Six African countries participated in an intercontinental professional development workshop developed by the science and math staff at the University of Iowa and supported by the Africa-America Institute. The 11-day workshop was designed to produce changes in goal setting, assessment practices, instruction, and curriculum structures for high school teachers. The article provides a detailed description of the workshop and discusses evidence of workshop successes. Preworkshop and postworkshop vision statements and curriculum units were used to track the progression of five Kenyan (...) educators as they moved toward constructivist-based practices. Teachers enhanced their views of science and math learning outcomes and learning environment as the workshop progressed. Specifically, teachers moved from emphasizing better grades and exam scores to greater student use of science and math skills. They also shifted from a heavily teacher-centered classroom view to a more student-centered classroom view. (shrink)

Utilitarianism, the great reforming philosophy of the nineteenth century, has today acquired the reputation for being a crassly calculating, impersonal philosophy unfit to serve as a guide to moral conduct. Yet what may disqualify utilitarianism as a personal philosophy makes it an eminently suitable guide for public officials in the pursuit of their professional responsibilities. Robert E. Goodin, a philosopher with many books on political theory, public policy and applied ethics to his credit, defends utilitarianism against its critics and (...) shows how it can be applied most effectively over a wide range of public policies. In discussions of such issues as paternalism, social welfare policy, international ethics, nuclear armaments, and international responses to the environment crisis, he demonstrates what a flexible tool his brand of utilitarianism can be in confronting the dilemmas of public policy in the real world.

In this strikingly original book, one of the leading scholars in the field focuses on the influential idea of deliberative democracy. Goodin examines the great challenge of how to implement the deliberative ideal among millions of people at once and comes up with a novel solution: 'democratic deliberation within'.

Revisioning macro-democratic processes in light of the processes and promise of micro-deliberation, Innovating Democracy provides an integrated perspective on democratic theory and practice after the deliberative turn.

Discusses the justification for a minimal welfare state independent of political rhetoric from the right or the left.

William Whewell is considered one of the most important nineteenth-century British philosophers of science and a contributor to modern philosophical thought, particularly regarding the problem of induction and the logic of discovery. In this volume, Robert E. Butts offers selections from Whewell's most important writings, and analysis of counter-claims to his philosophy.

Presentism states that everything is present. Crucial to our understanding of this thesis is how we interpret the ‘is’. Recently, several philosophers have claimed that on any interpretation presentism comes out as either trivially true or manifestly false. Yet, presentism is meant to be a substantive and interesting thesis. I outline in detail the nature of the problem and the standard interpretative options. After unfavourably assessing several popular responses in the literature, I offer an alternative interpretation that provides the desired (...) result. This interpretation is then used to clarify the distinction between ‘real change’ from mere variation and temporal relativisation. Reflecting on my solution, I try to diagnose the source of confusion over these issues. Then, building upon Fine’s distinction between ontic and factive presentism, I elucidate what the presentist thesis specifically concerns and how best to formalise it. In the process I distinguish a weak and strong version of the presentist thesis. Finally, I end by drawing out some limitations of the paper. (shrink)

If all reasonable people of goodwill and patience will eventually reachconsensus, then anyone who fails to join inthat consensus as being unreasonable or lackingin good will or patience. The ``nice''''(consensual) and ``nasty'''' (intolerant) faces ofcommunitarianism are thus joined. This articleattempts to deny communitarians that excuse forintolerance by undermining Keith Lehrer''s proofof the inevitability of rational consensusamong all patient people of good will.

Este artigo compara e contrapõe a abordagem naturalista pragmatista para a peculiaridade da linguagem, exemplificada, principalmente, mas, não exclusivamente, por John Dewey, com a extensa abordagem de Charles Taylor em seu O animal linguístico. Taylor, inspirado pelas obras de Hamann, Herder, e Humboldt, conta com recursos filosóficos e conceituais diferentes para o delineamento do que ele denomina de ‘a forma’ da capacidade linguística humana. Porém, Dewey e Taylor chegam a posições que se sobrepõem sem se identificar: a linguagem é a (...) característica definidora constitutiva dos seres humanos. Seres humanos são definidos pelo surgimento da ‘como’ consciência, uma ‘ruptura’ em nossa imersão imediata no mundo, e, como Peirce e Dewey mostraram de maneira tão lúcida, um reflexivo estar consciente do uso de signos e sistemas de signos de todos os tipos. Esses sistemas potencializam e transformam nosso acesso ao mundo e a nós mesmos. Eles não apenas rotulam um mudo já existente. Eles criam âmbitos de significados e valores que não surgiram sem eles. A distinção crucial de Taylor entre os modelos designativo e constitutivo da linguagem é apoiada plenamente pela consideração pragmatista da linguagem, a qual Taylor não declara. Essa distinção mostrará ser de importância especial para Dewey e Taylor na criação de paisagens existencialmente vitais de significado incorporados nas autodescrições e nas práticas delicadas das artes de auto-reflexão. Tanto Dewey quanto Taylor mostram que assim como as texturas abertas da experiência crescem por suas extremidades, assim a própria linguagem possui sua própria “extremidade” e nos aponta para os domínios “liminares” que sustentam o limiar do sentido para além do totalmente dizível. Esses domínios, que eles mostram de maneiras diferentes mas complementares, são acessados como realidades por formas não discursivas que abrangem as obras de arte, o que Taylor denomina de ‘representações,’ e rituais performativos e restaurativos, tanto pessoais, cívicos e religiosos que incorporam os significados. Dewey e Taylor, divergem, entretanto, sobre se e de que maneira estes domínios precisam transcender a natureza. (shrink)

