In dealing with the relation between existence and value, the author first gives an analysis concerning the meaning of existence and value respectively, then bases his argument on the Confucian theory of human nature, and his conclusion goes on as follows: 1)value, the act of evaluation, or the "ought to be" is significant only for human being because the condition for evaluation is freedom to choose; 2)thus, the criterion of value, or the sense of good and evil, must be inside human nature; 3)this "inside" must be understood as a propensity rather than an entity; and 4)the idea of human nature as "tending toward goodness" is Confucian`s original standpoint and is competent to interprete the essence of humans.
