Can ingenuity alone advance civilization — or does it require something technical skill cannot replace?
In this clip from Episode 5, Prof. W.K.C. Guthrie, Prof. Rachel Barney, and Prof. Mauro Bonazzi guide us through Protagoras’ Myth of Prometheus — and what it actually argues. The standard reading treats the myth as a celebration of technē, the practical skills Prometheus steals from the gods, as the engine of human progress. But Bonazzi reads the myth more carefully: Phase two, the arrival of technical skill, is a failure if it stands alone. The myth’s real weight, Guthrie argues, falls on Zeus’s second intervention — the democratic distribution of justice and shame to all citizens, not just the few. Barney connects this directly to Periclean democratic practice, suggesting Protagoras was offering a theoretical foundation, not abstract philosophy. Yet Guthrie, Barney, and Billings all identify the wound the Sophists could not close: if justice is only human convention — nomos — what prevents someone from arguing that convention is merely a mask for power?
That question, Barney argues, is the one Plato inherited — and the one that drives the argument of the Republic.
