The School has often been called “Neo-Aristotelian,” though in the introduction to "Critics and Criticism" (and in other works, such as “Toward a More Adequate Criticism of Poetic Structure”) Crane argued strongly against that title. Regardless, Aristotle's "Poetics" and the method of inquiry he created played an important and obvious role in their works: Crane emphasized Form and Matter in his writings as inseparable entities within poetry, and frequently referred to Aristotle's distinction between imitative and non-imitative poetry. The prefix “Neo” is applied because of the modifications Crane makes to Aristotle's original theories in "Poetics".
