Prudence - Article 7

Article 7. Whether it belongs to prudence to find the mean in moral virtues?

Objection 1. It would seem that it does not belong to prudence to find the mean in moral virtues. For the achievement of the mean is the end of moral virtues. But prudence does not appoint the end to moral virtues, as shown above (Article 6). Therefore it does not find the mean in them. Objection 2. Further, that which of itself has being, would seem to have no cause, but its very being is its cause, since a thing is said to have being by reason of its cause. Now "to follow the mean" belongs to moral virtue by reason of itself, as part of its definition, as shown above (5, Objection 1). Therefore prudence does not cause the mean in moral virtues. Objection 3. Further, prudence works after the manner of reason. But moral virtue tends to the mean after the manner of nature, because, as Tully states (De Invent. Rhet. ii, 53), "virtue is a habit like a second nature in accord with reason." Therefore prudence does not appoint the mean to moral virtues. On the contrary, In the foregoing definition of moral virtue (5, Objection 1) it is stated that it "follows a mean appointed by reason . . . even as a wise man decides." I answer that, The proper end of each moral virtue consists precisely in conformity with right reason. For temperance intends that man should not stray from reason for the sake of his concupiscences; fortitude, that he should not stray from the right judgment of reason through fear or daring. Moreover this end is appointed to man according to natural reason, since natural reason dictates to each one that he should act according to reason. But it belongs to the ruling of prudence to decide in what manner and by what means man shall obtain the mean of reason in his deeds. For though the attainment of the mean is the end of a moral virtue, yet this mean is found by the right disposition of these things that are directed to the end. This suffices for the Reply to the First Objection. Reply to Objection 2. Just as a natural agent makes form to be in matter, yet does not make that which is essential to the form to belong to it, so too, prudence appoints the mean in passions and operations, and yet does not make the searching of the mean to belong to virtue. Reply to Objection 3. Moral virtue after the manner of nature intends to attain the mean. Since, however, the mean as such is not found in all matters after the same manner, it follows that the inclination of nature which ever works in the same manner, does not suffice for this purpose, and so the ruling of prudence is required.

Prudence - Article 6

Article 6. Whether prudence appoints the end to moral virtues?

Objection 1. It would seem that prudence appoints the end to moral virtues. Since prudence is in the reason, while moral virtue is in the appetite, it seems that prudence stands in relation to moral virtue, as reason to the appetite. Now reason appoints the end to the appetitive power. Therefore prudence appoints the end to the moral virtues. Objection 2. Further, man surpasses irrational beings by his reason, but he has other things in common with them. Accordingly the other parts of man are in relation to his reason, what man is in relation to irrational creatures. Now man is the end of irrational creatures, according to Polit. i, 3. Therefore all the other parts of man are directed to reason as to their end. But prudence is "right reason applied to action," as stated above (Article 2). Therefore all actions are directed to prudence as their end. Therefore prudence appoints the end to all moral virtues. Objection 3. Further, it belongs to the virtue, art, or power that is concerned about the end, to command the virtues or arts that are concerned about the means. Now prudence disposes of the other moral virtues, and commands them. Therefore it appoints their end to them. On the contrary, The Philosopher says (Ethic. vi, 12) that "moral virtue ensures the rectitude of the intention of the end, while prudence ensures the rectitude of the means." Therefore it does not belong to prudence to appoint the end to moral virtues, but only to regulate the means. I answer that, The end of moral virtues is human good. Now the good of the human soul is to be in accord with reason, as Dionysius declares (Div. Nom. iv). Wherefore the ends of moral virtue must of necessity pre-exist in the reason. Now, just as, in the speculative reason, there are certain things naturally known, about which is "understanding," and certain things of which we obtain knowledge through them, viz. conclusions, about which is "science," so in the practical reason, certain things pre-exist, as naturally known principles, and such are the ends of the moral virtues, since the end is in practical matters what principles are in speculative matters, as stated above (23, 07, ad 2; I-II, 13, 3); while certain things are in the practical reason by way of conclusions, and such are the means which we gather from the ends themselves. About these is prudence, which applies universal principles to the particular conclusions of practical matters. Consequently it does not belong to prudence to appoint the end to moral virtues, but only to regulate the means. Reply to Objection 1. Natural reason known by the name of "synderesis" appoints the end to moral virtues, as stated above (I, 79, 12): but prudence does not do this for the reason given above. This suffices for the Reply to the Second Objection. Reply to Objection 3. The end concerns the moral virtues, not as though they appointed the end, but because they tend to the end which is appointed by natural reason. On this they are helped by prudence, which prepares the way for them, by disposing the means. Hence it follows that prudence is more excellent than the moral virtues, and moves them: yet "synderesis" moves prudence, just as the understanding of principles moves science.

Prudence - Article 5

Article 5. Whether prudence is a special virtue?

