Ezra Pound in his “In a Metro Station...” illustrates in its most simple form the image-complex relation, which is providing an image and the reader
the only way of expressing emotion in the form of art is by finding an object...
Set of objects is above the water, evoked emotions is under the water. This is the image-complex.
Eliot would say that I chose the object and you will choose what I complex I intended (determinism).
Pound would say I choose the object and you choose whatever complex you want
An objective correlation between the object and the emotion. They cannot be separated, is what Eliot would say.
