melhorar raças para a produção de proteína do leite específica. As características da caseína no leite de ovelha são particularmente interessantes devido ao número elevado de polimorfismo, alterando a expressão de genes e influenciando o processamento de queijos. Em adição, enzimas presente no leite de ovelha possui atividade proteolítica e lipolítica (quebra de proteínas e lipídios). Elas auxiliam na maturação de queijos - resultando em compostos de aroma e sabor típicos, tornando-os únicos em suas características. O sabor e o aroma do leite de ovelha são suaves e adocicados além de possuir uma textura cremosa devido aos pequenos glóbulos de gordura que apresentam tamanhos menores que 3,5 µm. Esta peculiaridade no tamanho dos glóbulos gordurosos do leite ovino propicia que esse seja digerido mais facilmente. O leite ovino apresenta também altas concentrações de ácidos graxos poli-insaturados com benefícios à saúde como isômeros de ácido linoleico conjugado (CLA) presentes em maior concentração nesta matriz comparado ao leite bovino que são o cis-9 trans-11 e o trans-10 cis-12, responsáveis por ações anticarcinogênica, antiaterogênico e antiobesidade. Ainda com relação aos lipídios do leite de ovelha, as lipases têm um papel importante na produção de leite na glândula mamária. As lipases naturais do leite catalisam e hidrolisam os triglicerídeos, produzindo ácidos graxos livres (AGL). A atividade das lipases, em leite ovino, é cerca de um décimo das do leite bovino. Além disso, o padrão de hidrólise da gordura de leite por ovinos apresenta maior taxa em relação aos triglicerídeos - contendo ácidos graxos de cadeia média em relação aos ácidos graxos de cadeia longa. Os níveis de AGL em queijos de leite ovino são o resultado do processo lipolítico que ocorre durante o período de maturação. Alguns produtos lácteos derivados usando como matéria-prima o leite de ovelha - como iogurte grego e queijos - foram descritos como possuindo peptídeos inibidores da enzima conversora da angiotensina (ECA), sendo a maioria derivada da subunidade β-caseína. Também, alguns peptídeos derivados da κ-caseína, resultante da hidrólise de leite ovino pela pepsina, tripsina e quimotripsina, exercem atividade antioxidante. Em queijos tradicionais derivados de ovelha, como o Scamorza, foram verificados diversos peptídeos com ação inibidora da ECA e ação antibacteriana. Nesse contexto, o leite de ovelha é uma rica fonte de nutrientes e seu principal uso é na produção de queijos devido ao elevado conteúdo de extrato seco total, que contribui com alto rendimento da massa. Todavia, esta matéria-prima permanece inexplorada pela indústria de laticínios com uma visão de alimento funcional, visto que o leite e seus derivados são reconhecidamente ótimos carreadores de fibras prebióticas e bactérias probióticas - que trazem benefícios ao consumidor favorecendo saúde e bem-estar. Nesse contexto, o leite de ovelha apresenta-se como um alimento de grande potencial e uma valiosa alternativa para a indústria de laticínios - que pode aumentar a diversidade de produtos oferecidos ao consumidor.

We claim that a moral obligation to take climate leadership by means of unilateral mitigation depends on the existence of a plausible follow-the-leader mechanism whereby unilateral mitigation by some increases the probability of sufficient mitigation by others to avert catastrophic climate impacts. By understanding these mechanisms, we can better articulate the obligation for climate leadership across various sectors, from government to individual actors, in the fight against climate change.

