The Twenty Tenets
"Chapter 2 outlines "twenty tenets" that are common to evolving or growing systems wherever we find them. Many people counted them up and didn't get twenty, and they wanted to know if they had missed something. This simply depends on what you count as a tenet. I give twelve numbered tenets. Number 2 contains four tenets, and number 12 contains five. That's nineteen altogether. Throughout the book, I give three additions. That's twenty-two. But one or two of the tenets are not really characteristics, just simple word definitions (e.g., tenet 7 and possibly 9). So that leaves around twenty actual tenets, or actual characteristics of evolution. But there is nothing sacred about the number twenty; these are just some of the more noticeable trends, tropisms, or tendencies of evolution." (from the preface to the second edition of SES)
