Fe?lix Guattari was a French political militant, practicing psychoanalyst and international public intellectual. He is best known for his work with the philosopher Gilles Deleuze on the two-volume Capitalism and Schizophrenia, one of the most influential works of post-structuralism. From the mid-1950s onward, Guattari exerted a profound yet often behind-the-scenes influence on institutional psychotherapy, psychoanalysis, radical politics and philosophy. Guattari's Diagrammtic Thought examines the writings that Guattari authored on his own, both before and during his collaboration with Deleuze, providing a startlingly fresh perspective on intellectual and political trends in France and beyond during the second half of the twentieth century. Janell Watson acknowledges the historical and biographical aspect of Guattari's writing and explores the relevance of his theoretical ideas to topics as diverse as the May 1968 student movement, Lacanian psychoanalysis, neo-liberalism, ethnic identity, microbiology, quantum mechanics, chaos theory, ecology, the mass media, and the subjective dimensions of information technology. The book demonstrates that Guattari's unique thought process yields a markedly Guattarian version of many seemingly familiar Deleuzean notions
