The book called “Gulliver’s travel” is in many ways similar to “one thousand nights” and Aesop fable because, it uses strange situations in faraway land and also makes humorous comments on human nature.
It is therefore a fantasy with practical purposes.
The essential of the book describes what happens in Gulliver whenever he goes to the long sea voyage.
On the first occasion, his ship is wrecked and he finds himself the Lilliput land of the little people.
Later, he goes by an accident to a land giant called Brobdingnag.
On still another occasion, he has an adventure land talked horses.
In fact, all this little people of giant horses represent human being.
The author, Jonathan Swift, likes writing about people politics society and suggests from certain points of view of important problems in the country might appears very small important.
Swift also means some people that have a small mind and need to realize just how insignificant they are in the universe.
He suggests some horse mind is perhaps, good than some people or at least it is interesting hear intelligent speech come from horse.
Although, today Gulliver travel is read mainly for sake of stories originally. Swift wrote it in order to shock people and in this he succeed.
