Abstract

Arriaga is an early modern scholastic who recognizes the importance of relations to philosophical discussions. He offers a classification of different kinds of relations, focusing on the distinction between categorial relations and transcendental relations. I suggest that this distinction might be seen as akin to one version of the modern distinction between external and internal relations. Like Suárez, whom he characterizes as a “giant among the scholastics,” Arriaga offers a reductionist account of categorial relations. He criticises Suárez’s account, however, for formally identifying a relation with the foundation in one relatum, something Suárez does in order to preserve a real distinction between converse relations. Arriaga, in contrast, argues that a categorial relation is formally identical to the foundation and terminus. Arriaga gives less attention to transcendental relations, even though he thinks they are real relations, but I offer some suggestions for how he may be thinking about them.
