About This Episode In this episode of Notions of Progress — the first of a two-part solo series — we ask a deceptively simple question: were the ancient Greek Sophists the original enlightenment-like thinkers of human progress? These were the famous and sought-after educators of fifth-century Athens. They charged fees, itinerant, and claimed that human excellence could be developed, not just inherited. For that, they were called sophists — a word that still, today,carries a negative connotation.
Drawing on W.K.C. Guthrie’s A History of Greek Philosophy, Rachel Barney’s scholarship on technê and Sophistic thought, Joshua Billings’ work on the fifth-century enlightenment, and the authentic fragments of Protagoras himself, this episode examines whether the Sophists represent a genuine ‘enlightenment’ movement — one defined by empirical inquiry and skepticism toward inherited authority, and a theory of civilizational progress through techne,teachable skills.
The episode includes five key Greek terms that carry the conceptual weight of the Sophists’ argument, profiles the four major figures of the movement, and closes with Protagoras’s great myth of human origins from Plato’s Protagoras.
Five Important Terms Sophistês (so-fis-TAYS): Literally “one who makes people wise.” A professional teacher of practical wisdom and civic skill in 5th-century Athens. Technê (tek-NAY): A Greek word with no exact English equivalent. It equates to systematic, teachable skills — but more than technique. Technê transforms its practitioner. The Sophists believed technê was a key driver of human progress. Aretê (ah-reh-TAY): Excellence, or virtue. For the Sophists, aretê was not a fixed gift of birth or divine favor — it was something that could be taught. Nomos (NOH-moss): Law, custom, convention. What human beings have established through agreement and institutions. Physis (FEW-sis): Nature, or natural reality. The tension between nomos and physis — between convention and nature — is one of the defining intellectual controversies of the fifth century as it informed one’s belief in acquired vs inherited power
Major Themes How the word “sophist” went from a term of respect to an insult, and why it matters for reading the historical record George Grote’s 19th-century rehabilitation of the Sophists, and Eduard Zeller’s influential counter-verdict — a scholarly debate that still shapes how ancient philosophy is taught Joshua Billings on the fifth-century enlightenment: three characteristic modes of Sophistic thought — empirical research, arguing both sides, and critical reasoning about divine causality The four major figures: Protagoras, Gorgias, Prodicus, and Hippias — what distinguished each of them and what they shared Protagoras’s great myth from the Protagoras dialogue: a three-stage narrative of human progress from vulnerable animals to skilled craftsmen to citizens capable of governing themselves Whether the Sophists represent the first systematic theory of progress through human agency — and what that question means for the larger arc of this podcast
Fascinating Historical Insights Aristophanes’ The Clouds as hostile source material The earliest surviving satire of Sophistic teaching is not a philosophical argument — it’s a comedy. In The Clouds (423 BCE), Aristophanes portrays Socrates running a “Thinkery” where students learn to make the weaker argument defeat the stronger. Scholars like W.K.C. Guthrie treat this as evidence of public anxiety about Sophistic education, not as an accurate description of what the Sophists actually taught. Protagoras was reportedly tried, banished, and his books burned in the Athenian agora. He was tried for impiety, expelled from Athens, and — according to ancient sources — his books were gathered and burned publicly in the agora. The man who said human beings were “the measure of all things” was destroyed by the very democratic city that prided itself on open debate. His books have not survived.

In this third and final part of the conversation, Marxist economist Michael Roberts brings the argument of his 2016 book The Long Depression into the present. He begins with the view that the system works as long as decisions are good, which he finds unconvincing: a system that produces for profit, he argues, delivers both vitality and grotesque inequality, and cannot continue as it is. He describes a generation now worse off than its parents and presents the postwar golden age as the exception, a period when profitability was high enough for capitalism to make concessions. Turning to the current cycle, Roberts considers whether the long depression that followed 2008 may be ending, whether AI could lift profitability for a time, and why he expects the law of profitability to reassert itself, possibly in the 2030s or later. He answers economist Robert J. Gordon on stagnation and Thomas Piketty on taxing billionaires, and closes on three futures: a renewed expansion, a longer stagnation, or, if working people do not change the system, fascist and military regimes and what he calls barbarism, drawing on the fall of Rome.

