Notions of Progress

Marshall Madow

The idea of progress — that humanity advances through time toward something better — has been a contested assumption throughout history. The question of whether we as a species, a nation, or as individuals are progressing is being interrogated with a renewed urgency that the present moment demands. Whether that advancement is real, illusory, unevenly distributed, or simply beside the point depends on who is asking, from where, and by what measure. Notions of Progress is a podcast that takes those questions seriously, tracing how the idea of progress has been understood, contested, and reimagined from antiquity to the age of artificial intelligence. The series moves from the ancient Greeks’ ambivalence about technological change, through the Enlightenment’s confidence in cumulative human reason, to the contemporary moment in which artificial intelligence has made the question of progress newly urgent. When machines appear to learn, create, and reason, the assumptions buried inside the word “progress” — about agency, direction, and human advancement — are no longer abstract. Tracing how those assumptions formed, and how they have been challenged across centuries, is the work of this podcast. Rather than prescribing a position, it surfaces the debates — examining how thinkers from Hesiod to Hayek, from Plato to Peter Haff, have understood what it means for humanity to move forward, at what cost, for whom, and by whose definition. The thread connecting Plato’s Academy to the age of artificial intelligence is not a straight line of accumulation — it is a recurring argument about whether progress is something driven by human agency, providence, or an artificial consciousness we project onto history rather than find in it. Host Marshall Madow brings an unusual dual formation to these questions. His MA in History from Cambridge University — where his thesis examined Georges Sorel’s epistemology of myth and the role of ideas in animating collective action — gave him a grounding in how belief systems about progress can function in place of rational thinking as historical forces. His MSc from Oxford University’s Saïd Business School, specializing in Complexity Science and Leadership, introduced him to the question from the other direction: how systems evolve, how change propagates through institutions, and why linear models of advancement are often insufficient in explaining complex phenomena. The two areas of study point toward the same problem from opposite ends. Notions of Progress is the inquiry that connects them. Marshall approaches the podcast as a scholar, researcher, and curator — seeking to surface a pluralistic and wide-ranging spectrum of ideas rather than prescribing or advocating one position over another.

    Interview with Matt Ehret Pt. 2: The Allegory of the Cave

    What if the most cited passage in Western philosophy has been deliberately misread — by both its critics and its supposed followers? In Part 2 of his conversation with Matt Ehret, Marshall examines the Allegory of the Cave, the Sophist movement, and a lineage of misuse running from ancient Athens to Leo Strauss and the neoconservative movement. Ehret argues that the Republic is not the blueprint for authoritarian rule that critics have called it. Plato’s method — as Ehret reads it across episodes 11 and 12 — is always diagnostic: the dialogue poses negative examples to expose unexamined assumptions, not to prescribe conclusions. The Allegory of the Cave, Book VII of the Republic, demonstrates this method at its most concentrated. Two groups, Ehret contends, have each extracted the imagery they found useful and stopped reading before the passage that changes everything: the philosopher’s obligation to return to the cave, out of love for those still inside, even at personal risk. The episode traces this misreading from its ancient roots — through Neoplatonist appropriations of the cave imagery — to its modern recurrence in Leo Strauss, the University of Chicago, and the neoconservative foreign policy establishment. Peter Thiel’s 2007 essay “The Straussian Moment” and Augustine’s battle against Gnostic Neoplatonism round out the arc. This is Part 2 of a three-episode conversation with Ehret tracing the Plato–Aristotle divide and its consequences for Western intellectual history.

