Whether prudence about one's own good is specifically the same as that which extends to the common good?

❌ Objection 1 : It seems that prudence about one's own good is the same specifically as that which extends to the common good. For the Philosopher says (Ethic. vi, 8) that "political prudence, and prudence are the same habit, yet their essence is not the same."

❌ Objection 2 : Further, the Philosopher says (Polit. iii, 2) that "virtue is the same in a good man and in a good ruler." Now political prudence is chiefly in the ruler, in whom it is architectonic, as it were. Since then prudence is a virtue of a good man, it seems that prudence and political prudence are the same habit.

❌ Objection 3 : Further, a habit is not diversified in species or essence by things which are subordinate to one another. But the particular good, which belongs to prudence simply so called, is subordinate to the common good, which belongs to political prudence. Therefore prudence and political prudence differ neither specifically nor essentially.
