 Peter of Spain’s logical works are commonly characterised as revealing a moderately ‘realistic’ outlook. To explain the contents of linguistic expressions and the function of logical terms, he is inclined to focus on their relationships to some extra-mental reality. This can be shown from the way in which he discusses the use of the word est (is), his account of suppositio simplex, and the way he analyses the occurrence of the word ‘necessarily’ in propositions. Moreover, his conception of the consecutive expression ‘if’ clearly shows his tendency to put the domains of reality and language on a par. (However, not all linguistic expressions are connected with extramental reality. Although ontology always plays a role in his accounts of language, it would appear that Peter is especially interested in the contents of linguistic epressions. In that regard it seems more appropriate to speak of an intensionalist semantics.)
