It is a good thing to write for the amusement of the public, but it is a far higher and nobler thing to write for their instruction, their profit, their actual and tangible benefit.
Mark TwainNarrative should flow as flows the brook down through the hills and the leafy woodlands...a brook that never goes straight for a minute, but goes and goes briskly, sometimes ungrammatically, and sometimes fetching a horseshoe of ยพ of a mile around and at the end of the circuit flowing within a yard of the path that it traversed an hour before; but always going and always following at least one law, always loyal to that law, the law of narrative, which has no law. Nothing to do but make the trip; the how of it is not important, so that the trip is made.
