A virtue is a habitual disposition to do good.  Among all the virtues, there are four that play a pivotal role and accordingly are called cardinal.

• Prudence, which disposes the practical reason to discern in every circumstance one’s true good and to choose the right means for achieving it.
• Justice, which consists in the firm and constant will to give God and neighbor their due.
• Fortitude, which ensures firmness in difficulties and constancy in the pursuit of the good.
• Temperance, which moderates the attraction of the pleasures of the senses and provides balance in the use of created goods.
