In this paper, Tyson E. Lewis challenges the dominant theoretical and practical educational responses to globalization. On the level of public policy, Lewis demonstrates the limitations of both neoliberal privatization and liberal calls for rehabilitating public schooling. On the level of pedagogy, Lewis breaks with the dominant liberal democratic tradition which focuses on the cultivation of democratic dispositions for cosmopolitan citizenship. Shifting focus, Lewis posits a new location for education out of bounds of the common sense (...) of public versus private, nationalism versus cosmopolitanism, inclusion versus exclusion, human versus civil rights. This is the space of the commonwealth whose actors cannot be identified as ‘citizens’ but are rather the anonymous multitude. In conclusion, Lewis finds a model for organizing this commonwealth in the work of Ivan Illich, whose learning networks speak to the urgent political and pedagogical need for exodus from the conceptual vocabulary that defines much of the contemporary field of educational theory.

In this essay Tyson Lewis reevaluates Jean-Jacques Rousseau's assessment of the pedagogical value of fables in Emile's education using Giorgio Agamben's theory of poetic production and Thomas Keenan's theory of the inherent ambiguity of the fable. From this perspective, the “unreadable” nature of the fable that Rousseau exposed is not simply the result of a child's innocence or developmental immaturity, but is rather a structural quality of the fable as such. Moving from a discussion of Rousseau's description of the (...) fable and its relation to early childhood development, Lewis then telescopes outward into an analysis of Emile as a reenactment of the paradoxes of the fable. While Rousseau critiqued the pedagogical value of the fable, his own pedagogical project is informed by many of the qualities that he attributed to the fable. This return of the fable is enacted through Rousseau's writing on three interconnected levels: the question of the maxim, the paradox of truth, and the paradox of freedom. Lewis argues that if we take seriously the textually fabulous dimension of Emile, then the reader is left exposed to the very same anxieties as a child who is confronted with the ambiguity of the fable. In a concluding gesture, Lewis speculates about what Emile's fabulous dimension means for the practice of educational philosophy itself. (shrink)

This study compares the relationship between the moral reasoning modes and leadership orientation of males versus females, and managers versus engineers/scientists. A questionnaire developed by Worthley (1987) was used to measure the degree of each participant's respective independence and justice, and relationships and caring moral reasoning modes. Leadership orientation values and attitudes were measured using the Fiedler and Chemers (1984) Least Preferred Coworker Scale.The results suggest that, although males differ from female in their dominant moral reasoning modes, managers are not (...) distinguishable from the engineers/scientists they manage in terms of their moral reasoning mode or Least Preferred Coworker score.

In this article I argue that despite the claims of some, all whites in racialized societies "have race." But because of the current context of race in our society, I argue that scholars of "whiteness" face several difficult theoretical and methodological challenges. First is the problem of how to avoid essentializing race when talking about whites as a social collective. That is, scholars must contend with the challenge of how to write about what is shared by those racialized as white (...) without implying that their experiences of racialization all will be the same. Second, within the current context of color-blind racial discourse, researchers must confront the reality that some whites claim not to experience their whiteness at all. Third, studies of whiteness must not be conducted in a vacuum: racial discourse or "culture" cannot be separated from material realities. Only by attending to and by recognizing these challenges will empirical research on whiteness be able to push the boundaries of our understandings about the role of whites as racial actors and thereby also contribute to our understanding of how race works more generally.

There is an increased controversy surrounding Westerners' use of ayahuasca. One issue of importance is psychological resiliency of users and lack of screening by ayahuasca tourism groups in the Amazon. Given the powerful effects of ayahuasca coupled with lack of cultural support, Western users are at increased risk for psychological distress. Many Westerners who experience psychological distress following ayahuasca ceremonies report concurrently profound spiritual experiences. Because of this, it may be helpful to consider these episodes "spiritual emergencies," or crises resulting (...) from intense and transformative spiritual experiences. Although the author warns readers to avoid romantic comparisons of Western ayahuasca users to shamans, ethnographic data on indigenous shamanic initiates along with theory on liminality may be of some use to understand difficult experiences that accompany ayahuasca use. Given that psychotherapy is culturally sanctioned, therapists trained in treating spiritual crises can help Western ayahuasca users make meaning of their distress. Three case studies are offered as examples of individuals working through various sorts of crises following ayahuasca ceremonies. (shrink)

