Hedone
Hedone is the Greek word meaning "pleasure". It was an important concept in Ancient Greek philosophy, especially in the Epicurean school. It is also the root of the English word "hedonism".
In Greek mythology, Hedone is personified as a goddess of pleasure, enjoyment, and delight, as the daughter born from the union of Eros and Psyche. She was associated more specifically with sensual pleasure. Her opposites were the Algea, personifications of pain. Her equivalent in Roman mythology is Voluptas. There is no evidence that she was ever the object of cult worship.
Aristotle's Hēdonē
Aristotle identified it as one of the two elements or components of pathe, with the other being lype or pain. Aristotle described pathe in these words: "Let the emotions be all those things on account of which people change their minds and differ in regard to their judgments, and upon which attend pain and pleasure."Hēdonē, is part of Aristotle's account of virtue, such that 'pleasure' is said to reveal a person's character. It is good if it is a consequence of a virtuous life – as opposed to the position Aristippus, who holds that hēdonē is "wholly good". An example is the concept of proper pleasure or oikeia hedone, which Aristotle discusses in /Poetics/ and considers a process of restoration. Martin Heidegger interprets Aristotelian hēdonē: that pleasure is a movement of the soul and that tranquility arises from it.
