That works a bit better, at least for the art example. A better example of where you'd best "define" a set by memorising all of it's members might be the morality of a particular culture. For instance, some African tribes consider it evil to marry someone whose sibling has the same first name as oneself. Not only is it hard to put into words, in English or Ju|'hoan, a definition of "bad" (or |kàù) which would encompass this, but one couldn't look at a bunch of other things that these tribes consider bad and infer that one shouldn't marry someone who has a sibling who share's one's first name. Better to just know that that's one of the things that is said to |kàù in that culture.

Sure. Though even in cases like that, humans have a way of generalizing these sorts of things -- that is, of inferring an intensional definition which they extend, rather than treating the set strictly extensionally. It would not surprise me if after a few generations such a community came to consider marrying someone whose parent has the same first name as oneself to be |kàù, for example.

If I recall correctly, they actually do. It falls under their incest taboo. So "bad" in any culture could probably be defined by a list of generalised principals which don't necessarily share any characteristics other than being labelled as "bad".

Yup, more or less agreed.
