Jose Marti contributed greatly to Cuba's struggle for independence from Spain with words as well as revolutionary action. Although he died before the formation of an independent republic, he has since been hailed as a heroic martyr inspiring Cuban republican traditions.

Paul Ricoeur realizó su primera incursión sobre la temática del mal en su primer periodo, conocido como filosofía de la voluntad, que comprende especialmente los libros "Lo voluntario y lo involuntario", "El hombre lábil" y "La simbólica del mal!. Este estudio pretende presentar las claves internas a partir de las cuales Ricoeur realiza su investigación, analizando los conceptos fundamentales sobre los que gira y su posterior desarrollo. También busca incidir en los presupuestos antropológicos de los que parte, para después (...) realizar análisis de las consecuencias éticas que tienen dichos presupuestos. En este sentido se ha prestado una especial atención a la vinculación existente de la investigación de Ricoeur con la teoría del conocimiento kantiana y con la filosofía hegeliana.. (shrink)

Este artigo tem o propósito de refletir o problema da morte a partir de uma abordagem da ética hermenêutica. Para isso, consultaremos os seguintes textos de Paul Ricoeur: O problema do fundamento da moral, Philosophie de la volonté - le volontaire et l’involontaire e Vivo até a Morte e O justo II, além dos comentadores desta matéria. O texto está organizado em três tópicos. O primeiro trata das expressões da liberdade como interação do agir humano, o segundo, refletiremos a (...) vida moral a partir das representações sobre a morte como interpelação ao sentido de agir e de existir e, por último abordaremos o objeto da reflexão a respeito da vida, da morte e da liberdade numa compreensão da bioética no pensamento do filósofo francês.

This paper considers how best an eliminativist might argue for the radical falsity of commonsense psychology. I will be arguing that Paul Churchland’s “official” arguments for eliminative materialism (in, e.g., Churchland 1981) are unsatisfactory, although much of the paper will be developing themes that are clearly present in Churchland’s writings. The eliminativist needs to argue that the representations that feed into action are fundamentally different from those invoked by propositional attitude psychology. The “springs of action” are representations of features (...) that are much more finely grained than those encoded within the vocabulary that we employ to specify the content of propositional attitudes. The eliminativist’s most promising strategy is to argue that, whatever we might think about why we behave the way we do, careful experimental work will show that we are in fact acting in virtue of representations of properties and microfeatures that fall completely outside the ambit of propositional attitude psychology. The paper considers a number of examples of how this eliminativist strategy might be developed, ranging from the implications of the two visual systems hypothesis to research in social psychology into the role that situational factors play in controlling action.

Just Ecological Integrity presents a collection of revised and expanded essays originating from the international conference "Connecting Environmental Ethics, Ecological Integrity, and Health in the New Millennium" held in San Jose, Costa Rica in June 2000. It is a cooperative venture of the Global Ecological Integrity Project and the Earth Charter Initiative.

In this paper, I endeavor to provide a critical examination of a recent pioneering work that engages Jean-Paul Sartre’s insights in analyzing social media interactions – Michael Lopato’s “Social media, love, and Sartre’s look of the other: Why online communication is not fulfilling?”. I shall show that in so far as Sartrean insights are concerned in Being and Nothingness, Lopato misconstrued what Sartre really meant with the Look of the Other and love, and is mistaken in appropriating such insights (...) in arguing that online interactions are not fulfilling. I shall proceed by first discussing Sartre’s third region of being which is being-for-others which will comprise of the Look of the Other and the two attitudes to retrieve one’s freedom. Second, I shall flesh out the arguments of Lopato. Lastly, I shall present my critique of Lopato’s arguments which constitutes my reply to his work. (shrink)

Este texto faz parte de pesquisa de doutoramento em Filosofia em andamento que procura investigar e analisar estes dois conceitos: Autonomia e Prática Pedagógica. A tentativa é mostrar que o conceito de autonomia poderá ser construído de acordo com a teoria da Liberdade em Jean Paul Sartre e o conceito de Prática Pedagógica a partir dos princípios e saberes apresentados por Paulo Freire. Assim, será possível analisar a Prática Pedagógica à luz do conceito de Autonomia.

