Almost every poetry in these days is lyric poetry. It subjectifies and internalizes the external world. Poetic lyricism is formed in the process of subjectifying and internalizing poetic objects. Poetry categorization still exists. However, few theories and discussions on poetry classification focus on the essence of the lyric poetry, lyricism. Such theories as I.A.Richards' 'Poetry of exclusion', 'Poetry of inclusion', Ezra Pound's 'Melopoeia', 'Phanopoeia', 'Logopoeia', John Ccrowe Ransom's 'Platonic poetry', 'Physical poetry', 'Metaphysical poetry', Robert penn Warren's 'pure poetry', 'impure poetry' etc, are necessary to analyze poetry and construe its characteristics. But these are so simple that remain superficial. Poetry can be distinguished into six patterns on the basis of Roman Jokobson' 'Six Communication Functions' - emotional lyric, information lyric, directive lyric, phatic lyric, meta-linguistic lyric, esthetic lyric. This tool is useful in grasping linguistic characteristics and the category of symbolic meanings by text analysis. However, it is required to the essential and concrete categorization of lyric poetry that focusing on the lyric self's attitude toward the world. Besides this is the capable way that the gap between theory and practice get narrow. In this article, hinted at Wolfgang Kaiser's three lyricism theories, the lyric attitude to the world could be divided into 4 patterns-opposition, adaptation, assimilation, rejection. Lyric poetry also could be categorized in accordance with these patterns as follows: First, 'Poetry of opposition' features conflict between the world and the self. Lyric self, who fails in adapting him/herself mentally to the conditions or things in real world, assumes a confrontative attitude against it or despairs of it. Within his/her internalized lyric dicourse, lyric self resists the real world by criticizing, satirizing, struggling against it. Second, 'Poetry of adaptation' is characterized by interacting with the real world and the lyric self rather than opposing each other. To adjust him/herself to the real world, he/she seeks for the objects for identification, rationalization and scapegoating. It is the poetry of boundary in which a lyric self is eager to overcome conflict by compromising with the world but fail to integrate into tionit. It also describes the solace or awakening he/she takes from relations with the world. Third, 'Poetry of assimilation' expresses absolute integration and internalization between the world and the lyric self. Subjectification of the world, that is, 'internalization of the world' is made up in the narrowest meaning in this pattern. There is no antagonism between the world and the self, therefore no adaptation process. It describes the experience of perfect unity of them beyond conflict. Fourth, 'Poetry of Rejection' is the poetry that never gives meanings on the real world and the physical objects. It denies or neglects the established logic and authority. Denial of realistic meaning and convention makes its language dispense the practical function of meaning transfer. A lyric self cites the language of meaning destruction or suffers from the illusion isolated from reality in this pattern. The four patterns above in this article not only focus on the essence of lyric poetry but also could be applied to all forms of poetry.
