OF EACH QUASI-INTEGRAL PART OF PRUDENCE
(In Eight Articles)

We must now consider each quasi-integral part of prudence, and under this head there are eight points of inquiry:

(1) Memory;

(2) Understanding or Intelligence;

(3) Docility;

(4) Shrewdness;

(5) Reason;

(6) Foresight;

(7) Circumspection;

(8) Caution. _______________________

FIRST ARTICLE [II-II, Q. 49, Art. 1]

Whether Memory Is a Part of Prudence?

Objection 1: It would seem that memory is not a part of prudence. For memory, as the Philosopher proves (De Memor. et Remin. i), is in the sensitive part of the soul: whereas prudence is in the rational part (Ethic. vi, 5). Therefore memory is not a part of prudence.

Obj. 2: Further, prudence is acquired and perfected by experience, whereas memory is in us from nature. Therefore memory is not a part of prudence.

Obj. 3: Further, memory regards the past, whereas prudence regards future matters of action, about which counsel is concerned, as stated in Ethic. vi, 2, 7. Therefore memory is not a part of prudence.

On the contrary, Tully (De Invent. Rhet. ii, 53) places memory among the parts of prudence.

I answer that, Prudence regards contingent matters of action, as stated above (Q. 47, A. 5). Now in such like matters a man can be directed, not by those things that are simply and necessarily true, but by those which occur in the majority of cases: because principles must be proportionate to their conclusions, and "like must be concluded from like" (Ethic. vi [*Anal. Post. i. 32]). But we need experience to discover what is true in the majority of cases: wherefore the Philosopher says (Ethic. ii, 1) that "intellectual virtue is engendered and fostered by experience and time." Now experience is the result of many memories as stated in Metaph. i, 1, and therefore prudence requires the memory of many things. Hence memory is fittingly accounted a part of prudence.

Reply Obj. 1: As stated above (Q. 47, AA. 3, 6), prudence applies universal knowledge to particulars which are objects of sense: hence many things belonging to the sensitive faculties are requisite for prudence, and memory is one of them.

Reply Obj. 2: Just as aptitude for prudence is in our nature, while its perfection comes through practice or grace, so too, as Tully says in his Rhetoric [*Ad Herenn. de Arte Rhet. iii, 16, 24], memory not only arises from nature, but is also aided by art and diligence.

There are four things whereby a man perfects his memory. First, when a man wishes to remember a thing, he should take some suitable yet somewhat unwonted illustration of it, since the unwonted strikes us more, and so makes a greater and stronger impression on the mind; the mind; and this explains why we remember better what we saw when we were children. Now the reason for the necessity of finding these illustrations or images, is that simple and spiritual impressions easily slip from the mind, unless they be tied as it were to some corporeal image, because human knowledge has a greater hold on sensible objects. For this reason memory is assigned to the sensitive part of the soul. Secondly, whatever a man wishes to retain in his memory he must carefully consider and set in order, so that he may pass easily from one memory to another. Hence the Philosopher says (De Memor. et Remin. ii): "Sometimes a place brings memories back to us: the reason being that we pass quickly from the one to the other." Thirdly, we must be anxious and earnest about the things we wish to remember, because the more a thing is impressed on the mind, the less it is liable to slip out of it. Wherefore Tully says in his Rhetoric [*Ad Herenn. de Arte Rhet. iii.] that "anxiety preserves the figures of images entire." Fourthly, we should often reflect on the things we wish to remember. Hence the Philosopher says (De Memoria i) that "reflection preserves memories," because as he remarks (De Memoria ii) "custom is a second nature": wherefore when we reflect on a thing frequently, we quickly call it to mind, through passing from one thing to another by a kind of natural order.

Reply Obj. 3: It behooves us to argue, as it were, about the future from the past; wherefore memory of the past is necessary in order to take good counsel for the future. _______________________

SECOND ARTICLE [II-II, Q. 49, Art. 2]

Whether Understanding* Is a Part of Prudence?
[*Otherwise intuition; Aristotle's word is nous]

Objection 1: It would seem that understanding is not a part of prudence. When two things are members of a division, one is not part of the other. But intellectual virtue is divided into understanding and prudence, according to Ethic. vi, 3. Therefore understanding should not be reckoned a part of prudence.

Obj. 2: Further, understanding is numbered among the gifts of the Holy Ghost, and corresponds to faith, as stated above (Q. 8, AA. 1, 8). But prudence is a virtue other than faith, as is clear from what has been said above (Q. 4, A. 8; I-II, Q. 62, A. 2). Therefore understanding does not pertain to prudence.

Obj. 3: Further, prudence is about singular matters of action (Ethic. vi, 7): whereas understanding takes cognizance of universal and immaterial objects (De Anima iii, 4). Therefore understanding is not a part of prudence.

On the contrary, Tully [*De Invent. Rhet. ii, 53] accounts "intelligence" a part of prudence, and Macrobius [*In Somn. Scip. i, 8] mentions "understanding," which comes to the same.

I answer that, Understanding denotes here, not the intellectual power, but the right estimate about some final principle, which is taken as self-evident: thus we are said to understand the first principles of demonstrations. Now every deduction of reason proceeds from certain statements which are taken as primary: wherefore every process of reasoning must needs proceed from some understanding. Therefore since prudence is right reason applied to action, the whole process of prudence must needs have its source in understanding. Hence it is that understanding is reckoned a part of prudence.

