This casebook is for first year students learning torts. It adopts the philosophy that tort is a fundamental area of the law, in the sense that it articulates and flexibly employs a suite of concepts--duty, right, reasonableness, causation, foreseeability, and more--that are present throughout legal thinking. Consequently, understanding tort law is, perhaps not unlike other areas of law, an exercise in gaining facility with a set of tools for addressing conflicts in the way people live. This casebook seeks to impart that understanding by using a diverse span of cases, organized to illustrate the way that rules require judgment to be applied, and that judgments of this kind frequently differ.
