The traditional titles given to each chapter are mostly an initial two or three incipits. In some cases a title may indicate a central theme of a chapter, but it is inappropriate to regard a title as a description or generalization of the content of a chapter. Chapters in the "Analects" are grouped by individual themes, but the chapters are not arranged in a way as to carry a continuous stream of thoughts or ideas. The themes of adjacent chapters are completely unrelated to each other. Central themes recur repeatedly in different chapters, sometimes in exactly the same wording and sometimes with small variations.
