| Aquin.: SMT SS Q[48] Out. Para. 1/1 - OF THE PARTS OF PRUDENCE (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.

 Whether three parts of prudence are fittingly assigned?
 
 Aquin.: SMT SS Q[48] A[1] Obj. 1 Para. 1/1
 
 OBJ 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.
 
 Aquin.: SMT SS Q[48] A[1] Obj. 3 Para. 1/1
 
 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.
 
 Aquin.: SMT SS Q[48] A[1] Obj. 4 Para. 1/1
 
 OBJ 4: Further, just as counselling, judging and commanding are acts of
 the practical reason, so also is using, as stated above (FS, 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.
 
 Aquin.: SMT SS Q[48] A[1] Obj. 5 Para. 1/1
 
 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.
 
 Aquin.: SMT SS Q[48] A[1] Body Para. 1/4
 
 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."
 
 Aquin.: SMT SS Q[48] A[1] R.O. 2 Para. 1/1
 
 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.
 
 Aquin.: SMT SS Q[48] A[1] R.O. 3 Para. 1/1
 
 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.
 
 Aquin.: SMT SS Q[48] A[1] R.O. 4 Para. 1/1
 
 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.
 
 Aquin.: SMT SS Q[48] A[1] R.O. 5 Para. 1/1
 
 Reply OBJ 5: Solicitude is included under foresight.