In 2020, an international team of intercultural philosophers and African linguists created a multilinguistic game named Adinkra. This name refers to a medieval rooted symbolic language in Ghana that is actively used by the Akan and especially the Asante among them to communicate indirectly. The Akan is both the meta-ethnic name of the largest Ghanaian cultural-linguistic group of which the Asante is an Akan cultural subgroup and of a Central Tano language of which Asante-Twi is a dialect. The Adinkra symbols, (...) which have permeated Akan life and the arts, can be found e.g. on Asante royal staffs and gold weights. They are also loosely connected to Akan proverbs. The game Adinkra aims to enhance its players’ intercultural communicative, and moral philosophical understanding by matching Adinkra symbols with Akan proverbs. It was created for educational and therapeutical purposes. This article focusses on the rules, the making of Adinkra, its aims and objectives. The objective of this article is twofold. First, it focusses on the game itself. It elaborates on what its rules are and the content of the game. It also focusses on how playing the multilinguistic game, Adinkra can enhance intercultural understanding and communication. It, furthermore, concentrates on the results of a pilot reception study of this game in the Netherlands among intercultural groups of players. This study has proven that the Adinkra game stimulates creative thinking, engagement in dialogue and reflective ethical thinking. For this reason, the authors believe that it has a lot to contribute to intercultural educational programs with a focus on intercultural communication, philosophy and arts in both Africa and the global North. Finally, a section is devoted to the question of how the Adinkra game was developed and methodologically grounded in Gadamer’s playful hermeneutics, and the theories of the Wheel of the Intercultural Art of living and (African) Indigenous Religions. Secondly, the article focusses on the game’s oral-literary storytelling context and Akan moral ideas. It then throws the searchlight on the creative, therapeutic value and its potential to serve as a ‘cultural detox’. The authors and game makers think that being introduced to an African communitarian ethos hidden in the Adinkra symbols and Akan proverbs can help its players to develop a critical eye for the highly individualistic ethos of Western culture that, among others, is promoted by neoliberal thinking and praxis. The word praxis is used by the authors in the meaning found in educational contexts. Adinkra’s players are stimulated to reflect upon a different moral idea, which can change their mindset and put them into action to contribute to social awareness and societal change. (shrink)

A graph-theoretic account of logics is explored based on the general notion of m-graph (that is, a graph where each edge can have a finite sequence of nodes as source). Signatures, interpretation structures and deduction systems are seen as m-graphs. After defining a category freely generated by a m-graph, formulas and expressions in general can be seen as morphisms. Moreover, derivations involving rule instantiation are also morphisms. Soundness and completeness theorems are proved. As a consequence of the generality of the (...) approach our results apply to very different logics encompassing, among others, substructural logics as well as logics with nondeterministic semantics, and subsume all logics endowed with an algebraic semantics.

The scope of the sexual abuse of minors’ crises within the Catholic Church examined in conjunction with the purpose of temporal goods, the responsibility of the episcopate, the meaning of good stewardship, the faithful’s obligation to financially support the church, and compensation to alleged victims and their attorneys presents a realistic quandary for the Christifideles. -/- Should the Church replete with its perceived “deep pockets” be “selling off” temporal goods to remunerate lawsuits, which in some situations far exceed those of (...) other “institutions?” Should there be limits? Moreover, one ought to also contemplate whether there is a difference in the “handling” or disposition of sexual abuse cases involving minors when the competent authority has knowingly increased the risk of financial liability to the faithful. What should happen? This brief analysis seeks to examine the above questions as they apply to dioceses in the U.S. and its territories. Inquiry concerning canon 1254, inter alia in the 1983 Code of Canon Law may allow insight vis-à-vis the connotation of “temporal goods,” their application, and relevancy to restitution regarding the sexual abuse of minors. -/- .

This article examines two manga, Stop!! Hibari-Kun! and No Bra, which prefigure the increasingly popular anime and manga genre of otokonoko from a queer studies perspective. Otokonoko, also known as otoko no musume, is a genre of manga in which persons assigned male at birth (AMAB) wear women’s clothing and are perceived as attractive women. The term otokonoko (男の娘) is pronounced identically to the term男の子, meaning boy-child; however, due to a pun in the kanji which replaces "child" (子) with "daughter"/"girl" (...) (娘), it translates to “boy-girl”, “boy-daughter”, or sometimes“boy-princess”. It is often translated into English as “cross-dresser”. The genre emerged in the early 2000s and has since become a popular point of reference and conversation both within and outside of anime and manga communities. Both the genre, and its titular characters have become iconic within both Japanese and Western online culture. As with most genres, the otokonoko genre is trope heavy, so I decided to look at works that prefigure the genre to better understand the appeal without the weight of the traditions of the genre weighing too heavily on the content. Both Stop!! Hibari-Kun! and No Bra follow the story of a boy who becomes increasingly attracted to a gender ambiguous character assigned male at birth, but who appears female to most. Both manga are centrally about this conflict between the love interests’ perceived maleness and the protagonists perceived heterosexuality. The article analyses the appeal of each work to both male and trans feminine readers, because what would later become the otokonoko genre is popular with both male and trans feminine readers. It also argues that these manga offer something unique from Western depictions of transgender lives, based on the popularity of manga and anime among Western trans feminine readers. (shrink)

