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.”
