Recent discussion of VN & Freud on NABOKV-L following Karshan's TLS write-up was one catalyst for returning to Pale Fire.
Thoughts on moral psychology in an LRB review of a new version of Samuel Johnson's Lives of the Poets was another.

As Jeffrey Meyers put it: "Pale Fire reveals how profoundly Nabokov identified with the character of Samuel Johnson."
Too much of a ramble to repost on the list, with all the embedded links, but I trust it will be of interest.
It is my hope that this opens the door to more serious scholarship on Johnson's influence on Nabokov.
And I look forward to Karshan's "Vladimir Nabokov and the Art of Play".
