What is an object? A set of part becomes a unity when they act together (i.e.., they produce a joint effect). This is a consequence of the Eleatic principle that existing is producing effects. The room exists as a whole because, for a moment, it acts as a whole by means of our body
Our body brings into existence whole worlds (whole rooms, whole objects) because they can act as a whole. The unity is not between those parts, is in what happens afterwards and elsewhere (the joint effect in one’s body).
