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.
Courage
In "Beyond Good and Evil", Friedrich Nietzsche describes master–slave morality, in which a noble man regards himself as a "determiner of values;" one who does not require approval, but passes judgment. Later, in the same text, he lists man's four virtues as "courage, insight, sympathy, and solitude," and goes on to emphasize the importance of courage: "The great epochs of our life are the occasions when we gain the courage to re-baptize our evil qualities as our best qualities."
