Whether the irascible and concupiscible appetites obey reason?

❌ Objection 1 : It would seem that the irascible and concupiscible appetites do not obey reason. For irascible and concupiscible are parts of sensuality. But sensuality does not obey reason, wherefore it is signified by the serpent, as Augustine says (De Trin. xii, 12,13). Therefore the irascible and concupiscible appetites do not obey reason.

❌ Objection 2 : Further, what obeys a certain thing does not resist it. But the irascible and concupiscible appetites resist reason: according to the Apostle (Rm. 7:23): "I see another law in my members fighting against the law of my mind." Therefore the irascible and concupiscible appetites do not obey reason.

❌ Objection 3 : Further, as the appetitive power is inferior to the rational part of the soul, so also is the sensitive power. But the sensitive part of the soul does not obey reason: for we neither hear nor see just when we wish. Therefore, in like manner, neither do the powers of the sensitive appetite, the irascible and concupscible, obey reason.
