Objective Correlative?
T.S. Eliot, in an essay on Hamlet, discussing the Objective Correlative
“The only way of expressing emotion in the form of art is by finding an ‘objective correlative’; in other words, a set of objects, a situation, a chain of events which shall be the formula of that particular emotion; such that when the external facts, which must terminate in sensory experience,are given, the emotion is immediately evoked.” (qtd. in J. A. Cuddon’s Dictionary of Literary Terms, page 647)
