Perhaps the question “What is philosophy?” can only be posed late in life, when old age has come, and with it the time to speak in concrete terms. It is a question one poses when one no longer has anything to ask for, but its consequences can be considerable. One was asking the question before, one never ceased asking it, but it was too artificial, too abstract; one expounded and dominated the question, more than being grabbed by it. There are (...) cases in which old age bestows not an eternal youth, but on the contrary a sovereign freedom, a pure necessity where one enjoys a moment of grace between life and death, and where all the parts of the machine combine to dispatch into the future a trait that traverses the ages: Turner, Monet, Matisse. The elderly Turner acquired or conquered the right to lead painting down a deserted path from which there was no return, and that was no longer distinguishable from a final question. In the same way, in philosophy, Kant’s Critique of Judgment is a work of old age, a wild work from which descendants will never cease to flow.We cannot lay claim to such a status. The time has simply come for us to ask what philosophy is. And we have never ceased to do this in the past, and we already had the response, which has not varied: philosophy is the art of forming, inventing, and fabricating concepts. But it was not only necessary for the response to take note of the question; it also had to determine a time, an occasion, the circumstances, the landscapes and personae, the conditions and unknowns of the question. One had to be able to pose the question “between friends” as a confidence or a trust, or else, faced with an enemy, as a challenge, and at the same time one had to reach that moment, between dog and wolf, when one mistrusts even the friend. Gilles Deleuze was professor of philosophy at the University of Paris VIII, Vincennes-St.-Denis, until his retirement in 1987. Among his books translated into English are the two-volume Capitalism and Schizophrenia , the two-volume Cinema , The Logic of Sense , and Expressionism in Philosophy: Spinoza . Daniel W. Smith is a doctoral candidate in philosophy at the University of Chicago. He is at work on a study of the philosophy of Deleuze, and is translating Deleuze’s Francis Bacon: Logique de la sensation.

In some musical genres, professional performers play live shows many times a week. Arduous touring schedules bring encounters with wildly diverse audiences across many different performance ecologies. We investigate the kinds of creativity involved in such repeated live performance, kinds of creativity that are quite unlike songwriting and recording, and examine the central factors that influence musicians’ wellbeing over the course of a tour. The perspective of the professional musician has been underrepresented in research on relations between music and wellbeing, (...) with little attention given to the experience of touring. In this case study, we investigate influences on positive and negative performance experiences for the four professional musicians of Australian pop/rock band Cloud Control. Geeves conducted intensive cognitive ethnographic fieldwork with Cloud Control members over a two-week national Australian tour for their second album, Dream Cave (2013). Adapting a Grounded Theory approach to data analysis, we found the level of wellbeing musicians reported and displayed on tour to be intimately linked to their creative performance experiences through the two emergent, overarching and interdependent themes of Performance Headspace (PH) and Connection with Audience (CA). We explore these themes in detail and provide examples to demonstrate how PH and CA can feed off each other in virtuous ways that positively shape musicians’ wellbeing, or loop in vicious ways that negatively shape musicians’ wellbeing. We argue that their creative practice, in thus re-enacting musical performance afresh in each venue’s distinctive setting, emerges within unique constraints each night, and is in a sense a co-creation of the crowd and the band.

Contemporary natural-language semantics began with the assumption that the meaning of a sentence could be modeled by a single truth condition, or by an entity with a truth-condition. But with the recent explosion of dynamic semantics and pragmatics and of work on non- truth-conditional dimensions of linguistic meaning, we are now in the midst of a shift away from a truth-condition-centric view and toward the idea that a sentence’s meaning must be spelled out in terms of its various roles in (...) conversation. This communicative turn in semantics raises historical questions: Why was truth-conditional semantics dominant in the first place, and why were the phenomena now driving the communicative turn initially ignored or misunderstood by truth-conditional semanticists? I offer a historical answer to both questions. The history of natural-language semantics—springing from the work of Donald Davidson and Richard Montague—began with a methodological toolkit that Frege, Tarski, Carnap, and others had created to better understand artificial languages. For them, the study of linguistic meaning was subservient to other explanatory goals in logic, philosophy, and the foundations of mathematics, and this subservience was reflected in the fact that they idealized away from all aspects of meaning that get in the way of a one-to-one correspondence between sentences and truth-conditions. The truth-conditional beginnings of natural- language semantics are best explained by the fact that, upon turning their attention to the empirical study of natural language, Davidson and Montague adopted the methodological toolkit assembled by Frege, Tarski, and Carnap and, along with it, their idealization away from non-truth-conditional semantic phenomena. But this pivot in explana- tory priorities toward natural language itself rendered the adoption of the truth-conditional idealization inappropriate. Lifting the truth-conditional idealization has forced semanticists to upend the conception of linguistic meaning that was originally embodied in their methodology. (shrink)

