In a similar fashion, Swift shows that philology and scholarship betray the best interests of the Luggnaggians; pragmatic scientism fails in Balnibarbi; and accumulated experience does not make the Struldbruggs either happy or wise. In his topical political references, Swift demonstrates the viciousness and cruelty, as well as the folly, that arise from abstract political theory imposed by selfish politicians. The common people, Swift says, suffer. He also cites the folly of Laputan theorists and the Laputan king by referring to the immediate political blunders of the Georges.
The Travels is structured very much like a variation on the question, "Why are people so often vicious and cruel?" and the answer, "Because they succumb to the worst elements in themselves." Man is an infinitely complex animal; he is many, many mixtures of intellect and reason, charity and emotion. Yet reason and intellect are not synonymous — even if they might profitably be; nor are emotion and charity necessarily akin to one another. But few people see Man as the grey mixture of varying qualities that he is. Man oversimplifies, and, in the last book of the Travels, Swift shows us the folly of people who advance such theories. In his time, it was a popular notion that a Reasonable Man was a Complete Man. Here, Swift shows us Reason exalted. We must judge whether it is possible or desirable for Man.
The Houyhnhnms are super-reasonable. They have all the virtues that the stoics and Deists advocated. They speak clearly, they act justly, and they have simple laws. They do not quarrel or argue since each knows what is true and right. They do not suffer from the uncertainties of reasoning that afflict Man. But they are so reasonable that they have no emotions. They are untroubled by greed, politics, or lust. They act from undifferentiated benevolence. They would never prefer the welfare of one of their own children to the welfare of another Houyhnhnm simply on the basis of kinship.
