This marks the first critical study of "The Logic of Sense," Gilles Deleuze's most important work on language and ethics and a vital source for his philosophy of the event. Deleuze's thought always promised a revolution in ethical theories and the relation between language, idea, and action. James William's critical reading conveys the potential and risks of Deleuze's response to the excitement and danger of events. His interpretation engages thoroughly with "The Logic of Sense," touching on phenomenology, an analytic philosophy of language, stoicism, literary theory, and psychoanalysis. His critique illuminates all areas of Deleuze's work in philosophy, politics, literature, linguistics, and sociology.
