Students and instructors in the field, usually called "comparatists," have traditionally been proficient in several languages and acquainted with the literary traditions, literary criticism, and major literary texts of those languages. Some of the newer sub-fields, however, are more influenced by critical theory and literary theory, stressing theoretical acumen and the ability to consider different types of art concurrently, over high linguistic competence. The interdisciplinary nature of the field means that comparatists typically exhibit some acquaintance with translation studies, sociology, critical theory, cultural studies, religious studies, and history. As a result, comparative literature programs within universities may be designed by scholars drawn from several such departments. This eclecticism has led critics (from within and without) to charge that Comparative Literature is insufficiently well-defined, or that comparatists too easily fall into dilettantism, because the scope of their work is, of necessity, broad.
