Mark Meynell is a minister at All Soul's, London. He loves Christ. He loves culture. Listen to these three really useful talks for an overview into postmodernism and a fauré into our current culture's mindset.
Even better than the real thing - a day seminar seeking to understand Postmodernism and how it affects Christians (recorded 2006)
Marcus Honeysett used to be UCCF's London team leader. He's had much insight into the student world and has written a very helpful book: Meltdown: Making sense of a culture in Crisis. Marcus goes through the various academic theories that have underpinned postmodernism, and how they have been translated into wider society. Each chapter takes a theory at a time (sometimes it's quite heavy going, but worth reading if you really want to grapple with the issue). He then gives really helpful case studies at the end of each section, challenging us to think through the implications of believing, or not believing the postmodernist claims. A brilliant book to read in a group and discuss together.