This paper firstly distinguishes between principles of “global justice” that apply the same anywhere and everywhere – Tännsjö’s utilitarianism, egalitarianism, prioritarianism and such like – and principles of “local justice” that apply within the specific sphere of health-care. Sometimes the latter might just be a special case of the former – but not always. Secondly, it discusses reasons, many psychological in nature, why physicians might devote excessive resources to prolonging life pointlessly, showing once again that those reasons might themselves be (...) morally significant.

Many large corporations now have written codes of ethics to guide the business/marketing activities of employees. The purpose of this study was to determine the frequency and types of topics which are covered in the ethics policy statements of large U.S. corporations. The results indicated that the topics covered most often (respectively) were: misuse of funds/improper accounting, conflicts of interest, political contributions, and confidential information. It is concluded that in addition to written ethics policy statements, top management should communicate ethical (...) values and demonstrate by example. (shrink)

The respondent agrees with William Grassie that many windows on nature are possible; that emphasis must remain on the generation of order; that “chance” would better be recast as “contingency”; and that the ecological metaphysic has wide implications for a “politics of nature”. He accepts the challenge by Pedro Sotolongo to extend his metaphysic into the realm of pan-semiotics and agrees that an ecological perspective offers the best hope for solving the world’s inequities. He replies to Stanley Salthe that he (...) now agrees that the second law of thermodynamics is the overarching law of nature, but only when the duality inherent in of the concept of entropy is widely recognized. The respondent is enthusiastic over Jeffrey Lockwood’s extrapolation of process ecology to include the concept of “species” and over John Haught’s description of how the construct paves the way for a “theology of evolution” by recasting evolution as an unfolding “drama”.

Este artigo começa com uma afirmação de Dewey que retirada do contexto consiste no maior desastre que o pensamento filosófico pode incorrer. Ela explora o valor heurístico da noção de Dewey de um contexto não apenas para a filosofia, mas para o pensamento e a vida como um todo. Contextos possuem poder existencial profundo tanto que os temos encarnados em nós mesmos. Contextos funcionam como panos de fundo, conforme determinam embasamentos, influenciando de maneira ampla como ante-estruturas de nossas formas de (...) sentimentos, nossos padrões de ação, e os idiomas nos quais nos descrevemos, bem como nossos mundos. Dewey também pensa em contextos como espécies de atmosferas ou brumas, conectando-os com as qualidades determinantes das situações problemáticas nas quais nós nos encontramos. Sustento o argumento de Dewey com ferramentas analíticas fornecidas pela análise da encarnação e da natureza tácita de premissas de Michael Polanyi, e pela exploração da noção de atmosferas e espaços harmonizados de Gernot Böhme. O reconhecimento dos diversos tipos de contextos, nos quais as pessoas vivem e a partir das quais elas falam, é essencial para chegarmos aos tipos de confiança que reduzem o apelo à força e possibilitam acordos em significados comuns enquanto reconhecem as raízes existenciais da diferença.

