The treatise featured in this volume consists of the first thirteen questions of Aquinas' massive Summa Theologiae and is by far the best introduction to Aquinas' views on two central questions of philosophical theology: Does God exist? and What is God like? It has been newly translated for this volume and appears alongside a new commentary by a leading Aquinas scholar. This volume is the second to be published in The Hackett Aquinas, a series of central philosophical treatises of Aquinas in a new, accurate, readable translations, each with a commentary that makes it the edition of choice for anyone wishing to approach a given treatise in depth in English.
