Of his self-education, which continued through life, he gives the following concise account: "At fifteen I entered on a life of study; at thirty I took my stand as a scholar; at forty my opinions were fixed; at fifty I knew how to judge and select; at sixty I never relapsed into a known fault; at seventy I could follow my inclinations without going wrong." Note how each stage marks an advance towards moral excellence. Mark also that this passage gives an outline of self-discipline. It says nothing of his books or of his work as a statesman and a reformer. He is said to have had, first and last, three thousand disciples. Those longest under instruction numbered twelve. They studied, not with lectures and textbooks, as in modern schools, but by following his footsteps and taking the impress of his character, much as Peter and John followed the steps and studied the life of Christ. Some of them followed Confucius when, bent on effecting a political as well as an ethical reform, he travelled from court to court among the petty principalities. They have placed it on record that once, when exposed to great peril, he comforted them by saying, "If Heaven has made me the depositary of these teachings, what can my enemies do against [Page 91] me?" Nobly conscious of a more than human mission, so pure were his teachings that, though he taught morals, not religion, he might fairly, with Socrates, be allowed to claim a sort of inspiration. The one God, of whom he knew little, he called Heaven, and he always spoke of Heaven with the profoundest reverence. When neglected or misunderstood he consoled himself by saying, "Heaven knows me." During a serious illness a disciple inquired if he should pray for him, meaning the making of offerings at some temple. Confucius answered, "I have long prayed," or "I have long been in the habit of praying."
