We teach our children one thing only, as we were taught: to wake up. We teach our children to look alive there, to join by words and activities the life of human culture on this planet's crust. As adults we are almost all adept at waking up. We have so mastered the transition we make a hundred times a day, as, like so many will-less dolphins, we plunge and surface, lapse and emerge. We live half our waking lives and all of our sleeping lives in some private, useless, and insensible waters we never mention or recall. Useless, I say. Valueless, I might add -- until someone hauls their wealth up to the surface and into the wide-awake city, in a form that people can use.
