"Epicurus asserted that philosophy's purpose is to attain as well as to help others attain happy (eudaimonic), tranquil lives characterized by ataraxia (peace and freedom from fear) and aponia (the absence of pain). He advocated that people were best able to pursue philosophy by living a self-sufficient life surrounded by friends." [0]
"Epicurus distinguishes between three types of desires: natural and necessary, natural but unnecessary, and vain and empty. Natural and necessary desires include the desires for food and shelter. These are easy to satisfy, difficult to eliminate, bring pleasure when satisfied, and are naturally limited. Going beyond these limits produces unnecessary desires, such as the desire for luxury foods. Although food is necessary, luxury food is not necessary. Correspondingly, Epicurus advocates a life of hedonistic moderation by reducing desire, thus eliminating the unhappiness caused by unfulfilled desires. Vain desires include desires for power, wealth, and fame. These are difficult to satisfy because no matter how much one gets, one can always want more. These desires are inculcated by society and by false beliefs about what we need. They are not natural and are to be shunned" [0]
