 Naturally, as with any historical analysis, an investigation of these developments has intrinsic historical value in and of itself, independently of its possible contribution to modern debates. Indeed, medieval theories of consequence are a genuine medieval contribution: while medieval authors are clearly taking ancient Greek sources and ideas as their starting point, the emergence of theories of consequence as such is a Latin medieval innovation. But as it turns out, following the thread provided by the three key notions (TP), (ST) and (Co) as formulated above provides a suitable vantage point to investigate the development of the notion of consequence in the Latin Middle Ages. In other words, historical and conceptual analysis can easily be combined in this case.
