THIRD ARTICLE [III, Q. 18, Art. 3]

Whether in Christ There Were Two Wills As Regards the Reason?

Objection 1: It would seem that in Christ there were two wills as

regards the reason. For Damascene says (De Fide Orth. ii, 22) that

there is a double will in man, viz. the natural will which is called

_thelesis_, and the rational will which is called _boulesis_. Now

Christ in His human nature had whatever belongs to the perfection of

human nature. Hence both the foregoing wills were in Christ.

Obj. 2: Further, the appetitive power is diversified in man by the

difference of the apprehensive power, and hence according to the

difference of sense and intellect is the difference of sensitive and

intellective appetite in man. But in the same way as regards man's

apprehension, we hold the difference of reason and intellect; both of

which were in Christ. Therefore there was a double will in Him, one

intellectual and the other rational.

Obj. 3: Further, some [*Hugh of St. Victor, De Quat. Volunt. Christ.]

ascribe to Christ "a will of piety," which can only be on the part of

reason. Therefore in Christ on the part of reason there are several

wills.

_On the contrary,_ In every order there is one first mover. But the

will is the first mover in the genus of human acts. Therefore in one

man there is only one will, properly speaking, which is the will of

reason. But Christ is one man. Therefore in Christ there is only one

human will.

_I answer that,_ As stated above (A. 1, ad 3), the will is sometimes

taken for the power, and sometimes for the act. Hence if the will is

taken for the act, it is necessary to place two wills, i.e. two

species of acts of the will in Christ on the part of the reason. For

the will, as was said in the I-II, Q. 8, AA. 2, 3, regards both the

end and the means; and is affected differently towards both. For

towards the end it is borne simply and absolutely, as towards what is

good in itself; but towards the means it is borne under a certain

relation, as the goodness of the means depends on something else.

Hence the act of the will, inasmuch as it is drawn to anything

desired of itself, as health, which act is called by Damascene

_thelesis_--i.e. simple will, and by the masters "will as nature," is

different from the act of the will as it is drawn to anything that is

desired only in order to something else, as to take medicine; and

this act of the will Damascene calls _boulesis_--i.e. counseling

will, and the masters, "will as reason." But this diversity of acts

does not diversify the power, since both acts regard the one common

ratio of the object, which is goodness. Hence we must say that if we

are speaking of the power of the will, in Christ there is but one

human will, essentially so called and not by participation; but if we

are speaking of the will as an act, we thus distinguish in Christ a

will as nature, which is called _thelesis_, and a will as reason,

which is called _boulesis_.

Reply Obj. 1: These two wills do not diversify the power but only the

act, as we have said.

Reply Obj. 2: The intellect and the reason are not distinct powers,

as was said in the First Part (Q. 79, A. 8).

Reply Obj. 3: The "will of piety" would not seem to be distinct from

the will considered as nature, inasmuch as it shrinks from another's

evil, absolutely considered.
