Next we can look at study of intension and remission of forms: (Goubier and Roques 2017) is a good recent collection of work on this, Sylla (1982) shows how this work was related to, and to some extent originated in, disputations  about logic, and Dumont (2009)  shows how these debates were related to their theological context. We must not  forget, though, that modern scholarship on this topic goes back to at least Anneliese Maier (1964), whose work goes back to the 1930s, and that she was working in the tradition of Pierre Duhem. So there is a vast body of work on this topic, written by people with a variety of agendas. Despite this, it is a very interesting body of literature,  and, if it might seem impossibly complex, it is thus because it reflects the variety of medieval and early modern viewpoints on this material.
