Of course, both [Oscar] Wilde & [Vladimir] Nabokov believe in many things, and these things emerge in their writing clearly - for Wilde, the folly of humankind and the (romantic) grandeur of the heroic, lone individual (not unlike Wilde himself); for Nabokov, the possibility of a kind of transcendence through a great, prevailing, superior sort of love (especially in Ada, the most self-congratulatory of novels.)
One of the qualities of writing that is not much stressed is its problem-solving aspect, having to do with the presentation of material: how to structure it, what sort of sentences (direct, elliptical, simple or compound, syntactically elaborate), what tone (in art, "tone" is everything), pacing. Paragraphing is a way of dramatization, as the look of a poem on a page is dramatic; where to break lines, where to end sentences.
