As it sometimes happens, a research generated a new one. In the archives of the philosopher of law Gioele Solari an unpublished, completed paper was found, written between October 1948 and the summer of 1949 for the monthly «Il Ponte» edited by Pietro Calamandrei. Solari’s analysis of Luigi Einaudi’s «democratic liberalism» regards the years of his youth and those before the First world war: as the same author stresses, some theoretical traits come out, which did not change through Einaudi’s whole life.
