From a piece about the early ’90s TV series Twin Peaks, which is apparently going to be revisited soon on Showtime:

Nostalgia is never only nostalgia, but the raw, reflexive appetite for something we can no longer access.

I confess, I’m not entirely sure what the author means by the first clause of that sentence, “Nostalgia is never only nostalgia,” but I really like the language she comes up with to describe the phenomenon: “the raw, reflexive appetite for something we can no longer access.” That certainly sounds like my emotional experience. The word “reflexive,” in particular, is… enlightening.
