When comparing a society with its past or with another society, we often employ a dichotomy such as "advanced vs. backward," "developed vs. underdeveloped," "civilized vs. uncivilized," or "complex vs. simple." Sometimes these words yield too little information, because they claim simply that one society is superior to another. Sometimes they yield too much, for terms like "advanced" shroud a galaxy of vague connotations. Hence to use such words may generate conflicts of pride and conflicts of meaning, both of which subvert intelligent discourse.
