Gulliver and his master continue their discussion of concepts that are difficult for the master to comprehend — especially those related to lying and doing evil. Gulliver explains the role of Houyhnhnms and the Yahoos in Gulliver's country, and, of course, the master is shocked when he learns how the roles are reversed. The master observes that the Yahoos in his land are better adapted for their lives than Gulliver. The master also compares the Houyhnhnms to the Yahoos and determines that the Houyhnhnm, as an animal, is much more functional than the Yahoo.
