No, i did not define God as existence...
Forgive me if I feel that you're blatantly lying to my face, then. You said: "it follows logically that God must be.....Existence Itself." You began every element of your proof claiming "if God is existence itself..."
How, then, are you not defining God as existence when that seems to be what you spent two posts doing?
I took the already agreed upon ideas about what constitutes God and deduced logically what must God be in order to fulfill those qualifications. My definition was derived from those criteria, I did not start from that premise. Thats what makes my argument valid. I have not specified anything about the Bible or Quaran or anything else, as I dont necessarily believe in those books.
I would argue that you forgot to include agency and self-awareness. Most people believe that God must be conscious in some form to be God (otherwise we may be talking about the Universe being "God's debris" or something). If you don't believe that God is conscious, you still need to define what God is beyond "existence itself".
Besides, how well do we really understand what 'existence' is anyway, that we can dismiss it as something simple? And say, "aw thats not God, god's gotta be something besides existence"...maybe thats why we never see him/her/it? By looking for God where it isn't.
Existence is a philosophical concept. A rock doesn't exist because a person philosophizes about it. Even if you define God as vaguely as "existence itself", you still haven't made God something "outside our brains". Perfect circles don't exist, either. Infinity doesn't exist. Not in the real world. They are concepts in our minds. (And if you're going to claim, as I suspect you are, that these things are trancendent, like God, you need to explain why that's the case. The perfect circle is a mathematical necessity, but God, unless defined so narrowly as "existence itself" or incorporating attributes like "existence itself" is not.)
I mean how come you gotta think God is separate from existence? Because medieval writers said so?
I didn't say he must be seperate from existence. I said that he can't be "merely existence" and still be God. If God is the same thing as existence, with no more attributes, then you're just talking about existence.
However, you still have to explain why God is "existence itself" in the first place. Just because it fits your proof, doesn't mean that it actually reflects the nature of God.
I dislike being accused of mangling the english language.
We already have a word for existence, it's existence. If your version of God is the same thing as existence itself, with no other attributes, then that is precisely what you are doing. If your version of God has more attributes, then you need to define them, which you haven't done.
All you've done in your "proof" is say "God exists because he's God". Using a similar logic, I can prove he doesn't exist:
Premise: God is the creator of the Universe (already established by you).
Premise: God is the most powerful being we can conceive.
Premise: A feat is more powerful when the one who performs it appears to lack the ability to perform it (Ant Lifting a Rubbertree Plant Theory).
Therefore, if God were not powerful enough to create the universe, but did anyway, it would be a more powerful feat than if he were powerful enough to create the universe easily.
Therefore, a nonexistent God who created the Universe would be the most powerful creator we could conceive, because he created the Universe without even having the power to exist.
Therefore, God doesn't exist.
(But this is why pure Aristotelian logic is fundementally flawed. You can create a logical proof of something, but that doesn't mean it's true. Just like I can make a fact claim that is neither true nor false. It's an artifact of language. Nothing more.)
