A dominant “knowing irony” can suggest the kind of uncertainty, or reluctance to take any side in some important dispute, which is inconsistent with the high seriousness and mythic ambition of great Westerns. In the crisis situations portrayed in Westerns, indulge such an irony and you begin to sound like a Lee Marvin character, a cynic. The great problem in great Westerns is the possibility of and the nature of and especially the cost of civilized life itself.
To suggest that literature is simply another genre of fiction, like the Western or the Romance, is to ignore a fact that…genres are distinguished from one another principally by looking at the story-type, the plot. Insofar as works of literature fall into distinct types, they do so on the basis of features other than plot, such as theme or character. So different kinds of great literature may indeed be categorized as falling into certain “types,” but these types are not thereby genres, because genres are distinguished from one another according to their plot. This matters because plots are powerful emotion-producing machines.