In this dissertation, I explore the work of Donald Davidson, reveal an inconsistency in it, and resolve that inconsistency in a way that complements a debate in philosophy of science. In Part One, I explicate Davidson's extensional account of meaning; though not defending Davidson from all objections, I nonetheless present his seemingly disparate views as a coherent whole. In Part Two, I explicate Davidson's views on the dualism between conceptual schemes and empirical content, isolating four seemingly (...) different arguments that Davidson makes against the dualism; I demonstrate that, though the arguments fail, each is ultimately meant to rely on his account of meaning. ;In Part Three, I show that Davidson's extensional account of meaning gives rise to the analytic-synthetic distinction, while simultaneously needing to reject it. I then propose a resolution to Davidson's dilemma. Rather than treating interpretation of meaning as continuous with the holistic enterprise of science, as Quine treats translation, one should treat it as conceptually prior to science, as Kant treats epistemology. Nonetheless I recognize four reasons why Davidson himself would reject doing so. I therefore propose a view called 'transcendental semantics', based on Davidson's, that accepts my resolution. Further, transcendental semantics, like Kant's own transcendental idealism, posits a single conceptual scheme; nonetheless Kant's is concerned with Newtonian physics, transcendental semantics' with interpretation. ;Finally, in Part Four, I show how positing such a scheme allows transcendental semantics to complement a promising neo-Carnapian account of theory confirmation in science proposed by Michael Friedman. Scientists are first and foremost interpreters, a fact that allows transcendental semantics to help Friedman establish the possibility of rational continuity through scientific revolutions. In fact, transcendental semantics, by complementing Friedman's project, reunites two of Carnap's own concerns, philosophy of language and philosophy of science. I conclude that philosophy of language without philosophy of science is empty , while philosophy of science without philosophy of language is blind. (shrink)

Davidson has famously argued that conceptual relativism, which, for him, is based on the content-scheme dualism, or the “third dogma” of empiricism, is either unintelligible or philosophically uninteresting and has accused Quine of holding onto such a dogma. For Davidson, there can be found no intelligible ground for the claim that there may exist untranslatable languages: all languages, if they are languages, are in principle inter-translatable and uttered sentences, if identifiable as utterances, are interpretable. Davidson has also (...) endorsed the Quinean indeterminacy-underdetermination distinction. The early Quine, as well as the later Quine, believe that the indeterminacy of translation casts serious doubt on the existence of facts of the matter about correct translation between languages. In this paper, I will argue that Quine cannot be the target of Davidson’s argument against conceptual relativism, and that Davidson’s argument is in conflict, among others, with his endorsement of the Quinean indeterminacy-underdetermination distinction. I will show how this conflict results in a radical departure from Quine with respect to the matter of factualism about fine-grained meanings. (shrink)

Given W.V. Quine’s and Donald Davidson’s extensive agreement about much of the philosophy of language and mind, and the obvious methodological parallels between Quine’s radical translation and Davidson’s radical interpretation, many—including Quine and Davidson—are puzzled by their occasional disagreements. I argue for the importance of attending to these disagreements, not just because doing so deepens our understanding of these influential thinkers, but because they are in fact the shadows thrown from two distinct conceptions of philosophical inquiry: Quine’s (...) “naturalism” and what I call Davidson’s “humanism.” The clash between Quine and Davidson thus provides valuable insight into the history of analytic naturalism and its malcontents.

Burton Dreben taught a generation of scholars the value of closely attending to the recent philosophical past. But the few papers he authored do little to capture his philosophical voice. In this article, I turn instead to an unpublished transcript of Dreben in conversation with his contemporaries. In addition to yielding insights into a transitional period in W.V. Quine’s and Donald Davidson’s thought, I argue that this document showcases Dreben in his element, revealing the way that he shaped the (...) views of key analytic philosophers. More broadly, I argue that by writing conversationalists like Dreben into our histories we can capture the collaborative nature of philosophy. (shrink)

W. V. Quine’s “Two Dogmas of Empiricism”, first published in 1951, is one of the most influential articles in the history of analytic philosophy. It does not just question central semantic and epistemological views of logical positivism and early analytic philosophy, it also marks a momentous challenge to the ideas that conceptual analysis is a main task of philosophy and that philosophy is an a priori discipline which differs in principle from the empirical sciences. These ideas dominated early analytic philosophy, (...) but similar views are to be found in the Kantian tradition, in phenomenology and in philosophical hermeneutics. In questioning this consensus from the perspective of a radical empiricism, Quine’s article has had a sustained and lasting impact across all these philosophical divisions. Quine himself moved from the abandonment of the analytic/synthetic distinction to a thoroughgoing naturalism, and many analytic philosophers have followed his lead. The current collection differs from other anthologies devoted to Quine in two respects. On the one hand, it focuses on his attack on analyticity, apriority and necessity; on the other, it considers implications of that attack that far transcend the limits of Quine scholarship, and lie at the heart of the current self-understanding of philosophy. The contributors include both opponents and proponents of the dichotomies attacked by Quine. Furthermore, they include both eminent figures such as Boghossian, Burge, and Davidson, and up and coming younger philosophers. (shrink)

