Does God have free will?, page-5

Surely a being with absolute power and authority must have the ability to redefine perfection (there's no higher authority imposing a standard), and therefore to choose how to act "perfectly". In terms of the original post, there wouldn't have to be a "need" for god to change its mind, god could just decide to do so.

If there is a problem here (and I appreciate the comment that the issue 'used to trouble you when you were a theist') then it stems from the premise that there is a perfect, all knowing, perfectly prescient, all powerful, and possibly "outside of time" being (not to mention swayable by prayer and interventionist but unchanging, favouritist but just, all-loving but reward/punishment orientated, and so on). The premise is made with no regard for logic, so it's not surprising that considering the tension between the supposed attributes of such a being is logically problematic. (Of course, if you are a theist you can just revert to the "I dunno" fall-back position and say that god and its attributes are beyond human comprehension.)

It's a bit like positing the existence of a five-sided square and trying to discuss its appearance. There's a simple answer: there's no such thing. (Or, presumably, if you're a five-sided-squarist, then the answer is that the attributes of the great and divine five-sided square are beyond mortal comprehension.)
