Diogenes of Sinope was a Greek philosopher and one of the most famous figures of Cynicism. Born in Sinope around 412 or 404 BCE, he is known for his ascetic lifestyle and belief in living in accordance with nature. Diogenes rejected societal norms and materialism, often using provocative actions to illustrate his philosophy. He is best known for carrying a lantern in broad daylight, claiming to be searching for an honest man. Diogenes lived in a large ceramic jar and had little regard for social etiquette, famously challenging the values of his contemporaries, including Plato and Aristotle.
