Commentaries on the I Ching

by Ralph H. Abraham

During the second half of 1971, while living in Amsterdam, I began a book of commentaries on the I Ching. The project was discontinued in early 1972 due to professional duties in Amsterdam and Paris. The extant parts of the manuscript are presented here for what they are worth, and perhaps the project will be resumed one day.

The book was to be in three parts. Only the introduction and first three chapters of Part I were completed. Here are the extant portions, comprising a journalistic review of the history of the I Ching. The Figures are missing, and will be posted later.
