TO VOLUMES 9 AND 10 OF THE TREATISE I am happy to present here the third batch of volumes for the Treatise project: This is the batch consisting of Volumes 9 and 10, namely, A History of the P- losophy of Law in the Civil Law World, 1600-1900, edited by Damiano Canale, Paolo Grossi, and Hasso Hofmann, and The Philosophers' Philosophy of Law from the Seventeenth Century to Our Days, by Patrick Riley. Three v- umes will follow: Two are devoted to the philosophy of law in the 20th c- tury, and the third one will be the index for the entire Treatise, which will 1 therefore ultimately comprise thirteen volumes. This Volume 9 runs parallel to Volume 8, A History of the Philosophy of Law in the Common Law World, 1600-1900, by Michael Lobban, published in 2007. Volume 10, for its part, takes up where Volume 6 left off: which appeared under the title A History of the Philosophy of Law from the Ancient Greeks to the Scholastics (edited by Fred Miller Jr. in association with Carrie-Ann Biondi, likewise published in 2007), and which is mainly a history of the p- losophers' philosophy of law (let us refer to this philosophy as A).
