Summa Theologica by Saint Thomas Aquinas (whitelam books .TXT) 📕

man's sense is plunged into earthly things chiefly by lust, which is about the greatest of pleasures; and these absorb the mind more than any others. Therefore the folly which is a sin, arises chiefly from lust.

Reply Obj. 1: It is part of folly that a man should have a distaste for God and His gifts. Hence Gregory mentions two daughters of lust, pertaining to folly, namely, "hatred of God" and "despair of the life to come"; thus he divides folly into two parts as it were.

Reply Obj. 2: These words of the Apostle are to be understood, not causally but essentially, because, to wit, worldly wisdom itself is folly with God. Hence it does not follow that whatever belongs to worldly wisdom, is a cause of this folly.

Reply Obj. 3: Anger by reason of its keenness, as stated above (I-II, Q. 48, AA. 2, 3, 4), produces a great change in the nature of the body, wherefore it conduces very much to the folly which results from a bodily impediment. On the other hand the folly which is caused by a spiritual impediment, viz. by the mind being plunged into earthly things, arises chiefly from lust, as stated above. _______________________

TREATISE ON THE CARDINAL VIRTUES (QQ. 47-170) _______________________

QUESTION 47

OF PRUDENCE, CONSIDERED IN ITSELF
(In Sixteen Articles)

After treating of the theological virtues, we must in due sequence consider the cardinal virtues. In the first place we shall consider prudence in itself; secondly, its parts; thirdly, the corresponding gift; fourthly, the contrary vices; fifthly, the precepts concerning prudence.

Under the first head there are sixteen points of inquiry:

(1) Whether prudence is in the will or in the reason?

(2) If in the reason, whether it is only in the practical, or also in the speculative reason?

(3) Whether it takes cognizance of singulars?

(4) Whether it is virtue?

(5) Whether it is a special virtue?

(6) Whether it appoints the end to the moral virtues?

(7) Whether it fixes the mean in the moral virtues?

(8) Whether its proper act is command?

(9) Whether solicitude or watchfulness belongs to prudence?

(10) Whether prudence extends to the governing of many?

(11) Whether the prudence which regards private good is the same in species as that which regards the common good?

(12) Whether prudence is in subjects, or only in their rulers?

(13) Whether prudence is in the wicked?

(14) Whether prudence is in all good men?

(15) Whether prudence is in us naturally?

(16) Whether prudence is lost by forgetfulness? _______________________

FIRST ARTICLE [II-II, Q. 47, Art. 1]

Whether Prudence Is in the Cognitive or in the Appetitive Faculty?

Objection 1: It would seem that prudence is not in the cognitive but in the appetitive faculty. For Augustine says (De Morib. Eccl. xv): "Prudence is love choosing wisely between the things that help and those that hinder." Now love is not in the cognitive, but in the appetitive faculty. Therefore prudence is in the appetitive faculty.

Obj. 2: Further, as appears from the foregoing definition it belongs to prudence "to choose wisely." But choice is an act of the appetitive faculty, as stated above (I-II, Q. 13, A. 1). Therefore prudence is not in the cognitive but in the appetitive faculty.

Obj. 3: Further, the Philosopher says (Ethic. vi, 5) that "in art it is better to err voluntarily than involuntarily, whereas in the case of prudence, as of the virtues, it is worse." Now the moral virtues, of which he is treating there, are in the appetitive faculty, whereas art is in the reason. Therefore prudence is in the appetitive rather than in the rational faculty.

On the contrary, 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.

Reply Obj. 1: As stated above (I, Q. 82, A. 4) the will moves all the faculties to their acts. Now the first act of the appetitive faculty is love, as stated above (I-II, Q. 25, AA. 1, 2). Accordingly prudence is said to be love, not indeed essentially, but in so far as love moves to the act of prudence. Wherefore Augustine goes on to say that "prudence is love discerning aright that which helps from that which hinders us in tending to God." Now love is said to discern because it moves the reason to discern.

Reply Obj. 2: The prudent man considers things afar off, in so far as they tend to be a help or a hindrance to that which has to be done at the present time. Hence it is clear that those things which prudence considers stand in relation to this other, as in relation to the end. Now of those things that are directed to the end there is counsel in the reason, and choice in the appetite, of which two, counsel belongs more properly to prudence, since the Philosopher states (Ethic. vi, 5, 7, 9) that a prudent man "takes good counsel." But as choice presupposes counsel, since it is "the desire for what has been already counselled" (Ethic. iii, 2), it follows that choice can also be ascribed to prudence indirectly, in so far, to wit, as prudence directs the choice by means of counsel.

