" I don’t know whether Asimov realized he was saying this as well, but as an old historical materialist, if only as an afterthought, he must have realized that he was saying too: No one here will ever look at you, read a word you write, or consider you in any situation, no matter whether the roof is falling in or the money is pouring in, without saying to him- or herself (whether in an attempt to count it or to discount it), 'Negro...' The racial situation, permeable as it might sometimes seem (and it is, yes, highly permeable), is nevertheless your total surround. Don’t you ever forget it...! And I never have. "
