Summarize Chapter 6 ("Of the Training of Black Men") in The Souls of Black Folk.

The chapter advocates the importance of higher education
of African Americans not only for themselves but for American civilization as a whole.
DuBois claims that African American college graduates have been "conservative, careful
leaders". Their education has allowed them to understand the importance of cooperation
between the races. Thus, they have not become mob agitators, but are performing much
needed work to construct a fairer and more peaceful society. To DuBois, denying
education to the nine million African Americans that live in America would lead them to
brood "over the wrongs of the past and the difficulties of the present" preventing them
to apply their talent to a constructive cooperation with the whites to the advantage of
American civilization.
