Whether we should distinguish irascible and concupiscible parts in the superior appetite?

❌ Objection 1 : It would seem that we ought to distinguish irascible and concupiscible parts in the superior appetite, which is the will. For the concupiscible power is so called from "concupiscere" [to desire], and the irascible part from "irasci" [to be angry]. But there is a concupiscence which cannot belong to the sensitive appetite, but only to the intellectual, which is the will; as the concupiscence of wisdom, of which it is said (Ws. 6:21): "The concupiscence of wisdom bringeth to the eternal kingdom." There is also a certain anger which cannot belong to the sensitive appetite, but only to the intellectual; as when our anger is directed against vice. Wherefore Jerome commenting on Mt. 13:33 warns us "to have the hatred of vice in the irascible part." Therefore we should distinguish irascible and concupiscible parts of the intellectual soul as well as in the sensitive.

❌ Objection 2 : Further, as is commonly said, charity is in the concupiscible, and hope in the irascible part. But they cannot be in the sensitive appetite, because their objects are not sensible, but intellectual. Therefore we must assign an irascible and concupiscible power to the intellectual part.

❌ Objection 3 : Further, it is said (De Spiritu et Anima) that "the soul has these powers"---namely, the irascible, concupiscible, and rational---"before it is united to the body." But no power of the sensitive part belongs to the soul alone, but to the soul and body united, as we have said above (Question [78], Articles [5],8). Therefore the irascible and concupiscible powers are in the will, which is the intellectual appetite.
