1. Direct treatment of the "thing," whether subjective or objective.
2. To use absolutely no word that does not contribute to the presentation.
3. As regarding rhythm: to compose in sequence of the musical phrase, not in sequence of the metronome.
4. Complete freedom of subject matter.
5. Free verse was encouraged along with many other new rhythms.
6. Common speech language was used, and the exact word was always to be used, as opposed to the almost exact word.
A key characteristic of Imagism was Cubism. Basically cubism is another early 20th-century avant-garde art movement (think Picasso) in which objects are analyzed, broken up and reassembled in an abstracted form; rather than depicted objects from one viewpoint, the artist depicts the subject from multiple viewpoints to represent the subject in a greater context. This is exactly how I think of "The Wasteland." It contains broken, fragmented, and seemingly unrelated pieces of imagery so that the reader cannot see anything but a jumbled heap of broken images. However, Modernist poets promise to show their readers how to find meaning within these fragmentations, and I think this clearly illustrates Eliot's use of fragmentation in "The Wasteland" as well.
