Meet Aaron Stupple, a practicing physician, a father of five, the co-author (with Logan Chipkin) of The Sovereign Child, and a co-founder of the Conjecture Institute. In his house there are no rules: no fixed bedtimes, no forced meals, no school, screens whenever. But this is not an hour about screens and sugar. Aaron has had that debate everywhere else. This is the conversation behind the book. We start where nobody else does: with the kind of child Aaron himself was, and a father who told him "it's us against school." From there we get into the forgotten philosophy that rewired his life, Karl Popper and David Deutsch's critical rationalism, and why he thinks the whole parenting question, "where do I draw the line?", is simply the wrong question. He explains how knowledge grows the way species evolve, by guessing and getting shot down. He makes the case that willpower and self-discipline are a quiet form of bullying yourself, that grit is nonsense, and that a habit is not a ditch carved in your brain but a reason that a better reason can replace in an instant. He tells me why he answers his cruelest critics one by one: "they're working for you, for free." And in the most honest moment of the hour, he admits what he still cannot figure out. This is one of those RareErth conversations that leaves you lighter than it found you.
