Book excerpt: Called by many France's foremost philosopher, Gilles Deleuze is one of the leading thinkers in the Western World. His acclaimed works and celebrated collaborations with Félix Guattari have established him as a seminal figure in the fields of literary criticism and philosophy. The long-awaited publication of What Is Philosophy? in English marks the culmination of Deleuze's career. Deleuze and Guattari differentiate between philosophy, science, and the arts, seeing as means of confronting chaos, and challenge the common view that philosophy is an extension of logic. The authors also discuss the similarities and distinctions between creative and philosophical writing. Fresh anecdotes from the history of philosophy illuminate the book, along with engaging discussions of composers, painters, writers, and architects. A milestone in Deleuze's collaboration with Guattari, What Is Philosophy? brings a new perspective to Deleuze's studies of cinema, painting, and music, while setting a brilliant capstone upon his work.
