Diogenes Posting refers to a genre of internet memes centered around the ancient Greek philosopher Diogenes of Sinope, the founder of Cynicism. Known for his public defiance of social norms, living in a large ceramic jar, and his biting wit, Diogenes became a modern internet icon for his radical authenticity. The memes frequently reference his legendary encounters, such as telling Alexander the Great to move out of his sunlight or crashing Plato’s lecture with a plucked chicken to mock his definition of a human as a 'featherless biped.' These memes utilize various historical paintings and modern illustrations to celebrate minimalism, truth-telling, and the humor found in pointing out societal absurdities.
