Throughout his career, the influential new media theorist Vilem Flusser kept the idea of gesture in mind: that people express their being in the world through a sweeping range of movements. He reconsiders familiar actions-from speaking and painting to smoking and telephoning-in terms of particular movement, opening a surprising new perspective on the ways we share and preserve meaning. A gesture may or may not be linked to specialized apparatus, though its form crucially affects the person who makes it.

These essays, published here as a collection in English for the first time, were written over roughly a half century and reflect both an eclectic array of interests and a durable commitment to phenomenological thought. Defining gesture as a movement of the body or of a tool attached to the body for which there is no satisfactory causal explanation, Flusser moves around the topic from diverse points of view, angles, and distances: at times he zooms in on a modest, ordinary movement such as taking a photograph, shaving, or listening to music; at others, he pulls back to look at something as vast and varied as human making, embracing everything from the fashioning of simple tools to mass manufacturing. But whatever the gesture, Flusser analyzes it as the expression of a particular form of consciousness, that is, as a particular relationship between the world and the one who gestures.
