This paper aims to explore the Weltanschauung of the early Confucianism appeared in the Doctrine of the Mean (Chung yung) through the concept of freedom. More specifically, this study will deal with the viewpoint of the Doctrine of the Mean on the nature of person and the world, and explore how the conception, freedom, can be applicable to early Confucian world so that it can afford some reflections on the concept of freedom and understanding of the “anthropocosmic vision” of early Confucianism. For this work, we should first ask whether it is possible to directly apply the concept of individualistic freedom to the thought of the Doctrine of the Mean. So long as we stick to the negative definition of freedom as our tool in studying early Confucianism, it is quite doubtful that we can find any appropriate equivalent concept in it. Rather than directly laying the concept of freedom on the Doctrine of the Mean, it would be more helpful for our study to begin with the examination of the individualism, one of the most significant elements underlying the concept of freedom, in the broad context of early Confucianism from which the thought of the Doctrine of the Mean was evolved.
