This codex is a collection of essays and definitions designed to make atheism approachable to a wider range of people. New Atheists and Anti-Theists will find arguments which can strengthen their position. Agnostics, or those questioning their faith, hopefully can find some answers to questions they’re having, and reassurance that they are not alone. There’s even something for the hardened theist, who can find answers to common questions like “why do New Atheists proselytize”. It’s cross referenced and appended, but also as direct and comprehensive as possible, making it approachable by the novice and the expert alike. Lastly, while the essays tend to be in order of importance, the codex is not intended to be used linearly; you can follow any argument any way you want to go, building your own curriculum, as it were, at your own pace.
