It is said the market has moods and desires. It is said that we must listen to it and must anticipate how it will respond to our actions. What is the significance of these peculiar forms of speech? This book investigates the conceptual underpinnings of the idea that the market has intentions, consciousness and speech, and identifies the social and political consequences of this attribution to the market of capacities generally thought to be uniquely human. At once a work of philosophy, a cultural and social archaeology and a diagnosis of one of the central ideologies of our times, this book cuts to the heart of the linguistic forms through which our collective futures are decided.
