 Even for those within the Thomistic tradition, Scotus’ arguments about the univocity of ‘being’ had to be taken seriously. On the one hand, the word does not seem to be straightforwardly equivocal, in the sense of being subordinated to more than one concept, for we at least have the illusion of being able to grasp ‘being’ as a general term. As Scotus pointed out, in an argument reproduced by all who considered the issue (dubbed “the famous argument from a certain and a doubtful concept” by the early Scotist Peter Thomae), we can grasp that something is a being while doubting whether it is a substance or an accident, and this surely involves having a relatively simple concept of being at our disposal. On the other hand, there does not seem to be any common nature involved, and in the absence of a common nature, Thomists thought that to call the term ‘univocal’ was inappropriate. What was needed was a way of allowing the concept to enjoy some kind of unity, while allowing the word to have a significate that was not a simple common nature. For many thinkers from the early fourteenth century onward, the distinction between formal and objective concepts provided the answer.
