Your understanding is really not very good ~ ~
The author is obviously Nabokov.
Who's humbert? Do you want to ask after reading this book?
Humbert is the hero of this novel. In the postscript, the author points out that this character and other characters are all made up by him. So there is no doubt that this story does not exist in reality. (Even if there is an author, there should be no similar experience. At least this book is not documentary literature, but a novel. )
Because of the different versions, in some books, the protagonist is humbert, and in some books, the translated names are slightly different.
See:
1956, Nabokov pointed out in the article "Talking about a book called Lolita": "I am neither a reader nor an author of sermon novels. ..... "Lolita" has no moral significance. In my opinion, a fictional work exists only because it provides us with what I call aesthetic pleasure. "
Second, the preface. The author is not afraid of publishing or anything. In fact, this is obviously a fictional story. How can anyone hold him accountable? He was under great pressure from public opinion, but that was because the content of this book caused great repercussions in the society at that time. Everyone is more exclusive and thinks that the content of the book is unhealthy.
The author prefaces the name of Dr. XXX because, of course, you have to understand that this Dr. XXX does not exist. It is also a fictional character of the author. So this fictional doctor edited the manuscript.
Why is it related to mental illness? This is the need of his story content arrangement. Only mental patients can do such ridiculous things ~ after all, it was hard to imagine at that time. This is the author's idea.
From the writer's original intention, creating Lolita is like "writing a beautiful mystery". It is not so much an eternal truth about human beings as a word game full of aesthetic ecstasy.
So the so-called rhetoric related to mental illness is also fabricated by the author. It was all made up by the author. Thank you.
