The 2024-2025 ACT Lecture Series reflects upon the place and role of private law in these shifting scenarios. It asks whether and how private law norms, doctrines, and institutions are both driving and responding to emerging conflicts among different value(s). What can or should be seen as the value(s) of private law? Is a monistic conception of value tenable in pluralistic societies, and how can pluralistic conceptions of value hold in times of polarisation? Are private law values commensurable? How does private law shape or could shape prevalent moral-political values or modes of socio-economic valuation across different institutions, such as the family, corporations and other organised economic activity, civil associations, or (non-)commercial relations? And, ultimately: Why private law?
