This is an examination of what an exchange is.
Glances in the street.
Institutions of exchange, accepted ways of behaving to make exchange easier.
What are the institutions and what should they be.
Should we be looking at computers to avoid each other“s gaze.
It”s a deep miracle that we can have knowledge in our heads about the world which is not in our heads.
It is an extra miracle than we can exchange the first miracle by making dead signs in the world.
Exchange is a kind of change. What kind of change?
