Noble lies, spicy replies
The Popper Principle
Popper vs Plato: Did the 'noble lie' pave the road to tyranny? Fans cheer, scholars fume
TLDR: Popper blasted Plato’s ideal city as a seed of tyranny and championed testing ideas by trying to disprove them. The comments exploded: fans praised falsifiability and modern warnings about technocracy, while scholars shot back that Popper misread Plato’s Republic as politics instead of metaphor—stakes that feel urgent today.
Karl Popper’s big swing—claiming that Plato’s dream city helped inspire real-world tyrants—sent the comments into gladiator mode. Fans rallied around Popper as the hero of fallibilism (testing ideas by trying to disprove them), with one reader cheering that language study itself got better when “hypotheses were truly falsifiable.” Others waved Popper’s famous Paradox of Tolerance like a banner and dropped a book-club summons to David Deutsch’s The Beginning of Infinity.
But the Plato defense squad showed up swinging. One skeptic called Popper’s reading of the Republic “trash,” insisting Plato’s rigid city was a metaphor for the soul, not a government starter kit. Meanwhile, a doom-prophet warned we’re swapping ancient philosopher-kings for modern technocrats—today’s “noble lie” in a lab coat—arguing Popper’s warnings hit hardest right now. Another commenter tossed in a wildcard rec: “If you like Popper, try Software and Mind,” which the thread promptly turned into side-quest discourse.
The vibe? Popper stans vs. Plato purists, with bystanders making memes about “philosopher-kings vs. keyboard kings” and wondering if “noble lies” was just the OG fake news. Through it all, Popper’s wartime anger and tragedy shadowed the debate, giving the takedown of Plato a raw urgency that even critics couldn’t ignore. For some, he’s saving science and politics; for others, he’s picking a fight with a straw-Plato—and the comments are loving every punch.
Key Points
- •Karl Popper advanced fallibilism, asserting that science progresses through attempts to falsify theories rather than prove them.
- •In the 1930s, Popper extended his analysis to political theory in response to rising totalitarianism, leaving Vienna for Christchurch to teach at the University of New Zealand.
- •In The Open Society and Its Enemies (published just before his 1945 return to Europe), Popper argued modern totalitarian ideologies draw on ancient roots, particularly in Plato’s thought.
- •Popper criticized Plato’s Republic for proposing a rigidly stratified society led by philosopher‑kings who sustain control through “noble lies,” including myths about innate metals and the banishment of poets.
- •The article situates Popper’s harsher tone in the personal tragedy of the Holocaust, noting 16 members of his family were killed in death camps.