Este texto apresenta o dossier temático “Temas clássicos em Ricoeur: hermenêutica, religião, reconhecimento”. A apresentação explica a origem dos artigos, procedentes do VII Congresso Ibero‑Americano sobre o Pensamento de Paul Ricoeur, “Ricoeur e os Clássicos”, expõe de forma sucinta a importância da reflexão sobre os clássicos no contexto da hermenêutica ricoeuriana, e introduz cada um dos artigos do dossier. A hermenêutica bíblica e a relação entre filosofia e religião, a própria noção de “clássico”, bem como a investigação da questão (...) do reconhecimento são exemplos de temas clássicos explorados aqui, no contexto do pensamento de Ricoeur.

In this article, based on the most important William of Ockham’s O. Min. writings, we analyze his ideias concerning the origins of the imperial and secular power. Founded in the Paul’s doctrine omnis potestas a Deo, but enlarged, per homines, and also on the ideas of his Franciscan brothers which lived before, which articulated the concepts of proprietas and domininum, in order to explain the human origins of the both, on the one hand, Ockham refuses not only the hierocratic (...) theory, but also Marsilius of Padua thought about this subject, and, on the other hand, he offers his contribution for this subject, according with which, nor the Empire neither the Estates are completely subordinated to the Church, nor the Church is subordinated for the secular power, because, referring its origins, both, Church and Estates are different origins, the first has a divine proceeding, the others, are immediately a human provenance and, because, in its specific spheres of action the spiritual power and the secular power do not depend one of the other and vice versa.Neste artigo, fundamentado nos principais escritos de Guilherme de Ockham, O. Min., analisamos sua concepção a respeito das origens dos poderes imperial e secular. Ancorado no versículo paulino omnis potestas a Deo, mas ampliado, sed per homines e, igualmente, nas ideias dos confrades que o antecederam, os quais relacionaram entre si os conceitos proprietas e dominium, com vista a explicar as origens humanas dos mesmos, de um lado, ele rebate tanto a teoria hierocrata quanto a de Marsílio de Pádua, relativas ao tema em exame e, de outro, oferece sua contribuição ao mesmo, mediante a qual, nem o Império nem os Estados estão completamente subordinados à Igreja, nem esta está submissa ao poder terreno, porque, quanto às origens de ambos, a Igreja tem uma procedência divina e os Estados e o Império têm imediatamente uma origem humana e, ainda, porque nas esferas respectivas de atuação, os poderes espiritual e secular independem um do outro.

Originating as a proponent of U.S. exceptionalism during the Cold War, American Studies has now reinvented itself, vigorously critiquing various kinds of critical hegemony and launching innovative interdisciplinary endeavors. _The Futures of American Studies_ considers the field today and provides important deliberations on what it might yet become. Essays by both prominent and emerging scholars provide theoretically engaging analyses of the postnational impulse of current scholarship, the field's historical relationship to social movements, the status of theory, the state of higher (...) education in the United States, and the impact of ethnic and gender studies on area studies. They also investigate the influence of poststructuralism, postcolonial studies, sexuality studies, and cultural studies on U.S. nationalist—and antinationalist—discourses. No single overriding paradigm dominates the anthology. Instead, the articles enter into a lively and challenging dialogue with one another. A major assessment of the state of the field, _The Futures of American Studies_ is necessary reading for American Studies scholars. _Contributors._ Lindon Barrett, Nancy Bentley, Gillian Brown, Russ Castronovo, Eric Cheyfitz, Michael Denning, Winfried Fluck, Carl Gutierrez-Jones, Dana Heller, Amy Kaplan, Paul Lauter, Günter H.

