Query: A truly important book

This is one of the more important books of recent years, persuasively dispelling the myth that non-technological societies possess an innocence and a devotion to peace that modern societies lack. Based on solid research, this book counters the popular contention that the introduction of Western values and customs tends to destroy the purported tranquility of primitive life. All students of history, particularly those inclined to view Western culture as inherently inferior to the cultures of Rousseau's "noble savages," ought to read this book. An outstanding work.
