1. Introduction

This introduction provides an overview of contracts and the law of contract. It first explains what the law of contract is about and why it matters before discussing the tasks of contract law. It then considers the role of debates in contract law, unity and diversity in contract law, and central issues in contract law. It also examines the main perspectives about contract that have influenced English law, including perspectives that used to be historically important. In particular, it explores the notions of bargains and the will. The chapter goes on to address two very different understandings of contracts: one that sees it primarily as a bundle of rights, and one that sees it as a relationship between the parties.
