Analogy is the mean between univocation and equivocation. When things are named analogously, the analogous term has more than one meaning, but these meanings are somehow associated. “Being” when said of substance and accidents are such an analogous term. The issue of the analogy of “being” can be traced back to Aristotle. In Metaphysics IV, Aristotle points out that “being” when said of substance and accidents are either univocal or equivocal. Rather, it applies to both of them with reference to substance. The substance is its primary reference, whereas accidents are secondarily or derivatively referred to, as it is named so because of its association with substance. Such a way of using a term is later named signification per prius et posterius, which later develops into the analogy of attribution. Scotus argues against signification per prius et posterius, claiming that one could find no means between univocation and equivocation. He admits the existence of metaphysical analogy but denies analogy in the logical sense. One reason is that, according to Scotus, only univocal terms can be used as the middle term of a syllogism. When analogous terms are used in inference, they will cause the fallacy of equivocation. Such fallacy occurs when one term in a single inference has more than one meaning. For example, in the following argument, Every simple perfection is in God. Wisdom is a kind of simple perfection. Therefore, [wisdom is in God.] “Wisdom” is supposed to be an analogous term, as creaturely wisdom and the wisdom of God are different but somehow related, e.g., the latter is the source of the former. One difficulty of this interpretation is the fallacy of equivocation: The term “wisdom” in the minor signifies creaturely wisdom, whereas “wisdom” in the conclusion signifies divine wisdom. Supposing that Scotus is right, analogical unities are not strong enough to avoid the fallacy of equivocation, then the argument would be invalid. Cajetan agrees with Scotus that the analogy of attribution is in fact a kind of equivocation. However, in his De Nominum Analogia, he argues that a true mean between univocation and equivocation does exist, and that is the analogy of proportionality. “Being” is exactly a proportionally analogous term. In the analogy of proportionality, the concepts signified by the analogous term are proportionally the same. This thesis aims to analyze Cajetan’s theory of analogy based on his De Nominum Analogia. It will first introduce the origin of the problem of analogy, and historical debates around the issue. Then, we will see Scotus’s view on these issues. After that, we will focus on Cajetan’s three-fold division of analogy, his definition of the analogy of proportionality, and how he uses this notion to answer the difficulties proposed by Scotus. Besides, some further issues will be explored, such as whether Cajetan has distinguishes the analogy of attribution and the analogy of proportionality according to extrinsic denomination and intrinsic denomination, and whether Cajetan has therefore confused the order of logic and the order of metaphysics.
