 The influence of this form goes beyond 12th-century attempts to compose axiomatic philosophical/theological works in the tradition of Boethius’s De Hebdomadibus (like Alan’s Regulae Caelestis Iuris and Nicholas of Amiens’s Ars Catholicae Fidei). First, the form is taken up by Leibniz in his axiomatic works. Second, early medieval notions of science are indebted to these Neoplatonic models of science, models that continue to be influential even after the reappearance of Aristotle’s Posterior Analytics. Further, the geometric methods of “analysis” and “synthesis” (“resolutio/compositio”), which work to and from first principles or axioms and is linked to axiomatic method in both its Proclusian and Euclidean forms, is important not only for later medieval thinkers like Aquinas, but also for Descartes, Newton, and Galileo (Sweeney 1994).
