Whether there are several powers of the soul?
Objections
❌ Objection 1 : It would seem that there are not several powers of the soul. For the intellectual soul approaches nearest to the likeness of God. But in God there is one simple power: and therefore also in the intellectual soul.
❌ Objection 2 : Further, the higher a power is, the more unified it is. But the intellectual soul excels all other forms in power. Therefore above all others it has one virtue or power.
❌ Objection 3 : Further, to operate belongs to what is in act. But by the one essence of the soul, man has actual existence in the different degrees of perfection, as we have seen above (Question [76], Articles [3],4). Therefore by the one power of the soul he performs operations of various degrees.
