Tom Hillman collected these three posts with approbation.
Olga added a guest post at Stephen’s joint:
Shawn Marchese at “The Prancing Pony” ponders what elves must smell like

Because I have just survived a course on literary theory, I can see that the world has been spared from an outbreak of Newest Criticism by sheer luck. After all, the world has endured (says Wikipedia) historical and and biographical criticism, New Criticism, formalism, Russian formalism, structuralism, post-structuralism, Marxism, normal feminism and French feminism, post-colonialism, new historicism, deconstruction, reader-response criticism, and psychoanalytic criticism. To which our lecturers added performance theory, queer theory, native-american theory, and even oceanic theory.
None of us is (currently) a college professor, else we’d have beefed up our essays with citations, peer-reviewed each others’ work and approved it for publication, and now we’d be the founders of Olfactory Theory.
