The article I'm reading is by Eric Steinberg in Religious Studies 23 pp. 351-365, called "Newman's Distinction Between Inference and Assent." The article is a little more difficult than it needs to be, but we'll see where he's going. He is treating the development of Newman's understanding of inference and assent. I'm also slowly plodding through Johannes Artz's "Der 'Folgerungssinn' (Illative Sense) in Newmans 'Zustimmungslehre' (Grammar of Assent)" from Newman Studien.

I don't think that I'm going to focus on the illative sense, but anything by Artz is always good and helpful.
