The first part of the essay examines the different premises, of Aristotelian and Galenic origin, for the idea of an inherent consumption of the natural heat of every living body, discussing the contributions of Isaac Israeli, Avicenna and Averroes to the reflection on the relationship between the secondary humours (or moistures) and the peculiar category of fevers called ‘hectic’. The second part of the article discusses how the link between moisture, heat and food was taken up and elaborated (...) by Latin Scholastic masters (in particular Thomas Aquinas), and considers the use of the notion of ‘radical moisture’ in the field of theology. Aquinas does not follow the previous theological tradition, originating with Peter Lombard, which denies the possibility that the matter assimilated through food is part of the bodily core that belongs to every human being from birth. The moisture provided by food is, in fact, inseparable from the (radical) moisture that originally belongs to each individual; as such, it is part of the ‘truth of human nature’ (veritas humanae naturae) that will be restored at the moment of the resurrection of the body.

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.

Ancient Greek philosophers were the first to postulate the possibility of explaining nature in theoretical terms and to initiate attempts at this. With the rise of monotheistic religions of revelation claiming supremacy over human reason and envisaging a new world to come, studies of the natural order of the transient world were widely considered undesirable. Later, in the Middle Ages, the desire for human understanding of nature in terms of reason was revived. This article is concerned with the fundamental reversal (...) of attitudes, from “undesirable” to “desirable”, that eventually led into the foundations of modern science. One of the earliest, most ingenious and most interesting personalities involved was Eriugena, a theologian at the Court of Charles the Bald in the 9th century. Though understanding what we call nature is only one of the several aspects of his theological work, his line of thought implies a turn into a pro-scientific direction: the natural order is to be understood in abstract terms of ‘primordial causes’; understanding nature is considered to be the will of God; man encompasses the whole of creation in a physical as well as a mental sense. Basically similar ideas on the reconciliation of scientific rationality and monotheistic religions of revelation were conceived, independently and nearly simultaneously, by the Arab philosopher al-Kindi in Bagdad. Eriugena was more outspoken in his claim that reason is superior to authority. This claim is implicit in the thought of Nicholas of Cusa with his emphasis on human mental creativity as the image of God’s creativity; and it is the keynote of Galileo’s ‘Letter to the Grand Duchess Christina’ some 800 years later, the manifesto expressing basic attitudes of modern science. -/- This article in English is based on the monography (in German): A.

Conceptual engineering is the method for assessing and improving our concepts. However, little has been written about how best to conceive of concepts for the purposes of conceptual engineering. In this paper, I aim to fill this foundational gap, proceeding in three main steps: First, I propose a methodological framework for evaluating the conduciveness of a given concept of concept for conceptual engineering. Then, I develop a typology that contrasts two competing concepts of concept that can be used in conceptual (...) engineering — namely, the philosophical and psychological ones. Finally, I evaluate these two concepts of concept using the proposed methodological framework and I show that, when it comes to making conceptual engineering an actionable method, the psychological concept of concept outclasses its philosophical counterpart on all counts. This provides a baseline from which the concept of concept can be further improved for the purposes of conceptual engineering. (shrink)

We explore the ethics of using motivational interviewing, an evidence-based, client-centred and directional counselling method, in conversations with next of kin about deceased solid organ donation. After briefly introducing MI and providing some context around organ transplantation and next of kin consent, we describe how MI might be implemented in this setting, with the hypothesis that MI has the potential to bring about a modest yet significant increase in next of kin consent rates. We subsequently consider the objection that using (...) MI in this context would be manipulative. Although we cannot guarantee that MI would never be used in a problematically manipulative fashion, we conclude that its use would, nevertheless, be permissible as a potential means to increase next of kin consent to deceased solid organ donation. We propose that MI be trialled in consent situations with next of kin in nations where there is widespread public support for organ donation. (shrink)

This paper discusses the logical space of alternative conceptual engineering projects, with a specific focus on (1) the processes, (2) the targets and goals, and (3) the methods of such projects. We present an overview of how these three aspects interact in the contemporary literature and discuss those alternative projects that have yet to be explored based on our suggested typology. We show how choices about each element in a conceptual engineering project constrain the possibilities for the others, thereby giving (...) rise to distinct groupings of possible projects under the banner of conceptual engineering. We conclude with a critical reflection on the potential ethical issues that arise as a result of effectively putting conceptual engineering into practice. (shrink)

