Detachment, Involvement, and Rationality: are we Essentially Rational Animals? Philosophers have long thought that what differentiates humans from mere animals is that humans are essentially rational. The rational nature of human beings lies in their ability to detach themselves from ongoing involvement and to ask for as well as give reasons for activity. According to the philosophical tradition, human action and perception generally should be understood in light of this ability. This essay examines a contemporary version of this conviction, one (...) promulgated by John McDowell. McDowell follows the tradition in suggesting that people are always able to step back and to ask as well as answer why questions about what they are doing, i.e., they always have reasons for their actions. This essay shows that people have no reasons for many of the things they do. They often, instead, simply respond to shifting situational fields of attraction and repulsion. These attractions and repulsions cannot be captured in propositional form—any attempt to describe, or even just name, them turns them into objects and robs them of their motivational force. The demands of the situation are not available as reasons, but exist only as embodied in actions. McDowell, consequently, errs in claiming that conceptual capacities are inextricably implicated in human activity. Nor is the detached, rational way of being any more essential to human life than is involved coping. (shrink)

A revised translation of Heidegger's most important work.

Heidegger's Pragmatism deals with the relation between Martin Heidegger's early analysis of intentionality and his eventual rejection of metaphysics. Arguing for the essentially pragmatic nature of the early Heidegger's discussion of understanding, Mark Okrent shows that Heidegger's subsequent critique of metaphysics follows directly from his long-held pragmatic understanding of intentionality. Heidegger's Pragmatism is written with a clarity that makes it accessible to analytic and continental philosophers alike. Its boldly original conclusions will engage Heidegger scholars, literary theorists, intellectual historians, and a (...) wide range of philosophers. (shrink)

This lucidly written book examines the social and political significance of the natural sciences through a detailed and original account of science as an interpretive social practice.

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)

A revisionist movement in Anglo-Saxon philosophy of science seeking to modulate the positivistic stress on formalized systems and to consider science as ongoing research in finite historical context strikes resonances with hermeneutical phenomenology , whose ontology likewise shifts the locus of truth from verification to discovery. Fusion of the two traditions is utilized to illuminate hitherto relatively unexplored facets of the logic and psychology of scientific discovery, as well as its ontology, here developed from the intentional intertwining of man and (...) nature and finding its locus in the linguistic historicity of fundamental scientific concepts.

Against Davidsonian (or deflationary) realism, it is argued that it is coherent to believe that science can in principle give us access to the functional components of the universe as they are in themselves in distinction from how they appear to us on the basis of our quotidian concerns or sensory capacities. The first section presents the deflationary realist's argument against independence. The second section then shows that, although Heidegger pioneered the deflationary realist account of the everyday, he sought to (...) establish a robust realist account of science. Next, the third section develops two different sides of Heidegger's thinking. Resources developed by Thomas Kuhn are drawn on to work out Heidegger's account of plural worlds. This argument shows that it makes sense to talk about things-in-themselves independent of our practices, but falls short of the robust realist claim that we can have access to things as they are in themselves independent of our practices. So, secondly, Saul Kripke's account of rigid designation is drawn on to work out Heidegger's account of formal designation. On the basis of a Heideggerian elaboration of rigid designation, it is argued that we do indeed have practices for achieving access to things independent of all our practices. But this second argument leaves us unable to reject metaphysical nominalism. So, thirdly, it is proposed that the currently most persuasive philosophical argument for nominalism depends on a logico-mathematical space of possibilities. But the proto-theoretical space opened by the pre-scientific access practices has features that provide reasons for believing that the independent stuff to which we have access has a determinate structure and specific causal powers.

The author proposes the thesis that all perception, including observation in natural science, is hermeneutical as well as causal; that is, the perceiver (or observer) learns to 'read' instrumental or other perceptual stimuli as one learns to read a text. This hermeneutical aspect at the heart of natural science is located where it might be least expected, within acts of scientific observation. In relation to the history of science, the question is addressed to what extent the hermeneutical component within scientific (...) observation opens natural science to the charge of reflecting merely cultural values, and of providing merely a culturally acceptable reading of the "Book of Nature", rather than, as the author states, one stating universal antecedent conditions of possibility of cultural activity itself.

This paper describes Heidegger as a robust scientific realist, explains why his view has received such conflicting treatment, and concludes that the special significance of his position lies in his insistence upon linking the discussion of science to the question of its relation with technology. It shows that Heidegger, rather than accepting the usual forced option between realism and antirealism, advocates a realism in which he embeds the antirealist thesis that the idea of reality independent of human understanding is unintelligible. (...) This reading is defended against Rorty's antirealist interpretation, as well as Dreyfus' depiction of him as a deflationary realist, and his assessment of background realism is contrasted with Fine's. Further, the robustness of Heidegger's realism is laid out across several texts from 1912 to 1976, in order to show that he is neither an instrumental realist nor an internal realist. Finally, the point is made that the development of his view concerning realism gives rise to a critique of objectivity that is now being similarly advocated by numerous thinkers from a variety of disciplines, and that this critique is inevitably ethical and political.

