A few people have asked me lately–what do I think of Jordan Peterson? Peterson is a Canadian psychologist who has written a book called 12 Rules for Life. He’s become very popular on YouTube and generated something of a following.

But it’s an old kind of philosophy which dates back to the 19th century and takes its inspiration from Soren Kierkegaard. It’s called “Christian Existentialism”. Here’s how it works.
