Aristotle asks a question most modern philosophy has stopped asking: what is a human being for? In Part 1 of this two-part episode, Marshall works through Aristotle's argument that every activity aims at some good — and that there is a highest good, eudaimonia, that makes the others intelligible. Drawing on Alasdair MacIntyre's reading in After Virtue and Philippa Foot's Natural Goodness, the episode traces what telos means, why it is grounded in nature rather than imposed from outside, and why a critical distinction — between how we come to know things and what we fundamentally are — is essential before the argument can proceed.

The episode closes with Karl Popper's charge from The Open Society and Its Enemies: that Aristotle's account of fixed ends generates the intellectual architecture of the closed society. That charge is not answered in Part 1. It is posed as the question Part 2 must address.

KEY TOPICS COVERED
- The open/closed systems framework introduced by Matt Ehret (E11–E13) and what it raises for Aristotelian ethics
- Aristotle's foundational observation: every activity aims at some good
- Eudaimonia — flourishing as a form of life, not a feeling to be produced
- MacIntyre's reading of the virtues as partly constitutive of the good life, not merely instrumental to it
- Telos as the internal logic of a natural form of life — not a blueprint imposed from outside
- Philippa Foot's Natural Goodness: how evaluations of living things are grounded in natural facts
- The tabula rasa distinction: Aristotle's account of how we come to know things vs. his account of what we are
- Popper's charge: that Aristotle's account of fixed ends generates the intellectual architecture of the closed society
- Phronesis — practical wisdom — named and seeded for Part 2 and the Ansar episode

ABOUT NOTIONS OF PROGRESS
Notions of Progress is a podcast tracing ideas of progress from antiquity to the age of AI. Hosted by Marshall Madow — independent researcher and scholar-curator, MA in History (Cambridge), MSc in Complexity Science and Leadership (Oxford, Saïd Business School) — the series examines how the idea that humanity advances through time toward something better has been understood, contested, and reimagined across millennia. Guest episodes bring scholars and thinkers who argue from within intellectual traditions. Solo episodes follow the chronological spine from the ancient Greeks through the Hellenistic schools, the Roman world, and toward the age of artificial intelligence.
