Book excerpt: Critical Theory and Marital Quarrels: Dynamics of Passionate Speech analyzes the pneumatics of conflict through a discursive archeology of police reports, court proceedings, psychiatric cases, therapy sessions, eighteenth-century relationship advice literature, and the nineteenth-century fiction. Todor Hristov argues that in order to extract knowledge from the noise of the marital fights, preachers, moralists, physicians, alienists, sociologists discarded the words as a slag, and in consequence, they were unable to explain either the recurrence or the power of discord. This study is intended as an analysis of the discursive mechanism of contentious speech based on concepts derived from critical theory, discourse analysis, speech act theory and semiotics. The discursive mechanism of quarreling is summed up in the concept of passionate speech relevant beyond family scenes, to scenes of political or public contention. This book applies the concept to examine critically the language of contemporary couples therapy and to describe the unintended effects of the passions shared by the clients and the therapists.