In the early twentieth century, Uchiyama Gudō, Seno’o Girō, Lin Qiuwu, and others advocated a Buddhism that was radical in two respects. Firstly, they adopted a more or less naturalist stance with respect to Buddhist doctrine and related matters, rejecting karma or other supernatural beliefs. And secondly, they held political and economic views that were radically anti-hegemonic, anti-capitalist, and revolutionary. Taking the idea of such a “radical Buddhism” seriously, A Buddha Land in This World: Philosophy, Utopia, and Radical Buddhism asks (...) whether it is possible to develop a philosophy that is simultaneously naturalist, anti-capitalist, Buddhist, and consistent. Rather than a study of radical Buddhism, then, this book is an attempt to radicalize it. The foundations of this “radicalized radical Buddhism” are provided by a realist interpretation of Yogācāra, elucidated and elaborated with some help from thinkers in the broader Tiantai/Tendai tradition and American philosophers Donald Davidson and W.V.O. Quine. A key implication of this foundation is that only this world and only this life are real, from which it follows that if Buddhism aims to alleviate suffering, it has to do so in this world and in this life. Twentieth-century radical Buddhists (as well as some engaged Buddhists) came to a similar conclusion, often expressed in their aim to realize “a Buddha land in this world.” Building on this foundation, but also on Mahāyāna moral philosophy, this book argues for an ethics and social philosophy based on a definition of evil as that what is or should be expected to cause death or suffering. On that ground, capitalism should be rejected indeed, but utopianism must be treated with caution as well, which raises questions about what it means – from a radicalized radical Buddhist perspective – to aim for a Buddha land in this world.

According to the philosophical tradition, translation is successful when one has substituted words and sentences from one language with those from another by cross-linguistic synonymy. Moreover, according to the orthodox view, the meaning of expressions and sentences of languages are determined by their basic or systematic role in a language. This makes translating normative and evaluative discourse puzzling for two reasons. First, as languages are syntactically and semantically different because of their peculiar cultural and historical influences, and as values and (...) norms differ across cultures, it is unlikely that languages will have synonymous evaluative and normative expressions. If translation is only successful by cross-linguistic synonymy, it would seem that we will not be able to translate the value theoretic claims of persons from radically different cultures. But it is with such persons that dialogue on evaluative matters is imperative, to resolve ethical and axiological differences that could be the root of conflict. Second, as the orthodox account of meaning renders it linguistically relative, it is unlikely that expressions across languages will be cross-linguistically synonymous. Thus, on the Orthodox account of translation, translation is indeterminate (as W.V.O. Quine has argued) or impossible (as Jacques Derrida has argued). In this dissertation I argue for a novel theory of meaning and translation based on innovations in the translation studies literature and my prior work in cross cultural research, which I call Text-Type Semantics or TTS. TTS explains how translation is successful while affirming radical cultural and linguistic diversity. It treats disciplinary concerns as the neutral criteria to calibrate translation. On the basis of TTS I argue that we need what I call the “Quasi-Indexical” account of thick and thin concepts (or QI) to translate normative and evaluative discourse. I argue that QI and TTS succeed where competing accounts in the moral semantics literature (such as Non-Analytic Naturalism and Expressivism) fail. The argument also shows that the relativization of truth (in philosophy and beyond) to languages and cultures is mistaken. (shrink)

One of the leading exponents of W's ideas on the language games of inner and outer (the `Two Selves' operation of our personality or intentionality or EP etc.) is the prolific Daniel Hutto (DH). His approach is called `Radical Enactivism' and is well explained in numerous recent books and papers (see my review of Radicalizing Enactivism) and a new one is appearing as I write (Evolving Enactivism). It is a development of or version of the Embodied Mind ideas now current (...) and, cleansed of its jargon, it is a straightforward extension of W's 2nd and 3rd period writings (though Hutto seems only intermittently aware of this). -/- Unfortunately, in 2006 Hutto had not yet arrived at his Radical Enactivism, so much time is wasted on McDowell and Brandom and of course none of them to this day have totally digested the later W and his prescient analysis of automatic behavior and the two systems of thought - so fully in tune with contemporary research. Nor is there any discussion of Searle's groundbreaking and completely Wittgensteinian (unwittingly) disquisitions on the Construction of Social Reality. Thus, his chapters 5 and 6 on Realism and Idealism etc., though superb for 2002, need a complete rewrite from a modern two systems viewpoint and I provide a start on that in my review. Much time is wasted on Davidson and Williams, etc. but one can endure them for Hutto's brilliant analyses and the frequent quotes from W. The last chapter gives his critic Rupert Read the counterblast he deserves and permits a slight update to 2006. Overall a lovely book and I eagerly await the third edition which I hope will ensue. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019).

O exame ultrassonográfico é uma ferramenta diagnóstica de grande relevância na rotina veterinária, uma vez que, apresenta ampla difusão entre os atendimentos de animais e permite a avaliação de órgãos e estruturas de forma não invasiva, segura e rápida, auxiliando na determinação de diversas afecções, levando ao tratamento adequado e contribuindo de forma positiva no prognóstico do paciente. Atualmente, em muitos casos, a avaliação testicular não faz parte da rotina ultrassonográfica em exames de ênfase abdominal, devido à sua localização anatômica (...) no escroto, podendo assim levar ao diagnóstico limitado e ao tratamento inadequado do paciente quando na ausência da avaliação dos testículos, posto que diversas são as afecções testiculares que podem acometer cães e que apresentam características ultrassonográficas de fácil detecção. Dentre as principais alterações observadas por meio da ultrassonografia, os casos de orquite, criptorquidismo, torção e também neoformações neoplásicas testiculares correspondem à maior casuística, sendo o método ultrassonográfico um exame com 98% a 100% de sensibilidade e acurácia para diagnóstico destas. Dessa forma, o objetivo deste artigo de revisão bibliográfica é elucidar a importância da avaliação testicular em exames ultrassonográficos de rotina, discorrendo inicialmente sobre os aspectos anatômicos e ultrassonográficos, e posteriormente acerca das afecções mais comumente diagnosticadas na rotina veterinária, apresentando ainda as alterações ultrassonográficas causadas no parênquima testicular.

