Answer: Gulliver learns much about alternative ways of living and comes to appreciate the ways that various peoples have improved upon the ways that he knew in England. He also appreciates what it is like to be much larger or smaller, much better or worse, much more practical or less intelligent, than others. He has seen how what is an important difference within a culture seems petty to outsiders. Overall, he sees many things more objectively and has come to despise the usual ways of humans where he lives. The horses are not really like the Houyhnhnms, so we realize Gulliver's mistake, but we sense that Gulliver is better off with a lot of time to himself to contemplate his experiences and what they mean for living well.
