The chapter's reasoning can be organized into five connected stages:
1. The world's origination is taken from the preceding inquiry.
2. An originated or contingent existence is held to require an originator or determiner.
3. No dependent contingent member is accepted as the independent origin of all such members.
4. The cause-of-the-collection argument and the correspondence proof address infinite regress.
5. The inquiry aims to establish an independent and unique Necessary Existent.
Key discipline: The premises about origination, dependence, and regress must be assessed separately. This reveals both the force of the classical case and the precise places at which objections arise.
