 I am working at my Giffords. The problem of problems which bothers me, is the real transitoriness of things—and yet!!—I am equally convinced that the great side of things is weaving something ageless and immortal: something in which personalities retain the wonder of their radiance—and the fluff sinks into utter triviality. But I cannot express it at all—no system of words seems up to the job. (Unpublished letter archived by the Whitehead Research Project)
