that commands them, since they have nothing of their own. But that power is called politic and royal by which a man rules over free subjects, who, though subject to the government of the ruler, have nevertheless something of their own, by reason of which they can resist the orders of him who commands. And so, the soul is said to rule the body by a despotic power, because the members of the body cannot in any way resist the sway of the soul, but at the soul's command both hand and foot, and whatever member is naturally moved by voluntary movement, are moved at once. But the intellect or reason is said to rule the irascible and concupiscible by a politic power: because the sensitive appetite has something of its own, by virtue whereof it can resist the commands of reason. For the sensitive appetite is naturally moved, not only by the estimative power in other animals, and in man by the cogitative power which the universal reason guides, but also by the imagination and sense. Whence it is that we experience that the irascible and concupiscible powers do resist reason, inasmuch as we sense or imagine something pleasant, which reason forbids, or unpleasant, which reason commands. And so from the fact that the irascible and concupiscible resist reason in something, we must not conclude that they do not obey.
Reply Obj. 3: The exterior senses require for action exterior sensible things, whereby they are affected, and the presence of which is not ruled by reason. But the interior powers, both appetitive and apprehensive, do not require exterior things. Therefore they are subject to the command of reason, which can not only incite or modify the affections of the appetitive power, but can also form the phantasms of the imagination.
