TIME AND ARCHAEOLOGYDiscussions of time in the archaeological literature have generally been domin ated by problems of time measurement. Time concepts, however, have re ceived little attention until recently (3, 11-13, 20, 38, 66, 72, 75, 80, 81, 93, 94, 97 , 105, 1 14), even though they have been a longstanding source of interest to many other disciplines including philosophy, the natural and social sciences, history, and geography (1, 7, 15, 17, 18,21,33,42,43,46,48,49,52,57,87, 99, 11� 1 12). To a large extent this is traceable to the difficulties of dating. It is only with the relatively recent development and widespread application of radiometric dating methods that archaeologists have begun to free themselves from technical preoccupations and to concentrate more fully on problems of process. Above all, new dating methods have demonstrated that human cultural history extends over a time span of at least two million years. This poses in a new way the issue of how we are to make use of knowledge about the past, what questions we should ask of it, and whether, by archaeological investigation of human activities over this time span, we can learn something new about human nature not available from other sources. I use the term quaternary prehistory here to emphasize an interest, in principle, in a time span of up to two million years. The effect of time concepts on archaeological interpretation can be consi dered from two points of view. The first examines their influence on the thinking of archaeologists in their interpretation of past behavior. The second examines their influence on the thinking and behavior of prehistoric people and hence on the patterns which contribute to the archaeological record. Contrasting notions of time are more or less implicit in archaeological thinking and have resulted in misguided rivalry between alternative approaches 165 0066-4294/83/101�165$02.00Annu. Rev.
