Over the years, Reason in Law has established itself as the leading textbook for courses in legal reasoning, a critical aspect of the rule of law. This eighth edition brings the book’s analyses and examples fully up to date, adding new cases while retaining old ones whose lessons remain potent. It takes full account of the dramatic changes--and challenges--to legal reasoning that emerged from the Bush administration’s attempts to fight terrorism and also explores recent conflicts over same-sex marriage, gun control, hate crimes, and climate change.  The result is an indispensable introduction to an issue that lies at the heart of the workings of the law.
