PHILHERIT is a philosophical and interdisciplinary research project (covering the fields of the history of ideas, political science, economics, and law) which focuses on the inheritance institution. It aims to explore the relationship between inheritance and social justice by studying the different normative foundations of past and present proposals for a fair regulation of wealth transfers. Based on an analysis of the debates around this question from the nineteenth century to the present day, it examines the dividing line drawn in different periods and in different contexts between fair inheritance and unfair inheritance. The project follows two lines of study: 1/ an archeology of reforming thoughts on the inheritance institution; 2/ an normative philosophy which seeks to analyze and compare the various contemporary normative proposals relating to inheritance, inheritance law and inheritance taxation.
