its purpose

"A beautiful design must EXPRESS ORDER. It must also POSSESS QUALITY. It must be SKILLFULLY made from appropriate materials. It must also be USEFUL and PRACTICAL, based on the function it serves. Beauty confirms our ideas of what is RIGHT, PROPER, and fit for the use of human beings.

[...] The purpose of beauty in a design is TO ENRICH THE VIEWER, WHO IS ENLARGED BY THE EXPERIENCE. Beauty is thus a vital function of architecture.

A beautiful design alone, as George Nelson has said, cannot transform a dark, unhappy life into a joyful one; only the person living the life can do that. The purpose of a beautiful design is TO ENRICH LIFE."
-Paul Speiregen & Lester Wertheimer, Programming, Planning & Practice, p.83

Everything exists for a reason. All artwork pieces should have its purpose, and its function to serve. How can something (or even someone) be beautiful when there is no meaning to it?
Then we ask ourselves: "are the reasons and purposes for our works valid enough for them to be existed, what/who do they serve?"
