Prudence - Article 8

Article 8. Whether command is the chief act of prudence?

 

The Philosopher says (Ethic. vi, 10) that "prudence commands."

I answer that, Prudence is "right reason applied to action," as stated above (Article 2). Hence that which is the chief act of reason in regard to action must needs be the chief act of prudence. Now there are three such acts. The first is "to take counsel," which belongs to discovery, for counsel is an act of inquiry, as stated above (I-II, 14, 1). The second act is "to judge of what one has discovered," and this is an act of the speculative reason. But the practical reason, which is directed to action, goes further, and its third act is "to command," which act consists in applying to action the things counselled and judged. And since this act approaches nearer to the end of the practical reason, it follows that it is the chief act of the practical reason, and consequently of prudence.
In confirmation of this we find that the perfection of art consists in judging and not in commanding: wherefore he who sins voluntarily against his craft is reputed a better craftsman than he who does so involuntarily, because the former seems to do so from right judgment, and the latter from a defective judgment. On the other hand it is the reverse in prudence, as stated in Ethic. vi, 5, for it is more imprudent to sin voluntarily, since this is to be lacking in the chief act of prudence, viz. command, than to sin involuntarily.
