Rounding Out Arguments

Read these sections to learn how to round out arguments conceptually. The first section will distinguish between two types of argument: deductive and inductive. Pay careful attention to the difference between these two, and think about which kind of argument you use more often. The second section will help you identify arguments with a missing premise and determine how and when to supply this missing premise. It will also introduce you to the principle of charity and the difference between normative and descriptive statements – three very important terms! The third section shows you three rhetorical devices to hint at further argument without actually going through the argument: assuring, guarding, and discounting.
