Who are the brutish beings in Gulliver's Travels?

In "Gulliver's Travels," the brutish beings are the Yahoos, a race of uncivilized, animalistic creatures that resemble humans but exhibit grotesque and savage behaviors. They embody the basest instincts and vices of humanity, serving as a stark contrast to the rational and refined Houyhnhnms, a race of intelligent horses. The Yahoos symbolize the darker aspects of human nature and critique the moral failings of society. Through his interactions with them, Gulliver reflects on the potential for savagery within humanity itself.
