On their Theory of Anything podcast, Bruce Nielson and Peter Johansen discuss epistemology with me. One big question we take up: Before doing high-level philosophy of science—logic, math, experiment design, theory-formation—how important is it to have good accounts of base-level cognition—perception, conception, proposition-formation? Another: What are the similarities and differences between Critical Rationalism (launched by Karl Popper) and Objectivism (launched by Ayn Rand)?