Reply Obj. 3: The worth of prudence consists not in thought merely, but in its application to action, which is the end of the practical reason. Wherefore if any defect occur in this, it is most contrary to prudence, since, the end being of most import in everything, it follows that a defect which touches the end is the worst of all. Hence the Philosopher goes on to say (Ethic. vi, 5) that prudence is "something more than a merely rational habit," such as art is, since, as stated above (I-II, Q. 57, A. 4) it includes application to action, which application is an act of the will. _______________________

SECOND ARTICLE [II-II, Q. 47, Art. 2]

Whether Prudence Belongs to the Practical Reason Alone or Also to the Speculative Reason?

Objection 1: It would seem that prudence belongs not only to the practical, but also to the speculative reason. For it is written (Prov. 10:23): "Wisdom is prudence to a man." Now wisdom consists chiefly in contemplation. Therefore prudence does also.

Obj. 2: Further, Ambrose says (De Offic. i, 24): "Prudence is concerned with the quest of truth, and fills us with the desire of fuller knowledge." Now this belongs to the speculative reason. Therefore prudence resides also in the speculative reason.

Obj. 3: Further, the Philosopher assigns art and prudence to the same part of the soul (Ethic. vi, 1). Now art may be not only practical but also speculative, as in the case of the liberal arts. Therefore prudence also is both practical and speculative.

On the contrary, 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.

Reply Obj. 1: As stated above (Q. 45, AA. 1, 3), wisdom considers the absolutely highest cause: so that the consideration of the highest cause in any particular genus belongs to wisdom in that genus. Now in the genus of human acts the highest cause is the common end of all human life, and it is this end that prudence intends. For the Philosopher says (Ethic. vi, 5) that just as he who reasons well for the realization of a particular end, such as victory, is said to be prudent, not absolutely, but in a particular genus, namely warfare, so he that reasons well with regard to right conduct as a whole, is said to be prudent absolutely. Wherefore it is clear that prudence is wisdom about human affairs: but not wisdom absolutely, because it is not about the absolutely highest cause, for it is about human good, and this is not the best thing of all. And so it is stated significantly that "prudence is wisdom for man," but not wisdom absolutely.

Reply Obj. 2: Ambrose, and Tully also (De Invent. ii, 53) take the word prudence in a broad sense for any human knowledge, whether speculative or practical. And yet it may also be replied that the act itself of the speculative reason, in so far as it is voluntary, is a matter of choice and counsel as to its exercise; and consequently comes under the direction of prudence. On the other hand, as regards its specification in relation to its object which is the "necessary true," it comes under neither counsel nor prudence.

Reply Obj. 3: Every application of right reason in the work of production belongs to art: but to prudence belongs only the application of right reason in matters of counsel, which are those wherein there is no fixed way of obtaining the end, as stated in Ethic. iii, 3. Since then, the speculative reason makes things such as syllogisms, propositions and the like, wherein the process follows certain and fixed rules, consequently in respect of such things it is possible to have the essentials of art, but not of prudence; and so we find such a thing as a speculative art, but not a speculative prudence. _______________________

THIRD ARTICLE [II-II, Q. 47, Art. 3]

Whether Prudence Takes Cognizance of Singulars?

Objection 1: It would seem that prudence does not take cognizance of
singulars. For prudence is in the reason, as stated above (AA. 1, 2).
But "reason deals with universals," according to Phys. i, 5.
Therefore prudence does not take cognizance except of universals.

Obj. 2: Further, singulars are infinite in number. But the reason cannot comprehend an infinite number of things. Therefore prudence which is right reason, is not about singulars.

Obj. 3: Further, particulars are known by the senses. But prudence is not in a sense, for many persons who have keen outward senses are devoid of prudence. Therefore prudence does not take cognizance of singulars.

On the contrary, 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 (A. 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.

Reply Obj. 1: Reason first and chiefly is concerned with universals, and yet it is able to apply universal rules to particular cases: hence the conclusions of syllogisms are not only universal, but also particular, because the intellect by a kind of reflection extends to matter, as stated in De Anima iii.

Reply Obj. 2: It is because the infinite number of singulars cannot be comprehended by human reason, that "our counsels are uncertain" (Wis. 9:14). Nevertheless experience reduces the infinity of singulars to a certain finite number which occur as a general rule, and the knowledge of these suffices for human prudence.

Reply Obj. 3: As the Philosopher says (Ethic. vi, 8), prudence does not reside in the external senses whereby we know sensible objects, but in the interior sense, which is perfected by memory and experience so as to judge promptly of particular cases. This does not mean however that prudence is in the interior sense as in its princip[al] subject, for it is chiefly in the reason, yet by a kind of application it extends to this sense. _______________________
