Art is expressive, creative, and personal. I think of art this way because that is how I feel about it, and how I interpret it in any form.
Art is, as a general qualifier, personal. It is unique to the person that produced the art.
My definition of art, and the modules definitions of art are very similar. I agree that art is transcendent of the observers personal experiences and explanations of what it means, while also relating back to human experiences, that are personal and can be explained by the average person. I think art can enlighten and intrigue people to experiences they were unaware of, or in new and unfamiliar ways, deeper ways.
Art is not always physically beautiful. Beauty can come from the emotional, intellectual, or spiritual impact of art. Art can also be brutal, it can be crude or confusing. The value put in art is not always how pleasing it is to the eye, but to be pleasing to the eye, art can also be hard to look at. It can be gruesome, or too honest. Beauty in art comes from how much someone is drawn to it, how much they relate to it in their own way. Beauty is not a consideration for me in regards to art, the context of the message in the art, from the art, is more valuable. Beauty does not determine whether or not I view something as art.
