Cynicism is an attitude characterized by a general distrust of the motives of "others". A cynic may have a general lack of faith or hope in people motivated by ambition, desire, greed, gratification, materialism, goals, and opinions that a cynic perceives as vain, unobtainable, or ultimately meaningless and therefore deserving of ridicule or admonishment. The term originally derives from the ancient Greek philosophers, the Cynics, who rejected conventional goals of wealth, power, and honor. They practiced shameless nonconformity with social norms in religion, manners, housing, dress, or decency, instead advocating the pursuit of virtue in accordance with a simple and natural way of life.
