This essay is an attempt to set forth more clearly than has hitherto been done the effect which the Negro has had upon American life. Its thesis is that despite slavery, war and caste, and despite our present Negro problem, the American Negro is and has been a distinct asset to this country and has brought a contribution without which America could not have been; and that perhaps the essence of our so-called Negro problem is the failure to recognize this fact and to continue to act as though the Negro was what we once imagined and wanted to imagine him—a representative of a subhuman species fitted only for subordination.
