In researching, reading, and thinking about writing a book about keeping my kids Christian, I was kind of surprised to discover how important questions of epistemology began to emerge. I even decided to write an entire chapter on epistemology—in a book on raising kids! I can understand why a lot of Christians would think that’s a bit nutty, in many cases because they wouldn’t even know what epistemology is. I’m hoping in some small way that my book might help change that. Every Christian in our postmodern, relativistic, secular age needs to know not only what epistemology is, but how important are the implications for their faith.
Simply, epistemology is the study of how we know what we know, and it has been vigorously debated among philosophers in Western civilization since at least Rene Descartes (1596-1650). The reason religious faith is so problematic in the modern West is because skepticism about metaphysical ideas and historical facts is the default epistemology of the culture. Which is why I was so surprised when I saw an article at the reliably liberal and secular NPR website titled, “Skepticism about Skepticism.” I instantly thought of a quote by C.S. Lewis in his book Christian Reflections (p. 164)
