Some of the influential thinkers... Hagel, Marx, Engels, Durkheim, Nietzsche...and DuBois.
DuBois? Yes, W. E. B. is on the list. The Souls of Black Folk is worth reading. Have read it once as a teen and need to read it again as an adult.
I could be a homer why DuBois is up there. Here's the truth though...he was a great thinker that happened to be black; not a great black thinker. My other favorite, Marcus Garvey was the same. Garvey in the 1920s would draw silly crowds here...so huge the government would keep tabs on what he was doing. The Black Star Line was a hell of a thing. Two great men, also Pan Africanists...wished that they had collaborated, really.