Due to Gӧdel’s incompleteness results, the categoricity of a sufficiently rich mathematical theory and the semantic completeness of its underlying logic are two mutually exclusive ideals. For first- and second-order logics we obtain one of them with the cost of losing the other. In addition, in both these logics the rules of deduction for their quantifiers are non-categorical. In this paper I examine two recent arguments –Warren (2020), Murzi and Topey (2021)– for the idea that the natural deduction rules for (...) the first-order universal quantifier are categorical, i.e., they uniquely determine its semantic intended meaning. Both of them make use of McGee’s open-endedness requirement and the second one uses in addition Garson’s (2013) local models for defining the validity of these rules. I argue that the success of both these arguments is relative to their semantic or infinitary assumptions, which could be easily discharged if the introduction rule for the universal quantifier is taken to be an infinitary rule, i.e. non-compact. Consequently, I reconsider the use of the ω-rule and I show that the addition of the ω-rule to the standard formalizations of first-order logic is categorical. In addition, I argue that the open-endedness requirement does not make the first-order Peano Arithmetic categorical and I advance an argument for its categoricity based on the inferential conservativity requirement.

Most event-referring expressions are vague; it is utterly difficult, if not impossible, to specify the exact spatiotemporal location of an event from the words that we use to refer to it. We argue that in spite of certain prima facie obstacles, such vagueness can be given a purely semantic (broadly supervaluational) account.

Recent research has relied on trolley-type sacrificial moral dilemmas to study utilitarian versus nonutili- tarian modes of moral decision-making. This research has generated important insights into people’s attitudes toward instrumental harm—that is, the sacrifice of an individual to save a greater number. But this approach also has serious limitations. Most notably, it ignores the positive, altruistic core of utilitarianism, which is characterized by impartial concern for the well-being of everyone, whether near or far. Here, we develop, refine, and validate a (...) new scale—the Oxford Utilitarianism Scale—to dissociate individual differences in the ‘negative’ (permissive attitude toward instrumental harm) and ‘positive’ (impartial concern for the greater good) dimensions of utilitarian thinking as manifested in the general population. We show that these are two independent dimensions of proto-utilitarian tendencies in the lay population, each exhibiting a distinct psychological profile. Empathic concern, identification with the whole of humanity, and concern for future generations were positively associated with impartial beneficence but negatively associated with instrumental harm; and although instrumental harm was associated with subclinical psychopathy, impartial beneficence was associated with higher religiosity. Importantly, although these two dimensions were independent in the lay population, they were closely associated in a sample of moral philosophers. Acknowledging this dissociation between the instrumental harm and impartial beneficence components of utilitarian thinking in ordinary people can clarify existing debates about the nature of moral psychology and its relation to moral philosophy as well as generate fruitful avenues for further research.

I consider two attempts to combine realism with pluralism about the units of selection: Sober and Wilson’s combination of “model” and “unit” pluralism, and Sterelny and Griffiths’ “local pluralism”. I argue that both of these attempts fail to show that realism and pluralism are compatible. Sober and Wilson’s pluralism turns out, on closer inspection, to be a kind of monism in disguise, while Sterelny and Griffiths’ local pluralism involves a combination of realism and anti-realism about interactors, and the units of (...) selection, that is fundamentally unstable. My conclusion is that one must choose whether to be a realist or a pluralist in this area: one cannot be both. The question of which we should choose is a further question that I do not take a stand on. (shrink)

I argue that the Conceptual Ethics and Conceptual Engineering framework, in its pragmatist version as recently defended by Thomasson (2017, 2020), provides a means of articulating and defending the conventionalist interpretation of projects of conceptual extension (e.g. the extended mind, the extended phenotype) in biology and psychology. This promises to be illuminating in both directions: it helps to make sense of, and provides an explicit methodology for, pragmatic conceptual extension in science, while offering further evidence for the value and fruitfulness (...) of the conceptual ethics/engineering framework itself, in particular with respect to conceptual change within science, which has thus-far received little attention in the literature on conceptual ethics/engineering.

