It goes without saying that when readers have their own understanding and position on the questions "What is literature?" or "What can literature do?" from the perspective of literary theory, reading the work becomes much easier, and even critical reading becomes possible.

From this perspective, this textbook covers a wide range of topics, from the essence and function of literature to the relationship between literature and surrounding academic disciplines and ideas, and even criticism of individual works.
Furthermore, by covering major British and American writers and critics from the 16th century, from Sir Philip Sidney to the current critic Terry Eagleton, it allows us to examine how critical perceptions have changed and developed in Anglo-American literature.
It is also structured in a variety of ways to enhance understanding of modern society and culture.
