"...As opposed to the speculative philosophy of figures such as Plato and Aristotle, Cynical philosophy was a lived philosophy. The Cynics developed philosophical theories as a means to living well, and they disregarded the majority of abstract philosophy.
The Cynics argued against a superficial life, in favor of “a life lived in accord with nature.” For them, living in accordance with nature meant following a path of self-sufficiency, freedom, and lucid reasoning. They believed that social conventions had the ability to hinder the “good life,” and could lead to corruption by, “compromising freedom and setting up a code of conduct that is opposed to nature and reason.” Kinda sounds like the hippy at the house party if you ask me…