In this article, the author rethinks critiques of the learning society using Giorgio Agamben’s theory of potentiality. Summarizing several major contributions to our understanding of the limitations of the discourse of learning, the author proposes that critics thus far have failed to fully pinpoint the exact danger of learning. Importantly, learning is not only a rejection of the democratic or political dimension of education but it is first and foremost predicated on a false ontology of potentiality. What is put at (...) risk in learning is a sacrifice of our (im)potential, our capacity to be or not to be this or that within the order of things. Through a reconstruction of Agamben’s theory of studying, the author argues for a different conceptualization of freedom in education, of teaching, and of the time of education. (shrink)

In this paper, the author maps three radically different visions of Marxism in educational philosophy. Each ‘register’ contains insights but also contradictions that cannot easily be resolved through internal modifications of the theory or through theoretical synthesis with other registers. The radical function of Marxist pedagogy is to create a constellation of Marxisms through which the outline of history can emerge. As such, the author ends with a new emphasis in Marxist education on the ‘exacting imagination’ of the teacher which (...) creates a constellational image of concepts and theories all of which hang in a precarious and historically specific configuration.

Working through the lens of Donna Haraway's cyborg theory and directed at the example of Prozac, I address the dramatic rise of new technoscience in medicine and psychiatry. Haraway's cyborg theory insists on a conceptualization and a politics of technoscience that does not rely on universal Truths or universal Goods and does not attempt to return to the pure or the natural. Instead, Haraway helps us mix politics, ethics, and aesthetics with science and scientific recommendations, and she helps us understand (...) that (without recourse to universal truth or universal good) questions of legitimacy in science come down to local questions of effect and inclusion. What, in the case of my example, are the effects of Prozac? And for whom? Who is included and empowered to create legitimate psychiatric knowledge? Who is excluded and why? And, what political strategies will increase the democratic health of psychiatric science and practice? (shrink)

Plagiarism strikes at the heart of academe, eroding the fundamental value of academic research. Recent evidence suggests that acts of plagiarism and awareness of these acts are on the rise in academia. To address this issue, a vein of research has emerged in recent years exploring plagiarism as an area of academic inquiry. In this new academic subject, case studies and analysis have been one of the most influential methodologies employed. Case studies provide a venue where acts of plagiarism can (...) be discussed and analyzed in a constructive manner, and that is the primary purpose of this article. Unlike previous studies, however, we focus on the role of the publisher, a key player in dealing with acts of plagiarism, but one who has received little attention in the academic literature. Specifically, we examine how an academic publisher addressed allegations of plagiarism and how the publisher’s decision-making affected the outcome. We analyze the case by applying the guidelines from different frameworks and ethical theory and develop recommendations from the lessons evidenced, the second main objective of our article. This analysis advances the dialog on academic plagiarism by exploring the role of the publisher from a deontological perspective of ethical absolutism. (shrink)

This article introduces cultural studies of medicine to medical humanities readers. Rather than offer extended definitions of cultural studies of medicine or provide a detailed history of the domain, I have organized this introduction around a close reading and review of three recently published texts in the field. These three texts, dealing respectively with cyborg technology, AIDS, and the medical management of sexual identity problems, represent excellent examples of the opportunities and possibilities of applying cultural studies approaches to medical topics. (...) After working through these texts (and the semiotic theories which animate them), I devote my conclusion to a broader consideration of the role of cultural studies of medicine for both medical practice and medical humanities scholarship.

Often when I am teaching philosophy of education, my students begin the process of inquiry by prefacing their questions with something along the lines of "I'm just curious, but . . . ." Why do we feel compelled as teachers and as students to express our curiosity as just curiosity? Perhaps there is a slight embarrassment in proclaiming our curiosity, which, in its strongest formulation, appears to be too assertive, too aggressive, or too inappropriate to speak in public in front (...) of others. In this sense, curiosity is itself problematic, something to be slightly ashamed of. Or are we afraid that our teachers and our classmates will think that our questions are motivated by something more than mere curiosity? The .. (shrink)

This volume considers the many areas where medicine intersects with the law. Advances in medical research, reproductive science and genetics have given rise to unprecedented ethical and legal quandaries. These are reflected in chapters on cloning, organ donation, choosing genetic characteristics, and the use of Viagra.

