The semantics of anaphoric pronouns or relativa grammaticalia played an important role in the treatises of both grammarians and logicians in the middle ages. However only very recently has the theme again received comparable attention in transformational grammar and the analytic school of linguistic philosophy under the influence of Geach. Here philosophers of language take particular interest in the question of how far these expressions can be seen as colloquial counterparts of the bound variables known from predicate logic.
This work shows that scholastic theories of suppositio relativorum underwent a development in the 14th century and that the theories which gradually emerged anticipated in important ways the insights of recent linguistic philosophy.
This thesis is illustrated by editions of selected texts of the logicians of the new continental universities of Vienna and Prague of the end of the 14th and the beginning of the 15th centuries and make it clear that the often asserted decline of scholasticism had not yet set in in the period after Ockham and Buridan.
