Moral Theology. Charles J. Callan
The intellectual virtues, except prudence, are not perfect virtues, since, While they make an act good, they do not necessarily make the agent good. A man may have great knowledge about morality, or be able to produce excellent works of art, and at the same time be not virtuous, or have no love for his work.
148. Prudence is an intellectual virtue, since it resides in the intellect; but it is also classed among the moral virtues, since its object is the direction of human acts to their right end.
149. The moral virtues are those habits that perfect the will and the sensitive appetite with reference to their immediate and respective objects; that is, they are habits concerned with acts as means to the Last End. They make the act good, and make good also him who performs it; and they are thus superior as virtues to the intellectual habits.
150. There are four principal moral virtues: (a) in the intellect there is prudence, which guides all the actions and passions by directing the other moral virtues to what is good according to reason; (b) in the will there is justice, which inclines a person to make his actions accord with what he owes to others; (c) in the irascible appetite is fortitude, which subjects to reason the passions that might withdraw from good, such as fear of dangers and labors; (d) in the concupiscible appetite is temperance, which represses the motions of passions that would impel one to some sensible good opposed to reason.
These four virtues are also called cardinal virtues, because all the other moral virtues hinge on them.
151. The theological virtues are those that perfect the intellect and the will with reference to God, their ultimate, supernatural object. They are three: (a) faith, which is a virtue infused into the intellect, giving man supernatural truths that are perceived by a divine light; (b) hope, which is a virtue infused into the will, enabling man to tend towards the supernatural destiny disclosed by faith as towards an end possible of attainment; (c) charity, which is a virtue infused into the will, uniting man's affections to the object of his hope and transforming him into its likeness.
152. Causes of Virtues.—The causes of virtue are three: (a) nature, which is the cause of the inchoative intellectual and moral virtues, that is, of the theoretical and practical principles that are naturally known, and of the inclinations to virtue that arise from an individual's bodily constitution; (b) practice, which is the cause of perfected intellectual and moral virtues, that is, of the good habits that are formed by repeated acts (e.g., knowledge obtained through study, temperance fixed in the character through continued effort); (c) infusion from on high, which is the cause of the virtues that surpass nature (i.e., of the theological virtues and of the moral virtues that are concerned with our acts as ordered to the supernatural).
153. Properties of the Virtues.—From the definition of virtue given above certain properties result.
(a) Since a virtue makes conduct agree with a certain fixed standard, it does not allow of excess or defect. Hence, virtue follows the golden mean.
(b) Since the other moral virtues would go to extremes without the guidance of prudence, and since prudence would not judge aright without the right dispositions of the other virtues, it follows that the four moral virtues, at least in their perfect state, must always be together. And because charity is the fulfillment of the whole law, he who has charity has also all the other infused virtues.
(c) Since the virtues are directed towards objects of varying degrees of excellence, and since they are habits, and are capable of increase and decrease (137 sqq.), it follows that both virtues of different species, and those of the same species, are or may be unequal.
(d) Since some of the virtues imply conditions that will not exist in the life to come, it follows that these virtues will be somewhat changed in the blessed. Thus, temperance, which subdues the rebellion of the passions, will not be exercised in heaven, where the passions do not rebel.
154. The golden mean is found differently in different virtues.
(a) In the case of justice, the mean is determined by an external object that is invariable, since justice gives what is due to others, neither more nor less; in the case of fortitude and temperance the mean is determined by prudent judgment and is not invariable, since these two virtues are concerned with the regulation of the internal passions according to conditions of individuals and circumstances. Thus, a debt of ten dollars remains the same whether the debtor is rich or poor, whether the creditor needs it or not. But a glass of liquor, which would be just enough for one who was well, might be far too much for him when he was sick; and a danger which a man might be expected to encounter, might be too much for a woman or a boy.
(b) The mean of the intellectual and speculative virtues is the agreement with objective truth, as lying between the extremes of false affirmation and false negation. The mean of the practical virtue of prudence, as regulating the moral virtues, is right reason, considered as directive of the desires and conduct so as to avoid excess and defect.
(c) The theological virtues have no mean, as far as their object is concerned, since God, being infinite in truth, power and goodness, cannot be believed in, hoped in, or loved too much. By reason of their subject, however, these virtues have a mean, since it is possible for one to exceed, for example, in hope by presumptuously expecting what is not due to one's condition.
155. Without charity one may possess certain other virtues. (a) Thus, one may have the natural or acquired moral virtues, as is the case with many pagans, but such virtues are imperfect, since they do not direct their subject to the Supernatural End of man; (b) one may have the supernatural or infused virtues of faith and hope, as is the case with Christians who are not in the state of grace. Even such faith and hope are imperfect virtues, and are not meritorious.
156. Considered precisely as virtues (cfr. Article on Hope), the three groups rank as follows: (a) the theological virtues are the most excellent, since they deal directly with man's supernatural end; (b) By reason of their object, universal truth, the intellectual virtues are superior to the moral virtues, which are concerned with particular goods; (c) the moral virtues, nevertheless, are more perfect as virtues, for, so considered in the order of action, in perfecting the appetites, they are more properly principles of action.
157. The highest of the virtues within each group are the following:
(a) Charity is greater than faith and hope, since it implies union with its objects, while the other two imply a certain distance from their object;
(b) Justice is superior to fortitude and temperance, since it deals with actions by which man is rightly ordered, both as to himself and as to others, while the others deal with the passions and the right disposition of man as to himself. The order of the moral virtues is: prudence, which is the guide of the others; justice, which deals with man's actions and orders him rightly, both as to himself and as to others; fortitude, which governs the passions, even when life and death are the issues; temperance, which governs the passions in affairs of less importance;
(c) The chief of the intellectual virtues is wisdom, which considers the supreme cause of things, and therefore judges the other virtues of the intellect.
158. In the blessed the virtues will remain, but changed in some respects. (a) Thus, the rectitude of soul contained in the moral virtues will endure, but there will be no rebellious passions to overcome, no dangers to oppose, no debts of justice to be discharged, as in this life; (b) the intellectual virtues acquired in this life will remain, but the soul separated from the body will not employ sense images as in its earthly existence; (c) faith and hope will give place to vision and realization, but charity will never fall away.
159. The Complements of the Virtues.—The virtues are habits that supply the soul with an internal guide (prudence), and with inclinations to follow its direction (moral virtues). But there is also a higher Guide who speaks to the soul, and it is necessary that the inclinations of virtue be carried out in a suprahuman mode. Hence, the virtues are completed by certain adjuncts. These are: (a) the Gifts of the Holy Ghost, which are habits infused into the soul, making it sensitive to the guidance of the Holy Spirit and docile under His direction; (b) the Fruits of the Holy Ghost, which are acts that grow out of the virtues and have a special spiritual sweetness attached to them; (c) the Beatitudes, which are activities of special excellence having