This short article discusses the fact that the word ‘ancestor’ features in certain arguments that a) are apparently logically valid, b) contain infinitely many premises, and c) are such that none of their finite sub-arguments are logically valid. The article's aim is to motivate, within its brief compass, the study of infinitary logics.

Logical inferentialism maintains that the formal rules of inference fix the meanings of the logical terms. The categoricity problem points out to the fact that the standard formalizations of classical logic do not uniquely determine the intended meanings of its logical terms, i.e., these formalizations are not categorical. This means that there are different interpretations of the logical terms that are consistent with the relation of logical derivability in a logical calculus. In the case of the quantificational logic, the categoricity (...) problem is generated by the finite nature of the standard calculi and one direction in which it can be solved is to strengthen the deductive systems by adding infinitary rules (such as the ω-rule), i.e., to construct a full formalization. Another main direction is to provide a natural semantics for the standard rules of inference, i.e., a semantics for which these rules are categorical. My aim in this paper is to analyze some recent approaches for solving the categoricity problem and to argue that a logical inferentialist should accept the infinitary rules of inference for the first order quantifiers, since our use of the expressions “all” and “there is” leads us beyond the concrete and finite reasoning, and human beings do sometimes employ infinitary rules of inference in their reasoning.

This paper focuses on invasive therapeutic procedures, defined as procedures requiring the introduction of hands, instruments, or devices into the body via incisions or punctures of the skin or mucous membranes performed with the intent of changing the natural history of a human disease or condition for the better. Ethical and methodological concerns have been expressed about studies designed to evaluate the effects of invasive therapeutic procedures. Can such studies meet the same standards demanded of those, for example, evaluating pharmaceutical (...) agents? This paper describes a research project aimed at examining the interplay and sometimes apparent conflict between ethical standards for human research and standards for methodological rigor in trials of invasive procedures. The paper discusses how the authors plan to develop a set of consensus standards that, if met, would result in substantial and much-needed improvements in the methodological and ethical quality of such trials.

A brief article introducing *One True Logic*. The book argues that there is one correct foundational logic and that it is highly infinitary.

Cladism, today the dominant school of systematics in biology, includes a classification component – the view that classification ought to reflect phylogeny only, such that all and only taxa are monophyletic (i.e. consist of an ancestor and all its descendants) - and a metaphysical component – the view that all and only real groups or kinds of organisms are monophyletic. For the most part these are seen as amounting to much the same thing, but I argue they can and should (...) be distinguished, in particular that cladists about classification need not accept the typically cladist view about real groups or kinds. Cladists about classification can and should adopt an explanatory criterion for the reality of groups or kinds, on which being monophyletic is neither necessary nor sufficient for being real or natural. Thus the line of reasoning that has rightly led to cladism becoming dominant within systematics, and the attractive line of reasoning in the philosophical literature that advocates a more liberal approach to natural kinds, are seen to be, contrary to appearances, compatible.

It is not a particularly hard thing to want or seek explanations. In fact, explanations seem to be a large and natural part of our cognitive lives. Children ask why and how questions very early in development and seem genuinely to want some sort of answer, despite our often being poorly equipped to provide them at the appropriate level of sophistication and detail. We seek and receive explanations in every sphere of our adult lives, whether it be to understand why (...) a friendship has foundered, why a car will not start, or why ice expands when it freezes. Moreover, correctly or incorrectly, most of the time we think we know when we have or have not received a good explanation. There is a sense both that a given, successful explanation satisfies a cognitive need, and that a questionable or dubious explanation does not. There are also compelling intuitions about what make good explanations in terms of their form, that is, a sense of when they are structured correctly. (shrink)

