Divine Simplicity: Is God Identical to His Thoughts?

Theophilus inquires,

I've been researching the doctrine of divine simplicity (DDS) recently and I've had a hard time figuring something out. On DDS, is it the case that God is identical with his thoughts? Surely on the view (as you say in your SEP article) God is identical with his omniscience. But does that also mean he is identical with the content of that attribute? 

I would appreciate your input on this question, and your SEP article has given me a lot to think about.
The good news for Theophilus is that he has stumbled onto a serious problem. The bad news is that there is no really satisfactory solution known to me.
 
On DDS, God is identical to his attributes. Omniscience is one of the divine attributes; ergo God is identical to omniscience. This seems to imply that God is identical to the mental states in which his omniscience is articulated.  But a good lot of what God knows is contingent, for example, that I am the author of the SEP entry in question. Someone else might have been the author of that encyclopedia entry, not to mention the fact that there might not have been any such entry, or any such encyclopedia.
 
If we think of knowledge as a propositional attitude, and if this holds for God as well as for us, then there are many contingently true propositions with respect to which God is in corresponding contingent mental states. For if it is contingent that p, then it is contingent that God is in the state of knowing that p. Thus God is contingently in the state — call it S — of knowing that there is such an on-line publication as the Stanford Encyclopedia of Philosophy.
 
But how can God be identical to S?  This, I take it, is the question that vexes Theophilus.  He is right to be vexed.  How can an ontologically simple God know contingent truths? 

The problem may be cast in the mold of an aporetic tetrad:

1. God is simple: there is nothing intrinsic to God that is distinct from God.

2. God knows some contingent truths.

3. Necessarily, if God knows some truth t, then (i) there an item intrinsic to God such as a mental act or a belief state (ii) whereby God knows t.

4. God exists necessarily.

The plausibility of (3) may be appreciated as follows.  Whatever else knowledge is, it is plausibly regarded as a species of true belief.  A belief is an intrinsic state of a subject.  Moreover, beliefs are individuated by their contents: beliefs or believings with different contents are different beliefs or believings.  It cannot be that one and the same act of believing has different contents at different times or in different possible worlds. 

That the tetrad is inconsistent can be seen as follows.  Suppose God, who knows everything there is to be known,  knows some contingent truth t.  He knows, for example, that I have two cats.  It follows from (3) that there is some item intrinsic to God such as a belief state whereby God knows t.  Given (1), this state, as intrinsic to God, is not distinct from God.  Given (4), the state whereby God knows t exists necessarily.  For, necessarily, if x = y, and x is a necessary being, then y is a necessary being. But then t is necessarily true.  This contradicts (2) according to which t is contingent.

Opponents of the divine simplicity will turn the tetrad into an argument against (1).  They will argue from the conjunction of (2) & (3) & (4) to the negation of (1). The classical theist, however, accepts (1), (2), and (4).  If he is to solve the tetrad, he needs to find a way to reject (3). He needs to find a way to reject the idea that when a knower knows something, there is, intrinsic to the knower, some mediating item that is individuated by the object known.

So consider an externalist conception of knowledge.  I see a cat and seeing it I know it — that it is and what it is.  Now the cat is not in my head; but it could be in my mind on an externalist theory of mind.  My awareness of the cat somehow 'bodily' includes the cat, the whole cat, all 25 lbs of him, fur, dander, and all.  Knowledge is immediate, not mediated by sense data, representations, mental acts, occurrent believings, or any other sort of epistemic intermediary or deputy.  Seeing a cat, I see the cat itself directly, not indirectly via some other items that I see directly such as an Husserlian noema, a Castanedan ontological guise, a Meinongian incomplete object, or any other sort of merely intentional object. On this sort of scheme, the mind is not a container, hence has no contents in the strict sense of this term.  The mind is directly at the things themselves.

If this externalism is coherent, then then we can say of God's knowledge that it does not involve any intrinsic states of God that would be different were God to know different things than he does know.  For example, God knows that I have two cats.  That I have two cats is an actual, but contingent fact.  If God's knowledge of this fact were mediated by an item intrinsic to God, a mental act say, an item individuated by its accusative, then given the divine simplicity, this item could not be distinct from God with the consequence that the act and its accusative would be necessary.  This consequence is blocked if there is nothing intrinsic to God whereby he knows that I have two cats.

I don't find externalism plausible, so I am left with an impasse.  I cannot see how God can exist without being ontologically simple. So I cannot reject (1). And of course I cannot solve or rather dissolve the problem by disposing of the presupposition that God exists. As for (2), I am not about to deny that there are contingent truths or that God knows contingent truths. As for (4), if God is simple, then surely he is a necessary being.  A being that is its existence cannot not exist.
 
Few philosophers will follow me to the conclusion that our tetrad is a genuine aporia.  Most theists will cheerfully deny (1). A few will deny (4) which implies the denial of (1). Atheists will dismiss the whole discussion as an empty academic exercise  since it is plain to them that there is no God. A few brave souls will deny (2) either by denying that there are contingent truths or that God knows them. And then there are those who will deny (3).  This I should think is the best way to go if there is a way forward.
 
Could we go mysterian on this? The limbs of the tetrad are each of them true, and so collectively consistent; it is just that we cannot understand how they could all be true.
