Cynic
The Cynics (, ) were an important group of philosophers from the ancient school of Cynicism. Their philosophy taught that the purpose of life was to live a life of Virtue in agreement with Nature.  This meant rejecting all the usual desires for wealth, power, health, and fame, and by living a life free from all possessions. People are reasoning creatures. They could therefore gain happiness by rigorous training and by living in a way which was natural for humans. They believed that the world belonged equally to everyone, and that suffering was caused by false judgments of what was valuable and by the worthless customs and conventions which surrounded society. Many of these thoughts were later absorbed into Stoicism.
