Art is an activity—by that I mean the activity of creation. The artist is a person engaged in the activity—in the moment of creation. We can only qualify the object itself—whether it’s a story or a poem, a sculpture or a painting or a film, etc.—as art while it is in the process of being created.
Before it is created, an object of art is mere fantasy; the artist, a thinker; the activity, an abstraction. After it is created, an object is a commodity; the artist, a bullshitter; the activity, a memory.
To those who are passive in the arts—i.e., the viewers or readers, etc.—the activity is the intention; the object, an ambiguity, something open to interpretation; the artist, a craftsman.
The act of creation—active—and the act of interpretation—passive—are distinct acts. Any theory of art that doesn’t take the distinction between the active and the passive into account is an incomplete theory.
