Over at The Toast, “How to Tell if You Are in a Logic Puzzle.”
Because heaven knows, Logic Puzzle Land has only a tangential relationship to Real Life Land.
Obligatory writing reference: When constructing plots and figuring out character motivations, remember that Fiction Land generally strives to reflect Real Life Land, not Logic Puzzle Land. There are a few instances where it’s closer to Logic Puzzle Land – the strict-form allegory, for example, or the roman à clef – but those are the exceptions rather than the rule.
(Now that I think of it, that’s a good way to distinguish between an allegorical work and one that merely makes heavy use of symbolism and metaphor: If the workings of the plot and the actions of the characters appear to be taking place in Logic Puzzle Land, you’re probably dealing with an allegory.)
