A now famous term used by T.S. Eliot in an essay on Hamlet (1919).The relevant
passage is (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).

Eliot goes on to suggest hat in Lady Macbeth' sleepwalking speech and in the speech that
Macbeth makes when he hears of his wife's death, the words are completely
adequate to the state of mind; whereas in Hamlet the prince is "dominated
by a state of mind which is in excess of the facts as they appear".

These observations have provoked a good deal of debate.

Hamlet is a critical analisys written in 1919.

DETACHED = distaccato

 Elliot, J. Joyce and V. Woolf looked for impersonality and objectivity in order to better render feelings

that are something abstract, very difficult to describe.
