cynic
skeptic / pessimist / philosopher
Noun
pl: cynics
This term describes a mindset of deep skepticism regarding human sincerity. It carries a negative connotation of bitterness or jadedness, suggesting that the speaker has given up on the possibility of genuine altruism. In modern usage, it often describes someone who dismisses idealism as naive. Historically, the word refers to the Cynics of ancient Greece. While the modern meaning focuses on distrust, the original philosophical sense emphasized a rigorous rejection of luxury and social status in favor of a virtuous, natural life.
