Johann is the author of Chasing the Scream and Lost Connections -- both of which are largely about the traumas created by trying to live in a pathogenic society. He's a brilliant writer and conversationalist. In the first part of this podcast, we're in his hotel room in Beverly Hills (Thanks, Rupert Murdock!). The second part is in my car, headed south on the 405. I had a great time hanging with Johann, and hope you enjoy it, too.

Jamie was a prominent stand-up comic before he drifted into political commentary, eventually becoming a leading voice among the social justice warrior crowd, with his radio show (Citizen Radio). That ended when he was accused of "inappropriate behavior" and he suddenly found himself the target of the same kinds of uncritical condemnation he'd directed at others. It's been a wild ride, but he's back on his feet, and wiser for it.

David Beckingham is a Canadian musician who drove down to Oregon to catch the eclipse with me this summer. Afterwards, we hung out in the woods and on the slopes of Mount Hood for a few days, where we recorded this podcast.

Charlotte McKinney is a sweet, kind, smart young woman who happens to occupy the sort of body that many men would sell their soul to get close to. To say that's been a mixed blessing for her is to put it mildly. She's been featured in Super Bowl commercials, on the cover of GQ, in a slew of ads for Guess, and everywhere else sexy women's images are used to sell stuff. In this conversation, we get behind the image and meet the woman who lives there.
