Virtue

A virtue (Latin: virtus) is a trait of excellence, including traits that may be moral, social, or intellectual. The cultivation and refinement of virtue is held to be the "good of humanity" and thus is valued as an end purpose of life or a foundational principle of being. In human practical ethics, a virtue is a disposition to choose actions that succeed in showing high moral standards: doing what is said to be right and avoiding what is wrong in a given field of endeavour, even when doing so may be unnecessary from a utilitarian perspective. When someone takes pleasure in doing what is right, even when it is difficult or initially unpleasant, they can establish virtue as a habit. Such a person is said to be virtuous through having cultivated such a disposition. The opposite of virtue is vice.

Other examples of this notion include the concept of merit in Asian traditions as well as De (Chinese 德).

The ancient Romans used the Latin word virtus (derived from vir, their word for man) to refer to all of the "excellent qualities of men, including physical strength, valorous conduct, and moral rectitude". The French words vertu and virtu came from this Latin root. The word virtue "was borrowed into English in the 13th century".

Maat (or Ma'at) was the ancient Egyptian goddess of truth, balance, order, law, morality, and justice. The word maat was also used to refer to these concepts. Maat was also portrayed as regulating the stars, seasons, and the actions of both mortals and the deities. The deities set the order of the universe from chaos at the moment of creation. Her (ideological) counterpart was Isfet, who symbolized chaos, lies, and injustice.

The four classic cardinal virtues are:

This enumeration is traced to Greek philosophy and was listed by Plato who also added piety (ὁσιότης, hosiotēs) and replaced prudence with wisdom. Some scholars consider either of the above four virtue combinations as mutually reducible and therefore not cardinal.

It is unclear whether Plato subscribed to a unified view of virtues. In Protagoras and Meno he states that the separate virtues cannot exist independently and offers as evidence the contradictions of acting with wisdom, yet in an unjust way; or acting with bravery (fortitude), yet without wisdom. The narrative in the Meno commences with the eponymous character asking about virtue, but when Socrates asks him "What is virtue?", he replies with a list of virtues displayed in different ways.

In his Nicomachean Ethics, Aristotle defined a virtue as a point between a deficiency and an excess of a trait. The point of greatest virtue lies not in the exact middle, but at a golden mean sometimes closer to one extreme than the other. This golden mean obtains at a desirable middle between excess and deficiency. For Aristotle, the desirableness of the trait at the golden mean—that which makes it a virtue—consists in its disposition to be "chosen under the proper guidance of reason". That is, in its disposition to foster human flourishing, a state defined with respect to human nature conceived teleologically, or as an end to be realized instead of a descriptive fact to be understood.
