Truths, Propositions, and the Argument for God from Logic

A correspondent asked me if I could address an objection he had encountered to the argument for God from logic. Here’s the objection as he quoted it, with my comments interspersed:

The authors equivocate when they make the leap to claim that the laws of logic are thoughts. The propositions themselves are certainly thoughts, but how can the truths that the propositions bear be thoughts?

"I want the truth!"I’m pleased that the objector concedes that “propositions … are certainly thoughts” because that’s a crucial step in the argument! However, the latter part of the question reflects a confusion. In our paper, we adopted the conventional definition of propositions as primary truth-bearers. But this doesn’t mean that propositions bear truths (as though truths were something other than propositions). Rather, it means that propositions are things that can bear the property of truth; they’re things that can be true. Given this definition, truths just are propositions; specifically, they are true propositions.

Anderson on Anderson

Dr. Owen Anderson of Arizona State University has posted some thoughts on my TGC article, “Can We Prove the Existence of God?”

I’m gratified that he thought the article worth commenting on; I only wish he’d read it a little more carefully. I was planning to respond before I discovered that the Pilgrim Philosopher has saved me the trouble.

Update: Owen has posted a reply here and there has been some interaction in the combox.

Canon Fodder

My good friend and colleague Mike Kruger has just launched his own website and blog. Check it out! It has lots of excellent material already, and more to come no doubt.

While you’re at it, you should also pre-order his latest book, Canon Revisited. As far as I know, this is the first evangelical introduction to canonics to closely integrate the history of canon with the theology of canon. It will fill a conspicuous gap in the literature. It offers, in effect, what I would call an “evidential presuppositionalist” defense of the Protestant view of the New Testament canon.

Does Presuppositionalism Engage in Question-Begging?

The Gospel Coalition is running a series on methods in apologetics. The latest installment is “Questioning Presuppositionalism” by Dr. Paul Copan, who raises four criticisms of presuppositionalism, one of which is the old canard that presuppositionalists engage in fallacious circular reasoning. (I think all four are misguided in one way or another, but the other three will have to wait for now.) He writes:

First, it engages in question-begging — assuming what one wants to prove. It begins with the assumption that God exists, and then concludes that God exists. Such reasoning would get you an “F” in any logic class worthy of the name!

Dr. Copan is a gentleman and a scholar, so I’m sure he doesn’t realize quite how insulting this sounds to presuppositionalists! (For comparison, imagine someone claiming that evidentialists commit the fallacy of affirming the consequent because they use inductive inferences.) This criticism has been answered many times, so it’s disappointing to find it cropping up yet again (although perhaps presuppositionalists should take comfort from the fact that Dr. Copan doesn’t offer any new criticisms!). Even so, I’ll try to explain one more time why this complaint so badly misses the mark.

Why I Am Not a Panentheist

Michael Sudduth, a philosopher of religion at San Francisco State University, has caused quite a stir by announcing his departure from orthodox Christianity and conversion to Gaudiya Vaishnavism (a form of Vaishnava Vedanta Hinduism). Having known Michael for over a decade, and having had many profitable philosophical discussions with him, I was extremely grieved to read this announcement, although it didn’t come completely out of the blue. Some mutual friends had informed me of his increasing interest in Eastern religion and his gradually distancing himself from biblical Christianity. We had an email exchange last year when I raised some concerns (my last email, it turns out, was sent several days before his “profoundly moving religious experience of Krishna”) but it quickly fizzled out because Michael wasn’t ready at that time to set out his views in detail.

I’m not going to comment on his conversion testimony or on the complex personal experiences and circumstances that led to it (only some of which are mentioned in that testimony). However, I do want to remark on one particular statement:

Consequently, I now accept a panentheistic metaphysics in which the universe and human souls are, to put it roughly, in the being of God.

Antitheism Presupposes Theism (And So Does Every Other ‘Ism’)

By this rejection of God, agnosticism has embraced complete relativism. Yet this relativism must furnish a basis for the rejection of the absolute. Accordingly, the standard of self-contradiction taken for granted by antitheistic thought presupposes the absolute for its operation. Antitheism presupposes theism. One must stand upon the solid ground of theism to be an effective antitheist.

