I recently watched (or rather listened to) the debate last December between Jeffrey Jay Lowder and Frank Turek on whether naturalism or theism “better explains reality”:
Overall it was one of the better theist-atheist debates I’ve encountered, and I would recommend watching it. The two opponents were intelligent, well-spoken, respectful, experienced, and focused on the issues. I’m not going to evaluate all the arguments in the debate or make a judgment about who ‘won’ the debate (it depends which criteria you apply). I’m just going to make some very general comments about the strengths and weaknesses of the presentations.
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.
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.
