Chapter 7 argues that the word which brings the “nasty, grim little tale” of Willa Cather’s The Professor’s House to the surface is “sin” and that the hermeneutic that makes sense of the Professor’s love-driven crisis of will is German-American Catholic. The starting point of this revisionist reading is non-controversial; The Professor’s House frames one great homosocial, alternatively domestic, putatively anti-capitalist intergenerational romance (Tom Outland’s reminiscences of his cowpoke buddy, Roddy Blake) inside another (Professor St. Peter’s idealization and idolization of Tom Outland), both of which seem to be as pure of heart—and of fluid exchange—as the pristine air and water of Outland’s Blue Mesa. But the women of the novel, especially wife Lillian and the two daughters, would seem to have a different story to tell, regarding the Professor’s investments in Outland and Outland’s retreat with Roddy and what male-male romance has in it for women—a subtext of feminist perspective and women’s values that emerges, in remarkable clarity, as if by miracle, from the fractured yet relentless Catholic insinuations of the novel: a veritable catechism of silent revelations and muted insistences beginning, in fact, with the reclamation of the discourse and provenance of sin. It comes as a surprise, then, that a novel as sophisticated in sociological inquiry, sexual wisdom, and experimental form as The Professor’s House—one of the most academically revered, or at least attended to, novels in the current modernist canon—can and does have a moral—indeed, it tests for morality.