Conceptual engineering means to provide a method to assess and improve our concepts working as cognitive devices. But conceptual engineering still lacks an account of what concepts are (as cognitive devices) and of what engineering is (in the case of cognition). And without such prior understanding of its subject matter, or so it is claimed here, conceptual engineering is bound to remain useless, merely operating as a piecemeal approach, with no overall grip on its target domain. The purpose of this (...) programmatic paper is to overcome this knowledge gap by providing some guidelines for developing the theories of concepts and of cognition that will ground the systematic unified framework needed to effectively implement conceptual engineering as a widely applicable method for the cognitive optimization of our conceptual devices.

Roughly put, explanatory circles — if any exist — would be propositions such that (i) each explains the next, and (ii) the last explains the first. In this paper, I give two arguments for the view that there are explanatory circles. The first argument appeals to general relativistic worlds in which time is circular. The second argument appeals to special science theories that describe feedback loops. In addition, I show that three standard arguments against explanatory circles are unsuccessful.

I formulate a theory of groups based on pluralities and counterparts: roughly put, a group is a plurality of entities at a time. This theory comes with counterpart-theoretic semantics for modal and temporal sentences about groups. So this theory of groups is akin to the stage theory of material objects: both take the items they analyze to exist at a single time, and both use counterparts to satisfy certain conditions relating to the modal properties, temporal properties, and coincidence properties of (...) those items.

My aim in this paper is to give a philosophical analysis of the relationship between contingently available technology and the knowledge that it makes possible. My concern is with what specific subjects can know in practice, given their particular conditions, especially available technology, rather than what can be known “in principle” by a hypothetical entity like Laplace’s Demon. The argument has two parts. In the first, I’ll construct a novel account of epistemic possibility that incorporates two pragmatic conditions: responsibility and (...) practicability. For example, whether subjects can gain knowledge depends in some circumstances on whether they have the capability of gathering relevant evidence. In turn, the possibility of undertaking such investigative activities depends in part on factors like ethical constraints, economical realities, and available technology. In the second part of the paper, I’ll introduce “technological possibility” to analyze the set of actions made possible by available technology. To help motivate the problem and later test my proposal, I’ll focus on a specific historical case, one of the earliest uses of digital electronic computers in a scientific investigation. I conclude that the epistemic possibility of gaining access to scientific knowledge about certain subjects depends (in some cases) on the technological possibility for making responsible investigations.

Conceptual engineering is the method for assessing and improving our concepts. Some have recently claimed that the implementation of such method in the form of ameliorative projects is truth-driven and should thus be epistemically constrained, ultimately at least (Simion 2018; cf. Podosky 2018). This paper challenges that claim on the assumption of a social constructionist analysis of ideologies, and provides an alternative, pragmatic and cognitive framework for determining the legitimacy of ameliorative conceptual projects overall. The upshot is that one should (...) not ameliorate for the sake of truth or knowledge, in the case of ideologies—at least, not primarily. (shrink)

Conceptual engineering is the method for assessing and improving our representational devices. On its ‘broad-spectrum’ version, it is expected to be appropriately applicable to any of our representation-involving cognitive activities, with major consequences for our whole cognitive life. This paper is about the theoretical foundations of conceptual engineering thus characterised. With a view to ensuring the actionability of conceptual engineering as a broad-spectrum method, it addresses the issue of how best to construe the subject matter of conceptual engineering and successively (...) defends the theses that conceptual engineering should be: (i) About concepts, (ii) psychologically theorised, (iii) as multiply realised functional kinds. Thereby, I claim to theoretically secure and justify the maximum scope, flexibility, and impact for the method of conceptual engineering on our representational devices in our whole cognitive life—in other words, a broad-spectrum version of conceptual engineering.

Is the fact that our universe contains fine-tuned life evidence that we live in a multiverse? Ian Hacking and Roger White influentially argue that it is not. We approach this question through a systematic framework for self-locating epistemology. As it turns out, leading approaches to self-locating evidence agree that the fact that our own universe contains fine-tuned life indeed confirms the existence of a multiverse. This convergence is no accident: we present two theorems showing that, in this setting, any updating (...) rule that satisfies a few reasonable conditions will have the same feature. The conclusion that fine-tuned life provides evidence for a multiverse is hard to escape. (shrink)

The centered Everett interpretation solves a problem that various approaches to quantum theory face. In this paper, I continue developing the theory underlying that solution. In particular, I defend the centered Everett interpretation against a few objections, and I provide additional motivation for some of its key features.

