Back in the day, I was apprehensive about reading Dickens too. I believe that, when I took up my first unabridged novel by him, Oliver Twist, I thought I would mark paragraphs that I could skip if I read it again. ....I marked maybe two paragraphs -- ?
Dickens takes adjustment because we are used to novels with short paragraphs and enormous stretches of dialogue, if we read current popular fiction. That is, we're used to books influenced by the popular cinema. But I don't think Dickens is inherently hard to read. We just need to become receptive. Then we become like Nabokov, who begins his lecture on one of the Dickens novels by inviting us -- I don't remember his exact words -- to revel in Dickens, feast on Dickens. Dickens seems to me to be a really good writer of Dickens novels, and that includes his "rhetorical strategies," as it might have been put in the past half-dozen decades or so.
Now I find that it's the contemporary novel of 700 pages, mostly of dialogue, that I can't stick with. I can't read fast and casually enough to enjoy them.