In this essay, I argue that the work of Giorgio Agamben provides us with a theory of studious play which cuts across many of the categories that polarize educational thought. Rather than either ritualized testing or constructivist playfulness, Agamben provides a model of what he refers to as studious play—a practice which suspends the logic of both ritual and play. In order to explore this notion of studious play, I first articulate Agamben’s fleeting remarks on the topic with an important (...) problematic found in his early, literary work: transmission. If ritual transmits cultural traditions to ensure continuity with the past, and play as constructivist invention makes such transmission impossible, then studious play transmits transmissibility itself as a pure potentiality. Studious play accomplishes this peculiar educational task by suspending without destroying traditional things: laws, signs, and so on. I end the essay with a consideration of the ontological status of suspended things, arguing that they are transformed into toys via the action of study. Finally, I give a literary example of studious play found in Robert Walser’s novel Jakob von Gunten in which the school itself is imagined to be a kind of toy. (shrink)

This article describes how a unique high school programme, not formally designed to teach moral principles or character lessons, contributed substantially to the character education of its students. Graduates over 20 years old were interviewed ( n =106) and completed a questionnaire ( n =204). Findings suggest the programme teachers helped students develop character attributes by providing a desirable character education environment. A majority of students reported that the programme was personalised, practical and, in many cases, life changing. A majority (...) of the students also indicated that the programme helped them develop an appreciation and respect for others and the environment, while helping them prepare for higher education. We present this programme as a model for character education at the high school level. Details are presented so that the programme can be replicated in other settings. We conclude that the success of this programme can be understood in terms of teachers' willingness to encourage students to take responsibility for their lives, and their learning through modeling of high character values, use of an integrated and experiential curriculum, and employment of a dialogical perspective on active education.

Biological scientists are increasingly encountering work-related ethical problems. For most, their training leaves them quite unprepared. Rather than merely providing additional bolt-on courses in ethics, a way of introducing critical thinking skills seamlessly into the curriculum is proposed. A method is described whereby students become engaged in self-generated discussion about the scientifically recognized, but philosophically complex, terms ‘disease’ and ‘health.’ Addressing these words, students are confrontedwith the need to develop critical thinking skills without realizing that they are entering into overt (...) philosophical argument—the like of which many often prejudge to be abstract and worthless.

I examine recent arguments based on functionalism that claim to show that Bohm's theory fails to solve the measurement problem, or if it does so, it is only because it reduces to a form of the many-worlds theory. While these arguments reveal some interesting features of Bohm's theory, I contend that they do not undermine the distinctive Bohmian solution to the measurement problem. ‡I would like to thank Harvey Brown, Martin Thomson-Jones, and David Wallace for helpful discussions. †To contact the (...) author, please write to: Department of Philosophy, University of Miami, P.O.

Sustainable investment (SI), which integrates social, environmental and ethical issues, has grown from a niche market of individual ethical investors to embrace institutional investors (e.g. pension funds) resulting in £764 billion in assets under management in the UK alone [Eurosif, 2008 : ‘European SRI Study 2008’ (Eurosif, Paris)]. Explaining this growth is complex, involving shifts in personal and collective values, reactions to corporate scandals, scientific and media pronouncements about climate change, Government initiatives, responses from financial markets and the influence of (...) SI innovators in The City of London. The article examines the influence of human agency through interviews with 14 SI champions who have variously been responsible for launching SI funds and changing investment processes and organisational structures in order to enhance SI. Interviewees were asked about their motivations and persuasive strategies, the obstacles they faced and how they overcame them as well as broader implications of SI for financial markets. The following key categories inform the results and the discussion: Values; Conservatism, Antipathy and Incredulity; Optimism and Sympathy from Insiders; The Social and Political Context; The Business Case; Organisational Constraints; Inappropriate forms of Remuneration; Short-termism; The Nature of Capitalism. Three discourses were also identified. The first is the necessity to make a business case for SI; the second is the benefits that SI can bring to the quest of overcoming short-termism; the third is a belief that for SI to have a significant influence, greater government intervention is required.

The main problem with the many‐worlds theory is that it is not clear how the notion of probability should be understood in a theory in which every possible outcome of a measurement actually occurs. In this paper, I argue for the following theses concerning the many‐worlds theory: (1) If probability can be applied at all to measurement outcomes, it must function as a measure of an agent’s self‐location uncertainty. (2) Such probabilities typically violate (...) reflection. (3) Many‐worlds branching does not have sufficient structure to admit self‐location probabilities. (4) Decision‐theoretic arguments do not solve this problem. †To contact the author, please write to: Department of Philosophy, University of Miami, P.O.

