But operating within the minds of each is a set of epistemic practices that Troncoso deftly contrasts. When juxtaposed, the Nietzschean valor of Sanchez, the Christian pragmatism of Sassolini and the blind inductivism of Rosselli make for a sustained, intellectual tension that perfectly complements the narrative one. If Troncoso occasionally tips his hand, as _he_does when Helmut self-consciously asks ``What was morality anyway?'', or when the street-wise Rosselli puts forth a rather academic-sounding theory of racial division, the author is careful never to make the conflict between his characters' ``truths'' too explicit. <sep>, Pronoun: he <sep>, A: Helmut <sep>, B: Rosselli
