Summa Theologica

We must, in due sequence, consider the subjective parts of prudence. And since we have already spoken of the prudence with which a man rules himself (Q[47], seqq.), it remains for us to discuss the species of prudence whereby a multitude is governed. Under this head there are four points of inquiry:

(1) Whether a species of prudence is regnative?

(2) Whether political and (3) domestic economy are species of prudence?

(4) Whether military prudence is?

Objection 1: It would seem that regnative should not be reckoned a species of prudence. For regnative prudence is directed to the preservation of justice, since according to Ethic. v, 6 the prince is the guardian of justice. Therefore regnative prudence belongs to justice rather than to prudence.

Objection 2: Further, according to the Philosopher (Polit. iii, 5) a kingdom [regnum] is one of six species of government. But no species of prudence is ascribed to the other five forms of government, which are "aristocracy," "polity," also called "timocracy" [*Cf. Ethic. viii, 10], "tyranny," "oligarchy" and "democracy." Therefore neither should a regnative species be ascribed to a kingdom.

Objection 3: Further, lawgiving belongs not only to kings, but also to certain others placed in authority, and even to the people, according to Isidore (Etym. v). Now the Philosopher (Ethic. vi, 8) reckons a part of prudence to be "legislative." Therefore it is not becoming to substitute regnative prudence in its place.

On the contrary, The Philosopher says (Polit. iii, 11) that "prudence is a virtue which is proper to the prince." Therefore a special kind of prudence is regnative.

I answer that, As stated above (Q[47], AA,10), it belongs to prudence to govern and command, so that wherever in human acts we find a special kind of governance and command, there must be a special kind of prudence. Now it is evident that there is a special and perfect kind of governance in one who has to govern not only himself but also the perfect community of a city or kingdom; because a government is the more perfect according as it is more universal, extends to more matters, and attains a higher end. Hence prudence in its special and most perfect sense, belongs to a king who is charged with the government of a city or kingdom: for which reason a species of prudence is reckoned to be regnative.

Reply to Objection 1: All matters connected with moral virtue belong to prudence as their guide, wherefore "right reason in accord with prudence" is included in the definition of moral virtue, as stated above (Q[47], A[5], ad 1; FS, Q[58], A[2], ad 4). For this reason also the execution of justice in so far as it is directed to the common good, which is part of the kingly office, needs the guidance of prudence. Hence these two virtues—prudence and justice—belong most properly to a king, according to Jer. 23:5: "A king shall reign and shall be wise, and shall execute justice and judgment in the earth." Since, however, direction belongs rather to the king, and execution to his subjects, regnative prudence is reckoned a species of prudence which is directive, rather than to justice which is executive.

Reply to Objection 2: A kingdom is the best of all governments, as stated in Ethic. viii, 10: wherefore the species of prudence should be denominated rather from a kingdom, yet so as to comprehend under regnative all other rightful forms of government, but not perverse forms which are opposed to virtue, and which, accordingly, do not pertain to prudence.

Reply to Objection 3: The Philosopher names regnative prudence after the principal act of a king which is to make laws, and although this applies to the other forms of government, this is only in so far as they have a share of kingly government.

Objection 1: It would seem that political prudence is not fittingly accounted a part of prudence. For regnative is a part of political prudence, as stated above(A[1]). But a part should not be reckoned a species with the whole. Therefore political prudence should not be reckoned a part of prudence.

Objection 2: Further, the species of habits are distinguished by their various objects. Now what the ruler has to command is the same as what the subject has to execute. Therefore political prudence as regards the subjects, should not be reckoned a species of prudence distinct from regnative prudence.

Objection 3: Further, each subject is an individual person. Now each individual person can direct himself sufficiently by prudence commonly so called. Therefore there is no need of a special kind of prudence called political.

On the contrary, The Philosopher says (Ethic. vi, 8) that "of the prudence which is concerned with the state one kind is a master-prudence and is called legislative; another kind bears the common name political, and deals with individuals."

I answer that, A slave is moved by his master, and a subject by his ruler, by command, but otherwise than as irrational and inanimate beings are set in motion by their movers. For irrational and inanimate beings are moved only by others and do not put themselves in motion, since they have no free-will whereby to be masters of their own actions, wherefore the rectitude of their government is not in their power but in the power of their movers. On the other hand, men who are slaves or subjects in any sense, are moved by the commands of others in such a way that they move themselves by their free-will; wherefore some kind of rectitude of government is required in them, so that they may direct themselves in obeying their superiors; and to this belongs that species of prudence which is called political.

