Our noses too, and our eyes and ears, are political instruments, protesters. An aesthetic response is a political action. . . . We know instinctively, aesthetically, when a fish stinks, when the sense of beauty is offended. Standing for these moments — and these moments occur each day, within every airless office building, seated in each crippling chair, inundated by senseless noise and fattened on industrial food — standing for our responses, these aesthetic reverberations of truth in the soul, may be the primary civic act of the citizen, the origin of caution and of the precautionary principle itself, with its warnings to stop, look, and listen.