Many philosophers have maintained that secondary qualities are private mental entities. In this paper I use the discussions of H. A. Prichard, Berkeley and G. E. Moore on the status of secondary qualities to bring out the assumptions that underlie this view. One of these is that secondary qualities are particular. I show that Prichard holds these assumptions and then I attempt to diagnose why he holds them. In the course of this diagnosis I explore several senses of 'dependent' which (...) play a role in this view. Finally, I show that a causal dependence of secondary qualities upon the perceiver will not lead to the conclusion that secondary qualities are private unless the philosophical thesis that they are particular is already assumed.

The longstanding interest in business ethics has been given renewed emphasis by high profile scandals in the world of business and finance. At the same time, many economists--dissatisfied with the discipline's emphasis on self-interest and individualism and by the asocial nature of much economic theory--have sought to englarge the scope of economics by looking at ethical questions. In Ethics and Economic Affairs a group of interdisciplinary scholars provide contributions on international interest in this aspect of socio-economics and economic-psychology. The book (...) is divided into four parts. The first looks at Business Ethics and Management. Part Two enlivens the debate with empirical data. The third part examines the implications for economic theory and asks if the integration of ethics in the economy is possible or if they are fundamentally different systems. Part Four introduces perspectives from other disciplines, sets economics within its wider context and looks to the future. The editors have brought together a group of contributors from nine different countries and a broad range of disciplines, including: Norman E. Bowie, Monroe Burk, Amitai Etzioni, Richard H. Guerette, Ralph E. Miner, Lynne M. Rosansky, N. Craig Smith, Roberts Stallaerts, Philip Stone and John Tomer. (shrink)

David Pears's contention that the Tractatus is to be understood as advancing a form of metaphysical realism is defended against McGuinness's view that Tractatus 1-2.063 is to be treated just as introducing a metaphysical myth that may be employed to bring into prominence salient features of propositions. Starting with a discussion of the involved difficulties, e.g., determining (1) whether Wittgenstein does in fact provide an argument for the existence of simple objects (2) what this object is and (3) what role (...) the existence of simple objects plays within the Picture Theory of the Proposition, Wittgenstein's argument for the existence of simple objects is reconstructed, augmenting Pears's existing account by providing further details of why Wittgenstein held that determinacy of sense requiresthe existence of simple objects.

Quasi al termine della seconda guerra mondiale, alcuni ufficiali tedeschi diedero l’ordine di abbattere le storiche torri di San Gimignano; tutto pareva ormai deciso, quando un gruppo di civili riuscì con successo a ritardare l’esecuzione fino all’arrivo delle truppe alleate. Grazie a quei civili, le torri di San Gimignano sono ancora ben visibili a tutti, meta ogni anno di numerosi turisti; ma che cosa dire della possibilità che oggi esistessero soltanto le loro macerie? Esse rientrano in quella classe di cose (...) che chiamerò oggetti possibili, ovvero sono oggetti che avrebbero potuto esistere, ma per un qualche motivo non sono esistiti. Proprio di essi parlerò nelle prossime pagine, cercando di capire quale sia il loro statuto ontologico e in quale modo possiamo parlarne usando le espressioni del nostro linguaggio.1 Come vedremo, ci sono varie teorie che spiegano cos’è un oggetto possibile, tra loro anche molto diverse. Compito di ciascuna è quello di motivare e, se necessario, rendere plausibile una scelta filosofica. Quindi, ogni teoria degli oggetti possibili, attribuirà loro un preciso statuto ontologico e provvederà una semantica delle espressioni del linguaggio naturale sulla possibilità. Nelle poche pagine che seguono però, non scenderò nei dettagli di tutte le teorie della possibilità; piuttosto, ne considererò una particolarmente controversa e singolare: quella sostenuta da David K. Lewis. (shrink)

It is sometimes claimed (e.g., by Sider (2001a,b); Holton (2003); Stalnaker (2004); Williams (2007); Weatherson (2003, 2010)) that a theory of predicate meaning that assigns a central role to naturalness is either (a) Lewisian, (b) true, or (c) both. The theory in question is rarely developed in particularly great detail, but the rough intuitive idea is that the meaning of a predicate is the most natural property that is more-or-less consistent with the usage of the predicate. The point of this (...) note is to investigate whether a version of this idea could be true, and whether it could be properly attributed to Lewis. I’m going to mostly focus on the second question, but I think in such a way that light is shed on the first question. To anticipate the answer a little, I’m going to say that whether the use plus naturalness theory is plausibly attributed to Lewis (and is plausibly true) depends on what we want a theory of (predicate) meaning to do. Here are two very distinct tasks we could be engaged in. First, we could be investigating the metaphysics of meaning, and so be interested in how it is that a pattern of animal noises can come to have any kind of content at all. Second, we could be investigating the meaning of some particular term, where substantive claims about the meanings of other terms are presupposed in our inquiry. Call the first project metasemantics, and the second project applied semantics. I’m going to conclude that use plus naturalness is a plausible way to approach applied semantics. But it isn’t a great way to approach metasemantics. The problem is that once we crunch through the details, it’s impossible to disentangle a notion of “use” such that naturalness can be added to it to get a theory of meaning. Before we can get very far on any of these inquiries, we need to say a bit about what we mean by ‘naturalness’. Naturalness plays a lot of distinctive roles for Lewis. Some of these broadly metaphysical roles. These roles are the primary focus of (Lewis, 1983a).. (shrink)

