Read this excerpt from Jonathan Swift's "A Modest Proposal":
I shall now therefore humbly propose my own thoughts,
which I hope will not be liable to the least objection.
I have been assured by a very knowing American of my
acquaintance in London, that a young healthy child well
nursed is at least a year old a most delicious, nourishing,
and wholesome food, whether stewed, roasted, baked, or
boiled; and I make no doubt that it will equally serve in a
fricassee or a ragout
grant this food will be somewhat dear, and therefore very
proper for landlords, who, as they have already devoured
most of the parents, seem to have the best title to the
children
How does Swift use satire to achieve his purpose?
