Cynicism, founded by Diogenes of Sinope, rejected social norms and material possessions. This philosophy promoted a simple life, self-sufficiency, and living according to nature. Cynics challenged societal conventions through provocative actions and speeches.

Cynicism's influence extended beyond its time, inspiring later philosophical schools like Stoicism. Its emphasis on cosmopolitanism, free speech, and anti-materialism laid the groundwork for ideas that continue to resonate in modern discussions of ethics and social criticism.
