Building on a model first proposed by Gary Johnson, it is hypothesized that religious institutions demanding celibacy and other forms of altruism from members take advantage of human predispositions to favor genetic relatives in order to maintain and reinforce these desired behaviors in non-kin settings. This is accomplished through the institutionalization of practices to manipulate cues through which such relatives are regularly identified. These cues are association, phenotypic similarity, and the use of kin terms. In addition, the age of recruits (...) and their contact with actual kin are factors that relate to kinship recognition and that are similarly manipulated by institutions in order to reinforce altruistic behavior directed toward non-kin. Support for this set of predictions is presented from historical and ethnographic sources on monastic life in Buddhism, Christianity, and Hinduism, as well as Islamic dervish groups, the Essenes, Shakers, and others. Potential implications of the model for understanding the development of religious institutions are preliminarily explored by reviewing Joachim Wach's model of religious developmental stages as well as some of the literature on the relationship between individualism and communalism in incipient religious organizations, in light of the kin-cue manipulation model.

In recent years, much has been learned about the strategic and organizational contexts of suicide attacks. However, motivations of the agents who commit them remain difficult to explain. In part this is because standard models of social learning as well as Durkheimian notions of sacrificial behavior are inadequate in the face of the actions of human bombers. In addition, the importance of organizational structures and practices in reinforcing commitment on the part of suicide recruits is an under-explored factor in many (...) analyses. This essay examines the potential applicability of evolutionary models of altruism to the understanding of commitment to suicide on the part of terrorist organizational recruits. Three evolutionary models of sacrificial behavior in nonhuman species and many categories of human behavior are explored cross-organizationally: reciprocity, inclusive fitness theory, and induced altruism. Reciprocal altruism is unlikely to be a major motivator in suicide attacks because the costs exhibited by attackers are too high to be adequately compensated. However, the role of evolved self-deception in perceptions of personal death, and thus of rewards in the afterlife, is potentially illuminating. Inclusive fitness theory can help explain the motivations of attackers because rewards to kin often are offered by organizations to suicide recruits. However, suicide bombers also often act out of revenge for the loss of or injury to relatives, and inclusive fitness theory generally, as well as more specific theoretical models of retaliatory aggression, may not adequately account for the bombers' actions. Predictions from induced altruism theory appear to be well supported because suicide terror organizations tend to be tightly structured around practices intended to maintain and reinforce commitment though the manipulation of kinship-recognition cues.

Evolutionists studying human cooperation disagree about how to best explain it. One view is that humans are predisposed to engage in costly cooperation and punishment of free-riders as a result of culture/gene coevolution via group selection. Alternatively, some researchers argue that context-specific cognitive mechanisms associated with traditional neo-Darwinian self- and kin-maximization models sufficiently explain all aspects of human cooperation and punishment. There has been a great deal of research testing predictions derived from both positions; still, researchers generally agree that more (...) naturalistic data are needed to complement mathematical modeling and laboratory and field experiments. Most of these data have been obtained from small-scale forager and other societies, but modern intentional communities offer another productive source of information. This exploratory study describes context-specific patterns of punishment in 46 American intentional communities that cast doubt on the prediction that people are predisposed to punish free-riders in naturalistic interactions.

Atran & Norenzayan (A&N) fail to address several problems with commitment theory as it relates to non-kin altruism in religious contexts. They (1) provide little support for the contention that religious sacrifices function as signals, (2) do not distinguish between religious specialists and lay believers, and (3) conflate definitions of cooperation and sacrifice.

Evolutionarily-minded scholars working on the most puzzling aspects of human cooperation-one-shot, anonymous interactions among non-kin where reputational information is not available-can be roughly divided into two camps. In the first, researchers argue for the existence of evolved capacities for genuinely altruistic human cooperation, and in their models emphasize the role of intergroup competition and selection, as well as group norms and markers of membership that reduce intragroup variability. Researchers in the second camp explain cooperation in terms of individual-level decision-making facilitated (...) by evolved cognitive mechanisms associated with well-established self- and kin-maximization models, as well as by ‘misfires’ that may result from these mechanisms interacting with novel environments. This essay argues that the manner in which culture provides information that de-anonymizes intragroup strangers suggests that neither evolved capacities for genuine altruism nor widespread misfires are necessary to account for anonymous, one-shot cooperation.

