The 'Plato's Man' or 'Featherless Biped' meme stems from an ancient anecdote involving the philosophers Plato and Diogenes the Cynic. After Plato defined a human being as a 'featherless biped' to much acclaim, Diogenes famously plucked a chicken and brought it into the Academy, declaring, 'Behold! I’ve brought you a man.' This act of radical cynicism forced Plato to add 'with broad flat nails' to his definition. In modern internet culture, the meme is used to highlight technicalities, flawed logic, or to humorously deconstruct overly broad definitions by presenting a literal but absurd counter-example. It is a favorite among philosophy students and history buffs for its combination of high-brow context and low-brow execution.
