 From Newbigin's perspective, western cultures, particularly modern scientific cultures, had uncritically come to believe in objective knowledge that was unaffected by faith-based axiomatic presuppositions.Newbigin challenged these ideas of neutrality and also the closely related discussion concerning the distinction between facts and values, both of which emerged from the Enlightenment.It was during this time that he wrote two of his most important works, "Foolishness to the Greeks" and "The Gospel in a Pluralist Society" in which the strong influence of thinkers such as Alasdair MacIntyre and Michael Polanyi is apparent.
