There are different methods on categorizing the aim of art. For instance, Lévi-Strauss groups art as motivated and non-motivated, each with further subcategories. Jake Shore describes art has having six aims: religious purposes, social commentary, story-telling, self-expression, beauty, and emotion. Therefore:
Progress can be classified as any development made that improves an artist's ability to achieve one of these aims.
This also highlights the dominance of personal knowledge over shared knowledge in art. This is because this kind of progress is advancement in personal knowledge, but not necessarily shared knowledge as viewers may critique an artist's decisions and suggest improvements on how they portray their message.
A theme of art that sees these kinds of disputes is beauty. This is because there is a great amount of diversity in the perceptions that viewers have of art, so one may perceive something as beautiful and one may not.
Thus, it is arguable that:
-
For example, an artist may wish to expression their emotions in more detail so that it is closer to the truth. So, if they improve in their artistic ability or their self-understanding to be able to achieve this, they have progressed.
Subjective (to the artist), but undeniably true, changes towards an subjective goal.