Whenever science returns a confident and univocal answer to a question, Trumping Naturalism enjoins us to accept it. The majority of contemporary philosophers are sympathetic to this sort of position. Indeed, several have endorsed it or something very close to it. Arguments for Trumping Naturalism, however, are scant, the principal one being the Track Record Argument. The argument is based on the fact that in cases of conflict, science has a better track record than non-scientific forms of inquiry such as (...) philosophy. My chapter investigates this argument. I enumerate and assess several objections to the argument, from footling objections to stronger ones. My conclusion is that the Track Record Argument is not as strong as imagined. (shrink)

This thesis is about making decisions when we are uncertain about what will happen, how valuable it will be, and even how to make decisions. Even the most sure-footed amongst us are sometimes uncertain about all three, but surprisingly little attention has been given to the latter two. The three essays that constitute my thesis hope to do a small part in rectifying this problem. The first essay is about the value of finding out how to make decisions. Society spends (...) considerable resources funding people (like me) to research decision-making, so it is natural to wonder whether society is getting a good deal. This question is so shockingly underresearched that bedrock facts are readily discoverable, such as when this kind of information is valuable. My second essay concerns whether we can compare value when we are uncertain about value. Many people are in fact uncertain about value, and how we deal with this uncertainty hinges on these comparisons. I argue that value comparisons are only sometimes possible; I call this weak comparability. This essay is largely a synthesis of the literature, but I also present an argument which begins with a peculiar view of the self: it is as if each of us is a crowd of different people separated by time (but connected by continuity of experience). I’m not the first to endorse this peculiar view of the self, but I am the first to show how it supports the benign view that value is sometimes comparable. We may be uncertain of any decision rules, even those that would tell us how to act when we face uncertainty in decision rules. We may be uncertain of how to decide how to decide how to... And so on. If so, we might have to accept infinitely many decision rules just to make any mundane decision, such as whether to pick up a five-cent piece from the gutter. My third essay addresses this problem of regress. I think all of our decisions are forced: we must decide now or continue to deliberate. Surprisingly, this allows us to avoid the original problem. I call this solution “when forced, do your best”. (shrink)

Vann McGee has recently argued that Belnap’s criteria constrain the formal rules of classical natural deduction to uniquely determine the semantic values of the propositional logical connectives and quantifiers if the rules are taken to be open-ended, i.e., if they are truth-preserving within any mathematically possible extension of the original language. The main assumption of his argument is that for any class of models there is a mathematically possible language in which there is a sentence true in just those models. (...) I show that this assumption does not hold for the class of models of classical propositional logic. In particular, I show that the existence of non-normal models for negation undermines McGee’s argument. (shrink)

Euclid’s Elements inspired a number of foundationalist accounts of mathematics, which dominated the epistemology of the discipline for many centuries in the West. Yet surprisingly little has been written by recent philosophers about this conception of mathematical knowledge.

In this essay, we examine Lakatos’s account of the Euclidean Programme with a critical eye, and suggest an alternative (...) picture which builds on his work, but differs in a number of important respects.

This study explores the impact of regional comprehensive factors on talent acquisition using the ASA (Attraction-Selection-Attrition) theory within the context of the automotive industry, employing a structural equation modeling approach. Analyzing data from 308 respondents, the study identifies significant relationships between regional development pole, industry agglomeration, and regional incentives with various dimensions of talent acquisition, including attraction, selection, and retention. The findings reveal that regional development pole and incentives positively influence talent management processes, whereas industry agglomeration has a detrimental effect. (...) These insights are essential for formulating strategies to enhance talent acquisition and retention in the automotive industry by leveraging regional development and incentive mechanisms while addressing the challenges posed by industrial agglomeration.

