I had a bit of time over the holidays so I read two new massive tomes on warfare, Gat's and one by Max Boot. Gat's stunningly comprehensive work is so good that it manages to make other 500+ page books seem positively lightweight and journalistic in comparison. This treatment of the history of war and warfare, or 'human belligerency' as Gat puts it, would overwhelm the non-specialist (it clocks in at about 820 pages), if it weren't for the author's ability to synthesize material, sum up scholarship and, last but not least, write some of the clearest and most lucid prose I've seen in the social sciences in ages. He makes forays into evolutionary theory, state formation, antiquity, technology and the rise of science, prehistory, the transition to agriculture, democratic peace theory, etc. The chapter on tribal warfare (in Agraria and Pastoralia, as Gat puts it) is -- as the saying has it -- worth the price of admission alone. His careful demolition of radical Rousseauist idealism is equally fascinating, but he is no simplistic, knee-jerk Hobbesian.
Gat is philosophically astute as well as deep; he knows history as well as theory; and he even treats, if briefly, the question of the causes of war. Above all, the book is animated by his personality: one can surmise that, yes, he's quite intellectual, but his is a mind that is always probing, curious and interesting. (There's a picture of the author on the back flap. He is youngish but he has bags under his eyes. He must read and write around the clock. I for one am grateful.) This is my book of the year.
