Not Out Of Africa: How "Afrocentrism" Became An Excuse To Teach Myth As History by Mary Lefkowitz
http://www.amazon.com/Not-Out-Africa-Afrocentrism-Republic/dp/046509838X-- Mary Lefkowitz takes aim at the basic claims of leading proponents of Afro-centrism, in this expansion of her New Republic article exposing flaws in the argument that black Africans were responsible for the great civilizations of Egypt and Greece that brought praise from historians and criticism from Afrocentrists. Lefkowitz argues that the Greeks' African heritage touted by Senegalese scholar Cheikh Anta Diop is based upon a single dubious source and that Egyptians never considered themselves black Africans, in fact, that they consciously disassociated themselves from blacks. She argues that the legacy of these two cultures remains so rich even foes of European civilization want to claim that legacy for themselves.
Black Athena Revisited by Mary Lefkowitz
-- Two classical scholars at Wellesley College have edited a collection of 20 articles, all attacking Martin Bernal's controversial interpretation of classical culture, Black Athena (Vol. 1, LJ 12/87; Vol 2, Rutgers Univ. Pr. 1991). The authors, experts in a variety of disciplines, including archaeology and linguistics as well as history and classics, criticize Bernal's two central contentions?that ancient Greek thought and culture derived largely from Egypt and that 19th-century scholars hid this fact for racist reasons. These arguments, claim Bernal's critics, are based largely on bad scholarship and ideological agendas.
Afrocentrism: Mythical Pasts and Imagined Homes by Stephen Howe
-- Afrocentrism, asserts Oxford historian Howe in this forceful scholarly critique, is a dogmatic ideology promoting a mythical vision of the past that involves an erroneous belief in fundamentally distinct African ways of knowing and feeling. Using archaeological and other studies, he refutes the claims of influential Afrocentrist Senegalese historian Cheikh Anta Diop, who held that ancient Egypt was a black African civilization and that a single cultural system unified the African continent.
