Text: West's essay on Du Bois in Africana seemed a re-working of his essay on Du Bois in The Future of the Race . There is nothing new said in his Africana essay, and his presentism, his insistence on judging a historical figure by current moral standards, I find fatuous, just poor scholarship.
Entailment: West wrote about Du Bois and race.
Contradiction: West wrote about Du Bois and science.
