Vincent Cheung has further added to his offensive by giving suggestions to those who oppose Van Tillian apologetics (now if only he would give examples of himself doing these things!):

* Obtain at least two complete presentations of pseudo-presuppositionalism. Use only the best examples from its leading and most trusted proponents. Read them, and then refute them. In the process, consider what they say about sensation, intuition, induction, and science both before and after they assert presuppositionalism as the solution. Is their so-called presuppositionalism able to answer the very arguments that they use against evidentialism? Or does it crumble under the same criticisms? Explain and demonstrate your conclusions.
* Locate either a written debate or the transcript of an oral debate between an atheist and a pseudo-presuppositionalist. Preferably, both of them should be the most highly regarded and established representatives in their fields.
You will find that the atheist loses the debate. At the same time, since his opponent is a pseudo-presuppositionalist, you will find that his defeat is not as decisive as you might prefer or expect. You might find that the believer allows his opponent to get away with many false assumptions. This is because, being a pseudo-presuppositionalist, he also shares many of these anti-biblical assumptions. In fact, in some contexts, such as when he attempts to refute biblical rationalism, he might admit that these anti-biblical assumptions even epistemologically precede his own Christian presuppositions, that he requires them to know about Christianity in the first place.
Since atheism is so easy to defeat, the Christian can always have the upper hand, but the weakness and inconsistency that you perceive come from the internal contradictions of pseudo-presuppositionalism. With this understanding, go through the debate again and devise better arguments and refutations than those offered by pseudo-presuppositionalism.
Then, turn your attention to the pseudo-presuppositionalist and refute him. If he is truly a pseudo-presuppositionalist, you should be able to refute him just as quickly and thoroughly as you do the atheist. However, the atheist is not able to perform such a refutation since he is bound by his own anti-biblical presuppositions, the same ones that the pseudo-presuppositionalist affirms. Once you abandon these false principles, you are able to refute both sides with equal ease. That said, an unbeliever who is willing to sacrifice his own claim to rationality can push toward mutual destruction when debating a pseudo-presuppositionalist who shares the same anti-biblical assumptions.
