Whether the act of the reason is commanded?

Objections

Objection 1 : It would seem that the act of the reason cannot be commanded. For it seems impossible for a thing to command itself. But it is the reason that commands, as stated above (Article [1]). Therefore the act of the reason is not commanded.
Objection 2 : Further, that which is essential is different from that which is by participation. But the power whose act is commanded by reason, is rational by participation, as stated in Ethic. i, 13. Therefore the act of that power, which is essentially rational, is not commanded.
Objection 3 : Further, that act is commanded, which is in our power. But to know and judge the truth, which is the act of reason, is not always in our power. Therefore the act of the reason cannot be commanded.
