"History and the study of cultures do not teach or prove that values or cultures are relative. All to the contrary, that is a philosophical premise that we now bring to our study of them. This premise is unproven and dogmatically asserted for what are largely political reasons. History and culture are interpreted in the light of it, and then are said to prove the premise. Yet the fact that there have been different opinions about good and bad in different times and places in no way proves that none is true or superior to others. To say that it does so prove is as absurd as to say that the diversity of points of view expressed in a college bull session proves there is no truth. On the face of it, the difference of opinion would seem to raise the question as to which is true or right rather than to banish it. The natural reaction is to try to resolve the difference, to examine the claims and reasons for each opinion."
