The presuppositionalist defends the logical consistency of scripture and refutes claims made from other disciplines used by unbelievers to attempt to contradict scripture, but none of these things are used as "proofs" that the bible is God's Word. Hence such defenses can be consistent with presuppositionalism if used correctly.
