A guide to the inquiry
Start here.
Divine simplicity asks what it means for God to be the source of everything without depending on anything. Begin with the first question, or follow a path through a difficulty you already have.
Read a question as an argument.
The short answer gives you your bearings. The sections that follow develop the reasons, bring primary sources into the discussion, and face a strong objection. “What follows” identifies the conclusion and its limits. All of that material is open to read on every question page.
The method explains the distinctions used throughout. Keep the glossary nearby when a familiar word carries a more precise meaning.
The continuous route

The 25 questions form a connected inquiry. Reading in order lets the distinctions build.
