The Logician And The God-Emperor
Slate Star Codex, December 5, 2013
Abstract
This short story presents two scenarios illustrating the misapplication of formal logic in social contexts. In the first, a logician granted a choice between two princesses—one with inheritance but plain, the other beautiful but without inheritance—exploits the ambiguity of the conjunction “or” to bed both. The God-Emperor, unaware of the distinction between inclusive and exclusive or, punishes the logician. The second scenario involves a trial by ordeal where the logician, presented with seven chests containing six skulls and one key to his freedom, correctly solves a logic puzzle to locate the key. Despite this success, the God-Emperor, exploiting the distinction between material implication (“if”) and logical equivalence (“if and only if”), orders his execution. The humor derives from the contrast between the logician’s rigid interpretation of language and the God-Emperor’s manipulative use of ambiguity in ordinary language. – AI-generated abstract.
