Cosmos Chapter 7 - From Myth to Order in the Backbone of Night

This is part 7 of a 13-part reading of Carl Sagan’s Cosmos. The scope is Chapter 7, The Backbone of Night. The public note does not reproduce the source text. It uses chapter titles and short conceptual anchors to build summary, interpretation, and application.

Argument in one paragraph:

Cosmos names not only the universe, but a disciplined trust that nature can be understood. This chapter is read here as a transformative summary rather than a substitute for the book. Its main claim is that science begins from the bold assumption that the world is intelligible.
