“…The traditional and still normative view, as portrayed by Rosmarin (1985; see also Altman, 1999;Benoit, 2000;Hauptmeier, 1987;Leitch, 1991), sees genres as entirely separable, mutually exclusive entities, whether they are more specifically conceived as natural species or their associated genetic codes (see Conley, 1986, for a review and demonstration of the truly traditional character of this perspective), social institutions (or ritually produced actions fitted to recurrent rhetorical situations-see Benoit, 2000;Hauptmeier, 1987;and Leitch, 1991, for partial reviews, and C. R. Miller, 1984, for a prominent example), psychological categories created for literary interpretation or composition (e.g., Swales, 1990), or Aristotelian natural kinds. 4 Further, this view portrays genres as possessing texts in an exclusive fashion; hence, even in the case of those espousing a genetic theory of genre (e.g., Jamieson, 1973) or those advocating cognitive prototype theory of genre (e.g., Fishelov, 1991;Swales, 1990), traditional scholars posit that texts that possess (enough of) certain features belong to one and only one genre (see also Gerhart, 1989).…”
