I Theories on Suppositio theories

Over the last 50 years, medieval theories of supposition have attracted a great deal of interest both among historians of philosophy and systematically oriented philosophers. That is, some scholars are mostly interested in the historical importance of such theories, and therefore try to explain their development against a historical background. Others, however, estimate that the conceptual content of these theories may contribute to the development of new, original semantic systems, and therefore evaluate them against the background of current investigations in philosophy of logic and semantics. These are of course not mutually exclusive alternatives, yet in practice it is very difficult to combine both approaches.
