This book offers an important study of Aristotle's theory of the sense-organs. It aims to answer two questions central to Aristotle's psychology and biology: why does Aristotle think we have sense-organs, and why does he describe the sense-organs in the way he does? The author looks at all the Aristotelian evidence for the five senses and shows how pervasively Aristotle's accounts of the sense-organs are motivated by his interest in form and function. The book also engages with the celebrated problem (...) of whether perception for Aristotle requires material changes in the perceiver. It argues that, surprisingly to the modern philosopher, nothing in Aristotle's description of the sense-organs requires us to believe in such changes. (shrink)

The Gouldian argument for evolutionary contingency found in Wonderful Life can be dissected into three premises: palaeontological, macro-evolutionary, and developmental. Discussions of evolutionary contingency have revolved primarily around the developmental. However, a shift in methodological practice and new palaeontological evidence subsequent to the book’s publication appears to threaten the palaeontological premise that asserts high Cambrian disparity, or, roughly, that morphological differences between the Cambrian species were high. This presents a prima facie problem: Did the Cambrian consist of enough anatomical variety (...) to fuel a different outcome upon a replay of the tape of life? I investigate the role that disparity plays in the Gouldian argument for evolutionary contingency and conclude that the reduced disparity view does not undermine the argument, per se. As for the macro-evolutionary premise, Gould never offers any explicit justification for the idea that species sorting was indiscriminate or ‘lottery-like’ (though he certainly gestures at it). Putting aside the exegetical, I consider certain empirical avenues for underwriting the macro-evolutionary premise and argue that the most plausible route is to appeal to the special status of mass extinctions, a move that is not entirely unfamiliar to macro-evolutionists. That is, mass extinctions can be good sources of contingency due to their being ‘chancy’ in at least three respects. In sum, I update the palaeontological and macro-evolutionary premises as to reconstrue the Gouldian argument for evolutionary contingency in its strongest form. (shrink)

Ethicists have tended to treat the psychology of attributing mental states to animals as an entirely separate issue from the moral importance of animals’ mental states. In this paper I bring these two issues together. I argue for two theses, one descriptive and one normative. The descriptive thesis holds that ordinary human agents use what are generally called phenomenal mental states to assign moral considerability to animals. I examine recent empirical research on the attribution of phenomenal states and agential states (...) to argue that phenomenal mental states are the primary factor, psychologically, for judging an animal to be morally considerable. I further argue that, given the role of phenomenal states in assigning moral considerability, certain theories in animal ethics will meet significant psychological resistance. The normative thesis holds that ethicists must take the psychology of attributing mental states into account when constructing moral ideals concerning animals. I draw from the literature in political philosophy on ideal and non-ideal theory to argue that non-ideal theories for animals must account for human psychology because—like current social and political conditions—human psychology limits the achievement of moral ideals.

The term “mental illness” implies that persons with such illnesses are more likely to be dangerous to themselves and/or others than are persons without such illnesses. This is the source of the psychiatrist’s traditional social obligation to control “harm to self and/or others,” that is, suicide and crime. The ethical dilemmas of psychiatry cannot be resolved as long as the contradictory functions of healing persons and protecting society are united in a single discipline.Life is full of dangers. Our highly developed (...) consciousness makes us, of all living forms in the universe, the most keenly aware of, and the most adept at protecting ourselves from, dangers. Magic and religion are mankind’s earliest warning systems. Science arrived on the scene only about 400 years ago, and scientific medicine only 200 years ago. Some time ago I suggested that “formerly, when religion was strong and science weak, men mistook magic for medicine; now, when science is strong and religion weak, men mistake medicine for magic”.1We flatter and deceive ourselves if we believe that we have outgrown the apotropaic use of language .Many people derive comfort from magical objects , and virtually everyone finds reassurance in magical words . The classic example of an apotropaic is the word “abracadabra,” which The American Heritage Dictionary of the English Language defines as “a magical charm or incantation having the power to ward off disease or disaster”. In the ancient world, abracadabra was a magic word, the letters of which were arranged in an inverted pyramid and worn as an amulet around the neck to protect the wearer against disease or trouble. One fewer letter appeared in each line of the pyramid, until only the letter “a” remained to form the vertex of the triangle. As …. (shrink)

This “Legal Briefing” column covers recent legal developments involving patient decision aids. This topic has been the subject of recent articles in JCE. It is included in the 2010 Patient Protection and Affordable Care Act. And it has received significant attention in the biomedical literature, including a new book, a thematic issue of Health Affairs, and a recent article in the New England Journal of Medicine. Moreover, physicians and health systems across the United States are increasingly integrating decision aids into (...) their clinical practice. Both federal and state laws play a significant role in promoting this expanded use. On the other hand, concerns about liability could stymie development and implementation. We categorize legal developments concerning patient decision aids into the following five sections:1. Development of decision aids2. Effectiveness of decision aids3. Federal regulation of decision aids4. State regulation of decision aids5. Legal concerns regarding decision aids. (shrink)

En sus Escolios, Nicolás Gómez Dávila hace manifiesta la relación existente entre las antiguas nociones gnósticas y las pretensiones ilustradas de la modernidad. Al determinar los fundamentos del gnosticismo en un conocimiento que se eleva sobre la fe, ubica rasgos análogos en el pensamiento moderno..

The extension of quantum mechanics to a general functional space (“rigged Hilbert space”), which incorporates time-symmetry breaking, is applied to construct extract dynamical models of entropy production and entropy flow. They are illustrated by using a simple conservative Hamiltonian system for multilevel atoms coupled to a time-dependent external force. The external force destroys the monotonicity of the ℋ-function evolution. This leads to a model of the entropy flow that allows a steady nonequilibrium structure of the emitted field around the unstable (...) particles. (shrink)

Saint-Pierre's European Union, an alternative to the balance of power system and a safeguard against universal monarchy, was based on abolition of state sovereignty. Beyond the law of nations, the Union was to ensure European domination of the world and the use of the world's resources in Europe's own interest. A first step towards this goal was a universal crusade to ‘chase the Turk out of Europe and even out of Asia and Africa’. In this, Saint-Pierre followed the logic of (...) Western irenism. (shrink)

Traditionally, plant viruses are viewed as harmful, undesirable pathogens. However, their genomes can provide several useful ‘designer functions’ or ‘sequence modules’ with which to tailor future gene vectors for plant or general biotechnology.The majority (77 %) of known plant viruses have single‐stranded RNA of the messenger (protein coding) sense as their genetic material. Over the past 4 years, improved in vitro transcription systems and the construction of partial of fulllength DNA copies of several plant RNA viruses have enhanced our ability (...) to manipulate and study their genomes, particularly in the context of their pathogenic interactions with host plants.Recently, two forms of genetically engineered protection against plant virus infections have been reported. In both, a virus‐related ‘interfering’ molecule was stably introduced into plants via the DNA‐transfer mechanism of Agro‐bacterium tumefaciens. To date, the choice of ‘interfering’ molecule has been guided by empirical field‐observations and each is effective against only a narrow range of closely‐related viruses. As yet, we do not fully understand the molecular mechanism(s) responsible for the observed protection.The ability to manipulate the plant–pathogen relationship is a powerful tool to increase our knowledge and improve future strategies for uncoventional cropprotection by genetic engineering techniques.
