He emphasizes that literary study is not limited to the study of general literary characteristics, such as metaphor, rhythm, the type of hero, and the nature of the event. Rather, the study may extend beyond this type of analysis, which abstracts general characteristics or abstracts them to link them to a single genre, to the relational network between more than one text and more than one genre. Here, we enter the field of genre theory.
