"Essence of rationality is that you can be wrong. Unambiguously, unarguably, irrefutably, utterly wrong. Without that: no rationality, no systematicity, no modern world. STEM classes give you the felt experience of being wrong may times per day. It is only when that sinks in your bones that you can know what it means to do something correctly. “Doing it correctly” is systematic rationality, which is what keeps airplanes in the air & electric lights on" - David Chapman