Like many discussions on the pros and cons of epistemic foundationalism, the debate between C.I. Lewis and H. Reichenbach dealt with three concerns: the existence of basic beliefs, their nature, and the way in which beliefs are related. In this paper we concentrate on the third matter, especially on Lewis’s assertion that a probability relation must depend on something that is certain, and Reichenbach’s claim that certainty is never needed. We note that Lewis’s assertion is prima (...) facie ambiguous, but argue that this ambiguity is only apparent if probability theory is viewed within a modal logic. Although there are empirical situations where Reichenbach is right, and others where Lewis’s reasoning seems to be more appropriate, it will become clear that Reichenbach’s stance is the generic one. This follows simply from the fact that, if P(E|G) > 0 and P(E|not-G) > 0, then P(E) > 0. We conclude that this constitutes a threat to epistemic foundationalism. (shrink)

This article opposes a view widely accepted in studies concerning the history of modal logic, according to which (i) the approach of C. I. Lewis towards constructing modern modal logic was purely syntactical (i.e. limited to the construction of axiomatic systems S1-S5 of propositional modal logic), and (ii) the notion of a possible world was incorporated into modern logic and philosophy mainly by authors such as Rudolf Carnap and Saul Kripke. The article presents Lewis' definition of a possible (...) world, and his formulation of the truth-conditions of statements containing strict implication as their main connective in terms of possible worlds. The main question of the article is whether it is possible to consider Lewis' work in this area as an early stage of the development of possible world semantics, and if so, in what sense? The article concludes by answering affirmatively, due to soundness and completeness proofs with respect to S5 using Lewis' semantics. (shrink)

I commemorate David Lewis by discussing an aspect of modality within analytical mechanics, which is closely related to his work on counterfactuals. This concerns the way Hamilton‐Jacobi theory uses ensembles, i.e. sets of possible initial conditions. (A companion paper discusses other aspects of modality in analytical mechanics that are equally related to Lewis's work.).

In his metaphysical summa of 1986, The Plurality of Worlds, David Lewis famously defends a doctrine he calls ‘modal realism’, the idea that to account for the fact that some things are possible and some things are necessary we must postulate an infinity possible worlds, concrete entities like our own universe, but cut off from us in space and time. Possible worlds are required to account for the facts of modality without assuming that modality is primitive – that there (...) are irreducibly modal facts. We argue that on one reading, Lewis’s theory licenses us to assume maverick possible worlds which spread through logical space gobbling up all the rest. Because they exclude alternatives, these worlds result in contradictions, since different spread worlds are incompatible with one another. Plainly Lewis’s theory must be amended to exclude these excluders. But, we maintain, this cannot be done without bringing in modal primitives. And once we admit modal primitives, bang goes the rationale for Lewis’s modal realism. (shrink)

In a survey of his views in the philosophy of mind, David Lewis criticizes much recent work in the ?eld by attacking an imaginary opponent,.

August 16, 1997 David Lewis2 has long defended an account of scientific law acceptable even to an empiricist with significant metaphysical scruples. On this account, the laws are defined to be the consequences of the best system for axiomitizing all occurrent fact. Here "best system" means the set of sentences which yields the best combination of strength of descriptive content 3 with simplicity of exposition. And occurrent facts, the facts to be systematized, are roughly the particular facts about a localized (...) space-time region that are non-modal, non-dispositional, and non-causal. Scientists providing or attempting to provide laws are plausibly seen as giving general principles that unify a body of data. Thus they organize or systematize the arrangement of occurrences. For this reason, Lewis's account has the important merits of providing contact with actual scientific practice while making sense of the standard philosophical conception that laws should be general but more than mere accidental generalizations. However, Lewis has long known about a potential problem with this account, a problem involving chance and credence.4 In a recent series of articles he, Michael Thau, and Ned Hall have developed a new formulation of the relationship between chance and credence which solves the problem. However, I will argue that these articles leave untouched and even exacerbate a closely related and more fundamental problem with the best system account, the problem of nomic necessity. Laws are supposed to be more than true; in some sense they must be true. Yet a principle's membership in the best systematization for one world seems to say nothing about its necessity, i.e., its truth at other worlds. I close by briefly describing how an alternative empiricist account may remove both problems. (shrink)