Reply to Objection 1: As stated above, regnative is the most perfect species of prudence, wherefore the prudence of subjects, which falls short of regnative prudence, retains the common name of political prudence, even as in logic a convertible term which does not denote the essence of a thing retains the name of "proper."

Reply to Objection 2: A different aspect of the object diversifies the species of a habit, as stated above (Q[47], A[5]). Now the same actions are considered by the king, but under a more general aspect, as by his subjects who obey: since many obey one king in various departments. Hence regnative prudence is compared to this political prudence of which we are speaking, as mastercraft to handicraft.

Reply to Objection 3: Man directs himself by prudence commonly so called, in relation to his own good, but by political prudence, of which we speak, he directs himself in relation to the common good.

Objection 1: It would seem that domestic should not be reckoned a part of prudence. For, according to the Philosopher (Ethic. vi, 5) "prudence is directed to a good life in general": whereas domestic prudence is directed to a particular end, viz. wealth, according to Ethic. i, 1. Therefore a species of prudence is not domestic.

Objection 2: Further, as stated above (Q[47], A[13]) prudence is only in good people. But domestic prudence may be also in wicked people, since many sinners are provident in governing their household. Therefore domestic prudence should not be reckoned a species of prudence.

Objection 3: Further, just as in a kingdom there is a ruler and subject, so also is there in a household. If therefore domestic like political is a species of prudence, there should be a paternal corresponding to regnative prudence. Now there is no such prudence. Therefore neither should domestic prudence be accounted a species of prudence.

On the contrary, The Philosopher states (Ethic. vi, 8) that there are various kinds of prudence in the government of a multitude, "one of which is domestic, another legislative, and another political."

I answer that, Different aspects of an object, in respect of universality and particularity, or of totality and partiality, diversify arts and virtues; and in respect of such diversity one act of virtue is principal as compared with another. Now it is evident that a household is a mean between the individual and the city or kingdom, since just as the individual is part of the household, so is the household part of the city or kingdom. And therefore, just as prudence commonly so called which governs the individual, is distinct from political prudence, so must domestic prudence be distinct from both.

Reply to Objection 1: Riches are compared to domestic prudence, not as its last end, but as its instrument, as stated in Polit. i, 3. On the other hand, the end of political prudence is "a good life in general" as regards the conduct of the household. In Ethic. i, 1 the Philosopher speaks of riches as the end of political prudence, by way of example and in accordance with the opinion of many.

Reply to Objection 2: Some sinners may be provident in certain matters of detail concerning the disposition of their household, but not in regard to "a good life in general" as regards the conduct of the household, for which above all a virtuous life is required.

Reply to Objection 3: The father has in his household an authority like that of a king, as stated in Ethic. viii, 10, but he has not the full power of a king, wherefore paternal government is not reckoned a distinct species of prudence, like regnative prudence.

Objection 1: It would seem that military prudence should not be reckoned a part of prudence. For prudence is distinct from art, according to Ethic. vi, 3. Now military prudence seems to be the art of warfare, according to the Philosopher (Ethic. iii, 8). Therefore military prudence should not be accounted a species of prudence.

Objection 2: Further, just as military business is contained under political affairs, so too are many other matters, such as those of tradesmen, craftsmen, and so forth. But there are no species of prudence corresponding to other affairs in the state. Neither therefore should any be assigned to military business.

Objection 3: Further, the soldiers' bravery counts for a great deal in warfare. Therefore military prudence pertains to fortitude rather than to prudence.

On the contrary, It is written (Prov. 24:6): "War is managed by due ordering, and there shall be safety where there are many counsels." Now it belongs to prudence to take counsel. Therefore there is great need in warfare for that species of prudence which is called "military."

I answer that, Whatever things are done according to art or reason, should be made to conform to those which are in accordance with nature, and are established by the Divine Reason. Now nature has a twofold tendency: first, to govern each thing in itself, secondly, to withstand outward assailants and corruptives: and for this reason she has provided animals not only with the concupiscible faculty, whereby they are moved to that which is conducive to their well-being, but also with the irascible power, whereby the animal withstands an assailant. Therefore in those things also which are in accordance with reason, there should be not only "political" prudence, which disposes in a suitable manner such things as belong to the common good, but also a "military" prudence, whereby hostile attacks are repelled.

