Citations of the ST in this volume follow this basic tripartite format: III.3.5. The initial capital roman letters indicate the part (in this case the third part), the second element in arabic numerals indicates the question within that part (in this case the third question), and the third element in arabic numerals indicates the article within that question (in this case the fifth article). The second part of the ST is divided in two sub-parts: I-II and II-II. More elaborate references will indicate the precise location within an article using further indicators found in the list of abbreviations. These are clearly explained in Frederick Christian Bauerschmidt’s chapter in this volume. Other texts by Thomas are cited in standard format. These are published in many editions and online: bibliographical references to the best editions can be easily found, for example, in Bauerschmidt’s Thomas Aquinas: Faith, Reason, and Following Christ (Oxford University Press, 2013), 317–22.