What general conclusions can be drawn about the reception of zymase, its relation to the larger shift from a protoplasm to an enzyme theory of life, and its status as a social phenomenon?The most striking and to me unexpected pattern is the close correlation between attitude toward zymase and professional background. The disbelief of the fermentation technologists, Will, Delbrück, Wehmer, and even Stavenhagen, was as sharp and unanimous as the enthusiasm of the immunologists and enzymologists, Duclaux, Roux, Fernback, and Bertrand, (...) and of Pfeffer, the experimental plant physiologist. Other skeptics—Voit, Kupffer, and Fischer—were conservatives in traditional fields. In all these cases it seems clear that professional commitments and outlook profoundly influenced the reception of zymase.In some cases there is a correlation with a specific earlier statement favoring the protoplasm theory or predicting a fermentation enzyme. Reynolds Green is a striking case of both. In 1893 he stated his belief that life processes in higher plants and fungi were identical, both being mediated by protoplasm.109 Thus he claimed that digestion was not carried out by enzymes, as in higher animals, but by the whole protoplasm, and so too fermentation in yeast: “All the metabolic processes must be carried out in the unicellular organism in the same mass of protoplasm.”110 But Green also insisted that there was no essential difference between “organized” and “unorganized ferments”; enzymes were simply more highly differentiated and specialized forms of primitive protoplasm. He spoke of “the alcoholic ferment” (that is, enzyme), and of intracellular enzymes—very advanced beliefs for 1893. Thus it is understandable why Green saw no reason to doubt his first negative results with yeast juice, and rushed into print. But it is also understandable that he persisted and soon became an outspoken advocate of Buchner's view; like Wroblewski and Pfeffer, he had already accepted the idea of an intracellular fermentation enzyme.The physiological chemists also fit the pattern in a special way. Physiological chemistry is generally regarded as the source of biochemistry; indeed, many early biochemists were trained in physiological chemistry, and imbibed there a progressive interest in enzymes and metabolism. It is not surprising, therefore, that on the whole Neumeister, Madfadyen, Wroblewski, and Loew accepted cell-free fermentation. But what is surprising, and significant, is the diversity of opinion in this group, from Abeles' living protoplasm to Wroblewski's organized array of active proteins. The feelings of the physiological chemists were mixed, and there was enough of the old protoplasm view in Macfadyen's and even Wroblewski's views to allow Buchner to see them as attacks on zymase. The ideas of physiological chemistry were also changing; the idea of protoplasm was already adjusting to the new interest in enzymes in the early 1890's. But in contrast to immunochemistry, the change in physiological chemistry was gradual, uneven, undramatic, and relatively invisible. For the new biochemistry, the tradition of physiological chemistry was the source of traditional conservatism as well as of new ideas of enzymes.In general, then, I claim that it was not experimental facts that determined attitudes toward zymase so much as previous commitments, experience, and expectations. Initially, at least, zymase was less a determinant of opinion than a touchstone of pre-existing opinion. Like a prism, it revealed the spectrum of existing attitudes toward vital phenomena.Also relevant here is the fact that the experimental evidence was entirely ambiguous; the interpretation of Buchner's experiments with antiseptics or dried yeast depended entirely on how far one was willing to stretch the scope of the terms “protoplasm” and “enzyme”. Likewise, how important one judged the instability of zymase to be, or the low level of in vitro activity, depended largely on one's point of view. There was no crucial experiment, no certain proof. Logically zymase could be regarded as protoplasm. A. Fischer did so in 1900;111 Macfadyen was still wavering in 1907;112 and Beijerinck was holding out as late as 1916.113 There were undoubtedly others. Besides the special case of Reynolds Green and the technologists, there are no recorded cases of conversion.But if there was no evidence to convert a dedicated protoplasmist, there was plenty to encourage a dedicated belief in the enzyme theory, and that, I believe, is precisely what happened. The arguments of Buchner et al in support of zymase had the greatest effect not on the protoplasmists but on those who were already predisposed toward the biochemical view. The zymase debate enabled the emerging group of biochemists to recognizethemselves as a group with a community of out-look and objectives; it brought the issue of protoplasm vs. enzyme into the open and gave it a specific and concrete issue on which to turn. The debate sharpened the biochemists' awareness that their point of view was becoming the new mainstream of biochemical thought.All this of course had an important secondary effect on those who opposed the new view, or who were not immediately concerned with it. After the zymase debate, it would have been almost impossible to ignore the new ideas; the dramatic and wide publicity the debate enjoyed would have made it difficult not to take sides. Buchner's successful defense of zymase itself became an important influence on opinion; the new movement had to be looked at with respect. But the primary effect of the debate, I assert, was on those who were already inclined to the new view. The outcome was not a mass conversion of individuals, nor the ejection of one idea by another. The sides probably did not change much; the real change was in the way each side regarded itself and its place in history. The zymase debate may perhaps best be regarded as a process of selection. Buchner's party became aware of itself as the new progressive point of view, while those holding the traditional view could no longer expound it publicly without appearing obstinate or old-fashioned. Thus the way was clear for the gradually wider establishment of the new ideas, especially among the new generation of biochemists. In this specific sense, the acceptance of zymase was a social phenomenon.This way of looking at the zymase debate also illuminates its coincidence with the emergence of biochemistry as a profession. The new professional trappings and organizations were the social manifestation of the new self-awareness gained from the zymase controversy. One of the most important effects on those disposed toward the new view was the awareness of an intellectual community and of the need to give that community social forms. The almost mythical importance of Buchner's “victory” over the old protoplasm theory that later became current is readily understandable. It was a useful ideology for a group anxious to assert the novelty of their approach, a novelty which they in fact felt quite keenly.But if the primary effect of the zymase controversy was on those predisposed to accept zymase, then obviously the success of zymase depended on the fact that change had already begun to occur. Indeed, one of the most striking, and again unexpected, results of this study is the extent to which the importance of enzymes was already recognized in the early 1890's. The new immunology clearly pointed the way. Macfadyen and Hans Buchner were looking for active proteins inside the cell in 1893. Reynolds Green, Wroblewski, and Pfeffer had all anticipated the discovery of a fermentation enzyme. Other discoveries in enzymology in the 1890's pointed the same way.114 Moreover, it is clear from this study that the old protoplams theory was adapting to the new discoveries concerning the importance of enzymes. The sidechains of the old protoplasm molecule were simply reinterpreted as enzymes, as in Wroblewski's theory, for example, or in Paul Ehrlich's extremely influential “sidechain theory” of antibody formation (1897). Despite the later views of Hopkins et al., the old protoplasm and the new enzyme theories were not irreconcilable; a continuity of development had already begun when zymase came so dramatically on the scene. Buchner himself observed that the difference between the two views had become largely verbal; in retrospect we might say, not verbal, but social and historical. The gap between the continuous change in ideas and the contemporary feeling of sharply discontnuous change is a measure of the elusive but real social and historical implications of the zymase debate, of the demise of an old establishment, and the emergence of a new.In retrospect, then, it is clear that a trend was already under way in various quarters when zymase appeared. But it was still a collection of isolated and dispersed events. The zymase controversy made the trend visible and gave it a dramatic unity. The debate influenced those who had already begun to change. It was so effective because things had begun to change and because it coincided with the direction of that trend. (shrink)

