This anthology aims to add flesh to the bones and the supplements, reservations, and alternatives for a deeper understanding of the tradition of natural law throughout the medieval period. It runs contrary to the opinion so commonly held since the Renaissance, that any tradition deemed medieval has little or even nothing to offer to contemporary needs and interests. The essays contained herein put to bed such a notion with fresh and interesting takes on Thomas Aquinas, Martin Luther, natural law in the traditions of Golden Age Spain, and more.
