 Thomas Aquinas elaborated on Aristotle's distinction between the active intellect and passive intellect in his "Disputed Questions on the Soul" and his commentary on Aristotle's "De anima", arguing, against Averroes, that the active intellect is part of the individual human personality.A third school, of "Alexandrists", rejected the argument linking the active intellect to the immortality of the soul, while hastening to add that they still believed in immortality as a matter of religious faith.