In his 1988 review of On the Plurality of Worlds (Lycan [1988]), William Lycan argued that what he called Lewis's 'mad-dog modal realism' (also 'rape-and-loot modal realism' and 'nuclear-holocaust modal realism' - I suspect that some reference to the supposed extremity of Lewis's position is intended) rested upon an unanalysed modal notion. Lycan accepted that actualists all seemed to be stuck with such unanalysed notions (adding that his own was the notion of compatibility as applied to pairs of (...) properties), but argued that Lewis's notion of worlds was also a modal primitive: 'World' for him has to mean 'possible world', since the very flesh-and-bloodiness [which relieves him of the sort of abstraction indulged in by actualists] prevents him from admitting impossibilia. (Lycan [1988], p.46) Lycan's main concerns in this review go back to his earlier paper 'The Trouble with Possible Worlds' (Lycan [1979]), and are taken up again in his PAS paper: The ruling out of impossible worlds is a serious liability [...] For semantics needs impossible worlds. Though standard modal logics may trade just in possible states of affairs, the semantics of conditionals must deal with inconsistent beliefs. (Lycan [1991], p.224) He goes on to claim that the actualist has no problem with impossible worlds. An impossible world is just - e.g. - a set of propositions (one of which happens to be inconsistent). (loc.cit.) Whatever the truth of this in principle, most actualists have either explicitly or implicitly excluded possible worlds from their theories.* It is true, nevertheless, that Lewis has a clear problem with the very idea of worlds at which logically incompatible propositions are true. Lycan attempts to exploit this as follows. (shrink)

C I Lewis showed up Down Under in 2005, in e-mails initiated by Allen Hazen of Melbourne. Their topic was the system Hazen called FL (a Funny Logic), axiomatized in passing in Lewis 1921. I show that FL is the system MEN of material equivalence with negation. But negation plays no special role in MEN. Symbolizing equivalence with → and defining ∼A inferentially as A→f, the theorems of MEN are just those of the underlying theory ME of pure (...) material equivalence. This accords with the treatment of negation in the Abelian l-group logic A of Meyer and Slaney (Abelian logic. Abstract, Journal of Symbolic Logic 46, 425–426, 1981), which also defines ∼A inferentially with no special conditions on f. The paper then concentrates on the pure implicational part AI of A, the simple logic of Abelian groups. The integers Z were known to be characteristic for AI, with every non-theorem B refutable mod some Zn for finite n. Noted here is that AI is pre-tabular, having the Scroggs property that every proper extension SI of AI, closed under substitution and detachment, has some finite Zn as its characteristic matrix. In particular FL is the extension for which n = 2 (Lewis, The structure of logic and its relation to other systems. The Journal of Philosophy 18, 505–516, 1921; Meyer and Slaney, Abelian logic.

As is known, a logic S is paraconsistent if the rule ECQ (E contradictione quodlibet) is not a rule of S. Not less well known is the fact that Lewis’ modal logics are not paraconsistent. Actually, Lewis vindicates the validity of ECQ in a famous proof currently known as the “Lewis’ proof” or “Lewis’ argument.” This proof essentially leans on the Disjunctive Syllogism as a rule of inference. The aim of this paper is to define a (...) series of paraconsistent logics included in S4 where the Disjunctive Syllogism is valid only as a rule of proof. (shrink)

