Modern day university and college Great Books Programs are inspired by the Great Books movement that began in the United States during the 1920s. The aim of such programs is a return to the Western Liberal Arts tradition in education, as a correction to the extreme disciplinary specializations common within the academy. The essential component of such programs is a high degree of engagement with whole primary texts, the Great Books. The curricula of Great Books programs often follow a canon of texts considered more or less essential to a student's education, such as Plato's "Republic", or Dante's "Divine Comedy". Such programs often focus exclusively on Western culture. Their employment of primary texts dictates an interdisciplinary approach, as most of the Great Books do not fall neatly under the prerogative of a single contemporary academic discipline. Great Books programs often include designated discussion groups as well as lectures, and have small class sizes. In general students in such programs receive an abnormally high degree of attention from their professors, as part of the overall aim of fostering a community of learning.
