How do we know that we are connected with another? What needs to exist, for an us to be here?
How do we know that we are in-context with each other?
When this is true:
A boundary exists within which a set of coherent metaphors are in play. And we have a level of confidence that we can use these shared metaphors to play together.
Then we are here. Then we are connected. Then we have the means for our unconscious beings to communicate.
