Abstract: In addition to the inner morality, the core value of Confucianism has the dimension of external enterprise. Confucius’ valuation of Guan Zhong as ren has explained it. After the Warring States period, Confucianism gradually turned inward, and to some extent gave up the pursuit of extroversion. Confucius and Mencius both had experience in politics, and the original Confucianism also attached great importance to the country's wealth and armament while promoting education. The world peace in Great Learning has material foundation and institutional support. The inherent moral interpretation of Confucianism has always neglected the dimension of external enterprise, so that there is a prejudice of "moralism". Ren cannot retreat to inner morality, and the outer dimension of ren must be explored when appropriate.

Key words: original Confucianism, ren, cause, external dimension
