The book presents the various viewpoints that poetics, literary history and Western rhetoric have adopted throughout Western history. The aim of poetics is to render the specificity of the literary discourse by either highlighting the extra literary generative forces or by focusing on the intrinsic study of literary works. Rhetoric chiefly places emphasis on the verbal effects of discourses whereas literary history predominantly examines the temporal succession of the literary systems or of the literary institution. The author focuses on the three sections: poetics, rhetoric, and literary history and provides an introductory study on the subject of reference.