La actividad teórica y la actividad práctica han sido tradicionalmente entendidas como complementarias en el sentido que mediante la actividad teórica el sujeto se apropiaría idealmente de los objetos del mundo externo, mientras que mediante la actividad práctica realizaría sus propias metas subjetivas en el mundo. Sin embargo, dicho modelo plantea un conjunto de graves problemas exegéticos y conceptuales sobre la estructura y significado de la entera filosofía del espíritu de Hegel. En este artículo buscaremos esclarecer qué es a ojos (...) de Hegel lo propiamente específico de la actividad teórica y de la actividad práctica, para, sobre esa base, ofrecer un modelo exegético que logre dar satisfactoriamente cuenta de la particular periodización general que Hegel propone sobre las diferentes formas de actividad del espíritu humano.

Die Vernunft ist für Hegel die Einheit des Subjekts und des Objekts ? anders ausgedrückt: Subjekt zu sein impliziert, die Welt zu erkennen. Die Inhalte, die die Erkenntnistätigkeit spontan findet, »setzen« ihre eigene Erkenntnis nicht, weil die der Erkenntnis gegebenen Inhalte keine »unverursachten Ursachen« oder »unbewegten Beweger« des Erkennens sind. Die Erkenntnisobjekte sind für Hegel sowohl ruhend als auch in Bewegung: Unmittelbarkeit und Vermittlung sind bloße Standpunkte über die Erkenntnistätigkeit. Sich ein absolutes Nichtsein des Erkennens vorzustellen (z.B. durch die Zustimmung (...) zum cartesischen Gedankenexperiment, durch eine philosophische Deutung des psychologischen Phänomens des Unbewusstseins oder durch eine naturalistische Interpretation der Theorie der transzendentalen Subjektivität), verändert grundsätzlich unser Verständnis des Erkenntnisphänomens, weil es das Bedürfnis nach speziellen Gründungsakten erzeugt, die als absolute Ursachen der Erkenntnis fungieren sollen. Anhand von Spinozas Substanzbegriff hält Hegel dagegen das Erkennen für streng genommen unverursacht und insofern die Erkenntnisakte für innere Momente des unendlichen absoluten Elements des Erkennens, d.h. der ununterbrochenen und ununterbrechbaren Geist-Welt-Einheit. Vom Standpunkt des künstlich vorgestellten Nichtseins der Geist-Welt-Einheit muss aber der Kreislauf der Erkenntnisakte irgendwann angefangen haben; das menschliche Erkennen bzw. Denken wird dadurch zum bloß formalen Denken - in Hegels Terminologie: zum »Bewusstsein«. Damit die Tatsache begreiflich wird, dass das Erkennen schon immer einen Inhalt hat, müssen die Bestimmungen einiger Denkakte als Dinge interpretiert werden, die von außen her das Erkennen in Gang setzen und erfüllen. Erst diese hypostasierten Denkakte können die Tatsache erklären, dass der menschliche Geist die Wirklichkeit erkennt; im Gegensatz zu diesen Denkakten, denen das epistemische Privileg verliehen wird, den Geist mit der Welt in Kontakt zu bringen, werden die restlichen Denkakte zu bloß subjektiven Vorstellungen reduziert. In diesem Zusammenhang soll die sinnliche Wahrnehmung oder Empfindung den absoluten Anfang des Erkennens bilden, obwohl sie selber ein Akt und Moment des Denkens ist. Die empirische Erkenntnis soll hier ein in sich leer gewordenes Denken in Kontakt mit der Welt setzen, damit dieses erst dann zum Erkennen dessen wird, was es wirklich gibt. Für Hegel bilden dagegen die empirischen Gegenstände keinen absoluten Anfang der Erkenntnis, sondern sind bereits da im Denken als unendlicher Totalität des erkennenden Geistes und der erkannten Welt. In diesem theoretischen Rahmen gibt es - selbstverständlich! - Raum für sinnliches Erkennen, aber keinen für Empirismus. Aristoteles? Aussage, dass »die Seele in gewisser Weise alle Dinge« ist, und das scholastische Diktum, dass »ens et verum convertuntur«, paraphrasierend, behauptet Hegel: »das Absolute ist der Geist«. (shrink)

Here are crucial data for any theory of the self, self-consciousness or the structure of experience. We discuss the fundamental structure of both indexical reference, especially first-term reference, and quasi-indexical reference, used in attributing first-person reference to others. Chisholm's ingenious account of direct awareness of self is tested against the two sets of data. It satisfies neither. Chisholm's definitions raise serious questions both about philosophical methodology and about the underlying ontology of individuation, identity, and predication. Chisholm's adverbial account of non-physical (...) contents of consciousness is also examined; several questions are raised about the possible success of the linguistic technique of ontological reduction by hyphenation and creation of grammatical devices.

