“The tools of the discipline: Biochemists and molecular biologists”: A comment

This last result leads, rather naturally, to some concluding observations and a series of questions for further investigation. These case studies show that in all of the sites examined, the institutionalization of molecular biology as a “discipline” was primarily driven by the need to separate groups of practitioners with divergent but overlapping interests within the local context. Thus molecular biology was contingently separated from agricultural or medical biochemistry, virology, work on the physiology of nucleic acids, and so forth for contingent local institutional reasons. This makes it even more pressing to try to understand how molecular biology came to be delimited on a larger scale. How did it come to be a discipline with specific intellectual content (or did it?), including some problems, tools, and practices and excluding others? How did it gain authority as the forefront biological science by the mid-1960s? We need to understand the ways in which the tensions between different practices, projects, aims, understandings of the goals of molecular biology, and so on were resolved, on what scale and in what venues, so that something approximating the political character of a discipline, rather than a federation, was achieved. If these case studies provide a sound starting point, it will nevertheless prove difficult to answer the interconnected questions implicit here satisfactorily. One means of getting at such questions that should prove of considerable interest is to examine carefully the work of those who were widely cited in the papers of the late fifties through the mid-seventies by the people now considered major founders of molecular biology. By studying the contributions of those who are now omitted in the standard histories and recollections, we will gain a clearer sense of the possibilities that were open as molecular biology took shape. It is already widely recognized that the contributions of a number of biochemists have been given short shrift, but (as the example of Ernest Gale in Rheinberger's study illustrates) there are a great many more figures whose line of work were then crucial but who are now overlooked.6 To understand both what molecular biology was at the time of its early institutionalization and what is has become, it will be enormously helpful to understand at what point the definition or ideology “hardened” and the grounds for inclusion and exclusion of individuals and lines of work were reformed. Studies of this sort are appropriate in many other areas as well, of course; in general, they should different histories, political standing, and institutional bases of those disciplines in their national cultures. It is likely (but a matter for investigation!) that such differences influenced the opportunities for introducing new bench practices, if in no other way than by delimiting the niches within which certain practices could be initiated.7 And since new practices can fail to achieve their objectives, can transform the direction of work and disciplinary allegiances of their practitioners, can lead to only routine results, or can open up important new vistas, the character of the available niches from which to work can prove to have a strong influence on the direction that new work takes if and when it starts to flourish. A key aspect of this problematic (not yet adequately studied, I believe) is the problem of drawing boundaries between different kinds of work and determining where each should fit among established disciplines and/or within some new construct. To the extent that an “international” solution is ultimately achieved to such problems, it must surely be achieved in light of initially different ways of dealing with it in different countries. Underlying work of the sort we have been exploring is the thorny problem of how best to contextualize the work being studied. This, I believe, is one of the major historiographic problems that we must face in the history of science. It is by no means a new problem, of course, but a particularization of the age-old problem of the (seeming) overdetermination of historical events. If we deal with local cultures, to understand how they develop and their fate we need to understand their location within larger cultures. But it is utterly unclear how to draw appropriate boundaries on the relevant larger culture(s). As even this brief discussion has shown, institutional cultures, the cultures of sponsoring agencies, “the” culture of science (or of biological science, physical science, etc., as appropriate), and national cultures all can provide relevant contexts, all can occasionally determine the fate of work undertaken in a particular local context. The potentially intractable problem of delimiting the boundaries of investigation looms large here, but it is one that must be faced explicity if we are to profit fully from the enormously stimulating investigations of local cultures exemplified in the four papers published in this symposium. My own view is that we have no abstract standard available for determining which boundaries are appropriate to a given study, and, indeed, that no single contextualization is adequate to the examination of any given case, but that, nonetheless, we can (at least sometimes) distinguish useful and explanatory delimitations of the larger context from others that prove to be misleading. Against this background, I hope that the four papers published in this special issue will stimulate the readers of the JHB to carry out similar studies—that is, studies that seek to characterize and contextualize local experimental cultures —over a wide range of cases. I also hope that some of those who take up this challenge will deal with the larger questions raised by the need to find a way of balancing different, sometimes competing, contextualizations of such studies. The fact that any given case requires multiple contextualizations, resulting in multifaceted representations no one of which is alone adequate, will surely land us in fascinating, hopefully fruitful and productive, controversies.
