W. E. B. Du Bois [SEP] "The Souls of Black Folk"
In an effort to portray the genius and humanity of the black race, Du Bois published "The Souls of Black Folk" (1903), a collection of 14 essays. James Weldon Johnson said the book's effect on African Americans was comparable to that of "Uncle Tom's Cabin". The introduction famously proclaimed that "the problem of the Twentieth Century is the problem of the color line". Each chapter begins with two epigraphs – one from a white poet, and one from a black spiritual – to demonstrate intellectual and cultural parity between black and white cultures. A major theme of the work was the double consciousness faced by African Americans: being both American and black.
