Introduction
Archeology is perhaps best thought of as the study of past ways of life. To pursue this study, archeologists focus on the relationship between the material objects made by past peoples on the one hand, and the makers' behavior on the other. Sometimes written records help; often no such records exist. In previous centuries
archeologists were content simply to find objects. Today, armed with
computers, laboratory analysis, theories about society and culture,
and a wide range of questions about human behavior, they may try to
reach into the minds of those that made and used the artifacts.
Thus their analysis acts as a bridge between the two sets of things:
one an invisible realm that includes human ways of survival, religious
beliefs, family structure, and social organization; the other a visible,
tangible accumulation of material remains such as trash, tools, ornaments,
and buildings. The latter group provides the raw material for understanding
the former through logical reasoning. In making this all-important
link, archeologists have at least three main goals: - To begin to reconstruct the ways of life that no longer exist. For example, excavations at the huge Cahokia site in western Illinois give us intriguing glimpse of the area as it was around A.D.1200 by providing numerous clues to the nature of everyday life, the richness of ceremonial activity, and the workings of economic systems in the Mississippi Valley at that time. - To give us some understanding of why human culture has changed through time. Given the delicate and complicated interplay between environment and people-either different segments of past societies or peoples of different cultures-archeologists can often isolate the occurrence of small changes in the past, such as shifts in gathering methods, changes in art motifs, or new sets of social relationships. These, in turn, may allow investigators to track changes through time and to understand the reasons for them.
The quest for cause-and-effect explanations of human behavior over the centuries is perhaps the most important ingredient of the discipline, for it has the potential to help us understand the present. This is but one of many reasons why archeology plays such a vital part in the overall study of humanity (Stuart and McManamon 1996).
