Seven virtues
The "Catechism of the Catholic Church" defines virtue as "a habitual and firm disposition to do the good." Traditionally, the seven Christian virtues or heavenly virtues combine the four classical cardinal virtues of prudence, justice, temperance and courage (or fortitude) with the three theological virtues of faith, hope and charity. These were adopted by the Church Fathers as the seven virtues.
Courage
David Hume listed virtues into two categories in his work "A Treatise of Human Nature" as artificial virtues and natural virtues. Hume noted in the Treatise that courage is a natural virtue. In the Treatise's section "Of Pride and Humility, Their Objects and Causes", Hume clearly stated courage is a cause of pride: "Every valuable quality of the mind, whether of the imagination, judgment, memory or disposition; wit, good-sense, learning, courage, justice, integrity; all these are the cause of pride; and their opposites of humility".
