  “The Souls of White Folk” can be read as Du Bois’s central contribution to the moral psychology of white supremacy; that is, as his account of the affective, motivational, and cognitive dispositions that constitute white supremacism as a morally vicious character trait—including, e.g., the dispositions passionately to hate black folk; to slander and murder black folk; and to believe that white folk are inherently better than black  folk.[26]  In “The White World” chapter of Dusk of Dawn, Du Bois complicates this earlier psychological portrait of the white supremacist, stressing the deeply ingrained persistence of her or his racist behavior. Du Bois argues, for example, that “the present attitude and action of the white world…is a matter of conditioned reflexes; of long followed habits, customs and folkways; of subconscious trains of reasoning and unconscious nervous reflexes” (Du Bois, 1940, 87). Productively building on Du Bois’s moral psychology, Shannon Sullivan (2006) and Terrance Macmullen (2009) have recently brought Du Bois into conversation with John Dewey to develop pragmatist, habit-centered accounts of the workings of white privilege.