Currently, in many cases, testicular evaluation is not part of the ultrasound evaluation in exams with abdominal emphasis, due to its anatomical location in the scrotum, which can lead to limited diagnosis and inadequate treatment of the patient in the absence of ultrasound evaluation of the testicles, since there are several testicular affections that can affect dogs and that present ultrasonographic characteristics that are easily detected. Among the main alterations observed during ultrasonographic exams, cases of orchitis, cryptorchidism, torsion and also testicular neoplastic neoformations correspond to the largest sample, with the ultrasonographic method being an exam with 98% to 100% sensitivity and accuracy for their diagnosis. Thus, the aim of this literature review article is to elucidate the importance of testicular evaluation in routine ultrasound examinations, initially discussing the anatomical and ultrasound aspects, and later on the most commonly diagnosed conditions in the veterinary routine, also presenting the ultrasound changes caused in the testicular parenchyma.

The article considers pros and cons for a theoretic-measurement analogy, proposed by some philosophers as an illustration of semantic indeterminacy. Within this analogy ascribing of meanings to a certain linguistic expressions is compared with attribution of numbers according to a certain theory of measurement. Donald Davidson used this analogy in order to extend W.V.O. Quine's thesis of indeterminacy of translation to the interpretation of all human behavior. In other words, not only linguistic meanings, but all mental states are considered (...) as indeterminate. The article explains the failure of some counter-arguments put forward against Davidson's use of this analogy and against the thesis of indeterminacy on the whole. Particularly, instrumentalist version of the analogy is rejected for there is no direct relation between indeterminacy and underdetermination of theories by empirical evidences. The article concludes that the semantic indeterminacy is largely based on indeterminacy of rationality. (shrink)

RESUMO A bovinocultura sempre esteve atrelada ao desenvolvimento do Brasil e, pensando no avanço, as exigências da máxima eficiência nos sistemas de criação foi pautada na forma de como conseguir realizar a reprodução de bovinos com ênfase na eficiência econômica e reprodutiva. O objetivo deste trabalho é elucidar as principais biotecnologias que auxiliam na maior produtividade reprodutiva de bovinos. Dessa forma, o estudo foi realizado usando artigos do banco de dados do Google acadêmico e SciELO, além de livros do acervo (...) pessoal e sites oficiais. Com o manejo reprodutivo aplicado na bovinocultura, é possível identificar pontos a serem melhorados e implantação de práticas que auxiliam no incremento da eficiência reprodutiva como a estação de monta, que concentra a fertilização dos animais em uma determinada época do ano, o uso do índice de escore corporal, o qual consegue determinar a viabilidade da vaca a ser fertilizada, e a identificação da idade a puberdade, na qual a novilha com 60% de peso vivo quando adulta pode estar apta para reprodução, indicando que a nutrição é um fator importante para reduzir o intervalo entre partos, bem como na indução da precocidade, que ainda pode ser maximizada por uso de bioestimuladores. Assim como a implantação do uso de biotecnologias, que podem adicionar aos planteis, indivíduos geneticamente superiores, saudáveis e eficientes. Dentre as biotecnologias, a inseminação artificial é a mais usada no Brasil, com capacidade de fertilizar vacas com sêmen de touros de genética superior, nacional ou importado. Podem ser citadas ainda as técnicas de transferência de embriões e produção in vitro de embriões como tecnologias a serviço do desenvolvimento da eficiência reprodutiva. A utilização de protocolos hormonais no ciclo estral objetiva a sincronização do estro das vacas para facilitar o emprego das biotecnologias. São vários os protocolos usados para essa finalidade, sendo Ovsynch a base de GnRH e prostaglandina com até 50% de eficácia, protocolos à base de estradiol e progesterona com eficácia de até 86,6%, e protocolos que usam gonadotrofina coriônica equina (eCG), indicados para animais magros por condicionar maior diâmetro folicular, o qual é relacionado com aumento na taxa de prenhez. Dessa maneira, as práticas e tecnologias citadas neste estudo são usadas na reprodução assistida de bovinos. PALAVRAS-CHAVE: Criopreservação. Estro. Gestação. Hipófise. Nutrição. ABSTRACT Cattle farming has always been linked to Brazil’s development and, thinking about advancement, the requirements for maximum efficiency in breeding systems was based on how to achieve the reproduction of cattle with an emphasis on economic and reproductive efficiency. The objective of this work is to elucidate the main biotechnologies that help in the greater reproductive productivity of cattle. Thus, the study was done using articles from the Academic Google and SciELO databases, as well as books from the personal collection and official websites. With the reproductive management applied in cattle farming, it is possible to identify points to be improved and implement practices that help to increase reproductive efficiency, such as the breeding season, which concentrates the fertilization of animals at a certain time of year, use of the body score index, which can determine the viability of the cow to be fertilized, identification of age at puberty, in which the heifer with 60% live weight as an adult may be suitable for reproduction, indicating that nutrition is an important factor in reducing the interval between births, as well as in inducing precocity, which can still be maximized by the use of biostimulators. As well as the implementation of the use of biotechnology, which can add genetically superior, healthy and efficient individuals to the breeding stock. Among the biotechnologies, artificial insemination is the most used in Brazil, with the capacity to fertilize cows with superior genetic bull semen, whether national or imported. Embryo transfer techniques and in vitro embryo production can also be cited as technologies in the service of the development of reproductive efficiency. The use of hormonal protocols in the estrous cycle aims at synchronizing the estrus of cows to facilitate the use of biotechnologies. There are several protocols used for this purpose, with Ovsynch being based on GnRH and prostaglandin with up to 50% efficacy, protocols based on estradiol and progesterone with efficacy of up to 86.6%, and protocols that use equine chorionic gonadotropin (eCG), indicated for lean animals because they condition larger follicular diameter, which is related to an increase in the pregnancy rate. Thus, the practices and technologies mentioned in this study can help the assisted reproduction of cattle. KEYWORDS: Cryopreservation. Estro. Gestation. Hypophysis.

