"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. If you examine any of Shakespeare’s more successful tragedies, you will find this exact equivalence; you will find that the state of mind of Lady Macbeth walking in her sleep has been communicated to you by a skilful accumulation of imagined sensory impressions; the words of Macbeth on hearing of his wife’s death strike us as if, given the sequence of events, these words were automatically released by the last event in the series. The artistic “inevitability” lies in this complete adequacy of the external to the emotion; and this is precisely what is deficient in Hamlet. Hamlet (the man) is dominated by an emotion which is inexpressible, because it is in excess of the facts as they appear."
"The intense feeling, ecstatic or terrible, without an object or exceeding its object, is something which every person of sensibility has known; it is doubtless a study to pathologists. It often occurs in adolescence: the ordinary person puts these feelings to sleep, or trims down his feeling to fit the business world; the artist keeps it alive by his ability to intensify the world to his emotions."
