20220 | Objection by counterexample is weak, because it only reveals inaccuracies in one theory [Zagzebski] |
Full Idea: Objection by counterexample is the weakest sort of attack a theory can undergo. Even when the objection succeeds, it shows only that a theory fails to achieve complete accuracy. It does not distinguish among the various rival theories. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], III 2.1) | |
A reaction: Typically counterexamples are used to refute universal generalisations (i.e. by 'falsification'), but canny theorists avoid those, or slip in a qualifying clause. Counterexamples are good for exploring a theory's coverage. |