We present a novel model of individual people, online posts, and media platforms to explain the online spread of epistemically toxic content such as fake news and suggest possible responses. We argue that a combination of technical features, such as the algorithmically curated feed structure, and social features, such as the absence of stable social-epistemic norms of posting and sharing in social media, is largely responsible for the unchecked spread of epistemically toxic content online. Sharing constitutes a distinctive communicative act, (...) governed by a dedicated norm and motivated to a large extent by social identity maintenance. But confusion about this norm and its lack of inherent epistemic checks lead readers to misunderstand posts, attribute excess or insufficient credibility to posts, and allow posters to evade epistemic accountability—all contributing to the spread of epistemically toxic content online. This spread can be effectively addressed if people and platforms add significantly more context to shared posts and platforms nudge people to develop and follow recognized epistemic norms of posting and sharing.

Sometimes you are unreliable at fulfilling your doxastic plans: for example, if you plan to be fully confident in all truths, probably you will end up being fully confident in some falsehoods by mistake. In some cases, there is information that plays the classical role of evidence—your beliefs are perfectly discriminating with respect to some possible facts about the world—and there is a standard expected‐accuracy‐based justification for planning to conditionalize on this evidence. This planning‐oriented justification extends to some cases where (...) you do not have transparent evidence, in the sense that your beliefs are not perfectly discriminating with respect to any non‐trivial facts. In other cases, accuracy considerations do not tell you to plan to conditionalize on any information at all, but rather to plan to follow a different updating rule. Even in the absence of evidence, accuracy considerations can guide your doxastic plan. (shrink)

Suppose that, for reasons of animal welfare, it would be better if everyone stopped eating chicken. Does it follow that you should stop eating chicken? Proponents of the “inefficacy objection” argue that, due to the scale and complexity of markets, the expected effects of your chicken purchases are negligible. So the expected effects of eating chicken do not make it wrong. -/- We argue that this objection does not succeed, in two steps. First, empirical data about chicken production tells us (...) that the expected effects of consuming *many* chickens are not negligible. Second, this implies that the expected effect of consuming one chicken is ordinarily not negligible. *Parity* between your purchase and other counterfactual purchases and *uncertainty* about others’ consumption behavior each tend to pull the expected effect of a single purchase toward the average large scale effect. While some purchases do have negligible expected effects, many do not. (shrink)

This first critical edition of Isaac Abravanel’s correspondence opens a window into the cultural, political and commercial world of one of the first Jewish humanists of the quattrocento. Jewish leader of the expelled Sephardim after 1492, commentator of the Bible, Abravanel is a legendary figure of the Sephardic history. The edition of the letters along with the introductive essay that reconstructs their cultural background intends to connect the legendary figure of Abravanel to the major reason of his remarkable career: (...) his successful assimilation of Renaissance humanism.

This article is about the information relevant to decision-making capacity in refusal of life-prolonging medical treatment cases. We examine the degree to which the phenomenology of the options available to the agent—what the relevant states of affairs will feel like for them—forms part of the capacity-relevant information in the law of England and Wales, and how this informational basis varies across adolescent and adult medical treatment cases. We identify an important doctrinal phenomenon. In the leading authorities, the courts appear to (...) count the first-personal phenomenology of the available options among the information that adolescents seeking to refuse life-prolonging treatment must understand and appreciate in order to possess capacity; adults are not held to this (higher) standard. We evaluate this differential treatment in light of philosophical work on transformative choice—decisions involving options whose sensory character, and effect on our values and preferences, are grasped only through experience itself.

Leading prescriptions for addressing the spread of fake news, misinformation, and other forms of epistemically toxic content online target either the platform or platform users as a single site for intervention. Neither approach attends to the intense feedback between people, posts, and platforms. Leading prescriptions boil down to the suggestion that we make social media more like traditional media, whether by making platforms take active roles as gatekeepers, or by exhorting individuals to behave more like media professionals. Both approaches are (...) impracticable and wrong. (shrink)

I propose an account of probability in the Everett interpretation of quantum mechanics. According to the account, probabilities are objective chances of centered propositions. As I show, the account solves a number of problems concerning the role of probability in the Everett interpretation. It also challenges an implicit assumption, concerning the aim and scope of fundamental physical theories, that is made throughout the philosophy of physics literature.

