In "Upheavals of Thought", Martha Nussbaum offers a theory of the emotions. She argues that emotions are best conceived as thoughts, and she argues that emotion-thoughts can make valuable contributions to the moral life. She develops extensive accounts of compassion and erotic love as thoughts that are of great moral import. This paper seeks to elucidate what it means, for Nussbaum, to say that emotions are forms of thought. It raises critical questions about her conception of the structure of emotion, (...) and about her conception of compassion, in particular. Finally, the paper seeks to show how analyzing the structure, as well as the moral value, of the emotions ultimately requires entering the realm of religious ethics. (shrink)

Should laws about sex and pornography be based on social conventions about what is disgusting? Should felons be required to display bumper stickers or wear T-shirts that announce their crimes? This powerful and elegantly written book, by one of America's most influential philosophers, presents a critique of the role that shame and disgust play in our individual and social lives and, in particular, in the law.Martha Nussbaum argues that we should be wary of these emotions because they are associated in (...) troubling ways with a desire to hide from our humanity, embodying an unrealistic and sometimes pathological wish to be invulnerable. Nussbaum argues that the thought-content of disgust embodies "magical ideas of contamination, and impossible aspirations to purity that are just not in line with human life as we know it." She argues that disgust should never be the basis for criminalizing an act, or play either the aggravating or the mitigating role in criminal law it currently does. She writes that we should be similarly suspicious of what she calls "primitive shame," a shame "at the very fact of human imperfection," and she is harshly critical of the role that such shame plays in certain punishments.Drawing on an extraordinarily rich variety of philosophical, psychological, and historical references--from Aristotle and Freud to Nazi ideas about purity--and on legal examples as diverse as the trials of Oscar Wilde and the Martha Stewart insider trading case, this is a major work of legal and moral philosophy.

A model is presented to account for the natural selection of what is termed reciprocally altruistic behavior. The model shows how selection can operate -against the cheater (non-reciprocator) in the system. Three instances of altruistic behavior are discussed, the evolution of which the model can explain: (1) behavior involved in cleaning symbioses; (2) warning cries in birds: and (3) human reciprocal altruism. Regarding human reciprocal altruism, it is shown that the details of the psychological system that regulates this altruism can (...) be explained by the model. Specifically, friendship,d islike, moralistic aggression, gratitude, sympathy, trust, suspicion, trustworthiness, aspects of guilt, and some forms of dishonesty and hypocrisy can be explained as important adaptations to regulate the altruistic system. Each individual human is seen as possessing altruistic and cheating tendencies, the expression of which is sensitive to developmental variables that were selected to set the tendencies at a balance appropriate to the local social and ecological environment.

Some have supposed that morality has its basis in altruistic emotions implanted in accordance with the standard principles of natural selection. It is argued, to the contrary, that the falsity of group selection theory precludes founding genuine altruism on such a basis, and that the correct theory of evolution renders morality possible only if a cognitivist conception of moral psychology is accepted. Some independent reasons are given for favouring that conception over its noncognitivist rival. Morality is then claimed to be (...) a necessary corollary of advanced intelligence, so that morality cannot easily be selected against. Finally, the bearing of the foregoing considerations on the normative contention commonly labelled 'species-ism' is assessed; it is concluded that a proper view of morality suggests the inclusion of (other) animals within its domain of concern.

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. /// Sociobiologists have endorsed a "Calvinist" position captured in the following formula: if natural selection explains moral attitudes, morality is not genuinely altruistic; if morality is altruistic, then natural selection cannot explain it. I expose the false presuppositions behind this claim and argüe that altruism as fairness is not incompatible with natural selection. I reject a Hobbesian view of morality as an instrumental endorsement of fairness norms, but suggest its use to interpret primate psychology and to model an evolutionary progression ending in moral capacities as adaptations.

A perfectly matched layer (PML) absorbing material composed of a uniaxial anisotropic material is presented for the truncation of finite-difference time-domain (FDTD) lattices. It is shown that the uniaxial PML material formulation is mathematically equivalent to the perfectly matched layer method published by Berenger (see J. Computat. Phys., Oct. 1994). However, unlike Berenger's technique, the uniaxial PML absorbing medium presented in this paper is based on a Maxwellian formulation. Numerical examples demonstrate that the FDTD implementation of the uniaxial PML medium (...) is stable, equal in effectiveness as compared to Berenger's PML medium, while being more computationally efficient.
