 James discusses individuation in two places: Quodl. I, q. 21 and Quodl. II, q. 1. I will focus on the first treatment, because it is the lengthier of the two and because the tenor of James’ brief remarks on individuation in Quodl. II, q. 1, despite certain similarities with his earlier discussion (Wippel 1994), make it hard to see how they fit into an overall theory of individuation.
