The Yahoos are, in the words of Mary P. Nichols, the author of “Rationality and Community; Swift’s Criticism of the Houyhnhnms”, “filthy, gluttonous, lewd, insolent, and violent” (1157). This is made obvious from the beginning of Part IV, during which Gulliver encounters the Yahoos for the first time. In this encounter the Yahoos “began to discharge their excrements on” (Swift 2589) Gulliver’s head. Gulliver also refers to them as the most “disagreeable” (Swift 2589) animal he has ever come across in his travels.

The lifestyle of the Houyhnhnms is unattainable for humanity, who cannot simply turn their emotions off, but aspects of the Houyhnhnms should be admired. While Gulliver is explaining war and lies to his master, it is made clear that the Houyhnhnms know nothing of either. Gulliver remarks that his master was having a hard time believing him because “doubting or not believing are so little known in this country” (Swift 2598). The Houyhnhnms are incapable of being dishonest, making doubt, and even opinions, something that they do not understand or place value
