Short Paper Inyoung Park Opinions vary on the relationship between humans and the world and the attitudes that humans should have in life. Tao's <Substance, Shadow, and Spirit> present these different perspectives. The biggest feature of this poem is that it defines human characteristics by dividing them into three categories: Substance, Shadow, and Spirit, and describes the attitudes that humans should have for life from the standpoint of each characteristics. Substance and Shadow have an argument, and Spirit mediates it and makes a solution. The main topic that the three characteristics argue is related to human mortality. The poem is largely divided into three parts: Substance to Shadow, Shadow to Substance, and Spirit's intervention. Substance refers to 'body', or the material characteristic of humans. He separates the nature from humans. Unlike nature, which has immortal or constant cycles, humans are the most sentient beings in the world. However there is also no cycle of going and coming back. Instead, it "is present in the world today, then leaves abruptly, to return no more." The phrase "he has no way to change" reveals the acceptance and futility of human existence and mortality. This reveals the thoughts of Substance, thinking human life and death are vain and ephemeral. The meaning of wine, which appears out of the blue in the last phrase that Substance asks for Shadow, is not well revealed from the outside. However, according to the context with the previous phrase, it is a symbol of joy, a mechanism that makes him forget the pain, and affirms his present life. Unlike life of heaven, earth, nature being permanent, human life is short, so the idea of enjoying life as much as possible while alive is revealed by telling Substance not to reject wine. On the other hand, Shadow symbolizes the desire to leave a name after death in the future. Shadow is inseparable from Substance as shown in line four, and it is impossible to separate them. While Substance values physical pleasure, Shadow questions, "Is this really the right thing to do?" He has no choice but to follow what Substance does, but at the same time, he constantly questions the actions' value and argues that there is something more important than physical pleasure. Rather than the pleasure that Substance claims is the most important thing, Shadow argues that it is more important to leave the name to the future generation even after death by doing good deeds. Drinking wine can make worries disappear, but it's a sleazy way compared to making great achievements. Therefore, Shadow advises Substance to do good deeds for their posthumous reputation. When two egos collide and cause conflict within one being (a human), Spirit mediates the two in a tone that seems to soothe them. In the beginning, Spirit mentions the complementarity of the three egos. They have different forms and different ideas, but they eventually integrate into one being and are indivisible and dependent on each other. He then re-emphasizes the equal finiteness of human life, referring to those who have been great in their lives but have already died. Since everyone dies regardless of age or wisdom, it can be considered that Spirit's opinion is implied to be cautious of being overly obsessed with life. Then he directly refutes Substance's argument who values physical pleasure, such as drinking wine, and is concerned about it shortening the lifespan of human. He also refutes Shadow's claim who emphasizes to leave his name in later generations, and talks about the ephemerality of human life once again by asking who will praise him (after he has already died and disappeared). Ultimately, he recommends that everything be accepted naturally because there is nothing to be happy about life, and there is nothing to be sad about death. The poem ends by recommending that people enjoy life naturally while conforming to death, and that being obsessed with life and thinking too much about life and death is rather damaging. In the preface to the poem, Tao criticizes those who "clinging tenaciously to life" as "great delusion." He then reveals the background of his writing the poem and encourages to think about it together. It is presumed that the background of writing this poem was to express Tao's own concerns about the view of life poetically. In conclusion, Tao divided human life into three subjects and expressed different life attitudes and physiognomy of each subject in contrast, and placed the most importance on Spirit's attitude among those three. The opinion described from the perspective of Spirit seems to be what Tao was ultimately trying to say. Although they have such different views of life, they are complementary to each other because they eventually combine to form one being. It is a poem that reveals Tao's own concerns and inner conflicts about what kind of attitude should people have about life.
