You have to realize that we're not actually deducing these definitions from God, but inducing it on a philosophical deity, one that either conforms or contradicts our definition of the word.
That definition being all powerful - the ability to do anything. If it contradicts that definition of the word, find a new word.
The result is a theory, not a reality
When talking about gods, there's no such thing as "reality", and nor are there 'theories', just assumptions. The assumption to many is that god is omnipotent - which means it can do anything.
That's why I have a problem with it when someone assumes his definition of omnipotence can somehow be used to prove God isn't omnipotent by any definition
Who did that? I stated that if god is omnipotent by definition, then it can do anything. It's other people here putting limits on an omnipotent god's abilities. I already said my god can do everything and anything - logical or not.
I point you to Superluminal's remark in the hope it helps: "I think SnakeLord is simply saying that the claim of omnipotence by theists completely dissallows the statement by them (during logical debates) "god can't..." whatever."
But "omnipotence", as far as our ability to comprehend and measure it goes, is limited to its logical construction.
It's very simple. Omnipotence is the ability to do anything. Whether we understand the absolute depth of anything isn't relevant to any being that is omnipotent and can do anything whether we understand it or not.
But to change the rules halfway is a kind of philosophical bait and switch.
Who's changed the rules? I stated that omnipotence allows a being to do anything, little more.
I didn't say the logical limitation limits God - as I explained above as well - but it does limit us. It sets the meaning, and that meaning should remain logically consistent.
Then you're debating with me for little reason. The meaning has at all times remained 'logically consistent'. It is logical to state that a being that can do anything, can also do the illogical. It is illogical to state a being that can do anything, can't do something.
This highlights the importance of agreeing on a definition beforehand, which the OP hasn't done (eg. "all-powerful" isn't a definition of omnipotence - see fallacy of definition)
All powerful is a definition of omnipotence - see the dictionary
(Having unlimited or universal power, authority, or force; all-powerful.)
And that would invalidate any argument which goes: A) Omnipotence means [insert logical definition]; B) God can't [insert illogical action]; therefore C) God isn't omnipotent. The definition in A relies on logic, and if the logic has changed or is discarded in B, the definition becomes meaningless and C is invalid, whatever it is.
Certainly. As I have tried to tell you several times now, an omnipotent god can do anything - illogical or otherwise, and thus "B" is non existant. To quote Superluminal once more:
"I think SnakeLord is simply saying that the claim of omnipotence by theists completely dissallows the statement by them (during logical debates) "god can't...""
I have a problem with the assertion that God should be able to do genuinely illogical things
I noticed. Ye of little faith. An omnipotent being can do anything. Oh and btw, "genuinely illogical" doesn't mean much coming from a human.
which a logical definition of omnipotence wouldn't allow
The definition of omnipotence allows anything. To add "wouldn't allow" is an illogical thing to say as far as omnipotence is concerned.
It becomes relevant when it's used in an argument, which you might not be doing, but it does happen.
No, it isn't relevant. Superluminal once more, (clearly he phrased it better than I can):
"I think SnakeLord is simply saying that the claim of omnipotence by theists completely dissallows the statement by them (during logical debates) "god can't..." whatever. This is completely different from god choosing to do or not do a thing."
Your statement was:
"If the definition of "omnipotence" (A) must necessarily exclude "not being omnipotent" (A'), that is a logical limitation put on "omnipotence". "
This is wrong. Saying that an omnipotent being isn't not an omnipotent being doesn't put limits on it's omnipotence because it could still be a not omnipotent being if it wanted to.
It's because we're human that we try to understand. Whether we can is usually besides the point. If we are in the image of God, then to be human is nothing to be ashamed of (muddying the image would be).
I think there's nothing to be ashamed of even though we're not 'in the image' of some god - other than the belief that we're in the image of some god which is quite shameful as far as I see it.
The only reason the concepts have any significance is because of what they could mean for us - not for God.
Certainly, and when we define a being as omnipotent, we are saying it can do anything. You can't then turn around and say that being can't do such and such - because it contradicts the claim of omnipotence.
