QUESTION 6

OF THE VOLUNTARY AND THE INVOLUNTARY

(In Eight Articles)

Since therefore Happiness is to be gained by means of certain acts,

we must in due sequence consider human acts, in order to know by what

acts we may obtain Happiness, and by what acts we are prevented from

obtaining it. But because operations and acts are concerned with

things singular, consequently all practical knowledge is incomplete

unless it take account of things in detail. The study of Morals,

therefore, since it treats of human acts, should consider first the

general principles; and secondly matters of detail.

In treating of the general principles, the points that offer

themselves for our consideration are (1) human acts themselves; (2)

their principles. Now of human acts some are proper to man; others

are common to man and animals. And since Happiness is man's proper

good, those acts which are proper to man have a closer connection

with Happiness than have those which are common to man and the other

animals. First, then, we must consider those acts which are proper to

man; secondly, those acts which are common to man and the other

animals, and are called Passions. The first of these points offers a

twofold consideration: (1) What makes a human act? (2) What

distinguishes human acts?

And since those acts are properly called human which are voluntary,

because the will is the rational appetite, which is proper to man; we

must consider acts in so far as they are voluntary.

First, then, we must consider the voluntary and involuntary in

general; secondly, those acts which are voluntary, as being elicited

by the will, and as issuing from the will immediately; thirdly, those

acts which are voluntary, as being commanded by the will, which issue

from the will through the medium of the other powers.

And because voluntary acts have certain circumstances, according to

which we form our judgment concerning them, we must first consider

the voluntary and the involuntary, and afterwards, the circumstances

of those acts which are found to be voluntary or involuntary. Under

the first head there are eight points of inquiry:

(1) Whether there is anything voluntary in human acts?

(2) Whether in irrational animals?

(3) Whether there can be voluntariness without any action?

(4) Whether violence can be done to the will?

(5) Whether violence causes involuntariness?

(6) Whether fear causes involuntariness?

(7) Whether concupiscence causes involuntariness?

(8) Whether ignorance causes involuntariness?
