What happens to an ethics built on belonging to a city once that city stops being able to protect anyone?

This episode opens the Hellenistic arc of Notions of Progress with one of the strangest and most memorable answers: Diogenes of Sinope, a philosopher who lived in a discarded wine jar, told Alexander the Great to step out of his sunlight, and built an idea of progress around needing nothing from the city at all — only membership in a community with no borders.

KEY TOPICS COVERED
- How Philip and Alexander's conquests ended organized Greek political independence
- Historian F. W. Walbank on the shift from accountable Macedonian kingship to personal, unaccountable rule

ABOUT NOTIONS OF PROGRESS
Notions of Progress is a podcast tracing how the idea of progress has been understood, contested, and reimagined from antiquity to the age of artificial intelligence. Marshall Madow, an independent researcher and the show's host and scholar-curator, holds an MA in History from Cambridge University, where his thesis examined Georges Sorel's epistemology of myth, and an MSc from Oxford University's Saïd Business School in Complexity Science and Leadership. Rather than prescribing a position, the podcast surfaces scholarly debate — examining how thinkers from Hesiod to Hayek, from Plato to contemporary philosophers of technology, have understood what it means for humanity to move forward, at what cost, for whom, and by whose definition.
