This edition goes beyond others that largely leave readers to their own devices in understanding this cryptic work, by providing an entree into the text that parallels the traditional Chinese way of approaching it: alongside Slingerland's exquisite rendering of the work are his translations of a selection of classic Chinese commentaries that shed light on difficult passages, provide historical and cultural context, and invite the reader to ponder a range of interpretations. The ideal student edition, this volume also includes a general introduction, notes, multiple appendices -- including a glossary of technical terms, references to modern Western scholarship that point the way for further study, and an annotated bibliography.
