||Aristotle's views in this area are hotly disputed. While everyone agrees that Aristotle sees understanding and reasoning as cognitive achievements that go beyond the sorts of perception animals are capable of, there are disagreements about the nature of these activities and the power responsible for them, the intellect. First of all, scholars disagree about how to interpret Aristotle's claim that the intellect is unmixed with the body and has no bodily organ, claims he defends in De Anima 3.4. Some take this as showing that the intellect can operate apart from the body in a way that other powers of the soul cannot. Others maintain that Aristotle is only claiming that the intellect has no specific bodily organ. There is also disagreement about the active and passive intellects discussed in De Anima 3.5. Most scholars think the passive intellect is a power of the human soul and many think this about the divine and unaffected active intellect as well. Others, however, think that this active intellect is Aristotle's God, the unmoved mover of Metaphysics Lambda, or another entity outside of the human soul.