Reply to Objection 1: Military prudence may be an art, in so far as it has certain rules for the right use of certain external things, such as arms and horses, but in so far as it is directed to the common good, it belongs rather to prudence.

Reply to Objection 2: Other matters in the state are directed to the profit of individuals, whereas the business of soldiering is directed to the service belongs to fortitude, but the direction, protection of the entire common good.

Reply to Objection 3: The execution of military service belongs to fortitude, but the direction, especially in so far as it concerns the commander-in-chief, belongs to prudence.

In due sequence, we must consider the virtues that are connected with prudence, and which are its quasi-potential parts. Under this head there are four points of inquiry:

(1) Whether {euboulia}, is a virtue?

(2) Whether it is a special virtue, distinct from prudence?

(3) Whether {synesis} is a special virtue?

(4) Whether {gnome} is a special virtue?

Objection 1: It would seem that {euboulia} (deliberating well) is not a virtue. For, according to Augustine (De Lib. Arb. ii, 18,19) "no man makes evil use of virtue." Now some make evil use of {euboulia} (deliberating well) or good counsel, either through devising crafty counsels in order to achieve evil ends, or through committing sin in order that they may achieve good ends, as those who rob that they may give alms. Therefore {euboulia} (deliberating well) is not a virtue.

Objection 2: Further, virtue is a perfection, according to Phys. vii. But {euboulia} (deliberating well) is concerned with counsel, which implies doubt and research, and these are marks of imperfection. Therefore {euboulia} (deliberating well) is not a virtue.

Objection 3: Further, virtues are connected with one another, as stated above (FS, Q[65]). Now {euboulia} (deliberating well) is not connected with the other virtues, since many sinners take good-counsel, and many godly men are slow in taking counsel. Therefore {euboulia} (deliberating well) is not a virtue.

On the contrary, According to the Philosopher (Ethic. vi, 9) {euboulia} (deliberating well) "is a right counselling." Now the perfection of virtue consists in right reason. Therefore {euboulia} (deliberating well) is a virtue.

I answer that, As stated above (Q[47], A[4]) the nature of a human virtue consists in making a human act good. Now among the acts of man, it is proper to him to take counsel, since this denotes a research of the reason about the actions he has to perform and whereof human life consists, for the speculative life is above man, as stated in Ethic. x. But {euboulia} (deliberating well) signifies goodness of counsel, for it is derived from the {eu}, good, and {boule}, counsel, being "a good counsel" or rather "a disposition to take good counsel." Hence it is evident that {euboulia} (deliberating well) is a human virtue.

Reply to Objection 1: There is no good counsel either in deliberating for an evil end, or in discovering evil means for attaining a good end, even as in speculative matters, there is no good reasoning either in coming to a false conclusion, or in coming to a true conclusion from false premisses through employing an unsuitable middle term. Hence both the aforesaid processes are contrary to {euboulia} (deliberating well), as the Philosopher declares (Ethic. vi, 9).

Reply to Objection 2: Although virtue is essentially a perfection, it does not follow that whatever is the matter of a virtue implies perfection. For man needs to be perfected by virtues in all his parts, and this not only as regards the acts of reason, of which counsel is one, but also as regards the passions of the sensitive appetite, which are still more imperfect.

It may also be replied that human virtue is a perfection according to the mode of man, who is unable by simple insight to comprehend with certainty the truth of things, especially in matters of action which are contingent.

Reply to Objection 3: In no sinner as such is {euboulia} (deliberating well) to be found: since all sin is contrary to taking good counsel. For good counsel requires not only the discovery or devising of fit means for the end, but also other circumstances. Such are suitable time, so that one be neither too slow nor too quick in taking counsel, and the mode of taking counsel, so that one be firm in the counsel taken, and other like due circumstances, which sinners fail to observe when they sin. On the other hand, every virtuous man takes good counsel in those things which are directed to the end of virtue, although perhaps he does not take good counsel in other particular matters, for instance in matters of trade, or warfare, or the like.

Objection 1: It would seem that {euboulia} (deliberating well) is not a distinct virtue from prudence. For, according to the Philosopher (Ethic. vi, 5), the "prudent man is, seemingly, one who takes good counsel." Now this belongs to {euboulia} (deliberating well) as stated above. Therefore {euboulia} (deliberating well) is not distinct from prudence.

