Virtue
Philosophers throughout the ages have written their ideas about what they think virtue is.  The Ancient Greek philosophers from Plato onwards said that virtue consisted of four things: Justice, Courage, Wisdom, and Moderation.  In the Christian religion the three virtues  were Faith, Hope and Charity.  These are mentioned in the Bible in the First Epistle to the Corinthians chapter 13 verse 13.  These virtues are also very important in the Judaic and Muslim traditions.
