There is a universal beauty. Generally, people have a natural attraction to proportionality. That is, if something fits well with its surroundings, or its “appropriate” to be in its position, then it can be considered beautiful. One example is the Marquardt Mast:
A well proportioned is more “attractive” in people’s eyes.
However, beauty is not a measurable quality. If there is a standard for beauty, then the beauty in a farmer’s eyes will be no difference from the beauty in an artist’s eyes. Relate back to the truth and good chapter, it is not right to just consider about the appearance. Beauty should make connections, evoke feelings, and bring back memories. It is something mentally, not physically. Therefore, everyone have their own way of perceiving beauty. Some people loves nature, so there is the beauty of Sublime:
Others may like to find beauty in normal, or even ugly things. This idea is called Wabi-sabi:
Thus, great artworks are always beautiful. If a person thinks a broken bowl is beautiful, then the broken bowl is an art piece in his eyes. When an artist is creating art, he must be creating something he considers beautiful. As a result, he will spend all his effort in his work of beauty. What the audience see is not only his art piece, it is the combination of his mind and feelings.
