Brains/Practices/Relativism presents the first major rethinking of social theory in light of cognitive science. Stephen P. Turner focuses especially on connectionism, which views learning as a process of adaptation to input that, in turn, leads to patterns of response distinct to each individual. This means that there is no common "server" from which people download shared frameworks that enable them to cooperate or communicate. Therefore, argues Turner, "practices"—in the sense that the term is widely used in the social sciences and humanities—is a myth, and so are the "cultures" that are central to anthropological and sociological thought.

In a series of tightly argued essays, Turner traces out the implications that discarding the notion of shared frameworks has for relativism, social constructionism, normativity, and a number of other concepts. He suggests ways in which these ideas might be reformulated more productively, in part through extended critiques of the work of scholars such as Ian Hacking, Andrew Pickering, Pierre Bourdieu, Quentin Skinner, Robert Brandom, Clifford Geertz, and Edward Shils.

The late 1960s are remembered today as the last time wholesale social upheaval shook Europe and the United States. College students during that tumultuous period—epitomized by the events of May 1968—were as permanently marked in their worldviews as their parents had been by the Depression and World War II. Sociology was at the center of these events, and it changed decisively because of them.

The Disobedient Generation collects newly written autobiographies by an international cross-section of well-known sociologists, all of them "children of the '60s." It illuminates the human experience of living through that decade as apprentice scholars and activists, encountering the issues of class, race, the Establishment, the decline of traditional religion, feminism, war, and the sexual revolution. In each case the interlinked crises of young adulthood, rapid change, and nascent professional careers shaped this generation's private and public selves. This is an intensely personal collective portrait of a generation in a time of struggle.

The concept of "practices"—whether of representation, of political or scientific traditions, or of organizational culture—is central to social theory. In this book, Stephen Turner presents the first analysis and critique of the idea of practice as it has developed in the various theoretical traditions of the social sciences and the humanities.

Understood broadly as a tacit understanding "shared" by a group, the concept of a practice has a fatal difficulty, Turner argues: there is no plausible mechanism by which a "practice" is transmitted or reproduced. The historical uses of the concept, from Durkheim to Kripke's version of Wittgenstein, provide examples of the contortions that thinkers have been forced into by this problem, and show the ultimate implausibility of the idea.

Turner's conclusion sketches a picture of what happens when we do without the notion of a shared practice, and how this bears on social theory and philosophy. It explains why social theory cannot get beyond the stage of constructing fuzzy analogies, and why the standard constructions of the contemporary philosophical problem of relativism depend upon this defective notion. This first book-length critique of practice theory is sure to stir discussion and controversy in a wide range of fields, from philosophy and science studies to sociology, anthropology, literary studies, and political and legal theory.
