Hello PB, If you do any searches on this site for my posts, you will find that at times I have been critical of both Clarkian and Van Tillian presuppositionalism. My criticisms mainly lie in areas of both camps tending to claim more for their method and argument than is warranted, and not being entirely accurate in their criticisms of other apologetic methods. Because of some of the strong rhetoric that can occur in these discussions one might get the impression that I am against presuppositional apologetics. This would be a mistake. Below is a link to my recreation of a formal debate I participated in a number of years ago. I specifically set out to use an argument that I learned from Greg Bahnsen, and was my attempt to honor the Van Tillian approach. (Still, I am partial to Clark. ) Although, it may not be a good illustration of the apologetic method, it is an illustration of the method, nonetheless. Perhaps, someone might find it useful. Observations and criticisms are welcome. Does God Exist? Sincerely, Brian Edited to Add: Thanks to Brian Eschen for pointing out a number of typos. They have been fixed.
