cynical

Picture Athens in the fourth century BCE: Antisthenes is teaching philosophy at a gymnasium called Kynosarges, commonly glossed as “the Silver Dog.” His followers rejected wealth, status, elegant clothes, and nearly every social nicety, so people began calling them kunikoi—“doglike”—whether the nickname came from the building or from their famously dog-like behavior. Diogenes, the school’s most notorious member, reportedly slept in a tub and treated public convention as something to bark at rather than obey. By the 1590s, English cynic could mean a sneering, sarcastic person; cynical followed by the 1660s, shifting from a name for a philosophical lifestyle to a suspicion that everyone else is secretly selfish. So when someone makes a bitter joke about a charity, a wedding, or human goodness itself, the ancient dog is still there: not merely growling at society, but asking whether its fine-looking motives are worth believing.
