Hence the former kings, on occasions of great sorrow, had their rules according to which they expressed their grief; and on occasions of great happiness, they had their rules by which they expressed their pleasure. The manifestations, whether of grief or joy, were all bounded by the limits of these rules. In music the sages found pleasure, and (saw that) it could be used to make the hearts of the people good. Because of the deep influence which it exerts on a man, and the change which it produces in manners and customs, the ancient kings appointed it as one of the subjects of instruction. |
