The purpose of this study is to read William Carlos Williams` long poem Paterson with the other`s viewpoint, especially concentrating on nature and things. By personifying the city Paterson and `Patersonizing` himself, Williams can contact all the individual concrete materials in their position. He asserts `rigor of beauty` is not a particular thing but an essential value of each thing that can be grasped by the poet`s imagination. The poet Paterson contacts with all things, through the immersion in the filthy Passaic river and by two-way interaction. And he realizes that man, nature, and things are in a symbiotic relationship. Thus, such things as the city Paterson, Garret Mountain, the Passaic River, mink, the bottle, radium and so on, go beyond their distorted aspects and recover their value. Williams stresses the active penetration between the poet and the thing by imagination, trying to understand the other`s position. Also he represents a new emphatic vista to understand the value of alienated things and recover the city.
