Kasper.Just an emotion is not art, but when we put that emotion in a box, so that the observer has to think about it, and little by little, he will get a glimpse of what the creator wants to say, then it becomes beautifull.
Then art is enhanced and much more effective communication.
I think is it.
Dewey commented about the Greek notion of art. It's perhaps still current as when someone says, about for instance an economical car ,"this model is a work of art".Etc.So this is 'work of art' which is a way of praising something, but it's not these days a philosophical definition of what art is.
