Author's Note This book consists of excerpts from earlier work together with considerable new material. The excerpts are printed in regular typeface, while new commentaries are printed in italics [I'm likely to put underscores around italics _like this_ if I encounter them]. The introduction and chapters four, eight, and ten are new material but are in regular type because in each case they constitute a full chapter. The excerpts weave together material from various parts of their respective books, and have been edited for clarity as well as for gender inclusiveness. I provide endnotes for new commentaries, while citations for excerpts can be found in the original work. In the use of Chinese words, I have changed the original Wade-Giles romanization to contemporary Pinyin.
