I. Racist Propositions Appiah distinguishes three importantly different ideas relevant to race and racism: Racialism: ...there are heritable characteristics, possessed by members of our species, that allow us to divide them into a small set of races, in such a way that all the members of these races share certain traits and tendencies with each other that they do not share with members of any other race. These traits and tendencies characteristic of a race constitute, on the racialist view, a sort of racial essence; and it is part of the content of racialism that the essential