Si bien se han escrito una cantidad relativamente grande de artículos y libros sobre diversos aspectos del pensamiento filosófico de Ignacio Ellacuría, hasta ahora no se cuenta con un sistemático de toda su producción filosófica que muestre la unidad de todos esos aspectos y que defina con claridad lo propio y original de su pensamiento, más allá de lo que pueda haber de la filosofía de Xavier Zubiri, filósofo vasco, de quien Ellacuría fue su amigo y su más estrecho colaborador. (...) Esta investigación se ha realizado con un doble objetico: en primer lugar, analizar y sistematizar los aspectos centrales del pensamiento filosófico de Ignacio de Ellacuría; y, en segundo lugar, estudiar la génesis y constitución de su proyecto filosófico de liberación. Queda de manifiesto cuál es la ubicación y el aporte específico de Ellacuría dentro del conjunto de las principales corrientes de la filosofía de la liberación latinoamericana. (shrink)

Philosophy is the search for the large patterns of the world and of the large patterns of experience, perceptual, theoretical, . . . , aesthetic, and practical - the patterns that, regardless of specific contents, characterize the main types of experience. In this book I carry out my search for the large patterns of practical experience: the experience of deliberation, of recognition of duties and their conflicts, of attempts to guide other person's conduct, of deciding to act, of influencing the (...) physical world with one's doings, and the like. This is the experience that makes possible our social life, the formulation of plans for teamwork, the building of institutions, the development of nations, and the adoption of the ideal of morality. Here I develop a network of theories about the most fundamental aspects of practical thinking: what is thought in such thinking; what makes that thinking correct; what makes it practical; and the structure of the doings that accrue to the world when such thinking is effective. I have attempted to build each theory in sufficient detail, so that it il luminates its subject matter with a certain degree of fullness. But I have also aimed at producing an harmonious system of theories, so that the grand pattern of practical thinking can be admired, not only for the beauty of the separate structures of its parts, but also for its architectonic unity. Chapter 1 gives the details of the many facets of this project and discusses some methodological techniques. (shrink)

Did Jesus ever do anything wrong? Judging by the vast majority of books on New Testament ethics, the answer is a resounding No. Writers on New Testament ethics generally view Jesus as the paradigm of human standards and behaviour. But since the historical Jesus was a human being, must he not have had flaws, like everyone else? The notion of a flawless human Jesus is a paradoxical oddity in New Testament ethics. According to Avalos, it shows that New Testament ethics (...) is still primarily an apologetic enterprise despite its claim to rest on critical and historical scholarship. The Bad Jesus is a powerful and challenging study, presenting detailed case studies of fundamental ethical principles enunciated or practised by Jesus but antithetical to what would be widely deemed 'acceptable' or 'good' today. Such topics include Jesus' supposedly innovative teachings on love, along with his views on hate, violence, imperialism, animal rights, environmental ethics, Judaism, women, disabled persons and biblical hermeneutics. After closely examining arguments offered by those unwilling to find any fault with the Jesus depicted in the Gospels, Avalos concludes that current treatments of New Testament ethics are permeated by a religiocentric, ethnocentric and imperialistic orientation. But if it is to be a credible historical and critical discipline in modern academia, New Testament ethics needs to discover both a Good and a Bad Jesus. (shrink)

The aim of this paper is to explore the interaction between aesthetic properties and cognitive value in serial television. This study is based on a survey focused specifically on one television series: the second season of My Brilliant Friend, created by Saverio Costanzo. The survey was designed with the aim of getting respondents to express their perceptions of the relationship between the aesthetic qualities of the series and their assessment of it in cognitive terms. The responses obtained in the survey (...) offer a clear answer to the key question of concern for this article. The vast majority of respondents (more than 90% in almost all cases) believe that aesthetic and cognitive qualities mutually influence one another. Additionally the qualitative results invite us to further explore interactionism conceptually: the cognitive content is taken as a criterion for evaluating the season’s aesthetic value overall, suggesting a link between meaning and narrative form.

