Catholic Social Teaching has taken a remarkable turn with the May 1991 document on economic ethics,Centesimus Annus. During their one hundred year history, church documents were notable for their courageous championing of the rights of the least advantaged; they were much less distinguished for their understanding of how markets and incentives function in capitalism. Most business leaders admired church teaching for its compassion but had little respect for its competence. With this most recent document, however, there is a growing conviction (...) that the church may have come of age in economic ethics. Even theWall Street Journal has celebratedCentesimus Annus. The article outlines the highlights of the document and its points of continuity with the tradition. Responses from business and the academy are also briefly considered. (shrink)

In 1982, Neil Postman wrote The Disappearance of Childhood. In that work, Postman recounted the invention of childhood in the modern world and its demise at the hands of, among other things, the electronic media. In Postman’s view, television had transformed education into ‘edutainment.’ The implications of this loss were devastating. Taking up where Postman left off I wish to reexamine his claim and amend and update his thesis by suggesting that, after the latest electronic turn, we now live in (...) societies where a meaningful conception of adulthood is disappearing. It is disappearing, in part, because of an impoverished conception of citizenship. Yet it is additionally undermined because, claims to the ascendancy of the ‘knowledge worker’ notwithstanding, the fundamental connection between education and employment is unraveling. In this climate, the purposes of education are constantly queried and scrutinized as its telos is redefined by criteria external to the practice of education: cost-effectiveness, value-for-money, and so on. I suggest that only be reclaiming a meaningful conception of adulthood can education be defended and only by so doing can individuals hope to understand the world around them. (shrink)

During the British socialist revival of the 1880s competing theories of evolution were central to disagreements about strategy for social change. In News from Nowhere (1891), William Morris had portrayed socialism as the result of Lamarckian processes, and imagined a non-Malthusian future. H.G. Wells, an enthusiastic admirer of Morris in the early days of the movement, became disillusioned as a result of the Malthusianism he learnt from Huxley and his subsequent rejection of Lamarckism in light of Weismann's experiments on mice. (...) This brought him into conflict with his fellow Fabian, George Bernard Shaw, who rejected neo-Darwinism in favour of a Lamarckian conception of change he called "creative evolution.". (shrink)

This paper presents a review and an historical perspective on the architectural metaphor. It identifies common characteristics and peculiarities—as they apply to given historical periods—and analyses the similarities and divergences. The review provides a vocabulary, which will facilitate an appreciation of existing and new metaphors.

Despite the promises made by molecular evolutionists since the early 1960s that phylogenies would be readily reconstructed using molecular data, the construction of molecular phylogenies has both retained many methodological problems of the past and brought up new ones of considerable epistemic relevance. The field is driven not only by changes in knowledge about the processes of molecular evolution, but also by an ever-present methodological anxiety manifested in the constant search for an increased objectivity—or in its converse, the avoidance of (...) subjectivity.This paper offers an exhaustive account of the methodological and conceptual difficulties embedded in each of the steps required to elaborate molecular phytogenies. The authors adopt a historical perspective on the field in order to follow the development of practices that seek to increase the objectivity of their methods and representations. These include the adoption and development of explicit criteria for evaluation of evidence, and of procedures associated with methods of statistical inference, quantification and automation. All these are linked to an increasing use of computers in research since the mid 1960s. We will show that the practices of objectivity described are highly dependent on the problems and tools of molecular phylogenetics. (shrink)
