Summa Theologica, Saint Thomas Aquinas [best ebook for manga TXT] 📗

are instances of a certain natural prudence in dumb animals, according to the Philosopher (De Hist. Anim. viii, 1). Therefore prudence is natural.

On the contrary, The Philosopher says (Ethic. ii, 1) that "intellectual virtue is both originated and fostered by teaching; it therefore demands experience and time." Now prudence is an intellectual virtue, as stated above (A. 4). Therefore prudence is in us, not by nature, but by teaching and experience.

I answer that, As shown above (A. 3), prudence includes knowledge both of universals, and of the singular matters of action to which prudence applies the universal principles. Accordingly, as regards the knowledge of universals, the same is to be said of prudence as of speculative science, because the primary universal principles of either are known naturally, as shown above (A. 6): except that the common principles of prudence are more connatural to man; for as the Philosopher remarks (Ethic. x, 7) "the life which is according to the speculative reason is better than that which is according to man": whereas the secondary universal principles, whether of the speculative or of the practical reason, are not inherited from nature, but are acquired by discovery through experience, or through teaching.

On the other hand, as regards the knowledge of particulars which are the matter of action, we must make a further distinction, because this matter of action is either an end or the means to an end. Now the right ends of human life are fixed; wherefore there can be a natural inclination in respect of these ends; thus it has been stated above (I-II, Q. 51, A. 1; Q. 63, A. 1) that some, from a natural inclination, have certain virtues whereby they are inclined to right ends; and consequently they also have naturally a right judgment about such like ends.

But the means to the end, in human concerns, far from being fixed, are of manifold variety according to the variety of persons and affairs. Wherefore since the inclination of nature is ever to something fixed, the knowledge of those means cannot be in man naturally, although, by reason of his natural disposition, one man has a greater aptitude than another in discerning them, just as it happens with regard to the conclusions of speculative sciences. Since then prudence is not about the ends, but about the means, as stated above (A. 6; I-II, Q. 57, A. 5), it follows that prudence is not from nature.

Reply Obj. 1: The Philosopher is speaking there of things relating to prudence, in so far as they are directed to ends. Wherefore he had said before (Ethic. vi, 5, 11) that "they are the principles of the ou heneka" [*Literally, 'for the sake of which' (are the means)], namely, the end; and so he does not mention euboulia among them, because it takes counsel about the means.

Reply Obj. 2: Prudence is rather in the old, not only because their natural disposition calms the movement of the sensitive passions, but also because of their long experience.

Reply Obj. 3: Even in dumb animals there are fixed ways of obtaining an end, wherefore we observe that all the animals of a same species act in like manner. But this is impossible in man, on account of his reason, which takes cognizance of universals, and consequently extends to an infinity of singulars. _______________________

SIXTEENTH ARTICLE [II-II, Q. 47, Art. 16]

Whether Prudence Can Be Lost Through Forgetfulness?

Objection 1: It would seem that prudence can be lost through forgetfulness. For since science is about necessary things, it is more certain than prudence which is about contingent matters of action. But science is lost by forgetfulness. Much more therefore is prudence.

Obj. 2: Further, as the Philosopher says (Ethic. ii, 3) "the same things, but by a contrary process, engender and corrupt virtue." Now the engendering of prudence requires experience which is made up "of many memories," as he states at the beginning of his Metaphysics (i, 1). Therefore since forgetfulness is contrary to memory, it seems that prudence can be lost through forgetfulness.

Obj. 3: Further, there is no prudence without knowledge of universals. But knowledge of universals can be lost through forgetfulness. Therefore prudence can also.

On the contrary, The Philosopher says (Ethic. vi, 5) that "forgetfulness is possible to art but not to prudence."

I answer that, Forgetfulness regards knowledge only, wherefore one can forget art and science, so as to lose them altogether, because they belong to the reason. But prudence consists not in knowledge alone, but also in an act of the appetite, because as stated above (A. 8), its principal act is one of command, whereby a man applies the knowledge he has, to the purpose of appetition and operation. Hence prudence is not taken away directly by forgetfulness, but rather is corrupted by the passions. For the Philosopher says (Ethic. vi, 5) that "pleasure and sorrow pervert the estimate of prudence": wherefore it is written (Dan. 13:56): "Beauty hath deceived thee, and lust hath subverted thy heart," and (Ex. 23:8): "Neither shalt thou take bribes which blind even the prudent [Douay: 'wise']."

Nevertheless forgetfulness may hinder prudence, in so far as the latter's command depends on knowledge which may be forgotten.

Reply Obj. 1: Science is in the reason only: hence the comparison fails, as stated above [*Cf. I-II, Q. 53, A. 1].

Reply Obj. 2: The experience required by prudence results not from memory alone, but also from the practice of commanding aright.

Reply Obj. 3: Prudence consists chiefly, not in the knowledge of universals, but in applying them to action, as stated above (A. 3). Wherefore forgetting the knowledge of universals does not destroy the principal part of prudence, but hinders it somewhat, as stated above. _______________________

QUESTION 48

OF THE PARTS OF PRUDENCE
(In One Article)

We must now consider the parts of prudence, under which head there are four points of inquiry:

(1) Which are the parts of prudence?

(2) Of its integral parts;

(3) Of its subjective parts;

(4) Of its potential parts. _______________________

ARTICLE [II-II, Q. 48, Art.]

Whether Three Parts of Prudence Are Fittingly Assigned?

