Abstract
This paper investigates rival views about the nature of time that were articulated in the fourth-century controversies over the Trinity. In his
Contra Eunomium
Basil of Caesarea refuted the definition of time put forward by his opponent, Eunomius of Cyzicus, and presented his own views on its nature. This study seeks to contextualize the views of both contestants polemically, theologically, and philosophically. It is argued that Eunomius’s definition of time has a Platonic pedigree. In addition, it is demonstrated that, in both his critique of Eunomius’s definition and the positive presentation of his own views on time, Basil draws upon his familiarity with the philosophical critique of Plato’s views, as found in Aristotle, the Peripatetics, the Stoics, and the Middle Platonists (and perhaps even Galen). Basil’s own views on time have been most immediately influenced by Middle Platonist, Peripatetic, and Stoic concerns.
