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.

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.

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.

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?

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!
