Once upon a time, not so long ago, I was a Presuppositionalist. I’ve discussed this briefly before, but having grown weary and suspect of the weaknesses of apologetic methods like Thomistic arguments and evidentialism, I turned to the seemingly-unassailable circularity offered by this “epistemology.” I just used scare quotes there because Presuppositionalism probably isn’t as much of an epistemology as it is an apologetic method (if it’s even that). The basic claim of Presuppositionalism is that the Christian understanding of reality is the only internally consistent worldview and that the propositions contained in the Protestant Bible, and implicitly theWestminsterian interpretation of those propositions, are to be taken axiomatically. All other worldviews will fail the internal scrutiny of a reductio ad absurdum.
