Literary criticism (or literary studies) is the study, a genre of arts criticism, evaluation, and interpretation of literature. Modern literary criticism is often influenced by literary theory, which is the philosophical discussion of literature's goals and methods. Though the two activities are closely related, literary critics are not always, and have not always been, theorists.
Whether or not literary criticism should be considered a separate field of inquiry from literary theory is a matter of some controversy. For example, the Johns Hopkins Guide to Literary Theory and Criticism draws no distinction between literary theory and literary criticism, and almost always uses the terms together to describe the same concept. Some critics consider literary criticism a practical application of literary theory, because criticism always deals directly with particular literary works, while theory may be more general or abstract.
Literary criticism is often published in essay or book form. Academic literary critics teach in literature departments and publish in academic journals, and more popular critics publish their reviews in broadly circulating periodicals such as The Times Literary Supplement, The New York Times Book Review, The New York Review of Books, the London Review of Books, the Dublin Review of Books, The Nation, Bookforum, and The New Yorker.
Literary criticism is thought to have existed as far back as the classical period. In the 4th century BC Aristotle wrote the Poetics, a typology and description of literary forms with many specific criticisms of contemporary works of art. Poetics developed for the first time the concepts of mimesis and catharsis, which are still crucial in literary studies. Plato's attacks on poetry as imitative, secondary, and false were formative as well. The Sanskrit Natya Shastra includes literary criticism on ancient Indian literature and Sanskrit drama.
Later classical and medieval criticism often focused on religious texts, and the several long religious traditions of hermeneutics and textual exegesis have had a profound influence on the study of secular texts.
