Palombo points out that it is not essential for the reader to go through all of the chapters on computer models of self-sustaining and self-modifying systems to get the gist of his ideas and use them clinically. The concepts presented in these chapters are complex and require frequent rereadings and cogitation. However, reading these chapters is important not only as a strenuous mental exercise, which is good for the brain, but because they describe recent developments in post-Darwinian, modern evolutionary thinking. Evolution is often a glacial process, but it need not be, as documented in Jonathan Weiner’s exquisite volume, The Beak of the Finch(3), which Palombo refers to in this book and integrates into his ideas.