It is distinct from and numbered among the other virtues, for it is written (Wisdom 8:7): "She teacheth temperance and prudence, justice and fortitude."

I answer that, Since acts and habits take their species from their objects, as shown above (I-II, 01, 3; I-II, 18, 2; I-II, 54, 2), any habit that has a corresponding special object, distinct from other objects, must needs be a special habit, and if it be a good habit, it must be a special virtue. Now an object is called special, not merely according to the consideration of its matter, but rather according to its formal aspect, as explained above (I-II, 54, 2, ad 1). Because one and the same thing is the subject matter of the acts of different habits, and also of different powers, according to its different formal aspects. Now a yet greater difference of object is requisite for a difference of powers than for a difference of habits, since several habits are found in the same power, as stated above (I-II, 54, 1). Consequently any difference in the aspect of an object, that requires a difference of powers, will "a fortiori" require a difference of habits. Accordingly we must say that since prudence is in the reason, as stated above (Article 2), it is differentiated from the other intellectual virtues by a material difference of objects. "Wisdom," "knowledge" and "understanding" are about necessary things, whereas "art" and "prudence" are about contingent things, art being concerned with "things made," that is, with things produced in external matter, such as a house, a knife and so forth; and prudence, being concerned with "things done," that is, with things that have their being in the doer himself, as stated above (I-II, 57, 4). On the other hand prudence is differentiated from the moral virtues according to a formal aspect distinctive of powers, i.e. the intellective power, wherein is prudence, and the appetitive power, wherein is moral virtue. Hence it is evident that prudence is a special virtue, distinct from all other virtues.

Prudence - Article 4

Article 4. Whether prudence is a virtue?

Gregory states (Moral. ii, 49) that prudence, temperance, fortitude and justice are four virtues.

I answer that, As stated above (I-II, 55, 3; I-II, 56, 1) when we were treating of virtues in general, "virtue is that which makes its possessor good, and his work good likewise." Now good may be understood in a twofold sense: first, materially, for the thing that is good, secondly, formally, under the aspect of good. Good, under the aspect of good, is the object of the appetitive power. Hence if any habits rectify the consideration of reason, without regarding the rectitude of the appetite, they have less of the nature of a virtue since they direct man to good materially, that is to say, to the thing which is good, but without considering it under the aspect of good. On the other hand those virtues which regard the rectitude of the appetite, have more of the nature of virtue, because they consider the good not only materially, but also formally, in other words, they consider that which is good under the aspect of good. Now it belongs to prudence, as stated above (1, ad 3; 3) to apply right reason to action, and this is not done without a right appetite. Hence prudence has the nature of virtue not only as the other intellectual virtues have it, but also as the moral virtues have it, among which virtues it is enumerated.

Prudence - Article 3

Article 3. Whether prudence takes cognizance of singulars?

The Philosopher says (Ethic. vi, 7) that "prudence does not deal with universals only, but needs to take cognizance of singulars also."

I answer that, As stated above (1, ad 3), to prudence belongs not only the consideration of the reason, but also the application to action, which is the end of the practical reason. But no man can conveniently apply one thing to another, unless he knows both the thing to be applied, and the thing to which it has to be applied. Now actions are in singular matters: and so it is necessary for the prudent man to know both the universal principles of reason, and the singulars about which actions are concerned.

Prudence - Article 2

Article 2. Whether prudence belongs to the practical reason alone or also to the speculative reason?

The Philosopher says (Ethic. vi, 5) that prudence is right reason applied to action. Now this belongs to none but the practical reason. Therefore prudence is in the practical reason only.

I answer that, According to the Philosopher (Ethic. vi, 5) "a prudent man is one who is capable of taking good counsel." Now counsel is about things that we have to do in relation to some end: and the reason that deals with things to be done for an end is the practical reason. Hence it is evident that prudence resides only in the practical reason.

St. Thomas on Prudence - Article 1

Ave Maria!  Let us grow in virtue for Our Virgin Queen Mary!  I think it is important to learn about the virtue we are focusing on so it will be in our thoughts.
- Jared

Article 1. Whether prudence is in the cognitive or in the appetitive faculty?

Augustine says (QQ. lxxxiii, qu. 61): "Prudence is the knowledge of what to seek and what to avoid."

I answer that, As Isidore says (Etym. x): "A prudent man is one who sees as it were from afar, for his sight is keen, and he foresees the event of uncertainties." Now sight belongs not to the appetitive but to the cognitive faculty. Wherefore it is manifest that prudence belongs directly to the cognitive, and not to the sensitive faculty, because by the latter we know nothing but what is within reach and offers itself to the senses: while to obtain knowledge of the future from knowledge of the present or past, which pertains to prudence, belongs properly to the reason, because this is done by a process of comparison. It follows therefore that prudence, properly speaking, is in the reason.
