First, please be clear in your notation. You are using an upper-case X in (2), and a lower-case x in both the subscript of M and in the description of M(x). Do these x's have the same referent, or are they being used differently?
x (lower-case) is a variable that can refer to any state of affairs. X is a particular state of affairs (actual maximality (or full specificity) a property of a state of affairs or a set of states of affairs?[/b]
O.K., so your second premise is this:
(2) Suppose X is logically possible.
Where X is a particular state of affairs that is also a "fixed point" of the following relation:
M(x): A state of affairs such that God cannot cause a state of affairs x to obtain.
Now, if X is a fixed point of the relation M(x), then X must be among the set of states of affairs that would satisfy the variable x. So, we should be able to substitute 'X' for the variable 'x' in M. Now, look what you have by substituting 'X' for the variable 'x':
M(X): A state of affairs such that God cannot cause a logically possible state of affairs to obtain.
So, you have started from my definition of omnipotence, and then assumed in (2) that there exists a logically possible state of affairs ('X'😉 that (by substitution for the variable 'x' in the relation 'M'😉 cannot be brought about by an omnipotent being. All you have done in (2) is assume the existence of a logically possible state of affairs that cannot be brought about by an omnipotent being.
In effect, your argument goes like this:
First, you assume my definition of omnipotence.
You then reply "No, that can't be right, because I can suppose that there is a state of affairs that is both possible and that cannot be brought about by an omnipotent being. Given your definition
and this assumption, I can derive a contradiction."
My rejoinder: "So what? Given any claim of yours, if I suppose something that
explicitly contradicts your claim, I can derive a contradiction."
But just as my supposition would not show anything about the truth or falsity of your claim, so your supposition in (2) doesn't show anything about the truth or falsity of my definition of omnipotence. This is what we call "begging the question".
Maximally specific states of affairs are ways everything could be at a time, or possible totalities of facts, or mereological sums of all possible objects, properties and relations. The actual world, in its totality, is a maximally specific state of affairs. Each possible world, in its totality, is a maximally specific state of affairs.
A non-maximally specific state of affairs can be a part of another state of affairs.
