Joy (n.) has no place: there are joyful thoughts but no toothache-ish ones — and do you notice the nature of zero when eating no apple?
Joy (n.) is pictured as a face bathed in light, rays streaming from it — not because joy resembles light, but because they are associated, perhaps as arbitrarily as a word and its sound.
Joy (n.) has an expression — but how does one know it is not the expression of some bodily pain? An important question.
Joy (n.) on a walk goes with physical well-being — but how marvellous all this is! does not mean things are giving me pleasant bodily feelings.
Joy (n.) is not felt anywhere, even when its trigger is the smell of a flower; we do not say we are joyful in our faces.
Joy (n.) designates nothing at all — neither an inward thing nor an outward one.