Neste artigo, procuro extrair algumas conseqüências da lição de Lewis Carroll sobre a diferença entre premissas e regras de inferência no tocante aos raciocínios práticos. Meu questionamento dirige-se à clássica suposição formalista contida na famosa “Lei de Hume”, a saber, a regra formulada, dentre outros, por Richard Hare, de que é logicamente impossível derivar-se uma conclusão moral prática apenas de premissas fatuais. Na primeira parte deste artigo, proponho que o leitor imagine-se numa situação hipotética, na qual adota uma postura (...) evasiva mesmo diante de razões prima facie suficientes para tomar uma certa decisão. A situação apresentada é uma versão do “análogo prático”, engenhosamente construído por G. F. Schueler, ao clássico paradoxo de Lewis Carroll, contido em sua conhecida e genial estória da disputa entre Aquiles e a Tartaruga, publicada originalmente na revista Mind, em 1895. Na segunda parte, relembro e brevemente analiso a fábula carrolliniana, comparando-a com a versão prática de Schueler, discutindo suas analogias e dessemelhanças. Na terceira parte, mostro como as duas estórias são capazes de nos ajudar a desvendar alguns malentendidos sobre o raciocínio prático e sobre suas imbricações com a ética, em especial, com a conhecida tese de que de fatos não derivamos normas. Pretendo mostrar como essa famosa tese é vítima do mesmo vício formalista denunciado por Lewis Carroll, a saber, que é fruto de entendimentos equívocos acerca dos papéis que podem ser desempenhados por uma norma em um raciocínio prático, isto é, que, primariamente, normas, na condição de regras práticas, não figuram propriamente como premissas, e sim como regras especiais ou materiais de inferência. Se minha tese for verdadeira, então a alegação de que não podemos derivar “normas” de “fatos” resulta, na verdade, de um mal-entendido. Na última parte do artigo, destaco algumas outras confusões acerca do significado do termo ‘dever’ tal como esse termo é empregado usualmente em conclusões de raciocínios práticos. Numa referência a Stanley Cavell, sustentarei que o termo ‘dever’ serve-nos, nessa condição, de modo de apresentação do conteúdo das premissas que temos ou das razões que oferecemos para agir de uma certa maneira. Sendo assim, o termo ‘dever’, que usamos para apresentar a conclusão de um raciocínio prático, não pode ser interpretado, de maneira simplista (tal como fazem os defensores de visões kantianas sobre a ética), como tendo o mesmo sentido que o termo ‘obrigação’, cujo significado é mais estrito.

Terms such as ‘exist’, ‘actual’, etc., (hereafter, “ontic terms”) are recognized as having ontologically neutral or non-commissive uses, besides their standard commissive uses. (Consider, e.g., the two interpretations of ‘There is an even prime.’) In this paper, I identify six different non-commissive uses for ontic terms, and along the way I attempt to define (by a kind of via negativa) the commissive use of an ontic term, specifically, the commissive use of ‘actual’. The problem, however, is that the resulting definiens (...) for the commissive ‘actual’ is itself equivocal between a commissive and a non-commissive reading, and thus I consider other proposals for defining the commissive use, including two proposals from David Lewis. However, each proposal is found to be equivocal in the same way--and eventually I argue that it is impossible to define an ontic term unequivocally. Even so, this is not meant to overshadow the fact that we can understand an ontic term as univocally commissive, in certain conversational contexts. I close by applying these observations to the Hirsch-Sider debate in metaontology. (shrink)

Throughout the 20th century, an enormous amount of intellectual fuel was spent debating the merits of a class of skeptical arguments which purport to show that knowledge of the external world is not possible. These arguments, whose origins can be traced back to Descartes, played an important role in the work of some of the leading philosophers of the 20th century, including Russell, Moore and Wittgenstein, and they continue to engage the interest of contemporary philosophers. (e.g., Cohen 1999, DeRose 1995, (...) Hill 1996, Klein 1981, Lewis 1996, McGinn 1993, Nozick 1981, Schiffer 1996, Unger 1975, Williams 1996) Typically, these arguments make use of one or more premises which the philosophers proposing them take to be intuitively obvious. Beyond an appeal to intuition, little or no defense is offered, and in many cases it is hard to see what else could be said in support of these premises. A number of authors have suggested that the intuitions undergirding these skeptical arguments are universal – shared by everyone (or almost everyone) who thinks reflectively about knowledge. In this paper we will offer some evidence indicating that they are far from universal. Rather, the evidence suggests that many of the intuitions epistemologists invoke vary with the cultural background, socioeconomic status and educational background of the person offering the intuition. And this, we will argue, is bad news for the skeptical arguments that rely on those intuitions. The evidence may also be bad news for skepticism itself – not because it shows that skepticism is false, but rather because, if we accept one prominent account of the link between epistemic intuitions and epistemic concepts, it indicates that skepticism may be much less interesting and much less worrisome than philosophers have taken it to be.