Objection 2: Further, human acts to which human virtues are directed, are specified chiefly by their end, as stated above (FS, Q[1], A[3]; FS, Q[18], AA,6). Now {euboulia} (deliberating well) and prudence are directed to the same end, as stated in Ethic. vi, 9, not indeed to some particular end, but to the common end of all life. Therefore {euboulia} (deliberating well) is not a distinct virtue from prudence.

Objection 3: Further, in speculative sciences, research and decision belong to the same science. Therefore in like manner these belong to the same virtue in practical matters. Now research belongs to {euboulia} (deliberating well), while decision belongs to prudence. There {euboulia} (deliberating well) is not a distinct virtue from prudence.

On the contrary, Prudence is preceptive, according to Ethic. vi, 10. But this does not apply to {euboulia} (deliberating well). Therefore {euboulia} (deliberating well) is a distinct virtue from prudence.

I answer that, As stated above(A[1]), virtue is properly directed to an act which it renders good; and consequently virtues must differ according to different acts, especially when there is a different kind of goodness in the acts. For, if various acts contained the same kind of goodness, they would belong to the same virtue: thus the goodness of love, desire and joy depends on the same, wherefore all these belong to the same virtue of charity.

Now acts of the reason that are ordained to action are diverse, nor have they the same kind of goodness: since it is owing to different causes that a man acquires good counsel, good judgment, or good command, inasmuch as these are sometimes separated from one another. Consequently {euboulia} (deliberating well) which makes man take good counsel must needs be a distinct virtue from prudence, which makes man command well. And since counsel is directed to command as to that which is principal, so {euboulia} (deliberating well) is directed to prudence as to a principal virtue, without which it would be no virtue at all, even as neither are the moral virtues without prudence, nor the other virtues without charity.

Reply to Objection 1: It belongs to prudence to take good counsel by commanding it, to {euboulia} (deliberating well) by eliciting it.

Reply to Objection 2: Different acts are directed in different degrees to the one end which is "a good life in general" [*Ethic. vi, 5]: for counsel comes first, judgment follows, and command comes last. The last named has an immediate relation to the last end: whereas the other two acts are related thereto remotely. Nevertheless these have certain proximate ends of their own, the end of counsel being the discovery of what has to be done, and the end of judgment, certainty. Hence this proves not that {euboulia} (deliberating well) is not a distinct virtue from prudence, but that it is subordinate thereto, as a secondary to a principal virtue.

Reply to Objection 3: Even in speculative matters the rational science of dialectics, which is directed to research and discovery, is distinct from demonstrative science, which decides the truth.

Objection 1: It would seem that {synesis} is not a virtue. Virtues are not in us by nature, according to Ethic. ii, 1. But {synesis} (judging well according to common law) is natural to some, as the Philosopher states (Ethic. vi, 11). Therefore {synesis} (judging well according to common law) is not a virtue.

Objection 2: Further, as stated in the same book (10), {synesis} (judging well according to common law) is nothing but "a faculty of judging." But judgment without command can be even in the wicked. Since then virtue is only in the good, it seems that {synesis} (judging well according to common law) is not a virtue.

Objection 3: Further, there is never a defective command, unless there be a defective judgment, at least in a particular matter of action; for it is in this that every wicked man errs. If therefore {synesis} (judging well according to common law) be reckoned a virtue directed to good judgment, it seems that there is no need for any other virtue directed to good command: and consequently prudence would be superfluous, which is not reasonable. Therefore {synesis} (judging well according to common law) is not a virtue.

On the contrary, Judgment is more perfect than counsel. But {euboulia}, or good counsel, is a virtue. Much more, therefore, is {synesis} (judging well according to common law) a virtue, as being good judgment.

I answer that, {synesis} (judging well according to common law) signifies a right judgment, not indeed about speculative matters, but about particular practical matters, about which also is prudence. Hence in Greek some, in respect of {synesis} (judging well according to common law) are said to be {synetoi}, i.e. "persons of sense," or {eusynetoi}, i.e. "men of good sense," just as on the other hand, those who lack this virtue are called {asynetoi}, i.e. "senseless."

Now, different acts which cannot be ascribed to the same cause, must correspond to different virtues. And it is evident that goodness of counsel and goodness of judgment are not reducible to the same cause, for many can take good counsel, without having good sense so as to judge well. Even so, in speculative matters some are good at research, through their reason being quick at arguing from one thing to another (which seems to be due to a disposition of their power of imagination, which has a facility in forming phantasms), and yet such persons sometimes lack good judgment (and this is due to a defect in the intellect arising chiefly from a defective disposition of the common sense which fails to judge aright). Hence there is need, besides {euboulia} (deliberating well), for another virtue, which judges well, and this is called {synesis} (judging well according to common law).

