William Carlos Williams ha recently come to be recognized as one of the important American poets. His works registers a change in perceptibility which puts him beyond the romantic tradition of English poetry. There is a significant relation between his ideologies and modern philosophy. Williams` assumptions about poetry and human existence are a unique type of a new horizon. His presuppositions and the way they are implicit in each of his poems can only be recognizable in his literary universe which can not possibly understood by any part of his works. The poet says that no symbolism is acceptable. The avoidance of symbolism in Williams` poetry provides more meaning beyond any symbolism. The things in his poetry stand lonely but side by side in the world, "here and now." In his poetry things of this world stand to show themselves what they are in reality, while in the romantic tradition, things in one way or another stand for any other things of the distant place. Like the red wheelbarrow, or the young sycamore and the sea-trout in the poems by Williams, the red wheelbarrow means nothing but just the wheelbarrow, which carries no particular meaning except the thing itself. A reader, looking at the red wheelbarrow, may interpret the red wheelbarrow with his particular view so unique that he could attach the meaning to it. It might be at the similar occasion that we often have different meaning in our mind, looking at the moon. In assuming such a mode of imaginative process, his work joins modern arts in which connects the fact of immediate experience. And the new technique discovered in Williams` poems may be identified in painters from Ce`zanne through cubism to abstract expressionism. What we can come across in his poetry may be traced in the preassumption of Derrida. His poetry attempts to establish his poetic diction as the sphere of a `dream language` with its total meaning.
