Christopher Lasch

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.

The way that Dickens structured his books has a form that we most readily recognize now from, say, the great T.V. series, like 'The Wire' or 'The Sopranos.' There's one central plot line, but then from that spin off all kinds of subplots.
