First Published in 1984. This book was born out of a disagreement among friends. Paul Rabinow, attending a seminar given in 1979 by Hubert Dreyfus and John Searle which concerned, among other things, Michel Foucault, objected to the characterization of Foucault as a typical structuralist. This challenge stirred a discussion that led to the proposal of a joint article which soon became a medium-length book.
