Or if it be uprightness you love, why, virtues are the fruit of her labours, since it is she who teaches temperance and prudence, justice and fortitude; nothing in life is more useful for human beings. (Wisdom 8:7)
Prudence is a virtue of the intellect; Justice is a virtue of the will; Fortitude and Temperance are virtues of emotions.
Virtues are firm attitudes, stable dispositions, habitual perfections of intellect and will that govern our actions, order our passions, and guide our conduct according to reason and faith. They make possible ease, self-mastery, and joy in leading a morally good life. The virtuous man is he who freely practices the good.
