  Apart from these topics, there are others that are closely related to categories and often discussed together with them. One involves trans-categorial terms, such as ‘being,’ ‘one,’ ‘true,’ and ‘good,’ which apply to all categories and are predicable of every term that falls within the categories. In the Middle Ages, these are known as “the transcendentals” and their status becomes controversial in the thirteenth century (see Gracia 1992b).
