Similarities Between Postmodernism and Presuppositional Apologetics

It may be surprising to hear that postmodernism and presuppositionalism could be similar. Postmodernism is a philosophy that, among other things, is very committed to the idea that truth is relative in some sense. Presuppositionalism is the idea that we should start doing apologetics by assuming (or presupposing) that God exists and the Bible is His Word. So, how could these two ideas be related? Both postmodernism and presuppositionalism were overreactions to philosophical modernism. Both movements tended to downplay the importance of using reason in forming our beliefs and instead focused on other means, such as our inner feelings (postmodernism) or blind faith (presuppositionalism). James K. A. Smith is an example of a presuppositionalist who has recognized and even promoted this connection.
