I wonder. Do we all agree that art is an attempt at communication?
Communication, of course, requires a sender and a receiver, as @Nullo points out. Then, what is the significance of the sender’s intent and the receiver’s perception? Some people have asked if the sender intended to send some information (say that this is art), but the receiver doesn’t understand it as art, do we have any communication going on here? Does communication require exact understanding?
Anyway, if the creator of the art is paramount, than anything the creator considers art must be art, even if no one else perceives it to be art. Similarly, if the perceiver of art is paramount, than many things might be considered art where there was no intent to make art.
I just took a look around my office. Phone, pencils, plastic silverware, filing cabinet, lamps, jewel cases, clock, soda bottle, chair, etc, etc, etc. I do not see a single thing that someone did not put in an effort to make look more appealing—an apparent effort to communicate both aesthetics and an idea of how the thing should be used. It’s all art, to me. I can appreciate the aesthetic elements in all of it. I can appreciate the process by which it is made.
Receivers may or may not perceive the information the sender sends very accurately. They may perceive messages where there is no apparent sender to send the message.
Senders may also have no clue about how to communicate. If no one understands the message, or if they understand the message in some way antithetical to the intent of the message, then how can we be talking about art?
I don’t think there is any definition of art that you can get much agreement about in any small group of people. I think in the larger community, there are probably different camps, with different ideas about what art is.
To a large extent, I think, it is these social groups consensus that determines what art is. There are different groups of people who determine what goes in museums, and what fetches high prices, and what belongs in galleries and what gets sold at roadside stands and what is made purely for domestic consumption or for decoration or any other attempt to make things more aesthetically pleasing to perceivers.
There is probably some consensus about what art is that is shared between all these groups, but there is probably a lot more that is not shared. The definition of art is not something you can gather a large consensus about. It’s also kind of irrelevant, except as a starter for cocktail party conversation where no one particularly cares what anyone else says.
For me, art is a way of perceiving. It is about looking for underlying meaning—the whys and wherefores of an act by an apparent creator. Except it really doesn’t matter if there is a creator, nor, if there is a creator, what the creator intended. I see what I see, and if I see art, then it’s art.
Sometimes I am interested in the intent of the artist. Other times I’m more interested in what I find there. When I talk to others about art, I urge them to see what they see and not to try to guess what the artist intended. The artist isn’t here. All that is here is the artifact, which must, then, speak for itself.
I have seen this discussion break up a group of friends faster than being run over by a runaway train. For some reason, it seems to generate powerful feelings by people who feel a certain righteousness in their point of view. Let’s look at another little example. If I intend no condescension in a comment, yet someone else feels I am condescending, who is right? Can we both be right? What if I intended no condescension, yet, when someone reads the comment, they feel like they are being condescended to and they point it out, and I decide that yes, it was condescension. Furthermore, it was well-deserved condescension. What then? Did it change from non-condescension to condescension? If so, it makes for a really easy way to push someone else’s buttons. If they let those buttons be pushed.
