The division of one day from the next must be one of the most profound peculiarities of life on this planet. We are not condemned to sustained flights of being, but are constantly refreshed by little holidays from ourselves. We are intermittent creatures, always falling to little ends and rising to new beginnings. Our soon-tired consciousness is meted out in chapters, and that the world will look quite different tomorrow is, both for our comfort and our discomfort, usually true. How marvelously too night matches sleep, sweet image of it, so nearly apportioned to our need. Angels must wonder at these beings who fall so regularly out of awareness into a fantasm-infested dark. How our frail identities survive these chasms no philosopher has ever been able to explain.
