Any truth claim negates every proposition that denies it. This is the logic of antithesis… For instance, if Jesus is God incarnate, then he is not (1) a mere prophet of Allah (Islam), (2) a misguided reformer (Judaism), (3) an avatar of Brahman (Hinduism), (4) a manifestation of God (Baha’i Faith), (5) a God-realized guru (New Age), (6) an inspired but not divine social prophet (theological liberalism), and so on.

    Hello Dr. Samples,

    I am John Rakshith from India. Sometime back I listened to some radio broadcast series on Reasons To Believe on Apologetics. It came interesting that you were convinced of inference to the best explanation theory as opposed to other methods and in particular, presuppositionalism. May I ask you some reasons for which you are an advocate of it. Also, during the talk you said that you were formerly a presuppositionalist. So what were the reasons that caused you to re-think (if you may) on the method of defending the faith? Thank you for your response!

    My personal approach to apologetics method has evolved over the years. I was first an evidentialist (Martin, Montgomery, and McDowell), then a classicalist (Geisler, Craig), but then I was influenced by both presuppositionalism (Bahnsen and Frame) and by the new Reformed epistemology (Plantinga).

    Over the last ten years I’m probably best identified as utilizing a Cumulative Case approach (abductive reasoning: God as the “best explanation” for reality [Paul Copan], see the book Five Views of Apologetics edited by Steve Cowan). I view abductive reasoning as a normal and natural way that people reason, including detectives, historians, lawyers, scientists, doctors, and mechanics. Here’s a link to an article where I briefly explore the topic:

    Overall I draw upon elements from various apologetics methodologies and I think the schools have a lot of common ground.

    Best regards in Christ.
