T.S. Eliot was one of the greatest literary critics of the 20th century in England. He devised several influential critical concepts, including the "objective correlative." The objective correlative refers to a set of objects, events, or situations that allow a poet to evoke a particular emotion in the reader, rather than stating the emotion directly. Eliot believed poets should "show" their emotions through an objective correlative, not just say them. His criticism argued that a work of art must be understood in the context of previous works. As a critic, Eliot had influence but was also faulted for personal biases and inconsistent standards.
