"Beautiful, fragile, fleeting, the sunrise shell; but not, for all that, illusory. Because it is not lasting, let us not fall into the cynic's trap and call it an illusion. Duration is not a test of true or false. The day of the dragon-fly or the night of the Saturnid moth is not invalid simply because that phase in its life cycle is brief. Validity need have no relation to time, to duration, to continuity. It is on another plane, judged by other standards. "And what is actual is actual only for one time and only for one place." The sunrise shell has the eternal validity of all beautiful and fleeting things."