Por ocasião do centenário de nascimento de Paul Ricoeur, a Universidade de Coimbra juntou num mesmo volume um conjunto de estudos académicos em tributo a este pensador. Reuniram-se deste modo comunicações de professores, de novos investigadores e de estudantes de doutoramento em redor de temas que marcaram a receção da obra e do filósofo francês em Coimbra. Cada capítulo do presente livro demonstra a fecundidade de um pensamento que, enraizado na “tradição reflexiva”, assumindo a mensagem das “filosofias da existência”, (...) articulando Fenomenologia e Hermenêutica, adquire, hoje, crescente impacto e relevância. Esta é uma filosofia que promove o diálogo entre disciplinas, autores e culturas e supera divisões teóricas em ordem a enfrentar as exigências da praxis. O desafio da praxis fez assim emergir um pensamento exigente e, simultaneamente, capaz de dialogar com diversas áreas do saber como: a psicoterapia, a história, as neurociências, a bioética, as ciências sociais e os estudos literários. At the occasion of the Paul Ricoeur’s centenary this volume joined in tribute several scholars, young researchers, and Ph.D students around the main themes that marked the reception of the philosopher’s work in Portugal and, especially in the University of Coimbra. Each chapter demonstrates the vigour Ricoeur’s thought as it is rooted in the "reflexive tradition", as it assumed the "existentialist" horizon, as it articulated Phenomenology and Hermeneutics. This philosophical project as, today, an enormous range of influence. This is a project that promotes dialogue between disciplines, authors, and cultures, overcoming theoretical divisions in face the demands of praxis. From this rich and plural inspiration comes the ability to meet with other fields of thought, namely psychotherapy, history, neuroscience, bioethics, social sciences, and literary studies. (shrink)

A Text Worthy of Plotinus makes available for the first time information on the collaborative work that went into the completion of the first reliable edition of Plotinus’ Enneads: Plotini Opera, editio maior, three volumes (Brussels, Paris, and Leiden, 1951-1973), followed by the editio minor, three volumes (Oxford, 1964-1983). Pride of place is given to the correspondence of the editors, Paul Henry S.J. and Hans-Rudolf Schwyzer, with other prominent scholars of late antiquity, amongst whom are E.R. Dodds, B.S. Page, (...) A.H. Armstrong, and J. Igal S.J. Also included in the volume are related documents consisting in personal memoirs, course handouts and extensive biographical notices of the two editors as well as of those other scholars who contributed to fostering the revival of Plotinus in the latter half of the 20th century. Taken together, letters and documents let the reader into the problems – codicological, exegetical, and philosophical – that are involved in the interpretation of medieval manuscripts and their transcription for modern readers. Additional insights are provided into the nature of collaborative work involving scholars from different countries and traditions. A Text Worthy of Plotinus will prove a crucial archive for generations of scholars. Those interested in the philosophy of Plotinus will find it a fount of information on his style, manner of exposition, and handling of sources. The volume will also appeal to readers interested in broader trends in 20th century scholarship in the fields of Classics, History of Ideas, Theology, and Religion. (shrink)

The Developmental Systems approach to evolution is defended against the alternative extended replicator approach of Sterelny, Smith and Dickison (1996). A precise definition is provided of the spatial and temporal boundaries of the life-cycle that DST claims is the unit of evolution. Pacé Sterelny et al., the extended replicator theory is not a bulwark against excessive holism. Everything which DST claims is replicated in evolution can be shown to be an extended replicator on Sterelny et al.s definition. Reasons are given (...) for scepticism about the heuristic value claimed for the extended replicator concept. For every competitive, individualistic insight the replicator theorist has a cooperative, systematic blindspot. (shrink)

The etiological approach to ‘proper functions’ in biology can be strengthened by relating it to Robert Cummins' general treatment of function ascription. The proper functions of a biological trait are the functions it is assigned in a Cummins-style functional explanation of the fitness of ancestors. These functions figure in selective explanations of the trait. It is also argued that some recent etiological theories include inaccurate accounts of selective explanation in biology. Finally, a generalization of the notion of selective explanation allows (...) an analysis of the proper functions of human artifacts. (shrink)

In behavioral ecology some authors regard the innateness concept as irretrievably confused whilst others take it to refer to adaptations. In cognitive psychology, however, whether traits are 'innate' is regarded as a significant question and is often the subject of heated debate. Several philosophers have tried to define innateness with the intention of making sense of its use in cognitive psychology. In contrast, I argue that the concept is irretrievably confused. The vernacular innateness concept represents a key aspect of 'folkbiology', (...) namely, the explanatory strategy that psychologists and cognitive anthropologists have labeled 'folk essentialism'. Folk essentialism is inimical to Darwinism, and both Darwin and the founders of the modern synthesis struggled to overcome this way of thinking about living systems. Because the vernacular concept of innateness is part of folkbiology, attempts to define it more adequately are unlikely to succeed, making it preferable to introduce new, neutral terms for the various, related notions that are needed to understand cognitive development.

