Questions on Aristotle's Prior Analytics and Questions on Aristotle's Posterior Analytics by two others were once attributed to this thinker. For 10 points each:
[10e] Name this Scholastic whose Ordinatio introduced an individuating concept of "thisness," or haecceity (heck-SEE-uh-tee). His British place of birth became a word for stupidity that names a conical cap.
ANSWER: John Duns Scotus [or John Duns; or Johannes Duns; or Doctor Subtilis; reject "John Scotus Eriugena"] [for whom the dunce cap is named]
[10m] Pseudo-Scotus names a paradox in which an argument claims not to have this property. An argument has this property only if the truth of the premises logically guarantees the truth of the conclusion.
ANSWER: validity [or word forms, such as being valid; reject "soundness"]
[10h] Pseudo-Scotus sometimes names this logical principle, by which a contradiction may be used to derive any other statement. He gave the example that "If Socrates exists and Socrates does not exist, then Plato is a donkey."
ANSWER: principle of explosion [or ex contradictione quodlibet; or deductive explosion] [the Pseudo-Scotus above is the commentator on the Prior Analytics, and not the Pseudo-Scotus who commentated on the Posterior Analytics]
