Between the two authors, Booker T. Washington and W.E.B. Dubois, one would have to choose Booker T. Washington as the more plausible in regards to implementation and ability to accomplish the goal of racial equality.
Booker T. Washington espoused that blacks need to ignore the prejuice just long enough to rise up in the educational system, and then laugh all the way to the bank (so to speak). He believed that if the black man could meet or beat the white man at his own game, then there would be a recognition of equality. Unfortunately, his views were not as popular as Dubois and it can be argued is now the ancestor of affirmative action, which many believe has outlived its usefulness and only hurts minorities today.
How did the geography discourage the unity of the ancient Greeks? (How did it keep them seperated?)
