Medieval analyses of molecular propositions include many non-truthfunctional connectives
in addition to the standard modern binary connectives (conjunction, disjunction,
and conditional). Two types of non-truthfunctional molecular propositions
considered by a number of 13th- and 14th-century authors are temporal and local
propositions, which combine atomic propositions with ‘while’ and ‘where’. Despite
modern interest in the historical roots of temporal and tense logic, medieval analyses
of ‘while’ propositions are rarely discussed in modern literature, and analyses of
‘where’ propositions are almost completely overlooked. In this paper we introduce
13th- and 14th-century views on temporal and local propositions, and connect the
medieval theories with modern temporal and spatial counterparts.
