SECOND ARTICLE [II-II, Q. 51, Art. 2]

Whether _Euboulia_ Is a Special Virtue, Distinct from Prudence?

Objection 1: It would seem that _euboulia_ is not a distinct virtue

from prudence. For, according to the Philosopher (Ethic. vi, 5), the

"prudent man is, seemingly, one who takes good counsel." Now this

belongs to _euboulia_ as stated above. Therefore _euboulia_ is not

distinct from prudence.

Obj. 2: Further, human acts to which human virtues are directed, are

specified chiefly by their end, as stated above (I-II, Q. 1, A. 3; Q.

18, AA. 4, 6). Now _euboulia_ and prudence are directed to the same

end, as stated in _Ethic._ vi, 9, not indeed to some particular end,

but to the common end of all life. Therefore _euboulia_ is not a

distinct virtue from prudence.

Obj. 3: Further, in speculative sciences, research and decision

belong to the same science. Therefore in like manner these belong to

the same virtue in practical matters. Now research belongs to

_euboulia,_ while decision belongs to prudence. There _euboulia_ is

not a distinct virtue from prudence.

_On the contrary,_ Prudence is preceptive, according to _Ethic._ vi,

10. But this does not apply to _euboulia_. Therefore _euboulia_ is a

distinct virtue from prudence.

_I answer that,_ As stated above (A. 1), virtue is properly directed

to an act which it renders good; and consequently virtues must differ

according to different acts, especially when there is a different

kind of goodness in the acts. For, if various acts contained the same

kind of goodness, they would belong to the same virtue: thus the

goodness of love, desire and joy depends on the same, wherefore all

these belong to the same virtue of charity.

Now acts of the reason that are ordained to action are diverse, nor

have they the same kind of goodness: since it is owing to different

causes that a man acquires good counsel, good judgment, or good

command, inasmuch as these are sometimes separated from one another.

Consequently _euboulia_ which makes man take good counsel must needs

be a distinct virtue from prudence, which makes man command well. And

since counsel is directed to command as to that which is principal,

so _euboulia_ is directed to prudence as to a principal virtue,

without which it would be no virtue at all, even as neither are the

moral virtues without prudence, nor the other virtues without charity.

Reply Obj. 1: It belongs to prudence to take good counsel by

commanding it, to _euboulia_ by eliciting it.

Reply Obj. 2: Different acts are directed in different degrees to the

one end which is "a good life in general" [*Ethic. vi, 5]: for

counsel comes first, judgment follows, and command comes last. The

last named has an immediate relation to the last end: whereas the

other two acts are related thereto remotely. Nevertheless these have

certain proximate ends of their own, the end of counsel being the

discovery of what has to be done, and the end of judgment, certainty.

Hence this proves not that _euboulia_ is not a distinct virtue from

prudence, but that it is subordinate thereto, as a secondary to a

principal virtue.

Reply Obj. 3: Even in speculative matters the rational science of

dialectics, which is directed to research and discovery, is distinct

from demonstrative science, which decides the truth.
