Actually, the point of The Wasteland is exactly that -- not to make sense. Or rather, to make sense only to T.S. Eliot. The inability of people to communicate with each other was a Central Theme that Eliot worked with. Take The Love Song of J. Alfred Prufrock -- a poem about a lonely middle-aged man who can't seem to connect with anyone else (or to get play -- they were pretty well connected in eliot's mind) -- a central theme of Modernism but im off topic now.

The point of all the different references and languages is that they only make sense to eliot or leastways that the only person that they ALL make sense to is Eliot. Hence, it is impossible for one person to truly understand another because they do not share the same set of experiences.

Nope, while this may be B.S. it's good B.S. -- hit the nail right on the head.

If this is The Worst Paper you've ever written I know a few people who'd like to kill you and eat your brain.

Caveat: The Wasteland is a complex and beautiful poem and this is by no means the only reading or the only way it expresses its theme. However, it is the most prominent and the most obvious