Many in science are disposed not to take biosemiotics seriously, dismissing it as too anthropomorphic. Furthermore, biosemiotic apologetics are cast in top-down fashion, thereby adding to widespread skepticism. An effective response might be to approach biosemiotics from the bottom up, but the foundational assumptions that support Enlightenment science make that avenue impossible. Considerations from ecosystem studies reveal, however, that those conventional assumptions, although once possessing great utilitarian value, have come to impede deeper understanding of living systems because they implicitly depict (...) the evolution of the universe backward. Ecological dynamics suggests instead a smaller set of countervailing postulates that allows evolution to play forward and sets the stage for tripartite causalities, signs, and interpreters—the key elements of biosemiosis—to emerge naturally out of the interaction of chance with configurations of autocatalytic processes. Biosemiosis thereby appears as a fully legitimate outgrowth of the new metaphysic and shows promise for becoming the supervenient focus of a deeper perspective on the phenomenon of life. (shrink)

In this thesis, I both analyze the phenomenology of vision from a geometrical point of view, and also develop certain connections between that geometrical analysis and the mind body problem. In order to motivate the need for such an analysis, I first show, by means of a refutation of direct realism, that visual space is never identical with any of the physical objects being indirectly "seen" by constituting color arrangements in it. It thus follows that the geometry of visual space (...) may be quite different from the Euclidean geometry of physical space, and I proceed to analyze that geometry. ;I argue that topologically, visual space is two dimensional, inasmuch as regions of it are capable of being bounded by a line, such as the borders around the various objects constituted in it. An apparent paradox arises here though, inasmuch as we posess phenomenal depth perception, which is particularly striking during binocular vision, and thus the question arises as to how the binocular depth cue of retinal disparity is registered phenomenally in a two dimensional space. I resolve this apparent paradox by arguing that the internal metric struture of this space can be apprehended phenomenally, and can serve as such a phenomenal depth cue. It is shown that holistically, this metric structure is elliptical, since for example marginal distortions in wide-angle photography are not present in visual space, and it is also noted that there is a tendency towards size constancy in visual perception. It is shown from these geometrical considerations that visual space posseses a variable curvature, with that curvature being determined by the physical depths of objects constituted in the space. ;Finally, I investigate what bearing the preceding geometrical conclusions have on the question of how events in visual space may be causally determined by neural events in the brain. The classical isomorphic theory of Gestalt psychology is then reinterpreted in light of my analysis of the geometry of visual space. (shrink)

Mechanical reductionism, which deals entirely with homogeneous variables, will constrain and enable the activities of richly heterogeneous living systems, but it cannot determine their outcomes. Such indeterminism owes to problems with dimensionality, dynamical logic, intractability, and insufficiency. The order in any living structure arises via an historical series of contingencies that were selected endogenously by stable autocatalytic processes in tandem with, and usually in opposition to, conventional external influences (natural selection). The development of living communities thereby resembles a Heraclitean dialectic (...) between processes that build up and those that tear down. Investigating this unconventional dynamic requires metaphysical assumptions that are complementary to those that have guided science over the past three centuries. The new dynamics can be represented in terms of weighted networks of interacting processes, which facilitate the statement of testable hypotheses. Network analysis thereby implements and tests ideas that heretofore could only be addressed as verbal propositions. (shrink)
