This article asserts that Du Boisian sociology included a strong role for r
acial prejudice in analyzing the conditions and dynamics of African America
n social life. The article examines Du Bois's empirical social scientific l
egacy with a special focus on The Philadelphia Negro and how he treated rac
ial prejudice in this seminal work. It then examines the turn away from a c
oncern with racial prejudice in modern sociological analysis and identifies
the necessity of returning to the theoretical holism exemplified by Du Boi
s if sociological theory on race and racism are to advance.
