Can God be onmi-max God when incompatibility arguments that we ignostics put forth presenting His attributes as conflicting and incoherent? Carneades maintains no, because as for instance. to be perfect He'd have to be all virtuous but as not fearing anything that He cannot be and thus cannot exist. This is more than a probability statement but a certainty by way of analysis wheres as other naturalist arguments would be probable.
Yet if we didn't discuss whether He could be virtuous or vicious, as David Ramsay Steele notes in " Atheism Explained : from Folly to Philosophy," then He is no kind of person we ever have known. even analogically.
Since He is disembodied, He has no brain with a mind. And have we ever observe such a being? No, and to argue otherwise is to commit the fallacy of ignorance, but then faith rests there.
We ignostics have many more such arguments.
Might the visitors here have their own misgivingings about His powers, revealing that He cannot exist?
