Williams` poetry at the time of American literary revolution has been well known as a leading lamp for modern poetic formation with objectivism. At the 1920`s, William Carlos Williams, Louis Zukofsky, and a number of young poets gathered under the name of objectivism to lay stepping stones for the new horizon of modern poetry. Williams wrote many of his poems spontaneously, but he also liked to keep normal patterns of poetic theory. He thought that the artist should have aesthetic principles so that he could understand how to organize a satisfactory poem. Though he remained true to the basic principles of imagism throughout his career, Williams grew dissatisfied with the limitations of the movement even at its early stage. To find out truth among the local material around him everyday, his poetry at early period of his literary career went beyond the tenet of imagism. It was not until his middle age that he adopted a new poetic theory to activate his new poetic practices. When Zulpfsky explained his principles of objectivism, based upon poems of his contemporaries, he would make the most of Williams. It signifies that those principles are still useful to understand Williams` poetic diction. Reading his poems; "Young Sycamore", "An Early Martyr," "The Yachts," "The Source", and "The Sun," it has been finally recognized that all the themes are related with things around him. Thus his poetic techniques definitely evolved to provide a picture image for every common reader. It is due to his theoretical aptitude that he denied all the possible exposition of his idea or suggestion in the text of his poetry.
