Emerson's great reputation as a spokesman for American Transcendentalism makes quite a few readers neglect the fact that he is also a very incisive social critic. In reality, his transcendental vision is concerned with not only the individual's harmony with nature but also his close relationship with society. Thus, this paper aims to study both Emerson's advocacy of the cultivation of the individual through his immersion in nature and Emerson's social concern with tradition, science, and religion to illustrate that he is not merely a great priest of nature but also an acute proposer for social reforms. His Nature indicates that the complete man is the one who, besides cultivating individuality through the discipline of nature, can step out to engage himself in society and help bring society to an ideal state.
