The celebrated opening image of 'The Love Song of J. Alfred Prufrock' is another case in point: Let us go then, you and I, When the evening is spread out against the sky Like a patient etherised upon a table... How, the reader wonders, can the evening look like an anaesthetised body? Yet the point surely lies as much in the force of this bizarre image as in its meaning. We are in a modern world in which settled correspondences or traditional affinities between things have broken down. In the arbitrary flux of modern experience, the whole idea of representation - of on thing predictably standing for another - has been plunged into crisis; and this strikingly dislocated image, one which more or less ushers in 'modern' poetry with a rebellious flourish, is a symptom of this bleak condition.
