The face in humans condenses the facts of seeing, speaking and hearing. These in turn are related to the condition of frontality, a condition which migrates to all those arrangements in which objects are said to have a front, and even a façade. The lecture course will examine this condition with special reference to the face, its visibility, its hiddenness, its tendency to support ideas of expression and of meaning. It considers the role of transforming the face through the cosmetic.