Reply Obj. 1: The reasoning of prudence terminates, as in a conclusion, in the particular matter of action, to which, as stated above (Q. 47, AA. 3, 6), it applies the knowledge of some universal principle. Now a singular conclusion is argued from a universal and a singular proposition. Wherefore the reasoning of prudence must proceed from a twofold understanding. The one is cognizant of universals, and this belongs to the understanding which is an intellectual virtue, whereby we know naturally not only speculative principles, but also practical universal principles, such as "One should do evil to no man," as shown above (Q. 47, A. 6). The other understanding, as stated in Ethic. vi, 11, is cognizant of an extreme, i.e. of some primary singular and contingent practical matter, viz. the minor premiss, which must needs be singular in the syllogism of prudence, as stated above (Q. 47, AA. 3, 6). Now this primary singular is some singular end, as stated in the same place. Wherefore the understanding which is a part of prudence is a right estimate of some particular end.

Reply Obj. 2: The understanding which is a gift of the Holy Ghost, is a quick insight into divine things, as shown above (Q. 8, AA. 1, 2). It is in another sense that it is accounted a part of prudence, as stated above.

Reply Obj. 3: The right estimate about a particular end is called both "understanding," in so far as its object is a principle, and "sense," in so far as its object is a particular. This is what the Philosopher means when he says (Ethic. v, 11): "Of such things we need to have the sense, and this is understanding." But this is to be understood as referring, not to the particular sense whereby we know proper sensibles, but to the interior sense, whereby we judge of a particular. _______________________

THIRD ARTICLE [II-II, Q. 49, Art. 3]

Whether Docility Should Be Accounted a Part of Prudence?

Objection 1: It would seem that docility should not be accounted a part of prudence. For that which is a necessary condition of every intellectual virtue, should not be appropriated to one of them. But docility is requisite for every intellectual virtue. Therefore it should not be accounted a part of prudence.

Obj. 2: Further, that which pertains to a human virtue is in our power, since it is for things that are in our power that we are praised or blamed. Now it is not in our power to be docile, for this is befitting to some through their natural disposition. Therefore it is not a part of prudence.

Obj. 3: Further, docility is in the disciple: whereas prudence, since it makes precepts, seems rather to belong to teachers, who are also called "preceptors." Therefore docility is not a part of prudence.

On the contrary, Macrobius [*In Somn. Scip. i, 8] following the opinion of Plotinus places docility among the parts of prudence.

I answer that, As stated above (A. 2, ad 1; Q. 47, A. 3) prudence is concerned with particular matters of action, and since such matters are of infinite variety, no one man can consider them all sufficiently; nor can this be done quickly, for it requires length of time. Hence in matters of prudence man stands in very great need of being taught by others, especially by old folk who have acquired a sane understanding of the ends in practical matters. Wherefore the Philosopher says (Ethic. vi, 11): "It is right to pay no less attention to the undemonstrated assertions and opinions of such persons as are experienced, older than we are, and prudent, than to their demonstrations, for their experience gives them an insight into principles." Thus it is written (Prov. 3:5): "Lean not on thy own prudence," and (Ecclus. 6:35): "Stand in the multitude of the ancients" (i.e. the old men), "that are wise, and join thyself from thy heart to their wisdom." Now it is a mark of docility to be ready to be taught: and consequently docility is fittingly reckoned a part of prudence.

Reply Obj. 1: Although docility is useful for every intellectual virtue, yet it belongs to prudence chiefly, for the reason given above.

Reply Obj. 2: Man has a natural aptitude for docility even as for other things connected with prudence. Yet his own efforts count for much towards the attainment of perfect docility: and he must carefully, frequently and reverently apply his mind to the teachings of the learned, neither neglecting them through laziness, nor despising them through pride.

Reply Obj. 3: By prudence man makes precepts not only for others, but also for himself, as stated above (Q. 47, A. 12, ad 3). Hence as stated (Ethic. vi, 11), even in subjects, there is place for prudence; to which docility pertains. And yet even the learned should be docile in some respects, since no man is altogether self-sufficient in matters of prudence, as stated above. _______________________

FOURTH ARTICLE [II-II, Q. 49, Art. 4]

Whether Shrewdness Is Part of Prudence?

Objection 1: It would seem that shrewdness is not a part of prudence. For shrewdness consists in easily finding the middle term for demonstrations, as stated in Poster. i, 34. Now the reasoning of prudence is not a demonstration since it deals with contingencies. Therefore shrewdness does not pertain to prudence.

Obj. 2: Further, good counsel pertains to prudence according to Ethic. vi, 5, 7, 9. Now there is no place in good counsel for shrewdness [*Ethic. vi, 9; Poster. i, 34] which is a kind of eustochia, i.e. "a happy conjecture": for the latter is "unreasoning and rapid," whereas counsel needs to be slow, as stated in Ethic. vi, 9. Therefore shrewdness should not be accounted a part of prudence.

Obj. 3: Further, shrewdness as stated above (Q. 48) is a "happy conjecture." Now it belongs to rhetoricians to make use of conjectures. Therefore shrewdness belongs to rhetoric rather than to prudence.

On the contrary, Isidore says (Etym. x): "A solicitous man is one who is shrewd and alert (solers citus)." But solicitude belongs to prudence, as stated above (Q. 47, A. 9). Therefore shrewdness does also.

I answer that, Prudence consists in a right estimate about matters of action. Now a right estimate or opinion is acquired in two ways, both in practical and in speculative matters, first by discovering it oneself, secondly by learning it from others. Now just as docility consists in a man being well disposed to acquire a right opinion from another man, so shrewdness is an apt disposition to acquire a right estimate by oneself, yet so that shrewdness be taken for eustochia, of which it is a part. For eustochia is a happy conjecture about any matter, while shrewdness is "an easy and rapid conjecture in finding the middle