This papers assesses the possibility of an empiricism without dogmas. It advances an argument against Quine's conceptions regarding philosophy of language and tries to expand the Davidsonian semantics and epistemic program.

Blackburn and Searle have argued that Quine‘s thesis of the indeterminacy of translation results in a denial of the sort of first-person authority that we commonly concede we have over our mental and semantical content. For, the indeterminacy thesis implies that there is no determinate meaning to know at all. And, according to Quine, the indeterminacy holds at home too. For Blackburn, Quine must constrain the domain of indeterminacy to the case of translation only. Searle believes that Quine has no (...) other choice but to give up on his behaviorism. Hylton, however, has attempted to defend Quine against these objections, by arguing that Quine‘s naturalistic claim that speaking a language is nothing but possessing certain dispositions to act in specific ways would enable him to accommodate first-person authority. I will argue that the objections from Blackburn and Searle, as well as Hylton‘s solution, are all problematic when seen from within Quine‘s philosophy. I will introduce a sort of Strawsonian-Wittgensteinian conception of first-person authority and offer that it would be more than compatible with Quine‘s naturalistic philosophy. (shrink)

One of the leading exponents of W's ideas on the language games of inner and outer (the `Two Selves' operation of our personality or intentionality or EP etc.) is the prolific Daniel Hutto (DH). His approach is called `Radical Enactivism' and is well explained in numerous recent books and papers (see my review of Radicalizing Enactivism) and a new one is appearing as I write (Evolving Enactivism). It is a development of or version of the Embodied Mind ideas now current (...) and, cleansed of its jargon, it is a straightforward extension of W's 2nd and 3rd period writings (though Hutto seems only intermittently aware of this). Unfortunately in 2006 Hutto had not yet arrived at his Radical Enactivism, so much time is wasted on McDowell and Brandom and of course none of them to this day have totally digested the later W and his prescient analysis of automatic behavior-so fully in tune with contemporary research. Nor is there any discussion of Searle's groundbreaking and completely Wittgensteinian (unwittingly) disquisitions on the Construction of Social Reality. Thus his chapters 5 and 6 on Realism and Idealism etc., though superb for 2002, need a complete rewrite from a modern two systems viewpoint and I provide a start on that in my review. Much time is wasted on Davidson and Williams, etc. but one can endure them for Hutto's brilliant analyses and the frequent quotes from W. The last chapter gives his critic Rupert Read the counterblast he deserves and permits a slight update to 2006. Overall a lovely book and I eagerly await the third edition which I hope will ensue. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019).

The Indeterminacy of Translation and Radical Interpretation The indeterminacy of translation is the thesis that translation, meaning, and reference are all indeterminate: there are always alternative translations of a sentence and a term, and nothing objective in the world can decide which translation is the right one. This is a skeptical conclusion because what it … Continue reading The Indeterminacy of Translation and Radical Interpretation →.

This is a work in Kantian conceptual geography. It explores issues in analytic epistemology, philosophy of language, and metaphysics by appealing to theses drawn from Immanuel Kant's Critique of Pure Reason.

We argue that work on norms provides a way to move beyond debates between proponents of individualist and structuralist approaches to bias, oppression, and injustice. We briefly map out the geography of that debate before presenting Charlotte Witt’s view, showing how her position, and the normative ascriptivism at its heart, seamlessly connects individuals to the social reality they inhabit. We then describe recent empirical work on the psychology of norms and locate the notions of informal institutions and soft structures with (...) respect to it. Finally, we argue that the empirical resources enrich Witt’s ascriptivism, and that the resulting picture shows theorists need not, indeed should not, choose between either the individualist or structuralist camp.

In this paper I will consider a number of responses to the grounding problem for presentism. I don’t think that the grounding problem is a damning problem for the presentist (it seems to me that presentism has much more serious problems with cross-time relations and relativity). But each of the solutions comes at a cost, and some are much pricier than others. I will set out what I take these costs to be when I examine each response to the grounding (...) problem. (shrink)

The concept of metaphor as primarily a vehicle for conveying ideas, even if unusual ones, seems to me as wrong as the parent idea that a metaphor has a special meaning. I agree with the view that metaphors cannot be paraphrased, but I think this is not because metaphors say something too novel for literal expression but because there is nothing there to paraphrase. Paraphrase, whether possible or not, inappropriate to what is said: we try, in paraphrase, to say it (...) another way. But if I am right, a metaphor doesn't say anything beyond its literal meaning. This is not, of course, to deny that a metaphor has a point, nor that that point can be brought out by using further words.... My disagreement is with the explanation of how metaphor works its wonders. To anticipate: I depend on the distinction between what words mean and what they are used to do. I think metaphor belongs exclusively to the domain of use. It is something brought off by the imaginative employment of words and sentences and depends entirely on the ordinary meanings of those words and hence on the ordinary meanings of the sentences they comprise.

