Presuppositional apologetics

Presuppositional apologetics, shortened to presuppositionalism, is an epistemological school of Christian apologetics that examines the presuppositions at the basis of various worldviews, and invites comparison and contrast between the results of those presuppositions. It claims that apart from presuppositions, one could not make sense of any human experience, and that there can be no set of neutral assumptions from which a Christian can reason with a non-Christian.
