The responses to my original essay ondivine simplicity have been interesting to read. I am grateful to Theopolis forthe opportunity to contribute to this conversation, and I appreciate all of mydialogue partners to this ongoing debate over the doctrine of divinesimplicity. There are several themes that I wish to comment on below.
The Argument
Thefirst theme that I wish to comment on is the argument that I developed in myfirst essay. Here is the argument once again.
1) If God is free, then God can refrainfrom acting to give grace.
2) God is free.
3) Therefore, God can refrain from actingto give grace.
4) If God’s act to give grace is absolutelynecessary, then God cannot refrain from acting to give grace.
5) God can refrain from acting to give grace.
6) Thus, God’s act to give grace is notabsolutely necessary.
7) God’s existence is absolutely necessary.
8) Anything that is identical to God’sexistence must be absolutely necessary.
9) All of God’s actions are identical toeach other such that there is only one divine act.
10) God’s act to give grace is identical toGod’s one divine act.
11) God’s one divine act is identical toGod’s existence.
12) Therefore, God’s one divine act isabsolutely necessary.
13) If God’s one divine act is absolutelynecessary, then God’s act to give grace is absolutely necessary.
14) Therefore, God’s act to give grace isabsolutely necessary. [Contradicts 6.]
15) Therefore, God cannot refrain fromacting to give grace. [Contradicts 5.]
16) Therefore, God is not free.[Contradicts 2.]
In my first essay,I pointed out that most Christian theologians and philosophers accept (1)through (8). Then I explained that premises (9), (10), and (11) are onlyaffirmed by proponents of divine simplicity. From there, I derived 3contradictions related to divine freedom and divine grace. I have repeated theargument because it is not clear that my dialogue partners have adequatelyattempted to engage with the argument. As I explained in my first essay, anyonewishing to defend divine simplicity will need to remove the threecontradictions by pointing to premises in the argument that she rejects, andoffer a justification for why she rejects those premises. My dialogue partnershave not been entirely forthcoming about which premises they reject.
For example,consider Edward Feser’s reply. Feser comments on my argument from divinesimplicity to the necessary existence of the world. This is curious becausenone of the premises in my argument even mention the necessary existence of theworld. This leaves me to wonder if Feser read my original essay closely. To befair to Feser, he does at least attempt to identify which premise in theargument that he rejects. Feser says,
Now, what the doctrine of divine simplicity claims—contrary to what Mullins supposes (in what he labels premise (9) of his argument)—is not that all of God’s properties are identical and thus are necessary as he is, but rather that all of his real properties are.
Feser then goes on to say that he rejectspremise (9) because of a distinction between real properties and Cambridgeproperties. According to Feser, God is identical to His real properties, but Godis not identical to His Cambridge properties.
I find this reply from Feser curious for several reasons. First, it is curious because my premise (9) does not even mention the word property. What my premise (9) actually says is, “All of God’s actions are identical to each other such that there is only one divine act.” My actual premise (9) is something that proponents of divine simplicity explicitly endorse.[1] By this one act, God is said to will Himself and everything else that He has made.[2] Moreover, I intentionally avoided any mention of properties in the premises of my argument. I avoided this because, as I explained in my original essay, proponents of divine simplicity explicitly deny that God has any properties, forms, immanent universals, or tropes.[3] As the proponent of divine simplicity, Katherin Rogers, makes clear, the simple God does not have any properties. Instead, God is simply act.[4]
Second, I findthis reply from Feser curious because it appears that Feser is rejecting someother premise from some other argument from some other philosopher. It seems asif Feser has taken material from pages 195-196 of his book Five Proofs for the Existence of God and assumed that it addressesthe argument that I offered. In this book, Feser is responding to an argumentfrom the philosopher Thomas Morris, who offers an argument from the identity ofGod’s properties to the necessity of the created world. (Which again, is notthe argument I offer in my original Theopolis essay.) It appears that Feser hastaken this material and replaced “Morris” with “Mullins” for his blog post. Thiswould explain why Feser’s essay does not actually address my argument, and whyhe skips over premises (10) and (11).
