Boundaries are necessary for differentiation.
- Boundaries are necessary for differentiation.
- Without a boundary, the differences diffuse.
- A boundary has two dimensions:
- 1) What is the pressure gradient?
- Do people want to join or leave the inner thing?
- 2) What is the valence of the boundary?
- How do people feel about people on the other side?
- The latter is what makes a boundary get entrenched, making it so people close to the boundary push away from it.
- Leaving a charged no-mans land, in proportion to how valent it already is.