Recent work in the philosophy of biology argues that we must rethink the biological individual beyond the boundary of the species, given that a key part of our essential functioning is carried out by the bacteria in our intestines in a way that challenges any strictly genetic account of what is involved for the biological human. The gut is a kind of ambiguous other within our understanding of ourselves, particularly when we also consider the status of gastro-intestinal disorders. Hegel offers (...) us theoretical tools to describe and understand our relationship to our gut. His description of our selves as continually mediated through otherness is strikingly compatible with the kind of structure contemporary biology presents us with. His accounts of digestion and habit, contextualized by his logic, help point toward an understanding of selfhood as porous and yet still capable of being sufficiently unified for us to make sense of ourselves, one which allows us to acknowledge otherness within us while still having enough unity for agency.

A discussion of L.A. Paul's 'Transformative Experience' from an Author Meets Critics session at the 2015 Pacific APA.

When discussing the problem of evil, philosophers often distinguish between physical evil (harm caused within the natural world such as natural disasters, disease, and the like), and moral evil (harm caused by human agency). Mapping this traditional distinction is mapped onto the third section of Fichte’s The Vocation of Man would at first seem fairly straightforward: for Fichte, evil arising from nature occurs through “blind mechanism” and is unfree; in contrast, evil done by human beings arises out of free agency. (...) The answer may be more complicated, however, in two different ways. First, Fichte holds that nature is to be cultivated and controlled by human beings so that it is no longer a source of harm; this may imply that the continuing harm done by nature is the result of humans’ failure to have sufficiently tamed nature. In that case, some of the harm caused by nature may be attributable to free human causality and thus no longer be a clearcut instance of natural evil. Second, Fichte repeatedly states that those who fail to act morally and who fail to conform their wills to the moral law are still be in the power of the mechanisms of nature. Even though we must think of them as free, Fichte compares their actions to the operation of nature and its mechanism of necessity. By presenting a careful and nuanced Fichtean account of the traditional distinction between physical and moral evil, we can better appreciate how Fichte understood the meaning and scope of human responsibility.

This response focuses on Balibar’s method of thinking transindividuality through multiple figures, in their similarities as well as their productive differences. His essay ‘Philosophies of the Transindividual: Spinoza, Marx, Freud’ combines the three titular figures in order to better think the multifaceted idea of ‘classical’ transindividuality. Balibar’s method combines the three but nonetheless maintains their dissimilarities as real differences. This response attempts to test or apply that method in two ways. The first application links Balibar’s analysis of Freud’s hypnotic leader (...) with a theme Balibar does not here discuss: wonder’s connection to superstition in Spinoza. At the level of their effects, superstitious wonder and hypnosis are nearly identical transindividual processes which lead to affective mass formation. However, their causes are quite distinct. This response details the similar effects and different causes, then asks the question: does their difference render them irreconcilable or complementary? Given the prominent role Spinoza plays in Balibar’s work, and the strong overall equivalence of wonder and hypnosis, this first application of Balibar’s method of multiple combination likely presents a complementarity rather than a conflict. This response’s second application, attempting to integrate another figure into the transindividual multiple, presents greater difficulties: what role, if any, could Foucault play in Balibar’s transindividuality? With Foucault, the tensions or differences perhaps amount to fundamental and thoroughgoing incompatibilities. However, combining Foucault with ‘classical’ transindividuality potentially extends and deepens each. This response concludes with examples of these problematic tensions as well as possibly fruitful combinations. (shrink)

As part of a trend in modern cognitive science, cognitive linguist, George Lakoff, and philosopher, Mark Johnson claim to provide a biologically-based account of subsymbolic meaningful experiences. They argue that human beings understand objects by extrapolating from their sensory motor activities and primary perceptions. Lakoff and Johnson’s writings have generated a good deal of interest among scholars of Early China because they maintain that “our common embodiment allows for common stable truths.” Although there are many grounds on which Lakoff and (...) Johnson’s theories have been criticized, this essay focuses in particular on problems related to their schema of Self as Container. Lakoff and Johnson contend that there are no pure experiences outside of culture, while nevertheless arguing that the experience of being a closed-off container is “direct.” “The concepts OBJECT, SUBSTANCE and CONTAINER emerge directly,” they write. “We experience ourselves as entities, separate from the rest of the world—as containers with an inside and an outside.” By “emerge directly,” they do not mean emerging free of culture, but rather that some experiences within culture, specifically physical experiences, are more directly given than others. My study explores the pitfalls of presuming the “direct” experience of containment makes good sense of texts from Early China (ca. 500–100 B.C.E). (shrink)

This is a critical notice of Theodore Sider's book, _Four-Dimensionalism_.

This is an article on the metaphysics of Alvin Plantinga. It is from the Blackwell Companion to Metaphysics (2009).

