A European tradition of new and direct interpretations of Aristotle developed which was eventually strong enough to argue with partial success against some of the interpretations of Aristotle from the Islamic world, most notably Averroes' doctrine of their being one "active intellect" for all humanity. Notable "Catholic" (as opposed to Averroist) Aristotelians included Albertus Magnus and Thomas Aquinas, the founder Thomism, which exists to this day in various forms. Concerning the nous, Thomism agrees with those Aristotelians who insist that the intellect is immaterial and separate from any bodily organs, but as per Christian doctrine, the whole of the human soul is immortal, not only the intellect.
