Abstract: For a symposium marking the centenary of MacPherson v. Buick, we identify three common characterizations of Cardozo’s famous opinion that purport to explain its importance. Unfortunately, each of these characterizations turns out to be a myth. MacPherson is worthy of celebration, but not because it recognizes that negligence law’s duty of care is owed to the world, nor because it displays the promise of an instrumental, policy-oriented approach to adjudication, nor because it embraces a nascent form of strict products liability. These myths of MacPherson reflect deep misunderstandings of tort law, and of Cardozo’s distinctively pragmatic approach to adjudication. Ironically, although they have been largely fostered by progressives, the myths lend support to the cause of modern tort reform. By contrast, an accurate appreciation of MacPherson’s virtues permits an understanding of negligence, tort law, and common law adjudication that provides grounds for resisting regressive reforms.
