 One of the issues that Aquinas touched on but did not settle was that of the number of rationes an analogical term was associated with. This issue stems from Aristotle’s Categories. As translated by Boethius, Aristotle introduced the distinction between univocal and equivocal terms by claiming that whereas univocal terms were subordinated to one substantiae ratio, equivocal terms were subordinated to more than one substantiae ratio. The word ‘ratio’ here is capable of various interpretations, including ‘definition or description’, ‘analysis’, or ‘concept’, but by the early fourteenth century logicians and theologians came to agree that the appropriate interpretation was ‘concept’. The second threefold division of analogy given above suggests the importance of a focus on concepts; and the question of how many concepts an analogical term was subordinated to came to be central. The nominalists held that so-called analogical terms were either metaphorical or were straightforwardly equivocal terms subordinated to two distinct concepts, but the Thomists were split. Analogical terms could be viewed as subordinated to an ordered cluster of concepts (possibly but not necessarily described as a disjunction of concepts); or they could be subordinated to a single concept which represents in a prior and a posterior manner (per prius et posterius).
