Whether the act of the sensitive appetite is commanded?

❌ Objection 1 : It would seem that the act of the sensitive appetite is not commanded. For the Apostle says (Rm. 7:15): "For I do not that good which I will": and a gloss explains this by saying that man lusts, although he wills not to lust. But to lust is an act of the sensitive appetite. Therefore the act of the sensitive appetite is not subject to our command.

❌ Objection 2 : Further, corporeal matter obeys God alone, to the effect of formal transmutation, as was shown in the FP, Question [65], Article [4]; FP, Question [91], Article [2]; FP, Question [110], Article [2]. But the act of the sensitive appetite is accompanied by a formal transmutation of the body, consisting in heat or cold. Therefore the act of the sensitive appetite is not subject to man's command.

❌ Objection 3 : Further, the proper motive principle of the sensitive appetite is something apprehended by sense or imagination. But it is not always in our power to apprehend something by sense or imagination. Therefore the act of the sensitive appetite is not subject to our command.