What is the primary function of consciousness in the nervous system? The answer to this question remains enigmatic, not so much because of a lack of relevant data, but because of the lack of a conceptual framework with which to interpret the data. To this end, we have developed Passive Frame Theory, an internally coherent framework that, from an action-based perspective, synthesizes empirically supported hypotheses from diverse fields of investigation. The theory proposes that the primary function of consciousness is well-circumscribed, (...) serving the 'somatic nervous system[. For this system, consciousness serves as a frame that constrains and directs skeletal muscle output, thereby yielding adaptive behavior. The mechanism by which consciousness achieves this is more counterintuitive, passive, and “low level” than the kinds of functions that theorists have previously attributed to consciousness. Passive frame theory begins to illuminate (a) what consciousness contributes to nervous function, (b) how consciousness achieves this function, and (c) the neuroanatomical substrates of conscious processes. Our untraditional, action-based perspective focuses on olfaction instead of on vision and is 'descriptive' (describing the products of nature as they evolved to be) rather than 'normative' (construing processes in terms of how they should function). Passive frame theory begins to isolate the neuroanatomical, cognitive-mechanistic, and representational (e.g., conscious contents) processes associated with consciousness. (shrink)

Essential Microeconomics is designed to help students deepen their understanding of the core theory of microeconomics. Unlike other texts, this book focuses on the most important ideas and does not attempt to be encyclopedic. Two-thirds of the textbook focuses on price theory. As well as taking a new look at standard equilibrium theory, there is extensive examination of equilibrium under uncertainty, the capital asset pricing model, and arbitrage pricing theory. Choice over time is given extensive coverage and includes a basic (...) introduction to control theory. The final third of the book, on game theory, provides a comprehensive introduction to models with asymmetric information. Topics such as auctions, signaling and mechanism design are made accessible to students who have a basic rather than a deep understanding of mathematics. Examples and diagrams are used to illustrate issues as well as formal derivations. (shrink)

A graph-theoretic account of fibring of logics is developed, capitalizing on the interleaving characteristics of fibring at the linguistic, semantic and proof levels. Fibring of two signatures is seen as a multi-graph (m-graph) where the nodes and the m-edges include the sorts and the constructors of the signatures at hand. Fibring of two models is a multi-graph (m-graph) where the nodes and the m-edges are the values and the operations in the models, respectively. Fibring of two deductive systems is an (...) m-graph whose nodes are language expressions and the m-edges represent the inference rules of the two original systems. The sobriety of the approach is confirmed by proving that all the fibring notions are universal constructions. This graph-theoretic view is general enough to accommodate very different fibrings of propositional based logics encompassing logics with non-deterministic semantics, logics with an algebraic semantics, logics with partial semantics and substructural logics, among others. Soundness and weak completeness are proved to be preserved under very general conditions. Strong completeness is also shown to be preserved under tighter conditions. In this setting, the collapsing problem appearing in several combinations of logic systems can be avoided. (shrink)

The revival of the philosophy of mathematics in the 60s following its post-1931 slump left us with two conflicting positions on arithmetic’s ontological relationship to set theory. W.V. Quine’s view, presented in 'Word and Object' (1960), was that numbers are sets. The opposing view was advanced in another milestone of twentieth-century philosophy of mathematics, Paul Benacerraf’s 'What Numbers Could Not Be' (1965): one of the things numbers could not be, it explained, was sets; the other thing numbers could not be, (...) even more dramatically, was objects. Curiously, although Benacerraf’s article appeared in the heyday of Quine’s influence, it declined to engage the Quinean position squarely, even seemed to think it was not its business to do so. Despite that, in my experience, most philosophers believe that Benacerraf’s article put paid to the reductionist view that numbers are sets (though perhaps not the view that numbers are objects). My chapter will attempt to overturn this orthodoxy. (shrink)

The concern of deductive logic is generally viewed as the systematic recognition of logical principles, i.e., of logical truths. This paper presents and analyzes different instantiations of the three main interpretations of logical principles, viz. as ontological principles, as empirical hypotheses, and as true propositions in virtue of meanings. I argue in this paper that logical principles are true propositions in virtue of the meanings of the logical terms within a certain linguistic framework. Since these principles also regulate and control (...) the process of deduction in inquiry, i.e., they are prescriptive for the use of language and thought in inquiry, I argue that logic may, and should, be seen as an instrument or as a way of proceeding (modus procedendi) in inquiry.

