What does the discussion of polygamous and monogamous cultures show, according to Herskovits? What is he trying to get his readers to think regarding polygamy? (That is, what does he want you to think about polygamy, after reading his discussion of it?) Given this, is he being consistent with his own cultural relativism? What should we say about the theory of cultural relativism as a whole? Is it supposed to be objectively true? Does Herskovits think so? If so, is Herskovits being consistent with himself? Is cultural relativism not supposed to be objectively true? If so, what should we say about it?
