Cardinal virtues
Augustine of Hippo, discussing the morals of the church, described them:
The "cardinal" virtues are not the same as the three theological virtues: Faith, Hope and Charity (Love), named in 1 Corinthians 13. 
"And now these three remain: faith, hope and love. But the greatest of these is love."
Because of this reference, a group of seven attributes is sometimes listed by adding the four cardinal virtues (prudence, temperance, fortitude, justice) and three theological virtues (faith, hope, charity).
Together, they comprise what is known as the seven virtues. While the first four date back to Greek philosophers and were applicable to all people seeking to live moral lives, the "theological virtues" appear to be specific to Christians as written by Paul in The New Testament.
Ethics
Aristotle (384–323 BC) posited an ethical system that may be termed "virtuous". In Aristotle's view, when a person acts in accordance with virtue this person will do good and be content. Unhappiness and frustration are caused by doing wrong, leading to failed goals and a poor life. Therefore, it is imperative for people to act in accordance with virtue, which is only attainable by the practice of the virtues in order to be content and complete. Happiness was held to be the ultimate goal. All other things, such as civic life or wealth, were only made worthwhile and of benefit when employed in the practice of the virtues. The practice of the virtues is the surest path to happiness.
