Michael’s answer to a reader’s question about where to find a handy accounting of Thomistic philosophical terms mentioned Fr William Wallace’s The Elements of Philosophy, which contains pithy renderings of these polyvalent terms. I read Michael’s mention of the book, mentally checked-off on the issue, and went about my day.
But then I remembered that, given the reader’s original concern as a teacher, Fr Wallace’s The Elements of Philosophy is carefully indexed to the corresponding articles on philosophical and theological terms to be found in the New Catholic Encyclopedia! Indeed, if I remember correctly, Fr Wallace wrote the thing as a distillation of the corresponding NCE content. So, to the original question and for our other readers, don’t forget that the New Catholic Encyclopedia (together with its 2003 update) has articles on these essential philosophical terms (many of which were authored by Wallace, Weisheipl, and thomistic lights).
