A short version of his longer original work, this is a great book in that it tells the history of Chinese philosophy in a systematic manner. Both fortunately and unfortunately, the content is a lot easier to absorb than any Chinese text on the subject, simply because it is written in an analytical language (English) rather then a poetic and suggestive language (Chinese), (plus reference to western philosophical terms which really helps). Highly recommended for any reader who want an introductory course on the subject.
