The anthropological observer selects data according to an implicit cultural framework. The “facts” never speak for themselves. You might, when travelling in Africa, describe an event you see as follows: “Bert got into his jeep and drove off.” However, an African tribesmen might describe it very differently: “White man is sucked in by iron monster and is carried away.” Contained in what you take to be a simple neutral account of the facts are all the ingredients of your tacit point of view: that people act freely; that they act intentionally; that machines are inanimate; that they can be made to move; that science differs from magic. When do these implicit presuppositions of yours become explicit? On what common ground can they ever be confronted by those of your African counterpart?
