Neuroscience, neurohistory, and the history of science: a tale of two brain images

This essay introduces a Focus section on "Neurohistory and History of Science" by distinguishing images of the brain as governor and as transducer: the former treat the brain as the executive control center of the body, the latter as an interface between the organism and reality at large. Most of the consternation expressed in the symposium about the advent of neurohistory derives from the brain-as-governor conception, which is rooted in a "biologistic" understanding of humanity that in recent years has become bound up in various nefarious "neoliberal" political and economic agendas. However, given the sophisticated attitude that neurohistory's leading champion, Daniel Smail, displays toward evolutionary theory's potential impact on historical practice, he is perhaps better understood as part of the brain-as-transducer tradition. This tradition, largely suppressed in current representations of neuroscience, has a strong theological provenance, ultimately concerned with our becoming attuned to the divine frequency, not least by extending the powers of the human nervous system through technology. This essay sympathetically explores the implications of this perspective for historical practice.
