The Hamlyn Lectures 2025 - Professor Dame Sarah Worthington: Lecture 1

The first of this year's Hamlyn Lectures on "The Paradoxes of Property Law: From Castles and Contracts to Information and Ideas"

Usha Kasera Lecture Theatre, University of Edinburgh Law School

The University of Edinburgh Centre for Private Law is delighted to host the first of this year's Hamlyn Lectures, delivered by Professor Dame Sarah Worthington The Paradoxes of Property Law: From Castles and Contracts to Information and IdeasThese lectures examine what is protected under the rubric of ‘property,’ and why this special form of protection is provided in some contexts but withheld in others. The focus is on the various paradoxes that confound expectations and complicate accepted orthodoxies in property law. These subtle but persistent irregularities provide useful insights in dealing with some of our more intractable modern problems concerning the allocation and protection of scarce resources.Although all laws serve a societal function, the framework of property law stands as a particularly powerful legal and normative institution. It structures and protects the acquisition, control, use, transfer and loss of access to valuable resources. Yet what, precisely, qualifies as ‘property’? What kinds of legal protection follow from that classification? And, crucially, what lies outside the “property box,” and with what consequences?The aim in this series of lectures is to determine whether the current architecture of property law is capable of responding adequately to increasingly strident modern demands concerning the allocation and protection of new and newly valued modern resources. Lecture 1: What Does It Mean to Own Something? <ul><li>Date: 5 November 2025, University of Edinburgh</li><li>Chair: Professor Hector MacQueen, FBA, FRSE, Emeritus Professor of Private Law, Edinburgh Law School</li></ul> This opening lecture addresses the foundational question: what does it mean to “own” something? It begins with assets we instinctively regard as property—a bicycle, a share, a patent—and contrasts these with other assets we also describe as “mine”, but which law treats differently—my privacy, my kidney, my idea, my data.Ownership typically implies a right to exclude, to transfer and to seek redress for interference. But how far do those rights and protections extend? When can others deprive us of our property? What happens when others take or use our property, or damage or harm it? Some of these rules conform to widely held expectations; others do not. The “anomalies” are revealing, suggesting deeply embedded normative intuitions that offer guidance in exposing and developing a more nuanced and coherent legal framework.
