I have no idea what that even means 'has life to the fullest life possible'? It seems to me that you are either alive or not.
Another title, I was thinking about is As-Samad. It means to be filled absolutely. That means everything is somehow intensified in to it's ultimate. It has everything in it to the absolute.
Al-Hayu is used through out Quran, As-Samad only once, but in a very important Surah, Suratal Tawheed (unification) (Surah 112) also known as Suratak Ikhlas (sincerity).
The point is these titles, you can ignore coherency as far balance of virtues go for a brief moment (if they are mutually exclusive, hold on to it for a brief second), and just look at it from no longer "greatest possible being" "But most life possible being" and the "the All things filled in it" (Samad), either this one or that, and you can prove what ontological argument sought to do, by showing, that absolute in life or filled absolutely with all - is synonymous with being Necessary. Then when you get that, Necessary implies existence and Oneness, I will elaborate why.
It's simple mathematically - include all possible worlds except this one, and it's just one possible world life wise or filled wise (depending on which title we go by Al-Hayu or As-Samad) away from being absolute and necessary. Include this world, and all possible worlds, and life wise, you got the Necessary Being. Filled wise, you got the Necessary being.
Therefore the relativeness or if greatness is a social construct or if morality has any reality or is completely a false notion, doesn't matter.
Then now we can talk, what is morality, what is goodness, what is greatness, and if these should be applied to Al-Hayu or As-Samad. You can conclude that since Greatest possible being (ontological original argument) includes wisdom, mercy, goodness, generosity, love and would include life wise, power wise, that since life Wise God is Al-Hayu defined to be that way as well, you can just prove Al-Hayu (similarly how ontological argument sought to prove God except with coherency problem you brought up), and then prove since Al-Hayu by definition is One possible, and so God is also only One rational possibility.
God is Al-Hayu/Samad.
Al-Hayu/Samad is proven to be One (possibility life wise, or filled wise).
Therefore God is proven to be One.
And same applies with Necessary.
And if you prove God is Necessary, he default exists.
So that's how I re-routed it. Lol programming adjustments. So then it proves God is logical coherent and that the original ontological argument is also true without need to get into debate about coherency of God.
We re-routed it through different titles of God (Al-Hayu and As-Samad) and proven that Al-Hayu/Samad exists by virtue of being necessary. Then we know this attribute of the God concept or title - would apply to God or maximally great being. Therefore we can conclude, it's not incoherent, to see maximally great.
In other words, quality wise, we put that on ignore. Focused on life or being filled with ALL to absolute degree. And that proves Necessity (exists in all possible worlds) in terms of existence. Then we can conclude Al-Hayu cannot but be seen to exist.
A short way to argue all this:
- If Necessary Being is coherent, then we can only see it exists.
- Necessary being is a coherent concept (we can show that just by even ignoring greatness and goodness as being part of reality or just illusions, just focus mathematically life wise or filled wise by other two titles al-Hayu or As-Samad)
- Therefore we see a Necessary being exists.
