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.

Christopher Peterson and Martin Seligman, two leading researchers in positive psychology, recognizing the deficiency inherent in psychology's tendency to focus on dysfunction rather than on what makes a healthy and stable personality, set out to develop a list of "Character Strengths and Virtues". After three years of study, 24 traits (classified into six broad areas of virtue) were identified, having "a surprising amount of similarity across cultures and strongly indicat[ing] a historical and cross-cultural convergence." These six categories of virtue are courage, justice, humanity, temperance, transcendence, and wisdom. Some psychologists suggest that these virtues are adequately grouped into fewer categories; for example, the same 24 traits have been grouped into simply: Cognitive Strengths, Temperance Strengths, and Social Strengths.
