Kaplan pursues several issues raised in Eissler's appendix, which discusses the relevance of positive audience responses and the doxaletheic function, the process by which reality testing of the artist survives a temporary loss of distinction between internality and externality. Eissler feels the genius requires certain positive responses from his environment to protect him from a breakdown of his mental functioning. Among the points that Kaplan makes is that in the artist's audience there is at work a remnant of a creative gift, too weak in most instances to produce a work of art, but sufficiently functional to enable a complex response to an art object.
