Whether the mean of moral virtue is the real mean, or the rational mean?

❌ Objection 1 : It would seem that the mean of moral virtue is not the rational mean, but the real mean. For the good of moral virtue consists in its observing the mean. Now, good, as stated in Metaph. ii, text. 8, is in things themselves. Therefore the mean of moral virtue is a real mean.

❌ Objection 2 : Further, the reason is a power of apprehension. But moral virtue does not observe a mean between apprehensions, but rather a mean between operations or passions. Therefore the mean of moral virtue is not the rational, but the real mean.

❌ Objection 3 : Further, a mean that is observed according to arithmetical or geometrical proportion is a real mean. Now such is the mean of justice, as stated in Ethic. v, 3. Therefore the mean of moral virtue is not the rational, but the real mean.
