Plato vs. the Sophists: The Allegory of the Cave As His Answer On Progress | Ep. 6 pt 1
Notions of ProgressShow Notes
In this episode of Notions of Progress — the first of a two-part examination of Plato — we ask what happens to the Sophists’ theory of progress once Plato is done with it. The Sophists had argued that human beings advance through the accumulation of teachable skill: collectively, cumulatively, and through the civic power of persuasion. Plato systematically dismantled each of those claims. This episode traces the first two dimensions of that dismantling through two of the most consequential passages in the history of Western philosophy.
The first is the Allegory of the Cave (Republic Book VII, 514a–521b). The second is the doctrine of recollection, or anamnesis, introduced through the slave boy demonstration in the Meno (80a–86c). Taken together, these passages make a radical argument: genuine knowledge is not built up from experience, it is recovered from what the soul already contains. Progress, for Plato, is not horizontal accumulation — it is vertical ascent toward the eternal Forms, an ascent that is individual, not collective, and philosophical, not technical.
Drawing on W.K.C. Guthrie’s A History of Greek Philosophy, Julia Annas’s An Introduction to Plato’s Republic, and David Sedley’s scholarship on the Forms and philosophical education, this episode opens the question of whether Plato’s vision constitutes a theory of progress at all — or something altogether different.
Five Important Terms• Paideia (pie-DAY-ah): Formation, or the cultivation of the soul. For Plato, paideia is not the transmission of information but the turning of the whole person — their desires, habits, and perceptions — toward the Good. The Cave allegory is, among other things, an account of what genuine paideia requires. • Anamnesis (ah-nam-NAY-sis): Recollection. Plato’s doctrine, introduced in the Meno, that the soul does not learn new things but recovers what it already knew before birth. If anamnesis is correct, knowledge cannot be transmitted by teachers — it can only be drawn out through the right kind of questioning. • Eikasia (ay-KAH-see-ah): Image-thinking — the lowest stage of cognition on Plato’s Divided Line. This is the condition of the cave-dwellers: taking shadows for reality, images for originals. For Plato, most people, most of the time, live in eikasia. • Doxa (DOX-ah): Opinion or belief. The middle range of cognition, where most people who have escaped the cave still remain — aware of the sensible world but not yet in contact with the Forms. Doxa was precisely what the Sophists trained their students to produce and deploy. For Plato, this was the problem. • Eidos (AY-dos): Form, or the eternal, unchanging pattern that physical things imperfectly imitate. The plural is ‘eide.’ When Plato says the philosopher ascends toward the Good, he means toward the highest of these Forms — the Form of the Good, the sun of the intelligible world.
Major Themes• Plato’s systematic response to the Sophists, organized across four dimensions: collectivity, cumulativity , teachability and rhetoric (episode 7) as civic engine — and what each reversal means for the idea of progress • The Allegory of the Cave as a theory of cognitive ascent: the four stages from shadow-watching to encounter with the Form of the Good, and why the ascent is always individual, never collective • The Meno paradox (‘80a): how can you inquire into what you do not know? And what Plato’s answer — anamnesis — implies about the nature and limits of teaching • In the Meno: Socrates draws out geometrical knowledge from an uneducated slave boy through questioning alone — what this shows about knowledge, and what it forecloses about cumulative progress • The Divided Line (Republic 509d–511e) as the epistemological map behind the Cave: the relationship between image-thinking, belief, reasoning, and understanding. More on the divided line to come in episode 7. • The political cost of philosophical ascent: why the philosopher, having seen the light, is obligated to return to and to r

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.
