Don Isaac Abravanel was one of the main leaders of medieval Spanish Jewry. This work presents a systematic exposition of Abravanel's defence of Judaism, analyzing and evaluating his views on the basic issues of medieval philosophy and theology.

Howard J. Curzer presents a fresh new reading of Aristotle's Nicomachean Ethics, which brings each of the virtues alive. He argues that justice and friendship are symbiotic in Aristotle's view; reveals how virtue ethics is not only about being good, but about becoming good; and describes Aristotle's ultimate quest to determine happiness.

In this chapter I defend a methodological view about how we should conduct substantive ethical inquiries in the fields of normative and practical ethics. I maintain that the direct plausibility and implausibility of general ethical principles – once fully clarified and understood – should be foundational in our substantive ethical reasoning. I argue that, in order to expose our ethical intuitions about particular cases to maximal critical scrutiny, we must determine whether they can be justified by directly plausible principles. To (...) expose apparently plausible principles to maximal critical scrutiny, we must determine whether their direct plausibility can survive careful clarification of what they are really saying. This means that intuitions about cases are useful only in (a) suggesting principles that must stand on their own two feet, and (b) illustrating or otherwise helping us clarify what a principle is really saying. We should not reject principles that seem most directly plausible after we have fully clarified their content simply because they conflict with our intuitions about cases, because to do so is to side with uncritical prejudices over the teachings of critical scrutiny.

Some incompatibilists about free will or moral responsibility and determinism would abandon their incompatibilism were they to learn that determinism is true. But is it reasonable to flip-flop in this way? In this article, we contend that it is and show what follows. The result is both a defense of a particular incompatibilist strategy and a general framework for assessing other cases of flip-flopping.

Although the advantages of flight at high altitude were early recognized, so also were the physiological problems standing in the way of its realization. The idea of surmounting such problems by means of a pressurized cabin was advocated as early as 1909, while the first attempt to translate the concept into actuality occurred in 1921. Neither it nor several successive attempts enjoyed any real success until a project launched by the U. S. Air Corps in 1935 produced a breakthrough aircraft (...) designated the XC-35. The major reason for the favorable termination of that venture was the thoroughness of the engineering involved. But it is equally notable that this was the first instance in the age of powered flight where there was an active collaboration between the scientists and engineers, a rather curious circumstance in view of the fact that the achievement of altitude record-setting balloon flights in the nineteenth century had owed a great deal to an interconnection of aeronauts and scientists' laboratories. This paper focuses on the physiological investigations which informed the XC-35 engineers while at the same time bringing into being a new aeromedical laboratory taking the first small step toward turning aeromedicine into space medicine.

Targeted hypermutation has proven to be a useful survival strategy for bacteria under severe stress and is also used by multicellular organisms in specific instances such as the mammalian immune system. This might appear surprising, given the generally observed deleterious effects of poor replication fidelity/high mutation rate. A previous theoretical model designed to explore the role of replication fidelity in the origin of life was applied to a simulated hypermutation scenario. The results confirmed that the same model is useful for (...) analyzing hypermutation and can predict the effects of the same parameters (survival probability, replication fidelity, mutation effect, and others) on the survival of cellular populations undergoing hypermutation as a result of severe stress.

Some rules seem more important than others. The moral rule to keep promises seems more important than the aesthetic rule not to wear brown with black or the pool rule not to scratch on the eight ball. A worrying number of metaethicists are increasingly tempted to explain this difference by appealing to something they call “authoritative normativity” – it’s because moral rules are “authoritatively normatively” that they are especially important. The authors of this chapter argue for three claims concerning “authoritative (...) normativity”: (1) that motivation for it originates in a parochial conception of “normative flavours”; (2) that arguments against alternative ways of explaining e.g., morality’s importance are overblown; and (3) that there are strong reasons against theorizing in terms of “authoritative normativity”. The overarching aim is not to show that “authoritative normativity” is incoherent or entirely unmotivated. Rather, it is to discuss some of “authoritative normativity’s” deeper commitments to correct the impression that is it largely benign or that it is entailed by familiar and popular “metanormative” positions. Authoritative normativity, it seems to us, is a solution in search of a problem. (shrink)

Evolution in modern life requires high replication fidelity to allow for natural selection. A simulation model utilizing simulated phenotype data on cellular probability of survival was developed to determine how self-replication fidelity could evolve in early life. The results indicate that initial survivability and replication fidelity both contribute to overall fitness as measured by growth rates of the cell population. Survival probability was the more dominant feature, and evolution was possible even with zero replication fidelity. A derived formula for the (...) relationship of survival probability and replication fidelity with growth rate was consistent with the simulated empirical data. Quantitative assessment of continuity and other evidence was obtained for a saltation evolutionary process starting from low to moderate levels of survival probability and self-replication fidelity to reach the high levels seen in modern life forms.

The key word in amy account of the different ways that visual details are presented by novels and films is "assert." I wish to communicate by that word the force it has in ordinary rhetoric: an "assertion" is a statement, usually an independent sentence or clause, that something is in fact the case, that it is a certain sort of thing, that it does in fact have certain properties or enter into certain relations, namely, those listed. Opposed to asserting there (...) is mere "naming." When I say, "The cart was tiny; it came onto the bridge," I am asserting that certain property of the cart of being small in size and that certain relation of arriving at the bridge. However, when I say "The green cart came onto the bridge," I am asserting nothing more than its arrival at the bridge; the greenness of the cart is not asserted but slipped in without syntactic fuss. It is only named. Textually, it emerges by the way. Now, most film narratives seem to be of the latter textual order: it requires special effort for films to assert a property or relation. The dominant mode is presentational, not assertive. A film doesn't say, "This is the state of affairs," it merely shows you that state of affairs. Of course, there could be a character or a voice-over commentator asserting a property or relation; but then the film would be using its sound track in much the same way as fiction uses assertive syntax. It is not cinematic description but merely description by literary assertion transferred to film. Filmmakers and critics traditionally show disdain for verbal commentary because it explicates what, they feel, should be implicated visually. So in its essential visual mode, film does not describe at all but merely presents; or better, it depicts, in the original etymological sense of that word: renders in pictorial form. I don't think that this is mere purism or a die-hard adherence to silent films. Film attracts that component of our perceptual apparatus which we tend to favor over the other senses. Seeing, after all, is believing. Seymour Chatman, professor in the department of rhetoric at the University of California, Berkeley, is the author of The Later Style of Henry James and Story and Discourse: Narrative Structure in Fiction and Film.
