||The poem is a literary style that displays the esthetic sense and expresses the sentiment will by the fine and the rich rhythm's language. Developing from the “classical poem” to the “modern poem”, there is a quite big change on the style, the way of expression and the word usage of poem. But the only thing unchanged is the basic spirit “ the poem tells will”. After the western culture penetrates to the eastern world, the modern poet has had a long-term controversy in the creating-technique of “modern poem”. Due to the poem controversy, it also highlights the importance of “the modern poem” in the literary arena and the academic research. Because the importance of “modern poem” is highly valued in the poetic field and the academia, modern poets work hard to create own sky for themselves. The “Spiral Structure of the Third Nature” of Lo Men was created under this kind of situation. In addition with the “ lamp house”, they show the true knowledge, distinguished opinion and achievement of Lo Men on the “modern poem”.
The creating subject of Lo Men is quite comprehensive including war, death, space time, city, nature, selfhood and lyric. He also proposes a complete set of poetic philosophy. Basically, poetic philosophy is developed under the poetic theory coordinating to his work. This theory sums up as “Spiral Structure of the Third Nature”. The “Spiral Structure of the Third Nature” is a set of creation theory that developed by the contemplation to city life. Lo Men classified this theory by three levels----“the First Nature”, “the Second Nature” and “the Third Nature”. These three levels are affected mutually with close relationship. In order to let readers and researchers understand his creating process as well as the meaning and idea, Lo Men has spent a lot of efforts to elaborate his “Spiral Structure of the Third Nature”. It looks like the “Spiral Structure of the Third Nature” is quite complicated; but actually it tells that poem is able to create the existing world and the eternal life of “the Third Nature”. In order to keep the “Spiral Structure of the Third Nature” updated with the current trend without out-of- date, Lo Men therefore uses some western and modern creating theory and technique to bring forth the feature of combining Chinese and Western trend in his “Spiral Structure of the Third Nature”. However, because of the problem with Lo Men’s explanation and comment to some of western creating theory, it makes researchers or commentators propose different point of view to criticize him.
The reason that Lo Men defines the three levels by “ The Nature” is because he is standing at the same high altitude as the God to look at the all things on Earth. The three “ The Nature” is not the “nature” that recognized by the ordinary people, but the artificial nature. Malaysian scholar H.N. Law（侯亨能）changes the name of “The Nature” to “ The World” which is also acceptable. Lo Men constructs the theory of “Spiral Structure of the Third Nature” by approaching the “the Second Nature” to “the First Nature” to make the human beings unable to release under the pressure of “the desire for material welfare” and “the sexual desire”. Therefore, Lo Men has to use poem and art as activator to combine “the First Nature” and “the Second Nature”, then gets into the beautiful eternal world of “the Third Nature” finally. For this reason, Lo Men specially pays high attention to the environment of city and nature that human beings live.
Based on the theory of “Spiral Structure of the Third Nature”, Lo Men uses the “City-Poem” and “Nature-Poem” as the subject in the modern poem. Apparently, this creating-theory has close relationship with these two subjects. Based on this statement, I take the “City-Poem” and “Nature-Poem” as the subject of my research and study the performance of Lo Men’s in the modern poetry on the basis of “Spiral Structure of the Third Nature”.