Recent empirical work suggests that emotions are responsible for anti-consequentialist intuitions. For instance, anger places value on actions of revenge and retribution, value not derived from the consequences of these actions. As a result, it contributes to the development of retributive intuitions. I argue that if anger evolved to produce these retributive intuitions because of their biological consequences, then these intuitions are not a good indicator that punishment has value apart from its consequences. This severs the evidential connection between retributive (...) intuitions and the retributive value of punishment. This argument may generalize to other deontological intuitions and theories.

I explore the relationship between a prominent analysis of intrinsic properties, due to Langton and Lewis, and the phenomenon of quantum entanglement. As I argue, the analysis faces a puzzle. The full analysis classifies certain properties of entangled particles as intrinsic. But when combined with an extremely plausible assumption about duplication, the main part of the analysis classifies those properties as non-intrinsic instead. I conclude that much of Lewis’s metaphysics is in trouble: Lewis based many of his metaphysical views—his thesis (...) of Humean supervenience, for instance, and his account of recombination—on an analysis of intrinsicality which does not sit well with quantum phenomena.

I show that centered propositions—also called de se propositions, and usually modeled as sets of centered worlds—pose a serious problem for various versions of Lewis's Principal Principle. The problem, put roughly, is that in scenarios like Elga's `Sleeping Beauty' case, those principles imply that rational agents ought to have obviously irrational credences. To solve the problem, I propose a centered version of the Principal Principle. My version allows centered propositions to be objectively chancy.

If a proposition is typically true, given your evidence, then you should believe that proposition; or so I argue here. In particular, in this paper, I propose and defend a principle of rationality---call it the `Typical Principle'---which links rational belief to facts about what is typical. As I show, this principle avoids several problems that other, seemingly similar principles face. And as I show, in many cases, this principle implies the verdicts of the Principal Principle: so ultimately, the Typical Principle (...) may be the more fundamental of the two. (shrink)

Thomas Hurka’s recursive account of value appeals to certain intuitions to expand the class of intrinsic values, placing concepts of virtue and desert within the realm of second and third order intrinsic goods, respectively. This is a formalization of a tradition of thought extending back to Aristotle and Kant via the British moralists, G. E. Moore, and W. D. Ross. However, the evidential status of such intuitions vis a vis the real, intrinsic value of virtue and desert is hostage to (...) alternative explanations. If there is a plausible competing explanation for these intuitions, then the (putative) fact that desert and virtue are intrinsic (rather than instrumental or derivative) goods seems a much less obvious choice for the best explanation. As it turns out, there are plausible evolutionary explanations for these intuitions about desert and virtue. These evolutionary explanations suggest that it is adaptive to value desert and virtue separately from their instrumentality for other goods. Consequently, these explanations debunk intuitions about the intrinsic value of desert and virtue. (shrink)

David Chalmers thinks his iPhone exemplifies the extended mind thesis by meeting the criteria ‎that he and Andy Clark established in their well-known 1998 paper. Andy Clark agrees. We take ‎this proposal seriously, evaluating the case of the GPS-enabled smartphone as a potential mind ‎extender. We argue that the “trust and glue” criteria enumerated by Clark and Chalmers are ‎incompatible with both the epistemic responsibilities that accompany everyday activities and the ‎practices of trust that enable users to discharge them. Prospects (...) for revision of the original ‎criteria are dim. We therefore call for a rejection of the trust criterion and a reevaluation of the ‎extended mind thesis.‎. (shrink)

According to the Best System Account of lawhood, laws of nature are theorems of the deductive systems that best balance simplicity and strength. In this paper, I advocate a different account of lawhood which is related, in spirit, to the BSA: according to my account, laws are theorems of deductive systems that best balance simplicity, strength, and also calculational tractability. I discuss two problems that the BSA faces, and I show that my account solves them. I also use my account (...) to illuminate the nomological character of special science laws. (shrink)

Instances of the law of large numbers are used to model many different physical systems. In this paper, I argue for a particular interpretation, of those instances of that law, which appeals to typicality. As I argue, the content of that law, when used to model physical systems, is that the probability of an event typically—rather than probably—approximates the frequency with which that event occurs.

