This note is just a quotation of a paragraph (from the website Reading group center) with which I totally agree and empathyse:
The last lines of Lolita are: “I am thinking of aurochs and angels, the secret of durable pigments, prophetic sonnets, the refuge of art. And this is the only immortality you and I may share, my Lolita”. What is the meaning of this passage? What does art offer Humbert and his beloved that sexual passion cannot? Is this aesthetic appeal merely the mask with which Humbert conceals or justifies his perversion, or is the immortality of art the thing that Humbert and his creator have been seeking all along? In what ways is Lolita at once a meditation on, and a re-creation of, the artistic process?
