Edgar on Van Til

You might know that P&R have been publishing new editions of Cornelius Van Til’s major works. You might also know that those new editions have introductions and explanatory notes by WTS professors William Edgar and K. Scott Oliphint.

You might not know, however, that a couple of Edgar’s introductory essays are fully contained in the free samples of those books available on the Westminster Bookstore website:

A Selection of Presuppositional Arguments

One criticism of presuppositional apologetics is that its advocates rarely if ever offer serious arguments for their distinctive claims (e.g., the claim that our ability to reason presupposes the existence of God). The criticism is overstated, but there is a measure of truth to it. I count myself a presuppositionalist, but I’ve been frustrated in the past by presuppositionalists who seem to imagine that declaring what Van Til’s “transcendental argument” purports to demonstrate is tantamount to actually making that demonstration. Simply asserting that “without God you can’t prove anything at all” or that “your very ability to reason presupposes the existence of God” does nothing whatsoever to explain why those weighty assertions should be believed. Likewise for the failure of non-Christians to answer questions asking them to account for their ability to reason, to know truths about the world, to make meaningful moral judgments, etc., in terms of their own worldviews. Questions cannot substitute for arguments, no matter how pointed those questions may be.

So it’s important for presuppositionalists to present arguments in support of their claims, and to ensure their critics are aware of those arguments so that they can be critically evaluated. In that spirit, I thought it would be useful to gather in one place my own presuppositional arguments, as well as my attempts to explain or reconstruct the arguments of other presuppositionalists:

In addition, my book Why Should I Believe Christianity? offers a broadly presuppositional (and evidential!) case for the biblical Christian worldview.

Can Life Have Meaning Without God?

The Atheist’s Guide to Intellectual Suicide

Having been recently promoted to associate professor, I was invited to give a short lecture at our Fall convocation service last week. The audio of the lecture (“The Atheist’s Guide to Intellectual Suicide”) is now available on iTunes U.

On a closely related note, check out these good thoughts by my colleague Mike Kruger on the current state of public debate over moral issues.

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.

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.


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.

TAG and Epistemic Certainty

A commenter asks why I don’t endorse the claim that the transcendental argument for the existence of God (TAG) gives us epistemic certainty (which I take to mean that the argument delivers a conclusion that has maximal epistemic warrant and could not be rationally doubted). After all, if TAG proves Christian theism “by the impossibility of the contrary”, as many of its advocates have claimed, wouldn’t it follow that TAG’s conclusion is epistemically certain?

Geerhardus Vos’ Reformed Dogmatics

Most readers of this blog will know that I’m a big fan of the brilliant Reformed apologist Cornelius Van Til. (Proof: I drink coffee out of one of these.) Most readers of Van Til will know that he was a big fan of the brilliant Reformed biblical theologian Geerhardus Vos, who was one of his professors at Princeton Seminary. Van Til described Vos as “the greatest pedagogue I ever sat under.”

I’m not sure whether the big-fan-of relation is transitive, but it seems more than fitting to pass on word from Phil Gons that Logos are planning a full English translation of Vos’ Gereformeerde Dogmatiek. However, the project is contingent on there being sufficient interest. Go here for more information, including how to pre-order at a locked-in low price.

No Dilemma for the Proponent of the Transcendental Argument

The editor of Philosophia Christi has kindly permitted me to post on my website a preprint of my article “No Dilemma for the Proponent of the Transcendental Argument: A Response to David Reiter”. The article is scheduled to appear in the Summer 2011 issue along with a short rejoinder from David. It was a profitable exchange, and it’s gratifying that Philosophia Christi considers TAG to be worthy of critical scholarly discussion. Van Tilians should also be thankful for sympathetic, well-informed critics like David. May his tribe increase!