Behind them, puppet masters control what is projected; above, a fire burns; beyond the cave, the sun represents truth itself. Ehret argues — drawing on the Republic throughout this episode — that the allegory is a graduated account of how knowledge deepens: from shadow, to object, to the light of the sun. The passage is diagnostic rather than prescriptive. Plato is not recommending that puppet masters govern society; he is showing how unexamined assumptions trap minds at the level of shadow. The Noble Lie — a founding myth designed to bind a society The term appears in the Republic when Socrates proposes that a well-ordered city might require a founding myth — a story told to citizens about their origins that is not literally true but that binds them to the political community. Leo Strauss, in Ehret’s account, extracted this concept and used it as the philosophical authorization for a governing class that manages the beliefs of the population through deliberate narrative control. The question Ehret presses — and that the episode explores — is whether Plato intended the noble lie as a genuine recommendation or as another diagnostic trap for the naive reader, one more unexamined assumption that the careful student should question rather than adopt. Gnostic Neoplatonism — a mystical distortion of the Platonic tradition Neoplatonism, in its ancient form, drew selectively on Plato’s dialogues to construct a hierarchical cosmology in which the soul ascends through successive levels of being toward union with a transcendent One. Ehret argues that this tradition — associated with thinkers such as Plotinus and, later, with Gnostic sects — is a deliberate inversion of authentic Platonism. Where Plato’s philosopher is obligated to return to the cave, the Neoplatonist’s initiate seeks escape from the material world into pure transcendence. Ehret reads Augustine’s theological battles against the Gnostics as recognition of this same split: the authentic tradition holds that good, truth, and beauty are positive principles; the Gnostic tradition resolves all contradictions into a “great nothingness.” Straussianism — Leo Strauss’s doctrine of esoteric political philosophy Leo Strauss (1899–1973), philosopher at the University of Chicago, argued that the great political philosophers wrote on two levels: an exoteric teaching for the general public and an esoteric teaching reserved for the initiated few capable of reading between the lines. Ehret places Strauss in the Neoplatonist lineage: a thinker who extracted from Plato’s Republic the concept of the noble lie and built from it a theory of governance in which a trained elite manages political reality for a population that cannot handle the truth. Strauss’s students, in Ehret’s account, include Donald Rumsfeld, Richard Perle, and Paul Wolfowitz — architects of a foreign policy tradition that Ehret argues follows directly from this premise. Fascinating Historical InsightsThe Part of the Cave That Everyone Leaves OutThe Allegory of the Cave is among the most frequently cited passages in Western philosophy. Most readers know the imagery: prisoners, shadows, a fire, an ascent toward the sun. Fewer reach the moment that Ehret argues changes everything. In Book VII of the Republic, Plato has Socrates describe what happens after the philosopher escapes the cave and reaches the light. Most readers stop there — the story seems complete. But Plato continues: the true philosopher is not the one who escapes into the light and stays. The obligation is to return into the cave, even at personal risk, to assist those still chained inside. Socrates, in Ehret’s reading, is the embodiment of that obligation — and his death by popular vote in 399 BCE is the demonstration of the risk. The omission of this return is, for Ehret, the defining act of misreading that allows the cave imagery to be turned into a theory of elite management rather than philosophical obligation. Leo Strauss, the University of Chicago, and the Neoconservative LineageLeo Strauss taught political philosophy at the University of Chicago from the 1930s through the 1960s. Ehret argues that Strauss operated with two registers — a public teaching and a private one — and that his private teaching drew directly on the Platonic noble lie as a philosophical foundation for elite governance. The students Ehret identifies as carrying that teaching into political practice include Donald Rumsfeld, Richard Perle, and Paul Wolfowitz, each of whom held senior positions in the foreign policy apparatus of the United States in the early twenty-first century. Ehret’s argument is not that Strauss invented this tradition but that he was its modern vehicle — a transmission point in a lineage that, in Ehret’s reading, runs from misappropriated Platonism through early modern political philosophy and into contemporary governance. Peter Thiel’s ‘The Straussian Moment’In 2007, the technology investor and political thinker Peter Thiel published an essay titled “The Straussian Moment.” Ehret discusses the essay as evidence that the Straussian tradition is not confined to academic philosophy departments or Cold War-era foreign policy circles. Thiel situates himself within what Ehret describes as a secret-doctrine lineage — a tradition he traces not only through Strauss but back through Locke, Hobbes, and Bacon to an older practice of writing with two registers. The essay’s significance for this episode is not its specific political conclusions but its candor: a prominent public intellectual explicitly acknowledging and affiliating with a tradition of esoteric political philosophy that Ehret argues is rooted in the misreading of the Allegory of the Cave. Augustine’s Battle Against the GnosticsBefore his conversion to Christianity, Augustine of Hippo was himself a member of the Manichaean Gnostic movement — a sect that, in Ehret’s account, embodied the Neoplatonist inversion he traces throughout this episode. Augustine’s eventual rejection of the Manichaeans and his sustained theological engagement with Gnostic doctrines across his mature writings represent, for Ehret, a recognition of the same split he identifies between authentic Platonism and its distortion. Ehret points to the Gnostic Nag Hammadi scriptures as the textual repository of the false Platonic tradition, and to the writings of Paul and the Gospels as carrying, in his reading, the best of authentic Platonic philosophy. The Augustine passage gives the episode’s theological thread a specific historical anchor: the Plato–Aristotle divide, for Ehret, is not only a philosophical fault line — it runs through the history of Christianity as well.

  2. Interview with Matt Ehret - Plato vs. Aristotle: The Flame, the Vessel, and the Fate of Human Progress

    May 18

    Interview with Matt Ehret - Plato vs. Aristotle: The Flame, the Vessel, and the Fate of Human Progress

