W. E. B. Du Bois 
The Souls of Black Folk 

Herein lie buried many things which if read with patience may show the strange meaning of being black here at the dawning of the Twentieth Century. This meaning is not without interest to you, Gentle Reader; for the problem of the Twentieth Century is the problem of the color line. I pray you, then, receive my little book in all charity, studying my words with me, forgiving mistake and foible for sake of the faith and passion that is in me, and seeking the grain of truth hidden there. I have sought here to sketch, in vague, uncertain outline, the spiritual world in which ten thousand thousand Americans live and strive.
