Lewis Dartnell’s THE KNOWLEDGE was reviewed in the Wall Street Journal and the Times and excerpts from the book have appeared in Esquire, Time Magazine and the Io9 blog. The Wall Street Journal said, “The Knowledge is a fun read full of optimism about human ingenuity,” while the Times said, "An extraordinary achievement. With lucidity and brevity, Dartnell explains the rudiments of a civilization. It is a great read even if civilization does not collapse." Penguin published the book April 17, 2014.
