Yes, Harris very effectively pinned him down on the issue of truth, and Peterson's claims that there is a distinction between "objective truth" and "mythical, archetypal truth that you had better bloody well believe or you will fail to get the gold from the dragon and in turn fail to propagate as a species and end up in Hell, or as Jung might say..."which is just as true as the other truth.
Harris showed time and again that Peterson's second idea of "truth" could be called "wisdom" and that various works of literature, not only Biblical stories (in fact, maybe to a lesser extent than, say, Shakespeare), have elements of wisdom to us, but they are
NOT true!
Harris comes up with a good analogy and that is the wisdom that there is no such thing as an unloaded gun. It's a very good way to live, but it isn't literally true.
My suspicion has always been that Peterson wants his interlocutors to say something like, "Okay, you're right, those stories do help me fulfill my Jungian archetypal hero's journey therefore I will accept the word true! And the Bible is one of those so it is true!"
And the big reveal for Peterson is, "Aha! So you do accept the truth of religion!" or some such lame conclusion.
Anyway, I found a couple more clips. Here's one which I mentioned earlier where Peterson is talking about how he is religious with Rogan. For some reason, I had remembered it as him saying he was an Orthodox Christian. Maybe he does later, I am not that interested in listening on. But it is him "reconciling" being scientific and a "deeply religious person". To be honest, most of what he then goes on to say is more word salad for me. Rogan seems to be drinking it all in with a "whoah, blows my mind" expression, and the You Tube comments are full of people who think Peterson is their "Lord":
