describe gulliver as anarrator

We generally trust Gulliver's statements even though they are about fantastic beings and places. We do not need to believe that such things actually happened. Instead we should recall that Swift has important lessons to teach though the satire and the imaginary narrator of these fictional travels. Beyond that, we might trust Gulliver because of his thoughtfulness and prudence in some ways and because he is willing to relate good news and bad news, good and bad things about various kinds of people, in the same even tone.
