In "The Name of the Rose," Umberto Eco essentially presents an educative vision of some basic semiotic principles that infuse the textual form of a popular fictional genre--the detective story. In effect, it characterizes the postmodernization of the traditional "whodunnit" moving the genre from the realm of "the real" or the plausible into the realm of "the metaphysical" or the unthinkable. "The Name of the Rose" is a practical application in semiotics. Or, how the aesthetics of textual production as generated through the lexical signs and codes manifest the discursive text of a novel work. The semiotic twists and turns of the detective story facilitate this educational function and the purposeful transformation of the reader into an individual capable of appreciating and grasping the conflicting ideological viewpoints expressed through its dialogical structure. The detective genre enables the Umberto Eco to produce an educational narrative via the intricacies of plot in the detective story while teaching main aspects of semiotic theory.
