  While almost everyone except Paul of Venice agreed that proper names must always be equivocal when used of two different people, not everyone wanted to say that they were univocal when used of the same person. Except for Roger Bacon, who thought of proper names as constantly receiving new impositions (see §7), the reason had to do with the definition of a univocal term as involving a concept or a nature predicable, at least in principle, of several individuals.  The usual solution was simply to redefine ‘univocal’ so that proper names were included, but the Categories commentaries of Albert of Saxony, Marsilius of Inghen and Paul of Venice contain fairly extensive discussions of the issue. Both Albert and Paul agreed in opposition to Marsilius that a proper name could be equivocal without being called univocal when used of one person.
