Gulliver misses the point, however, when he strains to become unlike the Yahoos and like the Houyhnhnms, even trotting like a horse and speaking in their neigh-like manner. He rejects the virtuous and eminently human Don Pedro because he does not resemble a horse and, like all humans, somewhat physically resembles the Yahoos. Having the physical shape or mannerisms of a Houyhnhnm or a Yahoo does not turn a person into either. The deciding factors are how he acts and whether he chooses good or evil.
