The intellectual virtue that guides practical reason to discern our true good in every circumstance and to choose the right means of achieving it. It involves the ability to judge correctly what is right and what is wrong in any given situation. It allows an individual to apply moral principles to concrete cases without error and overcome doubts about the good to be done and the evil to be avoided. For instance, a person exercising this virtue might carefully consider the consequences of a significant financial investment before committing to it, weighing potential benefits against possible risks.
Its significance lies in its role as the “charioteer of the virtues,” directing all other moral virtues toward their proper ends. Without it, courage might become recklessness, justice might become legalism, temperance might become repression, and faith might become fanaticism. Historically, it has been considered essential for effective leadership, responsible decision-making, and the cultivation of a morally sound character. Its development allows individuals to navigate the complexities of life with wisdom and integrity, contributing to both personal flourishing and the common good.
