The nature of beauty. High and low art. Indeed, I do think ethics interfaces with art here (although NB that “beauty” and “good art“ are not synonyms on my account; nor “high art” and “good art”, nor “high art” and the “nobler purposes” to which art can be put that I mentioned earlier). — Pfhorrest
What I mean is that if there really is such a thing as a
real, objective aesthetic standard, then, by nature, the standard is ethical. It's important to constantly remember that artistic expression is deeply human and deeply connected to the human experience. From my view, I have no problem with someone making arguments that there
is no such thing as an aesthetic standard, at least in theory. I would almost rather consider those arguments than those that I'm about to describe: If you're going to hint at the existence of a real standard, flirt with it, but never commit...you can't do that; you have to go all the way. You (I'm saying this broadly) can't get away with a vague notion that art and ethics are connected; that beauty and goodness are connected. I mean, I guess you can if you honestly take a sort of agnostic approach (figuratively speaking) in the sense of, "there has to be an aesthetic standard, but I don't understand". Which is probably the position closest to mine anyway. But if so, you have to acknowledge your own lack of understanding. I don't know if that makes sense, this is just off the top of my head.
I agree with you on pretty much everything else you mentioned; again, the above paragraph is just my typical word vomit; feel free to ask questions. But I have a quick note on this:
Circling back again to rhetoric, as the archetypical medium, for illustration: an argument that successfully persuades someone to believe something false or to intend something bad is thereby objectively bad rhetoric, even if the speaker meant his words to do so and so would subjectively consider his rhetoric good for its success, because by objective standards false things are not to be believed and bad things are not to be intended and so rhetoric is not meant, by those standards, to persuade people to do so, and in succeeding at doing what it is not meant to do, that rhetoric thereby fails at doing what it is meant to do, and is thereby bad rhetoric. — Pfhorrest
I think it's fine to compare rhetoric and art and notice similarities in delivery and interpretation of the two, but I don't think it's correct to lump them together (which I'm not sure if you're doing or not, but I'm not assuming you are. Just making a remark here). Rhetoric clearly functions within philosophy, as a way to potentially deliver information (ideas) in a way that sort of meets the audience where they are, rather than requiring intense logical engagement with complex information. Art is nothing like that. To me, an important aspect of art is a sort of apophatic character; art, at it's best, can sometimes be like that annoying kid in grade school (or that annoying kid in philosophy 101 in college) who questions everything, and is contrary all the time. Art hates being cornered or defined. Just by nature, when you attempt to find a nice box for art, it makes sure to not fit.
