“For something to become a work of art, a labeling process must take place that requires three participants: an artist who produces an apt object, a client or public, and a critic or connoisseur who mediates between the artist and the public to assure them of the artness of the thing. If I make a painting, it is not sufficient for the painting to be "art" that I consider it so, nor even that you, my friend and neighbor, admire it and hang it on your wall; it must be certified as art by competent authority and exhibited in the institutionally appropriate place, a gallery or museum.”
