For the Cynics, the purpose of life is to live in virtue, in agreement with nature. As reasoning creatures, people can gain happiness by rigorous training and by living in a way which is natural for themselves, rejecting all conventional desires for wealth, power, sex, and fame. Instead, they were to lead a simple life free from all possessions.
我们知道，犬儒主义是古希腊的一个哲学流派，其代表人物是西诺普的狄奥根尼（Diogenes of Sinope）。这派哲学主张清心寡欲，鄙弃俗世的荣华富贵，力倡回归自然（这使人想起老庄哲学，想起某些魏晋名士）。据说狄奥根尼本人住在一个桶里（又有一说是住在瓮里），以讨饭为生。有人讥笑他活得象条狗，他却不恼。“犬儒”之称由此得名。关于狄奥根尼，有段故事很著名，一天，亚历山大御驾亲临，前来探望正躺在地上晒太阳的狄奥根尼，问他想要什么恩赐；狄奥根尼回答说：“只要你别挡住我的太阳。”
The ascetic orders of Christianity also had direct connection with the Cynics, as can be seen in the wandering mendicant monks of the early church who in outward appearance, and in many of their practices differed little from the Cynics of an earlier age.
