OTOH, while we need to point to something more specific, we should also look up for a definition that is broad enough as to describe what is common to Rodin’s sculptures and to Altamira’s cave paintings. I suggest that essential elements of art are:
1) It is man-made
2) It involves the free use of imagination, even if trying to reproduce or imitate something else
3) It is always concerned with form and composition, looking for the unity of a single work.
4) It is always concerned with technique, which involves selection and articulation of materials in the medium and tools used.
5) It is made to be contemplated, to provide an experience to observers, being that experience one of pleasure or enjoyment, either sensorial or both sensorial and intellectual.
I actually want something like this to be right, but you know, contemporary aestheticians are going to have a field day with this, and I am not saying I disagree, but just that art has become so indeterminate, and nobody knows, or wants to know, what it is, because there is no limit one can impose on its nature, and this is because art has its ground not in the institutions of the past, but in experience itself. It's like trying to define economics: It's easy to talk about exchange of goods, the way money works, and so on, but note how everything you can say rests with other things. What is money if not use value of perhaps understood as a labor theory of value, or is there such a thing as intrinsic value, and if there is no value, there is no economics, so economics has its analysis in value, and value is in exchanges in every dealing we can imagine, and so all dealings are essentially economical ones in nature. I mean, to say what economics IS in so connected to all things, one can hardly find a boundary. Art is like this. Say it must involve the use of free imagination, as you do above, and one asks, what is the imagination and how is this the supposed to by in the making of art exclusively? The response is that is clearly not exclusively in the category of art that one finds imagination. But then, If one is using the imagination to conceive of a new lawn mower or dental procedure, how is it that this stands outside of art? Well, it does and it doesn't.
Or what if I have an aesthetic response to something that is not human made? Imagine, someone constructs a work of art that looks exactly like real driftwood, and I see it and believe it is just a bit natural rubbish taken out of a river. Then I am told, no this is a work of hyperrealism in 3D. Now it's art? There is an intractable ambiguity here, and philosophers try to deal with it. Is art in the observer's possible responses, of the artist's? Either way, are these not the same thing, the observer, after all, belongs to a culture and it is here one finds possiblities for judgment (this is what Heidegger argues).
There's a reason art is so ridiculous these days. It's because it is one of the most "open" concepts there is. Appreciation is SO wrapped up in criticism and interpretation, unlike economics which sort of just evolves. Art has criticism in its very nature, like philosophy, and so the banana is just an inevitability.
Isn't this where everything is headed: art doesn't know what it is because nothing like this "knowing" is possible any more. Post modern culture is entirely up in the air in terms of its social concepts, the kinds of things that in the past seemed as if there was a foundation are now int he air. It is freedom that is responsible, and long as freedom dominates a culture's social phenomena, there will always be the question, the piety of thought, Heidegger calls it---which is ironic because Heidegger is a social conservative (Jordan Peterson, the Canadian psychologist who rails against lgbtq and the moral ambiguities it raises is a Heideggerian). As long as a society is free to reconceive itself, its art will be an open concept, as will its ideas about gender identity, music, marriage, family, and so on.
