The book is quite long (700+ pages), so the discussion will be held on Dec. 15 to give us plenty of time to read it.

From Amazon:
"War! What is it good for? Absolutely nothing," says the famous song—but archaeology, history, and biology show that war in fact has been good for something. Surprising as it sounds, war has made humanity safer and richer.

Renowned historian and archaeologist Ian Morris tells the gruesome, gripping story of 15,000 years of war, going beyond the battles and brutality to reveal what war has really done to and for the world. Stone Age people stood a 1-in-10 chance of dying violently. In the 20th century, by contrast—despite two world wars—fewer than 1 in 100 died violently. The explanation: Wa has created bigger, more complex societies, ruled by governments that have stamped out internal violence. Strangely enough, killing has made the world safer, and the safety it has produced has allowed people to make the world richer too.
