At bottom, whether we acknowledge it or not, the attention merchants have come to play an important part in setting the course of our lives and consequently the future of the human race, insofar as that future will be nothing more than the running total of our individual mental states. Does that sound like exaggeration? It was William James, the fount of American Pragmatism, who, having lived and died before the flowering of the attention industry, held that our life experience would ultimately amount to whatever we had paid attention to. At stake, then, is something akin to how one's life is lived. That, if nothing else, ought to compel a greater scrutiny of the countless bargains to which we routinely submit, and, even more important, lead us to consider the necessity, at times, of not dealing at all.
