Origin:

The earliest hedonist should be the ancient Greek philosopher and Socrates' disciple Ali stipe.

I don't know much about his philosophy. His words and deeds are included in the works of another ancient Greek philosopher, Diogenēs Laertius. "He said that the purpose of life is to enjoy physical happiness under the best conditions, and happiness is the sum of happiness. ..... In his view, since there is a requirement, he has the right to meet this requirement, so as to realize the purpose of life-enjoyment. "

Theory:

Epicurus' happiness refers to "aponia" and "ataraxia". "Epicurus believes that happiness obtained by satisfying certain desires is not the purpose of life, because boredom will inevitably follow this happiness, thus making people deviate from his real purpose, that is, no pain.

In fact, there are many similarities between Epicurus' theory and Freud's theory. !
