My understanding is that Peterson has suffered some health setbacks (if I am wrong about this, I apologize), and, therefore, he has released his videos in a more drawn-out manner than originally planned.

The conversation was focused on Austrian Economics.  Peterson asked some probing questions – after things that are easy to take for granted if one is bent in a free-market direction.  But necessary questions if one is after opening a conversation with those not so inclined.

A couple of things struck me about the conversation.  First, as was seen by many who are familiar both with Austrian Economics and Peterson: although he has had no previous formal exposure to this school of economics, his fields of study and focus made it easy (natural) for him to grasp the points Murphy was making.
