The recently unearthed bamboo slips of "Kongzi Shilun" (Confucius on Poetry) add much to our knowledge of Confucius' great contribution to the teaching of poetry in ancient China. In this paper, I will focus only on the philosophy and wisdom that seem very essential in Confucius' teaching of poetry and in his comments on poems. We can find Confucius' poetic wisdom in his comments on different kinds of poetry and individual poems, in the way he organized his teaching on the "Shijing", especially in his vision of affectivity as the primordial mode of human existence and the function of poetry in both self-cultivation and public life. We will also touch upon the hermeneutic issues of how to interpret the meaning of poetry. This paper will end up with Confucius' open attitude toward the unknown dimension in the poetic wisdom, that there is something unfathomable in the wisdom itself that makes the quest for it an unending process.