Existence in Black is the first collective statement on the subject of Africana Philosophy of Existence. Drawing upon resources in Africana philosophy and literature, the contributors explore some of the central themes of Existentialism as posed by the context of what Frantz Fanon has identified as "the lived-experience of the black." Among questions posed and explored in the volume are: What is to be done in a world of near universal sense of superiority to, if not universal hatred of, black (...) folk?; What is black suffering?; What is the meaning (if any) of black existence? The introduction argues that a response to these questions requires a journey through the resources of identity questions in critical race theory and the teleological dimensions of liberation theory. The contributors address these questions through an analysis of nearly every dimension of Africana phiosophy. In the first half of the book, they address Black Philosophies of Existence in terms of Traditional African Philosophy, the Harlem Renaissance, Du Boisian Double-Consciousness, and Fanonian and Sartrean Philosophies of Existence. In the second half of the book, contributors consider racial identity through examinations of such concepts as equality, death, mimesis, property, embodiment, technology, disappointment, and dread. Part II is an exploration of postmodern challenges to "black existence" through discussions of postmodern conservatism, Nietzsche's thoughts on blacks, Richard Wright and fragmented consciousness, and feminist critiques of race. And Part IV is an examination of problems of historical responsibility and constructing black liberation theories. Contributors are: Ernest Allen, Jr., Robert Birt, Bernard Boxill, George Carew, Bobby Dixon, G.M. James Gonzales, Lewis R. Gordon, Leonard Harris, Floyd Hayes, III, Paget Henry, Patricia Huntington, Joy Ann James, Clarence Shole Johnson, Bill E. Lawson, Howard McGary, Roy D. Morrison, William Preston, Jean-Paul Sartre, T. Denean Sharpley-Whiting, Gary Schwartz, Robert Westley, and Naomi Zack. (shrink)

In this undergraduate textbook Lewis R. Gordon offers the first comprehensive treatment of Africana philosophy, beginning with the emergence of an Africana (i.e. African diasporic) consciousness in the Afro-Arabic world of the Middle Ages. He argues that much of modern thought emerged out of early conflicts between Islam and Christianity that culminated in the expulsion of the Moors from the Iberian Peninsula, and from the subsequent expansion of racism, enslavement, and colonialism which in their turn stimulated reflections on reason, (...) liberation, and the meaning of being human. His book takes the student reader on a journey from Africa through Europe, North and South America, the Caribbean, and back to Africa, as he explores the challenges posed to our understanding of knowledge and freedom today, and the response to them which can be found within Africana philosophy.

In virtue of what do the utterances we make mean what they do? What facts about these signs, about us, and about our environment make it the case that they have the meanings they do? According to a tradition stemming from H.P. Grice through David Lewis and Stephen Schiffer it is in virtue of facts about conventions that we participate in as language users that our utterances mean what they do (see Gr'ice 1957, Lewis 1969, 1983, Schiffer (...) 1972, 1982). This view currently enjoys widespread acceptance among philosophers of mind and language. Though most are not particularly interested in the details of such programs, the dominant view seems to be that something of the sort proposed by Grice, Lewis and Schiffer is basically right. Thus, Jerry Fodor, refiecting what I take to be prevalent attitudes in the field, writes. (shrink)

A major contribution to Descartes studies, this book provides a panorama of cutting-edge scholarship ranging widely over Descartes's own primary concerns: metaphysics, physics, and its applications. It is at once a tool for scholars and--steering clear of technical Cartesian science--an accessible resource that will delight nonspecialists. The contributors include Edwin Curley, Willis Doney, Alan Gabbey, Daniel Garber, Marjorie Grene, Gary Hatfield, Marleen Rozemond, John Schuster, Dennis Sepper, Stephen Voss, Stephen Wagner, Margaret Welson, Jean Marie Beyssade, Michelle Beyssade, Michel (...) Henry, Evert van Leeuwen, Jean-Luc Marion, Genevieve Rodis-Lewis, and Jean-Pierre Seris. Combining new textual sensitivity with attentiveness to history, they represent the best established scholars and most exciting new voices, including both English speaking and newly-translated writers. Part I examines the foundations of Descartes's philosophy: Cartesian certainty; the phenomenology of the cogito and its modulations in the passions; and the defensibility and comprehensibility of the Cartesian God. The second part examines Descartes's groundbreaking metaphysics: mind's distinctness from and interaction with body; imagination; perception; and language. Part III examines Cartesian science: the revolutionary rhetoric of the Rules and the Discourse; the metaphysical foundations of physics; the interplay of rationalism and empiricism; the mechanics and human biology that flow from Descartes's physics.
