Structuring Arguments

These two sets of statements illustrate the most basic ways in which Western culture structures logical arguments. The first piles up specific examples and draws a conclusion from them: that’s inductive reasoning and structure. The second sets out a general principle (the major premise of a syllogism) and applies it to a specific case (the minor premise) in order to reach a conclusion: that’s deductive reasoning and structure. In everyday reasoning, we often omit the middle statement, resulting in what Aristotle called an enthymeme: “Since dairy products make me sick, I better leave that ice cream alone.” (See “Using Reason and Common Sense” in Chapter 4, “Arguments Based on Facts and Reason: Logos” for more on enthymemes.)

But the arguments you will write in college call for more than just the careful critical thinking offered within inductive and deductive reasoning. You will also need to define claims, explain the contexts in which you are offering them, consider counterarguments fairly and carefully, defend your assumptions, offer convincing evidence, appeal to particular audiences, and more. And you will have to do so using a clear structure that moves your argument forward. This chapter introduces you to three helpful ways to structure arguments. Feel free to borrow from all of them!
