Why does Gulliver feel more at home with the Houyhnbns than with humans?

Gulliver feels more at home with the Houyhnbns primarily because he admires their rationality and absence of vice. Throughout "Gulliver's Travels," particularly in the section involving the Houyhnbns, Gulliver experiences a profound sense of alienation from human society due to its flaws, greed, and corruption. The Houyhnbns, who represent an ideal of rational thought and moral behavior, significantly contrast with the chaotic and often irrational nature of humanity.

Gulliver is captivated by the Houyhnbns' lifestyle, which is based on reason, logic, and harmony, and he finds comfort in their society, where there is no deceit, conflict, or selfishness. This admiration leads him to conclude that these noble horses embody the virtues he longs to see in his own species. As a result, his connection with the Houyhnbns stems not from mere preference but from a deep-seated yearning for a more virtuous and rational existence, making them a place where he feels he truly belongs.