Reply to Objection 1: Right judgment consists in the cognitive power apprehending a thing just as it is in reality, and this is due to the right disposition of the apprehensive power. Thus if a mirror be well disposed the forms of bodies are reflected in it just as they are, whereas if it be ill disposed, the images therein appear distorted and misshapen. Now that the cognitive power be well disposed to receive things just as they are in reality, is radically due to nature, but, as to its consummation, is due to practice or to a gift of grace, and this in two ways. First directly, on the part of the cognitive power itself, for instance, because it is imbued, not with distorted, but with true and correct ideas: this belongs to {synesis} (judging well according to common law) which in this respect is a special virtue. Secondly indirectly, through the good disposition of the appetitive power, the result being that one judges well of the objects of appetite: and thus a good judgment of virtue results from the habits of moral virtue; but this judgment is about the ends, whereas {synesis} (judging well according to common law) is rather about the means.

Reply to Objection 2: In wicked men there may be right judgment of a universal principle, but their judgment is always corrupt in the particular matter of action, as stated above (Q[47], A[13]).

Reply to Objection 3: Sometimes after judging aright we delay to execute or execute negligently or inordinately. Hence after the virtue which judges aright there is a further need of a final and principal virtue, which commands aright, and this is prudence.

Objection 1: It would seem that {gnome} (judging well according to general law) is not a special virtue distinct from {synesis} (judging well according to common law). For a man is said, in respect of {synesis} (judging well according to common law), to have good judgment. Now no man can be said to have good judgment, unless he judge aright in all things. Therefore {synesis} (judging well according to common law) extends to all matters of judgment, and consequently there is no other virtue of good judgment called {gnome} (judging well according to general law).

Objection 2: Further, judgment is midway between counsel and precept. Now there is only one virtue of good counsel, viz. {euboulia} (deliberating well) and only one virtue of good command, viz. prudence. Therefore there is only one virtue of good judgment, viz. {synesis} (judging well according to common law).

Objection 3: Further, rare occurrences wherein there is need to depart from the common law, seem for the most part to happen by chance, and with such things reason is not concerned, as stated in Phys. ii, 5. Now all the intellectual virtues depend on right reason. Therefore there is no intellectual virtue about such matters.

On the contrary, The Philosopher concludes (Ethic. vi, 11) that {gnome} (judging well according to general law) is a special virtue.

I answer that cognitive habits differ according to higher and lower principles: thus in speculative matters wisdom considers higher principles than science does, and consequently is distinguished from it; and so must it be also in practical matters. Now it is evident that what is beside the order of a lower principle or cause, is sometimes reducible to the order of a higher principle; thus monstrous births of animals are beside the order of the active seminal force, and yet they come under the order of a higher principle, namely, of a heavenly body, or higher still, of Divine Providence. Hence by considering the active seminal force one could not pronounce a sure judgment on such monstrosities, and yet this is possible if we consider Divine Providence.

Now it happens sometimes that something has to be done which is not covered by the common rules of actions, for instance in the case of the enemy of one's country, when it would be wrong to give him back his deposit, or in other similar cases. Hence it is necessary to judge of such matters according to higher principles than the common laws, according to which {synesis} (judging according to common law) judges: and corresponding to such higher principles it is necessary to have a higher virtue of judgment, which is called {gnome} (judging according to general law), and which denotes a certain discrimination in judgment.

Reply to Objection 1: {Synesis} (judging well according to common law) judges rightly about all actions that are covered by the common rules: but certain things have to be judged beside these common rules, as stated above.

Reply to Objection 2: Judgment about a thing should be formed from the proper principles thereof, whereas research is made by employing also common principles. Wherefore also in speculative matters, dialectics which aims at research proceeds from common principles; while demonstration which tends to judgment, proceeds from proper principles. Hence {euboulia} (deliberating well) to which the research of counsel belongs is one for all, but not so {synesis} (judging well according to common law) whose act is judicial. Command considers in all matters the one aspect of good, wherefore prudence also is only one.

Reply to Objection 3: It belongs to Divine Providence alone to consider all things that may happen beside the common course. On the other hand, among men, he who is most discerning can judge a greater number of such things by his reason: this belongs to {gnome} (judging well according to general law), which denotes a certain discrimination in judgment.