(Cornelius Van Til, A Survey of Christian Epistemology, p. xi)

“Antitheism presupposes theism” is one of Van Til’s best lines, because it captures in a nutshell the genius of presuppositional apologetics. It’s not merely that theism is true; it’s not merely that theism can be shown to be true; it’s that theism can be shown to be true by any attempt to prove it false. One can prove theism to be false only if, as a matter of fundamental metaphysical fact, theism is true — which is just to say that antitheism is self-defeating.

The Lord of Non-Contradiction

Philosophia Christi has kindly permitted me to post on my website a preprint of “The Lord of Non-Contradiction: An Argument for God from Logic”, which I co-authored with Greg Welty. I wrote the first version of the paper, but Greg did all the heavy lifting; the argument is indebted to the ideas he developed in his DPhil dissertation on theistic conceptual realism.

Logic

Here’s the abstract:

In this paper we offer a new argument for the existence of God. We contend that the laws of logic are metaphysically dependent on the existence of God, understood as a necessarily existent, personal, spiritual being; thus anyone who grants that there are laws of logic should also accept that there is a God. We argue that if our most natural intuitions about them are correct, and if they’re to play the role in our intellectual activities that we take them to play, then the laws of logic are best construed as necessarily existent thoughts — more specifically, as divine thoughts about divine thoughts. We conclude by highlighting some implications for both theistic arguments and antitheistic arguments.

While we don’t discuss Van Til or presuppositional apologetics in the paper, those so inclined will recognize this as a more robust exposition of a common presuppositionalist argument and they’ll also appreciate (I hope) the concluding remarks.

Dawkins is Disgusted

The Guardian has provided Richard Dawkins with a platform to explain why he won’t share a platform with Christian apologist William Lane Craig. Dawkins plays what he thinks is a trump card: the real reason he won’t publicly debate Craig is because — drumroll, please — Craig has defended the “genocides ordered by the God of the Old Testament.” It ought to be apparent to anyone who has compared Dawkins’ past debate performances with Craig’s (never mind their respective writings on the rationality of theism) that this explanation is, at best, a feeble rationalization. But that’s not the point I want to make in this post.

Dawkins, Disgusted

Dawkins’ piece reflects his trademark rhetorical devices — condescension, mockery, faux outrage, and a dash or two of genuine wit — but what stuck me most was the complete absence of any moral categories in his criticism of Craig and his views. Dawkins regards Craig’s views as ‘horrific’, ‘revolting’, ‘shocking’, and ‘deplorable’. But none of these descriptors function as objective moral evaluations of Craig or Craig’s God. In reality, they reflect little more than Dawkins’ feelings about Craig and Craig’s God (and the feelings of those who share Dawkins’ jaundiced outlook on the world).

I suppose this shouldn’t be surprising, given Dawkins’ published views on the nature of morality. For example, in The God Delusion he rejected and ridiculed the notion that there are moral absolutes. But if there are no moral absolutes, then there are no moral principles that absolutely rule out genocide. According to Dawkins’ moral outlook, then, genocide could be morally justified in some circumstances — just as late-term abortion is morally justified in some circumstances (as Dawkins apparently believes). Isn’t it therefore an open question whether the Old Testament ‘genocides’ were morally justified given the circumstances? Given Dawkins’ own premises, isn’t that question at least worthy of… debate? (I should state for the record that I don’t believe the destruction of the Canaanites was an instance of genocide; I’m just granting Dawkins’ characterization for the sake of argument.)

In the end, all Dawkins has really told us is that he won’t debate Craig because he finds Craig’s views personally offensive. It’s not that Craig’s views are unethical; it’s not that they’re immoral; it’s certainly not that they’re wicked or evil. It’s just that Dawkins finds them extremely distasteful. Dawkins is disgusted — and that’s all there is to it. Even if that were the real reason for his refusal to debate Craig, it would hardly be a compelling one. The only virtue of Dawkins’ dubious explanation, if it can be called a virtue, is its consistency with his moral nihilism.

Update: Here are some entertaining commentaries on Dawkins’ piece:
