What is "mock utopia" and how much is it true for "Gulliver's Travels"? Tell me in details please.

A "mock
utopia" is a place that seems utopicor whose citizens believe it to be utopicbut underneath
has flaws that gradually become apparent. Aldous Huxley's World State in Brave New
World is a classic mock utopia. It is engineered to make everyone "happy,"
but the price is the human soul.

In , the Houyhyhnhnms,
who are intelligent horses, appear to have created a utopic, perfect society, and Gulliver
certainly comes to believe they have. The Houyhyhnhnms live in complete order and peace, basing
all their decision-making on rationality. They have no words for lying because they don't lie,
finding it irrational to do so. Gulliver finds this society far superior to his own.

The Houyhyhnhnms, however, turn out to be too rational, for they lack emotion and for
that reason, don't necessarily value life or have any special attachment to their offspring or
anyone else. For example, each Houyhyhnhnm couple is supposed to raise one girl and one boy, so
if they have two children of the same sex, they simply bring them to their society's annual
meeting and trade with another couple for a child of the opposite sex. Humans would probably
have trouble with that concept. Further, they don't mourn death: Gulliver, for instance, meets a
Houyhyhnhnm woman who comes calmly to lunch right after burying her husband at sea. This
passionlessness can be troubling.

We are meant to critique Gulliver's
excessive reaction to leaving their culture and returning to England, where he tries to live in
a barn with horses.
