I argue that a tripartite analysis of simple statements such as “Bucephalus is a horse”, according to which they divide into two terms and a copula, requires the notion of a repeatable: something such that more than one particular can literally be it. I pose a familiar dilemma with respect to repeatables, and turn to Avicenna for a solution, who discusses a similar dilemma concerning quiddities. I conclude by describing how Avicenna’s quiddities relate to repeatables, and how both quiddities and (...) repeatables may contribute to a tripartite analysis of predication. (shrink)
