... So much that in reality is simply 'given' has to be decided when you're writing fiction. Facts have to be represented by pseudo facts, labouriously invented and painstakingly described. The reader must memorize these facts in order to follow your story, but they are flushed away almost as soon as the book is finished, to make room for another story. Before long, nothing remains in the reader's memory but a name or two, a few vague impressions of people, an indistinct recollection of the plot, and the general sense of having been entertained, or not as the case may be. It's frightening to think how many novels I must have read in my lifetime, and how little I retain the substance of most of them.From Thinks by David Lodge
Isn't that just so true? Do you ever feel scared by how quickly the details of a book leach away from you? How much do you actually retain in your head of your favourite books?