    Matt Ehret argues that the divide between Plato and Aristotle is not a historical curiosity confined to the ancient world — it is a living fault line that continues to shape how civilizations understand learning, discovery, and human advancement. In this first of three episodes with Ehret, he makes the case that the Platonic method — learning as recollection, knowledge as something awakened from within rather than deposited from outside — is the engine of genuine human progress. The Aristotelian method, which begins with closed axioms and fills the student as a vessel from without, produces in his reading increasingly sophisticated illusions of progress: the appearance of accumulation without the substance of discovery. Ehret grounds this argument in the founding conditions of Plato's Academy — its geometry requirement, its Pythagorean foundations through Archytas of Tarentum, and its core pedagogical premise that a student must construct knowledge rather than receive it. The Meno dialogue serves as the episode's central demonstration: Socrates leads an uneducated slave boy to geometric truth not by instruction but by guided questioning, showing that genuine understanding is always an act of recollection, not reception. The episode closes on its first Plato–Aristotle contrast: a verb-driven universe against a noun-driven one — and leaves open the question of which tradition the West has actually been running on. This is Part 1 of a three-episode arc with Ehret tracing the Plato–Aristotle divide and its consequences for Western intellectual history. Show Notes & Timestamps00:00 — Introduction to Progress and Ideas 00:29 — Welcome to Notions of Progress 02:24 — Introducing Matt Ehret 03:27 — Today’s Focus: Ideas as Operating Systems 07:51 — The Platonic Method: Learning as Discovery 12:45 — The Academy: Plato’s Educational Innovations 15:16 — The Meno Dialogue: Virtue and Knowledge 21:05 — Sophistry vs. Philosophy: The Battle for Wisdom 35:58 — The Allegory of the Cave Key Concepts & TermsConstructive GeometryThe method of geometric reasoning that Plato required of all Academy students — and that Ehret identifies as the epistemological foundation of the Platonic tradition. In constructive geometry, the student begins with no axioms and no assumptions. Instead of being told that a square has four equal sides and right angles, the student is asked to construct one from scratch using only a compass and straightedge, discovering its properties through the process of building it. Nothing is taken on faith; everything must be demonstrated. Ehret contrasts this with the Aristotelian approach, which begins with fixed definitions and proceeds deductively from them. For Plato, geometry taught in the constructive mode was not merely a mathematical exercise — it was training in the discipline of genuine discovery, preparing the mind to approach questions of justice, virtue, and political life without being captured by false reasoning. Anamnesis (an-am-NEE-sis)The Greek term for recollection, and the name Plato gives to his theory of how genuine knowledge is acquired. Plato argues — most explicitly in the Meno — that the soul already contains knowledge of the eternal truths of mathematics, geometry, and virtue. What we call learning is not the addition of new information to an empty container but the reawakening of what the soul already knows. Ehret uses this concept to draw the sharpest distinction between the Platonic and Aristotelian frameworks: where Aristotle imagines the student as a vessel to be filled, Plato imagines the student as a flame to be lit. The Meno's slave boy demonstration — in which Socrates guides an uneducated boy to geometric truth through questioning alone, without ever stating the answer — is the episode's central illustration of anamnesis in action. Tabula Rasa (TAB-yoo-la RAH-sa)Latin for 'blank slate.' The concept, closely associated with Aristotelian and later Lockean epistemology, that the human mind at birth contains no innate knowledge — it is an empty surface on which experience writes. Ehret invokes this term to clarify what the Platonic method explicitly rejects. For Plato, knowledge is not inscribed on the mind from outside; it is recollected from within. The pedagogical consequences are profound: a tabula rasa model produces a teacher who transfers information and a student who receives it. A Platonic model produces a teacher who poses questions and a student who makes discoveries. Ehret argues that the history of Western education has largely followed the tabula rasa model — with consequences for how institutions understand progress. Archytas of Tarentum (ar-KY-tas of ta-REN-tum)The Pythagorean mathematician and statesman (c. 428–347 BCE) whom Ehret identifies as a direct intellectual precursor to Plato's Academy. A close friend of Plato's, Archytas was the first to solve the problem of doubling the cube — finding a cube with exactly twice the volume of a given cube — not through algebraic calculation but through a purely geometrical construction involving a cone, a cylinder, and a sphere. Ehret presents this achievement as the paradigm case of constructive geometric reasoning: a problem that defeated purely mathematical approaches was solved by someone who understood geometry as the investigation of physical reality, not the manipulation of symbols. Archytas's students formed the first generation of Plato's Academy, and his influence is visible in the inscription above the Academy's entrance: Let no one who does not know geometry enter these walls. Fascinating Historical InsightsThe Inscription Above the Academy's EntranceWhen Plato founded his Academy in Athens around 387 BCE, he placed an inscription above the entrance that read: Let no one who does not know geometry enter these walls. Ehret describes this not as an administrative gatekeeping measure but as a philosophical statement about the kind of mind the Academy was designed to cultivate. Geometry, in the constructive mode Plato required, was the discipline that trained students to make genuine discoveries rather than accept received truths — to discover rather than assume. By the time a student had demonstrated genuine geometric competence, they had already practiced the essential intellectual virtue the Academy demanded: the willingness to suspend assumed knowledge and work toward truth through their own demonstrated reasoning. Doubling the Cube: A Problem That Required a New Kind of ThinkingOne of antiquity's three great unsolved geometric problems — alongside trisecting an angle and squaring the circle — was the Delian problem: how to construct a cube with exactly double the volume of a given cube. Purely mathematical approaches consistently failed. Archytas of Tarentum solved it around 400 BCE using a three-dimensional geometric construction involving a cone, a cylinder, and a torus — a solution that required imagining the intersection of three surfaces in space. Ehret presents this as the defining example of constructive geometry's power: the problem yielded not to more sophisticated calculation but to a fundamentally different mode of thinking. Plato's friendship with Archytas, and his incorporation of Archytas's students into the Academy's founding cohort, meant that this discovery-oriented, construction-first approach became the Academy's pedagogical foundation. The Slave Boy Demonstration in the MenoIn Plato's Meno dialogue, Socrates undertakes an unusual demonstration. He calls over an uneducated slave boy — a young man with no formal mathematical training — and, through a sequence of carefully posed questions, guides him to discover the geometric principle for doubling the area of a square. Socrates never states the answer. He poses questions, allows the boy to make wrong assumptions, lets him discover his own errors, and waits for the correct insight to emerge from the boy's own reasoning. At the end, the boy has arrived at a genuine geometric truth — not by being told it, but by finding it himself. Plato's point, as Ehret reads it, is not modest: this demonstration shows that genuine knowledge is always recollection. The capacity for mathematical truth was already latent in an uneducated slave. What Socrates provided was not information but the conditions in which discovery could occur. A Noun-Driven Universe vs. a Verb-Driven UniverseNear the close of the episode, Ehret introduces the first of the contrasts he will develop across the three-part arc: Plato and Aristotle understood reality itself in fundamentally different terms. For Aristotle, the universe is composed of substances — things with fixed natures, definable by their essential properties. The task of knowledge is to correctly categorize these substances and reason from their definitions. The universe, on this model, is fundamentally noun-shaped. For Plato, reality is dynamic: the eternal forms exert an ongoing influence on the changing world of appearances, and the soul is always in motion toward or away from truth. Knowledge is not the correct labeling of fixed things but an active, ongoing process of recollection and discovery. The universe, on this model, is fundamentally verb-shaped. Ehret argues this distinction carries consequences far beyond ancient philosophy — it shapes how Western civilization has understood learning, progress, and what it means to advance.

    Aristotle vs. Plato: Two Theories of Progress — and the Institution That Produced Both

