Americans are as unlike any other white people in the world as it is possible to be. I do not think, for example, that it is too much to suggest that the American vision of the world--which allows so little reality, generally speaking, for any of the darker forces in human life, which tends until today to paint moral issues in glaring black and white--owes a great deal to the battle waged by Americans to maintain between themselves and black men a human separation which could not be bridged.
