Chapter 7 - Case Construction


In Chapters 4–6, we have considered factors that strengthen or weaken individual arguments, focusing especially on the evidence on which an argument is based and on the patterns of inference that are expressed in various argument schemes. Usually, though, these individual arguments are combined into larger units to advance or defeat a resolution, the main claim in a controversy. The structure of subsidiary claims and evidence to support or oppose a resolution is called a case. If the case supports the resolution, it is called an affirmative case (because it affirms) and if it opposes the resolution, it is referred to as a negative case (because it negates).