    The Academy was built on a wager: that philosophy could be institutionalized, accumulated, and transmitted across generations. Episode 10 asks whether the bet paid off — and finds the answer in the man Plato trained himself. This episode traces Aristotle’s intellectual break with Plato, the philosophical distance between their two theories of human advancement, and the founding of the Lyceum as a counter-proposal, not a repudiation. Drawing on Prof. G.E.R. Lloyd’s account of Aristotle’s development, Prof. W.K.C. Guthrie’s biographical anchor in A History of Greek Philosophy (Vol. VI), Prof. Werner Jaeger’s reading of the Cave in Paideia, and Prof. Christopher Moore’s argument in Calling Philosophers Names that Aristotle carried the Academy’s founding principle out the door when he left, the episode reconstructs what the break actually was — and what it was not. The Academy trained its members in dialectical argument without demanding conformity. That method produced its most consequential critic. Moore identifies the principle Aristotle took with him: since progress in philosophy is possible, bring everything of relevance to bear on every question. The bet succeeded in producing a thinker capable of exactly what it promised. It failed in that the institution could not contain him. Both verdicts stand simultaneously. This is the third and concluding episode of the Academy Arc — from the naming of philosophy in Episode 8, through the institution’s mechanics in Episode 9, to the first full test of the founding bet here. Show Notes & Timestamps00:00 — Opening04:36 — Aristotle’s Break06:45 — Two Theories of Agency09:57 — The Vertical Cumulativity Test12:34 — The Lyceum and the Long Argument15:57 — Closing Key Concepts & TermsTechnē (TEK-nay) — craft, skilled making The word has run through this series since Episode 2, where it named the earliest Greek anxiety about technology as gift and curse. It returns here in a new register. Where Plato held that technē was insufficient knowledge without philosophical governance above it, Aristotle argued it constituted a legitimate form of understanding in its own right. As Prof. Lloyd reads him, the builder who knows the purpose of the house does not need a philosopher to supply that knowledge from outside. Technē, in Aristotle’s hands, becomes evidence that genuine knowledge does not require the vertical ascent Plato’s curriculum demanded. Telos (TEH-los) — end, purpose, goal For Plato, the telos of human life points toward the Forms: eternal, unchanging, and above the world of change. As Prof. Lloyd describes Aristotle’s departure, the telos is relocated — it is immanent, already inside things, waiting to be actualized from within. The seed does not reach toward an eternal original. It already is, potentially, what it will become. Whether this relocation of telos liberates human potential or quietly constrains it — by fixing in advance what each kind of thing can become — is a question the scholarship has not resolved. The Forms (the Platonic Forms) — eternal, unchanging originals Plato’s claim that behind every particular beautiful thing, just act, or excellent person, there stands an eternal, unchanging original that the particular imperfectly resembles. Aristotle disputed this directly. As Prof. Lloyd argues, form in Aristotle’s model is something gradually acquired during the process of change — not contemplated from above. The philosophical distance between the two men on this point is not a disagreement at the edges. It concerns the nature of reality, the structure of knowledge, and the question of who is capable of progress. Praxis (PRAK-sis) — purposeful human action Aristotle’s account of practical knowledge — reasoning oriented toward action in the world — stands behind one of the most consequential inheritances of his thought. As scholars including Richard Bernstein have argued, Karl Marx’s concept of praxis draws directly on Aristotle’s account, treating purposeful human action as the engine of historical change. The lineage runs from Aristotle’s Nicomachean Ethics through centuries of political philosophy to modern social theory. Fascinating Historical InsightsThe Break That Began Inside the Academy The familiar image of Aristotle is of a hardheaded empiricist who arrived at Plato’s school and promptly dismantled it. Prof. Lloyd disputed this image: Aristotle’s earliest works — the Eudemus and the Protrepticus — argue that the soul in its true and natural state is separate from the body, and that the highest human activity is philosophical contemplation, withdrawn from the world. These are not the positions of a critic. They are the positions of an adherent. Prof. Lloyd’s account makes the historical point plain: the break was gradual, and it began from the inside. Aristotle was already criticizing the theory of Forms while still identifying as a Platonist. The institution’s own method — dialectical argument without demanded conformity — made that possible. A Departure That Was Also a Political Exit When Plato died in 347 BCE and Speusippus was chosen to lead the Academy, Aristotle left Athens. The departure is often told as a philosophical rupture. Prof. Guthrie’s account is more careful: Aristotle left with Xenocrates, a conservative Platonist, heading toward another Platonic circle in Asia Minor. He was also a metic — a resident alien without citizen rights — with Macedonian ties in a city inflamed against Macedon. The departure was politically overdetermined as well as philosophically motivated. It was not a rejection of the Academy. It was an exit the Academy had, in a real sense, made inevitable. Two Verdicts, Simultaneously True Prof. Moore identifies the principle Aristotle carried out when he left: since progress in philosophy is possible, bring everything of relevance to bear on every question. Aristotle had absorbed this from the Academy itself. He then applied it fully — and it eventually led him away from Plato’s Forms, away from the curriculum, and into a school of his own. The founding bet therefore produced two verdicts at once. It succeeded in producing a thinker capable of exactly what it promised. It failed in that the institution could not contain him. Moore’s formulation holds both outcomes without resolving the tension between them. That refusal to resolve is itself the argument. From the Lyceum to the Modern Research University When Aristotle returned to Athens in 335 BCE, he established himself at the Lyceum — an existing public gymnasium — and built around it a community of inquiry with a shared library, common meals, and rules of procedure. As Prof. Guthrie notes, the customs were modelled on the Academy: a counter-proposal, not a repudiation. As Prof. Lloyd describes it, what the Lyceum institutionalized was systematic research across every field, carried on and extended by Aristotle’s successors after his death. The organizing principle — accumulate knowledge through practice and open inquiry, not formation toward a philosophical summit — surfaced later within medieval universities and the modern research institution. The Lyceum did not merely produce knowledge. It modelled a form of intellectual life that outlasted every institution built on Platonic principles.

    How Did Plato’s Academy Teach What Could Not Be Taught?

    Plato named philosophy. But naming it was only the first move. The harder question was whether an institution could be built to make the progress he was wagering on actually work. Episode 9 examines the Academy — not as an idea, but as a place, a community, and a method. Drawing on Prof. W.K.C. Guthrie’s account in A History of Greek Philosophy (Vols. IV and VI), Prof. Werner Jaeger’s Paideia: The Ideals of Greek Culture (Vol. II), and Prof. Christopher Moore’s Calling Philosophers Names, this episode traces what the Academy was in physical and intellectual terms, how it taught through Plato’s radical redefinition of paideia as conversion rather than transmission, and what the Academy’s curriculum reveals about the kind of knowledge Plato believed could anchor cumulative philosophical progress. It then turns to the succession problem — who leads the institution when the founder dies — and closes on Aristotle’s twenty years inside the Academy as the founding bet working exactly as designed: producing a genuine thinker capable of departing. This is the second of three episodes tracing the founding of the Academy, from the naming of philosophy in Episode 8, through the institution’s mechanics here in Episode 9, to Aristotle’s departure and the first full test of the founding bet in Episode 10.

