Why were some Aristotelian ideas associated with Averroism condemned in medieval Europe?

In medieval Europe, certain Aristotelian ideas associated with Averroism were condemned because they were perceived as threats to the Christian faith. Masters at the University of Paris, known as Latin Averroists, prioritized philosophical rationalism over theology, often interpreting Aristotle through the commentaries of Averroës.12

Theological authorities were particularly alarmed by doctrines that contradicted core religious tenets, such as:

• The eternity of the world: Challenging the Christian belief in a temporal creation.12
• The oneness of the intellect: A theory suggesting a single universal intellect for all humanity, which denied individual personality and personal immortality.134
• Determinism: The assertion that human actions were necessitated, which undermined the concept of moral responsibility.34

Critics accused these thinkers of holding a "double truth"—maintaining that reason and faith could lead to contradictory conclusions. This growing rationalism and naturalism prompted the bishop of Paris and the archbishop of Canterbury to issue formal condemnations in 1277, prohibiting numerous propositions to protect the integrity of the faith against what they viewed as dangerous pagan and Islamic philosophical influences.12
