Freedom, public’s well-fare, science and religion are some of the topics which Jonathan Swift tried to deal with in most of his writings. In addition to that Swift was adroit in creating bizarre characters, Gulliver, Bickerstaff, Drapier to name just a few. In this article the researcher has tried to analyze the most famous among them-Gulliver. Gulliver is a character with different roles. In Gulliver’s Travels, Gulliver plays four major roles. In each of them Swift conveys his criteria regarding the above mentioned topics to the reader. Language is Swift’s mightiest weapon in his works. The role of language has been dealt with in this article. Another clash which exists in Gulliver’s Travels is the clash of modernity and the classics and I think Swift always takes sides with the latter. This paper tries to concentrate on the roles which Gulliver has and to see if Gulliver is Swift’s mouthpiece.