The relationship between individuals’ creativity and their ethical ideologies appears to be complex. Applying Forsyth’s (1980, 1992) personal moral philosophy model which consists of two independent ethical ideology dimensions, idealism and relativism, we hypothesized and found support for a positive relationship between creativity and relativism. It appears that creative people are less likely than non-creative people to follow universal rules in their moral decision making. However, contrary to our hypothesis and the general stereotype that creative people are less caring about (...) others, we found a positive relationship between creativity and idealism. These findings indicate that highly creative people are likely to be what Forsyth called “situationists,” individuals with both an ethic of caring and a pragmatic moral decision-making style. The finding that creative individuals tend to be situationists, and particularly that they tend to be high in idealism, appears to refute the line of reasoning that argues for a “creative personality” characterized in part by social insensitivity. Understanding the relationship between creativity and ethical ideologies has important implications for researchers, managers and teachers. (shrink)

In a recent article in this journal, Zachary Ardern criticizes our view that the most promising candidate for a naturalized criterion of disease is the "selected effects" account of biological function and dysfunction. Here we reply to Ardern’s criticisms and, more generally, clarify the relationship between adaptation and dysfunction in the evolution of health and disease.

In earlier work I have claimed that emotion and some emotions are not `natural kinds'. Here I clarify what I mean by `natural kind', suggest a new and more accurate term, and discuss the objection that emotion and emotions are not descriptive categories at all, but fundamentally normative categories.

It is unreasonable to assume that our pre-scientific emotion vocabulary embodies all and only those distinctions required for a scientific psychology of emotion. The psychoevolutionary approach to emotion yields an alternative classification of certain emotion phenomena. The new categories are based on a set of evolved adaptive responses, or affect-programs, which are found in all cultures. The triggering of these responses involves a modular system of stimulus appraisal, whose evoluations may conflict with those of higher-level cognitive processes. Whilst the structure (...) of the adaptive responses is innate, the contents of the system which triggers them are largely learnt. The circuits subserving the adaptive responses are probably located in the limbic system. This theory of emotion is directly applicable only to a small sub-domain of the traditional realm of emotion. It can be used, however, to explain the grouping of various other phenomena under the heading of emotion, and to explain various characteristic failings of the pre-scientific conception of emotion.

The emerging discipline of evolutionary developmental biology has opened up many new lines of investigation into morphological evolution. Here I explore how two of the core theoretical concepts in ‘evo-devo’ – modularity and homology – apply to evolutionary psychology. I distinguish three sorts of module – developmental, functional and mental modules and argue that mental modules need only be ‘virtual’ functional modules. Evolutionary psychologists have argued that separate mental modules are solutions to separate evolutionary problems. I argue that the structure (...) of developmental modules in an organism helps determine what counts as a separate evolutionary problem for that organism. I suggest that homology as an organizing principle for research in evolutionary psychology, has been severely neglected in favor of analogy (adaptive function). I consider some arguments suggesting that determining homology is less epistemically demanding than determining adaptive function and argue that psychological categories defined by homology are, in fact, more suitable objects of psychological – and particularly neuropsychological – investigation than categories defined by analogy.

The work presented here investigates the process by which one group of individuals solves the problem of detecting deceptions created by other agents. A field experiment was conducted in which twenty‐four auditors (partners in international public accounting firms) were asked to review four cases describing real companies that, unknown to the auditors, had perpetrated financial frauds. While many of the auditors failed to detect the manipulations in the cases, a small number of auditors were consistently successful. Since the detection of (...) frauds occurs infrequently in the work of a given auditor, we explain success by the application of powerful heuristics gained from experience with deceptions in everyday life. These heuristics implement a variation of Dennett's intentional stance strategy, which is based on interpreting detected inconsistencies in the light of the Deceiver's (i.e., management's) goals and possible actions. We explain failure to detect deception by means of perturbations (bugs) in the domain knowledge of accounting needed to apply these heuristics to the specific context of financial statement fraud. We test our theory by showing that a computational model of fraud detection that employs the proposed heuristics successfully detects frauds in the cases given to the auditors. We then modify the model by introducing perturbations based on the errors made by each of the auditors in the four cases. The resulting models account for 84 of the 96 observations (i.e., 24 auditors × four cases) in our data. (shrink)

