Hedonism

Hedonism is a school of thought that argues that pleasure is the primary or most important intrinsic good. A hedonist strives to maximize net pleasure (pleasure minus pain).

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.
