Review of Ultrasociety in Journal of Cognitive History 

Intro:

“Ultrasociety is written with élan and elegance, and the argument presented by the author is new and thoughtprovoking. Contrary to other scholars in the field, Turchin accentuates war as the fundamental evolutionary driver. This may sound excessively hideous and cynical to readers, but Turchin sophisticatedly and persuasively develops his argument throughout the book.”