Third, I find thisreply from Feser curious because it is not a legitimate reply to Morris’argument from simplicity to the necessary existence of the universe. Feser’sresponse to Morris’s argument is to appeal to the distinction between realproperties and Cambridge properties. According to Feser, God is identical toall of His real properties, but God is not identical to any of His Cambridgeproperties. (How God can lack all properties and yet have Cambridge propertiesseems to be a confusing notion, but I digress.)
This distinctionbetween real and Cambridge properties has nothing to do with Morris’ argument.As T.J. Mawson points out, God’s act of creating the universe is nothingremotely like a Cambridge property.[5]Divine actions are intrinsic to God. Given divine simplicity, divine actions areidentical to God. Divine actions like creating the universe or giving grace arenot Cambridge properties because they are intrinsic to God, and identical toGod. As Thomas Aquinas makes clear, “The manifold actions ascribed to God, asintelligence, volition, the production ofthings, and the like, are not so many different things, since each of theseactions in God is His own very being, which is one and the same thing.” (Summa Contra Gentiles II.10) I haveemphasized the production of thingsbecause it is important to note that God’s causal activity of producing theuniverse and of producing grace in sinners are actions which are identical toGod given divine simplicity. Any mention of Cambridge properties from Feserhere is quite simply a category mistake. It is nothing but hand-waving. Morris’argument, and others like it, are far more serious than Feser lets on.
On Appeals to Mystery
Joe Lenow’s essay mentions several interesting ideas that require more thought than a blog post can do justice. For example, Lenow mentions an argument that I have previously published elsewhere that seeks to show that divine freedom and pure actuality are incompatible. Lenow refers to a forthcoming paper of his where he develops a response based on the metaphysics of powers. Lenow’s work on the metaphysics of powers is intellectually stimulating, and demands more thought. However, since it is in reference to a different argument from the one I presented in my original essay for Theopolis, I shall have nothing more to say about here.
In reply to my Theopolis essay, Lenow says that there are different ways to think about the doctrine of divine simplicity. One could look at divine simplicity as a substantive metaphysical thesis, as I have in my original essay. Alternatively, one could look at divine simplicity as a consequence of a more fundamental claim about God—i.e. God’s essential unknowability. Since God is essentially unknowable, Lenow says we must deny all distinctions of God. Lenow claims that the unknowability of God is deep within the Christian tradition. He even says that God’s essential unknowability has a biblical basis in passages like Isaiah 55:8-9, which proclaims that God’s thoughts and actions are higher than our own.
I have several things to say in reply to this. First, the notion of essential unknowability is self-contradictory on its surface. One simply cannot know that God is unknowable. The very notion of knowing the unknowable is incoherent. If one knows X, then X is such that it is potentially knowable. If X is essentially unknowable, it is impossible to know anything about X including knowing that it is unknowable.
Perhaps one mightcomplain that I have not properly captured the notion of essential unknowability.In one place, Lenow says that God’s essential unknowability is “one of thedefining attributes of the divine life.” Lenow explains that it is an apophaticthesis that “every theological concept or claim must fail to describe God asGod truly is.” I think this is also self-contradictory. If the apophatic thesisis true, then it is false to say that essential unknowability is “one of thedefining attributes of the divine life.” This is because essentialunknowability is a theological concept, and thus fails to describe God as Godtruly is.
Second, divine simplicity does not follow from God’s essential unknowability. To start, divine simplicity is a theological concept or claim, and thus fails to describe God as God truly is. Moreover, if God is essentially unknowable, why should I think that I must deny all distinctions of God? If God is really unknowable, I am not in a position to say what can or cannot be denied of God. For all I know, God might be incredibly complex and have more distinctions than I can possibly imagine. Alternatively, God might have just two distinctions that are beyond my ken to know. Who knows? All bets are off if God is essentially unknowable. Any claim to know what the entailments are from God’s essential unknowability presuppose that one knows too much about the essentially unknowable God.
Third, I find it doubtful that God’s essential unknowability has its basis in a set of holy scriptures that explicitly claim to make God known to humanity. In Acts 17:23, the apostle Paul criticises the people of Athens for worshipping an unknown God. Why? Because Paul thinks that God has made Himself known through Jesus Christ. Are God’s thoughts above my own? Sure, but that does not tell me that God is essentially unknowable. Instead, it tells me that God is much wiser and more knowledgeable than I am. Isaiah assures me that I can know that God is very wise indeed. That is not an essentially unknown God.
