Of the Acts Commanded by the Will

Of the Acts Commanded by the Will — St. Thomas Aquinas asks: Whether command is an act of the reason or of the will?; Whether command belongs to irrational animals?; Whether use precedes command?; Whether command and the commanded act are one act, or distinct?; Whether the act of the will is commanded?; Whether the act of the reason is commanded?; Whether the act of the sensitive appetite is commanded?; Whether the act of the vegetal soul is commanded?; Whether the acts of the external members are commanded?.

We must now consider the acts commanded by the will; under which head there are nine points of inquiry:

Article 1: Whether command is an act of the reason or of the will?

Gregory of Nyssa [*Nemesius, De Nat. Hom. xvi.] and the Philosopher (Ethic. i, 13) say that "the appetite obeys reason." Therefore command is an act of the reason.

Command is an act of the reason presupposing, however, an act of the will. In proof of this, we must take note that, since the acts of the reason and of the will can be brought to bear on one another, in so far as the reason reasons about willing, and the will wills to reason, the result is that the act of the reason precedes the act of the will, and conversely. And since the power of the preceding act continues in the act that follows, it happens sometimes that there is an act of the will in so far as it retains in itself something of an act of the reason, as we have stated in reference to use and choice; and conversely, that there is an act of the reason in so far as it retains in itself something of an act of the will.

Now, command is essentially indeed an act of the reason: for the commander orders the one commanded to do something, by way of intimation or declaration; and to order thus by intimating or declaring is an act of the reason. Now the reason can intimate or declare something in two ways. First, absolutely: and this intimation is expressed by a verb in the indicative mood, as when one person says to another: "This is what you should do." Sometimes, however, the reason intimates something to a man by moving him thereto; and this intimation is expressed by a verb in the imperative mood; as when it is said to someone: "Do this." Now the first mover, among the powers of the soul, to the doing of an act is the will, as stated above (). Since therefore the second mover does not move, save in virtue of the first mover, it follows that the very fact that the reason moves by commanding, is due to the power of the will. Consequently it follows that command is an act of the reason, presupposing an act of the will, in virtue of which the reason, by its command, moves (the power) to the execution of the act.

Article 2: Whether command belongs to irrational animals?

Command is an act of reason, as stated above (). But in irrational animals there is no reason. Neither, therefore, is there command.

To command is nothing else than to direct someone to do something, by a certain motion of intimation. Now to direct is the proper act of reason. Wherefore it is impossible that irrational animals should command in any way, since they are devoid of reason.

Article 3: Whether use precedes command?

Damascene says (De Fide Orth. ii, 22) that impulse to action precedes use. But impulse to operation is given by command. Therefore command precedes use.

use of that which is directed to the end, in so far as it is in the reason referring this to the end, precedes choice, as stated above (). Wherefore still more does it precede command. On the other hand, use of that which is directed to the end, in so far as it is subject to the executive power, follows command; because use in the user is united to the act of the thing used; for one does not use a stick before doing something with the stick. But command is not simultaneous with the act of the thing to which the command is given: for it naturally precedes its fulfilment, sometimes, indeed, by priority of time. Consequently it is evident that command precedes use.

Article 4: Whether command and the commanded act are one act, or distinct?

The Philosopher says (Topic. iii, 2) that "where one thing is by reason of another, there is but one." But there is no commanded act unless by reason of the command. Therefore they are one.

Nothing prevents certain things being distinct in one respect, and one in another respect. Indeed, every multitude is one in some respect, as Dionysius says (Div. Nom. xiii). But a difference is to be observed in this, that some are simply many, and one in a particular aspect: while with others it is the reverse. Now "one" is predicated in the same way as "being." And substance is being simply, whereas accident or being "of reason" is a being only in a certain respect. Wherefore those things that are one in substance are one simply, though many in a certain respect. Thus, in the genus substance, the whole composed of its integral or essential parts, is one simply: because the whole is being and substance simply, and the parts are being and substances in the whole. But those things which are distinct in substance, and one according to an accident, are distinct simply, and one in a certain respect: thus many men are one people, and many stones are one heap; which is unity of composition or order. In like manner also many individuals that are one in genus or species are many simply, and one in a certain respect: since to be one in genus or species is to be one according to the consideration of the reason.

Now just as in the genus of natural things, a whole is composed of matter and form (e.g. man, who is one natural being, though he has many parts, is composed of soul and body); so, in human acts, the act of a lower power is in the position of matter in regard to the act of a higher power, in so far as the lower power acts in virtue of the higher power moving it: for thus also the act of the first mover is as the form in regard to the act of its instrument. Hence it is evident that command and the commanded act are one human act, just as a whole is one, yet in its parts, many.

Article 5: Whether the act of the will is commanded?

Whatever is in our power, is subject to our command. But the acts of the will, most of all, are in our power; since all our acts are said to be in our power, in so far as they are voluntary. Therefore the acts of the will are commanded by us.

