Within the broad scheme of Gulliver's Travels, Gulliver seems to be an average man in eighteenth-century England. He is concerned with family and with his job, yet he is confronted by the pigmies that politics and political theorizing make of people. Gulliver is utterly incapable of the stupidity of the Lilliputian politicians, and, therefore, he and the Lilliputians are ever-present contrasts for us. We are always aware of the difference between the imperfect (but normal) moral life of Gulliver, and the petty and stupid political life of emperors, prime ministers, and informers.
In the second book of the Travels, Swift reverses the size relationship that he used in Book I. In Lilliput, Gulliver was a giant; in Brobdingnag, Gulliver is a midget. Swift uses this difference to express a difference in morality. Gulliver was an ordinary man compared to the amoral political midgets in Lilliput. Now, Gulliver remains an ordinary man, but the Brobdingnagians are moral men. They are not perfect, but they are consistently moral. Only children and the deformed are intentionally evil.
Set against a moral background, Gulliver's "ordinariness" exposes many of its faults. Gulliver is revealed to be a very proud man and one who accepts the madness and malice of European politics, parties, and society as natural. What's more, he even lies to conceal what is despicable about them. The Brobdingnagian king, however, is not fooled by Gulliver. The English, he says, are "odious vermin."
Swift praises the Brobdingnagians, but he does not intend for us to think that they are perfect humans. They are superhumans, bound to us by flesh and blood, just bigger morally than we are. Their virtues are not impossible for us to attain, but because it takes so much maturing to reach the stature of a moral giant, few humans achieve it.