As Prof. Jaeger reads the Republic, Plato takes the word back from the Sophists entirely: true paideia is not skill-transmission but the conversion of the whole soul — a turning around (periagoge) from shadow toward light. Propaideia (pro-pay-DAY-ah) — Preparatory training. The name for the mathematical programme that precedes philosophical dialectic in the Academy’s curriculum: arithmetic, geometry, stereometry, astronomy, and harmonic theory. Mathematics is not the goal; it is the necessary discipline the mind must undergo before genuine philosophical inquiry becomes possible. Episteme (ep-IS-teh-may) — Genuine knowledge: understanding that can give a full account of itself and withstand the most sustained questioning without collapsing. Distinct from doxa (opinion), even correct opinion, which cannot guarantee its own stability across time and argument. The Academy’s founding wager is that episteme — unlike rhetoric — can be reliably preserved and extended across generations. Dialectic (dy-ah-LEK-tik) — The method of sustained philosophical questioning and counter-questioning aimed at genuine knowledge. Not rhetorical debate, not the scoring of points, but the rigorous, progressive examination of a claim until it either stands or collapses under its own weight. Socrates practiced it in the streets of Athens; the Academy institutionalized it as a discipline that, on Plato’s own account, took fifteen years to master. Fascinating Historical InsightsThe Lecture Nobody Understood Plato once gave a public lecture on the Good — and most of the audience left baffled. As Prof. Guthrie records it, Plato attempted to present the philosophical core of his thought in a single address, and the audience arrived expecting wisdom but encountered mathematics. Most departed confused. Aristotle, Guthrie notes, was reportedly one of the very few who stayed and followed. The episode is not merely anecdotal. It is evidence that the Academy’s inner circle was deliberately operating at a level of abstraction inaccessible to the wider public — not out of elitism for its own sake, but because, on Plato’s vertical model of progress, genuine philosophical understanding cannot be popularized without being falsified. Two Schools, Two Theories of Progress The Academy had a direct rival in fourth-century Athens: the school of Isocrates. Where Plato trained philosophers, Isocrates trained orators and statesmen. As Prof. Guthrie makes clear, these were not merely competing pedagogies but competing theories of what genuine improvement for a city actually consists of. Isocrates argued for civic breadth — education spread wide, producing men capable of effective participation in democratic life. Plato argued for philosophical depth — slow, selective, cumulative formation over decades. The debate between these two schools is the ancient world’s first sustained institutional argument about whether progress is horizontal or vertical. A Community That Lived Its Philosophy The Academy was not a school in the modern sense. As Prof. Guthrie describes it, what Plato founded was a community of inquiry — a circle of philosophers who lived, studied, argued, and ate together over decades in the grove sacred to the hero Academus, about a mile northwest of Athens. There were shared meals (syssitia), shared walks, shared rituals, and a common subscription to expenses. Members were not fee-paying students; they were participants in a shared intellectual life. The structure was closer in spirit to a Pythagorean brotherhood or a religious community than to anything recognizable as a university. The Succession Problem and Its Philosophical Meaning When Plato died in 347 BCE, the question of who would lead the Academy was not merely administrative — it was philosophical. Prof. Guthrie’s account is careful: Speusippus, Plato’s nephew, was chosen. What is clear is the philosophical distance between the two men. And Aristotle, the other obvious candidate, was legally disqualified as a metic — a resident alien who could not inherit property in Athens without special dispensation. The choice of Speusippus revealed something structural: the institution designed to transmit philosophy across generations had no reliable mechanism to ensure that succession followed its best thinking. That is not a failure of planning. It is a consequence of the theory of knowledge the Academy was built on.

