The Chicago School of literary criticism was a form of criticism of English literature begun at the University of Chicago in the 1930s, which lasted until the 1950s. It was also called Neo-Aristotelianism, due to its strong emphasis on Aristotle's concepts of plot, character and genre. It was partly a reaction to New Criticism, a then highly popular form of literary criticism, which the Chicago critics accused of being too subjective and placing too much importance on irony and figurative language. They aimed instead for total objectivity and a strong classical basis of evidence for criticism. The New Critics regarded the language and poetic diction as most important, but the Chicago School considered such things merely the building material of poetry. Like Aristotle, they valued the structure or form of a literary work as a whole, rather than the complexities of the language. Despite this, the Chicago School is considered by some to be a part of the New Criticism movement.
