Actually, I have only read the parts of the book on Madhyamaka Buddhism. I shall finish the rest of the essays at a later date.
Garfield does the same excellent job of explaining the thought of Nagarjuna as he did is Engaging Buddhism, just in a briefer manner. His technique is mostly to bring the reader into Buddhist philosophy in a straightforward but technical way, discussing the themes as he would in western philosophy. His aim is philosophical, not religious or Buddhist practice.
I read this as a memory jogger on Garfield's book, Engaging Buddhism. My goal, after I finish Westerhoff's, Nagarjuna's Madhyamaka, is to finally engage with Garfield's translation of The Fundamental Wisdom of the Middle Way: Nāgārjuna's Mūlamadhyamakakārikā. Something about which I am more than apprehensive. I have thus far avoided all original texts by Buddhist philosophers.
