Part 1616

ges something to be fitting and good, which he would not judge thus were it not for the passion. Now this influence of a passion on man occurs in two ways. First, so that his reason is wholly bound, so that he has not the use of reason: as happens in those who through a violent access of anger or concupiscence become furious or insane, just as they may from some other bodily disorder; since such like passions do not take place without some change in the body. And of such the same is to be said as of irrational animals, which follow, of necessity, the impulse of their passions: for in them there is neither movement of reason, nor, consequently, of will.

Sometimes, however, the reason is not entirely engrossed by the passion, so that the judgment of reason retains, to a certain extent, its freedom: and thus the movement of the will remains in a certain degree. Accordingly in so far as the reason remains free, and not subject to the passion, the will's movement, which also remains, does not tend of necessity to that whereto the passion inclines it. Consequently, either there is no movement of the will in that man, and the passion alone holds its sway: or if there be a movement of the will, it does not necessarily follow the passion.
