What does Gulliver’s relationship with the Houyhnhnms symbolize?

Gulliver's relationship with the Houyhnhnms symbolizes his longing for an ideal society based on reason and virtue. The Houyhnhnms represent a rational and harmonious way of living, contrasting profoundly with the chaotic and flawed nature of humanity, as exemplified by the Yahoos. Through his experiences with the Houyhnhnms, Gulliver comes to admire their logical, peaceful, and virtuous lifestyle. This admiration reveals his inner desire to escape the follies and vices of human society in search of a utopia where reason prevails over irrationality and where moral integrity is foundational. His time with the Houyhnhnms leads him to a deep disillusionment with humanity, further illustrating this aspiration for a more idealized existence.
