The nature of time is one of the continuing mysteries of human life. This is of particular relevance to archaeology, with its unique focus on the social development of the human species from its origins to the present. This book probes the way in which the rhythms of social life derive from our involvement in the world, particularly as those rhythms unfold over many thousands of years. The author argues that time is created through the social use of material things such as landscapes, settlements and monuments, and illustrates this with case studies drawn from Europe and the Pacific. The aim of the book is to provide a theory of social change and social being as the basis for understanding social formations over long periods of time. In developing this theory the author surveys ideas on human action and time as these have evolved over the last two centuries. Although the theory is designed and presented to be of practical use in interpreting archaeological data - exemplified here in case studies - the broad scope of the book will make it of interest to all those concerned with the interactions between people and the material world.
