I transcribed his podcast, episode 22, starting 4min in:
And the fact is that I'm not an epistemologist, let alone a technical one. The older I get, I realize I'm not a philosopher, and never really was. My real interest in life is cultural analysis. How does philosophy influence, for instance, the rise of Hitler or kind of educational system we have or great plays ... that's always been the kind of thing I've done. The only exception is OPAR, which was pure philosophy, but that was simply paying off a debt. I had to do that to Ayn Rand in exchange for what she had, you know, taught me for 30 years. But other than that I never would wanna write or really lecture on philosophy. I don't see that there's anything wrong with that, but that is just not what I do.So OPAR isn't Peikoff's kind of thing. Ayn Rand couldn't find an heir who actually wanted to be a philosopher. Ayn Rand couldn't find a better student to teach philosophy to than a non-philosopher.
It's not that Peikoff tried and failed. It's not that he values philosophy, like Objectivism, above all else, but isn't good enough at it. He doesn't even care about it like that.
How can a man like this be any kind of leader in a philosophy community?
How can any self-proclaimed non-philosopher consider themselves an Objectivist? Doesn't he know what Objectivism says philosophy's role in life is? Everyone should be a philosopher. Everyone needs philosophy. Everyone has a philosophy. The question is just how interested they are in thinking it through and getting their philosophy right.
Update 2021-12-09: I think my last paragraph is unfair. I withdraw it. Peikoff was saying he didn't want to study philosophy in detail, or write or teach it, not that he didn't want to have philosophy in his life. What he said can be charitably interpretted as him caring about philosophy enough to want to learn and understand Objectivism and use it in his life, and just excluding optional advanced stuff. That makes him an inappropriate Objectivist or philosophical leader but not a bad person or non-Objectivist. In other words, he wasn't rejecting philosophy; he just wanted something else for his profession.