I present and explain the Bohmian account of collapse in quantum mechanics.

Evidential Decision Theory is flawed, but its flaws are not fully understood. David Lewis (1981) famously charged that EDT recommends an irrational policy of managing the news and “commends the ostrich as rational”. Lewis was right, but the case he appealed to—Newcomb’s Problem—does not demonstrate his conclusion. Indeed, decision theories other than EDT, such as Committal Decision Theory and Functional Decision Theory, agree with EDT's verdicts in Newcomb’s Problem, but their flaws, whatever they may be, do not stem from any (...) ostrich-like recommendations. We offer a new case which shows that EDT mismanages the news, thus vindicating Lewis’s original charge. We argue that this case reveals a flaw in the “Why ain’cha rich?” defense of EDT. We argue further that this case is an advance on extant putative counterexamples to EDT. (shrink)

ABSTRACTCurrent evolutionary models of revenge focus on its complex deterrent functions. Nevertheless, there are some retaliatory behaviors in nonhuman animals that do not appear to have a deterren...

There have been several recent attempts to think about psychological kinds as homologies. Nevertheless, there are serious epistemic challenges for individuating homologous psychological kinds, or cognitive homologies. Some of these challenges are revealed when we look at competing claims of cognitive homology. This paper considers two competing homology claims that compare human anger with putative aggression systems of nonhuman animals. The competition between these hypotheses has been difficult to resolve in part because of what I call the boundary problem: boundaries (...) between instances of psychological kinds (e.g., anger and fear) cannot be directly observed. Thus, there are distinctive difficulties for individuating psychological kinds across lineages. I draw four conclusions from this case study: First, recent evidence from the neuroscience of fear suggests that one of the proposed homologies involves a straightforward conflation of anger and fear. Second, this conflation arises because of the boundary problem. Third, there is an implicit constraint on the operational criteria that is easy to overlook in the psychological case. In this case, ignoring the constraint is part of the problem. Fourth, this is a clear case in which knowledge of homology cannot be accumulated piecemeal. Identifying homologs of human anger requires identifying homologs of fear. (shrink)

I propose an account of possible worlds. According to the account, possible worlds are pluralities of sentences in an extremely large language. This account avoids a problem, relating to the total number of possible worlds, that other accounts face. And it has several additional benefits.

Commentary on the European Court of Human Rights judgment in Haas v Switzerland.

It is often assumed that theorizing in terms of natural properties is more objectively valuable than theorizing in terms of non-natural properties. But this assumption faces an explanatory challenge: explain the greater objective value of theorizing in terms of natural properties. In this paper, I answer that challenge by proposing and exploring three different accounts of the objective value of naturalness. Two appeal to constitutive natures: it is part of the constitutive nature of explanation, or of objective value, that theorizing (...) in terms of natural properties is more objectively valuable. The third appeals to the theoretical role that naturalness plays. (shrink)

A traditional social scientific divide concerns the centrality of the interpretation of local understandings as opposed to attending to relatively general factors in understanding human individual and group differences. We consider one of the most common social scientific variables, race, and ask how to conceive of its causal power. We suggest that any plausible attempt to model the causal effects of such constructed social roles will involve close interplay between interpretationist and more general elements. Thus, we offer a case study (...) that one cannot offer a comprehensive model of the causal power of racial categories as social constructions without careful attention both to local meanings and more general mechanisms.

In this paper I will analyze Lev (Leo) Tolstoy’s arguments for Christian Anarchism which is found in his book Царство Божие Внутри Вас (tr. The Kingdom of God is Within You). By analyzing his arguments, I will present why Tolstoy believes that Christianity inevitably leads to a belief and practice of pacifism and anarchism. In other words, Tolstoy is attempting to prove that capitalism and governments of any kind are incompatible with Christian ethics. Thus, what this paper attempts to achieve (...) is to analyze whether Tolstoy is correct in his claims: does capitalism, as an economic system, and governmental authority conflict with Christian morality. I am not interested in proving that capitalism and governments are, in general, morally bad, or wrong systems but rather or not they contradict Christian doctrine. Many commentators have mentioned that Tolstoy’s philosophical works and arguments are ‘naïve’ and or ‘lacking.’ However, in this paper, I will prove that this is not entirely the case. That in fact, Tolstoy’s philosophical arguments are highly focused and more complex than what people present them to be. He is also no lesser of a philosopher for having no formal or academic philosophical education. For we should not restrict the title of ‘philosopher’ for only those who belong in academia or the institutions. (shrink)

