Book excerpt: This unusually innovative book treats reflexivity, not as a philosophical conundrum, but as a practical issue that arises in the course of scholarly research and argument. In order to demonstrate the concrete and consequential nature of reflexivity, Malcolm Ashmore concentrates on an area in which reflexive "problems" are acute: the sociology of scientific knowledge. At the forefront of recent radical changes in our understanding of science, this increasingly influential mode of analysis specializes in rigorous deconstructions of the research practices and textual products of the scientific enterprise. Through a series of detailed examinations of the practices and products of the sociology of scientific knowledge, Ashmore turns its own claims and findings back onto itself and opens up a whole new era of exploration beyond the common fear of reflexive self-destruction.
