To suggest that literature is simply another genre of fiction, like the Western or the Romance, is to ignore a fact that…genres are distinguished from one another principally by looking at the story-type, the plot. Insofar as works of literature fall into distinct types, they do so on the basis of features other than plot, such as theme or character. So different kinds of great literature may indeed be categorized as falling into certain “types,” but these types are not thereby genres, because genres are distinguished from one another according to their plot. This matters because plots are powerful emotion-producing machines.
It is the scientist’s “being-in-the-world” that allows her to describe planets and bacteria, “things and subhuman organisms,” but the “being-in-the-world” of the layman occupies what Percy calls a “different sort of reality,” resting upon the linguistic and social ties that constitute a “non-material, non-measurable entity.” And what holds true of our triadic relationships also goes for us as individuals. A “material substance cannot name or assert a proposition,” which accordingly means, Percy concludes, that “the initiator of a speech act” is also something that the natural sciences are incapable of recognizing: “The agent is not material.”
