 Aquinas accepts the Platonic-Aristotelian thesis that there are four virtues which are cardinal, that is on which the moral life and all other virtues hinge or depend: prudentia, justice, courage, and temperantia. Each is a strategic element in one’s integrating of the good of practical reasonableness into one’s deliberations, choices and execution of choices (prudentia), in one’s dealings with others justice), and in integrating and governing one’s desires by genuine reasons (temperantia) and enabling one to face down intimidating obstacles (courage, fortitudo).