In this second of a three-part conversation, Marxist economist Michael Roberts takes the central claim from Part One — that the 2008 crash opened a long depression — back to the two historical cases on which his 2016 book The Long Depression rests. He begins with the 1870s, answering the Austrian-school argument that no depression took place and a rival monetary explanation tied to the gold standard; his reply draws on the data for Britain, the hegemonic economy of the period. He then sets out the mechanism he takes from the third volume of Marx’s Capital: capitalists invest only when it is profitable, and competition drives them to invest ever more in machinery relative to labor, which Roberts argues pulls the rate of profit down over time, held back for a while by counteracting tendencies. The same pattern, on his account, ran beneath the stock-market boom of the late 1920s and the slump of the 1930s. The episode closes on the rival crisis theories Roberts contests — policy error, unregulated finance, underconsumption, and overproduction — and on his case for profitability as the driver of booms and slumps alike.

In this first of a three-part conversation, Marxist economist Michael Roberts joins Notions of Progress to lay out the central argument of his 2016 book The Long Depression: that the 2008 financial crash was not an ordinary recession, but the opening of a longer structural depression driven by capitalism’s own tendency toward falling profitability. Before getting there, Roberts traces his own path — from a Marxist conversion as a student to a three-decade career as an economist inside the City of London, a combination he treats as complementary rather than contradictory. He then lays out a materialist conception of history underlying his economics: social change driven by who owns and controls production, not by ideas or political leadership taken on their own. Capitalism, on his account, is real progress — rising productivity, rising living standards — and, at the same time, structurally exploitative and radically unequal. The episode closes on the specific technical definition of a “depression” that Parts Two and Three will test against the historical record: not simply a downturn, but one whose recovery never returns to the prior trend line.

This episode closes out a three-part conversation with Gavin Mueller (University of Amsterdam), author of Breaking Things at Work. In Part 2, Mueller traced Marx's own ambivalence toward machinery through the split between orthodox and heterodox Marxism, Frederick Taylor's theory of workplace control, the Technocracy Movement, and Norbert Wiener's early warnings to organized labor about automation. In this final part, Mueller brings that history into the present. The conversation moves from Shoshana Zuboff's early sociological research inside computerized factories to her later, better-known work on surveillance capitalism, and from there into Mueller's own reading of artificial intelligence: the argument that AI systems depend on training data gathered without most people's consent, the concept of cognitive offloading, and the rapidly growing, cross-partisan resistance movement against AI data centers. Mueller closes with what he calls Luddism's real legacy — not a rejection of the future, but the insistence that a different one is still possible.
In Episode 17, Gavin Mueller (University of Amsterdam) traced the Luddites back to the guild economy of England's Midlands. In this second installment of a three-part conversation, Mueller follows that struggle into the twentieth century: Karl Marx's own ambivalence toward machinery, and the split between Karl Kautsky's “orthodox” Marxism — which treated capitalist technology as a scientifically inevitable path to socialism — and the workers' movements that resisted that framing directly on the shop floor. Mueller traces Frederick Winslow Taylor's “scientific management” as, above all, a theory of control rather than efficiency; the short-lived but influential Technocracy Movement's vision of automation as an unstoppable social force; and mathematician Norbert Wiener's cybernetics, including his largely unheeded 1949 letter warning UAW president Walter Reuther that automation posed a genuine threat to organized labor. The episode closes on how that warning intersected with civil rights-era debates about automation's disproportionate impact on Black workers. As with the whole series, the through-line is not a settled verdict on technology and progress, but the recurring argument over whether machines serve human ends or reshape them.