Kenneth C. Schaffner's paper is an important contribution to the literature on behavioral genetics and on genetics in general. Schaffner has a long record of injecting real molecular biology into philosophical discussions of genetics. His treatments of the reduction of Mendelian to molecular genetics first drew philosophical attention to the problems of detail that have fuelled both anti-reductionism and more sophisticated models of theory reduction. An injection of molecular detail into discussions of genetics is particularly necessary at the present time, (...) when so many philosophers seem happy to discuss the philosophical and ethical implications of molecular biology using gene concepts derived from evolutionary biology ). Schaffner has long advocated the view that the philosophy of biology should be more than the philosophy of evolution. This paper shows how radically a picture of gene action derived from molecular biology undercuts the popular picture associated with a more evolutionary view of genes as units of heredity or as ‘difference-makers’ mediated by the ‘black box’ of development.

There remains a division between the work of philosophers who draw on the sciences of the mind to understand emotion and those who see the philosophy of emotion as more self-sufficient. This article examines this methodological division before reviewing some of the debates that have figured in the philosophical literature of the last decade: whether emotion is a single kind of thing, whether there are discrete categories of emotion, and whether emotion is a form of perception. These questions have been (...) addressed by both sides of the methodological divide and the integration of these two approaches would have clear benefits. (shrink)

This article examines and rejects the claim that 'innateness is canalization'. Waddington's concept of canalization is distinguished from the narrower concept of environmental canalization with which it is often confused. Evidence is presented that the concept of environmental canalization is not an accurate analysis of the existing concept of innateness. The strategy of 'biologicizing the mind' by treating psychological or behavioral traits as if they were environmentally canalized physiological traits is criticized using data from developmental psychobiology. It is concluded that (...) identifying innateness with environmental canalization can only result in adding unhelpful associations from 'folkbiology' to the relatively precise idea of canalization.

We outline three very different concepts of the gene—instrumental, nominal, and postgenomic. The instrumental gene has a critical role in the construction and interpretation of experiments in which the relationship between genotype and phenotype is explored via hybridization between organisms or directly between nucleic acid molecules. It also plays an important theoretical role in the foundations of disciplines such as quantitative genetics and population genetics. The nominal gene is a critical practical tool, allowing stable communication between bioscientists in a wide (...) range of fields grounded in well-defined sequences of nucleotides, but this concept does not embody major theoretical insights into genome structure or function. The post-genomic gene embodies the continuing project of understanding how genome structure supports genome function, but with a deflationary picture of the gene as a structural unit. This final concept of the gene poses a significant challenge to conventional assumptions about the relationship between genome structure and function, and between genotype and phenotype. (shrink)

A number of philosophers and ‘evolutionary psychologists’ have argued that attacks on adaptationism in contemporary biology are misguided. These thinkers identify anti-adaptationism with advocacy of non-adaptive modes of explanation. They overlook the influence of anti-adaptationism in the development of more rigorous forms of adaptive explanation. Many biologists who reject adaptationism do not reject Darwinism. Instead, they have pioneered the contemporary historical turn in the study of adaptation. One real issue which remains unresolved amongst these methodological advances is the nature of (...) ‘phylogenetic inertia’. To what extent is an adaptive explanation needed for the persistence of a trait as well as its origin? (shrink)

In this paper, the authors show that there is a reading of St. Anselm's ontological argument in Proslogium II that is logically valid (the premises entail the conclusion). This reading takes Anselm's use of the definite description "that than which nothing greater can be conceived" seriously. Consider a first-order language and logic in which definite descriptions are genuine terms, and in which the quantified sentence "there is an x such that..." does not imply "x exists". Then, using an ordinary logic (...) of descriptions and a connected greater-than relation, God's existence logically follows from the claims: (a) there is a conceivable thing than which nothing greater is conceivable, and (b) if <em>x</em> doesn't exist, something greater than x can be conceived. To deny the conclusion, one must deny one of the premises. However, the argument involves no modal inferences and, interestingly, Descartes' ontological argument can be derived from it. (shrink)