What is the moral to draw from this? If divine simplicity rests upon the essential unknowability of God, this is not a great position for a proponent of simplicity to be in. The essential unknowability of God is self-contradictory, does not entail divine simplicity, and goes against the explicit teachings of scripture.
On Appeals to Analogy
Feser points out that the doctrine of analogy is about literal predication. I am aware of this fact, so I am not sure what Feser’s point is. Perhaps Feser is wishing to inform other readers, which is surely an important task. Also, I am not entirely sure what the doctrine of analogy does for divine simplicity with regards to my argument. Can analogical predication somehow remove a contradiction like “God is free and God is not free.” No. Classical theists are quite clear that God cannot be free if His actions are performed of absolute necessity.[6] No amount of analogical predication can make God’s free actions consistent with those actions being performed of absolute necessity. Can analogical predication somehow make God’s contingent and necessary actions identical? Of course not.[7] No amount of analogical predication can make necessity and contingency mean something completely different so as to remove the contradictions that I have pointed out. I think what Feser is really working with is equivocation.
In order for an analogical predication to be successful, one must be able to identify the sense in which the two predicates are being used in a similar way. In other words, one must find the univocal core of the analogical predication.[8] Otherwise, one is simply equivocating the terms, and changing the conversation. This is a point that Peter Leithart brings out in his essay. Despite all the appeals to analogical predication, proponents of divine simplicity have to rely on certain univocal concepts in order to establish their claims about the simple God.
On the Dire Consequences of Denying Divine Simplicity
Feser says that there are dire consequences if one denies divine simplicity. For example, if one denies divine simplicity then one has to give up on the uniqueness and ultimacy of God. Thus, if one denies divine simplicity, then one has implicitly denied the existence of God.
In reply, I say that there are some slippery slope arguments, and then there are some really slippery slope arguments. Feser’s assertion that denying divine simplicity leads to atheism is very slippery indeed. Feser’s claims assume an elaborate set of metaphysical theories that a Christian does not have to affirm in order to articulate a biblical doctrine of God. As I pointed out in my original essay, the doctrine of divine simplicity has no explicit biblical support. Instead, the doctrine has to be argued for on the basis of certain metaphysical assumptions, which also do not have any explicit biblical support.
The classical theist’s underlying metaphysical assumptions about mereology and what counts as a part are controversial and extravagant. The sort of merelogical assumptions that are at play in this argument are ones that I find implausible. As I pointed out in my original essay, proponents of divine simplicity assume that all properties, actions, and potentialities count as parts. Even existence counts as a part. I find it implausible that existence and actions count as parts. I find it implausible that the essential properties of an immaterial soul count as literal parts of a soul. I find it implausible that God’s accidental property of Creator counts as a part. I find it implausible that conceptual distinctions, like conceptually dividing God’s life up into conceptual temporal parts, count as literal parts.[9] I reject the mereological assumptions that are at play in many standard arguments for divine simplicity.
What happens if I deny divine simplicity along with its underlying mereological extravagance? I am left with a wide array of models of God and competing metaphysical positions. Let’s be clear about this fact. With debates over models of God, we are also considering debates over competing metaphysical claims.[10] Our options are not really Thomistic metaphysics or atheism. That is a false dichotomy. There are many other metaphysical theories that are available to the Christian who wishes to develop a biblical doctrine of God.
Moreover, thereare many alternative models of God that one can turn to if she denies divinesimplicity. The options are not classical theism or atheism. Here are a few ofthe other options: neo-classical theism, open theism, panentheism, pantheism,and process theism.[11]To be sure, some contemporary classical theists, like Feser, caricature theseother models as nothing more than superhuman deities. They even lump thesequite distinct models into the incredibly unhelpful, and uninformative,category of “theistic personalism.” But this is nothing more than a caricaturethat does not reflect serious scholarship. It might turn out that, upon closeexamination, these other models of God are not viable options. (Personally, Iwould rule out a couple of these models of God on biblical grounds.) But aChristian who takes seriously the problems for divine simplicity ought to takeseriously the available models of God instead of asserting that our options areclassical theism or atheism.
