By Dr. Brian Engelland, The Catholic Gentleman - In order to be honest, one must be practiced in the cardinal virtues, which include prudence, justice, courage, and moderation. Prudence allows us to keep confidential information confidential; justice allows us to present information with sensitivity and respect for others affected; courage allows us to admit our failings and faults; and moderation allows us to rein in our excesses and provide balance in our discussions.
