What is the theme in Voices from the Harlem Renaissance by Nathan Irvin Huggins?

Alain Locke is the first to mention the words "coming of age" within this book, which is actually a series of essays, though many talk about the concept in different terms. In the case of Locke, he points out that the plight of the Negro has gained world-wide attention and that this attention has created some opportunities and responsibilities for the Negro. The ability and willingness to deal with this new responsibility requires a different kind of leader than that of ages past.
