 As is evident, Sharpe’s analysis of the types of universality for linguistic terms is based on two distinct but compatible criteria: (i) the existence of a common nature directly or indirectly signified by them, and (ii) the universal mode of signifying – the latter being more important than the former. Thus, based on the satisfaction of these two criteria, Sharpe himself reduces the preceding division of the kinds of universality to a threefold partition: (i) terms that signify in a universal mode a common nature existing in re and which are thus properly common, such as ‘homo’; (ii) terms that signify in a universal mode but do not refer to any common nature in re and which are thus common in a less proper way, such as ‘chimaera’ and ‘persona’; finally, (iii) terms that do not signify in a universal mode and which are thus common in an improper way whenever they refer to a common nature existing in re , such as ‘hoc’ and other demonstrative pronouns (QsU, p. 71).
