The Book of Odes
Anyone who’s read any the Confucian canon’s Four Books will have heard much of the Book of Odes. Confucius and Mencius discuss it and reference it constantly, and Confucius even told his son, “If you do not study the Odes you will not be fit to converse with.” He explains why in another chapter that I’ve quoted and discussed previously, “My young friends, why do you not study the Odes? They will stimulate your emotions, broaden your observation, enlarge your fellowship, and express your grievances.
