Material culture
Material culture study is, therefore, the study through artifacts and other pertinent historical evidence) of belief systems--the values, ideas, attitudes, and assumptions--of a particular community or society, usually across time. As a study, it is based upon the obvious premise that the existence of a man-made object is concrete evidence of the presence of a human mind operating at the time of fabrication. The common assumption underlying material culture research is that objects made or modified by humans, consciously or unconsciously, directly or indirectly, reflect the belief patters of individuals who made, commissioned, purchased, or used them, and, by extension, the belief patterns of the larger society of which they are a part.
