In his treatsie, On the Reduction of the Arts to Theology, or, in Latin, De Redcutione Artium ad Theologiam, St. Bonaventure deals with the relation of the finite to the infinite, of the natural to the supernatural, in a way which well establishes his preeminence as a mystic, a philosopher and a theologian. This English translation (from Latin) and commentary brings to the modern day reader an appreciation of the return of all created things to God.

This volume is reprinted with a revised translation, introduction and commentary by Zachary Hayes, OFM, from the original by Emma Therese Healy, CSJ, in 1955.
