Whether {synesis} (judging well according to common law) is a virtue?

❌ Objection 1 : It would seem that {synesis} is not a virtue. Virtues are not in us by nature, according to Ethic. ii, 1. But {synesis} (judging well according to common law) is natural to some, as the Philosopher states (Ethic. vi, 11). Therefore {synesis} (judging well according to common law) is not a virtue.

❌ Objection 2 : Further, as stated in the same book (10), {synesis} (judging well according to common law) is nothing but "a faculty of judging." But judgment without command can be even in the wicked. Since then virtue is only in the good, it seems that {synesis} (judging well according to common law) is not a virtue.

❌ Objection 3 : Further, there is never a defective command, unless there be a defective judgment, at least in a particular matter of action; for it is in this that every wicked man errs. If therefore {synesis} (judging well according to common law) be reckoned a virtue directed to good judgment, it seems that there is no need for any other virtue directed to good command: and consequently prudence would be superfluous, which is not reasonable. Therefore {synesis} (judging well according to common law) is not a virtue.
