“But the Unmoved Mover, as the source of all change, is the source of things coming to have the attributes they have.
This is a description of Kant's noumeon. This is a logical and necessary premise, however I would take issue with the terminology "unmoved mover".
A better description would be "eternal substance". Something that is eternal and unchanging cannot "move". It might only "apparently move" from a subjective viewpoint, like that of a human, but to an objective observer, who necessarily views all things and all times with equal clarity, "movement" is "impossible". Thank you Parmenides.
Hence He has these attributes eminently if not formally.
Wait. "HE"???????????????????/ Where the heck did we jump to the conclusion that its a HE? Please explain this snuck premise.
That includes every power, so that He is all-powerful.
If noumenon is all things that would include all conceivable power, axiomatically.
It also includes the intellect and will that human beings possess . . .
If noumenon is all things that would include all conceivable things, axiomatically.
so that He must be said to have intellect and will, and thus personality, in an analogical sense.
If noumenon is all things that would include all conceivable things, axiomatically.
However, it would be illogical to conclude that, as a whole, the vast expanse of all possible existence "has a personality".
It certainly contains or includes humans and humans have a Qualitative attribute we like to call "personality".
But the full scope and breadth of noumenon and its fundamental nature is BEYOND OUR HUMAN EPISTEMOLOGICAL LIMITS (Ein Sof).
It must have them in the highest degree, lacking any limitations inherent in a material being.
Now he says "it"? It must have all attributes that exist in all possible degrees, but not "unlimited" or "infinite" because INFINITY is an incoherent concept.
“Hence He not only has knowledge, but knowledge without limit, being all-knowing.”
Noumenon contains all possible things, including knowledge, but not "without limit".
It has no negative features or defects.
Noumenon has every possible (subjectively) "negative" feature and or defect because it is literally everything.
Those would be privations, absence of a positive attributes and the FM has all attributes fully actualized. All-good in an analogical sense.”
Noumenon is everything. There is absolutely no way to logically separate it into either exclusively "all good" or "all bad".
