Crass Stupidities Shall Not Be Played Upon the Reader

Crass stupidities shall not be played upon the reader . . . by either the author or the people in the tale.

The personages of a tale shall confine themselves to possibilities and let miracles alone; or, if they venture a miracle, the author must so plausibly set it forth as to make it look possible and reasonable.

The author shall make the reader feel a deep interest in the personages of his tale and in their fate.