Most direct reference theorists about indexicals and proper names have adopted the thesis that singular propositions about physical objects are composed of physical objects and properties.1 There have been a number of recent proponents of such a view, including Scott Soames, Nathan Salmon, John Perry, Howard Wettstein, and David Kaplan.2 Since Kaplan is the individual who is best known for holding such a view, let's call a proposition that is composed of objects and properties a K-proposition. In this paper, I (...) will attempt to show that a direct reference view about the content of proper names and indexicals leads very naturally to the position that all singular propositions about physical objects are K-propositions.3 Then, I will attempt to show that this view of propositions is false. I will spend the bulk of the paper on this latter task. My goal in the paper, then, is to show that adopting the direct reference thesis comes at a cost problems the view has with problems such as opacity and the significance of some identity statements; it comes at even more of a cost).

Three professors reflect on the experience of creating a learning community of 22 students by linking courses in Literature and Ethics. The project demonstrates practical strategies for incorporating feminist scholarship and pedagogy into the core curriculum and for integrating core courses from diverse disciplines.

This is a paper in which I argue that problems of transworld identity and the truth in-truth at distinction are motivated by unhelpful pictures we have in mind while doing metaphysics.

Two major lines of argument support the notion that Hildegard of Bingen’s metaphysics is peculiarly gynocentric. Contra the standard commentary on her work, the focus is not on the notion of viriditas; rather, the first line of argument presents a specific delineation of her ontology, demonstrating that it is a graded hierarchy of beings, many of which present feminine aspects of the divine, and all of which establish the metaphysical notion of interpenetrability. The second line of argument specifically contrasts her (...) thought to that of Aquinas and Meister Eckhart, noting areas of similarity and difference. It is concluded that the visionary origins of Hildegard’s work may have to some extent precluded our understanding of it, and that her work merits consideration not only philosophically and theologically but from the standpoint of its early presentation of a gynocentric worldview.

Spinoza’s concepts of wonder, the imitation of affects, cheerfulness, and devotion provide the basis for a Spinozist aesthetics. Those concepts from his Ethics, when combined with his account of rituals and festivals in the Theological-Political Treatise and his Political Treatise, reveal an aesthetics of social affects. The repetition of ritualised participatory aesthetic practices over time generates a unique ingenium or way of life for a social group, a singular style which distinguishes them from the general political body. Ritual and the (...) imitation of affects explain why specific styles of art are associated with consistent styles of bodily modifications, clothing, and affects. This paper claims, not that already similar people flock to the same art, but rather, that immersion in the same art is what produces their similarity. Art (especially in the immersive, festival-like experience of live performance) can generate the affect of devotion, which intensifies in-group love, temporarily blocks affects of sadness, and focusses one intently on the aesthetic experience due to devotion’s connection to wonder. Cheerfulness shows that, through variation of aesthetic objects, art can cause pleasure without risking excess. In addition, while politics’ central affect is sad fear, aesthetically-united groups are bound by joyful affects. (shrink)

In this paper I argue that presentism has a problem accounting forthe truth of statements whose truth conditions seem to require therebe relations that hold between present and non-present objects. Imotivate the problem and then examine several strategies for dealingwith the problem. I argue that no solution is forthcoming, and thispresents a prima facie problem for presentism.

I argue that abstract objects cannot depend on God for their existence and nature.

In this paper we set out a view on which internalist proper basicality is secured by sensory experience.

Desde Descartes a epistemologia tem se baseado no conhecimento de primeira pessoa. Devemos começar, de acordo com a história usual, com o que é mais certo: o conhecimento de nossas próprias sensações e pensamentos. De uma maneira ou outra, progredimos então, se pudermos, para o conhecimento de um mundo externo objetivo. Há por fim uma passagem tênue ao conhecimento das outras mentes. Defendo uma total revisão desse quadro. Todo pensamento proposicional, quer positivo ou cético, sobre o interior ou sobre o (...) exterior, exige a posse do conceito de verdade objetiva, e esse conceito está acessível apenas a criaturas que estão em comunicação com outras. O conhecimento de outras mentes é, assim, básico para todo o pensamento. Mas esse conhecimento exige e supõe o conhecimento de um mundo compartilhado de objetos em um espaço e tempo comuns. Assim, a aquisição do conhecimento não é baseada em uma progressão do subjetivo para o objetivo; ele emerge holisticamente e é interpessoal desde o começo. (shrink)

Michelle’s thesis explores the extent to which a researcher could contribute to change by engaging leaders in conversations that might intensify commitment to or the direction of their actions around socio-environmental decline in Bermuda as a country historically organised in the tradition of an entrepreneurial for-profit enterprise. The framing of a space to reflect on highlighted the significance of time that led to the bricolage design of a heuristic device called a moon gate. Time, the keystone of the moon gate, (...) created a prism lighting up the twists and turns of kaleidoscopic images of the chaos of the markets and the creative diversity of human and nonhuman participants. She undertook a philosophical approach with her study of the contested space of time around sensitivity to maintaining a fulcrum point based on the wellbeing of people and planet. (shrink)

