  We find in Rehberg some standard historicist tropes before they became widespread in the nineteenth century.  Like Herder and Möser, he taught that each nation is an organic whole, a unique individual, which cannot be reduced down to the mere sum of its members.  Each nation has a singular and characteristic spirit (Volksgeist), which pervades every aspect of its life, and which persists over the generations. This meant for Rehberg, as later historicists, that moral and political values are sui generis and incommensurable, so that we should not judge one nation or epoch by the values of another.  Rehberg also shared some of Möser's skepticism about the natural law tradition, which attempted to formulate universal values or moral standards above all the changes of  history.[49]  He too believed that these values often turned out to be the product of their own time and place, that they rested upon illicit generalizations from the values of one culture.
