Neil deGrasse Tyson and Avis Lang have written a very depressing book on how warfare and states' pursuit of dominance have become increasingly intertwined with scientific pursuits. Accessory to War: The Unspoken Alliance between Astrophysics and the Military covers developments from early modern Europe to our time. While the book is informative and well-organized, it fails to answer or even address the biggest question facing the scientific enterprise for which Dr. Tyson has become its most public advocate: why is humanity not acting on the knowledge the scientific enterprise has produced in order to create a sustainable, just human society?
