Whether the acts of the external members are commanded?

❌ Objection 1 : It would seem that the members of the body do not obey reason as to their acts. For it is evident that the members of the body are more distant from the reason, than the powers of the vegetal soul. But the powers of the vegetal soul do not obey reason, as stated above (Article [8]). Therefore much less do the members of the body obey.

❌ Objection 2 : Further, the heart is the principle of animal movement. But the movement of the heart is not subject to the command of reason: for Gregory of Nyssa [*Nemesius, De Nat. Hom. xxii.] says that "the pulse is not controlled by reason." Therefore the movement of the bodily members is not subject to the command of reason.

❌ Objection 3 : Further, Augustine says (De Civ. Dei xiv, 16) that "the movement of the genital members is sometimes inopportune and not desired; sometimes when sought it fails, and whereas the heart is warm with desire, the body remains cold." Therefore the movements of the members are not obedient to reason.
