Chomsky: And here comes Bilbo Baggins. Now, this is, to my mind, where the story begins to reveal its deeper truths. In the books we learn that Saruman was spying on Gandalf for years. And he wondered why Gandalf was traveling so incessantly to the Shire. As Tolkien later establishes, the Shire’s surfeit of pipe-weed is one of the major reasons for Gandalf’s continued visits.Zinn: You view the conflict as being primarily about pipe-weed, do you not?
Chomsky: Well, what we see here, in Hobbiton, farmers tilling crops. The thing to remember is that the crop they are tilling is, in fact, pipe-weed, an addictive drug transported and sold throughout Middle Earth for great profit.
Zinn: This is absolutely established in the books. Pipe-weed is something all the Hobbits abuse. Gandalf is smoking it constantly. You are correct when you point out that Middle Earth depends on pipe-weed in some crucial sense, but I think you may be overstating its importance. Clearly the war is not based only on the Shire’s pipe-weed. Rohan and Gondor’s unceasing hunger for war is a larger culprit, I would say.
Chomsky: But without the pipe-weed, Middle Earth would fall apart. Saruman is trying to break up Gandalf’s pipe-weed ring. He’s trying to divert it.
Zinn: Well, you know, it would be manifestly difficult to believe in magic rings unless everyone was high on pipe-weed. So it is in Gandalf’s interest to keep Middle Earth hooked.
