He taught jurisprudence at the University of Camerino, then at Siena, and was appointed to a chair at Padua in 1940. In 1948, he became professor of legal philosophy at Turin, where he remained until 1972. A positivist in spirit, his works included A Theory Of Judicial Norms (1958), A Theory Of The Legal Order (1960) and studies of Locke, Kant and legal positivism. Between 1955 and 1970, he also published three collections of essays. These writings had a similar place in Italian academic legal circles to the work of H. L. A. Hart in English jurisprudence.
