 Aquinas argues against this position in the Disputed Questions on the Soul ("Quaestiones disputatae de Anima"), and asserts that while the passive intellect is one specifically, numerically it is many, as each individual person has their own passive intellect.Passive intellect is identical with Aql Bil Quwwah in Islamic philosophy.Aql bi-al-quwwah, defined as reason, could abstract the forms of entities with which it is finally identified.
