He said yes to a random LinkedIn message about lifting weights and burning fat — and somehow ended up in a nearly hour-long conversation about game theory, thermodynamics, and why he came back to Christianity after years of calling himself an atheist. Philosophical Philip lives in Pretoria, South Africa, and thinks about morality the way most people think about their to-do list.

We connected with Philip after reaching out for fitness advice. Turns out he's a serial "yes man," and this podcast was one more yes.

We cover a career path that's gone from genetics to startup CTO to insurance actuary to financial analyst, twenty years of obsessing over the evolutionary origins of morality, a Richard Dawkins book report he faked in university, becoming a father and realizing atheism gave him "no tangible values," a family incident that pushed him back toward Christian principles, and a real-time theological debate with Rush over whether happiness comes from controlling your world or surrendering control to God.