    The Word and the Wager: How Plato Named and Claimed Philosophy | Ep. 8 pt 1

    About This Episode Where did the word “philosopher” come from — and who got to decide what it meant? In Episode 8, Part 1 of Notions of Progress, we trace the moment Plato took a word that had begun as a mocking label and transformed it into an institutional claim. Prof. Christopher Moore’s Calling Philosophers Names (Princeton University Press, 2020) shows us how the coining of philosophos was not a neutral act of description but a polemical move — one that drew a sharp line between those who merely acquired knowledge and those who pursued wisdom as a lifelong orientation. Drawing on three of Plato’s dialogues — the Meno, the Phaedrus, and the Gorgias — the episode asks what it meant to found a school on that claim and what that founding bet risked. Prof. W.K.C. Guthrie’s historical account of the early Academy situates the institutional stakes. The episode traces the distinction between episteme — genuine knowledge — and doxa — mere opinion — as the intellectual fault line on which Plato’s entire wager rests. This is the first of three episodes tracing the founding of the Academy, from the naming of philosophy through the institution’s mechanics to Aristotle’s departure and the first test of the founding bet. —————————————————————— Show Notes & Timestamps 00:00 — Introduction to Plato’s Philosophical Journey02:18 — The Birth of the Academy and Its Claims04:17 — The Evolution of the Term ‘Philosophos’07:57 — The Distinction Between Episteme and Doxa11:51 — Plato’s Selective Approach to Knowledge12:52 — Aristotle’s Departure and Philosophical Expansion13:33 — Recap —————————————————————— Key Concepts & Terms Philosophos (phil-OH-soh-foss) — lover of wisdom As Moore demonstrates across pre-Platonic and Platonic sources, the word did not emerge as a neutral description. It circulated as a mildly mocking label before Plato claimed it, narrowed it, and redefined its referent entirely. In Moore’s reading, Plato’s decision about who counts as a philosophos is simultaneously a decision about what kind of knowledge matters and who is capable of it. The naming of the discipline was the first move in the founding of the Academy. Episteme (ep-ISS-teh-may) — genuine knowledge Stable, reasoned knowledge — as distinct from opinion — and the object the Academy was founded to produce and transmit. The Meno’s conclusion — that the virtuous statesman operates by true opinion, not knowledge — is the challenge the Academy was built to answer. If doxa cannot be systematically taught or institutionally transmitted, only episteme justifies the existence of a philosophical school. Guthrie’s commentary situates this distinction as Plato’s foundational move against both the Sophists and the democratic assumption of broadly equal political capacity. Doxa (DOX-ah) — opinion or true belief Distinguished from episteme in the Meno. The virtuous statesman operates by true opinion, not knowledge — like a poet who produces fine things without being able to say why. The Sophist educational programme produces doxa, not episteme — and doxa cannot be systematically taught or institutionally transmitted. Plato’s point is that true opinion, however reliable in practice, will not hold under examination. Technē (tek-NAY) — craft or genuine expertise The central spine of the series from Episodes 5–8. A genuine technē has a determinate subject matter, aims at the genuine good of its object, and can give a rational account of itself. The Sophists claimed rhetoric was a technē ; Plato argued in the Gorgias that it was not — it is a knack (empeiria), producing persuasion without understanding why. The Academy’s founding claim was that philosophy met the genuine standards of technē and exceeded them, because its object was not persuasion but truth. —————————————————————— Fascinating Historical Insights A Philosopher Was Originally a Term of Mockery Before Plato, the word philosophos was not a badge of honour. As Moore traces across pre-Platonic sources, the term circulated as a mildly pejorative description — someone suspiciously over-interested in ideas, impractical, unworldly. Plato’s intervention was to take this floating, slightly comic label and claim it entirely: stripping away its mocking connotations, redefining the word’s referent, and making it describe something altogether more serious. The episode shows how this terminological move was simultaneously a philosophical argument and a political act. The Academy’s Founding Claim Was Unprecedented in the Ancient World What Plato built was not a school in the conventional Sophist sense — a travelling teacher offering instruction for fees. It was a fixed, sustained community of inquiry organised around a shared method and the explicit claim that genuine knowledge, as distinct from opinion, was achievable and transmissible across generations. As Guthrie’s account of the early Academy makes clear, no institution in the ancient world had previously staked its existence on quite this claim. The Academy’s founding was an assertion that philosophy could accumulate: that the next generation could begin where the last left off. Aristotle Was at the Academy for Twenty Years — and Then Left Aristotle arrived at the Academy as a young man and remained for twenty years, until Plato’s death. His departure — and his subsequent founding of the Lyceum — is one of the most consequential intellectual events in ancient history. The episode treats this not as a biographical footnote but as the first serious test of the Academy’s founding bet. If philosophical knowledge genuinely accumulates across generations, Aristotle’s twenty years should have produced a philosophical heir. That he left instead and built something different is the question Episode 10 will address directly. Episteme and Doxa: A Philosophical Argument Against Democracy Plato’s insistence that episteme is categorically different from doxa was not merely an epistemological position. It was a claim about who is capable of governing. The Sophists had argued that political skill was a form of expertise acquirable by any citizen willing to learn rhetoric. Plato’s distinction cuts against this entirely: if most people operate at the level of opinion and only the philosophically trained can attain genuine knowledge, the democratic premise — that citizens are broadly equal in their capacity for political judgment — is philosophically undermined. The founding of the Academy was, among other things, a counter-argument to Athenian democracy. —————————————————————— Resources & Further Reading Primary Sources Plato. Meno, 87c–100b.

    Plato vs. the Sophists: Rhetoric, Power, and the Making of Callicles | Ep. 7 pt 2

    About This Episode Can rhetoric make better citizens — or does it simply make better manipulators through the art of persuasion? In Part 2 of the Plato vs. the Sophists arc, Notions of Progress follows Plato’s argument from the Meno to the Gorgias to answer that question. Building on Part 1’s examination of the Cave allegory and the doctrine of recollection, this episode turns to Plato’s two remaining pillars of response to the Sophists: the unteachability of virtue and the failure of rhetoric as a genuine craft. Scholars W.K.C. Guthrie, E.R. Dodds, Roslyn Weiss, George Klosko, and G.B. Kerferd serve as the scholarly guides. The Meno dismantles the Sophist educational claim — virtue cannot be taught by the Sophist mechanism. The Gorgias then dismantles the Sophist political claim — rhetoric is not the engine of civic progress but its counterfeit. The episode culminates with Callicles: not a villain, but the coherent product of Sophist education working exactly as intended. Applying Retz’s framework, Plato’s counter-attack forecloses the Sophist horizontal theory of civic progress entirely — and replaces it with a vertical reorientation toward the Forms. ―――――――――――――――――――― Show Notes & Timestamps •     00:00 Introduction to Plato’s critique of Sophist education •     05:54 Can virtue be taught?

