In A Modest Proposal by Jonathan Swift, find places in the proposal where the speaker uses logical appeals to support his suggestions.

There are numerous passages that support Swift's 'logic'. The example below is Swift's argument that even as slaves the Irish are not worth as much as they would be on the dinner table.

I am assured by our merchants, that a boy or a girl before twelve years old, is no saleable commodity, and even when they come to this age, they will not yield above three pounds, or three pounds and half a crown at most, on the exchange; which cannot turn to account either to the parents or kingdom, the charge of nutriments and rags having been at least four times that value.