Objection 1: It would seem that the parts of prudence are assigned unfittingly. Tully (De Invent. Rhet. ii, 53) assigns three parts of prudence, namely, "memory," "understanding" and "foresight." Macrobius (In Somn. Scip. i) following the opinion of Plotinus ascribes to prudence six parts, namely, "reasoning," "understanding," "circumspection," "foresight," "docility" and "caution." Aristotle says (Ethic. vi, 9, 10, 11) that "good counsel," "synesis" and "gnome" belong to prudence. Again under the head of prudence he mentions "conjecture," "shrewdness," "sense" and "understanding." And another Greek philosopher [*Andronicus; Cf. Q. 80, Obj. 4] says that ten things are connected with prudence, namely, "good counsel," "shrewdness," "foresight," "regnative [*Regnativa]," "military," "political" and "domestic prudence," "dialectics," "rhetoric" and "physics." Therefore it seems that one or the other enumeration is either excessive or deficient.

Obj. 2: Further, prudence is specifically distinct from science. But politics, economics, logic, rhetoric, physics are sciences. Therefore they are not parts of prudence.

Obj. 3: Further, the parts do not exceed the whole. Now the intellective memory or intelligence, reason, sense and docility, belong not only to prudence but also to all the cognitive habits. Therefore they should not be set down as parts of prudence.

Obj. 4: Further, just as counselling, judging and commanding are acts of the practical reason, so also is using, as stated above (I-II, Q. 16, A. 1). Therefore, just as "eubulia" which refers to counsel, is connected with prudence, and "synesis" and "gnome" which refer to judgment, so also ought something to have been assigned corresponding to use.

Obj. 5: Further, solicitude pertains to prudence, as stated above (Q. 47, A. 9). Therefore solicitude also should have been mentioned among the parts of prudence.

I answer that, Parts are of three kinds, namely, integral, as wall, roof, and foundations are parts of a house; subjective, as ox and lion are parts of animal; and potential, as the nutritive and sensitive powers are parts of the soul. Accordingly, parts can be assigned to a virtue in three ways. First, in likeness to integral parts, so that the things which need to concur for the perfect act of a virtue, are called the parts of that virtue. In this way, out of all the things mentioned above, eight may be taken as parts of prudence, namely, the six assigned by Macrobius; with the addition of a seventh, viz. memory mentioned by Tully; and eustochia or shrewdness mentioned by Aristotle. For the sense of prudence is also called understanding: wherefore the Philosopher says (Ethic. vi, 11): "Of such things one needs to have the sense, and this is understanding." Of these eight, five belong to prudence as a cognitive virtue, namely, _memory, reasoning, understanding, docility and shrewdness: while the three others belong thereto, as commanding and applying knowledge to action, namely, foresight, circumspection and caution. The reason of their difference is seen from the fact that three things may be observed in reference to knowledge. In the first place, knowledge itself, which, if it be of the past, is called memory, if of the present, whether contingent or necessary, is called understanding or intelligence. Secondly, the acquiring of knowledge, which is caused either by teaching, to which pertains docility, or by discovery, and to this belongs to eustochia, i.e. "a happy conjecture," of which shrewdness is a part, which is a "quick conjecture of the middle term," as stated in Poster. i, 9. Thirdly, the use of knowledge, in as much as we proceed from things known to knowledge or judgment of other things, and this belongs to reasoning. And the reason, in order to command aright, requires to have three conditions. First, to order that which is befitting the end, and this belongs to foresight; secondly, to attend to the circumstances of the matter in hand, and this belongs to circumspection; thirdly, to avoid obstacles, and this belongs to caution.

The subjective parts of a virtue are its various species. In this way the parts of prudence, if we take them properly, are the prudence whereby a man rules himself, and the prudence whereby a man governs a multitude, which differ specifically as stated above (Q. 47, A. 11). Again, the prudence whereby a multitude is governed, is divided into various species according to the various kinds of multitude. There is the multitude which is united together for some particular purpose; thus an army is gathered together to fight, and the prudence that governs this is called military. There is also the multitude that is united together for the whole of life; such is the multitude of a home or family, and this is ruled by domestic prudence: and such again is the multitude of a city or kingdom, the ruling principle of which is regnative prudence in the ruler, and political prudence, simply so called, in the subjects.

If, however, prudence be taken in a wide sense, as including also speculative knowledge, as stated above (Q. 47, A. 2, ad 2) then its parts include dialectics, rhetoric and physics, according to three methods of prudence in the sciences. The first of these is the attaining of science by demonstration, which belongs to physics (if physics be understood to comprise all demonstrative sciences). The second method is to arrive at an opinion through probable premises, and this belongs to dialectics. The third method is to employ conjectures in order to induce a certain suspicion, or to persuade somewhat, and this belongs to rhetoric. It may be said, however, that these three belong also to prudence properly so called, since it argues sometimes from necessary premises, sometimes from probabilities, and sometimes from conjectures.

The potential parts of a virtue are the virtues connected with it, which are directed to certain secondary acts or matters, not having, as it were, the whole power of the principal virtue. In this way the parts of prudence are good counsel, which concerns counsel, synesis, which concerns judgment in matters of ordinary occurrence, and gnome, which concerns judgment in matters of exception to the law: while prudence is about the chief act, viz. that of commanding.

Reply Obj. 1: The various enumerations differ, either because different kinds of parts are assigned, or because that which is mentioned in one enumeration includes several mentioned in another enumeration. Thus Tully includes "caution" and "circumspection" under "foresight," and "reasoning," "docility" and "shrewdness" under "understanding."

Reply Obj. 2: Here domestic and civic prudence are not to be taken as sciences, but as kinds of prudence. As to the other three, the reply may be gathered from what has been said.

Reply Obj. 3: All these things are reckoned parts of prudence, not by taking them altogether, but in so far as they are connected with things pertaining to prudence.

Reply Obj. 4: Right command and right use always go together, because the reason's command is followed by obedience on the part of the lower powers, which pertain to use.
