Newmarch had always, in our time, carried itself as the great asylum of the finer wit, more or less expressly giving out that, as invoking hospitality or other countenance, none of the stupid, none even of the votaries of the grossly obvious, need apply; but I could luckily at present reflect that its measurements in this direction had not always been my own, and that, moreover, whatever precision they possessed, human blandness, even in such happy halls, had not been quite abolished. There was a sound law in virtue of which one could always--alike in privileged and unprivileged circles--rest more on people's density than on their penetrability. Wasn't it their density too that would be practically nearest their good nature? Whatever her successive partners of a moment might have noticed, they wouldn't have discovered in her reason for dropping them quickly a principle of fear that they might notice her failure articulately to keep up. My own actual vision, which had developed with such affluence, was that, in a given case, she could keep up but for a few minutes and was therefore obliged to bring the contact to an end before exposure. I had consistently mastered her predicament: she had at once to cultivate contacts, so that people shouldn't guess her real concentration, and to make them a literal touch and go, so that they shouldn't suspect the enfeeblement of her mind. It was obviously still worth everything to her that she was so charming. I had theorised with Mrs. Brissenden on her supposititious inanity, but the explanation of such cynicism in either of us could only be a sensibility to the truth that attractions so great might float her even a long time after intelligence pure and simple should have collapsed.
