I see where Anthony Stadlen is coming from.  Interesting how two people can read the same text in such different ways.  In the paragraph I quoted, I did not view Trilling as using the terms health and pathology in Freudian terms at all.  He certainly didn't say he was relying on Freud, and it seemed to me, in deference to Nabokov's intent, that he was staying away from Freudian interpretation (as much as Trilling could.)  I read the paragraph in the more ordinary usage of the word "health"--as a metaphor, not as a medical pronouncement:  the kind of meaning  Brian Boyd used to describe a good kind of love, versus passion-love.  As Nabokov put it in Sebastian Knight, “Girls of her type do not smash a man’s life—they build it.”