For the Sophists, paideia centred on the transmission of rhetorical skill as the master tool of civic virtue. Plato’s argument in the Gorgias is that this programme mistakes a knack for a craft — and that its endpoint, as Klosko demonstrates through Callicles, is the production of men who equate political success with moral worth. Technē [please add pronumciation] — craft or genuine expertise A genuine technē meets three criteria in Plato’s examination: it has a determinate subject matter, it aims at the genuine good of its object, and it can give a rational account of itself. Dodds frames the opening of the Gorgias as a direct test of whether rhetoric qualifies. On every count Socrates argues it fails — rhetoric has no fixed domain, aims at what pleases rather than what is good, and cannot explain its own principles. It is a knack (empeiria), not a craft. Aporia [please add pronumciation] — productive impasse The state of genuine puzzlement that Socratic inquiry produces. The Meno ends in aporia: virtue cannot be taught by the Sophist mechanism, but what genuine virtue-teaching would require is left deliberately open. As Weiss reads it, this is not a failure of the argument but its point — the clearing of false certainty is the precondition for genuine philosophical inquiry. Doxa [please add pronumciation] — true opinion Distinguished from episteme (genuine knowledge) in the Meno. The virtuous statesman operates by true opinion, not knowledge — like a poet who produces fine things without being able to say why. Plato’s point is that true opinion, however reliable in practice, will not hold under examination. The Sophist educational programme produces doxa, not episteme — and doxa cannot be systematically taught or institutionally transmitted. ―――――――――――――――――――― Fascinating Historical Insights Dodds and the Nietzsche Connection In his appendix to Plato: Gorgias, Dodds draws a direct line between Callicles and Nietzsche’s will-to-power tradition. The resemblance, Dodds argues, is not accidental — both thinkers start from the premise that conventional justice is simply the mechanism by which the weak restrain the strong. Callicles anticipates the Nietzschean critique of slave morality by two and a half millennia. Dodds takes the connection seriously enough to devote a full appendix to it, treating Callicles not as a period piece but as a recurring philosophical position that resurfaces whenever civic consensus breaks down. The Deliberate Aporia of the Meno The Meno does not end with a refutation. It ends with a question deliberately left open. As Weiss reads it, Plato’s conclusion — that virtue comes by divine dispensation rather than teaching — is not his final word on the subject but a provocation. The Sophists claimed to be precisely the teachers the Meno cannot find. By ending in aporia rather than resolution, Plato signals that the problem of moral education is genuinely unsolved — and that the Republic will have to address it on entirely different foundations. Gorgias: Honourable but Unreflective Dodds’s reading of Gorgias himself is one of the episode’s more nuanced moments. Gorgias is not dishonest — he simply has not thought through the implications of his own craft. When Socrates forces the question of whether rhetoric can be used for injustice, Gorgias retreats: he assumes his students already know what is just. Dodds reads this not as evasion but as genuine unreflectiveness. The crack in the Sophist edifice, Plato shows, runs through its most honourable representative — not just through its most dangerous one. The Escalation from Gorgias to Polus to Callicles Klosko’s reading of the three interlocutors as a dramatic sequence is one of the episode’s structural anchors. Gorgias assumes virtue; Polus drops the pretence and argues for power openly; Callicles takes the logic to its conclusion and argues that natural superiority justifies domination. The escalation is Plato’s argument in dramatic form: the Gorgias does not need to state its conclusion — it enacts it across three progressively candid voices. ―――――――――――――――――――― Resources & Further Reading Primary Sources •     Plato.

    Plato vs. the Sophists: The Allegory of the Cave As His Answer On Progress | Ep. 6 pt 1

    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 rule over the dwellers of the cave — and what this means for Plato’s vision of the just city Fascinating Historical InsightsThe Death of Socrates and the Birth of Plato’s PhilosophyIn 399 BCE, a jury of 501 Athenian citizens voted to execute Socrates on charges of impiety and corrupting the youth. Plato was in his late twenties and is believed to have been present. Almost every major dialogue he wrote afterward can be read, in part, as a response to that verdict. The jury that condemned Socrates was drawn from the citizen body that the Sophists had spent decades educating in the arts of democratic persuasion. Plato’s attack on Sophistic rhetoric — and on the claims of democracy itself — cannot be separated from this biographical wound. The Meno Paradox and the Problem of InquiryAt Meno 80a, the character Meno poses what is sometimes called the paradox of inquiry: “How will you look for something when you don’t know at all what it is? … And even if you do happen upon it, how will you know that this is the thing you didn’t know?” This is not a sophistic trick. It is a genuine epistemological puzzle: inquiry seems to require already knowing what you’re looking for. Plato’s answer — that the soul already contains what it seeks, having encountered the Forms before birth — is one of the most ambitious moves in the history of philosophy, and it has direct implications for how he understands progress, pedagogy, and the limits of human teaching. The Slave Boy Who Already KnewTo demonstrate anamnesis, Socrates calls over Meno’s household slave — a boy with no mathematical training — and asks him a series of questions about the geometry of squares. Without being told anything, guided only by Socrates’s questions, the boy arrives at the correct answer. Socrates’s conclusion is that the knowledge was already there, latent in the soul, waiting to be drawn out. For Plato, this is not a pedagogical technique. It is a metaphysical demonstration: knowledge is not transmitted from teacher to student — it is recovered by the soul from itself. The Philosopher Who Must ReturnThe Cave allegory does not end with the philosopher’s liberation. Having made the ascent from shadow to light, the philosopher is compelled to return — back into the cave, back among those who see only shadows, to serve as a ruler of the city. The philosopher does not want to return,but the just city, as Plato conceives it, requires that those who have seen the Good govern those who have not. Progress, in this view, is always asymmetric: a few ascend; the many remain below; and the one who has seen the light must sacrifice the vision to serve the darkness.

Prisoners chained in a cave see only shadows cast on a wall by objects behind them; they take the shadows for reality. One prisoner is freed, turns to face the light, and eventually ascends out of the cave into the sunlight — where he finally sees the objects themselves, and at last the sun, which Plato identifies with the Form of the Good. Julia Annas emphasizes that the Cave is not merely a metaphor about ignorance and enlightenment: it is a systematic account of the different cognitive levels mapped in the Divided Line, dramatized. For our purposes, the crucial feature is that the ascent is individual: one person makes the climb. There is no collective advance, no institutional accumulation, no transfer of the vision to others. The prisoner who ascends cannot bring the cave-dwellers with him. The Doctrine of Recollection: Anamnesis (Meno 80a–86c)Plato’s epistemological theory that the soul is immortal and has encountered the Forms before its birth into a body; what we call ‘learning’ is, strictly speaking, the recovery of this prior knowledge under the prompting of experience and questioning. W.K.C. Guthrie notes that anamnesis is Plato’s answer to the Meno paradox — it resolves the puzzle of how genuine inquiry is possible without already knowing the object of inquiry. But its implications for progress are radical. If knowledge is recovered rather than accumulated, there is no genuine cognitive progress in the historical sense. Each soul must make the recovery for itself. The Sophists’ claim that wisdom can be transmitted and that civilization advances through the accumulation of teachable skills is, on this view, doubly mistaken: it confuses opinion for knowledge, and transmission for genuine education. The Divided Line (Republic 509d–511e)Plato’s epistemological schema, introduced just before the Cave, in which he divides the objects of cognition into two main categories — the visible and the intelligible — and subdivides each. The four resulting levels, ascending from lowest to highest, are: eikasia (image-thinking), pistis (belief about visible things), dianoia (hypothetical mathematical reasoning), and noesis (understanding of the Forms themselves). The Cave allegory dramatizes the journey from eikasia toward noesis. Crucially, doxa — opinion, the highest cognitive state the Sophists cultivated and the democratic city depended upon — falls in the lower half of the line, in the realm of the visible ...

