lol @ this thread
This was originally going to be about Humbert Humbert (for those of you who haven't read Lolita, he's the paedo protagonist).
Essentially, I was initially thinking Se ego for HH. Then it hit me that that was a ridiculous suggestion next to Si. He is quite clearly Si ego; and almost indubitably Si base. I was stuck after that, although SEI is more likely IMO. Then that got me thinking about Nabokov.
Basically, HH is a poetic kind of guy, but he's a mouthpiece (well, maybe not mouthpiece) for Nabokov. Nabokov clearly is a sensory type to write in the way he does. And why not Si ego?
