In this week's episode of Quiddity, the CiRCE podcast and the audio companion to this website, David Kern chats with author and culture critic Brett McCracken, whose new bookGray Matters: Navigating the Space Between Legalism and Liberty, came out earlier this month from Baker Books. They talk about why he was motivated to write this book, how to cultivate cultural discernment in young people, and why so many recent books have challenged common Chrisitian conceptions of cultural engagement.
