In process

hanging garden of Babylon, historyDavid Tollen’s new book tells the histories behind today’s great issues. It’s a “reader’s digest” for the vital ideas of anthropology and world history – with a user-friendly voice and a rare breadth of topics. Those topics include the origins and role of “races,” humanity’s 50,000-year management of the environment, the sources of Western power, the deaths of democracies, our species’ unusual war with microorganisms, and the myths and realities of conspiracies. Each of the fifteen chapters covers one topic — in just eight to eighteen pages. (See below for the table of contents.)

Origin Stories‘ genre includes works like Harari’s Sapiens and Diamond’s Guns, Germs and Steel. But it’s shorter and simpler than those and similar books, so it will serve a broader audience.


David Tollen has succeeded in multiple roles by explaining very complex topics in simple, user-friendly language. He is a best-selling and award-winning author, expert witness, attorney, sought-after speaker, and instructor at U.C. Berkeley Law School.

David wrote The Tech Contracts Handbook, which has for years ranked as the #1 bestseller on Amazon from ABA Publishing. He also wrote The Jericho River, a multiple-award-winning YA novel that uses fantasy to teach world history. And he writes this blog.

David teaches IT contracts at U.C. Berkeley Law School. And he works as a lawyer, legal trainer, and expert witness at companies he founded. He also serves on the board of advisors for World History Encyclopedia. David has degrees from Harvard Law School and Cambridge University, as well as a B.A. in history from U.C. Berkeley.
