 Modern scholarship is still divided about the significance of the current of Averroism in the thirteenth century (for the more recent discussion see Imbach 1991; Hayoun/de Libera 1991; Bianchi 1993; Niewöhner/Sturlese 1994; Kuksewicz 1997; Brenet 2003, 21–22; Coccia 2005, 20–53; Hasse 2007b; Martin 2007; Calma 2010, 11–20, 367–373; Martin 2013; Akasoy &amp; Giglioni 2013). It was argued, for instance, that the “radical Aristotelians” of the thirteenth century were not “Averroists” in a strict sense (Van Steenberghen 1974, 531–534). But that much is clear: there existed at least four groups of authors who explicitly adopted the unicity thesis in one of their writings: Siger of Brabant and possibly other masters of arts in later thirteenth-century Paris; a second Parisian group in the early fourteenth century around Thomas Wilton, John of Jandun and John Baconthorpe; several Italian masters of arts at Bologna university in the fourteenth century; and a larger group of authors in Renaissance Italy and especially in Padua.
