Abstract Logica modernorum. A critical note on Habermas’s portrait of medieval philosophy In his monumental history of philosophy, the eminent scholar Jürgen Habermas has managed to provide us with a thorough and very nuanced overview of thousands of years of western thought. The famous philosopher paints an impressive picture of the vicissitudes of the modernisation processes featuring in the history of western philosophy. The Leitmotiv of Habermas’s narrative is the way in which throughout history philosophy dealt with the question concerning the relationship between faith and reason. When it comes to the Middle Ages, it is not surprising that Habermas should focus on the opposition between Thomas Aquinas and William of Ockham. However, by confining himself to the concepts of fides and ratio, he completely overlooks thirteenth-century developments in the domain of logic. To take note of these developments is fundamental to understand the process of modernisation in philosophy. The aim of this paper is to fill in the gap, by concentrating on thirteenth-century discussions of necessity and (logical) consequences.
