 Another objection, more directly pertinent to DMR, is that anthropologists have tacitly and mistakenly assumed that cultures are rather discrete, homogenous, and static entities—rather like the shapes in a Piet Mondrian painting or a checkerboard. In fact, according to this contention, cultures typically are rather heterogeneous and complex internally, with many dissenting voices. Moreover, they often interact and sometimes influence one another, and they may change over time. From this perspective, the world of cultures is closer to an animated Jackson Pollock painting than to the unambiguous configuration suggested by the first image. If these contentions were correct, then it would be more difficult to know the moral values of different cultures and hence to know whether or not DMR is true. As before, this would not show that it is false (in fact, the point about heterogeneity might point the other way). However, we will see later that these contentions also pose challenges to MMR.