Según una historia estándar, devenida habitual especialmente por influencia del pensamiento heideggeriano, la filosofía occidental se encuentra atrapada en la trampa de la metafísica. La trampa de la metafísica centra la crítica a la metafísica en torno a la tesis según la cual el esencialismo y una concepción de la verdad condicionada por él determinan qué significa “ser” o “existencia”. Detrás de la realidad se supone un fundamento que bajo la forma de un “trasmundo” (Hinterwelt) produce una manifestación cuasi-causal, a (...) saber: el “mundo” (Welt), el cual se deja con ello concebir como la aparición del ser que se ha retraído en sí mismo. La diferencia entre ser y apariencia mantiene al pensamiento metafísico atrapado, en la medida en que éste no es capaz de reconocer esa diferencia misma como una apariencia. En Siete ensayos sobre la muerte de la metafísica, Héctor Ferreiro ofrece frente a esta historia estándar una convincente contrahistoria. Esta contrahistoria tiene su punto de partida en Hegel, quien intenta, de modo opuesto a la lectura propuesta por Heidegger, superar a la metafísica con sus propios medios y sepultarla a partir de su propia dinámica interna. Precisamente a esta superación está dedicado el debate y discusión de Hegel con el argumento ontológico. Como Kant, Hegel ve en el argumento ontológico uno de los centros operacionales de la metafísica clásica. La cuestión es, pues, cómo abordar el argumento ontológico del modo correcto desde un punto de vista crítico a la metafísica. La estrategia que ofrece Hegel consiste, como lo expone Ferreiro, en desenmascarar la distinción misma entre el ser y la apariencia producida por él como una operación de tipo conceptual. Según Hegel, la metafísica ha sido desde siempre el intento por desarrollar una teoría de la totalidad. Pero una teoría de la totalidad que coloca al ser de un lado y a su aparición del otro lado de un límite no advierte su propia operación, dado que el trazado de un límite pertenece él mismo a la teoría de la totalidad. De lo que se trata, pues, es de examinar los trazados de límite constitutivos de la metafísica para reconocerlos como productos de la reflexión y no como hechos dados que el pensamiento tan sólo debe reflejar. El movimiento de autosuperación de la metafísica que culmina en la discusión de Kant y Hegel con el argumento ontológico pertenece ya, sin embargo, a la tradición de la metafísica. Como lo muestra Ferreiro, la metafísica está a más tardar a partir de la distinción medieval entre esencia y existencia en proceso de superarse a sí misma, pues ya Tomás de Aquino logra reconocer en dicha distinción la verdadera fuente de la producción del mundo. Tomás persiste aún, sin embargo, en una concepción sustancialista, en la medida en que considera a la distinción entre esencia y existencia como un hecho in-dependiente de la teoría y del sujeto. Sin embargo, esa distinción es una operación conceptual y no un objeto que se encuentra en el mundo. En esta medida, la tesis de la distinción de razón entre ambas categorías se presenta como un indicador de la reflexión de la metafísica sobre sí misma. Ferreiro demuestra que el célebre comienzo de la Cien-cia de la Lógica de Hegel significa precisamente una profundización y radicalización de esa autorreflexión. Ahora bien, a ojos de Hegel el ser del comienzo de la Lógica es en sí mismo como tal el resultado del argumento ontológico; en su formulación clásica, sin embargo, el argumento ontológico sólo aspira a probar que hay algo (Dios), pero el argumento mismo no es como tal capaz de determinar ulteriormente ese algo –esto constituye justamente la tarea de la ontología en el sentido de Hegel, es decir, la tarea de la Lógica. Así, lo que podría denominarse en Hegel una “metafísica” es expresamente una crítica a la metafísica tradicional. En efecto, la ontología que Hegel propone en modo alguno significa una recaída en la metafísica anterior a Kant; por el contrario, en la filosofía de Hegel metafísica y crítica a la metafísica se vinculan íntimamente y con ello se cierra un círculo que se había abierto en la metafísica teológica de la Edad Media: precisamente que este movimiento estaba contenido ya programáticamente en la ontología de la distinción entre esencia y existencia es algo que Ferreiro analiza en forma clara y meticulosa. En cuanto disciplina, la ontología está hoy nuevamente en el centro de la atención de la reflexión filosófica a nivel mundial. Siete ensayos sobre la muerte de la metafísica no sólo ofrece en este respecto un análisis de índole histórica; es también una importante contribución teórica al actual retorno a la ontología.

This primer on biblical criticism and key problems in religion and philosophy is intended as an introduction to these complex subjects for Spanish-speaking laypersons with little or no prior scientific training in the area. Professor Avalos critically reviews the classic arguments for the existence of God, alleged miracles and faith-healing, the belief that the Bible is the inerrant word of God, problems of good and evil in the Bible, creation stories, biblical prophecy, the resurrection of Jesus, and many other topics. (...) In the last part of the book, Avalos discusses the scientific worldview, especially as it impinges upon the question of the existence of God. A notes section allows readers to explore more deeply the areas touched on in the text; appendices provide information on the sources of many biblical stories and beliefs in Mesopotamian and other ancient Near Eastern cultures; and a final personal note briefly recounts the author’s experiences from his upbringing in fundamentalist Christianity to his current skeptical view. This informative volume is an excellent starting point for those who wish to explore with a minimum of resources basic questions in religion, philosophy, and biblical studies. (shrink)

