Swift has attacked rationalistic and abstract thinking in Laputa and pragmatic and amoral scientific thinking in Balnibarbi. Now he lambastes the so-called humane studies of the Moderns, particularly the historians and philosophers. On the whole, Swift argues, poetry and ancient philosophy are more admirable than other ways of gaining knowledge because they teach morality and decency. Swift pits the ancient authors, like Homer and Aristotle, against their commentators. Most literary commentators and most historians, Swift asserts, distort those they write about. Swift points to Didymus and Eustanthius, ancient scholars who misread and misrepresented Homer. Then he singles out Scotus and Ramus, who, he says, misrepresented Aristotle. Such modern philosophers as Gassendi and Descartes were once popular; now they are unfashionable. Newton, Swift says, will also become unfashionable in his turn. His conclusion is that modern authors have no substance. He reduces them to matters of fashion, not truth.
After satirizing the humanities and philosophy, Swift turns to the historians. History, Swift infers, is the tool of politics; it is misread and miswritten for selfish reasons. In the service of politicians, history lies — about virtue, wisdom, and courage.
