How many of us are completely free of such scenarios? Who hasn't known, a little shamefully, the joys they bring? I suspect that what keeps us harmless from them is not, as many seem to believe, the maintenance of a strict frontier between the kingdoms of the fanciful and the actual, but the contrary: the permitting of a benign annexation of the latter by the former, so that our daily motions always cast a secondary other-worldly shadow and, at those moments when we feel inclined to turn from the more plausible and hurtful meanings of things, we soothingly find ourselves attached to a companion far-fetched sense of the world and our place in it.
