Epic of Gilgamesh

 and the Icelandic Eddas, portray a set of values that suit the strong leader of a small tribe. Valour and success are the principal qualities of a hero, and are generally not constrained by moral considerations. Revenge and vendetta are appropriate activities for heros. The gods that appear in such epics are not defenders of moral values but are as capricious as forces of nature, and are to be feared and propitiated.

More strictly ethical claims are found occasionally in the literature of ancient civilizations that is aimed at lower classes of society. The Sumerian Farmer's Almanac

, defends an ethical theory that the Greeks found paradoxical, that it is better to suffer injustice than to do it. That is because the doing of evil damages the soul, which is the highest part of humans. In the Republic, Socrates is challenged to defend the view that we have reasons to be moral that do not come from rational self-interest, in response to Glaucon's arguments in Book 1. The Republic develops the view that being a good person in an ethical sense involves achieving internal harmony of the parts of the soul. However, Plato's ethical ideal, as expressed in the Republic, still has much in common with the Homeric conception of the leader of a tribe or city: the successful running of the city and the internal harmony of the citizen who runs it is the main ethical aim, and there is little mention in Plato of any strictly moral obligations the ruler may be under.

Aristotle's ethics
Aristotelian ethics
Ethics as a subject begins with the works of Aristotle. In its original form, this subject is concerned with the question of virtue of character , or in other words having excellent and well-chosen habits. The acquisition of an excellent character is in turn aimed at living well and eudaimonia, a...

 is based on the ideal of eudaimonia, variously translated as "happiness," "prosperity," "flourishing," or "success." A "great-souled" citizen who lives a life of virtue can expect to achieve eudaimonia, which Aristotle argues is the highest good for man. Following Plato, Aristotle gives a significant role in moral life the virtues, fixed habits of behavior that lead to good outcomes; the main virtues are courage

 and temperance. The highest form of life is, however, purely intellectual activity.

Later Greek schools of philosophy, such as the Epicureans and Stoics, debated the conditions of the "good life." The Epicureans emphasised the quiet enjoyment of pleasures, free of fear, while the Stoics praised the life of reason lived in accordance with nature.

A theme of Ancient Greek ethics then is the role of the virtuous life in achieving eudaimonia, or the good life; and Aristotle, Epicurus and the Stoics all argued that virtue was necessary for happiness, albeit in different ways and with different conceptions of those terms.

: correct moral rules are those we could will everyone to adopt.

Kant's philosophy marks a number of important conceptual shifts in philosophical thinking about ethics. Kant argues that questions about happiness should not be a focus in ethical thought, because ethics should be universal while happiness may involve very different modes of life for different individuals. He also believed this approach was necessary if an ethical theory was to avoid becoming 'heteronomous'; that is, locating the source of proper moral motivation outside of properly moral concerns.
