Aristippus explained that hedonistic ethical egoism is the concept that everyone has the right to do everything they can to attain the greatest amount of pleasure possible to them. He also said that everyone's pleasure should far surpass their amount of pain. He came to these conclusions after sitting at Socrates’ feet and hearing his musings and stimulating questions.
Socrates never made an explicit stand against hedonism itself. He stated that knowledge is virtue (which is what brings happiness and fulfillment). He was more interested in concepts such as, “Know Thyself” and “The unexamined life is not worth living.” This could be seen as the very opposite of unthinking hedonism, in which people satisfy their every whim and desire without anything else in mind besides having fun.
Frolicking around in an endless party doesn’t always end well, though. Ultimately, the fun will go away, and then what will we be left with if we don’t know who we truly are in the depths of our heart, inner-mind, and Soul? Gorging on food and drink, sex and riotous living is actually the opposite of what Socrates was pointing to if we want inner peace and contentment.
In a sense, we can determine that Socrates thought hedonism was self-defeating. If we are totally self-interested and seek nothing but pleasure, we are bound to fail because the appetite for pleasure is insatiable. It’s called the “paradox of hedonism.” So, although Socrates doesn’t think hedonism is bad, he just saw it as self-defeating and would never bring true happiness.
