That actually is a good example of a brittle requirement,
Yeah, good point. I’m entirely convinced. Even for an apparently straight-forward category like ‘bird’, there’s not a single necessary condition you can point to. Even if there are some examples of categories with necessary conditions (I don’t know), this is evidence that the necessary conditions aren’t an intrinsic part of the way we structure a concept.
