Explanation: Diogenes of Sinope was an ancient Greek philosopher known for his radical iconoclasm, living in an upturned wine barrel with stray dogs and violating and mocking social norms at every turn. He was sometimes referred to as a dog or dog-like (from which we get the term ‘Cynic’), a comparison that he embraced, as he believed that man generally benefitted from living in a state close to nature, as free from superfluous comforts and ideas (like ‘manners’) as possible.

Supposedly, once at a banquet he was taunted and thrown a bone, to which he responded by urinating on his taunters, as a dog might.

Despite the humor of such stories, Diogenes was hugely influential on both the Cynic and Stoic schools of Greek philosophy. His iconoclasm and wit bely a then-radical and robust worldview depicting a happy life possible without excessive luxury - a novel idea in aristocratic Ancient Greece!