K. R. Popper distinguished between two main uses of logic, the demonstrational one, in mathematical proofs, and the derivational one, in the empirical sciences. These two uses are governed by the following methodological constraints: in mathematical proofs one ought to use minimal logical means (logical minimalism), while in the empirical sciences one ought to use the strongest available logic (logical maximalism). In this paper I discuss whether Popper’s critical rationalism is compatible with a revision of logic in the empirical sciences, (...) given the condition of logical maximalism. Apparently, if one ought to use the strongest logic in the empirical sciences, logic would remain immune to criticism and, thus, non-revisable. I will show that critical rationalism is theoretically compatible with a revision of logic in the empirical sciences. However, a question that remains to be clarified by the critical rationalists is what kind of evidence would lead them to revise the system of logic that underlies a physical theory, such as quantum mechanics? Popper’s falsificationist methodology will be compared with the recently advocated extension of the abductive methodology from the empirical sciences to logic by T. Williamson, since both of them arrive at the same conclusion concerning the status of classical logic. (shrink)

Warning: includes two somewhat graphic images. This paper is an effort to lay out a taxomony of conceptual relations between the domains of the sublime and the religious. -/- .

O artigo oferece uma breve exposição da biografia e do contexto histórico do filósofo neoplatônico Damáscio (c. 458 - c. 538) para, na sequência, apresentar a tradução de um dos seus poemas líricos do período final de sua vida. O procedimento adotado justifica-se pelo caráter lutuoso e decididamente pessoal dos versos, nos quais Damáscio lamenta consigo próprio as perdas sofridas no decorrer de sua longa e fascinante vida. Como veremos, tais perdas estão, em verdade, diretamente ligadas ao colapso do mundo (...) antigo e ao derradeiro golpe proferido por Justiniano contra a filosofia helênica pagã. (shrink)

Is the societal-level of analysis sufficient today to understand the values of those in the global workforce? Or are individual-level analyses more appropriate for assessing the influence of values on ethical behaviors across country workforces? Using multi-level analyses for a 48-society sample, we test the utility of both the societal-level and individual-level dimensions of collectivism and individualism values for predicting ethical behaviors of business professionals. Our values-based behavioral analysis indicates that values at the individual-level make a more significant contribution to (...) explaining variance in ethical behaviors than do values at the societal-level. Implicitly, our findings question the soundness of using societal-level values measures. Implications for international business research are discussed. (shrink)

In mathematics, the deductive method reigns. Without proof, a claim remains unsolved, a mere conjecture, not something that can be simply assumed; when a proof is found, the problem is solved, it turns into a “result,” something that can be relied on. So mathematicians think. But is there more to mathematical justification than proof? -/- The answer is an emphatic yes, as I explain in this article. I argue that non-deductive justification is in fact pervasive in mathematics, and that it (...) is in good epistemic standing. (shrink)

The ontological turn (OT) is a loose cluster of theoretical approaches within cultural anthropology that advocates a synthetic, overarching way forward for ethnographically oriented cultural anthropology. We argue that in order to contribute substantively to ethnobiology the OT needs to distance itself from a long-standing tradition of thinking within ethnography that assumes some kind of fundamental divide between the natural and the social sciences. This distancing seems especially unlikely in light of the meta-anthropological nature of the OT as primarily a (...) perspective on ethnographic methodology. Instead, we advocate for naturalistic theoretical alternatives for thinking about human sociality, where philosophical innovation develops in concert with ongoing empirical work across the biological, cognitive, and social sciences. We illustrate this perspective by drawing on two naturalistic accounts likely to prove more fruitful for ethnobiological practice, namely, trans-genera models of sociality and progenerative views of kinship.

Starting from certain metalogical results, I argue that first-order logical truths of classical logic are a priori and necessary. Afterwards, I formulate two arguments for the idea that first-order logical truths are also analytic, namely, I first argue that there is a conceptual connection between aprioricity, necessity, and analyticity, such that aprioricity together with necessity entails analyticity; then, I argue that the structure of natural deduction systems for FOL displays the analyticity of its truths. Consequently, each philosophical approach to these (...) truths should account for this evidence, i.e., that first-order logical truths are a priori, necessary, and analytic, and it is my contention that the semantic account is a better candidate.
