A historical and critical analysis of the concept of the gene that attempts to provide new perspectives and metaphors for the transformation of biology and its philosophy.
The existence claim of a "genetic program" encoded in the DNA molecule which controls biological processes such as development has been examined. Sources of belief in such an entity are found in the rhetoric of Mendelian genetics, in the informationist speculations of Schrodinger and Delbruck, and in the instrumental efficacy found in the use of certain viral, and molecular genetic techniques. In examining specific research models, it is found that attempts at tracking the source of biological control always leads back (...) to the complex state of a cell as a whole, the organizational structure of which is not itself encoded in the DNA. It is argued that the "genetic program" is not an existing biological entity and its philosophical and heuristic status is challenged. (shrink)
There are many in the social sciences and social philosophy who would aspire to overcome the ‘nature/culture binary’, including some who, with at least an implicit nod toward a putatively ‘anti-essentialist’ process ontology, have set out with an orientation toward a paradigm of ‘biosocial becoming’. Such contemporary work, however, in areas such as social and cultural anthropology and sciences studies has often failed to clarify, let alone justify, the warrants of their most basic assumptions and assertions. In what follows, adumbrations (...) will be offered for a comprehensive metaphysics of ‘biosocial becoming’ that can stand accountable both to empirical/descriptive and to normative claims. (shrink)
From a subjective point of view, we take the existence of integrated entities, i.e., ourselves as the most unproblematic given, and blithely project such integrity onto untold many “entities” far and wide. However, from a naturalistic perspective, accounting for anything more integral than the attachments and attractions that are explicable in terms of the four fundamental forces of physics has been anything but straightforward. If we take it that the universe begins as an integral unity and explodes into progressive stages (...) of internal detachment, then we can also fathom the idea that eddies of relative detachment becoming increasingly integral. Helmuth Plessner made a powerful case for the onset of “positionality” constituting one of the major transitions in nature. Surely, the emergence of “entities” that position themselves in relation to their surround marks a decisive transition in relative levels of detachment and some would say “autonomy.” It would follow, with no less force, that where and when entities can be seen to be normatively integrated, and indeed to be the agents of their own normativity, that another threshold of detachment has been crossed. The paper introduces and explores the idea that normativity, embedded in a wide-ranging theory of natural detachment, can be considered an emergent force of nature that is requisite to accounting for levels of integration beyond that which is explicable in terms of the four fundamental forces of physics. Following this line of enquiry, we argue that the first expression of a fully, normatively-integrated life-form is neither a spoken language user nor for that matter an individual but rather the neoteny-based, Homo erectus Group. In so doing we claim to have made an inroad into embedding the force of normativity into a wide-ranging naturalist framework, to have provided philosophical anthropology with a new point of departure, and at least playfully, to have given some naturalistic grist to Hegel’s proclamation that spirit is the truth of nature.

Radically new or unexpected findings in a science demand an openness to new concepts and styles of explanation. The time is more than ripe for asking ourselves what we have learned from the research program of comparative genomics. Where not long ago the human genome was expected to reveal a close association of complexity with the quantitative expansion of the roster of unique genes, more recent findings, especially in relation to comparisons between human and chimp, have raised the bracing possibility (...) that when it comes to complexity, it may be that `less is more'. But `less is more' is not the only observation or inference that follows from the data. The idea of `progressive detachment' will be introduced and set forth as the most perspicuous conceptual resource for unifying and interpreting the overall findings from comparative genomics to date.

The categories and contours of a normative social theory are prefigured by its ‘anthropological’ presuppositions. The discourse/communicative-theoretic basis of Habermasian theory was prefigured by a strong anthropological demarcation between an instrumentally structured realm of science, technology and labor versus a normatively structured realm of social interaction. An alternative anthropology, bolstered by current work in the empirical sciences, finds fundamental normative needs for orientation and ‘compensation’ also to be embedded in embodied material practices. An emerging anthropologically informed concept of skill that (...) goes beyond old manual versus intellectual dichotomies and brings forth internal criteria of autonomy and authenticity can serve as a new bridge between categories of social justice, such as Sen and Nussbaum’s basic human ‘capabilities’, and new cutting-edge work in the empirical human sciences and thereby provide Critical Theory with a renewed point of departure that is both normatively and descriptively rich, for advancing its dialectical, historical mission.