The paper provides an overview of the hermeneutic and phenomenological context from which the idea of a “constitutional analysis” of science originated. It analyzes why the approach to “hermeneutic fore-structure of scientific research” requires to transcend the distinction between the context of justification and the context of discovery. By incorporating this approach into an integral “postmetaphysical philosophy of science”, I argue that one can avoid the radical empiricism of recent science studies, while also preventing the analysis of science's discursive practices (...) from collapsing into the frames of radical anti-epistemological critique mandated by some hermeneutic philosophers.

The discovery that some B vitamins are constituents of respiratory coenzymes led to the development of an interfield theory of the kind discussed by Darden and Maull. In this paper it is shown that the development of a useful interfield connection was made possible by two reconceptualizations: a reconceptualization that united two then-distinct fields giving rise to the concept of vitamins as dietary substances; and another reconceptualization that united two approaches to respiratory metabolism producing the idea that coenzymes are transport (...) vehicles.

Developing models of biological mechanisms, such as those involved in respiration in cells, often requires collaborative effort drawing upon techniques developed and information generated in different disciplines. Biochemists in the early decades of the 20th century uncovered all but the most elusive chemical operations involved in cellular respiration, but were unable to align the reaction pathways with particular structures in the cell. During the period 1940-1965 cell biology was emerging as a new discipline and made distinctive contributions to understanding the (...) role of the mitochondrion and its component parts in cellular respiration. In particular, by developing techniques for localizing enzymes or enzyme systems in specific cellular components, cell biologists provided crucial information about the organized structures in which the biochemical reactions occurred. Although the idea that biochemical operations are intimately related to and depend on cell structures was at odds with the then-dominant emphasis on systems of soluble enzymes in biochemistry, a reconceptualization of energetic processes in the 1960s and 1970s made it clear why cell structure was critical to the biochemical account. This paper examines how numerous excursions between biochemistry and cell biology contributed a new understanding of the mechanism of cellular respiration. (shrink)

In this powerful work of conceptual and analytical originality, the author argues for the primacy of the material arrangements of the laboratory in the dynamics of modern molecular biology. In a post-Kuhnian move away from the hegemony of theory, he develops a new epistemology of experimentation in which research is treated as a process for producing epistemic things. A central concern of the book is the basic question of how novelty is generated in the empirical sciences. In addressing this question, (...) the author brings French poststructuralist thinking—notably Jacques Derrida’s concepts of “différance” and “historiality”—to bear on the construction of epistemic things. Historiographical perspective shifts from the actors’ minds to their objects of manipulation. These epistemological and historical issues are illuminated in a detailed case study of a particular laboratory, that of the oncologist and biochemist Paul C. Zamecnik and his colleagues, located in a specific setting—the Collis P. Huntington Memorial Hospital of Harvard University at the Massachusetts General Hospital of Boston. The author traces how, between 1945 and 1965, this group developed an experimental system for synthesizing proteins in the test tube that put Zamecnik’s research team at the forefront of those who led biochemistry into the era of molecular biology.

_ _In __The Tenets of Cognitive Existentialism__, Dimitri Ginev draws on devel-opments in hermeneutic phenomenology and other programs in hermeneutic philosophy to inform an interpretative approach to scientific practices. At stake is the question of whether it is possible to integrate forms of reflection upon the ontological difference in the cognitive structure of scientific research. A positive answer would have implied a proof that “science is able to think.” This book is an extended version of such a proof. Against those (...) who claim that modern science is doomed to be exclusively committed to the nexus of objectivism and instrumental rationality, the interpretative theory of scientific practices reveals science’s potentiality of hermeneutic self-reflection. Scientific research that takes into consideration the ontological difference has resources to enter into a dialogue with Nature. Ginev offers a critique of postmodern tendencies in the philosophy of science, and sets out arguments for a feminist hermeneutics of scientific research. (shrink)

The concept of fore-structure is central to Heidegger’s idea of interpretation. Gadamer later incorporated this concept into his own theory of philosophical hermeneutics. But there are indeed certain signifcant differences between their accounts of the fore-structure, and these differences are o ften neglected by scholars. This essay will first present Heidegger’s concept of fore-structure, and then we will demonstrate the differences between Heidegger and Gadamer. At last, we will draw out some implications of Heidegger’s concept of fore-structure to textual Interpretation.
