Sober and Wilson have recently claimed that evolutionary theory can do what neither philosophy nor experimental psychology have been able to, namely, "break the deadlock" in the egoism vs. altruism debate with an argument based on the reliability of altruistic motivation. I analyze both their reliability argument and the experimental evidence of social psychology in favor of altruism in terms of the folk-psychological "laws" and inference patterns underlying them, and conclude that they both rely on the same patterns. I expose the confusions that have led Sober and Wilson to defend a reliability argument while rejecting the experimental evidence of social psychology.

Altruism is a central concept in evolutionary biology. Evolutionary biologists still disagree about its meaning (E.O. Wilson 2005; Fletcher et al. 2006; D.S. Wilson 2008; Foster et al. 2006a, b; West et al. 2007a, 2008). Semantic disagreement appears to be quite robust and not easily overcome by attempts at clarification, suggesting that substantive conceptual issues lurk in the background. Briefly, group selection theorists define altruism as any trait that makes altruists losers to selfish traits within groups, and makes groups of altruists fitter than groups of non-altruists. Inclusive fitness theorists reject a definition based on within- and between-group fitness. Traits are altruistic only if they cause a direct and absolute fitness loss to the donor. The latter definition is more restrictive and rejects as cases of altruism behaviors that are accepted by the former. Fletcher and Doebeli (2009) recently proposed a simple, direct and individually based fitness approach, which they claim returns to first principles: carriers of the genotype of interest “must, on average, end up with more net direct fitness benefits than average population members.” This seductively simple proposal uses the concept of assortment to explain how diverse kinds of altruists end up on average with more net fitness than their non-altruistic rivals. In this paper I shall argue that their approach implies a new concept of altruism that contrasts with and improves on the concept of the inclusive fitness approach

Recent developments in evolutionary game theory argue the superiority of punishment over reciprocity as accounts of large-scale human cooperation. I introduce a distinction between a behavioral and a psychological perspective on reciprocity and punishment to question this view. I examine a narrow and a wide version of a psychological mechanism for reciprocity and conclude that a narrow version is clearly distinguishable from punishment, but inadequate for humans; whereas a wide version is applicable to humans but indistinguishable from punishment. The mechanism for reciprocity in humans emerges as a meta-norm that governs both retaliation and punishment. I make predictions open to empirical investigation to confirm or disconfirm this view.

Is morality biologically altruistic? Does it imply a disadvantage in the struggle for existence? A positive answer puts morality at odds with natural selection, unless natural selection operates at the level of groups. In this case, a trait that is good for groups though bad for individuals can evolve. Sociobiologists reject group selection and have adopted one of two horns of a dilemma. Either morality is based on an egoistic calculus, compatible with natural selection; or morality continues tied to psychological and biological altruism but not as a product of natural selection. The dilemma denies a third possibility—that psychological altruism evolves as a biologically selfish trait. I discuss the classical treatments of the paradox by Charles Darwin and Robert Trivers, focusing on the role they attribute to social emotions. The upshot is that both Darwin and Trivers sketch a natural-selection process relying on innate emotional mechanisms that render morality adaptive for individuals as well as for groups. I give additional reasons for viewing it as a form of natural, instead of only cultural, selection

RESUMEN Diversos estudios han concluido que los pacientes con daño en la Corteza Frontal -CF- o Corteza Prefrontal Ventromedial -CPV- muestran una disposición a herir directamente a otra persona con el fin de salvar varias vidas en sus respuestas a los "dilemas morales personales", revelando una posible carencia de empatía. No obstante, cuando evalúan conductas carentes de empatía sin justificación utilitarista, sus respuestas son normales. Defendemos aquí que los pacientes sufren una deficiencia cognitiva relacionada con la hipótesis de marcador somático de Damasio y con juicios de valor. Criticamos la hipótesis del "paciente utilitarista", que se ha atrincherado en la neurociencia cognitiva. ABSTRACT In their answers to questions regarding "personal moral dilemmas", patients with lesions to the Frontal Cortex -FC- or Ventromedial Prefrontal Cortex -vmPFC- display a disposition to directly injure another person in order to save lives, thus revealing a possible lack of empathy. However, their answers are normal when they evaluate behaviors lacking in empathy but without a utilitarian justification. We here defend that those patients suffer from a cognitive deficiency associated with Damasio's somatic marker hypothesis and with value judgments. The article critiques the "utilitarian patient" hypothesis that has become deeply rooted in cognitive neuroscience. RESUMO Diversos estudos têm concluído que os pacientes com danos no Córtex Frontal (CF) ou Córtex Pré-frontal Ventromedial (CPV) mostram uma disposição a ferir diretamente a outra pessoa com o objetivo de salvar várias vidas em suas respostas aos "dilemas morais pessoais", o que revela uma possível carência de empatia. Contudo, quando avaliam condutas carentes de empatia sem justificativa utilitarista, suas respostas são normais. Defendemos aqui que os pacientes sofrem uma deficiência cognitiva relacionada com a hipótese de marcador somático de Damásio e com juízos de valor. Criticamos a hipótese do "paciente utilitarista", que vem se refugiando na neurociência cognitiva

