--more exactly in storymaking, ... Aristotle declares in effect that since real life now and then includes unlikely coincidences both idle and consequential ... a storymaker may legitimately deploy such a possible-though-improbable happenstance to begin the tale or to give its plot-screws an early turn. Thereafter, however, the Plausible (even when strictly impossible) is ever to be preferred to the Possible-but-Unlikely; and in the of a plot, most particularly, coincidence ought to be eschewed. let no god on wires drop down at climax-time to rescue the storymaker from whatever dramaturgical corner his want of experience, talent, or judgment has painted him into.
