Foundations of philosophy

The 33 Principles

Stephenson’s numbered framework for following the philosophy.

The big idea

The principles move from broad claims about intelligence and matter toward more specific ideas about living organization, transmission, and coordination. Use them as a map for reading. You do not need to memorize all 33 to begin understanding how the ideas connect.

An everyday illustration

A book’s table of contents helps you see the arrangement before studying every chapter. The numbered principles can serve a similar orienting purpose.

An original illustration to help explain the idea, not a quotation or evidence of a biological mechanism.

In the author’s words

“These are stated and numbered for convenience so that their application to things under discussion can be seen.”
