This article aims to supplement our understanding of later developments within European universities, that is, Scholastic thought, by attending to how certain pre-Scholastics, namely, Peter Abelard and other twelfth-century philosophers, thought about artifacts and social constructions more generally. It focuses on the treatment of artifacts that can be cobbled together out of Abelard’s Dialectica. The article argues that Abelard attempts to sharply distinguish the world of things from the world of human-made objects. This is most apparent in his treatment of (...) creation and human acts of making. Yet there are places in his thought where we see some hesitancy. Many of Abelard’s peers seem to have drawn on the reasons why Abelard hesitates, and they blur the line between human-made objects such as houses and substances such as rocks and humans. Others seem to go further than Abelard—perhaps inspired by some of the thoughts that Abelard also entertains about social constructions such as days and speeches—and assert that even houses are merely convenient fictions.
