That does not help either. “Perfection” is as undefined or subjectively defined as any other “aggregate” attribute. A “perfect” dinner for a carnivore is not the same as a “perfect” dinner for a herbivore. A perfect dinner for a blind person is very different from a perfect dinner for a sighted person. Besides “perfection” is not immune to self-contradiction. A perfect bullet can penetrate any armor… while a perfect armor can withstand any bullet. There is no such thing as “maximally perfect” in a vacuum. Perfection only exists in relation to something.
Not to mention that “omnipotence” and “omniscience” are also virtually undefined. The literal meaning of being able to do “everything”, and knowing “everything” are clearly nonsensical. The more modern usage of being “maximally powerful” - meaning to ge able to do everything that can be done, or knowing everything that can be known simply changes the “goalposts”… since now we need to find out just “what” can be done and “what” can be known.
The point is that there is no coherent, objective definition of a GCB. After all it requires fantasy, and people have varying amount of fantasy. For example (and let’s not get distracted here) “my” GCB is able to perform “evil acts”, but does not choose to, while the traditional catholic concept of God that he is unable to act against his “nature”, and is unable to do evil acts. As such there can be no common ground even if one attempts to “stick to” the idea of “perfection”.
Fair points, Tyrion.
I think your examples point to something of perfection, though. For instance, what makes a “perfect” dinner for a herbivore is different from that of a carnivore, or what makes a “perfect” bullet is different from “perfect” armour. If, by perfection, we can mean the maximal fulfillment or actualisation of potential according to the nature of a thing, I think we can get to something of what we mean by GCB.
However, I’m not sure how attributes like omniscience – having the ability to know all things – and omnipotence – having the ability to do all things – provided neither of these attributes are contradictory to other attributes and GCB’s nature, can be “clearly nonsense”?
Certainly, there may be uncertainties about what attributes GCB could be objectively said to have, but I think there is room for discussion here. For instance, if GCB is able to do evil but chooses not to, that must mean that His being is not altogether aligned with His will. The Catholic alternative is that GCB not only chooses to not to evil but cannot do so because His very nature is the Good. Which one is greater: a GCB who has a disharmonious will and nature, or one that doesn’t? Moreover, we have to ask whether actually doing evil is a positive or negative attribute.
As I said, we might not be able to iron-out every attribute, but I think we can come to some definite conclusions.
Another example, for instance, is that GCB cannot be maximally or infinitely tall or short, since these attributes are measurable (and so, you could always conceive of an even greater being who is maximally tall + 1) and I don’t think generally considered “perfections”. Being tall is not a deprivation of “shortness”, or short a deprivation of “tallness”, whereas being ignorant is a deprivation of knowledge, and impotence is a deprivation of power.
