Hedonism is a school of thought that argues that
happiness are the primary or most important
intrinsic goods and the aim of human life.
 A hedonist strives to maximize net pleasure (pleasure minus
pain), but when having finally gained that pleasure, either through intrinsic or extrinsic goods, happiness remains stationary.
Ethical hedonism is the idea that all people have the right to do everything in their power to achieve the greatest amount of pleasure possible to them. It is also the idea that every person's pleasure should far surpass their amount of pain. Ethical hedonism is said to have been started by
Aristippus of Cyrene, a student of
Socrates. He held the idea that pleasure is the highest good.
Hedonism is a sub-philosophy of
utilitarianism, which says to act in a way that maximizes utility. Hedonists equate pleasure with utility and believe that pleasure is the master of all humankind, and acts as the ultimate life goal. Hedonists believe that there are only two motivators of human action, pleasure and pain, and that decisions should only be made to further our pleasurable experiences and minimize or completely eliminate our painful ones.
