# Part IV — What we lose

**Part page — the chapters in this part (5).**

Part Two conceded almost everything: others found the components of the model independently, described them more carefully, and in several cases measured them. This part asks what remains that is the model's own. The authors' answer fits in a sentence; defending it takes five chapters.
