As historian Henning Schmidgen notes, the scientific study of the nervous system would have been “unthinkable” without the industrialization of communication in the 1830s. Historians have investigated extensively the way nerve physiologists have borrowed concepts and tools from the field of communications, particularly regarding the nineteenth-century work of figures like Helmholtz and in the American Cold War Era. The following focuses specifically on the interwar research of the Cambridge physiologist Edgar Douglas Adrian, and on the technology that led to his (...) Nobel-Prize-winning research, the thermionic vacuum tube. Many countries used the vacuum tube during the war for the purpose of amplifying and intercepting coded messages. These events provided a context for Adrian's evolving understanding of the nerve fiber in the 1920s. In particular, they provide the background for Adrian's transition around 1926 to describing the nerve impulse in terms of “information,” “messages,” “signals,” or even “codes,” and for translating the basic principles of the nerve, such as the all-or-none principle and adaptation, into such an “informational” context. The following also places Adrian's research in the broader context of the changing relationship between science and technology, and between physics and physiology, in the first few decades of the twentieth century.

ArgumentThe Minnesota Multiphasic Personality Inventory (MMPI) was developed at the University of Minnesota, Minneapolis, in the 1930s and 1940s. It became a highly successful and highly controversial psychometric tool. In professional terms, psychometric tools such as the MMPI transformed psychology and psychiatry. Psychometric instruments thus readily fit into the developmental history of psychology, psychiatry, and neurology; they were a significant part of the narrative of those fields’ advances in understanding, intervening, and treating people with mental illnesses. At the same time, (...) the advent of such tools also fits into a history of those disciplines that records the rise of obsessional observational and evaluative techniques and technologies in order to facilitate patterns of social control that became typical during the Progressive Era in the United States and after. It was those patterns that also nurtured the resistance to psychometrics that emerged during the Vietnam War and after. (shrink)

What role does context play in the mind and brain sciences? This introductory article, “Of Means and Ends,” explores that question through its focus on the ways scientists and physicians engaged with and constructed technology in the mind and brain sciences in the twentieth century. This topical issue addresses how scientists, physicians, and psychologists came to see the ends of technology as important in-and-of themselves. In so doing, the authors of these essays offer an interpretation of historian Paul Forman's revisionist (...) and highly contextualist chronology of the twentieth century, which presents the comparatively recent tendency to aggrandize the ends of technology as evidence of a major, epochal transformation in the epistemic culture of twentieth-century American science. This collection of papers suggests that it was in the vanguard of such fields as psychology, psychiatry, and neurophysiology in North America and Europe that the ends and applications of technology became important in-and-of themselves.

ArgumentIn the 1970s a public controversy erupted over the proposed use of brain operations to curtail violent behavior. Civil libertarians, civil rights and community activists, leaders of the anti-psychiatry movement, and some U.S. Congressmen charged psychosurgeons and the National Institute of Mental Health, with furthering a political project: the suppression of dissent. Several government-sponsored investigations into psychosurgery rebutted this charge and led to an official qualified endorsement of the practice while calling attention to the need for more “scientific” understanding and (...) better ethical safeguards. This paper argues that the psychosurgery debate of the 1970s was more than a power struggle between members of the public and the psychiatric establishment. The debate represented a clash between a postmodern skepticism about science and renewed focus on ultimate ends, on the one hand, and a modern faith in standards and procedures, a preoccupation with means, on the other. These diverging commitments made the dispute ultimately irresolvable. (shrink)

Preliminary remark:The following conversation began as a series of written email exchanges. Due to technical reasons, this exchange had to be interrupted at some point. Rather than rewriting the text that had obtained from scratch, I continued the conversation, turning the real “other” of the dialogue into an imagined one. Heartfelt thanks to Oren Harman, the guest editor of this topical issue, for continuing support and for having taken the risk of designing this unusual topical issue ofScience in Contextwith me.

The sequence of nucleotide bases occurring in an organism’s DNA is often regarded as a codescript for its construction. However, information in a DNA sequence can only be regarded as a codescript relative to an operational biochemical machine, which the information constrains in such a way as to direct the process of construction. In reality, any biochemical machine for which a DNA codescript is efficacious is itself produced through the mechanical interpretation of an identical or very similar codescript. In these (...) terms the origin of life can be described as a bootstrap process involving the simultaneous accumulation of genetic information and the generation of a machine that interprets it as instructions for its own construction. This problem is discussed within the theoretical frameworks of thermodynamics, informatics and self-reproducing automata, paying special attention to the physico-chemical origin of genetic coding and the conditions, both thermodynamic and informatic, that a system must fulfil in order for it to sustain semiosis. The origin of life is equated with biosemiosis. (shrink)

The essays in this topical issue illustrate the changing cultural form and function of the biopsyche disciplines – disciplines that are both sciences and technologies of selfhood. To varying degrees, each essay actively engages Paul Forman's thesis on modern and postmodern cultural valuations of science and technology. Forman invites those who read his work to view the cultural space framing science and technology in new ways.