The use of military force abroad is a significant part of some states’ counter-terrorist efforts. Can these operations be ethically justified? This paper considers whether the underlying principles that philosophers have put forward to justify humanitarian interventions (which may underlie the international norm of the responsibility to protect (R2P)) can also give support for foreign counter-terrorist interventions of this sort. While it finds that the limits to international action that are imposed by the need to respect state sovereignty do not (...) rule out counter-terrorist interventions, it urges caution in supporting an international norm permitting them. Because such a norm would be open to manipulation and abuse, it may be preferable to discourage appealing to it in order to justify military counter-terrorism. (shrink)

In this chapter, we explore some ways in which reasoning based on mysticism can be rational, focusing on the episode “The Fortuneteller,” in which Aang, Katara, and Sokka save a village from a volcanic eruption. Throughout this episode, Sokka advocates a purely empirical approach to reasoning. The villagers, however, believe that no source of knowledge is more reliable than Aunt Wu, the local fortuneteller. At several points in the episode, Sokka claims that the villagers’ reliance on Aunt Wu is irrational. (...) The villagers claim otherwise: since Aunt Wu has never led them astray, it is rational to rely on her. As we will see, the villagers are right. Their approach to reasoning – based on Aunt Wu’s fortunetelling – is more rational than it initially seems to be. Roughly put, despite their belief in the mystical, the villagers behave in accord with a standard philosophical theory of rational decision-making, a theory of what makes some decisions rational and other decisions not. So Sokka is wrong to claim that the villagers’ reliance on Aunt Wu is irrational. The villagers behave quite rationally. (shrink)

I argue that given the persistent injustice present within the Prison Industrial Complex in the United States, many incarcerated individuals would be justified in attempting to escape and that these prison breaks may qualify as acts of civil disobedience. After an introduction in section one, section two offers a critique of the classical liberal conception of civil disobedience envisioned by John Rawls. Contrary to Rawls, I argue that acts of civil disobedience can involve both violence and evasion of punishment, both (...) of which are necessary components of prison breaks. In section three I outline the broad circumstances in which escape attempts would be justified, which are when individuals have either been incarcerated on unjust grounds (such as coercive plea bargains, draconian laws, or institutionalized discrimination) or when individuals are subject to inhumane conditions within prison (such as physical or sexual abuse, inadequate medical care, and overcrowding). Although this framework is formulated with the U.S. criminal justice system in mind, it is potentially applicable to other instances of incarceration if they’re similarly unjust such as prisons in other countries, migrant detention centers, or psychiatric wards. I then outline four requirements which must be met for these prison breaks to qualify as civil disobedience. First, escape must be attempted as a last resort. Second, violence and other law-breaking must be reasonable, meaning it is done with precision, discretion, and proportion. Third, escapees hold the burden of proving they have been subject to injustice. Fourth and finally, the act of escape must contain other key components of civil disobedience such as persuasion, communication, and publicity, which will most likely be accomplished via coordination with non-incarcerated individuals. In section four I address the distinction between prison reform and abolition. (shrink)

Since its proposal in 1984, Derek Parfit’s ‘Non-Identity Problem’ has significantly influenced how social choice theorists understand existential harms and benefits. The ‘problem’ raises the question of whether parents act wrongly when they choose to create a child with a life barely worth living. It suggests that if the alternatives would have either resulted in a life not worth living or non-existence, then the parents are not liable for moral criticism. This article challenges Parfit’s premise by advocating for a Minimal (...) Concern Clause that is generated through the parental relation. The Clause operates under the assumption that non-existence is not a valanced experiential state and is thus not comparable to any positive state of existence. The argument unfolds in two main steps: firstly, it disputes the premise in Same-Number Cases by proposing an alternative semantic distinction between objects of reference, particularly, the status of a merely possible person. Secondly, it contends that in Different-Number Cases, parents are obligated to exercise minimal prudence under conditions of uncertainty, and that the moral weight of the Minimal Concern Clause must be compounded to reflect the replicable nature of procreation.