This article discusses Jacques Rancière's theory of literature as centred on an agonistic concept of literature, where literature is seen as a ‘positive contradiction’. This positive contradiction arises from what Rancière sees as literature's origins in the ‘errant letter’, which is conceived as an intrinsically democratic principle that, for Rancière, also results in the tendency of literature to incarnate the word and to propose an extra-textual truth which would signal the end of literature as democratic errancy. Asking whether it is (...) possible to identify Rancière as ‘taking sides’ in what he sets up as a struggle, the article analyses three examples of Rancière's engagement with literary texts in which he demonstrates the necessity for literature to maintain its constitutive contradiction, resulting in a conception of literature as an agonistic field and as a self-critical mode of writing.

This book describes in detail the relationship between symbolic representations of knowledge and abstract states of knowledge, exploring along the way the foundations of knowledge, knowledge bases, knowledge-based systems, and knowledge representation and reasoning. The idea of knowledge bases lies at the heart of symbolic, or "traditional," artificial intelligence. A knowledge-based system decides how to act by running formal reasoning procedures over a body of explicitly represented knowledge—a knowledge base. The system is not programmed for specific tasks; rather, it is (...) told what it needs to know and expected to infer the rest. This book is about the logic of such knowledge bases. It describes in detail the relationship between symbolic representations of knowledge and abstract states of knowledge, exploring along the way the foundations of knowledge, knowledge bases, knowledge-based systems, and knowledge representation and reasoning. Assuming some familiarity with first-order predicate logic, the book offers a new mathematical model of knowledge that is general and expressive yet more workable in practice than previous models. The book presents a style of semantic argument and formal analysis that would be cumbersome or completely impractical with other approaches. It also shows how to treat a knowledge base as an abstract data type, completely specified in an abstract way by the knowledge-level operations defined over it. (shrink)

En este trabajo se estudia la primera concepción escotista sobre las categorías y sobre el objeto del tratado aristotélico de las Categorías. El artículo se concentra sobre las tres primeras cuestiones del comentario de Duns Escoto al texto de Aristóteles. Una de las novedades del texto es su tematización del concepto mismo de categoría, entendido como concepto lógico y como objeto propio del tratado aristotélico. Esta aproximación permite a Escoto distinguir el orden lógico y el orden metafísico en el tratamiento (...) de las categorías. En el primero, la lógica se ocupa del concepto de categoría y, en el segundo, la metafísica se ocupa de la diversidad categorial y de su referencia a la categoría de la substancia. (shrink)

This article analyzes the analogy made between Intellectus Agens and light, used by Aristotle in De Anima III, 5, commented by Aquinas. The investigation focuses on St. Thomas commentary, mainly on the limits of such analogy. It is shown how Thomas Aquinas is forced, in order to avoid the divinization of the Intellectus Agens, to bring a neoplatonic element to the discussion, incompatible with the Aristotelian spirit. References to the optic theories of Aristotle and Aquinas are made. It is discussed (...) what it means to say that the Intellectus Agens is an act. Finally, it is shown why does the nature of the Intellectus Agens demand an intervention of the Separate Substances. The discussion focuses on the Sententia super De anima, and recurs to other works, mainly: Quaestiones disputatae De Anima, Summa Contra Gentiles, Summa Theologiae, De unitate intellectus contra Averroistas and De substantiis separatis ad fratrem Reginaldum. /// O presente artigo analisa a analogia entre o Intellectus Agens e a luz, analogia essa utilizada por Aristóteles em De anima iii, 5 e comentada por S. Tomás de Aquino. O estudo centra-se no comentário de S. Tomás, insistindo de modo particular nos limites dessa analogia. Em particular, mostra-se de que modo o Aquinate se vê obrigado, para evitar a divinização do Intellectus Agens, a introduzir um elemento neoplatónico, incompatível com o espírito aristotélico. O artigo refere as teorias ópticas de Aristóteles e de S. Tomás. Depois analisa o que significa o Intellectus Agens como acto. Finalmente, mostra por que razão a natureza do Intellectus Agens exige a intervenção das Substâncias Separadas. A discussão está centrada no Sententiae super De anima, mas recorre também a obras como as Quaestiones disputatae De Anima, a Summa Contra Gentiles, a Summa Theologiae, De unitate intellectus contra Averroistas e De substantiis separatis ad fratrem Reginaldum.
