This can then go pretty easily to any number of values you want -- even reals (it is Sum and Product tht get you). << .

No, I mean something like "beautifulish, on the threshold of being wholly beautiful, but not quite wholly beautiful, but closer to being wholly beautiful and to being wholly not beautiful, e.g. satisfying .8 of the criteria for being beautiful, where something definitely beautiful satisfies .ro, and something definitely not beautiful satisfies .no". "Almost beautiful" would be ambiguous between "slightly less than pi ro" and "slightly less than pi no". It's like the difference between being outside a room but close to the entrance and being most of the way across the threshold. >> I would see And's case as a function on beautiful and xorxes pretty usually as either a truth value comment or a quantitative evaluation (these are the hardest two to separate even though they are the furthest apart conceptually). |
