Humor trades in incongruity. The practical joker pulls the chair out from under the guest of honor, revealing that he, no less than the rest of us mortals, is a helpless subject of gravity. The divine joke is to pull the gravity out from under the chair. In the divine comedy, we play the part of the fool, but this turns out to be our best role. For our folly conducts us to paradise, bringing us into the arms of the beloved (as in the Shakespearean comedies of mismatched loves resolved) and lifting us to the court of the Most High, where by all logic and etiquette we most certainly do not belong. When finally we come to prostrate ourselves before the divine throne, it will very likely be because we have tripped.
