 Two trends in recent philosophical scholarship are of special note. These engage Aristotle’s categorialism in different ways. The first considers it directly, as a topic of investigation in its own right; see Shields (ed.) 2012. The second treats it more indirectly, either by considering issues in Aristotle’s philosophy on which his categorialism bears or, more generally, by advancing the tradition his categorialism inaugurated; see Haaparanta and Koskinen (eds.) 2012.
