During the last 29 years of his life at the University of California, Kelsen's appointment at the University and his affiliation was primarily with the Department of Politics and not with the School of Law. This is strongly reflected in his many writings in the field of political philosophy both before and after joining the faculty at Berkeley. In fact, Kelsen's very first book (see Section above) was written about the political philosophy of Dante Alighieri and it was only with his second book that Kelsen started to write book length studies about the philosophy of law and its practical applications. Baume speaks of Kelsen's political philosophy concerning judicial review as coming closest to Ronald Dworkin and John Hart Ely among the scholars active after the end of Kelsen's life.
