Scene
We, not I; on a scene, not in a mind.
Every scene, every event, is modeled on, and an iteration of, the Originary Scene/Event. Once the Originary Scene "works" and is iterated on such that Linguistic Presence is able to extend over nonritual communication within the community, the size of the group involved in the scene can become arbitrarily large (although always in a Centered Ordinality).
If we ask, how do we determine the boundaries of a scene and the end of an event, the only answer can be, upon another scene, in another event. A scene is composed, or, an existing scene is adapted, so as to concentrate focus on the center—it’s easy to think of examples, such as ritual scenes, but also theaters and lecture halls. To identify the boundaries of the scene is to construct another scene within or surrounding that scene.
