Walters analyses Canadian and global information highway policy and practices from a philosophical, human rights framework that views freedom and well-being as the necessary conditions of human action.

Reagan mixes the genres of biographical essay, memoir, philosophical essay, and interview to provide the reader with a fascinating and highly readable account. The biographical essay narrates Ricoeur’s early life, his experience as a POW during the Second World War, professorships at the Sorbonne, Nanterre, and Chicago, and his “rediscovery” in and return to France after the publication of Time and Narrative. Reagan’s analysis betrays Ricoeur’s comment that “no one is interested in my life... [since] my life is my work... (...) my books and my articles.” Ricoeur’s captivity as a prisoner of war, the problems he encountered at Nanterre University as doyen of the Faculty of Letters during the 1960s, and the pain and love he and Simone felt for Olivier, their fourth child who committed suicide, are some of the intriguing and touching elements of the narrative. After Olivier’s tragic death in 1986, Ricoeur added “suffering” to the phrase “human action” whenever he wrote about the problem of human action and suffering. (shrink)

Findlay & Walker give voice to several common lines of thought regarding oculomotor control but do not provide sufficient detail for a critical evaluation of their theory. I argue that arbitrary spatial and temporal saccade metrics can be produced simply by manipulating the initial activation values in their model – values that the authors never specify. This lack of detail makes it difficult to anticipate the model's specific oculomotor behavior, or to compare this behavior to models opting for a more (...) quantitative framework. (shrink)

Given these findings, we argue that each of the most plausible attempts to properly classify bacteriophages into distinct species fail. Mayr's biological species concept fails because there is (...) no useful viral analog to sexual reproduction. Phenetic species concepts fail because they obscure the mosaicism and the rich reticulated viral histories. Phylogenetic species concepts, even when extended to take into account reticulation, fail because there is no non-arbitrary distinction between recombination events that create a new viral species and those that do not. There is good reason to think that bacteriophages, arguably the Earth's most abundant biological agent, evolve without forming species.

In this paper, I argue against John Beatty’s position in his paper “The Evolutionary Contingency Thesis” by counterexample. Beatty argues that there are no distinctly biological laws because the outcomes of the evolutionary processes are contingent. I argue that the heart of the Caspar–Klug theory of virus structure—that spherical virus capsids consist of 60T subunits (where T = k 2 + hk + h 2 and h and k are integers)—is a distinctly biological law even if the existence of spherical (...) viruses is evolutionarily contingent.

This article discusses John Searle’s status function account of human rights and Åsa Burman’s “A Critique of the Status Function Account of Human Rights.” While recognizing the validity of part of the critique, based on the distinction between types and tokens, the author argues that, nonetheless, one is not compelled to accept Burman’s conclusion, that “one must give up the status function account of human rights to explain how a human right can exist without collective recognition”. Specifically, the author accepts (...) Burman’s critique of Searle’s attempt to preserve the intuition that human rights have existed without collective recognition, but concludes offering three ways to understand human rights even in the absence of collective recognition, all of which preserve the status function account.

The recent conception of biodiversity proposed by James Maclaurin and Sterelny was developed mostly with macrobiological life in mind. They suggest that we measure biodiversity by dividing life into natural units (typically species) and quantifying the differences among units using phenetic rather than phylogenetic measures of distance. They identify problems in implementing quantitative phylogenetic notions of difference for non-prokaryotic species. I suggest that if we focus on microbiological life forms that engage in frequent, promiscuous lateral gene transfer (LGT), and their (...) associated reticulated phylogenies, we need to rethink the notion of species as the natural unit, and we discover additional problems with phylogenetic notions of distance. These problems suggest that a phenetic approach based on morphospaces has just as much appeal, if not more, for microbes as they do for multi-cellular life. Facts about LGT, however, offer no new insight into the additional challenge of reconciling units and differences into a single measure of biodiversity. (shrink)

In the Snell-Maehler edition of Bacchylides there is a very comprehensive bibliography, listing almost 300 items concerned with Bacchylides poems. It is significant that 80 per cent of these were written in the first twenty years following Kenyon's publication of the Bacchylides papyri in 1897. Of the articles which have appeared since the First World War, many are concerned with more recent papyrus discoveries and a few are stylistic discussions. For most of the poems dealt with in the pioneering days (...) of Bacchylidean scholarship certain readings of the text and interpretations of it have become canonical. This article aims to show in just one poem, XVII, a few instances in which the accepted interpretations should be re-examined. In some cases new interpretations are offered, but in others older views have been resurrected and bolstered by further argument. (shrink)

This is a reply to Weinfurt's article examining the Sweeping Model. Overall, our positions are not as incompatible as they may seem, although I feel that his conclusion, that the Sweeping Model cannot explain human attention, does not follow from his comments. I will proceed through his article and clarify issues as they arise. Our difference of opinion may result from differing goals, with Weinfurt being concerned with more abstract aspects of cognition, and myself with basic perception and how it (...) may be achieved before proceeding to the more abstract.

_ Source: _Volume 28, Issue 2, pp 132 - 148 A striking feature of Thomas Hobbes’s account of political obligation is his discussion of the Fool, who thinks it reasonable to adopt a policy of selective, self-interested covenant breaking. Surprisingly, scholars have paid little attention to the potential of a psychological defense of Hobbes’s controversial claim that the Fool behaves irrationally. In this paper, I first describe Hobbes’s account of the Fool and argue that the kind of Fool most worth (...) considering is the covert, long-term Fool. Then I advance and critically assess two psychological arguments according to which the Fool’s policy of self-interested covenant breaking is prudentially irrational. The first argument holds that, taken together, the deep guilt from early-stage covenant breaking, the cumulative guilt from continued covenant breaking, and the high statistical risk of detection during high-volume covenant breaking render the Fool’s policy irrational. The second argument holds that the Fool’s policy is irrational because it puts him at risk of adopting a psychologically intolerable view of his fellow covenanters and, specifically, the extent to which they can be trusted.