Classical evolutionary explanations of social behavior classify behaviors from their effects, not from their underlying mechanisms. Here lies a potential objection against the view that morality can be explained by such models, e.g. Trivers’reciprocal altruism. However, evolutionary theory reveals a growing interest in the evolution of psychological mechanisms and factors them in as selective forces. This opens up perspectives for evolutionary approaches to problems that have traditionally worried moral philosophers. Once the ability to mind-read is factored-in among the relevant variables in the evolution of moral abilities and counted among the selection pressures that have plausibly shaped our nature as moral agents, an evolutionary approach can contribute, so I will argue, to the solution of a long-standing debate in moral philosophy and psychology concerning the basic motivation for moral behavior.

La filosofía se ha preocupado desde susorígenes por el sentido de la vida humana. Estapreocupación es la que subyace a la "Filosofíade la Historia", disciplina que surge en laépoca moderna con la pregunta por la existencia o inexistencia de un progreso en la historia. Autores como Kant consideran que el progreso,para poder valer como tal, ha de aconteceren el terreno de lo moral, sobre todo en sus manifestaciones sociales externas, es decir, enla realización del derecho natural en las formasconcretas de convivencia humana. En su Filosofíade la historia busca Kant argumentosracionales en favor de la existencia de unprogreso de este tipo. El principal obstáculo asus argumentos es la existencia del mal o delo irracional. Kant intenta superarlo argumentandoen favor de una concepción teleológicade la historia, según la cual la humanidadprogresa del mal hacia el bien. En el presente artículo ensayo una reconstrucción de los principales pasos de su argumentación.

Los sociobiólogos han defendido una posición "calvinista" que se resume en la siguiente fórmula: si la selección natural explica las actitudes morales, no hay altruismo genuino en la moral; si la moral es altruista, entonces la selección natural no puede explicarla. En este ensayo desenmascaro los presupuestos erróneos de esta posición y defiendo que el altruismo como equidad no es incompatible con la selección natural. Rechazo una concepción hobbesiana de la moral, pero sugiero su empleo en la interpretación de la psicología de los primates no humanos y en un modelo de progresión evolutiva que habría llevado a la moralidad como adaptación pasando por la razón instrumental.

Se busca rastrear la imagen que Platón tiene de Heráclito y articularla con la estructura argumentativa del Cratilo, para comprender las necesidades textuales a las que responde la doctrina del flujo perpetuo, es decir, la discusión sobre la corrección (ὀρθότης) del nombre. Gracias a la inclusión del testimonio heraclíteo, resulta posible rastrear la presunta consolidación de la tesis sobre los nombres primarios y los secundarios como el eje de la separación entre dos planos de realidad (uno estable y uno móvil) y de la teoría de las Ideas -es decir, como la base de la epistemología platónica presente en los diálogos de madurez-. The article seeks to trace the image Plato has of Heraclitus and connect it with the argumentative structure of the Cratylus in order to understand the textual needs that give rise to the doctrine of perpetual flux, that is, the discussion regarding the correctness (ὀρθότης) of names. The inclusion of Heraclitus's testimony makes it possible to trace the alleged consolidation of the thesis regarding primary and secondary names as the axis of separation between two levels of reality (one stable, the other, changing) and the theory of Ideas -that is, as the basis of Plato's epistemology as set forth in the late dialogues-
