Greg Welty recently wrote a book on Alvin Plantinga in the "Great Thinkers" series. Alvin Plantinga is a renowned Christian philosopher whom you should be familiar with. He was at the forefront of a Christian renaissance in academic philosophy in the latter half of the 20th century. Welty's book is a great short introduction to Plantinga's work. One place where Adam disagrees with Plantinga is on the idea of "Reformed Epistemology." Some descriptions of Reformed Epistemology seem to look down too much on human reason. While we certainly don't want to downplay or dismiss the vital work of the Holy Spirit, we don't want to settle for basing everything on feelings or intuitions either. In his book Warranted Christian Belief, Plantinga seems to dismiss the idea that philosophy can be useful in determining if Christianity is true, and Adam thinks he is incorrect to do that.

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.

Many Christians these days use the term "Christian worldview" to describe their beliefs. Having a "Christian worldview" is usually deemed very important in many Christian circles. But is the term "worldview" a word that Christians should use to describe their beliefs? This term actually came out of postmodern philosophy and has a history of framing all truth claims as merely subjective statements rather than objective facts about the world. In this context, someone's "worldview" was just the way that he or she preferred to view the world rather than a term describing beliefs that apply objectively to everybody, regardless of their subjective "view" or "worldview."
