Joy
"1) All things, rational and irrational, aim at pleasure; things aim at what they believe to be good; a good indication of what the chief good is would be the thing that most things aim at. 2) Similarly, pleasure's opposite—pain—is universally avoided, which provides additional support for the idea that pleasure is universally considered good. 3) People don't seek pleasure as a means to something else, but as an end in its own right. 4) Any other good that you can think of would be better if pleasure were added to it, and it is only by good that good can be increased. 5) Of all of the things that are good, happiness is peculiar for not being praised, which may show that it is the crowning good."
- Eudoxus of Cnidus, born circa 390 BCE in Knidos, Caria, Achaemenid Empire (on the land of present day Turkey)
