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 for that particular emotion; such that when the external facts, which must terminate in sensory experience, are given, the emotion is immediately evoked.
Every experience is a paradox in that it means to be absolute, and yet is relative; in that it somehow always goes beyond itself and yet never escapes itself.
From a purely external point of view there is no will; and to find will in any phenomenon requires a certain empathy; we observe aman's actions and place ourselves partly but not wholly in his position; or we act, and place ourselves partly in the position of an outsider.
The poet's mind is in fact a receptacle for seizing and storing up numberless feelings, phrases, images, which remain there until all the particles which can unite to form a new compound are present together.
