 From this point of view, the historical developments in the Latin Middle Ages, in particular from the 12th to the 14th century, occupy a prominent position. As will be argued, it is in this period that concepts and ideas inherited from Greek Antiquity (Aristotle in particular, but also the ancient commentators) were shaped and consolidated into conceptions of consequence that bear a remarkable resemblance to the Tarskian condition of material adequacy presented above. Thus, an analysis of these historical developments is likely to contribute significantly to our understanding of the current notion(s) of logical consequence.
