One of the ways of looking at some art is to see it as an exploration of
perception, a looking for new perceptions, new methods of perception, of
shaking up the senses so they get out of their ruts and are prompted
to look at the world in new ways.
If that was what Eliot/Pound were doing in the early 20th C. then
their work can be seen to a certain extent as crude ore presented
for the sharpening of whosever senses. If it is meant as such an
instruement, then expecting the poet to explain the instrument may
be expecting the impossible.