As stated above (), command is nothing else than the act of the reason directing, with a certain motion, something to act. Now it is evident that the reason can direct the act of the will: for just as it can judge it to be good to will something, so it can direct by commanding man to will. From this it is evident that an act of the will can be commanded.

Article 6: Whether the act of the reason is commanded?

That which we do of our free-will, can be done by our command. But the acts of the reason are accomplished through the free-will: for Damascene says (De Fide Orth. ii, 22) that "by his free-will man inquires, considers, judges, approves." Therefore the acts of the reason can be commanded.

Since the reason reacts on itself, just as it directs the acts of other powers, so can it direct its own act. Consequently its act can be commanded.

But we must take note that the act of the reason may be considered in two ways. First, as to the exercise of the act. And considered thus, the act of the reason can always be commanded: as when one is told to be attentive, and to use one's reason. Secondly, as to the object; in respect of which two acts of the reason have to be noticed. One is the act whereby it apprehends the truth about something. This act is not in our power: because it happens in virtue of a natural or supernatural light. Consequently in this respect, the act of the reason is not in our power, and cannot be commanded. The other act of the reason is that whereby it assents to what it apprehends. If, therefore, that which the reason apprehends is such that it naturally assents thereto, e.g. the first principles, it is not in our power to assent or dissent to the like: assent follows naturally, and consequently, properly speaking, is not subject to our command. But some things which are apprehended do not convince the intellect to such an extent as not to leave it free to assent or dissent, or at least suspend its assent or dissent, on account of some cause or other; and in such things assent or dissent is in our power, and is subject to our command.

Article 7: Whether the act of the sensitive appetite is commanded?

Gregory of Nyssa [*Nemesius, De Nat. Hom. xvi.] says: "That which obeys reason is twofold, the concupiscible and the irascible," which belong to the sensitive appetite. Therefore the act of the sensitive appetite is subject to the command of reason.

An act is subject to our command, in so far as it is in our power, as stated above (). Consequently in order to understand in what manner the act of the sensitive appetite is subject to the command of reason, we must consider in what manner it is in our power. Now it must be observed that the sensitive appetite differs from the intellective appetite, which is called the will, in the fact that the sensitive appetite is a power of a corporeal organ, whereas the will is not. Again, every act of a power that uses a corporeal organ, depends not only on a power of the soul, but also on the disposition of that corporeal organ: thus the act of vision depends on the power of sight, and on the condition of the eye, which condition is a help or a hindrance to that act. Consequently the act of the sensitive appetite depends not only on the appetitive power, but also on the disposition of the body.

Now whatever part the power of the soul takes in the act, follows apprehension. And the apprehension of the imagination, being a particular apprehension, is regulated by the apprehension of reason, which is universal; just as a particular active power is regulated by a universal active power. Consequently in this respect the act of the sensitive appetite is subject to the command of reason. On the other hand, condition or disposition of the body is not subject to the command of reason: and consequently in this respect, the movement of the sensitive appetite is hindered from being wholly subject to the command of reason.

Moreover it happens sometimes that the movement of the sensitive appetite is aroused suddenly in consequence of an apprehension of the imagination of sense. And then such movement occurs without the command of reason: although reason could have prevented it, had it foreseen. Hence the Philosopher says (Polit. i, 2) that the reason governs the irascible and concupiscible not by a "despotic supremacy," which is that of a master over his slave; but by a "politic and royal supremacy," whereby the free are governed, who are not wholly subject to command.

Article 8: Whether the act of the vegetal soul is commanded?

Gregory of Nyssa [*Nemesius, De Nat. Hom. xxii.] sats that "the nutritive and generative power is one over which the reason has no control."

Some acts proceed from the natural appetite, others from the animal, or from the intellectual appetite: for every agent desires an end in some way. Now the natural appetite does not follow from some apprehension, as to the animal and the intellectual appetite. But the reason commands by way of apprehensive power. Wherefore those acts that proceed from the intellective or the animal appetite, can be commanded by reason: but not those acts that proceed from the natural appetite. And such are the acts of the vegetal soul; wherefore Gregory of Nyssa (Nemesius, De Nat. Hom. xxii) says "that generation and nutrition belong to what are called natural powers." Consequently the acts of the vegetal soul are not subject to the command of reason.

Article 9: Whether the acts of the external members are commanded?

Augustine says (Confess. viii, 9): "The mind commands a movement of the hand, and so ready is the hand to obey, that scarcely can one discern obedience from command."

The members of the body are organs of the soul's powers. Consequently according as the powers of the soul stand in respect of obedience to reason, so do the members of the body stand in respect thereof. Since then the sensitive powers are subject to the command of reason, whereas the natural powers are not; therefore all movements of members, that are moved by the sensitive powers, are subject to the command of reason; whereas those movements of members, that arise from the natural powers, are not subject to the command of reason.
