A great introduction to philosophy in different parts of the world through the ages. Although it does not go into depth as much as, for instance, "A Companion to World Philosophies", it more than makes up for it by being highly readable.
There is a basic leitmotif that permeates Cooper's exposition of the various philosophies, and that is the attempt to relieve the tension that is created by the uniqueness of the human condition - the ability to self-reflect - which is at the same time located within the totality of nature.
The book, basically, addresses how different philosophers, at different times, have attempted to reconcile this tension.
A must-read if you're interested in philosophy in China, Japan, India, the Jewish/Islamic tradition, and the middle ages.
