The Great Divide: Nature and Human Nature in the Old World and the New by Peter Watson

Long-lost cousins with vastly different upbringings

When Europeans first discovered the Americas, it was the meeting of two vastly different cultures, two populations that were entirely alien to one another. In his 2012 book, The Great Divide, British intellectual historian Peter Watson investigates how and why the peoples of the Old and New Worlds developed so differently. Watson makes the case that differing environmental conditions in the two hemispheres—climate, topography, flora and fauna—forged two diverging trajectories of civilization and culture. In The Great Divide, he has compiled compelling evidence to that effect into a sweeping overview of human history. Some factors that he considers are the role that natural disasters played in the creation of gods and religions, how different flora and fauna affected the rates at which agriculture and cities developed, how the use of psychotropic plants influenced cultural ideologies, and why was human sacrifice such a widespread practice in the Americas?

As I’ve come to learn from previously reading his books Ideas and The Modern Mind, Watson is a master generalist who can pull together concepts and data from a wide variety of fields in the sciences, humanities, and the arts and unify them into a remarkably cohesive whole. The Great Divide, however, is pretty much all about archeology, anthropology, and paleontology. I thought this book would have something to say about the cultures of the Old World and the New after the first transatlantic contact, but with the exception of some brief coverage of the Spanish Conquest, it is entirely concerned with events prior to 1492. Watson’s investigation begins with the dawn of humans and spends a lot of time in the Ice Age. Socrates, Buddha, and Confucius don’t show up until chapter 18, and the Spaniards don’t reach America until the 23rd and final chapter. The Great Divide is basically a comprehensive summary of world archaeology, as much as we knew in 2012. I enjoy reading about archaeology, but because I read quite a bit on that subject, a lot of this was review for me. Nevertheless, as is always the case with Watson’s books, he enriches the general narrative with plenty of interesting facts and connections that will be new and intriguing to most general readers.

If the purpose of this book is to compare and contrast the pre-1492 trajectories of the Old and New Worlds, it is not entirely successful. Watson presents a few chapters on the history of the Old World, followed by a couple chapters on the history of the New World, and back and forth, and back and forth. Only in the conclusion of the book, when recapping all the evidence presented, does Watson really take the time to make side-by-side comparisons between the two domains and draw generalizations and theories from their differences. The two hemispheres, not surprisingly, do not get equal time and consideration. It seems like the book is about two-thirds Old World and one-third New World, simply because there’s so much more pre-16th-century information available on Eurasia than there is on the Americas.

The Great Divide is an excellent synthesis of human history that draws interesting parallels and deviations between the peoples of the Eastern and Western hemispheres. This book will not, however, captivate the general reader to the same extent as Charles Mann’s excellent 1491 or perhaps Jared Diamond’s Guns, Germs, and Steel (which I haven’t read, but it was a popular bestseller). Although Watson does generate similar wow-factor by delivering insightful revelations to curious readers, The Great Divide has more of a textbook execution to it, rather than the more investigative science journalism feel of Mann’s work. Notwithstanding, if you are at all interested in the ancient history of world cultures, this book’s breadth and depth make it a must-read.

The ebook claims that an Appendix 2 is available online at the Harper Collins website, but it’s not there, and that’s really annoying.
