Fundamentals of Ethical Teaching
As has been said in the Introduction, Ch’eng I was essentially an ethical teacher. His ethical thought was built on the basis of his metaphysical concepts and his ideas about nature, history and man. But he was interested in these concepts and ideas only in so far as they had a bearing upon his ethical teaching. He was never interested in any intellectual pursuit for its own sake. All studies and writings must be done with the sole purpose of understanding moral truth and through it the achievement of perfect manhood, or else everything is a waste of time. In this, Ch’eng I was acting the part of a typical Confucian. It was because of this that though he was an ethical teacher, he was not a teacher of “Ethics” in the modern sense of the term. He had no ethics; he had only ethical teaching.