I defend the view that many biological categories are defined by homology against a series of arguments designed to show that all biological categories are defined, at least in part, by selected function. I show that categories of homology are `abnormality inclusive'—something often alleged to be unique to selected function categories. I show that classifications by selected function are logically dependent on classifications by homology, but not vice-versa. Finally, I reject the view that biologists must use considerations of selected function (...) to abstract away from variation and pathology to form a canonical description of a class of biological systems.

Experimental philosophy of science gathers empirical data on how key scientific concepts are understood by particular scientific communities. In this paper we briefly describe two recent studies in experimental philosophy of biology, one investigating the concept of the gene, the other the concept of innateness. The use of experimental methods reveals facts about these concepts that would not be accessible using the traditional method of intuitions about possible cases. It also contributes to the study of conceptual change in science, which (...) we understand as the result of a form of conceptual ecology, in which concepts become adapted to specific epistemic niches.

Because physical theories typically predict numerical values, an improvement in experimental precision reduces the tolerance range and hence increases corroborability. In most psychological research, improved power of a statistical design leads to a prior probability approaching 1/2 of finding a significant difference in the theoretically predicted direction. Hence the corroboration yielded by "success" is very weak, and becomes weaker with increased precision. "Statistical significance" plays a logical role in psychology precisely the reverse of its role in physics. This problem is (...) worsened by certain unhealthy tendencies prevalent among psychologists, such as a premium placed on experimental "cuteness" and a free reliance upon ad hoc explanations to avoid refutation.

Some ‘naturalist’ accounts of disease employ a biostatistical account of dysfunction, whilst others use a ‘selected effect’ account. Several recent authors have argued that the biostatistical account offers the best hope for a naturalist account of disease. We show that the selected effect account survives the criticisms levelled by these authors relatively unscathed, and has significant advantages over the BST. Moreover, unlike the BST, it has a strong theoretical rationale and can provide substantive reasons to decide difficult cases. This is (...) illustrated by showing how life-history theory clarifies the status of so-called diseases of old age.

It has been suggested that moods are higher order-dispositions. This proposal is considered, and various shortcomings uncovered. The notion of a higher-order disposition is replaced by the more general notion of a higher-order functional state. An account is given in which moods are higher-order functional states, and the overall system of moods is a higher-order functional description of the mind. This proposal is defended in two ways. First, it is shown to capture some central features of our pre-scientific conception of (...) moods. Secondly, it is argued that the account is more likely to be psychologically realistic (in a sense to be defined) than accounts which are behaviourally equivalent, but which do not employ a hierarchy of functional descriptions. It is suggested that the hierarchical structure of the model mirrors a feature of the physical states that realise moods and emotions. (shrink)

Several authors have argued that causes differ in the degree to which they are ‘specific’ to their effects. Woodward has used this idea to enrich his influential interventionist theory of causal explanation. Here we propose a way to measure causal specificity using tools from information theory. We show that the specificity of a causal variable is not well-defined without a probability distribution over the states of that variable. We demonstrate the tractability and interest of our proposed measure by measuring the (...) specificity of coding DNA and other factors in a simple model of the production of mRNA. (shrink)

The historian Raphael Falk has described the gene as a ‘concept in tension’ (Falk 2000) – an idea pulled this way and that by the differing demands of different kinds of biological work. Several authors have suggested that in the light of contemporary molecular biology ‘gene’ is no more than a handy term which acquires a specific meaning only in a specific scientific context in which it occurs. Hence the best way to answer the question ‘what is a gene’, and (...) the only way to provide a truly philosophical answer to that question is to outline the diversity of conceptions of the gene and the reasons for this diversity. In this essay we draw on the extensive literature in the history of biology to explain how the concept has changed over time in response to the changing demands of the biosciences . Finally, we outline some of the conceptions of the gene current today. The seeds of change are implicit in many of those current conceptions and the future of the gene concept looks set to be at as turbulent as the past. (shrink)
