Relation to morality
Philosophy of happiness is often discussed in conjunction with ethics.^[36] Traditional European societies, inherited from the Greeks and from Christianity, often linked happiness with morality, which was concerned with the performance in a certain kind of role in a certain kind of social life.^[37]
Happiness remains a difficult term for moral philosophy. Throughout the history of moral philosophy, there has been an oscillation between attempts to define morality in terms of consequences leading to happiness and attempts to define morality in terms that have nothing to do with happiness at all.^[38]
Connections between happiness and morality have been studied in a variety of ways in psychology. Empirical research suggests that laypeople's judgments of a person's happiness in part depend on perceptions of that person's morality, suggesting that judgments of others' happiness involve moral evaluation.^[39] A large body of research also suggests that engaging in prosocial behavior can increase happiness.^[40][41][42]
Aristotle
Aristotle described eudaimonia (Greek: εὐδαιμονία) as the goal of human thought and action. Eudaimonia is often translated to mean happiness, but some scholars contend that "human flourishing" may be a more accurate translation.^[43] Aristotle's use of the term in Nicomachiean Ethics extends beyond the general sense of happiness.^[44]
In the Nicomachean Ethics, written in 350 BCE, Aristotle stated that happiness (also being well and doing well) is the only thing that humans desire for their own sake, unlike riches, honour, health or friendship. He observed that men sought riches, or honour, or health not only for their own sake but also in order to be happy.^[45] For Aristotle the term eudaimonia, which is translated as 'happiness' or 'flourishing' is an activity rather than an emotion or a state.^[46] Eudaimonia (Greek: εὐδαιμονία) is a classical Greek word consists of the word "eu" ("good" or "well-being") and "daimōn" ("spirit" or "minor deity", used by extension to mean one's lot or fortune). Thus understood, the happy life is the good life, that is, a life in which a person fulfills human nature in an excellent way. Specifically, Aristotle argued that the good life is the life of excellent rational activity. He arrived at this claim with the "Function Argument". Basically, if it is right, every living thing has a function, that which it uniquely does. For Aristotle human function is to reason, since it is that alone which humans uniquely do. And performing one's function well, or excellently, is good. According to Aristotle, the life of excellent rational activity is the happy life. Aristotle argued a second-best life for those incapable of excellent rational activity was the life of moral virtue.^[47] The key question Aristotle seeks to answer is "What is the ultimate purpose of human existence?" a lot of people are seeking pleasure, health, and a good reputation. It is true that those have a value, but none of them can occupy the place of the greatest good for which humanity aims. It may seem like all goods are a means to obtain happiness, but Aristotle said that happiness is always an end in itself.^[48]
