After the 17th century, the poetic style of the Joseon period started to he changed into Song’s poetic style. The Song's poetic style of this time was different form that of the early Joseon. The people leading this change were members of Sanlim of Noron who were active in the province of Guengi, including Kimchanghyeoh. They were beyond the Confucian thought that poetry must be written from the manifestation of the human nature. They insisted that poets should describe the nature. people, and customs around them just as they were. This was a Jinsi(Real Poetry’）movement.
The change of a poetic style was a change of die world view as we)) as the poetic world. Considering poetry were a literary art of every writer at that time, this poetic change must have influenced not only literary poets but also moralists.
I named the change of the poetic style after the 17th century 'realistic ordinariness and finding-self. This study scrutinized the moralists’ poetry in Nakron school of Noron, such as those of Doam Yi, Jae(1680-1746), Miho Kim,Weon-Haeng( 1702-1720), Guenjae Bak, Yun-Weon(1734-1799). and Maesan Hong, Jik-Pil(1776-1852) who succeeded Kimchanghyeob in order to examine the matter of 'ordinariness in the Joseon period after the 17th century.
Doam Yi, Jae's poems sharply captured trivial things in ordinary life. While moralists* poems focused on ideology and its meaning had been too heavy and profound, his poems were cheerful and vigorous, which resulted from his ability to express poetic meanings through the detailed descriptions of ordinary life.
Miho Gim, Weon-Haeng expressed what he had experienced realistically enough for his poems to he called the poetic record of ordinary life. Whether his experience is in or out of ordinary life, he contained it in his poems as if he had recorded it. So, many of his poems are related to one another, and sometimes, their meanings can be captured only in the relation between them.
The poems of Guenjae Bak, Yun-Weon and Maesan Hong, Jik-pil were so prosaic that they seemed to turn their proses into verse. As it were, their poems were more implicit and less lyrical. Besides, they had strong tendency to pursue argumentative and explanatory meanings.
As a whole, the later poets described ordinary life heavily and the poetic mood disappeared, as their poetic tendency had been handed clown from Yi, Jae to Hong, Jik-Pil, The later poetry were more argumentative and more prosaic than the earlier poetry. As it were, the earlier poets contained ordinariness in their poems, while the later poets contained it in their proses.