Spinoza rarely refers to art. However, there are extensive resources for a Spinozist aesthetics in his discussion of health in the Ethics and of social affects in his political works. There have been recently been a few essays linking Spinoza and art, but this essay additionally fuses Spinoza’s politics to an affective aesthetics. Spinoza’s statements that art makes us healthier (Ethics 4p54Sch; Emendation section 17) form the foundation of an aesthetics. In Spinoza’s definition, “health” is caused by external objects that (...) maintain our power to act in a variety of ways. Humans need such objects because our complex bodies constantly lose or consume many parts necessary to our overall functioning. Notably, Spinoza defines humans’ bodies through this complexity (2p13Sch), so health as maintenance of complexity is a distinctly human endeavor. Further, while art is not the only healthy activity, I argue that art is a particularly potent cure, which explains Spinoza’s otherwise opaque comment that music can cure melancholy (by which he meant a near-total inability to act, akin to death). Rather than only causing frivolous pleasures, art may be as essential to human flourishing as are other human beings in general; other people are “most useful” because of the variety of actions they make possible (4p35Cor & Sch1). Art’s production of a dizzying variety of affects is likewise most useful for health. -/- Having established how art in general affects the individual, I then explain the role of artists in shaping social groups. Artists use vivid and highly charged affective techniques, as do political sovereigns and religious prophets (TTP chapters 1-2 & 15-16). However, sovereigns and prophets are concerned exclusively with “morality,” defined by Spinoza as the use of affects (primarily based on fear and hope) to produce “obedience” in the generic multitude or people at large. An artist, however, rarely causes affects in the whole nation, affecting instead only a smaller niche or “sub-genre” of people. The affects produced in this group are also not identical to those used by sovereigns, since artists do not primarily deploy sad affects of hope and fear but instead use a wide variety of joyful affects. Further, in Spinoza’s analysis of ceremonies (TTP chapter 5), we see how small groups exposed to repeated ceremonies or social practices eventually develop new strengths which they lacked before. Repeated exposure to shared aesthetic “ceremonies” (e.g., live music performances) of the same sub-genre will over time create the capacity of new powers in the sub-genre of people, which distinguishes them from the masses. Spinoza says sovereigns forge a “second nature” for the generic people through affects; we can then affirm that smaller groups exposed to a distinct sub-genre of art can acquire a new “third nature” which will contain unique powers extending beyond healthy maintenance of their existing bodies. That is, art in general is necessary to flourish and remain whole (maintaining health), but it can also occasionally expand what one is to unforeseen heights (through specific artistic sub-genres).

Qual é a relação entre uma razão e uma ação quando a razão explica a ação, dando a razão do agente para fazer o que fez? Podemos chamar tais explicações de racionalizações, e dizer que a razão racionaliza a ação. Neste artigo quero defender a posição antiga — e de senso comum — de que a racionalização é uma espécie de explicação causal b. A defesa sem dúvida exige alguma reelaboração, mas não parece necessário abandonar a posição, como muitos autores (...) recentes insistem. (shrink)

This paper explores the role of generics in social cognition. First, we explore the nature and effects of the most common form of generics about social kinds. Second, we discuss the nature and effects of a less common but equally important form of generics about social kinds. Finally, we consider the implications of this discussion for how we ought to use language about the social world.

This work examines Michel Foucault’s critique of the present, through his analysis of our hidden but still active historical legacies. His works from the Eighties are the beginning of what he called a “genealogy of the desiring subject,” in which he shows that practices such as confession—in its juridical, psychological, and religious forms—have largely dictated how we think about our ethical selves. This constrains our notions of ethics to legalistic forbidden/required dichotomies, and requires that we engage in a hermeneutics of (...) the self which consistently fails to discover its imagined authentic self, or to find the happiness and freedom promised by contemporary ethics. In order to think the modern self in different terms, Foucault’s later works analyzed Classical and Hellenistic ethical sources, emphasizing their distance from today. He hoped doing so would allow us to rethink our current assumptions about ethical matters, the truth of oneself, and the relation to others. While Foucault’s genealogical descriptions critically diagnosed contemporary ills such as these, he did not prescribe a cure, preferring to let his readers experiment with new practices of their own design. This work attempts such an experiment, supplying concrete solutions to our ethical ills, in order to help us improve, as well as understand, our ethical selves. To that end, this work demonstrates that a form of subjectivity based on Benedict Spinoza’s ethical and political works avoids the pitfalls of modern ethics as diagnosed by Foucault. Additionally, the practices of the self found in Spinoza can be used to directly counter and displace each central element of “desiring subjectivity,” and thus supplies the kind of effective positive move which should follow after genealogical critique.

The essay "Rational Animals" is translated from the book: Donald Davidson: Subjective, Intersubjective, Objective. Oxford: Clarendon Press 2001, pp. 95-105.

O objetivo deste capítulo é analisar o conceito de informação como uma ação significativa em sistemas complexos adaptativos. A comunicação e a linguagem são vistas como sistemas complexos por Maturana & Varela (1994), cuja principal característica é a auto-organização. Para estes autores, a comunicação é literalmente o conjunto de ações comuns em um coletivo de agentes. Sob uma vertente enativa semiótica, decidimos então: 1. Replicar resultados de convergência léxica e ampliar os resultados obtidos por Loula et al. (2003) e Loula (...) (2004); 2. Para isso, foi concebido e implementado o SIMPS - Simulador de Processos Semióticos; e 3. Analisar o conceito de informação como ação significativa, isto é, como ações envolvidas em processos semióticos, cujos significados se encontram nos usos coletivos das palavras e expressões de jogos de linguagem. Apesar de entendermos que nem toda informação é adaptativa, buscamos gerar informações passíveis de trazer vantagens adaptativas para grupos de agentes. Nosso modelo de simulação aponta, dentre outros resultados, que informações falsas podem ser mais prejudiciais do que informação alguma. (shrink)
