QUOTE : They don't deal with any basic difference in human nature between black and white..., they only study the effects of environment on human nature. You place the white man in the ghetto, deprive him of educational advantages, arrange it so he has to struggle hard to fulfill his instinct for self-respect, give him little physical privacy and leisure time, and he would after a time assume the same characteristics you attach to the Negro. These characteristics don't spring from whiteness or blackness, but from a man's conditioning.
