This volume assembles essential essays some published only posthumously, others obscure, another only recently translated by W. E. B. Du Bois from 1894 to early 1906. They show the first formulations of some of his most famous ideas, namely, "the veil," "double-consciousness," and the "problem of the color line." Moreover, the deep historical sense of the formation of the modern world that informs Du Bois's thought and gave rise to his understanding of "the problem of the color line" is on display here. Indeed, the essays constitute an essential companion to Du Bois's masterpiece published in 1903 as The Souls of Black Folk. The collection is based on two editorial principles: presenting the essays in their entirety and in strict chronological order. Copious annotation affords both student and mature scholar an unprecedented grasp of the range and depth of Du Bois's everyday intellectual and scholarly reference.