    The Sophists: Fifth Century Enlightenment? | Ep. 5 Pt.1

    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 recordGeorge 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 taughtJoshua Billings on the fifth-century enlightenment: three characteristic modes of Sophistic thought — empirical research, arguing both sides, and critical reasoning about divine causalityThe four major figures: Protagoras, Gorgias, Prodicus, and Hippias — what distinguished each of them and what they sharedProtagoras’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 themselvesWhether 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. Plato may have built his philosophy in the shadow of Socrates’ death — and the Sophists were part of what he was reacting against In 399 BCE, a jury of 501 Athenian citizens voted to execute Socrates. Plato was in his late twenties and witnessed it. In The Open Society and Its Enemies (1945), Karl Popper argued that what followed was an act of intellectual betrayal: Plato, he wrote, was Socrates’ “most gifted disciple” who “was soon to prove the least faithful.” The jury that condemned Socrates was composed of precisely the kind of citizens the Sophists had spent decades empowering — ordinary Athenians. Whether this was a conscious act of revenge or something Plato could not fully acknowledge, Popper carefully stated “I cannot doubt the fact of Plato’s betrayal... But it is another question whether this attempt was conscious.” (The Open Society and Its Enemies, Vol. 1, Ch. 10, p. 194–195) Plato /Socrates/Aristophanes In Plato’s Apology, Socrates himself argues that Aristophanes’ portrayal — performed 24 years before the trial. Addressing the jury, he seeks to disparage the playwright's work stating “You have seen this yourselves in the comedy of Aristophanes — a Socrates swinging about there, saying he was walking on air, and talking a lot of other nonsense about things of which I know nothing at all."¹ Plato, Apology 19c, in Plato: Complete Works, ed. John M. Cooper, trans. G.M.A. Grube (Indianapolis: Hackett, 1997).

Key Concepts/Terms Discussed The Fifth-Century Enlightenment: Joshua Billings’ term for the intellectual culture of 5th-century Athens, characterized by empirical research and systematic collection of knowledge (historia/polymathy), the practice of arguing both sides of questions (antilogy), and critical reasoning about traditional beliefs including divine causality. Billings sets forth a compelling case as to why the Sophists were not peripheral figures but “the characteristic thinkers of the fifth-century enlightenment.” (Billings, 2021) Technê as Constitutive, Not Instrumental: Rachel Barney’s distinction between ancient technê and modern concepts of technique or technology. Ancient technê is constitutive: it shapes the practitioner’s character, identity, and judgment through the practice itself. Modern technology tends to be understood as value-neutral tools serving pre-existing goals. For the Sophists, all human progress — from fire to justice — moved through technê in this deeper sense. The Constructed Reputation: Because almost all surviving accounts of the Sophists are hostile — especially Plato and Aristophanes — historians must reconstruct what they actually taught against the grain of the dominant tradition. Guthrie argues this requires distinguishing between the Sophists’ genuine philosophical contributions and the caricatures constructed by their opponents first and foremost Plato. Protagoras’s Myth of Human Origins: In the Protagoras dialogue, Plato has Protagoras recount a three-stage account of human development: no natural advantages → practical skill through technê (fire and the productive arts, given by Prometheus) → political skill through justice and mutual respect (distributed equally to all by Zeus). This myth is treated by scholars including Guthrie as encoding Protagoras’s genuine philosophical views about civilizational progress and democratic capacity. The Nomos–Physis Antithesis: The central intellectual controversy of fifth-century Athens: what is the relationship between human convention (nomos) and natural reality (physis)? The Sophists engaged seriously with this question from multiple directions — it is not reducible to a single position. Guthrie’s chapter on the nomos-physis antithesis traces the spectrum of views, from cosmopolitanism and humanitarian anti-slavery arguments to the more dangerous conclusions drawn by figures like Callicles.

About

The idea of progress — that humanity advances through time toward something better — has been a contested assumption throughout history. The question of whether we as a species, a nation, or as individuals are progressing is being interrogated with a renewed urgency that the present moment demands. Whether that advancement is real, illusory, unevenly distributed, or simply beside the point depends on who is asking, from where, and by what measure. Notions of Progress is a podcast that takes those questions seriously, tracing how the idea of progress has been understood, contested, and reimagined from antiquity to the age of artificial intelligence. The series moves from the ancient Greeks’ ambivalence about technological change, through the Enlightenment’s confidence in cumulative human reason, to the contemporary moment in which artificial intelligence has made the question of progress newly urgent. When machines appear to learn, create, and reason, the assumptions buried inside the word “progress” — about agency, direction, and human advancement — are no longer abstract. Tracing how those assumptions formed, and how they have been challenged across centuries, is the work of this podcast. Rather than prescribing a position, it surfaces the debates — examining how thinkers from Hesiod to Hayek, from Plato to Peter Haff, have understood what it means for humanity to move forward, at what cost, for whom, and by whose definition. The thread connecting Plato’s Academy to the age of artificial intelligence is not a straight line of accumulation — it is a recurring argument about whether progress is something driven by human agency, providence, or an artificial consciousness we project onto history rather than find in it. Host Marshall Madow brings an unusual dual formation to these questions. His MA in History from Cambridge University — where his thesis examined Georges Sorel’s epistemology of myth and the role of ideas in animating collective action — gave him a grounding in how belief systems about progress can function in place of rational thinking as historical forces. His MSc from Oxford University’s Saïd Business School, specializing in Complexity Science and Leadership, introduced him to the question from the other direction: how systems evolve, how change propagates through institutions, and why linear models of advancement are often insufficient in explaining complex phenomena. The two areas of study point toward the same problem from opposite ends. Notions of Progress is the inquiry that connects them. Marshall approaches the podcast as a scholar, researcher, and curator — seeking to surface a pluralistic and wide-ranging spectrum of ideas rather than prescribing or advocating one position over another.
