This is a simple philosophical thought based upon the meaning of art.
Art is the origin of self expression and the essence of self expression. We see style and form come out in all forms out art. This is to show that it is unique to the artist and the artist must have a purpose for creating the artwork. The purpose can be as simple as: it is what I do. I create for the simple act of creating.
The image or sounds that you see and feel are the sounds and images that reside deep inside the artist. They are the expression of an idea or feeling through self.
This simple thought is how I see all art and how art has become so inclusive of a world that it contains nearly every aspect of creating and exploration of fields of thought such as mathematics and sciences.
