What quality of the Houyhnbns does Gulliver miss in England?

The quality of the Houyhnbns that Gulliver misses in England is their rationality and lack of vice. Throughout his travels, Gulliver is deeply impressed by the Houyhnbns, horses who embody reason, logic, and moral integrity. They live in a harmonious society where decisions are made based on rational thought rather than emotional impulses. This contrasts sharply with Gulliver's observations of human behavior back in England, where he perceives a plethora of vices, such as greed, deceit, and conflict.

Gulliver's experiences among the Houyhnbns highlight his disillusionment with humanity, as he longs for the rational and virtuous lifestyle that the Houyhnbns exemplify. Their society, devoid of vice and focused on reason, symbolizes an ideal that Gulliver believes is unattainable in human society. This yearning for the principled life of the Houyhnbns underscores the critical perspective Gulliver adopts towards the flaws he perceives in humans.