Much of the philosophical attention directed to Kant’s intervention into biology has been directed toward Kant’s idea of a transcendental limit upon what can be understood constitutively. Kant’s own wider philosophical practice, however, was principally oriented toward solving problems and the scientific benefits of his methodology of teleology have been largely underappreciated, at least in the English language literature. This paper suggests that all basic biology has had, and continues to have, a need for some form of heuristic “bracketing” and (...) that a renewal of some form of, albeit flexible, teleological methodological bracketing can better complement the productive assimilation into developmental biology of continuing advances in our understanding of the mesoscale physics and chemistry of soft, excitable condensed matter, than what has been the prevailing and de facto use of a form of bracketing shaped by the neoDarwinian Modern Synthesis. Further we offer a concept of biogeneric processes and a framework of physico-genetic “dynamical patterning modules”, that can begin to account for the appearance of new Kantian “stocks of Keime und Anlagen”, capable of potentiating some range of possible organismal forms, and provide grounds for moving up the teleological “goalposts”, i.e., expanding the range of what can be accounted for on a constitutive basis.

If the question ``What is a gene?'' proves to be worth asking it must be able to elicit an answer which both recognizes and address the reasons why the concept of the gene ever seemed to be something worth getting excited about in the first place as well analyzing and evaluating the latest develops in the molecular biology of DNA. Each of the preceding papers fails to do one of these and sufferrs the consequences. Where Rolston responds to the apparent (...) failure of molecular biology to make good on the desideratum of the classical gene by veering off into fanciful talk about ``cybernetic genes,'' Griffiths and Stotz lose themselves in the molecular fine print and forget to ask themselves why ``genes'' should be of any special interst anyway.

The concept of the gene has been the central organizing theme of 20th century biology. Biology has become increasingly influential both for philosophers seeking a naturalized basis for epistemology, ethics, and the understanding of the mind, as well as for the human sciences generally. The central task of this work is to get the story right about genes and in so doing provide a critical and enabling resourse for use in the further pursuit of human self-understanding. ;The work begins with (...) a wide-ranging historical reconstruction and conceptual analysis of the meaning of "the gene" that results in defining and distinguishing two different "genes". Each of these can be seen as an heir to one of the two major historical trends in explaining the source of biological order---preformationism and epigenesis. The preformationist gene predicts phenotypes but only on an instrumental basis where immediate medical and/or economic benefits can be had. The gene of epigenesis , by contrast, is a developmental resource that provides templates for RNA and protein synthesis but has in itself no determinate relationship to organismal phenotypes. The seemingly prevalent idea that genes constitute information for traits is based, I argue, upon an unwarranted conflation of these two senses which is in effect held together by rhetorical glue. Beyond this historical, conceptual, and rhetorical inquiry the bulk of the dissertation then concerns itself with an empirically up-to-date analysis of the cell and molecular basis of biological order and of the pathological loss of same. In each of these chapters I structure my analysis with the idea in mind that the "conflated" view can be held empirically accountable. Major touchpoints in this work include the ideas of I. Kant, J. Blumenbach, K. E. von Baer, J. Muller, R. Virchow, W. Johannsen, R. Falk, J. Sapp, E. Schrodinger, M. Delbruick, G. Gamow, R. Doyle, L. Kay, S. Kauffman, E. Jablonka, J. Rothman, K. Yamamoto, P. Rous, H. Temin, J. M. Bishop, H. Harris, E. Stanbridge, D. L. Smithers, B. Vogelstein, E. Farber and H. Rubin. (shrink)
In her recent book Lindley Darden has endeavored to reclaim for philosophy an active role in the elaboration of good science. She has done this, not by holding up some set of rational standards derived from outside of scientific practice, but rather by delving into the history of science and coming out with a set of scientific strategies. Unconcerned about whether any particular strategy wasin fact employed in a given historical case her project depends upon two claims, first that these (...) strategiescould have been successfully deployed in the particular cases from which they were construed, and second and more importantly, that these strategies can be generalized beyond any particular context and be put to future use. It will be argued that Darden''s conception of the possible context independence of scientific strategies is based upon an overly cognitivist misconstrual. An alternative account of the relationship of context dependent and context independent aspects of scientific theory formation will be offered as well as its implications for philosophy. (shrink)
