One of the troubles with these Aristotelian terms such as potentiality, actuality, and change, is that it's possible to sculpt them infinitely. For example, an acorn is potentially an oak tree, but hang on, a squirrel eats it, so now it is actually part of squirrel meat, and potentially squirrel poo. But squirrel poo itself is potentially part of the forest's composted floor, which of course, potentially feeds the surrounding trees.
This is quite entertaining, but it seems without constraints. I suppose Feser would say that God, since he is not created, unifies potency and act. But this is a bit like angels dancing on a pin-head, isn't it?
Wigginhall.
The Aristotelian approach takes infinity into account. In fact for much of the history of monotheism the universe has been considered as possibly infinite.
You are arguing with me as though I am proposing a Kalam Cosmological argument. I am not.
The question why something and not nothing though is not the same as why did something pop out of nothing.
What the argument boils down to is derived power. There cannot logically be an infinite chain of derived power (although that which derives power could have existed infinitely).
The chain of derived power must logically end in an actual power which is a unitary actual power.
Any infinite chain of derived power is like proposing an infinite chain of railway wagons which are moving themselves without a locomotive. Totally illogical.
Angels on pinheads and dewdrops on roses have no place here since any other proposal creates an infinite chain of derived power.....and that is not logical.
To continually conclude then that there are no constraints here is to either misunderstand that derived power observed is completely illogical if presented as an infinite linear chain rather than a hierarchical chain where the buck stops at an actual unitary power which is not material as material is only observed to have derived power.
Regarding Professor Feser...have you read or seen any videos of the Master? An introductory ad hominem attack by Bluehillside is a recommendation and endorsement I would have thought.
