Chapter 16

Overview
This Chapter is about the connection between self-reference in its various guises, and self-reproducing entities e.g., computer programs or DNA molecules).  The relations between a self-reproducing entity and the mechanisms external to it which aid it in reproducing itself (e.g., a computer or proteins) are discussed - particularly the fuzziness of the distinction. How information travels between various levels of such systems is the central topic of this Chapter.
