Professor Duncan Kennedy (Carter Professor of General Jurisprudence (Emeritus), Harvard Law School) held the Chaire Michel Villey 2019. The lectures were scheduled for 13 and 14 June 2019, which is now in the past ("The Rise and Fall of the Western Legal Tradition" et "Legal Reasoning and Adjudication"). However, Professor Kennedy graciously shared his outline and (open access) references with preparatory readings.
