Beskrivelse

When Plato died in 347 BCE, he didn't leave the Academy to Aristotle. He left it to his nephew Speusippus—a man history has largely forgotten. In this episode, Lucas and Luna explore the life and philosophy of Speusippus of Athens, Plato's chosen successor who ran the Academy for eight years. They discuss his radical break from Plato's Theory of Forms, his focus on mathematics as the basis of reality, and his controversial claim that the Good is not a first principle. The episode also covers Speusippus's writings—now mostly lost—on pleasure, virtue, and the natural world, including his quarrel with Eudoxus of Cnidus. Why did Speusippus reject Plato's Forms? How did his philosophy influence later Neoplatonists? And why did Aristotle, not Speusippus, become the more famous student? This episode dives into the lesser-known succession crisis at the heart of ancient philosophy. #Speusippus #Plato #Academy #AncientGreece #Philosophy #TheoryOfForms #Neoplatonism #Eudoxus #Aristotle #Athens #Mathematics #Pleasure #Virtue #HellenisticPhilosophy #History #FexingoHistory #Podcast #Mediterranean Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]

episode Aristotle's Student in the Field: Theophrastus and the Birth of Botany cover

Aristotle's Student in the Field: Theophrastus and the Birth of Botany

Long overshadowed by his mentor Aristotle, Theophrastus was the ancient world's first systematic botanist. After Aristotle fled Athens in 323 BC, Theophrastus took over the Lyceum and began classifying plants with a rigor that wouldn't be matched for nearly two thousand years. This episode follows Theophrastus from his origins on the island of Lesbos to his landmark work *Historia Plantarum*, where he identified plant parts, described germination, and even speculated on photosynthesis. We also explore his other contributions—from his treatise on weather signs (*De Signis Tempestatum*) to his ethical *Characters*, a gallery of Athenian personality types. Theophrastus's legacy survived through the Byzantine scholar Arethas of Caesarea and later inspired Renaissance botanists like Leonhart Fuchs. Lucas and Luna delve into how one man's tireless observation and classification created a science that still underpins biology today. #Theophrastus #Aristotle #Lyceum #HistoriaPlantarum #AncientBotany #Lesbos #DeSignisTempestatum #Characters #Peripatetic #ArethasOfCaesarea #LeonhartFuchs #RenaissanceBotany #AncientGreece #HistoryOfScience #PlantClassification #Botany #FexingoHistory #Mediterranean Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]

Aristotle's Lyceum: The Peripatetic School That Shaped Science

In this episode, Lucas and Luna explore Aristotle's Lyceum, the philosophical school he founded in Athens in 335 BCE. Unlike Plato's Academy, the Lyceum was a research institution where Aristotle and his students collected specimens, dissected animals, and catalogued knowledge. Lucas explains how the Lyceum's 'Peripatetic' name came from Aristotle's habit of teaching while walking, and how the school pioneered systematic biology, zoology, and political science. They touch on Aristotle's collaboration with Theophrastus, his successor, and the massive collection of constitutions that informed the 'Politics'. The episode also covers the Lyceum's decline after Aristotle's flight from Athens, its revival under Andronicus of Rhodes, and its eventual disappearance. A fresh angle from previous episodes, focusing on the Lyceum as a proto-research university and its lost works on the constitutions of 158 Greek city-states. #Aristotle #Lyceum #Peripatetic #Theophrastus #AncientGreece #Philosophy #Science #Biology #Zoology #Politics #ConstitutionOfAthens #Athens #335BCE #AndronicusOfRhodes #AlexanderTheGreat #Hellenistic #History #FexingoHistory Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]

Aristotle's Biology: How a Philosopher Revolutionised Natural Science

When we think of Aristotle, we usually imagine the philosopher who founded logic and ethics. But he also spent years dissecting sea creatures off the island of Lesbos, cataloguing hundreds of species, and developing a theory of life that would dominate science for nearly two thousand years. In this episode of Fexingo History, Lucas and Luna explore Aristotle's biological works, including his observations of the cuttlefish, the chick embryo, and the strange reproductive habits of the eel. They discuss how Aristotle's concept of the soul as the 'form' of the body shaped his biology, and why his work on marine animals was so accurate that it was only surpassed in the 19th century. Along the way, they consider the legacy of his student Theophrastus, the role of dissection in ancient science, and the controversial theory of spontaneous generation. This is a side of Aristotle that rarely makes the textbooks, but it reveals a restless mind determined to understand every living thing. #Aristotle #Biology #HistoryOfScience #AncientGreece #Lesbos #Theophrastus #Cuttlefish #SpontaneousGeneration #Lyceum #PeripateticSchool #MarineBiology #Zoology #Embryology #NaturalHistory #Teleology #ScalaNaturae #History #FexingoHistory Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]

The Death of Socrates: Hemlock, Politics, and Philosophy's First Martyr

In 399 BCE, Athens condemned its most famous citizen to death. But what really happened in Socrates's final hours? This episode reconstructs the last day of Socrates's life using Plato's Phaedo, Xenophon's Apology, and legal records from the Athenian dikastēria. Lucas and Luna explore the political context behind the verdict—the lingering trauma of the Thirty Tyrants, the amnesty of 403 BCE, and the charges of impiety and corruption of youth. They examine the hemlock's effects on the human body, the ritual of the pharmakon, and the philosopher's calm refusal to escape despite Crito's bribe offer. They discuss the role of Xanthippe, the grief of his followers, and the final argument for the immortality of the soul. Sources include Plato's Phaedo and Crito, Xenophon's Memorabilia, Diogenes Laërtius, and modern toxicological studies. This is not just a story about one man's death—it's about how a civilization chooses to end a life when ideas feel threatening. And it raises a question that haunts liberal democracies still: how do you kill an idea by killing the person who holds it? #Socrates #Hemlock #Phaedo #Crito #Xanthippe #Athens #399BCE #Pharmakon #ImmortalityOfTheSoul #ThirtyTyrants #Amnesty #DiogenesLaërtius #Plato #Xenophon #Philosophy #Martyrs #History #FexingoHistory Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]

Socrates the Questioner: The Elenchus Method in Action

In this episode, Lucas and Luna dive into the heart of Socrates' philosophical method: the elenchus, or cross-examination. They explore how Socrates used relentless questioning to expose contradictions in his interlocutors' beliefs, drawing on examples from Plato's early dialogues like the Euthyphro and the Laches. The conversation covers the structure of the elenchus—from the initial question to the refutation and the resulting aporia—and discusses its purpose as a tool for ethical improvement rather than mere argumentative victory. Lucas explains how the method challenged Athenian assumptions about piety, courage, and justice, and why it earned Socrates both devoted followers and powerful enemies. The episode also touches on the limits of the elenchus and how later philosophers like Aristotle critiqued its purely negative approach. Along the way, the hosts consider a real-world example: whether a modern politician could survive Socratic questioning about their principles. This episode is a focused exploration of the technique that made Socrates the 'gadfly' of Athens, perfect for listeners who want to understand how philosophy worked in practice. #Socrates #Elenchus #Plato #Euthyphro #Laches #Apology #Aporia #SocraticMethod #AncientPhilosophy #Athens #GreekPhilosophy #CrossExamination #Virtue #Piety #Courage #HistoryOfPhilosophy #FexingoHistory #History Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]
