20221 | Precision is only one of the virtues of a good definition [Zagzebski] |
Full Idea: Precision is but one virtue of a definition, one that must be balanced against simplicity, elegance, conciseness, theoretical illumination, and practical usefulness. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], III 2.1) | |
A reaction: Illumination looks like the dream virtue for a good definition. Otherwise it is just ticked as accurate and stowed away. 'True justified belief' is a very illuminating definition of knowledge - if it is right. But it's not very precise. |
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. |
