SECOND ARTICLE [II-II, Q. 50, Art. 2]

Whether Political Prudence Is Fittingly Accounted a Part of Prudence?

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.

Obj. 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.

Obj. 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 Obj. 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 Obj. 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 Obj. 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.
