Abstract

Public presuppositions suffice in arguments for Christianity, without needing controversial presuppositions such as the authority of the Bible. Necessary and sufficient presuppositions can be derived from rudimentary common sense, which is shared by Christianity and virtually all other worldviews. These claims are defended against three problematic ideas in contemporary Christian apologetics concerning circular reasoning, starting points, and neutral rationality. Public presuppositions are discussed in the contexts of both evidential and presuppositional apologetics.
