Among the many editions and translations of Thomas Aquinas’ work, I have found Thomas Gilby’s two handy collections of philosophical and theological texts quite helpful over the years. His thematic approach can guide your interest and lead you to the primary text. Thus, in the first quotation below, the reference is to the Summa Theologica, Ia (First Part) Ia (Question One) 1 (Article One) ad.2 (His answer to objection two). That citation will lead you to the text, whether the translation is in the Benziger collection or in the multi-volume Blackfriars translation. The specific quotations I used in the America column are marked by an asterisk. Let me know if there are favorites of your own that I should consider or if, over the years, I have muddled the citation.
*1. In the field of human science, the argument from authority is weakest. Summa Th. Ia.1. ad 2