People increasingly form beliefs based on information gained from automatically filtered Internet ‎sources such as search engines. However, the workings of such sources are often opaque, preventing ‎subjects from knowing whether the information provided is biased or incomplete. Users’ reliance on ‎Internet technologies whose modes of operation are concealed from them raises serious concerns about ‎the justificatory status of the beliefs they end up forming. Yet it is unclear how to address these concerns ‎within standard theories of knowledge and justification. (...) To shed light on the problem, we introduce a ‎novel conceptual framework that clarifies the relations between justified belief, epistemic responsibility, ‎action, and the technological resources available to a subject. We argue that justified belief is subject to ‎certain epistemic responsibilities that accompany the subject’s particular decision-taking circumstances, ‎and that one typical responsibility is to ascertain, so far as one can, whether the information upon which ‎the judgment will rest is biased or incomplete. What this responsibility comprises is partly determined by ‎the inquiry-enabling technologies available to the subject. We argue that a subject’s beliefs that are ‎formed based on Internet-filtered information are less justified than they would be if she either knew how ‎filtering worked or relied on additional sources, and that the subject may have the epistemic ‎responsibility to take measures to enhance the justificatory status of such beliefs.‎.

Positing group level obligations has come under attack from concerns relating to agency as a necessary requirement for obligation bearing. Roughly stated, the worry is that since only agents can have moral obligations, and groups are not agents, groups cannot have moral obligations. The intuition behind this constraint is itself based on the ability requirement of 'ought implies can': in order for a group to have an obligation it must have the ability to perform an action, but only agents can (...) have abilities. This paper argues that from accounts of shared agency we can develop a concept of joint ability, undermining the problem of agency for group obligations. (shrink)

In ‘Treating Adolescents Differently’, Skelton, Black, and Forsberg develop their wellbeing-based justification of the asymmetrical treatment of adolescent consent and refusal in the context of health care to justify the differential and paternalistic treatment of adolescents more generally. The core of the Skelton, Black, and Forsberg’s view is a variabilist theory of what is fundamentally and non-instrumentally prudentially good for adolescents, which includes the prudential value of what they call shielding—or the value of being insulated from full responsibility for their (...) choices. This theory of wellbeing, they argue, explains why adolescents may be treated differential and paternalistically in numerous domains. It is good for them to be shielded because it allows for a variety of freedom from making certain kinds of decisions in the absence of a safety net provided by others in supportive and caring relationships. Skelton, Black, and Forsberg argue that their account of the justification of differential and paternalistic treatment of adolescents has attractive implications for a range of cases and holds up well in the face of philosophical criticism.

I argue that the evolutionary history of anger has substantive implications for normative ethics. In the process, I develop an evolutionary account of anger and its influence on action. First, I consider a prominent argument by Peter Singer and Joshua Greene. They conclude that evolutionary explanations of human cooperation debunk – or undercut the evidential value of – the moral intuitions supporting duty ethics (as opposed to utilitarian or consequentialist ethics). With this argument they aim to defend consequentialist theories. However, (...) their argument also threatens to debunk intuitions that support consequentialist theories. I give a novel argument that overcomes this difficulty. Specifically, I offer an evolutionary story about anger that can explain retributive, duty-oriented intuitions concerning punishment. This explanation debunks these intuitions (and not others) by showing that they were selected for their biological consequences rather than their accuracy (concerning duties to punish). I develop this explanation by raising and resolving three additional problems. First, prominent evolutionary explanations of retributive motives fail because they appeal to models that apply only to organisms with strategic insight. To mitigate this problem, I explain the existence of a retributive-like motive in rodents by appealing to an economic model of resource competition, which applies to organisms without strategic insight. Second, I show that human anger was shaped by resource competition of this kind. To do so, I develop evidential criteria to determine when psychological systems in different species share common evolutionary origins. I deploy these criteria to argue that human anger and the retributive motive in rodents derive from the same ancestral trait. Finally, the continuity of anger across human and nonhuman animals stands in tension with the idea that anger causes purposive behavior like retribution or retaliation. I argue that differences between the angry behaviors of human and nonhuman animals are differences in degree and not in kind. In the end, this evolutionary story both explains and undermines retributive intuitions, but not in the straightforward way that Singer and Greene suppose. (shrink)
