In the last post, I tried to buttress Aquinas's (alleged) argument that the soul and its powers cannot be one and the same because I always have a soul, whereas I do not always exercise my soul's powers (there are times when I sleep, for instance, when I do not think). I further pointed out in the last post that each of the soul's powers require different circumstances for their actualization, and that provides another reason to say that the soul's powers must be distinct from each other (and, consequently, from the soul itself).
Now, suppose that we grant this. Still we might wonder: what sorts of things are the soul’s powers? According to Aquinas, they are qualities of the soul, perhaps similar to the way that a pale skin color is a quality of Socrates.
Of course, to compare the soul’s powers to the color of Socrates’ skin might suggest that the soul’s powers can be gained and lost, just like the color of Socrates’ skin. After all, Socrates’ skin color can change --- as would happen, say, if he went to the beach and got a tan. So surely the soul’s powers can change too.
But Aquinas rejects this, insisting instead that although the soul’s powers are qualities of the soul, they cannot be gained and lost in the way that Socrates’ skin color can. On the contrary, the soul’s powers are not the sorts of features that can ‘come and go’. Rather, they are permanently attached, so to speak, to the soul itself (so long as the soul exists).
I should note that Aquinas does not, so far as I know, ever offer an argument for the claim that the soul’s powers are qualities. But he did make this claim more than once throughout the course of his career, so I think we can safely assume that Aquinas is firmly committed to the idea that every human soul is accompanied by a set of distinct powers (qualities) that are permanently attached to it (so long as that soul exists).
One could easily take these ideas from Aquinas and generalize them. That is, one could easily insist that any power must be distinct from its basis when the thing that has the power in question also has its basis for any period of time when that power is not exercised. So, that is one interpretation of Aquinas's theory of powers.
