Gulliver schiwrecks on the island of Lilliput whose inhabitans are tiny people from whom learn the customs and culture, and fight with to defeat Blefuscu

Gulliver sets off for India but he finds himself on the island of Brobdignag, whose inhabitans are all giants

Gulliver lands on the fliyng island of Laputa, with its capital Lagado, whose inhabitans are philosophers and scientists, all involved in bizzarre and futile scientific research and speculations.

Gullivr arrives on the island of Houyhnhnms, whose inhabitans are intelligent horses that are served by the rude population of the Yahoos, again gulliver spends time learning their customs and traditions and their point of view for the race of the Yahoos. he assimilates them so well that, when he returns home, he finds himself disgusted by the humanness of his wife and children.

Lilliputians represent cruelty, pettiness and provincialism, that's because the politicians in the story were constructed with the inspiration of the politicians of Swift's time.

the giants represent the human vanity and self-love, Gulliver's descriptions reveal a great admiration for them and a deep disgust for the human body

the Laputans represent the abstract and intellectual thinking which has no connection with the reality and also a satire on England's military and colonial ambitions

this journey is one example of swiftian reversal. gulliver tries to convince the horses that he is not a yahoo but from the description of his own society the horses think that underneath the masquerade of civilisation, humans are ideed yahoos, only more sophisticated in their barbarism
