of an abstract noun: log-os > log-ia (a "qualitative abstract") The Renaissance origin of the name of anthropology does not exclude the possibility that ancient authors presented anthropogical material under another name (see below). Such an identification is speculative, depending on the theorist's view of anthropology; nevertheless, speculations have been formulated by credible anthropologists, especially those that consider themselves functionalists and others in history so classified now. The science of history Marvin Harris, a historian of anthropology, begins The Rise of Anthropological Theory with the statement that anthropology is "the science of history". He is not suggesting that history be renamed to anthropology, or that there is no distinction between history and prehistory, or that anthropology excludes current social practices, as the general meaning of history, which it has in "history of anthropology", would seem to imply. He is using "history" in a special sense, as the founders of cultural anthropology used it: "the natural history of society", in the words of Herbert Spencer, or the "universal history of mankind", the 18th-century Age of Enlightenment objective. Just as natural history comprises the characteristics of organisms past and present, so cultural or social history comprises the characteristics of society past and present. It includes both documented history and prehistory, but its slant is toward institutional development rather than particular non-repeatable historical events. According to Harris, the 19th-century anthropologists were theorizing under the presumption that the development of society followed some sort of laws. He decries the loss of that view in the 20th century by the denial that any laws are discernable or that current institutions have any bearing on ancient. He coins the term ideographic for them. The 19th-century views, on the other hand, are nomothetic; that is, they provide laws. He intends "to reassert the methodological priority of the search for the laws of history in the science of man". He is looking for "a general theory of history". His perception of the laws: "I believe that the analogue of the Darwinian strategy in the realm of sociocultural phenomena is the principle of techno-environmental and techno-economic determinism", he calls cultural materialism, which he also details in Cultural Materialism: The Struggle for a Science of Culture. Elsewhere he refers to "my theories of historical determinism", defining the latter: "By a deterministic relationship among cultural phenomena, I mean merely that similar variables under similar conditions tend to give rise to similar
