Aesthetics are not about decorative ability, but about a person's underlying filtering system. Because it can:

First, judge superiority or inferiority. It is a person's overall discernment of language, behavior, relationships, postures, and interests.
Second, replace morality. Many people do not do bad things not necessarily because of deep moral training, but because they instinctively feel "too ugly."
Third, the source of "taste." The so-called good taste is not about being rich, cultured, or educated, but about a person not allowing themselves to fall into a certain low-level state.
Therefore, the high-level aspect of aesthetics lies in the fact that it does not tell you what is right, but makes you instinctively stay away from those ugly, despicable, and embarrassing things.
