Abstract

D'Ailly was an eminent nominalist theologian and one of the group of ecclesiastical statesmen who engineered the termination of the Great Schism. It is this dual roll that lends particular interest to his political thought, which reflects both his attempt to solve the urgent ecclesiastical-political problems of the times and the theological "voluntarism" characteristic of the Ockhamist school to which he belonged. D'Ailly was one of the most eminent of the Conciliarists, and to the present volume is appended a complete text of one of his two principal Conciliar tracts, the "Tractatus de materia concilii generalis."
