Abstract: Lawyers have techniques to persuade decision-makers about what the law should be. Their normative toolkit uses arguments based on common values, storytelling, and framing to help us see our own values in a new light. These tools of reasoned argument enable us to engage in civil debate about divisive issues and to justify decisions in hard cases. Persuasion: Getting to the Other Side categorizes the arguments that lawyers use in debates about ambiguous or contested legal questions. It also explains how judges justify their decisions about what the law should be when the case involves competing values and there are plausible arguments on both sides. The goal is to provide law students with a toolkit to help them engage in reasoned arguments about what the law should be.
