W.E.B. Du Bois: “This knowledge makes them now embarrassed, now furious.”

The silently growing assumption of this age is that the probation of races is past, and that the backward races of to-day are of proven inefficiency and not worth the saving.

Around us the history of the land has centred for thrice a hundred years; out of the nation’s heart we have called all that was best to throttle and subdue all that was worst; fire and blood, prayer and sacrifice, have billowed over this…

Such an assumption is the arrogance of peoples irreverent toward Time and ignorant of the deeds of men.

So wofully unorganized is sociological knowledge that the meaning of progress, the meaning of “swift” and “slow” in human doing, and the limits of human perfectability, are veiled, unanswered sphinxes on the shores of science.
