This position, that humankind shares one active intellect, was taken up by Parisian philosophers such as Siger of Brabant, but also widely rejected by philosophers such as Albertus Magnus, Thomas Aquinas, Ramon Lull, and Duns Scotus. Despite being widely considered heretical, the position was later defended by many more European philosophers including John of Jandun, who was the primary link bringing this doctrine from Paris to Bologna. After him this position continued to be defended and also rejected by various writers in northern Italy.
