If I want to understand something, I must observe, I must not criticize, I must not condemn, I must not pursue it as pleasure or avoid it as non-pleasure. There must merely be the silent observation of a fact.
I want to think quietly, calmly, spaciously, never to be interrupted, never to have to rise from my chair, to slip easily from one thing to another, without any sense of hostility, or obstacle. I want to sink deeper and deeper, away from the surface, with its hard separate facts.
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.
