let me know how this hits you
i'm starting to think about the person-who-feels-something as the "subject" of art. i've heard it used in not this way before. but i have been looking for a while for a Generic term to use in place of "player" which can be applied to other art forms -- the one who is there with the work engaging with it.
"subject," to me, feels perfect. the subject is the one who actually matters. the subject acts and feels. the player of a game is the subject.
