Cynicism is an attitude or state of mind characterized by a general distrust of others' apparent motives believing that they are selfish in nature and/or displaying that themselves. A cynic may have a general lack of faith or hope in the human race or in individuals with desires, hopes, opinions, or personal tastes that a cynic perceives as unrealistic or inappropriate, and therefore deserving of ridicule or admonishment.
