Sartre's moral thinking progressed from an abstract, idealistic ethics of authenticity to a more concrete, realistic, and materialistic morality. Much of Sartre's important unpublished work on ethics - relevant to both his 'first' and his 'second' ethics - has become available to scholars only in the years since his death. Only now has it become possible to give a complete presentation of both the first and the second ethics and to accurately identify their relationship. Sartre's Two Ethics also presents Professor (...) Anderson's original criticisms of Sartre's two ethics, and concludes that the second is a significant advance over the first. (shrink)

This essay explores how the scientific community interpreted the discoveries of extinct giant birds during the mid-nineteenth century on the islands of New Zealand and Madagascar. It argues that the Aepyornis of Madagascar was understood through the moa of New Zealand because of the rise of global networks and theories. Indeed, their global connections made giant birds a sensation among the scientific community and together forged theories and associations not possible in isolation. In this way, this paper argues for a (...) closer look at how the creation of science emerged from a world framework that involved multiple sites of discovery and interpretation that continually influenced and reshaped scientific theories. It also stresses the importance of local naturalists in participating in this global exchange of knowledge. (shrink)

Ocean biology helps regulate global climate by fixing atmospheric CO2 and exporting it to deep waters as sinking detrital particles. New observations demonstrate that particle fragmentation is the principal factor controlling the depth to which these particles penetrate the ocean's interior, and hence how long the constituent carbon is sequestered from the atmosphere. The underlying cause is, however, poorly understood. We speculate that small, particle‐associated copepods, which intercept and inadvertently break up sinking particles as they search for attached protistan prey, (...) are the principle agents of fragmentation in the ocean. We explore this idea using a new marine ecosystem model. Results indicate that explicitly representing particle fragmentation by copepods in biogeochemical models offers a step change in our ability to understand the future evolution of biologically‐mediated ocean carbon storage. Our findings highlight the need for improved understanding of the distribution, abundance, ecology and physiology of particle‐associated copepods. (shrink)

Argues that Aquinas's views on intelligible matter and abstraction, as they relate to mathematics, are considerably more developed than those of Aristotle.

Sinking organic particles transfer ∼10 gigatonnes of carbon into the deep ocean each year, keeping the atmospheric CO2 concentration significantly lower than would otherwise be the case. The exact size of this effect is strongly influenced by biological activity in the ocean's twilight zone (∼50–1,000 m beneath the surface). Recent work suggests that the resident zooplankton fragment, rather than ingest, the majority of encountered organic particles, thereby stimulating bacterial proliferation and the deep‐ocean microbial food web. Here we speculate that this (...) apparently counterintuitive behaviour is an example of ‘microbial gardening’, a strategy that exploits the enzymatic and biosynthetic capabilities of microorganisms to facilitate the ‘gardener's’ access to a suite of otherwise unavailable compounds that are essential for metazoan life. We demonstrate the potential gains that zooplankton stand to make from microbial gardening using a simple steady state model, and we suggest avenues for future research. (shrink)

The question of personal immortality is a central one for Gabriel Marcel. Early in his life he took part in parapsychological experiments which convincedhim that one could, rarely and with great difficulty, communicate with the dead. In a philosophical vein he argued that each self has an eternal dimension which isof eternal worth. This dimension is particularly manifest in self-sacrifice, where I find it meaningful to give my life for another and when I unconditionally commitment myself in love to another (...) self. Marcel also cites the experience of trust or hope, and the experience that life is not an absurd freak accident of nature destined for eternal extinction but rather possesses absolute meaning and value. Yet, none of the above experiences involves certitude; one remains free to accept or reject them and what they claim to involve. (shrink)

Le relatif silence de Bergson au sujet de la figure de Hegel n’empêche pas G. Deleuze de structurer son approche du bergsonisme autour d’un axe résolument anti-hégélien. Notre étude vise à prendre à rebours cette démarche et à dégager un rapport moins antagonique entre bergsonisme et hégélianisme en investiguant en amont de sa reconstruction deleuzienne. Le lieu où la pensée de Bergson diverge le plus profondément de celle de son prédécesseur allemand ne peut à notre avis être identifiéque sur la (...) base d’un accord plus fondamental entre les deux philosophes. Il s’agira ainsi de circonscrire ce terrain d’entente à partir de leur refus commun et assumé du « scepticisme » métaphysique kantien. Il s’avérera que Bergson et Hegel participent d’une tentative similaire pour composer avec la fluidité du réel et qu’ils se heurtent tous deux aux mêmes difficultés pour dire l’absolu sans trahir la vie qui lui est propre.

Many who speak glowingly about the possibilities for human relations in cyberspace, or virtual communities, laud them precisely because such communities are to a great extent free of the real spatial-temporal restrictions rooted in the limitations of our bodies. In this paper I investigate the importance of the body in establishing and maintaining human relations by considering the thought of the twentieth century French philosopher Gabriel Marcel. Because Marcel emphasized the central importance of the body in one's personal self-identity as (...) well as in initiating and maintaining intersubjective bonds in human communities, he is able to offer some interesting reflections on the character of virtual communities. I suggest that a number of the features of cyberspace and its communities that make it attractive to many are precisely the characteristics that Marcel would consider detrimental to establishing intimate lasting human communities. I conclude by indicating why I think that Marcel would be concerned that certain trends in our high tech culture may well lead many to prefer ``living'' in virtual, rather than real communities.
