Jonathan Swift uses irony in his "A Modest Proposal." Instead of deciding to condemn "the cold, calculus" of an immoral colonizer's, Great Britain's action against the poor Irish Catholics, Swift inverts the irony and pragmatically uses the profit value to estimate the raw value of starving Irish peasants in terms of animal's flesh. Thus, he is very effective in his use of "praise to blame" or extracting a current, market-place value for new-born flesh as opposed to the tough flesh of teenagers.
