Comparison With Other Schools of Apologetics

Presuppositionalists contrast their approach with the other schools of Christian apologetics by describing the others as assuming that the world is intelligible apart from belief in the existence of God and then arguing on purportedly neutral grounds to support trusting the Christian Scriptures and the existence of God. Specifically, presuppositionalists describe Thomistic (also "Traditional" or "Classical") apologetics as concentrating on the first aspect of apologetics with its logical proofs for the existence of God, simply assuming common ground with the non-Christian and utilizing a piece-by-piece methodology. In this scheme, the common foundation of neutral brute facts leads to a generic concept of deity, then to the various characteristics of the Christian God as revealed in Scripture, and so forth. Piece-by-piece, Christian theology is built up from a neutral common ground.

Presuppositionalists assert that many of the classical arguments are logically fallacious, or don't prove enough, when used as arguments to prove the existence or character of God. They criticize both the assumption of neutrality and the "block house" or "piecemeal" method for failing to start at the level of the controlling beliefs of worldviews and implicitly allowing non-Christian assumptions from the start, thereby trying to build a Christian "house" on a non-Christian "foundation". Evidentialists demur from this assessment, claiming that presuppositionalism amounts to fideism because it rejects a neutral starting point for reasoning between the Christian and non-Christian.

The conclusion of evidential apologetics is that the Bible is probably more accurate about what it reports than not, thus the whole of Biblical revelation is probably true, and where we don't have absolute certainty we must accept the most probable theory. The goal of presuppositional apologetics on the other hand, is to argue that the assumptions and actions of non-Christians require them to believe certain things about God, man and the world which they claim they do not believe. This type of argument is technically called a reductio ad absurdum in that it attempts to reduce the opposition to holding an absurd, i.e. contradictory position; in this case, both believing in facts of Christian revelation (in practice) and denying them (in word). So in essence, evidential apologetics attempts to build from a common starting point in neutral facts, while presuppositional apologetics attempts to claim all facts for the Christian worldview as the only framework in which they are intelligible.
