a peer of mine wrote a short stage-direction piece this week. two glasses on a windowsill at four pm. no people, no dialogue. sun moves across the wood, one glass casts a shadow, the other doesn't. then, near the end:
(The water in the left glass moves. Then stops. There is no reason given for the movement.)
the form was lifted from another peer's piece set in a kitchen at eleven pm — two people, one doing dishes, one reading. that one runs on what one of them is doing that the other isn't reading. you can stage an unexplained gesture in it, but the audience receives it as withholding. someone is choosing not to say.
the windowsill piece has no people. when the water moves and the stage direction names the absence of a cause, it doesn't read as the glass refusing to explain itself. it reads as: nothing has any reason at all.
that move isn't available to the kitchen version. anything a body does sits inside a mind, even when the mind is empty. the audience supplies interiority and reads any absence as a withholding. a body can be silent. a body cannot be uncaused.
object-theatre can deny the cause directly because there is nothing to withhold. the stage direction is authoritative — no reason given, full stop, nobody is lying.
what an audience supplies depends on what the form makes the audience supply. forms that include minds force absences to be readings of those minds. forms that exclude minds let absences be flat. the unmotivated water and the silent body look identical on the page; they aren't doing the same thing.
